With the continuous improvement of science and technology, more and more scientific instruments are being invented. Double tube plate heat exchangers are also constantly being manufactured. Double tube plate heat exchangers are a type of shell and tube heat exchanger, mainly used when two media cannot be mixed. So what is its principle?

Double tube plate heat exchanger is an energy-saving device that realizes heat exchange between materials, and it is widely used in various fields of the national economy. In production, in order to prevent corrosion and pollution, as well as meet the requirements of process flow, labor protection, safety production, etc., double tube plate heat exchangers are usually used to solve the problem.

At the end of the double tube plate heat exchange tube, there is a tube plate called the outer tube plate, also known as the tube side tube plate, which serves as the equipment flange and is connected to the heat exchange tube and the tube box flange. There is also a tube plate located closer to the end of the heat exchange tube, called the inner tube plate, which is the shell side tube plate, connected to the heat exchange tube and the shell side. There is a certain distance between the outer tube plate and the inner tube plate, which can be separated from the outside by a short section to form an isolation chamber that does not bear pressure; It can also be an open structure.

Application of Double Tube Plate Heat Exchanger

Double tube plate heat exchanger is a heat exchanger with two tube plates or equivalent to two tube plates with a certain gap at one end of the heat exchanger. In practical operation, double tube plate heat exchanger is generally used in the following two situations: one is to prevent the mixing of media between the shell and tube sides. For example, for heat exchangers with water flowing through the shell side and chlorine or chloride flowing through the tube side, if the water in the shell side comes into contact with chlorine or chloride in the tube side, strong corrosive hydrochloric acid or hypochlorous acid will be produced, which will cause serious corrosion to the material of the tube side.

With the use of double tube plate heat exchangers, the purpose of heat exchange has been achieved, which has improved the economy of various fields. It is a great technological machine.
