Safe sealed desulfurization reaction tank

Abstract

The invention relates to a safe sealed desulfurization reaction tank which comprises a reaction tank body, an inlet separation plate, baffle plates, partition plates, a gas phase baffle plate and defoaming nozzles; one end of the reaction tank body is provided with a desulfurization liquid inlet, and the other end of the reaction tank body is provided with a desulfurization liquid outlet; the gas phase baffle plate is arranged at one end close to the desulfurized liquid outlet and divides the reaction tank body into a coal gas separation section and a pressure balance section; the inlet separation plate is arranged under the desulfurization liquid inlet; a plurality of baffle plates and partition plates are arranged in the reaction tank body; a plurality of defoaming nozzles are arranged at the top of the reaction tank body; the top of the reaction tank body of the gas separation section is provided with a gas outlet, and the top of the reaction tank body of the pressure balance section is provided with a diffused gas outlet. The problem of environmental pollution caused by direct diffusion of diffused gas of a conventional desulfurization reaction tank is solved, the potential safety hazard that a large amount of coal gas directly enters a pressure balance system is eliminated, and meanwhile, the coal gas entrained by desulfurization liquid entering a downstream regeneration device is effectively reduced.

Description

technical field [0001] The invention relates to the technical field of desulfurization of coke oven gas, in particular to a desulfurization reaction tank used before regeneration of desulfurization liquid after wet oxidation desulfurization of coke oven gas. Background technique [0002] At present, in the wet oxidation desulfurization process of coke oven gas, after the desulfurization liquid absorbs the hydrogen sulfide in the gas in the desulfurization tower, it is usually sent to the desulfurization reaction tank first, and the desulfurization reaction continues in the desulfurization reaction tank, and then the desulfurization liquid is sent to The desulfurization liquid regeneration tank is used for regeneration; the desulfurization reaction tank is usually a horizontal storage tank, and the spray pipe is used to spray and defoam, and the gas brought in by the desulfurization liquid is directly discharged through the release pipe or connected to the pressure balance sys...
