Gas filter capable of reducing pressure loss and prolonging service life of filter element

Abstract

The invention discloses a gas filter capable of reducing pressure losses and prolonging the service life of a filter element, and aims to solve the problem that a turbulent flow phenomenon can be easily caused in a filter element of a conventional gas filter and thus large pressure losses are caused in a filtering process and the filter element is frequently replaced. A 90 degree arch-shaped benttube (7) is connected with an upper gas inlet of a filter element (5), the other end of the 90 degree arc-shaped bent tube (7) is connected with the large end of a horn opening (6), a lower sealing cover tray (4) is arranged at the lower end of a filter element (5), a conical central convex (9) is arranged in the center of the lower sealing cover tray (4), annular water discharge through holes (10) are formed in the tray of the lower sealing cover tray (4) on the outer side of the conical central convex (9); a water storage tray (11) is arranged below the annular water discharge through holes(10); an air flow allocation arc-shaped partition plate (8) is arranged in the 90 degree arc-shaped bent tube (7). The gas filter is small in pressure loss, and the overall operation performance and the gas making quality level of the equipment can be improved.

Description

technical field [0001] The invention relates to a purification device for producing nitrogen, oxygen and biogas, in particular to a gas filter in the purification device. Background technique [0002] In nitrogen, oxygen and biogas purification devices, the gas filter is a special device for filtering the source gas. Its function is to filter out impurities such as water, oil, and dust in the source gas to improve the efficiency of the gas Cleanliness; the gas filtration system is an important prerequisite for the preparation of various gases. If the source gas fails to meet the design requirements after passing through the filtration system, the gas containing moisture and impurities will enter the subsequent host, which will pollute the core components of the subsequent host. Therefore , The gas filter is very important to the whole purification device. The gas filter in the prior art is to filter the gas source gas by setting a multi-stage filter. The existing multi-stag...
