Description
Technical field
The utility model relates to a kind of absorption plant, specifically a kind of trifluorotrichloroethane chlorine absorption unit, belonging to
Construction equipment technical field.
Background technique
Application publication number is that the patent document of CN102617273A discloses a kind of high temperature gas phase greening method production trifluoro three
Chloroethanes, this method carry out high temperature gas phase chlorination reaction using trifluoroethane and chlorine, then by absorption by Hydrochloric Acid system, lye
Gas and liquid are isolated with system and liquefaction system, becomes recycling gas after gas dry and participates in reaction, liquid is grasped by rectifying
Make, produces trifluorotrichloroethane.
In process of production, chlorine gas absorption tower is entered after material is reacted, but material can not be complete before entering absorption tower
Chlorine component therein is removed, causes to contain chlorine in material, the chlorine being mingled in material can not be recycled in rear workshop section,
It can only empty or neutralize, chlorine is caused to waste, unit consumption increases.
Utility model content
The purpose of the utility model is to provide a kind of trifluorotrichloroethane chlorine absorption unit, reaches and absorb three chloroethene of trifluoro
The purpose of extra chlorine in alkane.
In order to reach above-mentioned technical purpose, the technical solution of the utility model is:
A kind of trifluorotrichloroethane chlorine absorption unit, including chlorine gas absorption tower, the chlorine gas absorption tower outlet at bottom are logical
It crosses outlet line to connect with circulating pump, the chlorine gas absorption tower refluxing opening is connect by reflux pipeline with circulating pump, the reflux
Waste liquid outlet pipeline is connected on pipeline；There is material inlet, the material inlet and material are fed on the chlorine gas absorption tower
Pipeline connects, and also has tetrachloro-ethylene import on the chlorine gas absorption tower, and the tetrachloro-ethylene import and tetrachloro-ethylene pipeline connect
It connects, the chlorine absorption top of tower is provided with material outlet.
In order to ensure the safety of circulation line, relief valve is provided on the outlet line.
In order to measure the liquid level in chlorine gas absorption tower, liquidometer is provided on the chlorine gas absorption tower.
In order to control the flowing of waste liquid, regulating valve is provided on the waste liquid outlet pipeline.
The utility model makes material that can fully absorb chlorine, utilize in absorption tower by addition solvent, reduces chlorine
Gas entrainment, to reduce unit consumption.
Detailed description of the invention
Fig. 1 is utility model diagram.
Specific embodiment
Utility model will be further described in detail below with reference to the attached drawings and specific embodiments.
As shown in Figure 1, a kind of trifluorotrichloroethane chlorine absorption unit, including chlorine gas absorption tower 5, the chlorine gas absorption tower
There is material inlet, the material inlet is connect with material feeding line 1, also has four chloroethenes on the chlorine gas absorption tower 5 on 5
Alkene import, the tetrachloro-ethylene import are connect with tetrachloro-ethylene pipeline 2.Material outlet is provided at the top of the chlorine gas absorption tower 5
6.In order to measure the liquid level in chlorine gas absorption tower 5, liquidometer is provided on the chlorine gas absorption tower 5.
5 outlet at bottom of chlorine gas absorption tower is connect by outlet line with circulating pump 3, in order to ensure the peace of circulation line
Entirely, relief valve is provided on the outlet line.
5 refluxing opening of chlorine gas absorption tower is connect by reflux pipeline with circulating pump 3, is connected on the reflux pipeline useless
Liquid outlet line 4.In order to control the flowing of waste liquid, regulating valve is provided on the waste liquid outlet pipeline 4.
In use, a certain amount of tetrachloro-ethylene is first added in chlorine gas absorption tower 5, opens circulating pump 6 and recycle, after circulation is reached,
Material continuously enters in chlorine gas absorption tower 5, and tetrachloro-ethylene equally starts quantitative continuous feed, is arranged at the top of chlorine gas absorption tower 5
There is material outlet opening, to form continuous feeding and discharging balance.
Above-described embodiment does not limit the utility model in any way, all by the way of equivalent substitution or equivalent transformation
The technical solution of acquisition is all fallen in the protection scope of the utility model.
