Abstract
The utility model relates to a tail gas recovery device, in particular to an absorption treatment device for acidolysis tail gas of the titanium white. A tail gas washing circulation groove, a washing circulation pump, a tail gas washing tower, a multiple baffle demister, a tail gas draught fan and a tail gas chimney are sequentially arranged from bottom to top, wherein the tail gas washing tower is connected with the tail gas washing circulation groove by a pipeline; the tail gas washing circulation groove is connected with the washing circulation pump; the outlet of the washing circulation pump is connected with the tail gas washing tower; the outlet of the tail gas washing tower is connected with the multiple baffle demister; the outlet of the multiple baffle demister is connected with the tail gas draught fan; and the tail gas draught fan is connected with the tail gas chimney. With the adoption of the absorption treatment device, washing water is sprayed in multiple layers, a spraying way of jetting the washing water into the chimney with a plurality of nozzles is adopted for each layer; the washing water is better distributed in the chimney, therefore, the absorption treatment device facilitates the suction of the acidolysis tail gas by the draught fan so as to overcome system resistance, prevents acid mist in an acidolysis workshop from overflowing, and the acidolysis tail gas is washed and then demisted so that the tail gas can reach the standard to be discharged.
Description
Technical field
The utility model relates to a kind of device for recovering tail gas, specifically relates to a kind of titanium dioxide acidolysis tail gas absorption treating device.
Background technology
The processing of titanium dioxide acidolysis tail gas, the filled water scrubber carrying out washing treatment of many employings of past, the method SR is bigger.In recent years, by improvement to introducing technology, many manufacturers begin to take to add the diameter of smokestack, the method that directly adds the processing of water spray changes its version, yet there are many defectives in this mode when carrying out the acidolysis vent gas treatment: 1, because the flow of washings is bigger, distribution in chimney is relatively poor, be unfavorable for acid mist in the acidolysis tail gas, sulfur dioxide, the absorption of sulfur trioxide and dust, amount as short time tail gas is excessive, may cause a large amount of acidolysis tail gas just to leave scrubbing tower without effective processing, cause and handle not exclusively, environment is caused a large amount of pollutions.2, acidolysis tail gas is easily formed bigger resistance, acidolysis tail gas can not qualified discharge, even may cause a large amount of acidolysis tail gas effectively not leave tail gas funnel, causes overflowing of acidolysis workshop acid mist.
The utility model content
At the technical problem that the processing of titanium dioxide acidolysis tail gas in the prior art exists, it is a kind of simple in structure that the purpose of this utility model is to provide, and absorbs treatment effect titanium dioxide acidolysis preferably tail gas absorption treating device.
The technical scheme that the utility model adopted is:
Titanium dioxide acidolysis tail gas absorption treating device, set gradually washing tail gas circulating slot, cleaning circulation pump, tail gas washing tower, multiple baffle demister, tail gas air-introduced machine and tail gas funnel from top to bottom, tail gas washing tower is connected with the washing tail gas circulating slot by pipeline, the washing tail gas circulating slot is connected with cleaning circulation pump, the cycles of washing pump discharge is connected with tail gas washing tower, the tail gas washing tower outlet is connected with multiple baffle demister, the multiple baffle demister outlet is connected with the tail gas air-introduced machine, and the tail gas air-introduced machine connects tail gas funnel.
Compare with acidolysis tail gas treatment device of the prior art, the advantage of the utility model titanium dioxide acidolysis tail gas absorption treating device is,
1, washings is adopted the multilayer spray, every layer of spray mode that adopts a plurality of nozzles in chimney, to spray; The distribution of washings in chimney is better, is beneficial to acidolysis tail gas is added induced draft blower withdraws to overcome SR, prevents that acidolysis workshop acid mist from overflowing, and washing back demist is handled, and makes tail gas energy qualified discharge.
2, adopt independently washings circulation in the design, supplementing water adopts the middle water after Sewage Disposal is handled, and reduces the fresh water consumption.
3, the tail gas that is arranged so that of tail gas air-introduced machine can better pass through tail gas washing tower, and the negative pressure that has increased the tail gas washing tower outlet is beneficial to the amount of the sum of series spray that increases spray.
4, increased multiple baffle demister the tail gas air-introduced machine carried out necessary protection, made air-introduced machine that more better choice can be arranged, such as powerful frequency conversion air-introduced machine, can be along with acidolysis tail gas amount how much carry out the adjusting of power of fan.
5, tail gas funnel the length that has reduced tail gas washing tower is set, the ratio exhaust gas scrubbing tower is smaller on the diameter, also the ratio exhaust gas scrubbing tower is cheaper on the material.
Description of drawings
Fig. 1 is the structural representation of the utility model titanium dioxide acidolysis tail gas absorption treating device.
Among Fig. 1,1-tail gas washing tower, 2-multiple baffle demister, 3-tail gas air-introduced machine, 4-tail gas funnel, 5-cleaning circulation pump, 6-washing tail gas circulating slot.
The specific embodiment
For the ease of it will be appreciated by those skilled in the art that utility model is further described below in conjunction with accompanying drawing.
As shown in Figure 1, titanium dioxide acidolysis tail gas absorption treating device, set gradually washing tail gas circulating slot 6 from top to bottom, cleaning circulation pump 5, tail gas washing tower 1, multiple baffle demister 2, tail gas air-introduced machine 3 and tail gas funnel 4, the following liquid mouth of tail gas washing tower 1 is facing to the inlet of washing tail gas circulating slot 6, washing tail gas circulating slot 6 is connected with cleaning circulation pump 5, cleaning circulation pump 5 outlets are connected with tail gas washing tower 1, tail gas washing tower 1 is connected with multiple baffle demister 2 by the process pipe of DN1800, multiple baffle demister 2 is connected with tail gas air-introduced machine 3 by the process pipe of DN1200, and tail gas air-introduced machine 3 is connected with tail gas funnel 4 by the process pipe of DN1200.
