In-furnace white mud deacidification system

Abstract

The invention relates to the technical field of incinerator deacidification, and discloses an in-furnace white mud deacidification system which comprises a feeding hopper, a slurrying tank, a storage tank, an incinerator and a fixing support, vertical stirrers are arranged at the top of the slurrying tank and the top of the storage tank, and the slurrying tank is connected with a first conveying pump through a conveying pipe; the first conveying pump is connected with the storage tank through a first guide pipe. According to the in-furnace white mud deacidification system, through mutual cooperation of the feeding hopper, the slurrying tank, the storage tank, the filter, the vertical stirring machine, the first conveying pump, the second conveying pump, a fixing support, a linear guide rail pair, a spray gun, a spraying cavity, a first guide pipe, a second guide pipe, a third guide pipe, a metal hose and the spray gun, causticized white mud can be directly sprayed into an incinerator; substances in the furnace are deacidified, so that the effects of conveniently treating the causticized white mud and reducing the environment-friendly input cost of a waste incineration enterprise are achieved, and the problems that the causticized white mud is difficult to treat and the environment-friendly input cost of the waste incineration enterprise is relatively high are solved.

Description

technical field [0001] The invention relates to the technical field of incinerator deacidification, in particular to an incinerator lime mud deacidification system. Background technique [0002] The waste incineration industry mainly uses semi-dry deacidification or wet deacidification technology to treat tail gas. The main material used is calcium oxide, and the quality requirements for calcium oxide are relatively high, so the purchase cost is relatively expensive, and in use When the semi-dry method is used to deacidify the tail gas produced by waste incineration, the more lime used, the amount of fly ash treated will increase accordingly, which will increase the cost of fly ash treatment in a disguised form, leading to a further increase in treatment costs, and waste incineration The furnace industry mainly uses atomizers or atomization spray guns to add calcium hydroxide solution in the deacidification tower, and in response to environmental protection requirements, the...

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides an in-furnace lime mud deacidification system, which is capable of directly spraying caustic lime mud into the furnace for deacidification, which reduces the cost of environmental protection investment and prolongs the use of atomization equipment. Long life and effective control of furnace temperature, reducing acid gas in the furnace, reducing the corrosion and thinning rate of the four pipes, etc., solves the difficulty of caustic lime mud treatment, the environmental protection investment cost of waste incineration enterprises is high, and the service life of atomization equipment is short And the acid gas in the furnace is easy to cause the problem of corrosion and thinning of the four tubes in the waste heat furnace
