Arctic Star Atmosphere Network: Experts, leaders, peers, good afternoon, we will do a little bit of work for dust removal and denitrification in the past few years, this piece of technology to share, because denitrification and dust removal, including today there are many said desulfurization, these are a systemic problem, the solution to this piece of more than a core accessories, or a certain aspect of the problem, because our company I would like to share with you the progress of research on these two technologies. I would like to share with you the progress of research on these two technologies. I will report to you from the following five aspects.

Anhui Yuanchen Environmental Technology Co., Ltd. Catalyst Division General Manager Wang Guangying

The first main product of our company is a dust bag and denitrification catalyst, as well as green recycling business, and a micro-grid operation we are doing now.

This is the project we have obtained in the past few years, which is at the provincial and municipal level, and we have obtained the post-doctoral workstation in Anhui Province. From this product to solve the existing problems in the field, I am divided into the first technical breakthrough, I will share the technical aspects later, after the technology is available, our product production process quality control is also the core problem, so this piece of our company in the past few years in the introduction of talent and software and hardware additions to make a lot of work in this area, postdoctoral workstation is also one of them, we can not break through the technology without Talented people, this is our research unit with universities, including taxation to bring some breakthroughs, five is five consecutive years to get A-class taxation, three consecutive years to get the average growth rate of taxation of more than 20%.

We mainly do product invention patents around our catalysts and bags to obtain the breakthrough, this is a new product in Anhui Province, at present, our quality assurance can not be separated from some of our equipment and instruments, this is our present we have obtained the provincial technical center and the provincial engineering research center, on this basis to obtain national certification, our experimental system quality control system system certification.

At present, we have also applied for the Anhui testing company, and we will further expand our testing equipment, the introduction of personnel and our testing methods and testing surface to serve more of our peers or needs in the community.

This instrument is divided into dust filter and denitrification catalyst, which is imported from Germany, the German imported thermogravimetric test platform, and our domestic authoritative third-party testing institutions and they choose the same model and the same grade, to ensure that our detected structure will not have some differences with the peers, this is our catalyst-related equipment.

These years, the main choice of instruments imported more sophisticated instrument selection, including this piece for some non-electricity industry outside the site of the optimization of the adjustment of an acceptance of these work, the current non-electricity industry base is relatively small, the detection of this piece is also a great expense, standard with the current top domestic team equipment, we also configured, but also have the ability to make these services, so we are currently this piece is also the service provided to our partners.

To sum up the overall quality of our company, production capacity, recycling of waste catalysts 20,000 capacity, our high-temperature filtration materials 10 million square, hardware in the last year invested in the German AUTEFA imported production line, at present is also the most advanced domestic latest generation of equipment. The advancement is reflected in the manual control, the final performance of our products, the uniformity of our products, uniformity including thickness deviation, we use deviation value to measure in the industry, at present, the CV value of this set of equipment control in 1.5% or less, at present, the first to achieve automatic needle change.

This is our French Andritz production line, this set of manufacturing equipment is also imported, in addition to the above-mentioned reduction of manpower to place neatly is a very good set of equipment, this is the peritoneum with electronic heating. This product has also won the innovation fund of the Ministry of Science and Technology of China. At present, there are 60 or 70 application cases with emissions less than 10 mg, from 600,000 units to small non-electric units.

Including the second technology post-treatment applications, for the current steel design of this low-temperature technology, including the current waterproof and oil-proof technology, aperture control is very strict, the control of our aperture is relatively concentrated.

This is now in the breakthrough of synergistic governance, in the dust bag to do some work, dust removal of mercury, dust removal of dioxin filter media, the owners are more clear, high-temperature hot film technology in all ultra-low emissions above the start of the application.

For different laminating process to do a comparison, without any treatment to do a comparison, the whole emission efficiency and differential pressure this piece is not much increase, the whole efficiency and the other two are not on a level above. This is the process of our lamination dust removal, the lamination is the surface filtration, the traditional filter media is deep filtration. This is a comparison of our lamination photos.

In Germany, after a comparison, we can see that our overall filtration efficiency is more than 5, and currently the laminated filter media is being used in Datang Baqiao Power Plant and Henan Power Plant.

The main advantages are as follows: polyimide fiber, good acidity and alkalinity, compounding and oxidation resistance, as well as wear resistance, alkali resistance and corrosion resistance, high filtration accuracy of trilobal interface, good surface finish and small pressure difference.

This is the test of filtration performance, pore size through our pore size breakthrough is also the pore size control in a relatively concentrated, controlled within 0.34%, 3.46 microns. Through the differential pressure test, we can see that the filtration performance has reached more than 4.9, which is a sharing from the catalyst technology.

For the first technology of our catalysts, because our company has the qualification of regeneration, our idea is to let our catalysts serve for three years and then serve for three or six years, through our way to ensure our catalysts have such a long life, the following are some ways, our innovation is in the formulation. Our innovation is in the formulation. By lattice infiltration, we can change the parameters of our products and multiply the wear and compression resistance.

The second power plant catalyst with wide temperature difference is different from the low temperature catalyst that I will focus on below, because it can operate for a long time at high temperature, between 250 and 260 degrees and 420 degrees.

Because at present, in large power units, we have made some attempts in some small performance above are more successful, the following talk for the steel and sintering industry, low-temperature catalyst breakthrough, the first we have to protect the selection design, low-temperature catalyst prices are relatively high, the catalyst in the end selection is to choose how much, or how to arrange, directly affect the owner input.

So we do enough work on the selection, including field data collection, our catalyst design is not like desulfurization or dust removal, the impact factors are quite complex, including dust content oxygen content water content temperature will affect a to product design, the actual working capacity of the product in addition to accept our software the most cost-effective products, this is a list of our products, at present we from the power and non-power industry from 16-40 holes, yellow part of the current low and medium temperature catalysts with more holes.

Our low and medium temperature catalysts are currently the most worrying problem for owners how to ensure the activity of our products at low temperatures, to use either vanadium or manganese system, some of them play a role in improving the denitrification performance of the product, some of them play a role in anti-inhibition of transformation and some technologies play a role in making these technologies more stable between them.

We also increase the product activity through the product microporous combined with the adjustment, we currently show the product to 63%, the national standard requires 40 square meters, currently more between 45-55, this product compared to the general product more than 15% of the wall pipe surface, on the one hand, to improve the product activity, we have some dust and chemical substances molecularly covered from the inside out, two or three years later part of the surface area is covered, we also have sufficient surface area to improve the activity.

The premise is to ensure that the strength of the product can guarantee the life of the basis. The third issue of our hydrogen sulfate, so that ammonium sulfate can be quickly decomposed, hydrogen sulfate thermal decomposition of the way, below 28 degrees below the rapid decomposition.

At present, the right side is our best upper limit of sulfur dioxide corresponding to different temperatures, from the left side of this chart at present, a conventional product better product catalyst to ensure more than 90% efficiency, the technology above the sulfur dioxide conversion rate control at 0.6%, so as to ensure that the problem of hydrogen sulfate poisoning can be controlled to ensure a three-year life. The fourth one is especially in biomass or special industrial mines where the problem of alkali metals, calcium poisoning is covered poisoning, and arsenic poisoning.

One in our core structure by the deployment of raw materials in the product atomic radius of the larger precious metals, the core technology has a certain repulsive effect, on the other hand, to join some similar structures, this structure and our metal oxides have a similar structure, so that there is a certain detection technology and curing effect, so that you can also avoid the core structure of poisoning. In addition to the introduction of protection devices, now has a very good effect on the adsorption, there are also use cases.

This is a case of partial replacement of our wear and clogging, and this is the site of product certification. Regeneration and recycling of this long story short, the words are clearer to us, mainly to introduce the core of the technology, a bag, at present, the previous recycling of landfill incineration after the economic benefits or national policy above will slowly abolish our thinking is currently we cooperate with Donghua University.

Now into the expansion of production and industrialization process, our ideas will be our waste filter material recycling back after cleaning and separation, and finally applied in public transport, high-speed rail, aircraft or decorative products above.

For planning and recycling I will not talk about, mainly about the process behind, our core pore again and again loosely expanded and reperforated above, microporous inside regardless of dust or chemicals and 100% clean out to ensure that the product activation after having sufficient performance, this piece through vibration, ultrasonic pickling, alkali washing surfactant and heating seven or eight links to control this link, which is not renewable catalyst 90% of the alkali metal can be cleaned.

This is the case of our electric power, this is the case of cloth bag, this is the case of cloth bag in steel, sintering, coking, waste incineration, at present the total case market share of cloth bag is the first, some pressure of catalyst, including 600,000 units, 300,000 units or more, this is the case of catalyst recycling, focus on the low temperature section.

The earliest in Beijing Yanqing heating, in 2015 began to do cases in this area, at that time many owners did not dare to use low temperature catalyst, then we also did some cases in the chemical industry, petrochemical, most of them are before desulfurization, after desulfurization asked to low sulfur content is very little, than before desulfurization is also easy to do a little, focus on the ceramic kiln, at present relatively stable, including now in the biomass have more than a dozen cases running, cement above Is also a breakthrough, we only do honeycomb, the development of 13 holes can fully meet the 70, 80 grams of dust capacity. This is our company and owner partners, just a part of the list. This is our overseas market, this is our listed equity structure.

Here is the focus on the team, the team of our company in the past few years, because our team is relatively young, we have vitality, often organize some sports and exercise activities to enhance the cohesion and hard work ability of everyone, this we often organize some activities. This is the photo of our excellent staff, and every year the excellent staff to go overseas travel opportunities, thank you all, our company technology and company introduction on this side and welcome you to visit our company, hope to have more cooperation with all owners and companies, thank you.
