Abstract
The invention discloses a gas purifier, which comprises a separation tank, a gas inlet pipe, a gas outlet pipe and a blowdown pipe. The separation tank is divided into an upper chamber and a lower chamber by a separation plate, wherein the upper chamber communicates with the gas outlet pipe. The lower chamber is separately equipped with a safety valve, the blowdown pipe, a liquid-level meter and a pressure measuring device, wherein the blowdown pipe is externally connected to a blowdown device. Through holes are arranged in the separation plate. A filter is disposed on the upper part of the separation plate. A circular pipe is connected to the lower part of the separation plate. The upper part of the circular pipe is hermetically coupled to the separation plate, and the lower part of the circular pipe is open. A separation circular pipe is hung in the circular pipe. The gas inlet pipe is tangentially inserted into the separation circular pipe. Gas enters the purifier and goes through three processes of hydrocyclone separation, elbow pipe separation, and filter separation. According to the invention, the gas purifier has advantages of impact structure, high separation efficiency and low maintenance efficiency.
Description
Technical field
The present invention relates to a kind of air cleaning unit, especially a kind of gas cleaning plant for removing Oil in circulating gas water and solid particle polluter.
Background technology
In pressurized gas system, gas in system contains a lot of impurity, these impurity are oil, water and some solid particle polluters mainly, if do not process it and directly use, the impurity carried in gas will cause very large harm to the element in system, make the maintenance cost of equipment and maintenance frequency greatly increase, scrapping of equipment in gas system time serious, can be caused.Conventional gas purifying equipment comprises: cyclone and filter.When adopting cyclone to purify Compressed Gas, if after compressed air enters knockout drum, the inwall of knockout drum directly carries out cyclonic separation, the impurity of Lower separator likely can purge again and bring outlet line into by the gas then rotated, and the draw ratio of knockout drum all requires higher, then more difficult with in Design of length at the diameter of knockout drum, cause knockout drum bulky possibly; If reduce the volume of knockout drum, then its separative efficiency can decline again.When adopting filter to carry out gas purification, because in gas, impurity is more, being easy to cause filter blocks, needing to regularly replace filter core, wasting time and energy.
Summary of the invention
Object of the present invention is exactly for prior art Problems existing, provides that a kind of compact conformation, separative efficiency are high, maintenance frequency is low, reaches the gas cleaning plant that Compressed Gas uses standard.
For achieving the above object, the present invention adopts following design:
A kind of gas cleaning plant comprises knockout drum, gas inlet/outlet pipe and blow-off pipe, and wherein: described knockout drum is divided into upper and lower two chambers by dividing plate, and upper chamber is communicated with gas outlet tube, lower chamber is mounting safety valve, blow-off pipe respectively; Dividing plate is processed with through hole, and in top mounting filter, the lower partition connects a pipe, and top and the dividing plate of pipe are tightly connected, the lower openings of pipe; Hang installation one in pipe and be separated pipe; Gas inlet tube tangentially inserts separation pipe from the lower chamber of knockout drum.
Such scheme comprises further:
Described separation pipe top is cylindrical, and bottom is tapered.
The lower chamber external liquid level meter of knockout drum and device for pressure measurement.
At blow-off pipe external pollution discharging device.
The bottom of described knockout drum is hemispherical or taper; The pipe that described the lower partition connects is processed into truncated cone-shaped.
Advantage of the present invention is: after (1) gas enters separator tube, gas and magazins' layout, removing impurities falls into separator tube bottom, divided gas flow enters separator tube and outer pipe annular space from separator tube top, then filter interior is risen to after turning from annular space bottom, outer pipe is equivalent to the length adding separator tube upper gas section, thus decreases the axial length of separator tube, and it is compact that structure becomes; (2) divided gas flow rises to filter interior after turning from annular space bottom, and turning is herein equivalent to an elbow separator, has carried out second time be separated gas and impurity, further reduces profit and solid impurity amount that uprising gas carries; (3) use of filter further ensures the quality of Purge gas, and separator tube and its outer pipe are to the primary purification of gas, reduce the amount of impurities entering filter, ensure that the life cycle of filter.
