  1. The humidification outside the tower is only 5% higher than the humidification and cooling inside the tower, but the humidification outside the tower has the advantages of simplifying the system process, reducing investment, and reducing the wall sticking inside the tower.

  2. Activated carbon has a certain effect on the removal of nitrogen oxides. In the test, the high concentration of SOZ in the flue gas affected the removal of NO by activated carbon, and the measured removal rate was about 10%.
  3. The removal rate of HCl by activated carbon is up to 50%, but the removal effect of acid gas H and SO3 is not obvious.

In the test, the desulfurization effect of the cloth bag dust remover was tested, and its desulfurization rate was about 9%.

  1. Analyze the reasons for the low SOZ and NO removal efficiency of activated carbon in the test :(1) ordinary activated carbon is used in the test, which has a low adsorption performance;coconut shell based activated carbon

(2) Due to the limited test conditions, the low input amount of activated carbon per hour in the test means the selected ACIS is lower.

Although the removal efficiency of the activated carbon on SO2 and NO measured in this test is low, the activated carbon used in circulating fluidized bed flue gas desulfurization and denitration has the advantages of simple and reliable process, low system resistance, stable desulfurization and denitration, good economic and environmental protection, NO secondary pollution and so on.coconut shell based activated carbon

The waste gas produced in the production process, mainly of benzene, toluene, xylene, etc., according to the nature of benzene class, this scheme adopts the active carbon as adsorbent to absorb the waste gas, the adsorption bed configuration 2 sets of above commonly, use rotation, when one adsorption bed adsorption of organic adsorption amount of reach regulation, change to another ? adsorption bed for adsorption purification operation, at the same time to take off one in front of the adsorption bed with regeneration.Desorption is carried out by heating under the action of additional steam, and most of the hotgas released by the tail gas is used for desorption and regeneration of adsorbent in the adsorption bed to achieve the utilization of waste heat.The waste gas volatilized from production is sent to the adsorption tower by centrifugal fan with activated carbon as adsorbent. The gas in the tower is processed through the activated carbon filter layer from right to left and from bottom to top, and the purified gas is discharged into the atmosphere through the exhaust pipe.china activated carbon supplier
