Technical Field

[0001] The utility model relates to the technical field of natural gas drying filters, and particularly relates to an anti-clogging natural gas drying filter. Background Technique

[0002] Natural gas refers to all gases that exist naturally in nature, including gases formed by various natural processes in the atmosphere, hydrosphere, and lithosphere. The long-term common definition of "natural gas" is a narrow definition from the perspective of energy, which refers to a mixture of hydrocarbon and non-hydrocarbon gases naturally stored in strata. In petroleum geology, it usually refers to oilfield gas and gas field gas. Its composition is mainly hydrocarbon and contains non-hydrocarbon gases. The main use of natural gas is as a fuel, which can be used to manufacture carbon black, chemical drugs, and liquefied petroleum gas. Propane and butane produced from natural gas are important raw materials for modern industry.

[0003] The patent publication number is CN212102726U, and the technical solution disclosed in the patent document is as follows: A natural gas drying device includes a base and a console. A coarse filter is provided on the base, an air inlet is provided on the surface of the coarse filter, a drying tower A is provided behind the coarse filter, a drying tower B is provided on the right side of the drying tower A, pipelines are provided between the drying tower A, the drying tower B and the coarse filter, electromagnetic valves are installed on the pipelines, humidity sensors are installed in the drying tower A and the drying tower B, a dust filter is provided in front of the drying tower B, and an exhaust port is provided on the right surface of the dust filter. There are two drying towers, one for drying and one for regeneration, which can continuously dry and dehydrate natural gas and work uninterruptedly, which is beneficial to the development of industrialization.

[0004] The above patent has the following deficiencies: Although the device can dry and dehydrate during use, the coarse filter is easily clogged. In view of this, we propose an anti-clogging natural gas drying filter. Content of the Utility Model

[0013] Preferably, a liquid-gas separator is fixedly connected to the bottom of the air cooler, and a drainage box is fixedly connected to the bottom of the liquid-gas separator.

[0014] Beneficial effects

[0015] Compared with the prior art, the present utility model provides an anti-blocking natural gas drying filter, which has the following beneficial effects:

[0016] First, for this anti-blocking natural gas drying filter, by starting the motor, the output end of the motor drives the rotating rod to rotate, the rotating rod drives the first movable rod to rotate, the first movable rod drives the second movable rod, and the second movable rod drives the cleaning block to reciprocate up and down to clean the filter plate. Cleaning the filter plate can reduce the resistance and pressure inside the filter, avoid pressure damage to the equipment under high operating conditions, which helps to extend the service life of the filter and related equipment and reduce maintenance and replacement costs.

[0017] Second, for this anti-blocking natural gas drying filter, natural gas enters the filter box through the intake pipe, where it can be roughly filtered to remove some impurities, and then enters the first drying tower. The molecular sieve in the first drying tower adsorbs the moisture in the natural gas under low temperature and high pressure. The dried natural gas after adsorption reaches the exhaust port, thus completing the adsorption drying process. When the molecular sieve is saturated with water, it enters the second drying tower through the switching of the valve. The molecular sieve will desorb water at high temperature, and then enters the compressor for natural gas compression. After pressurization, it enters the heat exchanger. When the natural gas is fully heated to about 200 degrees Celsius, it enters the second drying tower to desorb the moisture from the molecular sieve. The natural gas with high content after desorption enters the liquid-gas separator through the air cooler for liquid-gas separation. The moisture is discharged through the drainage tank. The separated natural gas continues to enter the compressor for recycling and regeneration until the molecular sieve in the second drying tower is completely regenerated. The adsorption and regeneration of the first drying tower and the second drying tower are carried out alternately. BRIEF DESCRIPTION OF THE DRAWINGS
