Abstract
The utility model relates to a special apparatus for treating flute containing sulfur dioxide which is designed for using waste to control waste, and reducing the production cost. The utility model is characterized in that a slurry mixing tank is provided with a slag powder supplement inlet and a supernatant circulating inlet port of a precipitation separation pool. The slurry mixing tank leads slurry to a circulating groove, which delivers the slurry to an absorbent inlet of an absorption tower with a pipeline, a smoke inlet and a smoke outlet are respectively arranged on the absorption tower, a lower of the absorption tower leads a reactant to the circulating groove with a pipeline; meanwhile, part of a product of the circulating groove is overflowed to a circulating groove of next grade with a pipeline. So that gas can be finally emptied via two grade serial spraying absorption tower. The device has the advantages of simple method, reasonable process, low production cost, etc. The utility model is applicable to the popularization and application of the improvement in environmental protection of relevant enterprises.
Description
Technical field:
The utility model relates to a kind of isolated plant that sulfur dioxide flue gas is handled that contains, and belongs to International Classification of Patents B01D separation equipment technical field.
Background technology:
At the protection environment, effectively purify the sulfur dioxide flue gas aspect, carried out multiple trial, in patent application formerly, " flue gas desulfurization technique and dedusting pond " appearred, and be with rapid ball formula milk of lime spray absorption cleaning sulfur in smoke, its weak point is: rapid ball needs periodic replacement, must close sintering system during replacing, influence ordinary production, reduce the device operating rate; Increase lime consumption, thereby increase production cost; Reacted gypsum is not fully utilized, and business efficiency is low; The belt filter press power consumption is big in the device, and guipure often ruptures; The PROCESS FOR TREATMENT link is many, influences labor productivity; The container of preparation milk of lime is comparatively clumsy etc.Another kind of use smoke catalytic agent method, its shortcoming are that the mechanical device application is more, technological process complexity, more catalyst changeout trouble.
Goal of the invention:
The purpose of this utility model provides a kind of treatment of wastes with processes of wastes against one another, the raw materials for production cost is low, method is simple, technological process reasonably contains sulfur dioxide flue gas and handles isolated plant.
The utility model is by the following technical solutions:
A kind of sulfur dioxide flue gas that contains is handled isolated plant, it is characterized in that: a slip mixing channel is arranged, the slag powder is set mends inlet and precipitate and separate pond supernatant circulation inlet port; The slip mixing channel is carried slip and is connected to circulating slot with pipeline, circulating slot is delivered to the absorptive tower absorbent import with slip with pipeline, the absorption tower also is respectively arranged with gas approach and outlet, the bottom, absorption tower causes circulating slot with pipeline with reactant, and a part of product of circulating slot uses the pipeline overflow to the next stage circulating slot simultaneously.The gas feed of next stage absorption tower connects upper level absorption tower gas vent with pipeline, to should with pipeline reactant being caused the absorptive tower absorbent import by the level circulating slot, absorbent outlet in bottom, absorption tower causes should the level circulating slot with pipeline, this absorption tower gas vent carries out emptying or causes the gas feed of next stage absorption tower going simultaneously, and this grade circulating slot causes the partial reaction product in precipitate and separate pond or the next stage circulating slot with pipeline and goes.The precipitate and separate pond causes slip mixing channel supernatant circulation inlet port with supernatant with pipeline, isolates the reactant that reacts completely simultaneously.
Above-mentioned first grade absorption tower and two-level absorption tower are the two-stage tandem spray column, and are packless void tower, and are furnished with the impacting type spray thrower of a plurality of layerings respectively.
All is furnished with strong mixer in above-mentioned two circulating slots.
Slip is that the slag powder and the water of 120～250 order sizes is made into, and water and slag weight ratio are 2～5: 1, and slag is the slag that non-ferrous metals smelting works, ferrous metal smelting factory, power plant or oil plant are abandoned.
Facts have proved, be effective aspect the treatment of wastes with processes of wastes against one another with device of the present utility model.At first, the discharging of sulfur dioxide has obtained stabilizing effective control; Secondly, remedied the deficiency that rapid ball formula milk of lime spray column purifies the sulfur dioxide flue gas technology; The 3rd, improved utilization ratio of device and labor productivity, small investment, cost is low, and is profitable.The treatment of wastes with processes of wastes against one another has brought more economic benefit to enterprise.
