Description
Technical field
It the utility model is related to one kind and remove bromine device, bromine device is removed more particularly to a kind of high-purity methane chloride.
Background technology
Since 2011, domestic methane chloride production capacity is expanded rapidly, but product quality is uneven.At home,
Most of chloromethanes is all widely used as solvent, and their dissolubility is strong, and with non-ignitable（In addition to CH3Cl）The advantages of.In order to carry
The quality of high methane chloride, as high-quality downstream product raw material, it is necessary to ensure that the production of high-purity chlorine could improve methane chlorine
Compound product quality.
In the utility model patent of Patent No. 201520197374.7, it is noted that one kind prepares high-purity methane chloride use
Crude salt removes bromine equipment, including acidifying stills for air blowing, pumping system, heater, vacuum remove bromine tower, water treatment facilities, its pumping system
By pipeline and vacuum pump group into, have opening and connecting pipe at the top of acidifying stills for air blowing, its be acidified between stills for air blowing and heater with
Pipeline connects and vavuum pump is housed, its heater also by pipeline with vacuum except bromine tower is connected, its vacuum is provided with except bromine tower top
Bromine gas recovery port, the pipeline equipped with the first centrifugal pump is connected with after bromine gas recovery port, its vacuum is except bromine tower bottom is by being connected with the 3rd
The pipeline of vavuum pump is connected with water treatment facilities.The utility model is directly processed to mixed material, though it is more traditional
Unit efficiency is improved, but still has room for promotion；It is acidified before Feedstock treating simultaneously, therefore removes bromine
Also need to carry out subsequent treatment to product after end.
Utility model content
In order to overcome the above-mentioned deficiencies of the prior art, the utility model provide a kind of high-purity methane chloride except bromine fill
Put.
To reach above-mentioned purpose, technical scheme is used by the utility model solves its technical problem：
A kind of high-purity methane chloride removes bromine device, including be sequentially connected electrolytic cell, Chlorine Scrubber, heater and
Dechlorinator；There is a dog-house on the electrolytic cell；There is a sieve plate inside the dechlorinator, the dechlorinator end connects respectively
One tail gas recycle tank and finished product collection device；There is a vavuum pump, the finished product is received between the tail gas recycle tank and dechlorinator
There is the first centrifugal pump between acquisition means and dechlorinator.
Further, the heating-up temperature in the heater is 70~90 DEG C.
Further, there is the second centrifugal pump between the heater and dechlorinator.
Further, a heat-insulation layer is provided with outside the electrolytic cell.
Due to the utilization of above-mentioned technical proposal, the utility model has following beneficial effect compared with prior art：
（1）The utility model utilizes existing forms of the bromine in chlorine water, and bromine is separated from chlorine water, separation effect
Fruit is good, and energy resource consumption is low；Directly chlorine is electrolysed out by electrolytic cell simultaneously, subsequently directly chlorine and bromine separated, point
From efficiency high.
（2）There is the second centrifugal pump between heater and dechlorinator, be delivered to high temperature chlorine water by the second centrifugal pump de-
Chlorine top of tower spray, to increase specific surface area, is being sprayed the bromine being dissolved in high temperature chlorine water by vavuum pump through sieve plate to tower reactor
Separated during leaching, bromine high purity chlorine is removed to reach.
（3）A heat-insulation layer is provided with outside electrolytic cell, to realize the safety and stability of electrolytic cell and efficient purpose.

Embodiment
With reference to specific embodiment, content of the present utility model is described in further detail：
As shown in figure 1, a kind of high-purity methane chloride removes bromine device, including electrolytic cell 1, the chlorine washing being sequentially connected
Tower 3, heater 4 and dechlorinator 6；There is a dog-house 2 on electrolytic cell 1；Heating-up temperature in heater 4 is 70~90 DEG C, with
There is the second centrifugal pump 5 between dechlorinator 6；The inside of dechlorinator 6 has a sieve plate 7, and the end of dechlorinator 6 connects a tail gas respectively
Recycling can 9 and finished product collection device 11；There is a vavuum pump 8, finished product collection device 11 between tail gas recycle tank 9 and dechlorinator 6
There is the first centrifugal pump 10 between dechlorinator 6.
During work, raw material goes out chlorine in the Inner electrolysis of electrolytic cell 1, and the chlorine for then being electrolysed out enters Chlorine Scrubber 3, this
Bromine a small amount of Shi Huiyou is dissolved in chlorine water, and chlorine water enters heater heat temperature raising afterwards, then by the second centrifugal pump 5 by height
Warm chlorine water is delivered to the top spray of dechlorinator 6 through sieve plate 7 to tower reactor to increase specific surface area, and height will be dissolved in by vavuum pump 8
Bromine in warm chlorine water is separated during spray, and bromine high purity chlorine is removed to reach.
For above-described embodiment only to illustrate technical concepts and features of the present utility model, its object is to allow be familiar with technique
Personage can understand content of the present utility model and be carried out, the scope of protection of the utility model can not be limited with this,
All equivalent change or modifications made according to the utility model Spirit Essence, should all cover in the scope of protection of the utility model
