To sum up, the working principle is as follows:
The first flange plate 9 is connected with a discharge pipe of natural gas exploitation equipment through a metal hose, and the vibration plate 2 below the tank body 1 is opened. Natural gas enters the first one-way valve 7 through the first pipeline 8, and the input end of the first one-way valve 7 is close to the first pipeline 8. Natural gas reaches the first flexible straight-through 6 through the first one-way valve 7, and the rubber part arranged in the first flexible straight-through 6 can buffer part of power generated by the vibration disc 2 of the tank body 1. Natural gas is fed into the tank 1 through a first flexible feed-through 6 into the inlet pipe 5.
Reaching the baffle plate 3, most natural gas can diffuse to the periphery and pass through the filtering holes 4 due to the funnel-shaped design of the baffle plate 3, and the small part passes through the middle. Because the density of the sediment is larger than that of the natural gas, the sediment can be precipitated, and part of the sediment also flows along with the dynamic force of the natural gas flow, the flow direction of the natural gas is broken by using the vibration disc 2 to vibrate, so that the natural gas can flow irregularly, and sediment precipitation is quickened. A plurality of baffles 3 are arranged in the tank body 1, and the diameter size arrangement of the filtering holes 4 on the baffles 3 is gradually reduced from the air inlet pipe 5 to the air outlet pipe 10. Sequential filtering may be implemented.
After the natural gas is filtered, the natural gas flows out from the gas outlet pipe 10 to reach the second flexible straight-through 11. The second flexible through 11 is also a power for damping the vibrations of the vibration plate 2. Natural gas passes through the second flexible through 11 to the second non-return valve 12, the input end of the second non-return valve 12 being close to the second flexible through 11. The natural gas passes through the second one-way valve 12 to reach the second pipeline 13, and the second flange 14 is connected with the existing natural gas exploitation sand remover through a metal hose, and the working principle of the existing sand remover is based on the centrifugal sedimentation and density difference principle . Make natural gas carry out the filtration of first step through this novel device earlier, filter most silt. The load of the existing sand remover is reduced, and the service life is prolonged. Meanwhile, the sand remover does not need to filter too much sediment, so that the sand removal speed is increased, and the yield of the finished natural gas is improved.
The cleaning mechanism comprises a process that the third flange plate 20 is connected with the output end of a water pump through a hose to pump purified water, the purified water reaches the third one-way valve 16 through a third pipeline 25, and the input end of the third one-way valve 16 is close to the third pipeline 25. Purified water flows into the water inlet pipe 15 through the third one-way valve 16 and then reaches the tank body 1, and sand is flushed reversely from the direction of natural gas. A liquid level sensor is arranged in the tank body 1, and when purified water reaches one third of the tank body 1, the first valve 19 is opened, and the water after being cleaned is discharged from the water outlet pipe 18. Until the water drain becomes clear, the pump is turned off. The first valve 19 is closed when the water level has just been displaced over the outlet pipe 18, in preparation for the next filtration of natural gas.
Since the density of the residual natural gas is not as high as that of the purified water, the natural gas can be accumulated on the inner side of the tank body 1, and the residual natural gas can enter the first pipeline 8 through the return pipe 21, the fourth one-way valve 23 and the fourth pipeline 24 after the second valve 22 is opened. When the water in the tank body 1 reaches the return pipe 21, the second valve 22 is closed, and as the pressure ratio of the purified water in the tank body 1 is larger, the purified water can only flow to the first flexible straight-through 6, but as the purified water does not flow to the first pipeline 8 due to the arrangement of the first one-way valve 7, the natural gas flowing back in the first pipeline 8 does not flow into the tank body 1 due to the pressure difference, and when the natural gas is filtered next time, the pressure in the tank body 1 is reduced due to the fact that the purified water in the tank body 1 is emptied, and the natural gas flowing back before can pass through the first one-way valve 7. The purpose of reducing natural gas waste is achieved.
It is worth supplementing that the flexible straight-through is a pipeline connecting piece, is mainly used in a pipeline system, and allows the pipeline to displace or deform to a certain extent when being subjected to external load, so that the stress is absorbed or relieved, and the pipeline is suitable for various external environment changes. The flexible through is usually made of flexible material, such as rubber, plastic, etc., with good elasticity and sealing properties.
Although embodiments of the present utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the utility model, the scope of which is defined in the appended claims and their equivalents.
