Abstract
The utility model discloses a device for processing acid mist. The device comprises a pickling device, a mist collector, a purification tower and a mist exhaust fan, wherein the pickling device is successively connected with a condenser, a liquid drop separator, the purification tower and the mist exhaust fan through the mist collector, and the liquid drop separator is connected with the pickling device through an acid storage tank. Compared with the prior art, the device for processing acid mist disclosed by the utility model has the beneficial effects that the acid mist is fully purified, the recovery of condensed acid liquor is achieved by the recovery of HCL (hydrochloride) gas, the consumption of hydrochloric acid is reduced, the load of the device for processing acid mist is also reduced, so as to reduce the feeding amount of sodium hydroxide, and the mist discharged into the atmosphere achieves the national discharge standard.
Description
Technical field
The utility model relates to a kind of acid mist treating apparatus.
Background technology
In commercial production, need carry out pickling with hydrochloric acid, hydrochloric acid produces acid mist through heating when circulating, and the weak point of prior art is that acid mist purification equipment acid consumption is high, operating cost is high, and discharges not up to standard.
The utility model content
The purpose of the 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 treating apparatus of emission compliance.
In order to solve the technical problem of above-mentioned existence, the utility model adopts following technical proposals:
A kind of acid mist treating apparatus, comprise acid dip pickle, mist collector, purifying column, fog discharge blower fan; Said acid dip pickle is connected with condenser, liquid drop separator, purifying column, fog discharge blower fan through mist collector successively; Said liquid drop separator is connected with acid dip pickle through acid storage tank.
Preferably, said condenser is mixing condenser or shell and tube condenser or spraying condenser or plate-type condenser.
The utility model acid mist treating apparatus has following beneficial effect compared with prior art: acid mist fully purifies; Through recovery to HCL gas, realized recovery condensation acid solution, reduced hydrochloric acid consumption; Alleviated the load of acid mist treating apparatus, thereby reduced the NaOH injected volume, the fog that is discharged into atmosphere has reached discharging standards.
Description of drawings
Fig. 1 is new acid mist treating apparatus sketch map.
The specific embodiment
As shown in Figure 1, acid dip pickle 1 is connected with mist collector 2, and said mist collector 2 is connected with liquid drop separator 6 through condenser 5; Said condenser 5 can be mixing condenser or shell and tube condenser or spraying condenser or plate-type condenser; Said liquid drop separator 6 is connected with purifying column 3, and said liquid drop separator 6 is connected with acid dip pickle 1 through acid storage tank 7; Said purifying column 3 is connected with chimney 9 through 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 gets into mist collector 2, because acid mist low temperature meeting condensation, the acid mist in the mist collector 2 gets into condenser 5, makes most of acid mist be condensed into liquid acids.This liquid acids gets into liquid drop separator 6, carries out gas-liquid separation through liquid drop separator 6.The acid solution that liquid drop separator 6 separates gets into acid storage tank 7 and stores, and the acid solution of said acid storage tank 7 flows back to acid dip pickle 1 again and is used for complex acid, through the recovery to HCL gas, has realized recovery condensation acid solution, has reduced hydrochloric acid consumption.Residue fraction acid mist gets into purifying column 3 after the drop separation, has alleviated the load of purifying column 3 significantly, thereby has reduced the injected volume of NaOH.Through reclaiming acid solution, make to purify fully.In said purifying column 3, packing layer is arranged, acid mist is absorbed purification through packing layer and the shower water generation neutralization reaction that is alkalescence, and residue fog gets into chimney 9 through 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.
Those of ordinary skill in the art will be appreciated that; Above embodiment is used for explaining the utility model; And be not the qualification that is used as the utility model; As long as in the connotation scope of the utility model, all will drop in claims scope of the utility model variation, the modification of the above embodiment.
Claims (2)
1. acid mist treating apparatus; Comprise acid dip pickle, mist collector, purifying column, fog discharge blower fan; It is characterized in that said acid dip pickle is connected with condenser, liquid drop separator, purifying column, fog discharge blower fan through mist collector successively, said drop separation is connected with acid dip pickle through acid storage tank.
2. acid mist treating apparatus according to claim 1 is characterized in that, said condenser is mixing condenser or shell and tube condenser or spraying condenser or plate-type condenser.
