Description

A reactor circulating cooling system

technical field

The utility model relates to the field of cooling systems, in particular to a circulating cooling system for a reactor.

Background technique

At present, the reaction kettles used in the chemical industry, medicine, coatings, adhesives and other industries are all heated by electric heating, and electric heating tubes are installed in the spacers of the reaction kettles, and filled with heat transfer oil. When cooling is required, steel pipes inside the spacer sleeve of the reactor are often used. Cooling water flows in the steel pipes to cool the heat transfer oil through heat conduction. The cooling speed is slow and the efficiency is low. Leaks and cracks appear on the steel pipe, and the cooling water infiltrates into the heat transfer oil. When the water reaches a certain level, heating and heating will cause the heat transfer oil-water mixture to expand rapidly, and it will be sprayed out from the overflow port on the spacer. After cooling, the heat transfer oil The volume decreases, and the volume of the oil cannot meet the actual demand for heating, which also causes waste and environmental pollution; because the reactor spacer is welded on the wall of the reactor, the maintenance of the cooling water coil pipe needs to be cut after the spacer is opened To carry out, the maintenance work is very complicated.

Relevant literature discloses a reaction kettle with a cooling water steel pipe inside the spacer, which uses the cooling water in the steel pipe to cool the heat transfer oil. However, this method still has the disadvantages of slow cooling speed, low efficiency, and complicated maintenance.
