Abstract
The utility model provides an acid regeneration absorption tower with a liquid drop separation function. The acid regeneration absorption tower with the liquid drop separation function comprises a liquid drop separator, wherein the liquid drop separator is situated at the upper portion of the absorption tower, and whirl plate gratings are evenly distributed inside the liquid drop separator. According to the acid regeneration absorption tower with the liquid drop separation function, the acid regeneration absorption tower is additionally provided with a liquid drop separation system with a vertical upper portion based on a traditional absorption tower, and therefore gas-liquid separation effect of smoke of an outlet of the absorption tower is enhanced, content of hydrochloric acid (HCl) in the smoke is reduced, corrosiveness of acid gas against impellers, shafts and other parts of a waste gas fan is lowered, and discharge of pollutants in offgas is reduced.
Description
Technical field
The utility model technology relates to industry environmental protection fields such as iron and steel, chemical industry, is applicable to the absorption tower of cold rolling, silicon steel, stainless steel acid-washing waste liquid regenerative system and chemical industry, particularly a kind of acid regeneration absorption tower with the drop separation function.
Background technology
, silicon steel cold rolling in iron and steel enterprise, waste acid from stainless steel acid washing regenerative system adopt spray roasting mostly; And spray roasting acid regeneration technology both domestic and external is mostly: roaster → venturi preconcentrator → absorption tower → exhaust gas fan → scrubbing tower washing tail gas equipment such as (or secondary venturi), the liquid after absorbing in the absorption tower are about about 85 ℃ 18% hydrochloric acid solution (total HCl content is 190-200g/l).Under the exhaust gas fan suction function, the acid mist gas of a large amount of high temperature can be pumped down to the exhaust gas fan place, and long-time running is not only to very big corrosion of parts generation such as the impeller of blower fan, axles, and when system's fluctuation of service, can influence acid regeneration station exhaust emissions index.
See from the ruuning situation of domestic acid regeneration site; The exhaust gas fan of a lot of acid purification systems is about operation 3-5 (time that has even shorter); Just the situation that draught fan impeller or axle damage owing to seriously corroded can occur, can't turn round and badly influenced the production of pickling line thereby acid purification system also appears in the factory that has.
The enhancing of Along with people's environmental consciousness, also more and more stricter to the requirement of acid regeneration station exhaust emissions, grassroot project especially.HCl concentration in the acid purification system tail gas is one of important detection index, and stable except technology, outside the factors such as absorption tower assimilation effect, good gas-liquid separation effect has very directly influence to the HCl content that reduces in the tail gas.
The utility model content
The purpose of the utility model provides a kind of acid regeneration absorption tower with the drop separation function, can reduce the content of the HCl in the flue gas, has reduced the corrosivity of sour gas to parts such as exhaust gas fan impeller, axles, has reduced the discharging of pollutant in the tail gas.
For achieving the above object, the utility model adopts following technical scheme:
The utility model provides a kind of acid regeneration absorption tower with the drop separation function, comprises liquid drop separator, and wherein, said liquid drop separator is positioned at the top on said absorption tower, and the inside of said liquid drop separator evenly is furnished with the deflection plate grid.
The absorption tower of the utility model, said deflection plate grid corner and top are provided with the dentation liquid opposite with the airflow direction flange that blocks water.
The absorption tower of the utility model, said absorption tower are to give vent to anger in the top.
The absorption tower of the utility model is through increasing the drop separation system that top is vertical on the basis on traditional absorption tower; Strengthen the gas-liquid separation effect of absorption tower outlet flue gas; Thereby the concentration of HCl in the minimizing flue gas; Reduced the corrosivity of sour gas, reduced the discharging of pollutant in the tail gas parts such as exhaust gas fan impeller, axles.

Fig. 1 is the sketch map of a specific embodiment of the utility model;
Fig. 2 is the sketch map of employed deflection plate grid in the specific embodiment of the utility model;
Fig. 3 is the generalized section along the B-B direction of accompanying drawing 2.
Reference numeral: 1: liquid drop separator; 2: nozzle; 3: the deflection plate grid.
The specific embodiment
For the purpose, technical scheme and the advantage that make the utility model is clearer,, the utility model is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
As shown in Figure 1, as a specific embodiment of the utility model, the acid regeneration absorption tower of band drop separation function comprises liquid drop separator 1, is filled with structured packing or Pall ring filler in the tower body, and filler top is provided with shower and nozzle 2; Liquid drop separator is positioned at the top on said absorption tower; Liquid drop separator inside is uniformly distributed with by deflection plate grid 3; Deflection plate grid corner and top are provided with the dentation liquid opposite with the airflow direction flange that blocks water, and prevent the out-of-date drop that attaches on deflection plate of taking away of air communication.Wherein, the structure of deflection plate grid 3 is as shown in Figure 2, and Fig. 3 is the generalized section along the B-B direction of accompanying drawing 2, and the set dentation liquid in deflection plate grid 3 corners and the top flange that blocks water shows in accompanying drawing 3 to some extent.
Flue gas after absorbing through top spray water, under the swabbing action of blower fan negative pressure, the flue gas (account for flue gas cumulative volume 60%) that has a large amount of steam is through this top, novel absorption tower drop separation the time; Through the baffling flase floor time; 90 ° turning to can take place in air-flow, and the saturated drop in this process in the flue gas can be attached on the flase floor, accumulates in the dentation liquid obscures part; Splash in the absorption tower subsequently, thereby reach gas-liquid separation effect.The drop that is stopped has absorbed the HCl composition in the flue gas, has reduced the content of HCl in the flue gas, has alleviated the corrosion of acid smoke waste gas to blower fan, has reduced the pollutant emission in the tail gas.
The preferred embodiment that the above is merely the utility model is not the practical range that is used for limiting the utility model; If do not break away from the spirit and the scope of the utility model, the utility model is made amendment or is equal to replacement, all should be encompassed in the middle of the protection domain of the utility model claim.
Claims (3)
1. the acid regeneration absorption tower with the drop separation function is characterized in that, comprises liquid drop separator, and wherein, said liquid drop separator is positioned at the top on said absorption tower, and the inside of said liquid drop separator evenly is furnished with the deflection plate grid.
