How much do you know about the reactor condenser?

A lot of things have been said in the front of the reactor, and everyone has already known about it, but as a main reaction equipment, the reactor is usually equipped with some condensers , water separation columns, vacuum systems and others when stirring the reaction production. Condenser, according to the cooling medium can be summarized into four categories, its role is as follows:
1. Water-cooled:
In this type of condenser, the heat released by the refrigerant is taken away by the cooling water. The cooling water can be used once or recycled. Water-cooled condensers can be divided into vertical shell and tube types according to their different structural types. Horizontal shell and tube type and sleeve type.
2. Water-air cooling:
In this type of condenser, the refrigerant is cooled by water and air at the same time, but it mainly relies on the evaporation of the cooling water on the surface of the heat transfer tube, and absorbs a large amount of heat from the refrigerant side as the latent heat of vaporization. The role of air is mainly It is to take away water vapor to accelerate the evaporation of water. Therefore, this type of condenser consumes very little water. It is the preferred type of condenser for areas with dry air, low water quality, and low water temperature. This type of condenser can be divided into two types, evaporative type and irrigating type, according to their structural types.
3. Evaporation-condensation:
In this type of condenser, the cold effect generated by the evaporation of the refrigerant in another refrigeration system is used to cool the refrigerant vapor on the other side of the heat transfer partition, which promotes the latter to condense and liquefy. Such as the evaporator-condenser in the cascade refrigerator. Working principle: When the refrigerant enters the evaporator, the pressure decreases and it changes from a high-pressure gas to a low-pressure gas. This process needs to absorb heat, so the surface temperature of the evaporator is very low, and the cold air can be blown out by a fan. The condenser is a high-pressure, high-temperature refrigerant coming out of the compressor, which is cooled to a high pressure and a low temperature. It is then gasified by a capillary tube and evaporated in the evaporator.
A heat exchanger is a device that transfers part of the heat of a hot fluid to a cold fluid, also known as a heat exchanger. The heat exchanger is an indispensable device to realize heat exchange and transfer in the chemical production process. In the heat exchange, there are often some corrosive and oxidizing materials. Therefore, the materials used to make the heat exchanger are required to have strong corrosion resistance.
