Abstract

A double chuck type heat transfer reactor belongs to a synthesizing device, which comprises a kettle body, a stirring device and a chuck. Outside the kettle body are provided a spiral semicircle-pipe chuck and a smooth type chuck. The inlet and outlet pipe of the two chucks are partitioned to make the reaction kettle adapt to the process requirement of rapid heating and cooling and further achieve simultaneous heating and cooling of the two chucks.

Description

Double fastener shell type heat transfer reactor

Technical field

The utility model belongs to synthesis device, is applied to condensation, the polymerisation of chemical industry materials such as petrochemical industry, biochemical industry, resin, emulsion, electroplate liquid.

Technical background

Reactor has obtained using widely in chemical industry as the visual plant in the Chemical Manufacture.Before 1985, the reactor that China uses, its heat transfer (cooling) chuck is smooth type chuck (seeing accompanying drawing 1); Domestic minority chemical enterprise is from external introduction spiral semicircle pipe clamp cover reactor (" Chinese coating " the 1st phase in 1993 after 1985, Zhu Guiyao, design, manufacturing and the application of spiral semicircle pipe clamp cover reactor), this reactor is compared with the former has following advantage: 1, reduce the kettle wall thickness, improve the bearing capacity of kettle; 2, heat transfer efficiency obviously improves; 3, the consumption of heat transfer carrier reduces greatly; 4, the heat carrier circulation rate is faster under the same traffic; 5, save great deal of steel.Because have so many advantage, after this domestic chemical enterprises entrust enterprise of the Ministry of Aero-Space Industry to copy.Because at that time material, manufacturing (cold-working, welding) technology and workman require to have big gap with present technical merit to the manufacture craft of this equipment, the reactor cost height of making is (because of the restriction of prevailing condition, the semicircle pipe can only be cut open with homogeneous tube, earlier roll shaping by kettle and end socket shape with homogeneous tube, mill half again), the cycle is long, and quality can not get guaranteeing, the semicircle pipe joint easily leaks, and is difficult to all the time in a long time apply.The spiral semicircle tube reaction still of the personnel of organizational technology of our company development in 1993, and manufactured and designed spiral semicircle pipe press process forming machine (with steel band compacting semicircle pipe), with key equipments such as semicircle pipe furling plate round machine shapings, adopt advanced solder technology, saved production cost greatly, shortened the production cycle, obtained using widely in chemical industry at present.

Although chemical industry has been accepted spiral semicircle tube reaction still, still find that there is the phenomenon of leaking in the semicircle pipe joint recent years, mainly concentrate on hot and cold carrier and import and export adapter place appearance leakage.By analysis, be not in manufacture process, to have reduced quality requirement, but variation has taken place in user's production technology, from heating originally several hours, be incubated a period of time again, and then cool; Now change into being warmed to and need after the uniform temperature cool to a certain temperature very soon, so repeatedly.Hot and cold like this carrier is imported and exported adapter place and is existed very big thermal (temperature difference) stress (because semicircle pipe and kettle weld together, carrier is imported and exported to take over semicanal and is welded together, when heat carrier heats in to still, take over very fast arrival and heat carrier consistent temperature, when reaching predetermined temperature in the reactor, when needing very fast cooling by technological requirement, take over very fast arrival and cold carrier consistent temperature, and the semicircle pipe is subjected to the influence of material in the still, temperature is still very high, expansion rate is different, produces bigger thermal (temperature difference) stress in the joint; When material need heat up once more in the opposite still, take over very fast arrival and heat carrier consistent temperature, and the semicircle pipe is subjected to the influence of material in the still, temperature heats up so not fast, contraction rate is different, produces bigger thermal (temperature difference) stress equally in the joint, and this is the main cause that leakage appears in adapter place.

Summary of the invention

The utility model is just in order to overcome above-mentioned deficiency, provide a kind of can reach be rapidly heated, fast cooling, guarantee product quality, the double fastener shell type heat transfer reactor of avoiding spiral semicircle pipe union nipple to leak is to adapt to the requirement of chemical industry technique change.The main improvement is to increase the smooth type chuck outside spiral semicircle pipe clamp cover, makes reactor have dual chuck, and the turnover pipe of two chucks is design separately, does not disturb mutually.Specifically be to implement like this: double fastener shell type heat transfer reactor, comprise kettle, agitating device, chuck, it is characterized in that kettle is provided with spiral semicircle pipe clamp cover and smooth type chuck outward simultaneously, the turnover pipe position of two chucks separates design.Add a level and smooth chuck outside spiral semicircle tube reaction still again, this chuck is made easily, and quality guarantees that easily material can be a same material with kettle.Feed hot cold carrier in semicircle pipe and smooth type chuck, promptly temperature does not just have rapid variation in same chuck layer, thereby avoids spiral semicircle pipe union nipple to leak the purpose that reaches quick cooling simultaneously or heat.

Be subjected to the influence of temperature jump for fear of the semicircle pipe joint; produce bigger thermal (temperature difference) stress; cause joint to leak; therefore outside the turnover pipe of spiral semicircle pipe clamp cover, be provided with the protection cage ring in addition; avoided the cold carrier in the smooth type chuck to touch the turnover pipe joint that hot semicircle pipe clamp overlaps carrier like this, heat carrier does not affect cold carrier turnover pipe joint on the smooth type chuck in the semicircle pipe.

If technology allows to increase inner coil pipe in still,, but can clean the problem that bothers by band after increasing inner coil pipe with the increase heat transfer area.

The utility model makes reactor can adapt to the technological requirement of the fast cooling that is rapidly heated by add a level and smooth chuck again outside spiral semicircle tube reaction still, can also reach heating simultaneously in the double jacket, the effect of cooling simultaneously.

The specific embodiment

Double fastener shell type heat transfer reactor; comprise kettle 2, agitating device 1; kettle 2 outer spiral semicircle pipe clamp cover 4 and the smooth type chucks 3 of being provided with simultaneously; the turnover that 5 positions and spiral semicircle pipe clamp cover 4 is managed in the turnover of smooth type chuck 3 is managed 6 positions and is separated design, the turnover pipe 6 outer protection cage rings 7 that are provided with in addition of spiral semicircle pipe clamp cover 4.

Use 1, in the electroplate liquid synthetic reaction process, when its technological requirement is warming up to 150 ℃ when material in the still, need very fast cooling, if do not take cooling, material temperature will continue to raise (because temperature of charge reaches 150 ℃ in still, at this moment the temperature in the chuck is 180-200 ℃) in the still, and influence the quality of product.This reactor can cut out the heat carrier imported valve earlier, feeds cold carrier from another chuck and cools off, and can reach the requirement of user's technology like this.

Use 2, in emulsion synthesis reaction vessel process, require clear and definite requirement,, easily glue pot even burnt pot, influence the quality of product if surpass technological requirement and do not have the fast cooling measure to temperature controlled.The intensification cooling-down effect of this reactor is remarkable, can satisfy user's technological requirement.

This equipment of employing is used to produce products such as resin, curing agent, can reach desirable effect equally.
