Abstract
The utility model discloses acid mist recovering and purifying equipment, and aims to provide acid mist recovering and purifying equipment with sufficient purification, high recovery rate, small equipment load, low running cost and qualified emission. The acid mist recovering and purifying equipment comprises an acid cleaning device (1), a mist collector (2), a purifying column (3) and a mist discharge fan (4), wherein the acid cleaning device (1) is connected with a condenser (5), a liquid drop separator (6), the purifying column (3) and the mist discharge fan (4) in sequence through the mist collector (2); the liquid drop separator (6) is connected with the acid cleaning device (1) through an acid storage tank (7); and the condenser (5) is a mixing condenser or a tubular condenser or a spraying condenser or a plate type condenser. The utility model is suitable for the acid mist recovering and purifying treatment of industrial acid cleaning workshops.
Description
Technical field
The utility model relates to a kind of acid mist reclaiming clean equipment, and more particularly, it relates to a kind of industrial acid mist reclaiming clean equipment.
Background technology
In industrial production, need carry out pickling with hydrochloric acid, hydrochloric acid produces acid mist through heating when circulating, and acid mist is made up of HCL gas and water vapour.As shown in Figure 2, after acid mist enters purifying column 3 washing absorptions through mist collector 2 usually, enter chimney 9 by fog discharge blower fan 4 and be discharged into atmosphere, the acid solution that the absorption acid mist forms is discharged into waste water processing station 8.The shortcoming that former design exists is: washing absorbs the shower water of acid mist, needs to throw in Na (OH)
2Measure excessive; Washing absorbs the shower water of HCL and throws in Na (OH)
2After still be stronger acidity, acid-bearing wastewater is discharged to waste water processing station 8 also needs secondary to throw in Na (OH)
2Neutralisation treatment, original design has not only been wasted Acidwash solution but also strengthened cost for wastewater treatment; Fog HCL content overproof through purifying column 3 dischargings.Its weak point is that acid mist purifies equipment acid consumption height, operating cost is high, and discharging is not up to standard.
The utility model content
The purpose of this utility model is to overcome deficiency of the prior art, provides a kind of and purifies fully, the rate of recovery is high, machine utilization is little, operating cost is low, the acid mist reclaiming clean of emission compliance equipment.
In order to solve the technical problem of above-mentioned existence, the utility model adopts following technical proposals: comprise acid dip pickle 1, mist collector 2, purifying column 3, fog discharge blower fan 4; Described acid dip pickle 1 is connected with condenser 5, liquid drop separator 6, purifying column 3, fog discharge blower fan 4 successively by mist collector 2; Described liquid drop separator 6 is connected with acid dip pickle 1 by acid storage tank 7.
Described condenser 5 is mixing condenser or shell and tube condenser or spraying condenser or plate-type condenser.
The utility model acid mist reclaiming clean equipment has following beneficial effect compared with prior art:
Acid mist fully purifies; By recovery to HCL gas, realized recovery condensation acid solution, reduce hydrochloric acid and consumed 12%; Alleviate the load of purifying column, thereby reduced 80%Na (OH)
2Injected volume; The fog that is discharged into atmosphere has reached discharging standards.
Description of drawings
Fig. 1 is new acid mist reclaiming clean equipment schematic diagram;
Fig. 2 is former acid mist reclaiming clean equipment schematic diagram.
The specific embodiment
As shown in Figure 1, acid dip pickle 1 is connected with mist collector 2, and described mist collector 2 is connected with liquid drop separator 6 by condenser 5; Described condenser 5 can be mixing condenser or shell and tube condenser or spraying condenser or plate-type condenser; Described liquid drop separator 6 is connected with purifying column 3, and described liquid drop separator 6 is connected with acid dip pickle 1 by acid storage tank 7; Described purifying column 3 is connected with chimney 9 by fog discharge blower fan 4, and is connected with waste water processing station 8.
Hydrochloric acid circulates through heating and produces acid mist in acid cleaning process, is made up of HCL gas and water vapour.Acid mist in the acid dip pickle 1 enters mist collector 2, because acid mist low temperature meeting condensation, the acid mist in the mist collector 2 enters condenser 5, makes most of acid mist be condensed into liquid acids.This liquid acids enters liquid drop separator 6, carries out gas-liquid separation by liquid drop separator 6.The acid solution that liquid drop separator 6 separates enters acid storage tank 7 and stores, and the acid solution of described acid storage tank 7 flows back to acid dip pickle 1 again and is used for complex acid, by the recovery to HCL gas, has realized recovery condensation acid solution, has reduced hydrochloric acid and has consumed 12%.Residue fraction acid mist enters purifying column 3 after the drop separation, has alleviated the load of purifying column 3 significantly, thereby has reduced 80%Na (OH)
2Injected volume.By reclaiming acid solution, make to purify fully.In described purifying column 3 packing layer is arranged, acid mist is absorbed purification by packing layer and the shower water generation neutralization reaction that is alkalescence, and residue fog enters chimney 9 by fog discharge blower fan 4 and is discharged into atmosphere, makes the fog that is discharged into atmosphere reach national standard.The shower water that absorbs acid mist formation is discharged into waste water processing station 8 and handles.
The above only is an example of the present utility model, and simultaneously example does not limit the utility model, and is all within spirit of the present utility model and principle, any modification of being done, is equal to replacements, improvement etc., all should be included within practical protection domain.
Claims (2)
