Natural gas impurity removal equipment with cooling function and method thereof

Abstract

The invention discloses natural gas impurity removal equipment with a cooling function and a method thereof, wherein the natural gas impurity removal equipment comprises an impurity removal box and a gas inlet guide pipe, the gas inlet guide pipe is arranged in the middle of the upper end of the impurity removal box and used for conveying natural gas; the right upper side of the impurity removal box is provided with a gas exhaust guide pipe used for conveying treated natural gas away, and the lower end of the gas inlet guide pipe is rotationally provided with a rotating cylinder; a power blade is erected on the inner wall of the rotating cylinder, a plurality of compression and fragmentation mechanisms used for compressing and discharging gas to improve the heat exchange effect are distributed on the outer side of the rotating cylinder in an array mode, and a washing pool used for submerging the compression and fragmentation mechanisms is arranged in the impurity removal box. The equipment is designed for disadvantages of an existing device, the natural gas can be cooled, the natural gas can be also washed, double treatment of washing and cooling is met, and the practicability is high.

Description

technical field [0001] The invention relates to the technical field of natural gas, in particular to a natural gas impurity removal device and method with a cooling function. Background technique [0002] Natural gas needs to be transported under pressure during the transmission process, which will undoubtedly cause the temperature of natural gas to rise, so it is necessary to cool down the natural gas in advance. However, there are also some impurities in natural gas. The sources of impurities in natural gas can be divided into two types, one is The remaining impurities after natural gas mining and processing, and the other is new impurities generated during later storage or transportation. The existing natural gas is transported to the user station through pipelines. The natural gas itself contains certain impurities, and the natural gas is carried during the transportation process. Impurities in the pipeline, during pipeline transportation, tiny natural gas impurities wil...

Problems solved by technology

[0002] Natural gas needs to be transported under pressure during the transmission process, which will undoubtedly cause the temperature of natural gas to rise, so it is necessary to cool down the natural gas in advance. However, there are also some impurities in natural gas. The sources of impurities in natural gas can be divided into two types, one is The remaining impurities after natural gas extraction and processing, and the other is new impurities generated during later storage or transportation. The existing natural gas is transported to the user station through pipelines. The natural gas itself contains certain impurities, and the natural gas is carried during the transportation process. Impurities in the pipeline, during pipeline transportation, tiny natural gas impurities will gradually accumulate, and will be passively heated in the boosting of natural gas, and a very small part of natural gas such as methane and ethane will be cracked under high temperature, and will be released under certain conditions. It is down-converted into a solid polymer and becomes a solid impurity in natural gas. After being connected to the pipeline at the user end, it is easy to transport the carried impurities into the pipeline at the user end. For the above-mentioned requirements of impurity removal and cooling, the existing patent announcement number is CN213388539U The patent only provides impurity removal, but the existing patent notification number is CN212225481U patent provides cooling of natural gas, it is obvious that these two independent methods cannot meet the existing needs
