Abstract
The invention relates to a process for heating and cooling materials in a reaction kettle through a jacket by using a heat carrier. The process completes five working procedures by six loops. The loops are as flollows: a heat conduction oil heating loop: heat oil flows out from an oil outlet of a boiler and comes in and out of the jacket of the reaction kettle through a pipeline and a valve for circularly heating; a heating and cooling shift loop: the heat oil is sent back to the boiler by an oil pump through a pipeline; a cold conduction heat oil cooling loop and an ice salt water cooling loop: cold oil enters the jacket of the reaction kettle from an outlet of a cool oil tank by the pump through a pipeline and a cooler and returns to the cool oil tank through a pipeline provided with a balance valve; ice salt water returns to a cooling device from a refrigerating device through a cooler shell side and a pipeline, and cold conduction heat oil is circularly cooled in the cooler; a cool heating shift loop: cold oil comes out of the jacket of the reaction kettle, passes through the pipeline and returns to the cold oil tank from an inlet by the pump through the cooler; a cold oil pre-cooling loop: cold oil comes out of the outlet of the oil tank and returns to the cold oil tank by the pump through the pipeline and the shell side of the cooler introducing ice salt water. The invention has the advantages that the loop structure is compact, the process is stable, the heat exchange efficiency is high, and the high temperature and the low temperature are 300 DEG C and 15 DEG C below zero respectively.
Description
Technical field
The present invention relates in the chemical process material in reactor heating, cooling, particularly with a kind of heat-carrying agent through chuck to material in reactor heat, the cooling technology field.
Background technology
The period that some chemical products has in reactor needs heat, and temperature requirement is had nothing in common with each other, and what have requires below the Baidu, and what have requires more than the Baidu; The period that has needs cooling, requires temperature also to have nothing in common with each other: the general low temperature of the requirement that has, what have requires subzero tens degree.Even the requirement that has is heated, cooling hockets repeatedly, and this just causes very big difficulty to heat exchanging process.Traditional handicraft is: heating water vapour, sub-zero cooling brine ice, checker in chuck.Its advantage is that method is simple.Its shortcoming is to be easy to make steam and condensed water to sneak in the brine ice when colding and heat succeed each other, perhaps be easy to brine ice is misprinted sewer, therefore heat, loss of refrigeration capacity are all very big, and because the intrusion of steam condensate (SC), brine strength is very fast thin out, rotten, can not use, influence cooling system and normally move, not guarantee to produce and normally carry out.
Summary of the invention
The objective of the invention is, provide with a kind of heat-carrying agent through chuck to reactor in material heating, process for cooling.
Technical scheme of the present invention is:
The present invention is a heat-carrying agent with the 320# conduction oil, 320 ℃ of 200 ℃ of its flash-points, condensation point-20 ℃, flow process 〉=340 ℃, density 0.83～0.85, maximum operation (service) temperatures.Also can use the 350# conduction oil.
With heat conducting oil boiler (hereinafter to be referred as boiler) heating conduction oil.Brine ice cooling conduction oil with the refrigerating plant preparation.Brine ice is the aqueous solution that contains calcium chloride 30～40%.Refrigerating plant is made up of refrigeration machine and cryosel tank.
Heat conduction oil, cool off conduction oil with boiler with refrigerating plant.Material in reusable heat conduction oil, cold heat-conducting oil heating, the cooling reactor.
The equipment that uses has: heat conducting oil boiler, reactor, oil pump, cold oil case, cooler and refrigerating plant thereof.These equipment connect and compose 6 loops through pipeline separately, finish the work of 5 procedures in heating, the process for cooling in 6 loops.6 loops are that cooling (heat extraction oil) loop, cold conduction oil cooling circuit, cooling commentaries on classics heating (row's cold oil) loop, the pre-cold loop of cold oil and brine ice cooling circuit are changeed in heat-conducting oil heating loop, heating.Corresponding by-pass valve control is all arranged in each loop.5 procedures are heat-conducting oil heating, heating commentaries on classics cooling, the cooling of cold conduction oil, cool off to change and heat and the cold oil precooling.
Now the structure in each loop and the application in technical process thereof are described below:
The heat-conducting oil heating loop, by boiler, reactor by the road and valve connect to form.Deep fat flows out from the boiler oil-out, is entered, is flowed back to the boiler oil inlet tube by last mouthpiece through valve and pipeline by reacting kettle jacketing lower linking tube mouth through valve and pipeline.Circulation heating, till reaching the heating process requirement.Wherein conduction oil Wen Keda is 200～300 ℃.Finish heating back off-response still chuck import and export valve.
Cooling (heat extraction oil) loop is changeed in heating, reaches valve by the road by boiler, reactor, oil pump and connects to form.Open related valve during operation, start oil pump, deep fat flows back to boiler from reacting kettle jacketing lower linking tube mouth nationality oil pump.
Cold conduction oil cooling circuit, by cold oil case, reactor, oil pump, cooler, reach valve by the road and connect to form.Open related valve during operation, start oil pump and refrigerating plant, cold oil is sent in the reacting kettle jacketing through cooler by cold oil case mat oil pump.Cold oil circulates in the loop.Brine ice by the refrigerating plant preparation circulates in the shell side of cooler by the road, cold oil circulates in the tube side of cooler, and the two carries out heat exchange in cooler, and the minimum temperature of cold oil is-15 ℃.After work is finished, close related valve, termination of pumping and close refrigerating plant.
Heating (row's cold oil) loop is changeed in cooling, is connected to form through pipeline and valve thereof by cold oil case, reactor, cooler, oil pump.Open related valve during operation, start oil pump, send cold oil back to the cold oil case.
The pre-cold loop of cold oil, by cold oil case, cooler, oil pump by the road and valve connect to form.Open related valve during operation, start oil pump and refrigerating plant, cold oil reaches valve mat oil pump by the road and sends the cold oil case back to through the tube side of the cooler of the logical brine ice of shell side again from the cold oil case.
Valve in each loop mostly is common valve, can't independently be named, and can only use the Arabic numerals mark.Oil pump in the loop with gear pump for well.
Advantage of the present invention is, uses with a kind of heat-carrying agent material heating, cooling in the reactor, and is easy to use.Each loop structure compactness, floor space are little, and shared oil pump, valve are reduced expenses.Process stabilizing, heat exchanger effectiveness height; 200～300 ℃ of heating Wen Keda, chilling temperature can reach subzero-15 ℃.
