[0025] The utility model is further described below in conjunction with the accompanying drawings:

[0026] like Figure 1 — Figure 6As shown, a gas-water separator for natural gas production includes a base 101, a connecting assembly is arranged on the base 101, a separating mechanism is fixedly connected to the connecting assembly, the separating mechanism includes a separating shell 201, a screening mechanism is installed in the base 101, a collecting mechanism is arranged in the base 101, the screening mechanism includes a rotating ring 301, the rotating ring 301 is rotatably connected to the top of the base 101, a filter screen 302 arranged in a cone is connected in the rotating ring 301 by bolts, the collecting mechanism includes a scraper 401, the scraper 401 is welded to the inner wall at the bottom of the separating shell 201, the scraper 401 is attached to the upper surface of the filter screen 302, the scraper 401 is used to clean the solid particles on the filter screen 302, the scraper 401 is arranged obliquely, when the separated water passes through the filter screen 302, the solid impurities remain on the filter screen 302, and will accumulate and clog the filter screen 302 when used for a long time, the arrangement of the scraper 401 can continuously clean the solid particles on the filter screen 302, thereby ensuring the separation effect of water and impurities.

[0027] In this embodiment, a drop rod 402 is welded to one side of the scraper 401, and the drop rod 402 is set obliquely. A material guide channel 403 is set in the drop rod 402, and a lead-out pipe 404 is glued to the end of the material guide channel 403. The bottom of the filter 302 is connected to the rotating seat 303 by bolts, and a feed port 304 is opened in the rotating seat 303. The lead-out pipe 404 leads to the position of the feed port 304. The solid particles scraped off by the scraper 401 will rush into the material guide channel 403 in the drop rod 402 due to the effect of inertia, slide into the lead-out pipe 404 through the material guide channel 403, and the lead-out pipe 404 guides to the position of the feed port 304, thereby collecting the solid particles.

[0028] In this embodiment, the connecting assembly includes a fixed disk 102, a plurality of connecting columns 103 are connected to the top of the fixed disk 102 by bolts, a connecting disk 104 is connected to the top of the connecting column 103 by bolts, and the separation shell 201 is connected to the inner side of the connecting disk 104 by bolts. The connecting assembly fixes the base 101 and the separation shell 201 to ensure the stability of the rotating ring 301 during rotation.

[0029] In this embodiment, a water blocking cover 305 is bolted to the top of the rotating seat 303 to block water from entering the feed port 304. The water blocking cover 305 is configured to prevent separated water from directly entering the feed port 304, thereby ensuring that the water flows downward from the filter screen 302.

[0030] In this embodiment, the collecting mechanism includes a collecting barrel 405, which is connected to the bottom of the base 101 by bolts. The collecting barrel 405 is rotatably connected to the bottom of the rotating seat 303. The feed port 304 leads to the collecting barrel 405. The bottom of the collecting barrel 405 is detachably connected to a bottom cover 406. The bottom cover 406 and the collecting barrel 405 are connected by threads. Solid impurities enter the feed port 304 from the lead-out pipe 404 and finally fall into the collecting barrel 405. The bottom cover 406 is rotated to unscrew the solid impurities in time.

[0031] In this embodiment, a gear ring 306 is welded to the outside of the rotating ring 301, and the screening mechanism includes a motor 307. The motor 307 is connected to the top of the fixed disk 102 by bolts, and the output end of the motor 307 is connected to a gear 308 meshing with the gear ring 306 by bolts. When the motor 307 is started, the motor 307 drives the gear 308 to rotate, the gear 308 drives the gear ring 306 to rotate, and the gear ring 306 drives the rotating ring 301 to rotate.

[0032] In this embodiment, an air inlet pipe 202 is welded to one side of the bottom of the separation shell 201, a gas-liquid cyclone separator 203 is installed inside the separation shell 201, an air outlet pipe 204 is welded to the top of the separation shell 201, and a water outlet pipe 105 is welded to the bottom of the base 101.

[0033] Working principle: When the device is in use, the gas-liquid cyclone separator 203 and the motor 307 are first turned on, and the extracted natural gas is introduced into the device from the inlet pipe 202. After the separation effect of the gas-liquid cyclone separator 203, the gas is led to the upper outlet pipe 204, and the separated liquid falls to the filter 302 below. The motor 307 drives the gear 308 to rotate, the gear 308 drives the gear ring 306 to rotate, and the gear ring 306 drives the rotating ring 301 to rotate. The rotating ring 301 drives the filter 302 and the rotating seat 303 to rotate. When the separated water falls on the filter 302, due to the centrifugal effect of the rotation of the filter 302, the water is thrown out of the filter 302 and falls. The solid impurities in the water are retained on the filter screen 302, and the filter screen 302 rotates to drive the solid impurities to move. When the solid impurities move to the scraper 401, the scraper 401 scrapes them off. The solid particles scraped off by the scraper 401 will rush into the guide channel 403 in the drop rod 402 due to inertia, slide into the outlet pipe 404 through the guide channel 403, and guide the outlet pipe 404 to the feed port 304. The solid impurities enter the feed port 304 from the outlet pipe 404 and finally fall into the collecting barrel 405. The bottom cover 406 is rotated and unscrewed to discharge the solid impurities in time, thereby collecting the solid particles.

Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principles of the utility model.
