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 agitated 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: water vapour is used in heating, and brine ice is used in sub-zero cooling, checker in chuck.Its advantage is that method is simple.Its shortcoming is when colding and heat succeed each other, to be easy to make steam and condensed water to sneak in the brine ice; Perhaps be easy to brine ice is misprinted sewer, so heat, loss of refrigeration capacity are all very big, and because the intrusion of steam condensate (SC); Brine strength is thin out very soon, rotten; Can not use, influence cooling system and normally move, guarantee not to produce and normally carried out.
