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 house equipment, particularly a kind of compressed natural gas effective filter for natural-gas station house.
(2) background technology
In natural-gas station house equipment, generally include compressed natural gas filter, at present conventional compressed natural gas filter mainly comprises two kinds of jacketed type filter and cartridge filters.In the situation that compressed natural gas makings is bad, select jacketed type filter not have filtration for fine particle, downstream parts are not had to protective effect; And employing cartridge filter easily forms dry ice in filter interior to the higher makings of water content, cause plugged filter, also can make downstream parts normally work.Below either way will cause the natural-gas station house cannot be normally to gas ductwork air feed.
(3) summary of the invention
The object of the invention is for above-mentioned existing problems, a kind of compressed natural gas effective filter for natural-gas station house is provided, this apparatus structure is simple, cost is low, good filtration effect, safe and reliable to operation, can the in the situation that of multiple bad makings, mutually make up, removed filter from single, the situation of job insecurity.
Technical scheme of the present invention:
A kind of compressed natural gas effective filter for natural-gas station house, by upper shell, lower shell and filter core form, upper shell profile is cylinder, inner chamber is provided with dividing plate and upper shell is divided into inlet end and outlet side and is connected with intake interface and the interface thread of giving vent to anger, and upper shell bottom center is provided with screw, lower shell is the cylinder type of bottom bulkhead, and lower shell upper end is flange port, and bottom centre is provided with sewage draining exit and blowoff valve, filter core is cylinder type, filter core comprises stainless steel tube, stainless steel filtering net and upper, lower two matrix end caps, stainless steel tube tube wall is evenly equipped with circular filter opening, stainless steel filtering net is wrapped in stainless steel tube outside and passes through upper, lower two matrix end caps are fixed, two matrix end caps are respectively equipped with centre bore, upper matrix end cap central bore is arranged with passage outward, the centre bore of two matrix end caps of set bolt hermetically passing is also connected filter core is fixed on upper shell with the screw of upper shell bottom center, now the stainless steel tube of filter core is suitable for reading communicates with the outlet side of upper shell, annular space part between filter core and lower shell communicates with the inlet end of upper shell, upper shell and lower shell are bolted.
Described 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.
Described 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: large-scale gas company, door station, industrial park and the residential quarter station in city.
Advantage of the present invention is: this apparatus structure is simple, cost is low; Good filtration effect, safe and reliable to operation; Can the in the situation that of multiple bad makings, mutually make up, remove filter from single, the situation of job insecurity, is specially adapted to compressed natural gas and uses.
