A gas drying filter

Abstract

The invention discloses a fuel gas dry filter. The fuel gas dry filter is composed of a filter body, a filter element, a filter cover, a water releasing valve and a differential pressure gauge. The fuel gas dry filter is characterized in that the filter body is of an integrated structure, and comprises an inlet cavity, a filter element seat, a communicating cavity, ice collecting sheets, ice accommodating cavities, a water collecting groove and an outlet cavity, wherein the inlet cavity is formed in the lower end of the filter body; the filter element seat is arranged above the inlet cavity; the filter cover is assembled to the upper end part of the filter body by a screw; the side wall of the filter body is provided with the outlet cavity; the inner side wall of the filter body is provided with the ice collecting sheets; the adjacent ice collecting sheets surround define the ice accommodating cavity; the bottom parts of the ice accommodating cavities are provided with the water collecting groove in a communicating manner, the water releasing valve is assembled on the water collecting groove; a connecting pipe on which the differential pressure gauge is assembled is arranged between the inlet cavity and the outlet cavity; the filter element is a stainless steel cylinder, and is coated with fiber filter materials; the ice collecting sheets are uniformly distributed around the filter element in the circumferential direction. The fuel gas dry filter provided by the invention can effectively eliminate the possibility of pipeline blocking and failure of a pressure regulator, caused by icing of moisture in fuel gas.

Description

technical field [0001] The invention belongs to the technical field of gas transmission and distribution, and in particular relates to a gas drying filter. Background technique [0002] In the process of gas pressure regulation and distribution, when the moisture content in the gas is high, on the one hand, the calorific value of the gas will be reduced, and on the other hand, the phenomenon of "ice blockage" will appear in winter, that is, it is installed on the inner wall of the open-air pipeline or outdoors. Inside the pressure regulator, the water in the gas is precipitated in the form of freezing, which will affect the normal operation of the pressure regulator and even block the transmission and distribution pipeline, causing interruption of gas supply to downstream users and even causing safety accidents. For this reason, before the gas enters the small-diameter pipeline or enters the pressure regulator, it is necessary to perform an effective drying treatment on the ...

Problems solved by technology

However, if special drying equipment is used to dry the gas, on the one hand, investment in the drying equipment is required, and special management of the operation of the drying equipment is required, so the cost of gas transmission and distribution will be high, and it is only suitable for large-scale gas Gas drying treatment of transmission and distribution equipment
