Abstract

The utility model provides a metal fiber felt type dust removing device and is composed of a tank body, a gas inlet port, a gas outlet port, a dust outlet port and a filtering net. The filtering net is a stainless steel fiber felt net to be folded into multiple folding angles to be fixed in the tank body and form a certain of dip angle with the horizontal direction of the tank body. Multiple levels of filtering nets can be arranged according to the need, and the hole diameter of the hole of every filtering net diminishes gradually. The hole diameter of the hole of every filtering net is 0.3-60 muon m, and the consistency of the holes is 1.1*10< 9 >-2.7*10< 4 >. The upper parts of the filtering nets are provided with a vibrating device, and the dust outlet port is provided with a dust collecting tank. The metal fiber felt type dust removing device has the advantages of high dust removing effect, low cost and simplicity.

Description

Metal fiber felt formula deduster

The utility model relates to a kind of metal fiber felt formula deduster, belongs to environmental protection dedusting technology field.

At present, all need cleaner in fields such as generating, metallurgy, heating power, petrochemical industry, with the pollution abatement environment purification.Existing deduster has modes such as electric precipitation, bag-type dust, water film dedusting and cyclone dust removal.The dust collection efficiency height is adopted in a large number, but the cost height, floor space is big, operation expense is high.Though bag-type dust is simple in structure, be subjected to the restriction in cloth bag life-span, easy to wear, heatproof is low, so maintenance cost is also high, and the high temperature occasion is inapplicable.Water film dedusting efficient is on the low side, and cyclone dust removal equipment is easily breakdown.

The utility model and purpose are to be filtrate with resistant to elevated temperatures stainless steel fibre felt, design a kind of simple in structure, the efficient height, take up an area of little, the deduster that cost is low.

The technical solution of the utility model is this metal fiber felt formula deduster, comprise casing 1, air inlet 2, gas outlet 3, ash hole 4 and filter screen 5, filter screen 5 is met airintake direction and is fixed in the casing 1, it is characterized in that filter screen 5 is folding formula stainless steel fibre feltworks, promptly feltwork vertically has 1-N knuckle α ₁, α ₁Between 60 °～180 °.

Above-mentioned metal fiber felt formula deduster, the mesh aperture of the feltwork layer of filter screen (5) is 0.3～60 μ m, feltwork is attached on the stainless steel supporting layer, filter screen (5) can be established 1～4 grade, when multistage, the filter screen mesh aperture diminishes as required step by step, and when establishing one-level, mesh is 10～20 μ m, when establishing two-stage, first order filter screen mesh aperture is 20～40 μ m, and second level filter screen mesh aperture is 2～10 μ m, when establishing level Four, the aperture of first order filter screen (5-1) is 40～60 μ m, the aperture of the second level (5-2) is 10～20 μ m, and the aperture of the third level (5-3) is 2～8 μ m, and the fourth stage is 0.3～1 μ m.

Above-mentioned metal fiber felt formula deduster is characterized in that there is reinforcement 6 at the folding place of filter screen 5.

Above-mentioned metal fiber felt formula deduster is characterized in that filter screen 5 is from the horizontal by α ₂The angle, α ₂The angle is 30 °～90 °.

The utility model has the advantages that:

1, filtering layer is the folding formula, filtering net surface and the charge air flow direction α that has angle ₁, make air-flow act on wire side except making the power that flue gas sends, also have a side-blown power along the filtering layer face, this power can help to blow off attached to the laying dust on the filter screen, has the automatic ash removing effect.

2, folding formula structure itself just has the effect that improves intensity, also can add reinforcing bar at the folding place and support, and reinforces filter screen, the requirement of filtering layer intensity when having guaranteed than large tracts of land.

3, folding formula structure is when high velocity air passes through, and flue dust forms little backflow near filtering layer, and the backflow flue dust can reflex to adjacent folding face changed course to be passed through, and is equivalent to increase the backflow area.

4, filter screen and horizontal direction angle α ₂Be 30 °～90 °, its angle parameter is determined that by overall design parameters this angle also helps deashing.

5, this filter screen is a metal, and not only mar proof, corrosion-resistant of stainless steel supporting layer is particularly arranged, and the intensity height, but easily the taking off property that folding endurance and dust are arranged is fixed with metal cabinet simultaneously, has reached the purpose of reliable ground, do not produce static and spark, particularly suitable to filtering inflammable and explosive dust.

6, can be designed to multicell as required, promptly multistage filter screen, and can adjust the parameter of the penetrating mesh aperture of multistage filter screen, and not only can select the sum of series aperture of filter screen as required, and reach the flue dust classification, be convenient to utilization to useless dirt, being beneficial to turns waste into wealth.In addition, this deduster has simply, efficient, low-cost, advantages such as the life-span is grown, few maintenance.

Below accompanying drawing is described: Fig. 1 is that top cross-sectional view, Fig. 3 that the utility model filter structure schematic diagram, a Fig. 2 are Fig. 1 is that filtering layer becomes α with level ₂Structural representation, Fig. 4 are multistage filter screen embodiment schematic diagrames during angle.1 is casing, the 2nd among the figure, air inlet, the 3rd, and gas outlet, the 4th, ash hole, the 5th, filter screen, 5-1～5-4 are filter screen, α ₁Represent filter screen knuckle, α ₂Represent filter screen and horizontal direction angle, the 6th, reinforcement, the 7th is represented vibrating mechanism.

Embodiment of the present utility model: accompanying drawing has provided the technical scheme of implementing, and other parts all are ordinary constructions among the figure, mainly are that filter mesh layer 5 is selected special stainless steel metal feltwork for use, and aperture is 0.3～60 μ m on it, and the density in hole is 1.1 * 10 ⁹～2.7 * 10 ⁴, feltwork thickness is 0.5～1.0mm, is actually the layer of metal fabric nonwoven cloth attached on the stainless steel supporting layer.But requirement has low windage folding endurance and certain toughness and intensity, according to design α such as the flow of application scenario flue dust, humidity, composition, viscosity, abrasiveness, corrosivity ₁, α ₂The choosing value at angle.When the filtering layer area is big, should add the stainless steel reinforcement at the knuckle place, reinforcement can be the angle bar shape, also can be cylinder, square tube shape etc.Can add vibrating mechanism at the filter screen upside, take vibration cleaning.When cigarette ash when air inlet is blown into certain speed, be filtered off greater than the dust of filter screen mesh aperture, below ash hole, be provided with disposal box, dust falls into disposal box through vibration.When needed, through multistage filter screen, can filter step by step, and the dust of various diameters is utilized respectively.
