Embodiment 1

[0021] An adsorbent for exhaust gas purification is composed of the following raw materials in parts by weight: 20 parts of activated carbon fiber, 8 parts of diatom mud, 6 parts of metal oxide, 3 parts of silica sol, and 8 parts of calcium carbonate particles.

[0022] The metal oxide is at least one of zinc oxide, silicon oxide and aluminum oxide. The adsorbent for exhaust gas purification can be obtained by fully mixing the raw materials in the above weight parts.

Embodiment 2

[0024] An adsorbent for exhaust gas purification is composed of the following raw materials in parts by weight: 30 parts of activated carbon fiber, 10 parts of diatom mud, 12 parts of metal oxide, 5 parts of silica sol, and 10 parts of calcium carbonate particles. Other implementations are the same as in Example 1.

Embodiment 3

[0026] An adsorbent for exhaust gas purification is composed of the following raw materials in parts by weight: 25 parts of activated carbon fiber, 9 parts of diatom mud, 9 parts of metal oxide, 4 parts of silica sol, and 9 parts of calcium carbonate particles. Other implementations are the same as in Example 1.

Abstract

A waste gas purification adsorbing agent comprises, by weight, 20-30 parts of activated carbon fibers, 8-10 parts of diatom ooze, 6-12 parts of metal oxide, 3-5 parts of silicon sol and 8-10 parts ofcalcium carbonate granules. The waste gas purification adsorbing agent has the advantages that the adsorbing agent can simultaneously adsorb sulfur dioxide, nitride and organic gas in waste gas and wide in adsorption range and more convenient to use, separate treatment of different components in the waste gas is avoided, the treatment efficiency of the waste gas is improved, and the treatment costof the waste gas is reduced.

Description

technical field [0001] The invention belongs to the field of exhaust gas purification, and in particular relates to an adsorbent for exhaust gas purification. Background technique [0002] Exhaust gas treatment is also called exhaust gas purification. Waste gas treatment refers to industrial sites and factory workshops. [0003] The exhaust gas generated is pretreated before being discharged to the outside, so as to meet the national exhaust gas discharge standards. General waste gas treatment includes organic waste gas treatment, dust waste gas treatment, acid-base waste gas treatment, odor waste gas treatment and air sterilization, disinfection and purification. [0004] The existing activated carbon particles are used as the substrate of the adsorbent, and the adsorption effect often cannot reach the ideal structure, and the adsorption effect on organic gases, sulfur dioxide, nitrides, etc. in the waste gas is not good; The sulfur dioxide and nitrides in the process ar...
