The Requirements To Be Followed In The Design Of Plate Heat Exchanger

The plate heat exchanger is a detachable heat exchange device composed of many corrugated heat transfer plates, which The requirements to be followed in the design of plate heat exchangerare compressed by rubber gaskets at certain intervals. The plate heat exchanger has an irreplaceable role, so its design also has certain requirements.

(1) Small temperature difference. Since the plate heat exchanger has a high heat transfer coefficient and strong turbulence, the temperature difference between one or two hot water heat exchangers is small, and the heat exchanger heating and temperature difference in the heat exchanger can reach 1 to 3 degrees. It can greatly improve the economy of the heat exchanger and will be improved.

(2) Small heat loss. Since the edges of the steel plate and the surrounding gaskets are exposed to the atmosphere, the heat loss is small (about 1%), so there is no need to take heat preservation measures. Under the same heat exchange area, the heat loss of the plate heat exchanger is only 1%.

(3) Strong adaptability. When the heat transfer plate of the heat exchanger is assembled, it is easy to increase or decrease the weight in combination with the plate can be rearranged and flowed according to the requirements of production and process. The adaptability of plate heat exchangers has also been widely used. It is widely used in chemical engineering, machinery, cement, petroleum, electric power, hot water heating and other engineering fields. It is used for heating, cooling, evaporation, condensation, heat recovery and other processes through plate heat transfer.

(4) Flexible operation and convenient maintenance. Both the heat transfer plate and the movable pressing plate are suspended on the beam of the plate heat exchanger. The rolling device is installed on the top of the pressing plate. Open the equipment, clean, take out the printing plate, check or replace the gasket, easy to use.
