Heat exchange plate used for plate type heat exchanger

Abstract

The invention relates to the field of heat exchange equipment, in particular to a heat exchange plate and application thereof. The adopted technical scheme is that the heat exchange plate of a plate type heat exchanger is characterized by comprising a plate body, wherein the plate body is provided with a pit and a turbulent flow strengthening concave groove. Compared with the prior art, the heat exchange plate has the following advantages and effects that: a heat exchanger comprising the heat exchange plate generates high turbulent flows by using internal fluid of a heat transfer plate, has very high heat transfer efficiency, and has small pressure loss compared with a common plate type heat exchanger; the heat exchange plate has a simple structure, is convenient to process, and is flexible to mount; the heat exchange plate has wide application fields, is suitable for the heat transfer processes such as liquid-liquid heat transfer, gas-liquid heat transfer, gas-solid (powder) heat transfer, liquid-solid (powder) heat transfer and the like, and is particularly suitable for the heat exchange technological process of fluid and powder; and the heat exchange plate has a large application pressure range, and can be suitable for occasions with high, middle, low pressure and negative pressure.

Description

Technical field [0001] The invention relates to the field of heat exchange equipment, in particular to a heat exchange plate and its application. Background technique [0002] Plate heat exchanger is a kind of high-efficiency heat exchange equipment, which is widely used in petroleum, chemical industry, metallurgy, machinery, light industry, food, medicine, refrigeration, heating and other industries. The plate heat exchanger has the characteristics of high heat transfer efficiency, small size, and convenient layout. The plate heat exchanger is a detachable heat exchange device composed of many corrugated (or other protrusions) heat transfer plates pressed together by gaskets at certain intervals. The through holes on the heat transfer plates are connected together to form a fluid Runners, inter-plate channels are formed between the plates. The heat exchange plate of this heat exchanger has the disadvantages of complex structure, high processing cost, difficult cleaning, l...

AI Technical Summary

Problems solved by technology

The heat exchange plate of this heat exchanger has the disadvantages of complex structure, high processing cost, difficult cleaning, large flow resistance and pressure loss; the heat exchanger with this structure is mainly used for heat exchange between liquids, and it is difficult to It is used for heat exchange process requirements between gas condensation or viscous liquid, fluid and solid (powder)
