Desulfurization is an important energy-saving and environmentally friendly technology, whether it is the industrial discharge of bricks or the discharge of coal after combustion. The desulfurization technology is to fix the sulfur element in coal to a solid by calcium or the like to prevent SO2 from being generated during combustion. Manager, 010-57182232. At present, the Ministry of Environmental Protection and the General Administration of Quality Supervision, Inspection and Quarantine have issued new emission standards. Pollutant Discharge Standards (GB29630-2013). By implementing the “Brick and Tile Industry Air Pollutant Emission Standardsâ€, by 2016, particulate matter and sulfur dioxide can be reduced by 836,000 tons and 486,000 tons. The reduction of nitrogen oxides is mainly achieved through energy conservation and consumption reduction. Combined with the actual situation in China, Beijing Zhisheng Weihua Chemical Co., Ltd. specializing in desulfurization and dust removal and anti-corrosion coatings company, the company's sales of anti-corrosion has further increased.

Desulfurization is an important energy-saving and environmentally friendly technology, whether it is the industrial discharge of bricks or the discharge of coal after combustion. The desulfurization technology is to fix the sulfur element in coal to a solid by calcium or the like to prevent SO2 from being formed during combustion. The desulfurization method before desulfurization can be generally classified into three types: desulfurization before combustion, desulfurization during combustion, and desulfurization after combustion. The method of desulfurization is limestone calcium method: including wet flue gas desulfurization/semi-dry method (Alstom's NID)/dry method (RCFB) and (CFB), ammonia method: less used, more in petrochemical power plants Magnesium method: a method that can regenerate the absorbent. It seems that there is no domestic method. The seawater method: it should be arranged at the seaside. In the process of desulfurization, it has the characteristics of alternating acid and alkali valence, so the equipment metal is seriously corroded and the anti-corrosion conditions are demanding. In recent years, the development and production of ZS-1041 Zhisheng Flue Gas Anticorrosive Coatings, developed and produced by Beijing Zhisheng Weihua Chemical Co., Ltd. in Dongtieying, Fengtai District, Beijing, has been successfully applied. It has amazing desulfurization, condensed water corrosion and anticorrosion effects, and temperature resistance. High, light coating, abrasion resistant to dust scouring, acid and alkali resistance, good thermal expansion and contraction performance, strong adhesion, long service life and good durability. Damaged coating can be easily repaired. Especially when the humidity of the flue gas is high, the corrosive medium contained in the saturated flue gas is more corrosive under the action of the pressure and humidity of the flue gas. The ZS-1041 Zhisheng flue gas anticorrosive coating is dense and resistant. High temperature and high humidity flue gas corrosion effect is better.
The dust removal industrial technology is a mechanical process of dusty industrial waste gas or pulverization, sieving, conveying, blasting, etc. generated by solid materials, or generated in combustion, high-temperature melting and chemical reaction, and has a large particle size and the same chemical composition as the original solid material. Dust, which contains small amounts of soot and chemical properties that are different from the substances from which it is formed. According to the collection mechanism, it can be divided into mechanical dust collector, electrostatic precipitator, filter dust collector and washing dust collector. The ZS-1041 Zhisheng Weihua flue gas anticorrosive coating coating developed by Beijing Zhisheng Weihua Company has been successfully applied. The coating is amazingly resistant to high temperature flue gas, anti-chimney flue condensation water corrosion effect, high temperature resistance, high hardness and wear resistance. It has good acid and alkali resistance and good expansion coefficient. It can be used for more than 10 years. ZS-1041 Zhisheng flue gas anticorrosive coating is hard and wear resistant, resistant to temperature changes, high adhesion, especially resistant to sulfur in dust removal. The metal reacts with elemental sulfur at a high temperature of 240 ° C - 360 ° C and the oxidation reaction of the sulfide product in air at 95 ° C. The metal high temperature sulfur corrosion product is mainly FeS2, etc. The higher the vulcanization temperature and oxidation temperature, the more corrosion occurs during vulcanization. serious. In the dust removal equipment, the thermodynamics and kinetics of the high temperature sulfur corrosion of the metal material and the high temperature sulfur corrosion resistance of the metal material.
In the desulfurization and dedusting industrial equipment, the high-standard Zhisheng ZS-1041 flue gas anticorrosive coating for reference design standards is: 1, ZS-1041 flue gas anticorrosive coating high temperature resistance: coating temperature can reach 750 ° C; 2, ZS-1041 Flue gas anti-corrosion coating acid and alkali corrosion resistance: dilute acid (sulfuric acid, nitric acid, hydrochloric acid) 5% concentration, 80 ° C temperature: 12 days no change; resistance to 30% sulfuric acid: 80 ° C for 15 days no change, no change at room temperature for 30 days; 3, ZS-1041 flue gas anti-corrosion coating water resistance: no change at room temperature for 90 days; 4, ZS-1041 flue gas anti-corrosion coating resistance to peeling: (quick cold heat 250 ° C / water-cooled repeated cycle) 50 times no change; Anti-aging index: no change in humidity resistance test for 500h; 6, ZS-1041 flue gas anticorrosive coating for the longest service life: 13-30 years; 7, ZS-1041 flue gas anticorrosive coating coating hardness is high, anti-smoke dust impact friction ;
