Embodiment Construction

[0026] The low-pressure natural gas / coal bed gas purification device of the present invention will be further described in detail with specific embodiments below in conjunction with the accompanying drawings. It should be understood that the following examples are only used to illustrate the present invention but not to limit the scope of the present invention.

[0027] like figure 1 As shown, the low-pressure natural gas / coal bed methane purification device of the present invention includes a tank body 10 in which a gravity settling chamber 20 , a cyclone separator 30 and a gas filter 40 are sequentially arranged.

[0028] Wherein, the gas filter 40 includes two layers of filter boxes, which are respectively the filter box 1 41 of the upper layer and the filter box 2 42 of the lower floor, and the filter box 1 41 and the filter box 2 42 are filled with hollow Fibers, preferably hollow fibers with 7 to 13 holes. Those skilled in the art can easily understand that although th...

Abstract

The invention discloses a low-pressure natural gas / coal-bed gas purifying device. The low-pressure natural gas / coal-bed gas purifying device comprises a tank body, wherein a gravity sedimentation chamber, a cyclone separator and a gas filter are sequentially arranged in the tank body. By adopting the three-level processing way of the gravity sedimentation, cyclone separation and filtering, different solid-liquid impurities contained in the low-pressure natural gas or coal-bed gas can be high-efficiently eliminated, and the removable quantity of the liquid and solid impurities in the gas which is subjected to the third-level processing can reach 1000 g / 10<4>m<3>(gas) or more.

Description

technical field [0001] The invention relates to gas filtering equipment, in particular to a low-pressure natural gas / coal bed gas purification device. Background technique [0002] With the application of various development methods in oilfields, the gas quality of natural gas raw materials before initial processing is getting worse and worse, containing a large amount of oil, water and fine dust impurities. The existence of these impurities will cause blockage or even damage to precision pressure regulating equipment and metering equipment, affecting production and causing losses. At the same time, since solid phase particles are the natural nuclei of water freezing and natural gas hydrate formation under low temperature conditions, their existence exacerbates the problems existing in the production of water-containing impurity gas. [0003] In order to eliminate the great harm caused by water and dust in the gas, gravity sedimentation separation, centrifugal separation an...
