A waste gas recovery equipment for waste treatment thermal furnace

Abstract

The invention discloses a waste gas recycling device of a garbage disposal thermalization furnace. The waste gas recycling device of the garbage disposal thermalization furnace structurally comprises a draught fan, a discharge pipeline, a ventilating duct, a spray tower body, a spray head, a water pipe, a dead corner clearing structure, a circulating water pump and a dosing tank, wherein the spray head is installed at the top of the interior of the spray tower body, the spray head communicates with the circulating water pump located on one side of the spray tower body through the water pipe, the circulating water pump and the dosing tank communicates with each other through a pipeline, one side of the discharge pipeline is installed on the other side, opposite to the circulating water pump, of the spray tower body, the draught fan is installed on the other side of the discharge pipeline, and the draught fan is movably clamped with the top of the spray tower body through the ventilating duct. The waste gas recycling device of the garbage disposal thermalization furnace reduces accumulation of reaction products at the bottom of a spray tower on the one hand and scrubs reaction product residuals on a slide slope bypass through a push brush on the other hand mainly through cooperation of the slide slope bypass and the push brush, guarantees that a corner formed between the bottom of the spray tower and the spray tower body cannot become a dead corner where the reaction products accumulate, and prevents the reaction products from causing corrosion to the bottom of the spray tower body.

Description

technical field [0001] The invention relates to the fields of garbage pyrolysis and gasification and garbage wind and sand waste gas treatment, in particular to waste gas recovery equipment for waste treatment thermal furnaces. Background technique [0002] Existing domestic waste is generally disposed of through landfill and incineration, and the waste gas generated after incineration contains sulfur dioxide, suspended particulate matter, nitrogen oxides, toxic trace organic pollutants and other objects. If these objects are directly discharged into the air, it will cause Environmental pollution, so the exhaust gas after garbage incineration will go through the cooling tower (ash discharge) and join the lime storage bin, activated carbon storage --- bag filter (ash discharge) --- wet scrubber (add lye for drainage -- smoke The gas reheater (discharge) is used to purify the exhaust gas produced after combustion. However, when the wet scrubber is sprayed and purified, the com...

[0002] Existing domestic waste is generally disposed of through landfill and incineration, and the waste gas generated after incineration contains sulfur dioxide, suspended particulate matter, nitrogen oxides, toxic trace organic pollutants and other objects. If these objects are directly discharged into the air, it will cause Environmental pollution, so the exhaust gas after garbage incineration will go through the cooling tower (ash discharge) and join the lime storage bin, activated carbon storage --- bag filter (ash discharge) --- wet scrubber (add lye for drainage -- smoke The gas reheater (discharge) is used to purify the exhaust gas produced after combustion. However, when the wet scrubber is sprayed and purified, the combination produced after the chemical reaction will precipitate at the bottom of the tower, and the bottom surface of the tower is vertical to the tower body. The dead corners cannot be completely drained, which will cause corrosion to the scrubber and reduce its service life
