Description
Technical field
The utility model relates to a kind of strainer, specifically refers to a kind of natural gas filter.
Background technology
A kind of natural gas filter of normal use in the transmission & distribution of city gas.Enter the Sweet natural gas of gas distribution station, because carry at a distance or other reason, always with a small amount of micron order or submicron order impurity, (Sweet natural gas produces erosion to pipeline inwall, upper level gas gathering station, purification plant or gas distribution station carry out the residual impurity after separation, dedusting, purification to Sweet natural gas) the normal smooth running of impact station internal pressure-regulating device, measuring apparatus, so all must come gas to carry out purifying and dedusting to upper level at last one station to user's air feed, to guarantee tight gas supply.
At present, existing strainer is the filter cylinder that Sweet natural gas first directly enters strainer, after filter cylinder purifies, then from the space outflow filter between filter cylinder and filter body.Impurity is done inertial motion with the flow at high speed of gas, directly impacts filter cylinder, and over against the silk screen at gas feed position, this place's silk screen, owing to being directly subject to washing away of air-flow and impurity, is damaged at first.The silk screen of filter cylinder is no matter which partly damages, all will make strainer reduce, even lose the function of filtration, dedusting, purification, Sweet natural gas dedusting function is concentrated on to filter cylinder on the silk screen at Imported gas position. and impurity exists in cartridge filter all the time, cause filtration area to reduce, gas can be done turbulent motion in filter cylinder, make the small dust sink-float can not sedimentation in filter cylinder, reduced filter effect and the life cycle of strainer, increased maintenance workload.
Utility model content
The utility model provides a kind of natural gas filter, easily damaged over against the filter cylinder at inlet mouth place and the problem that causes filter cleaning function to reduce reaches the object that improves strainer job stability while solving natural gas filtering.
The purpose of this utility model reaches by the following technical programs:
The utility model comprises housing and gland, housing is connected by flange with gland, described housing is provided with inlet mouth and air outlet, housing bottom is provided with sewage draining exit, the inside of housing is provided with filter cylinder, described filter cylinder is communicated with air outlet, and inlet mouth is communicated with enclosure interior, also comprises the separation net being arranged between inlet mouth and filter cylinder.The top of housing is connected and fixed by welding and outside erecting frame, and case top is connected by flange with gland, and when filter cylinder need to be safeguarded, quick release is installed, and simplifies the operation; The bottom of housing is provided with sewage draining exit, can not only play the effect of emptying pressure release, the solid particulate isolating or liquid impurity can also be got rid of to the convenient clean and maintenance to filter cylinder in filter cylinder; The dust of the larger particles in the Sweet natural gas being passed through by inlet mouth or impurity are done inertial motion with Sweet natural gas flow at high speed, and when air-flow runs into obstacle and detours, dust is online because inertia departs from air flow line and bumps against the filter wire of strainer, and barred is in net; After the filtration of one-time surface formula, Sweet natural gas continues by a plurality of filter pore on bed filtration silk screen, filter pore has many bending channels, the number of plies is more, be that filtration area is larger, the dust in Sweet natural gas constantly bumps with filtering silk screen, and very little granule dust is also done random pedesis, the kinetic energy of dust constantly reduces, and is stuck in filters in silk screen until can not move; Finally by the Sweet natural gas filtering, passing through air outlet discharge filter;
The separation net being provided with between inlet mouth and filter cylinder, make the not direct impact core cylinder silk screen of high velocity air that contains impurity, with separation net, remove the impurity of larger particles, these particles also easily come off at housing bottom, also can change air flow line in addition, make Sweet natural gas reach more uniformly the deep layer of filtering silk screen, and separation net is detachable, can remove quickly or install; Compare with existing strainer, the outer bottom below of filter cylinder of the present utility model is steel plate, filtering air inlet direction and air outlet direction are point-blank, the direction of the inlet mouth of strainer and air outlet is exchanged, the impurity that can allow dedusting get off sticks to filter cylinder outside or is deposited on the steel plate of housing bottom, the dust containing capacity of strainer is increased, and can regularly by sewage draining exit, discharge, make its running stable.
Further, described filter cylinder top is provided with scarp, and scarp and horizontal plane are at 45 °, and described inlet mouth is over against scarp, and filter cylinder is communicated with enclosure interior by scarp.Filter cylinder adopts the design of upper end open, lower end closure, bottom at housing is provided with scarp, scarp is over against inlet mouth, Sweet natural gas directly enters filter cylinder from inlet mouth, filtration silk screen by multilayer carries out filtration treatment, thereby increased the contact area of Sweet natural gas and filter cylinder, be convenient to Sweet natural gas and enter into fast filter cylinder and filter.
Further, the bottom of described housing is semisphere, and described sewage outfalls setting is in the lower-most point of the bottom of described housing.Usually housing bottom is made as plane, easily causes the impurity filtering to be piled up in convenient placement, is difficult to get rid of from sewage draining exit; The housing bottom of semisphere design can make impurity from sewage draining exit, flow out fast under the effect of self gravitation, the cleaning of convenient filter.
Further, also comprise one deck trevira being arranged on filter cylinder.For avoiding or alleviate the wash number of filter element, can add in appearance one deck trevira at filter cylinder, and periodic replacement.
Further, also comprise the differential pressure gauge that is arranged on surface of shell, the two ends of described differential pressure gauge are connected with inlet mouth, air outlet respectively.Usually, strainer can regularly clean, but because uncertainty causes filter core net damaged, does not carry out in time dress watch and can cause the filter effect of Sweet natural gas greatly to reduce; Differential pressure gauge can be pointed out the change value of pressure of strainer rear and front end in real time, for the strainer suitable clean period of statistics provides scientific basis, plays cost-saving, the time, and the effect maintaining easily, can save energy and reduce the cost effectively.
The utility model compared with prior art, there is following advantage and beneficial effect:
