Liquid removing device used outside water cooling type vertical condenser pipes

Abstract

The invention discloses a liquid removing device used outside water cooling type vertical condenser pipes. The liquid removing device is composed of the condenser pipes, liquid scraping devices, supporting frames, fixed pulleys, moving pulleys, pulley lines, suspension annular magnets, springs, suspension lines, a suspension water collecting basin, a thick pipeline, a siphon and a cooling water outlet. The outer wall faces of the annular magnets are in sliding contact with the inner wall faces of the condenser pipes, the lower ends of the springs are fixedly connected with the upper ends of the annular magnets, and the outer rings of the springs are slightly attached to the inner wall faces of the condenser pipes and are in sliding contact with the inner wall faces of the condenser pipes. The liquid scraping devices are located outside the condenser pipes, the inner wall faces of the liquid scraping devices are in sliding contact with the outer wall faces of the condenser pipes, the suspension water collecting basin is located below the condenser pipes and fixedly connected with hooks arranged at the lower portions of the moving pulleys through the suspension lines, and the siphon is located in the water collecting basin and fixedly connected with the bottom of the water collecting basin. Liquid film and liquid drops on the outer wall faces of the condenser pipes are scraped off through the liquid scraping devices automatically conducting reciprocating movement, and condensation thermal resistance outside the condenser pipes is reduced, so that condensing efficiency is improved.

Description

technical field [0001] The invention relates to a novel liquid removal device for water-cooled vertical condensing tubes, which is a device for enhancing heat transfer and phase change in a condenser. 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. [0003] Condensers can be divided into three categories: water-cooled, air-cooled, and evaporative according to their cooling media. Due to the large...
