Environmental protection liquid ring vacuum pump

Liquid ring vacuum pump in environmental protection of application

Wastewater treatment
The liquid ring vacuum pump provides the extraction pressure needed to discharge wastewater and is used to clean the sewer network.

Methane gas compression
The liquid-ring vacuum pumps the methane from the top of the tank and recirculates it to improve the mixture and reaction rate. The working fluid of the vacuum pump cools the methane by absorbing compressed heat, providing an almost isothermal mode of operation, extending the service life of downstream valves, burners and motors, and reducing maintenance costs. Working fluid is also used as a fireproof device, reducing the explosion – proof cost. The contaminated gas is filtered through the water ring and partially dried. In this way, the gas is oxidized and returned to the wastewater treatment process.

Vacuum water
As a part of the vacuum water filling system, the liquid ring vacuum pump can reliably collect, transfer and treat the waste water in all areas through its use. Because of its high vacuum properties, the transfer of waste water is easy, even on the upside.

Biogas production
The number of microorganisms produced by the activated sludge tank and the sedimentation tank is stabilized in the sewage treatment tower to produce methane. Thorough mixing of sludge can increase gas production and shorten the time in the reactor. In this process, methane gas is pumped from the top of the tower, compressed in a double-ring compressor, and reintroduced through the mouth at the bottom.

Wastewater purification/activated sludge tank oxidation
In order to reduce the space requirements and reduce the cost of waste water treatment equipment, the number of activated sludge tank is increasing. Oxygen is extremely important for wastewater treatment. For small, dispersed or mobile equipment, air – ring fans are the most economical option.

At present, the main products of EVP vacuum pump factory are 2BV5, 2BV6, 2BE1, 2BE3, 2SK, SK series liquid ring vacuum pump/gas drainage pump, 2BW series liquid ring closed circulation system, JZJ2B, JZJ2S, JZJVV series plants and hospitals for oxygen supply ZF series vacuum negative pressure station, Siemens vacuum pump, mainly used in chemical, petrochemical, light industry, pharmaceutical, paper, metallurgy, building materials, electrical appliances, food, coal washing, mineral processing, chemical fertilizer and other industries, in many industrial production processes, such as: Vacuum filter, vacuum water diversion, vacuum feeding, vacuum evaporation, vacuum concentration, vacuum resurgence and vacuum degassing is widely used, because the liquid ring pump in the gas compression is isothermal, therefore, can smoke in addition to flammable and explosive gases (explosion-proof motor) can also take in addition to the dust, water, gas, when the vacuum pump body material to be able to bear or endure corrupt, can also vacuum pump is corrosive gases.
