Description

A liquid leakage alarm device for a plate heat exchanger

technical field

The utility model relates to a plate heat exchanger, in particular to a liquid leakage alarm device for the plate heat exchanger.

Background technique

The plate heat exchanger is a high-efficiency heat exchanger composed of a series of metal sheets with a certain corrugated shape. Thin rectangular channels are formed between various plates, and heat is exchanged through the plates. Plate heat exchanger is an ideal equipment for liquid-liquid and liquid-vapor heat exchange. It has the characteristics of high heat exchange efficiency, small heat loss, compact and lightweight structure, small footprint, wide application, long service life, high efficiency and energy saving, and convenient installation and disassembly. The plate heat exchanger plate is an independent component, and the process can be increased or decreased at will according to the requirements, and the forms are various; it can be applied to various different process requirements. The plate heat exchanger is clamped by clamping bolts. Therefore, it is easy to disassemble and assemble, and can be opened and cleaned at any time. At the same time, due to the smooth surface of the board and the high degree of turbulence, it is not easy to scale. Under the same pressure loss, the heat transfer coefficient is 3-5 times higher than that of the tubular heat exchanger, the floor area is one third of that of the tubular heat exchanger, and the heat recovery rate can be as high as 90% or more. The sealing groove of the plate heat exchanger is provided with a liquid leakage channel, and various media will not collude. Even if there is leakage, the media will always be discharged outwards.

Leaks and leaks occur when existing plate heat exchangers work. The main parts of external leakage are the seal between the plate and the plate, the second sealing leakage groove of the plate, and the inner side of the end plate and the compression plate. If the leakage occurs, if it is not repaired in time, it will affect the work of the plate heat exchanger.
