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
The present invention relates to natural gas station equipment, particularly a kind of compressed natural gas high efficiency filter device that is used for the natural gas station.
(2) background technology
In natural gas station equipment, generally include the compressed natural gas filter, compressed natural gas filter at present commonly used mainly comprises two kinds of jacket type filter and cartridge filters.Under the bad situation of compressed natural gas makings, select for use the jacket type filter not have filtration for fine particle, the downstream parts are not had protective effect; And the employing cartridge filter then forms dry ice in filter interior to water content than higher makings easily, causes plugged filter, also can make the downstream parts can't operate as normal.Below either way will cause the natural gas station can't be normally to the gas ductwork air feed.
(3) summary of the invention
The objective of the invention is to above-mentioned existing problems; A kind of compressed natural gas high efficiency filter device that is used for the natural gas station is provided; This apparatus structure is simple, cost is low, good filtration effect, safe and reliable to operation; Can under the situation of multiple bad makings, remedy each other, it is single to have removed filter from, the situation of job insecurity.
Technical scheme of the present invention:
A kind of compressed natural gas high efficiency filter device that is used for the natural gas station; By upper shell; Lower shell and filter core constitute; The upper shell profile is cylinder, and inner chamber is provided with dividing plate and upper shell is divided into inlet end is connected with the interface thread of giving vent to anger with the outlet side and with intake interface, and upper shell bottom center is provided with screw; Lower shell is the cylinder type of bottom bulkhead, and the lower shell upper end is a flange port, and bottom centre is provided with sewage draining exit and blowoff valve; Filter core is a cylinder type; Filter core comprises stainless steel tube, stainless steel filtering net and upper and lower two matrix end caps; The stainless steel tube tube wall is evenly equipped with circular filter opening; Stainless steel filtering net is wrapped in the stainless steel tube outside and fixes through upper and lower two matrix end caps, and two matrix end caps are respectively equipped with centre bore, and last matrix end cap central bore periphery is provided with passage; The centre bore of two matrix end caps of set bolt hermetically passing also is connected with the screw of upper shell bottom center filter core is fixed on the upper shell; This moment, the stainless steel tube of filter core suitable for readingly communicated with the outlet side of upper shell, and filter core partly communicates with the inlet end of upper shell with annular space between the lower shell, and upper shell and lower shell pass through bolt.
Said stainless steel tube specification is Φ 32X3, and length is 200mm; The circular filter opening diameter of tube wall is Φ 5, and pitch of holes is 15mm.
Said stainless steel filtering net specification is 270 orders, and thickness is 50 μ m, and the number of plies is 2 layers.
The scope of application of the present invention is: door station, industrial park and the residential quarter station in large-scale gas company, city.
Advantage of the present invention is: this apparatus structure is simple, cost is low; Good filtration effect, safe and reliable to operation; Can under the situation of multiple bad makings, remedy each other, it is single to have removed filter from, and the situation of job insecurity is specially adapted to the compressed natural gas pressure-reducing station and uses.
