A plate condenser with liquid separation function

Abstract

The invention discloses a plate condenser with liquid separation function, which comprises a front compression plate, a rear compression plate and an intermediate heat exchange module, and the front compression plate and the rear compression plate are installed on two sides of the intermediate heat exchange module respectively. side; the intermediate heat exchange module is provided with a cooling water flow channel and a steam flow channel. The beneficial effects of the present invention are: timely liquid separation, removal of condensate, effectively reducing the thickness of the condensate liquid film, reducing the thermal resistance of condensation heat transfer, effectively improving the heat exchange effect of the plate condenser; no moving parts, low operating failure rate, High reliability; maintain the basic structural characteristics of conventional plate heat exchangers, inherit the advantages of conventional plate heat exchangers such as good compactness, small footprint, high heat transfer coefficient, and flexible assembly and use; The change law of the temperature curve in the condensation heat transfer process, the temperature and flow rate of the cooling fluid are configured separately, which makes the temperature matching relationship more reasonable, effectively reduces the heat transfer temperature difference, and reduces the heat transfer rate of the heat exchanger. loss.

Description

[0001] 【Technical field】 [0002] The invention relates to the field of condensers, in particular to a plate condenser capable of enhancing phase change heat transfer and being used for steam condensation with liquid separation function. [0003] 【Background technique】 [0004] The plate heat exchanger is composed of a series of parallel metal sheets with corrugated surfaces superimposed on each other. The space between the plates forms a channel for heat exchange fluid. The fluid transfers heat through the plates. The effective heat transfer area per unit volume Larger, it has the advantages of compact structure, high heat transfer coefficient, flexible assembly and convenient use. Plate heat exchangers are widely used in industries such as medicine, food and shipbuilding. In the above-mentioned industries, there are many heat exchanges between "liquid-liquid", and the advantages of plate heat exchangers are also obvious. For phase-change heat applications, such as refrigera...

Problems solved by technology

[0009] The purpose of the present invention is to overcome the shortcomings of the above-mentioned existing plate heat exchangers that cannot remove the condensate in time, which leads to the low condensation heat transfer coefficient of the plate condenser, and propose a plate condenser with a liquid separation function, which can condense the condensate in time through the liquid separation structure. Liquid removal can effectively reduce the liquid film thermal resistance of the plate condenser, thereby improving the heat transfer coefficient; at the same time, this structure can realize split-range condensation in the condensation process, can realize segmental condensation in the condensation process, reduce the heat transfer temperature difference, and reduce the heat transfer coefficient. heat loss
