Although during solve the problems, such as that chlorine waste is larger, in chlorination reaction process produce hydrogen chloride gas can not have
Quick discharge system is imitated, so as to influence chlorination reaction velocity, independent tower chlorination reaction, will also result in two in course of reaction in addition
Chloride is higher.
Utility model content
The utility model provides a kind of continuous chlorination reaction unit, and the device chlorination reaction efficiency high can be by every grade
Chlorine total overall reaction in reactor is completed, and saves chlorine consumption, and because material is back to back, does not have material back-mixing to show
As product yield can be improved.
The concrete technical scheme that the utility model is used is as follows：
A kind of continuous chlorination reaction unit, including thtee-stage shiplock chlorination reactor, every grade of chlorination reactor is by connecting
Chlorination reaction tower, gas-liquid separator, cooler and circulating pump composition；
Air inlet branch road is passed through on pipeline between every grade of circulating pump and chlorination reaction tower of chlorination reactor；
Charging branch road is passed through on pipeline between every grade of circulating pump and cooler of chlorination reactor；
Between adjacent two-stage chlorination reactor, the partial material of the gas-liquid separator output of upper level chlorination reactor is led to
Corresponding charging branch road is crossed to enter in next stage chlorination reactor；
Gas-liquid separator in the chlorination reactor of afterbody is connected with material storage tank by the branch road that discharges.
In the utility model, material is circulated in every grade of reactor of series connection, and material is circulated in the first order before chlorination
Added before pump, chlorine is pressed different proportion and entered from every grade of chlorination reaction tower bottom respectively, and chlorination reaction is entered after mixing with material
Chlorination reaction is carried out in tower, material and the hydrogen chloride per stage reactor carry out vapor-liquid separation into after in gas-liquid separator, produce
Hydrogen chloride gas enter exhaust treatment system, and the material that unreacted is completed is partly into before next stage circulating pump and chlorine
Proceed chlorination reaction, a part continues cycling through reaction after lowering the temperature through subcooler into this grade of circulating pump, from third level vapour
The chloride material reaction that liquid/gas separator overflows is completed, feeding material storage tank storage.
As preferred, the exhaust branch same tail gas absorption of access of the gas-liquid separator connection in every grade of chlorination reactor
Pipeline, is easy to collect and absorb the chlorine that chlorination reactors at different levels are isolated.
It is dividing wall type cooler or coil pipe type cooler as preferred, described cooler.
As control valve is provided with preferred, described air inlet branch road, for controlling to enter in chlorination reactors at different levels
Chlorine fraction.
The utility model simple structure, is easy to operate and controls, and further improves chlorination reaction efficiency and yield, using even
Continuous charging and continuous discharge mode, so as to improve chlorination reaction efficiency and the corresponding yield of product.
Brief description of the drawings
Fig. 1 is continuous chlorination reaction unit schematic diagram in the utility model.
Specific embodiment
Continuous chlorination reaction unit as shown in Figure 1, including thtee-stage shiplock chlorination reactor, every grade of chlorination reactor by
Chlorination reaction tower 1, gas-liquid separator 2, cooler 3 and circulating pump 4 are connected in sequence.
In the present embodiment, it is provided with the pipeline between every grade of circulating pump of chlorination reactor 4 and chlorination reaction tower 1 and is passed through
The air inlet branch road 5 of chlorine, connection is passed through material on the pipeline between every grade of circulating pump of chlorination reactor 4 and cooler 3
Charging branch road 6.Between adjacent two-stage chlorination reactor, the part thing of the output of gas-liquid separator 2 of upper level chlorination reactor
Material is entered in next stage chlorination reactor by corresponding charging branch road 6；Gas-liquid separation in the chlorination reactor of afterbody
Device 2 is connected with material storage tank 8 by the branch road 7 that discharges, for storing the chloride material that reaction is completed.
The exhaust branch 9 of the connection of gas-liquid separator 2 in every grade of chlorination reactor accesses same tail gas absorption pipeline 10, send
Enter tail gas absorbing system to be reclaimed.In the present embodiment, control valve is installed in air inlet branch road 5, for controlling to enter chlorine at different levels
Change the chlorine fraction in reactor.
When continuous chlorination reaction unit in the present embodiment works, be full of for each stage reactor first by chlorination reaction raw material,
Do not discharged temporarily full of rear, advanced row intermittent reaction after every grade of intermittent chlorination reaction is reached home, is ready for continuous chlorination anti-
Should.
When continuous chlorination reaction starts, chlorination reaction raw material is advanced into by first order circulating pump, and chlorine is by the percentage for setting
Than being passed through through air inlet branch road 5, reaction raw materials, chlorine mix with recycle stock after enter chlorination reaction tower 1 in reacted；First
, into vapor-liquid separation is carried out after first order vapour liquid separator, the hydrogen chloride gas of generation are entered at tail gas for material in order reaction tower
Reason system, and unreacted complete material a part through subcooler 3 lower the temperature after enter second level circulating pump before with quantitative chlorine,
Recycle stock continues to carry out chlorination reaction into second level chlorination reaction tower after mixing, and is partly into the continuation of first order circulating pump
Circular response.
Material in the reaction tower of the second level is into carrying out vapor-liquid separation, the hydrogen chloride gas of generation after the vapour liquid separator of the second level
Body enters exhaust treatment system, and before the material part that unreacted is completed enters third level circulating pump after lowering the temperature through subcooler
Continue to carry out chlorination reaction into third level chlorination reaction tower after mixing with quantitative chlorine, recycle stock, be partly into second
Level circulating pump continues cycling through reaction.
Material in third level reaction tower is into carrying out vapor-liquid separation, the hydrogen chloride gas of generation after third level vapour liquid separator
Body enters exhaust treatment system, and reacts a part of overflow of material for completing and enter chloride material storage tank, and a part is through supercooling
After device cooling reaction is continued cycling through into third level circulating pump.
This continuous chlorination consersion unit is continuously passed through raw material from before first order circulating pump, and chlorine point three-level is quantitatively passed through, even
Continuous charging and discharging, so as to complete the purpose of continuous chlorination reaction.
Preferable implementation example of the present utility model is the foregoing is only, the utility model is not limited to, it is all in this reality
Within new spirit and principle, any modification, equivalent substitution and improvements made etc. should be included in guarantor of the present utility model
