Environmentally-friendly sound-absorbing natural gas pipeline filter device

Abstract

The invention discloses an environmentally-friendly sound-absorbing natural gas pipeline filter device. A gas inlet tube has an L-shaped shape, a gas outlet tube communicates with the inner chamber ofa valve body, a filter is mounted at a position, clinging to the right wall, at the inner side of the valve body, a filter element is mounted at the middle part of the inner side of the filter, the filter element is fixed to the top of the gas inlet tube through a filter element fixing rod, a positioning ring is arranged on the inner wall of the valve body, a gas-permeable net is fixed between the annular outer wall and the annular inner wall of the valve body, the bottom of a sucker is fixed to the top surface of the annular inner wall, a stepped hole is arranged in the bottom surface of theinner wall of the annular inner wall, a sealing ring is arranged in the stepped hole, the annular inner wall is sequentially covered with a moisture-proof sound absorbing layer, an anticorrosive sound absorbing layer, a shock absorbing layer and a damping layer, the moisture-proof sound absorbing layer is a honeycomb latticed structure made of foamed plastic, and the shock absorbing layer is a structure formed through clamping balloons by a double-layer spring. The device ensures the internal cleanness of the valve body to prevent damages and blockage of downstream pressure regulating devices, and has the advantages of high natural gas filtering efficiency, good sound-proofing, shock-absorbing and heat-preserving effects, and wide application range.

Description

technical field [0001] The invention belongs to the technical field of natural gas equipment, and in particular relates to an environmental-friendly and sound-absorbing natural gas pipeline filtering device. Background technique [0002] The pipelines that transport natural gas from mining sites or processing plants to urban gas distribution centers or industrial enterprise users are called natural gas pipelines, also known as gas transmission pipelines. The use of natural gas pipelines for natural gas transportation is the only way to transport large quantities of natural gas on land. [0003] If the lengths of all pipelines in the world are connected together, the length of natural gas pipelines accounts for about half of the total length, which shows the importance of natural gas pipelines in life and production. [0004] In the process of natural gas transportation, problems such as leakage and noise often occur, which cause great troubles to people. Long-term exposure...

Problems solved by technology

[0007] As my country's environmental pollution becomes more and more serious, more and more people choose to use clean energy. Natural gas has been widely used as a clean energy source. After natural gas is mined, it needs to be filtered with a filter, and the filtered natural gas is then sent to For users, the natural gas filter needs to be manually cleaned or replaced after a period of use. During replacement, the impurities and dust on the surface of the filter element will fall into the bottom of the valve body. Due to the narrow space of the valve body, it is difficult for the staff to move the valve body Clean up the dust and impurities at the bottom, then this part of the impurities will enter the downstream gas transmission pipeline with the natural gas, and then enter the pressure regulating valve and other equipment, which will easily cause blockage and damage to the downstream pressure regulating equipment. The cleaning of the pressure regulating equipment is very difficult. Trouble, the price of replacement parts is very high, and all natural filters in the prior art have this shortcoming, which needs to be solved urgently
