DETAILED DESCRIPTION

[0023] In order to make the purpose, technical scheme and advantages of the utility model clearer, the technical scheme of the utility model will be described clearly and completely below. Obviously, the described embodiments are only some of the embodiments of the utility model, not all. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the scope protected by the utility model.

[0024] The specific embodiments of the utility model will be described below in combination with the drawings:

[0025] As Figures 1-6 shown, a natural gas filtering device comprises a tank body 1 and an air inlet pipe 2. One side of the tank body 1 is provided with an air vent 15, and the other side is provided with an air outlet 16. One end of the air inlet pipe 2 enters the tank body 1 through the air vent 15 and passes through a filtering assembly in the tank body 1 to the lower part of the tank body 1, and the other end is connected with an external air pipe through a flange. Natural gas enters the water below the water surface at the bottom of the tank body 1 for water washing, and most of the solid impurities are removed through water washing. The natural gas after preliminary impurity removal enters the inside of the tank body 1 and passes through the filtering assembly, and finally is discharged from the air outlet 16. The filtering assembly further removes the residual particles and moisture in the natural gas, so that the pure natural gas is discharged from the tank body 1.

[0026] A detachable top cover 11 is arranged at the top of the tank body 1, and the top cover 11 is connected with the tank body 1 through a flange. The detachable top cover 11 is convenient for maintaining or replacing the parts inside the tank body 1. A first rubber sleeve 151 is arranged at the air vent 15, and the first rubber sleeve 151 fills the gap between the air vent 15 and the air inlet pipe 2. The first rubber sleeve 151 can prevent the gas inside the tank body 1 from escaping from the gap between the air inlet pipe 2 and the air vent 15. One side of the bottom of the tank body 1 is provided with a water filling pipe 14, and the other side is provided with an overflow pipe 13. Valves are arranged on the water filling pipe 14 and the overflow pipe 13. A drain valve 121 is arranged on the drain port 12 of the bottom of the tank body 1. When the drain valve 121 is opened, the water accumulated at the bottom of the tank body 1 can be discharged, which is convenient for replacing the water inside the tank body 1 and maintaining the water washing effect of the natural gas. The water inside the tank body 1 is replaced through the water filling pipe 14. When water is filled, the valve on the overflow pipe 13 is opened to prevent the water level inside the tank body 1 from being too high. Before the inside of the tank body 1 is aerated, the valves on the overflow pipe 13 and the water filling pipe 14 are closed.

[0027] The filter assembly comprises a filter plate 17, a filler 18 and a compression ring 172. The filler 18 is arranged between the filter plate 17 and the compression ring 172. The filter plate 17 and the compression ring 172 are both provided with an array of through holes, and the filler 18 cannot pass through the through holes. The inner wall of the tank body 1 is provided with a convex ring 171 matched with the filter assembly, and the top surface of the convex ring 171 is in contact with the bottom surface of the filter plate 17. The detachable filter assembly facilitates replacement of the internal filler 18 and other components, thereby ensuring the filtering effect of the filter assembly. The filler 18 comprises an activated carbon layer 182 and a desiccant layer 181. The filter plate 17 is provided with the activated carbon layer 182, the activated carbon layer 182 is provided with the desiccant layer 181, and the desiccant layer 181 is provided with the compression ring 172. The activated carbon layer 182 can adsorb the particulate impurities contained in the natural gas, the desiccant 181 is responsible for absorbing moisture, and the compression ring 172 keeps the thickness of each region of the filler 18 consistent. The thickness of the activated carbon layer 182 is half of the thickness of the desiccant layer 181. The natural gas after water washing contains too much moisture, and therefore the water absorption capacity of the filler 18 is required to be high. The gas inlet pipe 2 penetrates through the filter plate 17 to the lower part of the tank body 1, and the gap between the filter plate 17 and the gas inlet pipe 2 is provided with a second rubber sleeve 173. The second rubber sleeve 173 can prevent the natural gas after water washing from directly passing through the gap between the filter plate 17 and the gas inlet pipe 2 to the upper part of the filter assembly.

[0028] The gas inlet pipe 2 comprises an L-shaped pipe 21 and an aeration disc 22. The L-shaped pipe 21 is provided with the aeration disc 22 at the end extending into the inside of the tank body 1, and the other end is connected with the external gas pipe through a flange. The aeration disc 22 is beneficial to forming dense and uniform bubbles of the natural gas below the liquid surface. The contact area between the natural gas and the water body is increased, and the water washing effect is improved.

[0029] The working principle of the specific embodiment of the utility model is as follows: the natural gas enters the liquid surface below the bottom of the tank body 1 along the gas inlet pipe 2. Through the action of water washing, most of the solid impurities in the natural gas are removed. The natural gas after water washing passes through the filter assembly, and the residual particulate impurities and moisture are removed, and finally discharged from the gas outlet to the tank body 1.
