The spiral pre-separation The shell 1 can be set as the outer wall surface of the spiral pre-separator 3 (the closed spiral guide vane 4 and the open spiral guide vane 5 are welded to the inside of the housing 1), or the spiral pre-separator can be installed The outer casing of the device 3 is fixed inside the casing 1.

[0028] The diameter of the upper end surface of the No. 1 inverted cone bottom opening baffle 13 of the gas purifier 11 is larger than the upper end surface diameter of the No. 2 inverted cone bottom opening baffle plate 15, and the cone top opening baffle plate of the gas purifier 11 The diameter of the lower end surface of 14 is slightly smaller than the inner diameter of the spiral pre-separator 3. The tapered top opening baffle 14 and the second inverted cone bottom opening baffle 15 of the gas purifier 11 are multiple pieces, which are installed in a staggered manner.

[0029] The working process of the present invention is as follows:

[0030] In the normal working process, the mixture composed of gas and liquid is sent to the feed port 2 through the external pipeline. The mixture enters the spiral pre-separator 3 and begins to make centrifugal movement around the closed spiral guide vane 4. Under the action, the dense liquid is thrown to the outer side wall of the spiral pre-separator 3, most of the gas is separated and flows against the inner side wall, and then flows into the open spiral guide vane 5, and the liquid continues downward under the action of centrifugal force and gravity Do a rotating flow, the remaining gas in the liquid will continue to be separated under the action of centrifugal force. The separated gas enters the separator cavity through the spiral adsorption filter 6, and the airflow is filtered out when it passes through the spiral adsorption filter 6. Most of the droplets in the airflow, the droplets agglomerate on the inner surface of the spiral adsorbent filter 6 and become larger. When reaching a certain level, the droplets flow out of the spiral adsorbent filter 6 under the impact of the airflow and gravity, and collect to Near the inner edge of the open spiral guide vane 5, it merges with the rotating liquid along the guide vane. When the liquid flows to the inverted cone centrifugal separation liquid collection chamber 7, the liquid carries a small amount of gas and performs tangential rotation centrifugal movement. The liquid continues to rotate in the inverted cone centrifugal separation liquid collection chamber 7 to reach the liquid outlet 8 and separate the remaining gas in the liquid.

[0031] The gas enters the separator chamber, and the gas carries a small part of the liquid droplets, and moves upward and hits the No. 2 inverted cone bottom opening baffle plate 15. Due to the large momentum of the gas flow droplets, it is not easy to change the flow direction, and the liquid droplets are captured on the baffle plate Above, the droplets condensate and become larger and flow to the inverted cone centrifugal separation sump 7 under the action of gravity. After several changes of direction, a large number of droplets in the airflow are captured, and finally the airflow is guided by the adsorbent filter 12 The air pipe 9 is discharged, and when the air flows through the absorbent filter flow 12, the liquid particles coalesce and grow on the inner surface of the filter element due to the coalescence function of the filter medium; when the droplets reach a certain size, they flow out of the filter due to the impact of gravity and air flow. Flow through the bottom openings of the No. 1 inverted cone bottom opening baffle 13 and the No. 2 inverted cone bottom opening baffle 15 to the inverted cone centrifugal separation liquid collection chamber 7, and the No. 2 inverted cone bottom opening baffle 15 The porous medium baffle plate 17 in the bottom opening has two functions. One is to prevent the air flow from short-circuiting the baffle plate to directly move upward, and the other is that the captured droplets can flow to the inverted cone through the porous medium baffle plate 17 under the action of gravity. Shape centrifugal separation liquid collection chamber 7.

[0032] It should be noted here that the number of the cone-shaped top opening baffle 14 and the second inverted cone bottom opening baffle 15 of the present invention, and the number of cycles of the closed spiral guide vane 4 and the open spiral guide vane 5 It can be determined according to needs, which should be known to those skilled in the art, and will not be repeated here.
