Horizontal filter separator for gas transmission field

Abstract

The invention discloses a horizontal filter separator for a gas transmission field. The horizontal filter separator comprises a cavity, a filter element, a blind plate, an upstream flow guide plate and a downstream flow guide plate, one end of the cavity is sealed by the blind plate, a gas outlet is formed in the other end of the cavity, and the upstream flow guide plate and the downstream flow guide plate are sequentially arranged in the cavity from the blind plate end to the gas outlet end; a cavity between the blind plate and the downstream flow guide plate is a filter cavity, the filter element is arranged in the filter cavity, a gas inlet is formed in the top of the filter cavity, a first filter cavity drain outlet, a second filter cavity drain outlet and a third filter cavity drain outlet are formed in the bottom of the filter cavity, and the first filter cavity drain outlet is located below the upstream flow guide plate, the second filter cavity drain outlet is positioned in themiddle of the bottom surface of the filter cavity, and the third filter cavity drain outlet is positioned in the filter cavity close to the downstream flow guide plate. According to the horizontal filter separator for the gas transmission field, dust from the blind plate to the upstream flow guide plate can be discharged, the influence of dust accumulation on the filter element can be reduced, the filter efficiency of the filter element is improved, and the service life of the filter element is prolonged.

Description

technical field [0001] The invention relates to the field of oil and gas storage and transportation filtration, in particular to a horizontal filter separator for a gas transmission field. Background technique [0002] After the natural gas is extracted, it contains a large amount of dust and other impurities, which enter the lower-level process, affecting normal production and safety. After the natural gas is extracted, it needs to be filtered and separated before it can be transported downstream. [0003] Such as figure 1 As shown, the horizontal filter separator currently used in the gas transmission field includes a cavity, a filter element 14, a blind plate 11, an upstream deflector 12, and a downstream deflector 13. One end of the cavity is sealed by a blind plate 11, and the blind plate 11 It is detachably connected with the cavity, and the other end of the cavity is provided with a gas outlet 22, and the upstream deflector 12 and the downstream deflector 13 are arra...

AI Technical Summary

Problems solved by technology

The sewage outlet 31 of the filter chamber of the existing horizontal filter separator is far away from the blind plate 11, and is arranged in the middle of the filter chamber 1 or near the downstream deflector 13, and the dust mostly gathers at the blind plate 11 to the upstream deflector 12, relatively Since the sewage outlet 31 of the filter chamber is located far away, only a small amount of dust in the filter chamber 1 can be discharged from the sewage outlet 31 of the filter chamber during sewage discharge, and the remaining dust will accumulate between the blind plate 11 and the upstream guide plate 12, resulting in horizontal filtration. The pressure difference of the separator increases, thereby shortening the service life of the filter element 14, affecting the gas quality of the downstream natural gas, and even causing the blockage of the filter chamber 1 in severe cases
