Description
Technical field
The utility model relates to a kind of cold-rolling pickling line acid mist and reclaims circulation without tapping equipment.
Background technology
Current China pickling lines has hundreds of bar, but in the sector, no matter is continuous pickling or plug-type pickling, and its acid cleaning process is all first acid solution is heated to technological temperature to carry out the pickling of circular flow dynamic formula by circulating pump.In this course, a large amount of HCL gas will evaporate along with steam thus produce a large amount of acid mists from hydrochloric acid.The loss of hydrochloric acid and acid mist purifying process also just become the amount hang-up of puzzlement pickling producer.
Present most of production unit is taked to use the mode of acid mist purifying tower to carry out washing absorption to acid mist, and the acid solution after absorption is directly disposed to water treatment station, so not only wastes acid solution but also environment is produced to the negative effect of beating very much, each unit cost production is increased.Simultaneously, acid mist is difficult to reach discharging standards after carrying out washing absorption by means of only acid mist purifying tower, this makes again each production unit increase pollution to environment, also there is minority production unit to adopt and acid mist condenser and liquid drop separator are installed before acid mist purifying tower, the condensation making acid mist carry out the initial stage is reclaimed, purified by acid mist purifying tower more afterwards, via smoke stack emission to air, the acid solution simultaneously in acid mist purifying tower is disposed to water treatment station again and processes.
Utility model content
For above-mentioned defect and the problem of prior art, the utility model object there is provided a kind of can realization and has saved production cost to the recovery of HCL gas, and the residual gas after recycling is directly transmitted back in cell body, without the need to airborne release, without the need to re-using acid mist purifying tower and chimney, the cold-rolling pickling line acid mist that can not produce again containing the waste water of acid reclaims circulation without tapping equipment.
In order to achieve the above object, the utility model provides following technical scheme:
A kind of cold-rolling pickling line acid mist reclaims circulation without tapping equipment, comprise circulating tank, the below of described circulating tank is provided with descaling bath, descaling bath is connected with circulating tank by pipeline, the below of described descaling bath is connected with acid fog blower fan by multiple pipeline, described acid fog blower fan is connected with one end of the first liquid drop separator, the other end of described first liquid drop separator is connected with first condenser one end, the other end of described first condenser is connected with the second liquid drop separator by pipeline, described second liquid drop separator is connected with the second condenser, described second condenser is connected with rinse bath, described rinse bath is connected with descaling bath by pipeline.
Further, described first liquid drop separator and the second liquid drop separator are equipped with liquid-inlet and liquid outlet.
Further, described first condenser and the second condenser are equipped with import and outlet.
The beneficial effects of the utility model are, whole flow process of the present utility model is the cyclic process of a gas, high-temperature gas is cooled to volume-diminished after cryogenic gas and liquid, but the air quantity of blower fan is constant, can continue in cell body to form slight negative pressure, enter in cell body from ambient inlet air, to ensure circulation, so there will not be the phenomenon of acid fog outflow in cell body.
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 that cold-rolling pickling line acid mist of the present utility model reclaims the structural representation of circulation without tapping equipment.
Detailed description of the invention
Below in conjunction with accompanying drawing of the present utility model, be clearly and completely described the technical solution of the utility model, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1, a kind of cold-rolling pickling line acid mist disclosed in the utility model reclaims circulation without tapping equipment, comprise circulating tank 1, the below of described circulating tank 1 is provided with descaling bath 2, descaling bath 2 is connected with circulating tank 1 by pipeline, the below of described descaling bath 2 is connected with acid fog blower fan 3 by multiple pipeline, described acid fog blower fan 3 is connected with one end of the first liquid drop separator 4, the other end of described first liquid drop separator 4 is connected with first condenser 5 one end, the other end of described first condenser 5 is connected with the second liquid drop separator 6 by pipeline, described second liquid drop separator 6 is connected with the second condenser 7, described second condenser 7 is connected with rinse bath 8, described rinse bath 8 is connected with descaling bath 2 by pipeline.
Preferred technical scheme, described first liquid drop separator and the second liquid drop separator are equipped with liquid-inlet and liquid outlet.
Preferred technical scheme, described first condenser and the second condenser are equipped with import and outlet.
The utility model oh technological principle is:
Utilize the HCL gas of high temperature and the feature of steam cryogenic condensation, first make most acid mist be condensed into liquid state and collect before entering purifying column, then remaining oh fraction acid mist is finally discharged into air through acid mist purifying tower washing absorption.
The above; be only detailed description of the invention of the present utility model; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; change can be expected easily or replace, all should be encompassed within protection domain of the present utility model.Therefore, protection domain of the present utility model should described be as the criterion with the protection domain of claim.
