Make liquid, the gas-liquid mixture discharged by the gas outlet of water circulation vavuum pump returns again to water tank 7, form waterway circulating.Water circulation is true
Empty pump has many advantages, such as compared with other types of oil-sealed rotary pump：Its size simple in construction is small, and the rotating speed of pump is higher, pump with
Deceleration device need not can be installed between motor；Due to there is no metal friction surface in pump chamber, without to being lubricated in pump, and
And abrasion very little, the sealing between tumbler and fixture can complete directly by water seal；Pumping gas is uniform, and stable working can
Lean on, it is simple to operate, it is easy to maintenance；Because gas compression is isothermal in water circulation vavuum pump, therefore it can extract inflammable, explosive
Gas.Due to no air bleeding valve and friction surface, therefore the gas with dust, condensable gas and gas-liquid mixture can be extracted.
In addition, it is necessary to which it is emphasized that when collecting harmful influence liquid by principle of negative pressure, harmful influence liquid can be with gas-liquid
The form of two phase flow enters waste collection pipe 8, and because Action of Gravity Field liquid enters collection vessel 41, gas is through water circulation vavuum pump
Extract, compress and discharge pump chamber, because harmful influence gas can be dissolved in water, and have a certain amount of water in water circulation vavuum pump,
Therefore in the pump chamber of water circulation vavuum pump, because the rise of pressure make it that harmful influence gas is soluble in water, reduce harmful influence gas
The concentration of body, serves the effect for absorbing harmful influence gas, this is also the function that other vavuum pumps do not have.
There is certain density harmful influence gas in the gas of water circulation vavuum pump discharge, then by exhaust gas treatment unit to row
The gas gone out is handled.The exhaust gas treatment unit absorbs harmful influence gas using membrane absorption method, including, membrane module 32, branch
Support frame frame 34 and pipeline pump 33.
With reference to shown in Fig. 4, specifically, the membrane module 32 is mainly made up, and form gas of hollow fiber microporous membrane 323
Passage 321 and fluid passage 322, the gas passage 321 and fluid passage 322 are separated by microporous barrier 323, and the gas leads to
The inlet end in road 321 is connected by gas piping 31 with water tank gas outlet, and outlet side is connected with outside atmosphere.The support frame
34 are fixedly mounted in carriage body 1, are connected with membrane module 32, and for supporting membrane module 32, support frame 34 is preferred to use aluminium alloy
Profile material assembling is formed.
