Abstract
The utility model discloses a grade-type gas filter which is composed of an inlet flange, an outlet flange and a filtering chamber. One end of the filtering chamber is provided with the inlet flange, and the other end is provided with the outlet flange; the inside of the filtering chamber is provided with a primary filter screen, an intermediate filter screen and a fine filter screen in sequence from the inlet flange to the outlet flange. A sediment chamber is arranged between the primary filter screen and the inlet flange; a gravity collision plate is arranged in the sediment chamber; a rectangle hole is arranged on the gravity collision plate; the bottom of the sediment chamber is provided with a sewage draining valve. The air inlet end of the filtering chamber is provided with an inlet pressure gauge, and the air outlet end is provided with an outlet pressure gauge. The grade-type gas filter adopts a grade and fast-assembly structure, thereby being convenient for the maintenance and the cleaning, having the on-line sewage draining function, little voltage drop, good circulating property and high purifying efficiency. Compared with the prior art, the grade-type gas filter has the advantages of grade filtering, simple structure, practicality, easy manufacture, low cost, etc.
Description
Technical field
The utility model relates to a kind of filter, especially a kind of fine filter that is used for gases such as natural gas.
Background technology
In natural gas, associated gas and the air Compressed Gas, contain some moisture, SO
2, impurity such as dust and little oil droplet, must be through purified treatment.Filter be the most basic also be a large amount of primary purifying equipment that use, traditional single-stage sieve plate or the screen net structure of the most of use of at present common pneumatic filter, there are poor filtration effect, manufacturing cost height, efficient is low and safeguards inconvenient problem, especially can not filter the impurity of different-grain diameter simultaneously.
The utility model content
The technical problems to be solved in the utility model is for overcoming above-mentioned deficiency, and a kind of stagewise pneumatic filter simple in structure, easy to use is provided.
The utility model is taked following technical measures: a kind of stagewise pneumatic filter, form by suction flange, outlet(discharge) flange, filter chamber, filter chamber's one end is equipped with suction flange, the other end is equipped with outlet(discharge) flange, and elementary filter screen, intermediate filter screen, meticulous filter screen are installed from the suction flange to the outlet(discharge) flange in the filter chamber successively.
Be provided with expansion chamber between elementary filter screen and suction flange, the gravity impingement plate is installed in the expansion chamber, the gravity impingement plate is provided with the rectangle hole.The expansion chamber bottom is provided with blowoff valve.
Filter chamber's inlet end is equipped with inlet pressure gauge, in the outlet side delivery gauge is installed.
The beneficial effects of the utility model are: adopt classification ready-package structure, be convenient to maintenance clean, have online dirt eliminating function, pressure drop is little, and circulation is good, the purification efficiency height, and manometric the setting realized the pressure reduction monitoring function, can in time clean filter screen in view of the above.Can improve processing safety, reduce operator's labour intensity, solve the problem of filtering different-grain diameter impurity simultaneously effectively.Compared with prior art, have classified filtering, simple in structure, practical and easily processing and manufacturing and advantage such as with low cost.

The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in the figure, a kind of stagewise pneumatic filter, form by suction flange 9, outlet(discharge) flange 12, filter chamber 13, filter chamber's 13 1 ends are equipped with suction flange 9, the other end is equipped with outlet(discharge) flange 12,12 elementary filter screen 5, intermediate filter screen 6, meticulous filter screen 7 is installed successively from suction flange 9 to outlet(discharge) flange in the filter chamber 13.
Be provided with expansion chamber 3 between filter chamber's 13 inherent elementary filter screens 5 and the suction flange 9, gravity impingement plate 2 is installed in the expansion chamber 3, gravity impingement plate 2 is provided with rectangle hole 1.Expansion chamber 3 bottoms are provided with blowoff valve 4.
Filter chamber's 13 inlet ends are equipped with inlet pressure gauge 10, and delivery gauge 11 is installed in the outlet side.
13 sides, filter chamber are equipped with filters chamber cap 8, links together by fixed screw and filter chamber.
The stainless steel cloth 14 of different meshes is installed respectively on elementary filter screen 5, intermediate filter screen 6, the meticulous filter screen 7, is respectively applied for and filters carse, medium and small impurity.
During use, after medium enters filter chamber 13 from suction flange 9, heavier particle and moisture content under gravity impingement plate 2 effect at first in expansion chamber 3 sedimentations, can regularly get rid of by blowoff valve 4, then respectively by elementary filter screen 5, intermediate filter screen 6 and meticulous filter screen 7, the carse, medium and small impurity of filtering, last cleaning medium is gone out from outlet(discharge) flange 12.When the filter filter screen adheres to accumulated impurity more for a long time, inlet pressure gauge 10, delivery gauge 11 are measured differences and will be increased, can be according to the timely cleaning and filtering net of actual conditions needs.
The utility model is mainly used in the fine filtering of gas mediums such as petroleum gas or air, also can be used for the fine filtering of other non-aggressive low viscosity fluid medium.
