Abstract
The utility model discloses a hydrogen chloride tail gas cleanup unit, including reation kettle, still include hydrogen chloride absorption tower, first packing layer, aspirator, first shower head, diluted acid jar, the reation kettle top is provided with the aspirator, and the aspirator is connected with hydrogen chloride absorption tower bottom through the fan, hydrogen chloride absorption tower upper portion is provided with first shower head, be provided with first packing layer under the first shower head, first packing layer bottom is connected with the diluted acid jar. The utility model provides a pair of hydrogen chloride tail gas cleanup unit has reduced equipment, reduces maintenance cost and running cost, the hydrogen chloride clearance has been improved to hydrochloric acid solution can be obtained, economic value is increased.
Description
Technical field
The utility model relates to a kind of hydrogen chloride tail gas purifier, belongs to technical field of waste gas treatment.
Background technology
Hydrogen chloride, be a kind of colourless non-combustible gas, have polar stimulation smell, proportion is greater than air, meets malaria and produces white mist, very easily water-soluble, generates hydrochloric acid.There is severe corrosive, can react with various metals and produce hydrogen, explosive mixture can be formed with air, meet cyanide and produce hypertoxic hydrogen cyanide.
Absorption process normally uses alkali liquor absorption, both consumes alkali lye like this, can generate again very unmanageable brine waste, cause dual waste.
Utility model content
Object: in order to overcome the deficiencies in the prior art, the utility model provides a kind of hydrogen chloride tail gas purifier.
Technical scheme: for solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of hydrogen chloride tail gas purifier, comprise reactor, also comprise hydrogen chloride absorption tower, the first packing layer, draught hood, the first spray head, diluted acid tank, described reactor top is provided with draught hood, and draught hood is connected with hydrogen chloride absorption tower bottom by blower fan; Described hydrogen chloride absorption tower top is provided with the first spray head, and described first spray head is arranged with the first packing layer, is connected bottom described first packing layer with diluted acid tank.
Also comprise the second spray head, the second packing layer, concentrated acid tank, be provided with the second spray head in the middle part of described hydrogen chloride absorption tower, described second spray head is arranged with the second packing layer; Described diluted acid tank is connected with concentrated acid tank by circulating pump, and described concentrated acid tank is connected with the second spray head by circulating pump, is connected bottom described second packing layer with concentrated acid tank.
Described hydrogen chloride absorption tower tower diameter is set to 900mm.
The height of described first packing layer, the second packing layer is all set to 6000mm.
Preferably, described first packing layer, the second packing layer all adopt ceramic wafer ripple packing.
Preferably, described blower fan adopts centrifugal blower.
Beneficial effect: a kind of hydrogen chloride tail gas purifier that the utility model provides, decreases equipment, reduces maintenance cost and operating cost; Improve hydrogen chloride clearance, and can hydrochloric acid solution be obtained, increase economic worth.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1, a kind of hydrogen chloride tail gas purifier, reactor 1 top is provided with draught hood 2, and the hydrogen chloride produced by reactor 1 is introduced bottom hydrogen chloride absorption tower 4 by blower fan 3; Running water is sprayed into hydrogen chloride absorption tower 4, first spray head 5 from the first spray head 5 to be sprayed on the first packing layer 6 by running water, after acting on mutually, flows in diluted acid tank 7 after being dissolved as watery hydrochloric acid with hydrogen chloride; Watery hydrochloric acid in diluted acid tank 7 flows into concentrated acid tank 9 through circulating pump 8 again; Concentrated acid tank 9 sprays 10 by circulating pump 8 on the second packing layer 11 through the second spray head, and watery hydrochloric acid acts on mutually with hydrogen chloride again, is dissolved as concentrated hydrochloric acid and collects in concentrated acid tank 9.
The above is only preferred embodiment of the present utility model; be noted that for those skilled in the art; under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
