A fully welded plate heat exchanger is a universal heat exchange device that uses metal plates with a certain corrugated shape as the heat transfer surface, and the metal plates are sealed by welding between them. This type of heat exchanger is efficient and compact, suitable for applications such as liquid-liquid heat exchange, liquid steam heat exchange, gas gas heat exchange, etc. It is a device for water water, water steam, water oil, and gas heat exchange.

The fully welded plate heat exchanger uses metal corrugated plates as heat transfer elements and adopts welding technology for sealing, greatly improving the safety and reliability of the heat exchanger. It has the characteristics of high heat transfer coefficient, pressure reduction, and small footprint, and is an efficient heat exchange equipment. Especially for fully welded plate heat exchangers used in gas to gas heat exchange, they have the advantages of high heat transfer efficiency, good sealing performance, pressure reduction, compact structure, corrosion resistance, long service life, low dust accumulation, and easy cleaning. Currently, gas gas fully welded plate heat exchangers are increasingly used for preheating combustion air and gas in various industrial furnaces.

 

Application fields of fully welded plate heat exchangers

The fully welded plate heat exchanger is a universal heat exchange equipment suitable for various liquid liquid heat exchange, liquid steam heat exchange, gas gas heat exchange and other occasions. It is an ideal equipment for water water, water steam, water oil, gas gas heat exchange, and is applied in fields such as petroleum, chemical, power, metallurgy, and food.

(1) Water water heat exchange: used for heating or cooling industrial or domestic water, such as central heating, domestic hot water, circulating water cooling, etc;

(2) Water oil heat exchange: used for heating or cooling industrial oils, such as hydraulic oil cooling, quenching oil cooling, engine oil cooling, etc;

(3) Water steam heat exchange: used for heating industrial or domestic water or condensing steam, such as process water heating, circulating water heating, etc;

(4) Gas gas heat exchange: used for the recovery of waste heat from various industrial furnace flue gases, such as air preheaters, gas preheaters, etc.
