Description

Natural gas pipeline filter Technical Field The utility model relates to the field of natural gas pipe connection, in particular to a natural gas pipe filter. Background During the process of natural gas exploitation, transportation and utilization, a natural gas pipeline filter plays a vital role and is used for removing impurities and moisture in natural gas so as to ensure the quality of the natural gas and the safety of a system. Conventional natural gas pipeline filters generally employ a single screen structure, and although some impurities can be removed to some extent, the filtering effect is limited, and especially the removing effect for tiny particles and liquid water vapor is not ideal. In addition, the filter screen replacement and cleaning operations of the conventional filter are relatively complicated, and the residence time of the filtered matters in the filtering area is long, so that the filtering efficiency is easily influenced, and even secondary pollution is possibly caused. In order to improve the natural gas filtering effect, reduce the exposure time of the filtered matters in the filtering area, simplify the filter screen replacement and cleaning process, and a novel natural gas pipeline filter is urgently needed in the market. Disclosure of utility model The utility model aims to provide a natural gas pipeline filter, which solves the problems of filtering and impurity removal of the natural gas. The utility model is realized by the following technical scheme: The utility model provides a natural gas pipeline filter, includes the filter box, the filter box is divided into the gas filtering area of upper strata and the filtration collecting area of lower floor through horizontal division board, be provided with a set of filter screen frame that relative was placed the piece and a set of filter screen frame is placed the piece and is movably arranged between the piece and has had the filter screen to filter screen frame, filter screen frame is placed the piece and has set up the filtration temporary collecting tank of parallel filter screen frame and filter screen frame on the horizontal division board of filter screen frame below, and the filtration temporary collecting tank one-to-one is placed the piece with every filter screen frame and is placed the piece and correspond, filtration temporary collecting tank still communicates with the filtration collecting area, set up natural gas inlet tube and natural gas outlet tube respectively in two sides of the solid piece of placing of filter box parallel filter screen frame.
