Description

A kind of roasting method acid regeneration acid mist reclaiming clean device being provided with membrance-type absorber and condenser
Technical field
The utility model relates to a kind of roasting method acid regeneration acid mist reclaiming clean device being provided with membrance-type absorber and condenser.
Background technology
Not only current domestic roasting method acid regeneration has nearly hundred, and its acid mist purifying technique is all first adopt absorption tower to absorb acid mist, remains acid mist afterwards and after scrubbing tower washing, purifying, is discharged into air again, wastes the energy simultaneously but also cause environmental pollution.
Utility model content
For above-mentioned defect and the problem of prior art, the utility model object there is provided and a kind ofly can utilize the HCL gas of high temperature and the feature of steam cryogenic condensation, before entering scrubbing tower, first make most acid mist be condensed into liquid state and collect, then remaining fraction acid mist is finally discharged into the acid regeneration acid mist reclaiming clean device of air through scrubbing tower washing absorption.
In order to achieve the above object, the utility model provides following technical scheme:
A kind of roasting method acid regeneration acid mist reclaiming clean device being provided with membrance-type absorber and condenser, comprise absorption tower, scrubbing tower, membrance-type absorber, condenser, liquid drop separator, acid fog blower fan, collecting tank and conveyance conduit, described absorption tower is provided with outlet, outlet is connected with membrance-type absorber by pipeline, described membrance-type absorber is connected with one end of condenser by pipeline, the described condenser other end is connected with liquid drop separator one end, the liquid drop separator other end is connected with acid fog blower fan entrance by pipeline, acid fog blower fan outlet is connected with scrubbing tower, the lower end of described liquid drop separator is provided with outlet, outlet is connected with collecting tank.
Further, described mode absorbent device also have the first cooling water inlet and the first coolant outlet.
Further, the lower end of described mode absorbent device is also provided with sampling outlet, and described sampling outlet passes through Valve controlling.
Further, condenser is provided with the second cooling water inlet and the second coolant outlet.
The beneficial effects of the utility model are, because acid mist produces in the process of roasting in acid solution, so utilize the feature of acid mist cryogenic condensation, first through the further cooling and absorbing of membrance-type absorber before entering scrubbing tower, cool through condenser more afterwards, its temperature is reduced, by gaseous state liquefy, most of acid mist is condensed into liquid state and collects, last remaining fraction acid mist is discharged into air after scrubbing tower washing absorption, this device not only achieves the recycling to acid mist, save production cost, also greatly reduce the load of scrubbing tower simultaneously, the acid mist being discharged into air is made to reach national requirements completely.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the structural representation being provided with the roasting method acid regeneration acid mist reclaiming clean device of membrance-type absorber and condenser of the present utility model.
