Horizontal tube shell liquid scraping condenser based on siphon principle

Abstract

The invention discloses a horizontal tube shell liquid scraping condenser based on the siphon principle. The horizontal tube shell liquid scraping condenser comprises a shell body, horizontal condensation tubes, a liquid scraping unit and a water receiving bucket. The liquid scraping unit is composed of a liquid scraping device, a driving magnet, a driven magnet and a pulley set. A siphon tube is arranged in the water receiving bucket, the device is based on the periodic water receiving and drainage principle of the siphon tube, the water receiving bucket is made to move periodically and vertically, the liquid scraping device outside the condensation tubes is driven by the pulley set, the driving magnet and the driven magnet to carry out the periodic liquid scraping operation, a condensate liquid film, liquid drops and adsorbed impurities on the outer surfaces of the condensation tubes are scraped, the heat transfer resistance of the condensation tubes is effectively reduced, and the heat transfer and condensation efficiency is increased.

Description

technical field [0001] The invention relates to a shell-and-tube horizontal wiper condenser based on the principle of siphon, which is an enhanced heat and mass transfer device used in the field of refrigeration technology, and can also be used in condenser equipment for various gases in the corresponding chemical industry. Background technique [0002] A condenser is a device that converts a gas or vapor into a liquid. Condensers are very important equipment in refrigeration, air-conditioning and chemical industries. Power plants use many condensers to condense the steam discharged from turbines; in refrigeration plants, condensers are used to condense refrigeration vapors such as ammonia and Freon. Condensers are used in the petrochemical industry to condense hydrocarbons and other chemical vapors. During distillation, the device that converts vapor into liquid is called a condenser. All condensers operate by removing heat from a gas or vapor. Condensers can be divided ...

AI Technical Summary

Problems solved by technology

[0004] In order to overcome the deficiencies of the existing shell-and-tube horizontal condenser, the existence of the condensate film outside the condenser tube weakens the condensation efficiency, and the adsorption of impurities on the outer wall of the condenser tube causes the heat transfer effect of the condenser tube to decrease. The shell-and-tube horizontal condenser uses an automatic reciprocating liquid scraping device to scrape off the liquid film, liquid droplets and adsorbed impurities on the outer wall of the condenser tube, so that the condensation thermal resistance outside the condenser tube is reduced, thereby improving the condensation efficiency
