Embodiment 1

[0047] In a factory producing an environmentally friendly ceramsite filter, the generated exhaust gas is treated using the method of the present invention. Specifically, the present embodiment is processed using the following systems and methods.

[0048] Analysis of governance of sintering ceramic ceramic ceramic particles.

[0049] The plant produces environmentally-friendly ceramics filled with major raw materials, including buildings, river lakes, sludge, including municipal sludge, printing and dyed sludge, paper sludge and food sludge. The contaminants produced are mainly derived from the combustion decomposition of sludge organic components during ceramics of natural gas rotary kiln, mainly ingredients, acid gas (HF, HCl, SO) 2 SO 3 NO x , CO, heavy metals (CD, Ti, Sb, AS, PB, CR, CO, Cu, Mn, Ni, etc.), dioxin, a small amount of volatile organic (methane, ethane, propane, propionic acid, etc.), Some inorganic pollutants (NH 3 , HCN, etc.) and a lot of water vapor.

Abstract

The invention provides a semi-dry desulfurization and dust removal method for sludge sintering ceramic ceramsite waste gas, and relates to the technical field of environmental protection. A semi-dry desulfurization and dust removal system is adopted for waste gas treatment and comprises a desulfurization system, a lime system, a temperature control and humidification system, a dust removal system, an adsorption system and a discharge system. The waste gas treatment process comprises the following steps: desulfurization: introducing the sludge sintering ceramic ceramsite waste gas into a desulfurization tower, and reacting the waste gas with a desulfurization material in the desulfurization tower for desulfurization; dust removal: introducing the desulfurized waste gas into the dust removal system for dust removal; adsorption: introducing the waste gas into the adsorption system to adsorb volatile organic compounds; and discharging: introducing the desulfurized and dedusted waste gas into the discharge system, and discharging the qualified waste gas after detection. The method not only can meet the up-to-standard discharge requirement, but also can simplify the process route, reduce one-time investment and operation cost, reduce the occupied area, and can greatly reduce the generation of wastewater and wet smoke plume.

Description

Technical field [0001] The present invention relates to the field of environmental protection, and in particular, to a sludge sintered ceramic ceramic particulate exhaust gas semi-dry method desulfurization dust removal method. Background technique [0002] The main raw materials of the production of environmentally friendly ceramic ceramics are the construction of dirt, rivers and lakes and sludge, including municipal sludge, printing and dyed sludge, paper sludge, food sintering ceramic ceramic processes to produce a lot. Waste gas (or flue gas), pollutants in exhaust gas mainly derived the combustion decomposition of sludge organic components during ceramics of natural gas rotary kiln, and the main components of exhaust gas are dust, acid gases (HF, HCl, SO 2 SO 3 NO x , CO, heavy metals (CD, Ti, Sb, AS, PB, CR, CO, Cu, Mn, Ni, etc.), dioxin, a small amount of volatile organic (methane, ethane, propane, propionic acid, etc.), Some inorganic pollutants (NH 3 , HCN, etc.) and a ...
