Problems solved by technology

In these industrial fields, the vacuum water catch system (water catcher) used before has many shortcomings, which are mainly reflected in: ① When the water catcher is running without load, the gas conduction capacity is unchanged. After work, due to The wall of the condensation pipe at the inlet of the water trap first contacts the water vapor and forms ice or frost, which occupies the space for the pumped gas to pass through and affects the passage of the pumped gas, causing the condensation pipe at the back of the water trap to fail to collect. No or little water vapor is captured, resulting in low efficiency of capturing water vapor, wasting energy, making the structure of the water trap huge, wasting metal materials, and occupying a large area; Frost, frosting and icing have different effects. Frost has a low density and poor thermal conductivity, which affects the capture of water vapor. Ice has a high density and good thermal conductivity. In the case of the same capture area, it can More water vapor is captured, which improves the collection efficiency of the water catcher; ③ The defrosting methods mainly include water flooding and spraying. The watering method consumes a lot of water, defrosting is slow, and takes a long time; There are two types, hot water spray and steam spray, both methods require a heat source, resulting in energy waste

Abstract

The invention discloses a conduction-variable vacuum water catching device and belongs to the technical field of vacuum water catching. The vacuum water catching device comprises a water catcher, a refrigerating system and an auxiliary unit; a condenser tube shortens gradually in length in the direction from the gas inlet to the gas outlet, so that the conduction capacity of the water catcher varies from large to small when gas flows in the water catcher; a casing adopts a modified taper, and circular and round baffle plates are adopted for the inside of the taper casing, therefore the conduction capacity of the water catcher also varies from large to small when the gas flows in the water catcher, moreover, the efficiency for catching steam is improved, and the refrigerating capacity consumption is reduced. As the device adopts cooling water circulation for defrosting or deicing, reuse of waste water as well as heat energy is achieved, and purposes of high efficiency, energy saving and emission reduction are achieved; the device is simple in structure, low in construction cost, convenience in use and maintenance, and large in application range, and can be used wherever the steam is required to be caught.

Description

Technical field [0001] The invention belongs to the technical field of vacuum water capture, and particularly relates to a variable conduction vacuum water capture device. Background technique [0002] In modern industry, there are many industrial fields that need to extract water vapor. For example: vacuum distillation can be used in vacuum metallurgy, petrochemical industry, seawater desalination, edible oil deodorization, decolorization, etc.; vacuum drying can be used in food processing, pharmaceutical production, new material development, etc.; vacuum pressure impregnation can be used in motors, transformers, capacitors The dipping paint and so on. In these industrial fields, the vacuum water trapping system (water trap) used before has many shortcomings, which are mainly reflected in: ①When the water trap is running at no load, the conduction capacity of the gas is unchanged. The condensing tube wall at the entrance of the water trap first comes into contact with water va...
