Abstract
The utility model relates to a pressurizing polymerization device for manufacturing gas of polyvinyl acetate. The pressurizing polymerization device comprises a first polymerization kettle and a second polymerization kettle, wherein nitrogen valves are arranged on the top of the first polymerization kettle and the top of the second polymerization kettle respectively; the first polymerization kettle and the second polymerization kettle are connected with a condenser I and a condenser II respectively; explosion-proof membrane openings and non-condensable gas outlets are formed in the top of the condenser I and the top of the condenser II respectively; the non-condensable gas outlets in the condenser I and the condenser II are connected with a pressurizing groove by a pipeline; a water inlet valve is arranged on the top of the pressurizing groove; a plurality of overflow valves are arranged at the side end of the pressurizing groove; and an emptying valve is arranged at the bottom of the pressurizing groove. The pressurizing polymerization device has the advantages that polymerization reaction is performed towards the direction of producing products, energy conservation and consumption reduction are realized, the stable operation of vinyl acetate polymerization is facilitated, the production efficiency of high-viscosity products of polyvinyl alcohol is improved, and the quality of the products is stabilized.
Description
Technical field
The utility model relates to a kind of Vinyl Acetate Copolymer and makes the gas pressurization poly-unit.
Background technology
At present, the relation between supply and demand of domestic polyvinyl alcohol product is that drug on the market, and market competition is very fierce, and the produce market of high viscosity, high-polymerization degree relatively sells well, but the production that has now under technique, the appointed condition is very unstable, inefficiency.When manufacturer is located in the Plain, when height above sea level is not high, be normal pressure in the polymeric kettle, Vinyl Acetate Copolymer production is substantially depressed at standard atmosphere and is carried out, the local vinyl acetate between to for plastic polymerization production efficiency not high at height above sea level is stable, and manufacturer is positioned at the plateau, and height above sea level is higher, and vinyl acetate between to for plastic polymerization production efficiency rises and descends along with sea level elevation, cause whole production line efficiency low, percent polymerization and viscosity are unstable, cause production efficiency to descend, the quality product fluctuation.
The utility model content
The purpose of this utility model provides a kind of Vinyl Acetate Copolymer and makes the gas pressurization poly-unit, overcomes to be not suitable for the high altitude localities use in the currently available products, and quality product has fluctuation, the deficiency that production efficiency is low.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of Vinyl Acetate Copolymer is made the gas pressurization poly-unit, comprise the first polymeric kettle and the second polymeric kettle, its feature is, the top of described the first polymeric kettle and the second polymeric kettle is respectively equipped with nitrogen valve, the first polymeric kettle and the second polymeric kettle are connected with respectively condenser one and condenser two, condenser one and condenser two tops are respectively equipped with rupture disk mouth and not solidifying pneumatic outlet, not solidifying pneumatic outlet on condenser one and the condenser two is connected with pressurized tank by pipeline, the pressurized tank top is provided with water intaking valve, the pressurized tank side is provided with some surplus valves, and the pressurized tank bottom is provided with emptying valve.
The beneficial effects of the utility model are: a kind of Vinyl Acetate Copolymer that the utility model provides is made the gas pressurization poly-unit, make polyreaction be conducive to carry out to the direction that generates product, both reached energy-saving and cost-reducing, be conducive to again the stable operation of vinyl acetate between to for plastic polymerization, improve polyvinyl alcohol high-viscosity products production efficiency, stablized quality product.
Description of drawings
The below is described in further detail the utility model with reference to the accompanying drawings.
Fig. 1 is the structural representation that the described a kind of Vinyl Acetate Copolymer of the utility model embodiment is made the gas pressurization poly-unit.
Among the figure:
1, the first polymeric kettle; 2, the second polymeric kettle; 3, nitrogen valve; 4, condenser one; 5, condenser two; 6, rupture disk mouth; 7, not solidifying pneumatic outlet; 8, pipeline; 9, pressurized tank; 10, water intaking valve; 11, surplus valve; 12, emptying valve.
Embodiment
As shown in Figure 1, the described a kind of Vinyl Acetate Copolymer of the utility model embodiment is made the gas pressurization poly-unit, comprise the first polymeric kettle 1 and the second polymeric kettle 2, the top of described the first polymeric kettle 1 and the second polymeric kettle 2 is respectively equipped with nitrogen valve 3, the first polymeric kettle 1 and the second polymeric kettle 2 are connected with respectively condenser 1 and condenser 25, condenser 1 and condenser 25 tops are respectively equipped with rupture disk mouth 6 and not solidifying pneumatic outlet 7, not solidifying pneumatic outlet 7 on condenser 1 and the condenser 25 is connected with pressurized tank 9 by pipeline 8, pressurized tank 9 tops are provided with water intaking valve 10, pressurized tank 9 sides are provided with some surplus valves 11, and pressurized tank 9 bottoms are provided with emptying valve 12.
During use, open the nitrogen valve 3 on the first polymeric kettle 1 and the second polymeric kettle 2, valve-off when pressure arrives prescribed value, if descending to opening again, the still internal pressure regulates, polyreaction produces a large amount of gases, after gas passes through condenser 1 and condenser 25, also have not solidifying gas to enter pressurized tank 9 by pipeline 8, the liquid level of pressurized tank 9 is regulated with the water level in surplus valve 11 control flumes, not solidifying gas volume determines pressure, and after not solidifying gas volume increased, the pressure in the pressurized tank 9 can rise, pressurized tank 9 liquid levels can be discharged by liquid level regulation relief valve 11 and be regulated water seal heights this moment, thereby pressure-stabilisation were reached stablize the purpose of pressure polymerization.
The utility model is not limited to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present utility model; no matter but do any variation in its shape or structure; every have identical with a application or akin technical scheme, all drops within the protection domain of the present utility model.
