Description
Technical field
Patent of the present invention relates to a kind of chemical industry equipment, and what be specifically related to is the PVC resin polymerization still of chuck in a kind of the disposing.
Background technology
In the polyvinyl chloride resin production process, polymeric kettle is a main production equipments.Its technical feature quality directly has influence on output, quality and the performance driving economy of polyvinyl chloride (PVC) RESINS.At present, homemade PVC resin polymerization still has 13.5m
3, 30m
3, 48m
3, 70m
3Etc. several polymeric kettles.These polymeric kettles are main still types of domestic production polyvinyl chloride (PVC) RESINS.Along with the polyvinyl chloride industrial expansion, polymeric kettle also towards most economical, production efficiency is high, construction and maintenance cost is low, good product quality, direction that output is big develop.Jinxi Chemical Machinery (Group) Co., Ltd. has developed the polymeric kettle of interior chuck production polyvinyl chloride (PVC) RESINS.
In vinylchlorid suspension polymerization process, exist the problem of heat-transfer effect difference always, have a strong impact on the yield and quality of polyvinyl chloride product.General pvc polymerizer heat transfer structure is the kettle external jacket, heat-transfer capability has a strong impact on the performance of polymeric kettle throughput, especially along with the maximization of polymeric kettle volume, the polymeric kettle body surface area reduces, and heat-transfer capability has restricted the throughput of polymeric kettle more.Although some large-scale polymeric kettle is provided with external condenser,, increased the cost and the maintenance cost of equipment undoubtedly though can alleviate the biography ability.Therefore the design of the heat transfer structure of polymeric kettle plays a part very important to the production capacity of polymeric kettle.
The polymeric kettle type of cooling had chuck cooling (comprising conventional jacket, spiral stream guidance chuck), the cooling of interior cold apron, external half-pipe jacket in the past.All there are many disadvantages in these structures, utilize conventional jacket when cooling because water coolant is entered by the chuck end opening, through the chuck ring go straight up to and on, by outflow suitable for reading, flow velocity is very low, turbulent flow is not enough, the cooling performance extreme difference.Though adopting the spiral stream guidance chuck to conduct heat makes moderate progress, processing preferably under the situation, can obtain bigger flow velocity (2～3m/s), thereby increase substantially heat-transfer effect, but because of being subjected to the restriction that machining is made, and water coolant is walked " short circuit " easily, makes heat transfer coefficient low, so its method of cooling also haves much room for improvement.
Summary of the invention
The technical problem to be solved in the present invention is that it disposes the interior jacket structured of high heat transfer efficient for the polyvinyl chloride industry provides a kind of novel polymeric still.
The technical scheme that adopts is as follows:
Kettle partly adopts in the current global mechanism spiral jacket structured, and end socket partly adopts the semicanal external jacket.
Concerning the PVC resin polymerization still that disposes external jacket, the kettle wall thickness is the principal element that influence is conducted heat, its thermal resistance is more than 60% of entire thermal resistance, reducing the kettle wall thickness is the major measure that improves polymerization reactor heat transfer efficient, but the kettle wall thickness is stressed again and the restriction of the strength of materials, can not endless attenuate.
Yet, concerning the PVC resin polymerization still that disposes external jacket, pressure between interior chuck and the kettle and internal design pressure power adopt the pressure equilibrium interlocking, chuck does not bear pressure in making, therefore the wall thickness of chuck does not depend on kettle pressure in, wall thickness can be very thin, and the thermal resistance of its wall thickness descends greatly, thereby improved the heat transfer coefficient of still greatly.
The PVC resin polymerization still of chuck in a kind of the disposing, comprise kettle, transmission mechanism, interior chuck, kettle top is equipped with external condenser, end socket outside, kettle top is equipped with the semicanal external jacket, the bottom head outside is equipped with the semicanal external jacket, and each semicanal external jacket pipe is separately installed with entrance of cooling water and cooling water outlet; On the kettle 1 cylindrical shell straight section inwall interior chuck is installed, interior chuck is provided with entrance of cooling water and cooling water outlet, does not have short circuit phenomenon with chuck circulation cooling in guaranteeing; Kettle is installed on the skirt, and the skirt that a breasting of equipment is located on the kettle is fixing with the installation basis; Autoclave body bottom is equipped with drain hole; The kettle inside middle is equipped with the hollow symmetrical baffle plate of V-arrangement, and the hollow symmetrical baffle plate of V-arrangement disposes entrance of cooling water and cooling water outlet, and is cooling water circulation to carry out, and has baffle effect and carries out heat exchange; Be provided with extension human body admission port at the kettle top, the clear kettle device bracing frame of this extension human body admission port double as is provided with the human body access cover on the extension human body admission port, and charging opening; Kettle 1 inside is equipped with stir shaft, and stir shaft is equipped with stirring rake; The entire equipment length-to-diameter ratio is moderate, and it is more moderate to stir shearing force, and reaction is evenly carried out, and is suitable for the mixing of materials of polyvinyl chloride medium.
Transmission mechanism of the present invention adopts down inserting type structure formation, comprises electric motor, step-down gear, oily station, frame, bearing box, mechanical seal; The oil station is connected with mechanical seal by oil line, and electric motor is connected with step-down gear, and frame is equipped with step-down gear, step-down gear is equipped with seal shaft, and seal shaft is connected with stir shaft, and stirring rake is installed on the stir shaft, so just, can realize stirring material, make normally smooth operation of entire equipment.
Chuck comprises chuck, the interior chuck of current global mechanism semicanal in chuck in the spiral stream guidance, the interior chuck of current global mechanism angle steel, the current global mechanism pipe nipple in above-mentioned;
Chuck contacts the inwall polished finish in above-mentioned with medium, polishing precision Ra≤0.1 μ m;
Above-mentioned kettle nominal volume is 105m
3Length-to-diameter ratio 1.45; Height 13.3m; Kettle 1 nominal diameter 4.2m.
Material reacts wants heat release, temperature of reaction will be controlled in the specified range just normally carries out, the heat transfer of equipment is in time shifted out reaction heat by interior chuck, the outside semicanal external jacket of top end socket, the outside semicanal external jacket of bottom head and still acrosome external condenser, the interior temperature of kettle is remained in the stated limit, guarantee to react and normally carry out.Material was discharged by drain hole after reaction was finished.
Jacket of polymerization of the present invention is interior chuck, for China's PVC industry production has increased a new reator kind, China PVC polymeric kettle structure design is reached advanced world standards, and will promote the development of China PVC industry.
Advantage of the present invention is: equipment running cost is low, production efficiency is high, device security is reliable, produces good product quality.
