Abstract

The present invention relates to an improvement technique of heat exchanger, in the concrete, it is a plate type heat exchanger which does not produce water scale deposit and its water exchange mode. It is characterized by that in fixed tight-pressing plate side of general plate-type heat exchanger, the cold fluid inlet of upper portion of said fixed tight-pressing plate is connected with cold fluid backflow manifold by means of pipeline, the cold fluid outlet of lower portion of said fixed tight-pressing plate is connected with cold fluid discharge manifold by means of pipeline. Said invention adopts a downflow heat exchange mode, can make cold fluid and hot fluid be flowed from top to bottom in the plate-type heat exchanger, so that said invention utilizes the impact action of downwards-flowing fluid and gravity action of water scale granules self-body so as to implement the 'zero discharge' of said plate-type heat exchanger and on-tine 'automatic blowdown' function.

Description

Technical field

[0001] The invention relates to an improvement technology of a heat exchanger, in particular to a plate heat exchanger without scale deposition and a heat exchange method thereof. technical background

[0002] The plate heat exchanger is composed of a group of parallel thin plates, and the adjacent plates are separated by two pairs of special sealing gaskets to form channels. The cold and hot fluids flow in their respective channels at intervals. The plate heat exchanger The heat transfer coefficient is large, and the flow resistance is small. It is widely used in heating systems and food, medicine, chemical and other departments. According to the relative flow direction of the cooling and heating fluids in the heat exchanger, it can be divided into downstream type, countercurrent type, cross flow type, mixed flow type, etc., downstream type, that is, two fluids flow in parallel and in the same direction; countercurrent type, That is, two fluids flow in para...
