Product

Activated carbon desulphurization and denitrification

Name

Activated carbon desulphurization and denitrification

product description

  Due to the adsorption properties of activated carbon, activated carbon can be used as adsorbent in flue gas purification, which can completely remove SOx and other impurities in the flue gas. At the same time, activated carbon can be used as a catalyst in the chemical reaction of NH3 and NOx to achieve denitrification. Therefore, the same kind of active carbon is used to complete the flue gas desulfurization and denitrification technology. Europe is widely used.

  The first generation of cross flow (vertical flow) technology originated in Germany in 1967. Since the technology has the problems of desulphurization, low denitrification efficiency, poor operation safety and high energy consumption, the new European project began to stop in 1989.

  Second generation countercurrent Technology: in view of cross flow technical defects, in 1989, Austria intjia company and German WKV company developed a second generation of countercurrent technology. The technology was engineered by inta company and registered worldwide with CSCR. From 1989, the counter current CSCR desulfurization and denitrification technology was in Europe. To the promotion.

  Characteristics of CSCR desulfurization and denitrification technology

  1、High efficiency of desulphurization and denitrification

  Activated charcoal is in contact with the counter flow of flue gas. The activated carbon flows from top to bottom, and the flue gas flows from the bottom to the bottom. The high SO2 concentration of the flue gas is in contact with the activated carbon before discharge. The activated carbon is well saturated, the regeneration is small, the flue gas desulfurization and denitrification efficiency is high.

  2、Desulphurization and denitrification section of adsorption tower

  The removal efficiency of denitrification and denitrification can reach 99.95%. The SO2 concentration in the flue gas outlet of the desulphurization section can reach 5mg/NM3, that is, after the desulphurization, ammonia does not participate in the desulphurization reaction, the ammonia consumption is less and the side reaction of producing hydrogen sulphate is less, and the denitrification efficiency is high. The denitration efficiency of nittan CSCR technology adsorption tower can reach more than 90%.

  3、System resistance is small, modular design can realize online maintenance.

  The saturated activated carbon and dust are discharged from the lower part of the adsorption tower in time, and the system resistance is small, and the power consumption of the booster fan is saved. A shut-off valve is arranged between the flue gas modules of the adsorption tower module, and the adsorption tower can be scheduled for on-line maintenance.

  4、The height of the bed layer of the adsorbent tower is adjustable

  The height of the bed of the adsorption tower can be adjusted, and the bed height can be adjusted according to the import conditions, so that the power consumption of the booster fan is reduced, and the running cost is reduced.

  5、Module high overlay arrangement to save land

  Each module is made up of single high superposition of desulphurization and denitration, and the two modules are stacked up in high stacking to save land.
