Problems solved by technology

It has the characteristics of high heat exchange efficiency, small heat loss, compact and light structure, small footprint, wide application, and long service life. However, the existing plate heat exchangers are prone to internal leakage after long-term use, which affects Thermal performance, in severe cases, it will cause adverse reactions such as corrosion, explosion or severe toxicity. The specific reasons for the internal leakage phenomenon are: due to the substandard water quality and improper operation of water treatment equipment, and the temperature difference between cold and hot media, it is easy to replace in the plate type. Scale (carbide, silica scale) is formed on the surface of the heater plate, which causes poor heat conduction, reduced heat transfer eff

Abstract

The invention relates to the technical field of plate heat exchangers, in particular to a leakage-proof synergistic plate heat exchanger which comprises a first plate, a second plate, a guide rod, a first plate piece, a first sealing assembly, an alarm device, a second plate piece and a second sealing assembly. According to the leakage-proof synergistic plate heat exchanger of the scheme, in orderto make a medium conveniently flow on the first plate piece, a corrugated structure is arranged on the first plate piece, the corrugated structure can increase the contact area of the medium and thefirst plate piece, meanwhile decrease the flowing speed of the medium on the first plate piece, and prolong the heat transfer time of the medium and the first plate piece, thereby improving the heat exchange efficiency.

Description

technical field [0001] The invention relates to the technical field of plate heat exchangers, in particular to a leak-proof and efficient plate heat exchanger. Background technique [0002] Introduction: 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 exchange is performed through the plates. Plate heat exchanger is an ideal equipment for liquid-liquid, liquid-vapor heat exchange. It has the characteristics of high heat exchange efficiency, small heat loss, compact and light structure, small footprint, wide application, and long service life. However, the existing plate heat exchangers are prone to internal leakage after long-term use, which affects Thermal performance, in severe cases, it will cause adverse reactions such as corrosion, explosion or severe toxicity. The specific reasons for the internal leakage phenomenon ...
