Description

A kind of electrical heating cold oil cooling system

Technical field

The utility model relates to the heat transmission equipment of chemical industry, especially a kind of electrical heating cold oil cooling system.

Background technology

In chemical process, temperature is a key factor of product quality quality, and a lot of chemical products need to could efficiently be synthesized more than 100 DEG C, so generally need heat-conducting oil heating. Electric-heating heat-conductive oil system is made up of hotline heater, circulating line, oil transfer pump, heat exchanger tube four parts. Conduction oil is heated to after serviceability temperature in heater, be transferred to heat exchange pipeline through pump, by indirect heat exchange, heat passed to the material that needs heating, after heat transfer, the conduction oil that temperature reduces comes back to heater through circulating line, is then heated to serviceability temperature circulating-heating. Complete when heating material process, heater stops the heating to conduction oil, and now the conduction oil temperature in circulating line and heat exchanger tube is still very high, and material cooling is slow, post processing difficulty.

In view of the foregoing, the structure of existing heat-exchange system needs to improve.

Utility model content

The purpose of this utility model is in order to overcome deficiency of the prior art, a kind of electrical heating cold oil cooling system is provided, solve electric-heating heat-conductive oil system and left standstill the slow problem of cooling, avoid the generation of side reaction in heat transmission equipment, shorten temperature fall time, be conducive to realize higher economic benefit, in the complete fast cooling process that realizes material of heating material. Save time, and can avoid the generation of side reaction.

The utility model to achieve these goals, adopt following technical scheme: a kind of electrical heating cold oil cooling system, be by: reactor, chuck, electrical heating wire, deep fat storage tank, cold oil storage tank, pump, cooler, turnover oil pipe, hot oil inlet pipe, hot oil return pipe, heat are overflowed oil pipe, cold oil inlet pipe, cold oil return pipe, cold circulation pipe, are entered valve, total valve, hot oil return valve, heat overflow valve, cold circulation valve, cold oil return valve form, reactor periphery arranges chuck, on the inwall of chuck, be fixedly installed at least two electrical heating wires, between chuck bottom and pump, turnover oil pipe is set, on turnover oil pipe, arrange into valve near pump one side, near chuck one side, total valve is set, chuck top arranges two oil-outs, between one of them oil-out and deep fat storage tank, heat is set and overflows oil pipe, heat is overflowed and on oil pipe, heat is set and overflows valve, hot oil inlet pipe is set between the oil-out of described deep fat storage tank and pump, between another oil-out and cold oil storage tank, cold circulation pipe is set, on cold circulation pipe, near reactor one side, cold circulation valve is set, near cold oil storage tank one side, cooler is set, cold oil inlet pipe is set between the oil-out of described cold oil storage tank and pump, total valve and enter turnover oil pipe between valve and the oil-in of deep fat storage tank between hot oil return pipe is set, hot oil return valve is set on described hot oil return pipe, total valve and enter turnover oil pipe between valve and the oil-in of cold oil storage tank between cold oil return pipe is set, cold oil return valve is set on described cold oil return pipe.

Operation principle is: in the time that reactor needs heat supply, it is pressurized that oil in deep fat storage tank enters pump through hot oil inlet pipe, open into valve, total valve and heat are overflowed valve, close other valve, enter the chuck of reactor periphery through turnover oil pipe, oil is full of after chuck, unnecessary oil enters heat from the oil-out of chuck top and overflows oil pipe and flow back to deep fat storage tank, close each valve, to electrical heating wire, energising makes the oil heating in its heat exchanging cavity, oil temperature is increased to design temperature, deep fat carries out indirect heat exchange by the material in reactor wall and reactor, oil temperature reduces, make deep fat remain on stationary temperature by the power of adjusting electrical heating wire, after insulation a period of time, make the material in reactor be heated to design temperature, open total valve and hot oil return valve, close other valve, deep fat in chuck enters turnover oil pipe and hot oil return pipe flows back to deep fat storage tank, open into valve, total valve and cold circulation valve, close other valve, it is pressurized that cold oil in cold oil storage tank enters pump through cold oil inlet pipe, enter chuck through turnover oil pipe, cold oil carries out indirect heat exchange by the material in reactor wall and reactor, the cold oil temperature rise in chuck, enter cooler cooling through cold circulation pipe, cold oil after cooling flows back to cold oil storage tank, then enters heat exchange cavity through pump, and the material being circulated in reactor by above process is cooled to design temperature, open total valve and cold oil return valve, close other valve, the cold oil in chuck enters turnover oil pipe and hot oil return pipe flows back to cold oil storage tank.

The beneficial effects of the utility model are: the utility model has solved electric-heating heat-conductive oil system and left standstill the slow problem of cooling, has avoided the generation of side reaction in heat transmission equipment, shortens temperature fall time, are conducive to realize higher economic benefit. Increase cold oil storage tank and cooler, possessed heating function and cooling function, in the complete fast cooling process that realizes material of heating material. In Chemical Manufacture, temperature-fall period is not only lost time slowly, and may cause side reaction, affects product purity. The utility model can not only save time, and can avoid the generation of side reaction.
