Abstract
An efficient compressed natural gas filtering device used for a natural gas station house comprises an upper cylinder body, a lower cylinder body and a filter element; a partition board is arranged in the inner chamber of the upper cylinder body and divides the upper cylinder body into a gas inlet end and a gas outlet end which are in threaded connection with a gas inlet port and a gas outlet port respectively; a flange opening is formed at the upper end of the lower cylinder body, and a blowdown valve is arranged at the bottom; the filter element comprises a stainless steel tube, a stainless steel filter screen and two concave end covers; round filter holes are uniformly distributed in the tube wall of the stainless steel tube; the stainless steel filter screen wraps the stainless steel tube and is fixed through the upper concave end cover and the lower concave end cover; a fixing bolt hermetically pass through the central holes of the two concave end covers and is connected with a screw hole at the center of the bottom surface of the upper cylinder body so as to fix the filter element on the upper cylinder body; and the upper cylinder body and the lower cylinder body are fixed through bolts. The filtering device has the advantages of simple structure, low cost, good filter effect, and safety and reliability in operation, can ensure that gas supply is stable under the condition of poor gas quality, and is particularly suitable for pressure reducing stations of compressed natural gas.
Description
(1) Technical field [0001] The invention relates to natural gas station equipment, in particular to a high-efficiency filter device for compressed natural gas used in the natural gas station. (2) Background technology [0002] Compressed natural gas filter devices are usually included in natural gas station equipment, and currently commonly used compressed natural gas filter devices mainly include jacketed filters and cartridge filters. In the case of bad gas quality of compressed natural gas, the selection of jacketed filter can not filter fine particles, and can not protect downstream components; while the use of cartridge filter is good for gas with relatively high water content. It is easy to form dry ice inside the filter, causing the filter to clog and also make the downstream components not work properly. The above two situations will cause the natural gas station building to fail to supply gas to the gas pipeline network normally. (3) Contents of the invention ...
