Coke oven flue gas desulfurization cooperative adsorption tar device

Abstract

The invention discloses a coke oven flue gas desulfurization cooperative adsorption tar device, which comprises a tar adsorption box and a combustion pipe. The bottom of the tar adsorption box is equipped with a combustion pipe. During operation, the flue gas rises from a threaded base to a combustion mechanism Connect the external pipe to the vent, so that the combustible gas is transported to the gas nozzle through the delivery pipe, and the combustible gas is ignited by the discharge spark needle, and the insufficiently combusted gas inside the flue gas continues to burn fully. The gas continues upward to the tar adsorption box, and the upper adsorption tube, the extended adsorption tube and the lower adsorption tube in the tar adsorption box are respectively placed with tar adsorbent and calcium oxide, and combined with the water spraying of the spraying mechanism on both sides, the calcium oxide reacts with sulfur dioxide Calcium sulfite precipitates are formed, tar is absorbed by the tar adsorbent, and the remaining gas continues to be discharged upward through the external pipe, so that the flue gas can remove a large amount of tar while desulfurizing, and avoid polluting the environment.

Description

technical field [0001] The invention relates to the technical field of flue gas treatment, in particular to a coke oven flue gas desulfurization cooperative adsorption tar device. Background technique [0002] Flue gas refers to the gaseous substances that pollute the environment produced when coal and other fossil fuels are burned. Because these substances are usually discharged from the flue or chimney, the process of flue gas generation is mostly caused by insufficient use of fuel and incomplete combustion. Because of its high temperature, it can be used as a heat carrier for high-temperature reactions (600-700°C). Its components are mainly nitrogen, carbon dioxide, oxygen, water vapor, and sulfide and other inorganic pollutants, accounting for more than 99%. Dust, powder slag and sulfur dioxide content less than 1%, need to be emptied after being treated by a gas purification device to reduce environmental pollution. If the furnace is not operating normally, it will prod...

[0002] Flue gas refers to the gaseous substances that pollute the environment produced when coal and other fossil fuels are burned. Because these substances are usually discharged from the flue or chimney, the process of flue gas generation is mostly caused by insufficient use of fuel and incomplete combustion. Because of its high temperature, it can be used as a heat carrier for high-temperature reactions (600-700°C). Its components are mainly nitrogen, carbon dioxide, oxygen, water vapor, and sulfide and other inorganic pollutants, accounting for more than 99%. Dust, powder slag and sulfur dioxide content less than 1%, need to be emptied after being treated by a gas purification device to reduce environmental pollution. If the furnace is not operating normally, it will produce carbon monoxide, nitrogen oxide and other harmful gases. The flue gas purification of the prior art After the equipment purifies the harmful gas, a large amount of tar or dust remains in the flue gas, and the discharge of the flue gas with a large amount of tar or dust remaining will still cause environmental pollution, so a purification that can desulfurize and adsorb tar is developed. equipment is very necessary
