Abstract
The utility model relates to a device for recovering resin particles from polymerized unreacted vinylchloride monomers. The device comprises a separator, a separator water supplementation pipeline, a circulating pipe, a valve of the circulating pipe, a circulating pump and a resin recovery pipe. According to the device, an unreacted monomer gas is circularly sprayed to be circularly eluted, and the inner circumferential sidewall of the separator is used for changing the flow direction of the gas to form a cyclone separation effect, so that a great number of suspended resin particles in the gas are entrapped or settled at the bottom of the separator to fulfill the aims of recovering the resin particles and reducing resin loss; and the device has the characteristics of simple principle, high recovery efficiency, short recovery process processing period and the like.
Description
Technical field:
The utility model relates to a kind of device that reclaims resin particle in the chloroethylene polymerization unreacted monomer, particularly relates to reclaiming the resin particle of carrying secretly in the unreacted monomer gas in the suspension method chloroethylene polymerization.
Background technology
In the suspension type polyvinyl-chloride production technique; Reacted vinyl chloride monomer after the polymerization is because the pressure release effect; The liquid monomer generating gasification, volumetric expansion produces a large amount of foams with dispersion agent residual in the polymeric size; Have a large amount of resin particles in the unreacted monomer gas to making, must recycle.Traditional way of recycling adopts foam catcher to handle, and its principle is that unreacted monomer gas inlet pipe inserts below the foam catcher liquid level, and gas is washed through contacting to take off with water, and the resin in the foam is trapped in the water.But because big or gas is fast when too fast at pressure recovery, it is not only much but also faster that gas bubbling in water forms foam, causes to take off to wash difficulty and strengthen, and still can't avoid taking place the phenomenon that unreacted monomer gas is carried resin particle secretly.Adopt tradition to reclaim process method; The polymeric kettle discharging time receives the restriction of discharging speed, generally will reach 40～50 minutes, and the resin of carrying secretly in the unreacted monomer gas can't use and cause waste; And the resin of carrying secretly causes damage to recovery system, finally influences the ordinary production of polymerization process.
Summary of the invention:
The utility model purpose provides a kind of device that reclaims resin particle in the chloroethylene polymerization unreacted monomer, and it can reclaim the resin particle of carrying secretly in the polymerization unreacted monomer gas fast, enhances productivity, and shortens the polymerization production cycle, reduces to produce to consume.
The utility model solves the technical scheme that its technical problem adopted: a kind of device that reclaims resin particle in the chloroethylene polymerization unreacted monomer comprises separator, separator moisturizing pipeline, circulation tube and valve thereof, recycle pump, resin TFL.
Above-mentioned a kind of device that reclaims resin particle in the chloroethylene polymerization unreacted monomer, its separator is provided with air outlet, shower, inlet mouth, discharge port.
Above-mentioned a kind of device that reclaims resin particle in the chloroethylene polymerization unreacted monomer; Its separator sidewall is an inner periphery shape; Inlet pipe gets into separator by the inlet mouth tangential; Be beneficial to the formation of self cyclonic separation, gas phase is discharged from the top, resin particle and water liquid converge the separator bottom along the separator inwall.
Above-mentioned a kind of device that reclaims resin particle in the chloroethylene polymerization unreacted monomer; Its inlet mouth is located at separator 1/3 eminence, and the separator top is located in the air outlet, and shower is located at separator 2/3 eminence; Discharge port is located at the bottom of separator, is beneficial to spray, round-robin realization.
Above-mentioned a kind of device that reclaims resin particle in the chloroethylene polymerization unreacted monomer, its circulation tube connects discharge port, and circulation tube, resin TFL, separator moisturizing pipeline are positioned at outlet of circulating pump.
Because of reclaiming the resin processing unit to conventional polymeric, transforms the utility model; Simple and convenient; Can the suspending resin of gas entrainment in the unreacted monomer be taken off to wash and, reduce the loss of resin and to the influence of equipment, principle is simple, organic efficiency is high, it is short to reclaim the art breading cycle; Have bright development prospect, can be widely used in reclaiming in the suspension method chloroethylene polymerization resin particle of carrying secretly in the unreacted monomer gas.
Description of drawings:
Fig. 1 is the structural representation of the embodiment of the utility model.
Among Fig. 1,1 is the resin TFL, and 2 is the inlet pipe stopping valve, and 3 is inlet pipe, and 4 is separator moisturizing pipeline; 5 is resin recovery line stopping valve, and 6 is recycle pump, and 7 is the circulation tube stopping valve, and 8 is circulation tube; 9 is the shower stopping valve, and 10 is separator, and 11 is shower, and 12 is escape pipe.
Embodiment:
With reference to accompanying drawing 1; Unreacted monomer gas gets into separator 10 high 1/3 places through inlet pipe stopping valve 2 by inlet pipe 3 tangentials, forms cyclonic separation, and gas phase is escape pipe 12 discharges from the separator top; Get into the hypomere operation, resin particle and water converge the separator bottom along the separator inwall.The separator bottom is connected with circulation tube 8, and when unreacted monomer gas got into separator by inlet pipe, shower 11 formed self spray circulation with circulation tube through recycle pump 6 and valve 7 thereof in separator inside; Resin particle in the unreacted monomer gas is carried out wash-out; Resin particle acquires a certain degree in water, opens resin recovery line stopping valve 5, closes shower stopping valve 9; The water lotion that will have a large amount of resin particles through recycle pump; Be recycled to the leading portion operation by resin TFL 1, keep the liquid level of water in the separator simultaneously through separator moisturizing pipeline 4, thereby realize spray, the purpose that circulates, reclaims.
This apparatus features is through circulated sprinkling unreacted monomer gas to be circulated to take off to wash; And utilize the separator sidewall to be inner periphery shape; Change gas and move towards to form the cyclonic separation effect, make a large amount of suspending resin particles of carrying secretly in the gas hold back or fall to the separator bottom, realize that resin particle reclaims; Reduce the purpose that resin runs off, have characteristics such as principle is simple, organic efficiency is high, the recovery art breading cycle is short.
