Natural gas filter

Abstract

The invention discloses a natural gas filter which forms an arc-shaped gas flow pipeline through a rotating ball, is matched with multiple layers of baffles which are distributed in an up-and-down staggered manner to prolong the passing path of natural gas and can preheat the natural gas, and is characterized in that flange plates are fixedly arranged at the two ends of a filter cartridge respectively; a heating cylinder is fixedly connected with one of the flange plates, a plurality of heating pipes which are distributed at equal intervals are arranged in the heating cylinder, the two ends ofeach heating pipe are fixedly connected with the heating cylinder through screws respectively, two sets of baffles are arranged in the filter cartridge, the two sets of baffles are arranged at the bottom and the top of the filter cartridge respectively, and fixing blocks are arranged on the baffles. The fixed blocks are inserted into the inner wall of the filter cartridge, clamping teeth are arranged on the fixed blocks, the baffles are circular plates with a notch, a plurality of moisture absorption holes are formed in the baffles, the moisture absorption holes are spherical holes, a spherical cavity is formed in each moisture absorption hole, and a rotating ball is rotatably arranged in the spherical cavity.

Description

technical field [0001] The invention relates to a natural gas filter, which relates to a filter for filtering domestic natural gas and belongs to the field of natural gas equipment. In particular, it relates to a filter that can preheat the natural gas by forming an arc-shaped air flow pipe by rotating the ball and coordinating with multi-layer baffles distributed up and down to extend the passing path of the natural gas. Background technique [0002] Pipeline transportation is the main form of natural gas transportation. At present, when natural gas passes through the pipeline, a certain amount of moisture will accumulate in the pipeline due to long-term dark conditions. The purity of natural gas is not enough, so that when it is burned at home, the moisture in the natural gas will react with the sulfur in the natural gas to form hydrogen sulfide, and hydrogen sulfide is very corrosive to metals, and now natural gas pipelines are mostly metal pipelines.

[0002] Pipeline transportation is the main form of natural gas transportation. At present, when natural gas passes through the pipeline, a certain amount of moisture will accumulate in the pipeline due to long-term dark conditions. The purity of natural gas is not enough, so that when it is burned at home, the moisture in the natural gas will react with the sulfur in the natural gas to form hydrogen sulfide, and hydrogen sulfide is very corrosive to metals, and now natural gas pipelines are mostly metal pipelines. It will cause corrosion to the pipeline, damage the pipe wall, seriously cause pipeline leakage, and cause safety problems. The dehumidification method in the existing natural gas pipeline is usually to add water-absorbent pads to dehumidify the gas, but this dehumidification method is due to the natural gas passing through. The path is short, resulting in a small contact area with moisture, resulting in poor dehumidification effect

[0003] Notification number CN209243015U discloses a natural gas filtering device, including a filter cartridge, the top of the filter cartridge is provided with a filter chamber, the top of the filter cartridge is fixedly equipped with a sealing cover, and one side of the filter cartridge is fixedly installed with an air outlet pipe. The filter chambers are connected, the bottom of the filter cartridge is fixedly installed with an air inlet pipe, the top of the air inlet pipe extends into the filter chamber, the inner wall of the filter chamber is fixedly installed with a first annular plate, and the top of the first annular plate is provided with a first through hole , the top of the first annular plate is fixedly installed with water-absorbing sponge felt, and the filter plate above the water-absorbing sponge felt is slidably installed in the filter cavity, and the top of the filter plate is fixedly installed with installation holes. The device has only one layer of water-absorbing sponge , and the passing path is short, the water filtration is not sufficient
