Abstract

The utility model discloses a wet vibrating string dust removed device for purifying dusty gas and harmful gas on the spot for a well of a coal mine, a coal separating plant, an industrial boiler and a coal-fired boiler. The device is composed of a water supply pipe, a gas inlet, a foggy sprinkler head, separating dehydrator, a purified gas outlet, a sewage discharging hole, a metal casing and a vibrating string filter plate which is in fence curtain shape. The vibrating string filter plate is formed by small-diameter fibres winding on a frame and arranging in parallel in the same direction. The vibrating string filter plate is placed on a charging sidewind channel and can shield all cross sections. The vibrating string filter plate has strong self-cleaning capacity without cleaning frequently. Consequently, dust removed efficiency is in direct proportion with the speed of filtered-wind filtered by the vibrating string filter plate. The utility model has the advantages of small size, light weight and simple structure.

Description

Wet vibrating string dust removed device

The utility model relates to the ventilating dust-arrester that a kind of dusty gas purifies on the spot.Be applicable to driving face in coal mine and stope, and the dust laden air in the place of product dirt operation such as disintegrating machine, coal bunker mouth, transfer point, coal preparation plant purifies on the spot; Also can be used for smoke elimination, the dedusting of Industrial Boiler, coal-burning boiler, can eliminate the part poisonous and harmful composition in the gas simultaneously.

The wet type dust trapping device of existing colliery or boiler, its dust-catch structure mainly is the moistening filter course (bed) of netting of single or multiple lift longitude and latitude or the laminated formation of filtrate fiber, representatively catches dirt for water-bath type; This device mainly is to utilize the abundant collision between water curtain and the dust that dust is combined with water, and its feature is that working resistance is big, generally more than 700 handkerchiefs, have up to 3700 handkerchiefs, power consumption is high, it is few to handle air quantity, efficiency of dust collection is low; (200mg/m when the processing dust concentration is high ³) easily stop up, need frequent disassembly, cleaning, to the dust removing rate low (below 80%) of respirable dust (less than 10 μ m), and volume is big, heavy, filtration velocity low (efficiency of seizing dust and wind speed are inversely proportional to).

It is a kind of simple in structure that the purpose of this utility model is to provide, the efficiency of seizing dust height, and self-purification capacity is strong, does not need the special wet type vibratory string dust trapping device that cleans.

The utility model is made up of supply channel, gas feed, waterfog head, separating and dehydrating mouth, purified gas outlet, sewage draining exit, metal shell, it is characterized in that on air inlet sidewind passage, placing a vibratory string filter, make it can shelter from whole sections of gas channel, this vibratory string filter is to be wrapped in by small diameter fiber cocurrent and parallel to be arranged be the palisade curtain, can regulate arbitrarily with layer fiber and interlayer fibre gap.

Description of drawings

Below in conjunction with accompanying drawing the utility model is further described:

Shell of the present utility model (8) adopts steel plate to be welded, and dusty gas enters by gas feed (2) passage, through the water outlet of supply channel (1) control waterfog head (3).Placement vibratory string filter (4) shelters from full section and catches dirt on gas channel.When waterfog head (3) is sprayed on vibratory string filter (4), the moisture film that forms can make the weightening finish of dust wet side, coalescence becomes to remain in a standstill, simultaneously owing to make fiber produce vibration under the effect at dusty gas air-flow power that passes through or sharp the pushing away of external force, strengthened conflicting of dust in water smoke droplet and the dusty gas, improved fine dust (less than 10 μ m) capture rate, simultaneously because vibration has also improved the self-purification capacity of fiber.Dusty gas through vibratory string filter (4) has become the mixture that contains moistening powder dust particle of water smoke and dust group, a part falls to flowing to sewage draining exit because of deadweight with water curtain, a part is collected to sewage draining exit (7) through separating and dehydrating device (5) separation, thereby be purified gas, Purge gas is discharged from purified gas outlet (6).

This vibratory string filter (4) is to be wrapped in the last cocurrent and parallel arrangement of framework (9) by small diameter fiber (10) to be the palisade curtain, can regulate arbitrarily with layer fiber and interlayer fibre gap.Vibratory string filter (4) can be the assembly of one or a few blocks during installation, can also can closely be arranged in parallel at interval, and adjacent two filter machine directions can be arranged in the same way, but also arranged crosswise.

When being used for boiler dusting, inside and outside wall can be protected with the anticorrosion antiwear protective layer as this device.

Distinguishing feature of the present utility model is:

1, the dust concentration scope that is suitable for is big, the granularity of dust scope is wide, and is fabulous to coal dust, rock dirt and cement dust adaptability;

2, the vibratory string filter self-purification capacity in this device is strong, does not need frequent cleaning, continuous operation for a long time.

3, this apparatus structure is simple, volume is little, in light weight; The installation site flexibility is big, can be connected to the air inlet side of air-introduced machine or the side of giving vent to anger arbitrarily, vertical, horizontally all can.

4, as using its efficiency of seizing dust of air-introduced machine to be directly proportional with wind speed by the vibratory string filter.

Claims

1, a kind of wet type vibratory string dust trapping device that adopts the steel plate welding to form by supply channel, gas feed, waterfog head, separating and dehydrating device, purified gas outlet, sewage draining exit, metal shell, it is characterized in that vibratory string filter that it was positioned on the air inlet sidewind passage and can shelters from whole sections is to be wrapped on the framework cocurrent and parallel by small diameter fiber to arrange and be the palisade curtain, can regulate arbitrarily with layer fiber and interlayer fibre gap.
