Abstract
A kind of polymerization kettle device for eliminating connecting pipe security risk, including polymeric kettle, polymeric kettle are fixedly connected with connecting pipe, and connecting pipe is equipped with safety valve, between safety valve and connecting pipe, are equipped with burst disk.Connecting pipe outer wall between polymeric kettle and burst disk, it is arranged with a heat exchange jacket, heat exchange jacket is equipped with water inlet and discharge outlet, is cooled down by connecting pipe of the recirculated water in heat exchange jacket between polymeric kettle and burst disk, so that the vinyl chloride gas in pipeline is condensed and reenters in polymeric kettle.The utility model is simple in structure, reasonable design, convenient for installation and maintenance, of low cost.It is completely suitable for the production technology of suspension polymerization production Corvic.
Description
Technical field
The utility model is related to the chemical production equipments more particularly to a kind of elimination connecting pipe peace in a kind of Chemical Manufacture
The polymerization kettle device of full hidden danger.
Background technology
Suspension polymerization produces Corvic(PVC)General technology process be:Free radical chain lock sudden reaction, chain
Initiation, chain growth, chain termination, chain tra nsfer and elementary reaction, belong to strong exothermal reaction:nCH2=CHCL→(CH2-CHCL)-n+
96.3~108.9KJ/mol.The reaction mass loading of suspension polymerizer accounts about 74.5% or so of kettle volume;Reaction system
Environment:Liquid, temperature 45 C~65 DEG C, pressure 0.8MPa~1.0MPa;Pressure is largely steamed from vinyl chloride saturation in kettle
Air pressure, that is to say, that polymeric kettle 25.5% volume of residue is largely vinyl chloride gas, also includes the pipeline short section of connection kettle top.
Under reaction environment in kettle, vinyl chloride gas is easy to the autohemagglutination on kettle wall, pipeline short circuit inner wall and forms autopolymer and be adhered
On its inner wall, long can then block pipeline, especially form autopolymer on the pipeline of connection burst disk, then can seriously threaten
The safe operation of polymeric kettle.
Utility model content
The purpose of this utility model is that overcome the shortage of prior art place, provide it is a kind of simple in structure, it is easy to use
The polymerization kettle device of connecting pipe security risk is eliminated, a kind of elimination connecting pipe security risk described in the utility model is gathered
It includes polymeric kettle to close kettle device, and polymeric kettle is fixedly connected with connecting pipe, and connecting pipe is equipped with safety valve, be located at safety valve with
Between connecting pipe, it is equipped with burst disk.Connecting pipe outer wall between the polymeric kettle and burst disk is arranged with heat exchange folder
Set, heat exchange jacket is equipped with water inlet and discharge outlet, by the recirculated water in heat exchange jacket between polymeric kettle and burst disk
Connecting pipe cools down, and so that the vinyl chloride gas in pipeline is condensed and reenters in polymeric kettle.To reach oneself in connecting pipe
It is poly- to eliminate, security risk is reduced, and improve the purpose of one-pot production capacity.
Further, the caliber of heat exchange jacket is 2.5 times of connecting pipe caliber, to ensure the abundant cold of connecting pipe
But.
Further, the circulating water temperature in heat exchange jacket is 22 DEG C~30 DEG C, while to ensure safety in production, connecting tube
Road is adequately cooled.
When the utility model is used, it is passed through for burst disk connecting pipe present in present polymeric kettle production technology, valve
The problem of often blocking safety relief channel from coalescence increases heat exchange jacket in burst disk connecting pipe, and heat exchange jacket is logical to follow
Ring water forms heat exchange with the vinyl chloride gas in connecting pipe, and the vinyl chloride gas temperature in connecting pipe forms small after reducing
Drop participates in reaction since gravity reenters, prevents vinyl chloride autohemagglutination in connecting pipe to reach, eliminate peace in kettle
Full hidden danger improves the purpose of one-pot production capacity again.
The utility model has the beneficial effects that:The utility model is simple in structure, reasonable design, convenient for installation and maintenance, cost
It is cheap.It is completely suitable for the production technology of suspension polymerization production Corvic, recirculated water and company are led to by heat exchange jacket
Vinyl chloride gas in take over road forms heat exchange, and the vinyl chloride gas temperature in connecting pipe forms droplet after reducing, weight
Newly enter and participate in reaction in kettle, can reach prevents vinyl chloride autohemagglutination in connecting pipe, eliminates safe hidden trouble and improves one-pot production capacity
Effect.Contribute to reduce stop frequency in reproduction, reduces production cost.
Description of the drawings
Fig. 1 is a kind of structural representation of polymerization kettle device for eliminating connecting pipe security risk described in the utility model
Figure;
Reference numeral:
1- safety valve 2- burst disk 3- connecting pipe 4- heat exchange jacket 5- polymeric kettles
The embodiments will be further described with reference to the accompanying drawings for the realization, functional characteristics and advantage of the utility model aim.
Specific implementation mode
Referring to Fig.1, a kind of polymerization kettle device for eliminating connecting pipe security risk described in the utility model, including polymerization
Kettle 5, polymeric kettle 5 are fixedly connected with connecting pipe 3, and connecting pipe 3 is equipped with safety valve 1, is located at safety valve 1 and connecting pipe 3
Between, it is equipped with burst disk 2.3 outer wall of connecting pipe between the polymeric kettle 5 and burst disk 2, is arranged with a heat exchange jacket 4, changes
Thermal jacket 4 is equipped with water inlet and discharge outlet, passes through company of the recirculated water in heat exchange jacket 4 between polymeric kettle 5 and burst disk 2
Take over road 3 cools down, and so that the vinyl chloride gas in pipeline is condensed and reenters in polymeric kettle 5.To reach oneself in connecting pipe 3
It is poly- to eliminate, security risk is reduced, and improve the purpose of one-pot production capacity.
Further, the caliber of heat exchange jacket 4 is 2.5 times of 3 caliber of connecting pipe, to ensure the abundant of connecting pipe 3
It is cooling.
Further, the circulating water temperature in heat exchange jacket 4 is 22 DEG C~30 DEG C, while to ensure safety in production, connection
Pipeline 3 is adequately cooled.
When the utility model is used, for 2 connecting pipe 3 of burst disk, valve present in 5 production technology of present polymeric kettle
The problem of often blocking safety relief channel from coalescence, heat exchange jacket 4, heat exchange jacket are increased in 2 connecting pipe 3 of burst disk
4 logical recirculated waters form heat exchange with the vinyl chloride gas in connecting pipe 3, and the vinyl chloride gas temperature in connecting pipe 3 reduces
After form droplet, reaction is participated in kettle since gravity reenters, to reach prevent in connecting pipe 3 vinyl chloride from
It is poly-, eliminate safe hidden trouble and improve the purpose of one-pot production capacity.
In conclusion the utility model is simple in structure, and it is easy to use, it is more conducive to Chemical Manufacture use.
