Anticorrosive, anti-explosion and environment-friendly type liquid ring vacuum unit

Abstract

The invention relates to an anticorrosive, anti-explosion and environment-friendly type liquid ring vacuum unit. The main structure of the unit is composed of a liquid ring vacuum pump, a heat exchanger, a gas-liquid separator, a pipeline type filter, a point contact anti-explosion vacuum meter, an anti-explosion motor, a valve and a pipeline. Unit flow passage components are made of anticorrosive materials or are subjected to anticorrosive treatment. Anticorrosive electrical elements authenticated nationally are adopted, gas or gas-water mixtures which are flammable and combustible and have certain corrosivity can be pumped, and the unit is particularly suitable for industries of biological pharmacy, medical intermediates, fine chemicals, pesticides, alkali chemical engineering, fluorine chemical engineering and the like needing acquisition of vacuum environments. The anticorrosive, anti-explosion and environment-friendly type liquid ring vacuum unit can solve the problems that traditional equipment is large in water resource consumption, large in sewage discharge capacity and high in equipment failure rate; meanwhile, the unit can be used for pumping flammable and combustible and corrosive media, the environment is better protected, water resource consumption is reduced, the equipment failure rate is reduced, the safety accident risk is lowered, and extremely-large social and economic benefits are achieved.

Description

technical field [0001] The invention relates to a corrosion-resistant, explosion-proof and environment-friendly liquid ring vacuum unit, which is especially suitable for the environment where vacuum needs to be obtained in industries such as biopharmaceuticals, pharmaceutical intermediates, fine chemicals, pesticides, alkali chemicals, and fluorine chemicals. It has the characteristics of large water resource consumption, large sewage discharge and high equipment failure rate. It can also be used to extract flammable, explosive and corrosive media, which is beneficial to protect the environment, reduce water resource consumption, reduce equipment failure rate and safety accident risk, and has great potential. social and economic value. Background technique [0002] At present, in industries such as biopharmaceuticals, pharmaceutical intermediates, fine chemicals, pesticides, alkali chemicals, and fluorine chemicals, a vacuum environment is required. At the same time, the pum...

Problems solved by technology

In these industries, the medium in the pumping container is polluted and the temperature is high. Pollutants and heat enter the working fluid of the liquid ring vacuum pump, which increases the temperature of the working fluid of the liquid ring pump and reduces the ultimate vacuum of the liquid ring pump. At the same time, the temperature is too high If the liquid ring vacuum pump reaches the ultimate vacuum, cavitation will occur, resulting in damage to the pump body and impeller of the liquid ring pump. If the working fluid of the liquid ring pump is connected to the cooling water system of the factory, although it can effec
