Plate type condenser with automatic liquid removing function

Abstract

The invention discloses a plate type condenser with an automatic liquid removing function. The plate type condenser comprises cooling water layers, condensation gas layers, condensation wall faces, liquid scraping devices, pulley blocks, magnets, hanging water collection tanks, siphon pipes and S-shaped plane springs. A condensation gas inlet of the condenser is located in the top of the rear side of the condenser. Condensation gas is condensed into liquid on the wall faces in the condensation gas layers, and the liquid flows into a condensation liquid communication passageway, and then flows out of a condensation liquid outlet. Cooling water enters the condenser from the top and flows downward into the hanging water collection tanks along the cooling water layers. The cooling water of the hanging water collection tanks is periodically collected and drained through the siphons, so that the hanging water collection tanks are made to periodically move up and down, the liquid scraping devices and the S-shaped plane springs are driven by the pulley blocks and the magnets to move up and down in a reciprocating mode so as to scrape away condensation liquid film on condensation wall faces, and therefore heat transfer resistance of condensation plates can be effectively reduced, heat transfer efficiency and condensation efficiency can be improved, impurities in cooling water can be prevented from scaling on the wall faces of the cooling water layers, and the continuous working period of the condenser can be prolonged.

Description

technical field [0001] The invention relates to a novel plate condenser with automatic liquid removal function, which is a device for enhancing heat transfer and phase change. Background technique [0002] A condenser is a device that converts a gas or vapor into a liquid. Condensers can be divided into three categories: water-cooled, air-cooled, and evaporative according to their cooling media. Due to the high heat transfer coefficient and compact equipment, the plate condenser has important applications in refrigeration, air conditioning and chemical industries. [0003] During the working process of the condenser, the vapor condenses on the condensation wall. Since the thermal conductivity of the condensate is low, the key to enhancing the condensation heat transfer is to reduce the thickness of the condensate film. Film condensation is a type of condensation process. The characteristic is that the condensate can form a liquid film and completely wet the wall surface o...
