Description

Non-contact cooling units for chemical reactors

Technical field

The utility model relates to the technical field of chemical engineering, in particular to a non-contact cooling device for chemical reactors.

Background technique

In chemical operations, the following three basic cooling systems are usually used, namely cooling water circulation cooling system, chilled water circulation refrigeration system and chilled brine cooling system. Among them, the cooling water circulation system is the most widely used. It is suitable for reactions at normal temperature and is relatively energy-saving. The working principle is to use the fan operation to dissipate the heat of the cooling water to the atmosphere, thereby exchanging hot and cold air to achieve cooling. Usually the cooling temperature difference can be 3 to 5 degrees Celsius, and the temperature can be cooled to 25 degrees to 30 degrees. In addition, the chilled water circulation system consists of a compressor, expansion valve, evaporator and condenser. The circulating cooling water temperature can be controlled at 7 to 12 degrees, and the return water temperature can be controlled at 12 to 15 degrees Celsius. For example, the reactor jackets, half-pipe jackets and inner coils of chemical reactors and food brewing kettles are filled with chilled water to reduce the temperature of the materials. The above-mentioned cooling systems all need to be specially designed and constructed according to the specific conditions of chemical equipment. This not only increases the design cost and equipment cost, but is also not very versatile and has a limited application scope. In this case, if a non-contact, auxiliary universal cooling device can be designed, it is expected to reduce the design requirements of the water cooling system and achieve the purpose of collaborative work.
