Abstract
The utility model belongs to a component in a gas transmission pipeline system. In order to overcome the technical problem of a gas filter existing in the prior art, the proposal is specially proposed, the utility model consists of a filter screen and a filter casing body with an air inlet opening and an outlet opening and a drainage opening. The filter screen presents a drum shape, is formed by a screen bottom and a cylindrical screen side wall, and is fixed and installed in the bent pipe-shaped casing body. The filter casing body adopts an axial-flow type structure, and forms a circuitous channel with the filter screen. The filter screen can be made into a double-set structure, the larger passing area is suitable for the filtering of gas with large flow rate, a combination part between the filter screen and the casing body can also increase a secondary filter screen and fiber filtering cotton, and the filter precision is greatly improved. The utility model is suitable for the filtering of various gas such as natural gas, gaseous liquefied petroleum gas, the mixed gas of liquefied petroleum gas and air, city gas, and air, etc., and has wide applicability; the filter precision is high, more than 10 micron particle impurities can be filtered, and the efficiency can reach by 98 percent; the utility model also has the advantages of simple structure, convenient operation, and low manufacture cost.
Description
Technical field: the utility model belongs to a kind of parts in the air delivering pipeline system.It is specifically related to a kind of structure of cydariform filter screen pneumatic filter.
Background technology: in gas transmission and distribution system and all gases makings course of conveying; for the operate as normal that guarantees transmission ﹠ distribution equipment and instrument such as instrument such as pressure regulator, flowmeter and protect it not to be damaged; must remove the solid impurity in combustion gas and all gases makings, must the satisfactory pneumatic filter of installation accuracy in pipeline.These a large amount of pneumatic filters that use are the visual plants in the distributing system.Residual size particles thing impurity causes the damage of various parts or works malfunctioning with gas flow is as easy as rolling off a log in various pipeline constructions.At present, the industrial technology fast development, people's material life improves rapidly, and all gases transfer pipeline rolls up, and is therefore also more and more higher to the requirement of the needs of filter and functional reliability.The structure of pneumatic filter is very simple in prior art, has plenty of the filter of serial connection one planar shaped filter screen in pipeline; Modified to it is also arranged, with the circular arc filter that strengthens by area; The filter of face of cylinder type filter screen then appears in the improvement once again that has.Their common advantages are simple in structure, low cost of manufactures, but the problem that exists is: 1. the gas filtration area is less relatively, efficient is low because reasons in structure makes; 2. the solid particle that the gas that passes through carries directly impacts filter screen, makes that filter screen is easily stifled, rapid wear, service life be short; 3. the manufacturing that causes of version, assembling are not tight, can make gas without filtration the bleeder phenomenon be arranged; 4. life cycle weak point and maintenance are inconvenient.
Summary of the invention: the purpose of this utility model is for overcoming the technical problem that pneumatic filter exists in the prior art and raising the efficiency and special this programme---the pneumatic filter of cydariform filter screen that proposes of functional reliability, it has adopted new structure, impurity particle is concentrated on receive dirty pond, not with the filter screen direct collision, increase the reliability of raising the efficiency and working by area.
By as above design, the pneumatic filter of the cydariform filter screen that the utility model proposed includes filter screen and housing, the filter screen that it is characterized in that it is cydariform, constituted by net bottom and cylindrical net sidewall, be fixedly mounted in the filter housings of syphon shape, there are air inlet, gas outlet in the side of filter housings, and dirty pond and sewage draining exit are received in the below, constitutes circuitous gas channel with filter screen.
In this programme, its filter screen is the Portuguese bowline structure, and parallel connection is installed in the filter housings symmetrically.The density of its filter screen is 50～200 orders.Can increase the filter screen of a secondary filter at the installed surface place of filter screen and filter housings.Between filter screen and secondary filter, can place the fibroid filter pulp.
Adopt this programme can embody following superiority: 1. the housing of the pneumatic filter of this cydariform filter screen adopts curvilinear structures, and gas is circuitous the operation in the centre, and generally particle is all fallen and received in the dirty pond, discharges from sewage draining exit through a period of time, is convenient to attended operation; 2. the particle impurity in the gas not with the filter screen direct collision, be difficult for to stop up filter screen, and improve the filter screen life-span; 3. the filter screen of this programme is compared obvious having increased by area with the filter screen in the prior art, has reduced local losses, has improved filter efficiency, can also adopt the filter structures of two covers by actual needs, can strengthen the flow of filtration and raises the efficiency; 4. this filter has filtering accuracy height, simple in structure, low cost of manufacture, is convenient to the advantage of attended operation and long service life.
Description of drawings: Fig. 1 is the structural representation of this programme cydariform filter screen pneumatic filter.
Fig. 2 is the structural representation of two cover filters of this programme.
Fig. 3, Fig. 4, Fig. 5 are the structural representations of the pneumatic filter in the prior art.
The specific embodiment: the pneumatic filter of this cydariform filter screen is the improvement innovation to the pneumatic filter in the prior art.It is made up of receive dirty pond 4 and the sewage draining exit 5 of the air inlet 3 of the gas outlet 2 of cydariform filter screen 1, filter, filter, filter, its cydariform filter screen is to be made of net bottom and cylindrical net sidewall, use the steel wire of stainless steel material, it is fixedly mounted in the filter housings, filter housings adopts end cover structure above filter screen, is convenient to safeguard and change.For adapting to the special requirement of filtering, can increase the filter screen of a secondary filter in the joint portion of filter screen and filter housings again, fibrous filter pulp also can be inserted in the centre, can obviously improve the precision of filtration.For being adapted to the filtration of big flow gas, filter screen can be made the structure of two covers, and parallel connection is installed within the filter housings symmetrically.The axial flow form has been adopted in its filter housings design, have circuitous route, granule foreign is separated with air-flow at the very start, circuitous air-flow has avoided granule foreign directly to clash into filter screen, both improved the life-span of filter screen, also reduced the filter screen phenomenon of blocking, below filter housings, be provided with sewage draining exit, made blowdown operation convenient.
The product of this programme is applicable to natural gas, gaseous liquefied oil gas, liquefied petroleum gas Filtration with multiple makings such as air Mixture, town gas, air. Because its mistake Filter is much bigger by the filter in the Area Ratio prior art, therefore has in work quality Improve significantly. The area of filter screen can reach the 22-30 of pipe diameter in the design Doubly, improved the efficiency value of filter efficiency minimum point in the filter capability index. Under the operating mode service condition, P is little for the resistance Δ, and local crushing is 50～100Pa, filters Grain is that filtering accuracy is greater than 98% more than the 10 μ m. It also has manufacturing cost simple in structure Low characteristics.
