Description
Technical field
The utility model belongs to chlorinated paraffin preparing technical field, that is, is related to a kind of hydrogen chloride as by product of chlorinated paraffin production that improves and inhales
Yield device.
Background technology
Problems be present in the production process of chlorinated paraffin：First, chlorinated paraffin product is at the initial stage for feeding intake production,
Reaction temperature is low to cause chlorine absorption incomplete, and a small amount of chlorine is contained in by-product hydrogen chloride, is unfavorable for it and is used to give birth to as raw material
Produce other products.Second, the absorption to tail gas hydrogen chloride is completed by spraying alkali lye and water in a reservoir in the prior art, this
The method that the mode that kind is neutralized with alkali acid absorbs removal chlorinated paraffin by-product tail gas hydrogen chloride is the significant wastage to resource.
And hydrogen chloride is a kind of extremely wide gas of application, the hydrometallurgy of rare metal can be applied to, for all
Such as be polymerized polyvinyl chloride organic synthesis, intermetallic composite coating, prepare the food industry such as soy sauce and monosodium glutamate and medicine production etc.
Field.But the synthesis of hydrogen chloride is to be carried out by hydrogen and chlorine in special synthetic furnace, operation difficulty be present greatly and danger is
The defects of number is high, its production cost is high.
So it is existing remove chlorinated paraffin by-product tail gas hydrogen chloride technical costs is not only high but also waste of resource, be unfavorable for ring
Protect.
Utility model content
In order to solve above-mentioned prior art problem, the utility model aims to provide one kind can be abundant by Chlorcosane tail gas
Absorb the device of generation hydrochloric acid, i.e., it is a kind of to improve hydrogen chloride as by product of chlorinated paraffin production absorptivity device.
To achieve these goals, technical scheme is as follows used by the utility model：
One kind improves hydrogen chloride as by product of chlorinated paraffin production absorptivity device, including gas absorption tank, the gas absorption tank
Left side top is connected with blast pipe, and left bottom is connected with air inlet pipe, in addition to field word jet net, circulation pipe, discharging tube, heating
Alembic, the gas absorption tank are made up of the first absorption chamber and the second absorption chamber, and the absorption chamber is built with saturated sodium-chloride
Liquid, liquid level inhale the top of first absorption chamber and second with leaving space, the circulation pipe at the top of the absorption chamber
The bottom connection of room is received, the chlorine containing remaining hydrogen chloride gas is recycled to the second absorption chamber from the first absorption chamber；The field
Word jet net is separately mounted in the saturated sodium-chloride liquid of the absorption chamber, one in first absorption chamber with it is described enter
Tracheae, which is connected, sprays the hydrogen chloride gas containing chlorine, and the ejection that is connected in second absorption chamber with circulation pipe is containing residual
The chlorine of remaining hydrogen chloride gas, the discharging tube are separately mounted to the bottom of first and second absorption chamber, will contain chlorination
The liquid of hydrogen and sodium chloride is discharged into the heating alembic.
Further preferred scheme is that the field word jet is equipped with nozzle on the net.
The utility model improve chlorinated paraffin by-product tail gas hydrogen chloride absorptivity simultaneously, it is not only cost-effective but reduce money
Source wastes, beneficial to environmental protection.

Embodiment
The technical solution of the utility model is further detailed below in conjunction with specific embodiment, but this practicality is new
The protection domain of type is not limited to that those skilled in the art are worked with non-creativeness changes its structure, should belong to this
The protection domain of utility model.
Pass through air inlet pipe 6 from the chlorinated paraffin by-product tail gas hydrogen chloride containing chlorine of production chlorinated paraffin reactor discharge
Sprayed into by field word jet net 2 in the first reative cell in 51 saturated sodium-chloride liquid, saturated sodium-chloride liquid fully absorbs chlorine
Change mixing liquid of the hydrogen generation containing sodium chloride and hydrochloric acid.
Unabsorbed chlorine and the remaining hydrogen chloride gas not being fully absorbed enter the second absorption chamber by circulation pipe 4
52.Remaining hydrogen chloride gas is secondary by the saturated sodium-chloride liquid in the second absorption chamber 52 by the sprinkling of field word jet net 2
Absorb.
Only secondary profit in the reactor of production chlorinated paraffin is discharged or be discharged into again to the gas containing chlorine by blast pipe 1
With.
The mixing liquid of sodium chloride and hydrochloric acid in the first absorption chamber 51 and the second absorption chamber 52 is flowed into by discharging tube 8
Heat in alembic 7, by heating by sodium chloride and HCl separation, so as to obtain sodium chloride crystal and hydrochloric acid.
In preferred scheme, by installing nozzle 3 on field word jet net 2, the scattered penetrating saturated sodium-chloride of gas can be made
In liquid, beneficial to fully absorbing.
