vacuum pump waste gas treatment

The vacuum pump in the factory will volatilize part of the waste gas. In fact, the vacuum pump itself will not produce waste gas. The waste gas discharged by the vacuum pump is mainly the gas composition used in the working system. How to treat this part of waste gas? In fact, the simple and direct way with less investment is to use carbon adsorption to collect, purify and discharge the waste gas. The adsorption characteristics of the active carbon can be used In order to adsorb harmful components to the gas, so as to achieve a good effect of air purification, let you know about the two ways of vacuum pump waste gas treatment.


The waste gas produced by vacuum pump is not single in composition. The two processes can make the organic waste gas purified by equipment after collection, and then discharged into the atmosphere through a 15 meter chimney.


1. Carbon adsorption method: mainly composed of active carbon layer and supporting layer. Activated carbon has developed pores, large specific surface area and high adsorption capacity. It is precisely because of this characteristic of activated carbon, it is widely used in the advanced treatment of water, such as domestic water supply, the advanced treatment of the sewage after (clean water) and so on After using the activated carbon for a period of time, a large amount of adsorbate has been adsorbed, which gradually tends to be saturated and loses its working ability. In serious cases, it will penetrate the filter layer, so the regeneration or replacement of the activated carbon should be carried out.

2. Ion purification method: a high-pressure generator is used to form a low-temperature plasma. Under the action of a large number of electrons with an average energy of about 5ev, the organic waste gas molecules such as benzene, toluene and xylene through the purifier are converted into various active particles, which are combined with O2 in the air to generate low-molecular harmless substances such as H2O and CO2, so as to purify the waste gas. During the treatment, when the organic gas enters the cold ionomer reaction chamber, the gas is evenly distributed to the plasma reaction chamber (PRC). The reaction chamber is divided into 149 hexagonal tubes, each of which is separated from the reaction chamber by a coronary wire in the center.


The high voltage can be adjusted by conducting the high voltage wire to the reaction chamber, and the high voltage is conducted to the tubular wire in the pipe. There is a discharge phenomenon from the wire to the pipe wall. Once discharged, the plasma electrons collide with the gas molecules to produce chemically active nuclides, which are usually called radical and loaded carriers. In addition, the utility model has the function of a micro electrostatic precipitator, which can remove dust.


This paper introduces two ways of vacuum pump waste gas treatment, in fact, there are many ways, mainly the collection of vacuum pump waste gas pipeline. It is necessary to design the main pipe diameter, branch pipe diameter, etc., and then use the side suction or up suction to collect, and choose how much air volume and air pressure fan to use, which determine the purification effect, such as If you have any questions about the use of vacuum pump, please contact us.
