Abstract

The utility model provides a deduster, which comprises a casing having a gas inlet and outlet thereon and is characterized in that: interlaced clapboard sets are arranged inside the casing. Therefore, when gas enters into the deduster, flow rate slows down due to enlarged circulating sectional area to, thereby realizing sedimentation of dust inside the gas under the action of gravity; meanwhile, arrangement of the clapboard sets makes the dust inside the gas deposit after colliding with the clapboard wall, thereby recycling naphthalene dust, a useful industrial product while reducing serious environmental pollution caused by naphthalene dust. The utility model obtains more than 90 percent recovery rate of naphthalene dust, thereby producing better economic benefit; meanwhile, the deduster has the advantages of simple structure, high safety and reliability, ideal dedusting effect without pipeline blockage and easy removing and collecting of settled dust, thereby having better economic and social benefits.

Description

A kind of deduster

Technical field

The utility model relates to a kind of deduster, especially a kind of deduster of collecting the crude naphthalene dust.

Background technology

Crude naphthalene is a kind of byproduct that extracts from coking production institute producing coal tar.In the production process of crude naphthalene, need to carry out air draft from rotary drum crystallizer exhaust outlet with air exhauster, in the air draft process, can discharge a large amount of naphthalene dust.Because crude naphthalene is a kind of crystalline lens, waves very easily with the wind, causes the naphthalene dust to dance in the air all over the sky, the severe contamination surrounding environment also makes operation, repair apparatus etc. be affected.Naphthalene also is the stronger chemical substance of a kind of excitant simultaneously, and its dust easily sucks in the human body by respiratory tract, and is detrimental to health.Therefore, be necessary fully prior art is improved.

Summary of the invention

For overcoming the deficiency that prior art exists, the utility model provides a kind of deduster, to collect the crude naphthalene dust, reduces its pollution on the environment.

The utility model is realized by following technical proposal: a kind of deduster, comprise the housing which is provided with the gas import and export, and it is characterized in that being provided with in the housing staggered dividing plate group.Thereby make gas passage form sinuate snakelike road, so that after gas enters in it, reduce flow velocity under the effect of dividing plate group, the dust in the gas is stopped with flow velocity by dividing plate to slow down and sedimentation simultaneously.

Described dividing plate group is divided into two groups at least, and the two opposite groups dividing plate shifts to install both sides in housing, the upper and lower end of each dividing plate links to each other with the top of housing, diapire, wherein a side links to each other with the housing corresponding side walls, another side places the housing middle part, so that the housing middle part forms snakelike gas passage.

Described housing is horizontally disposed rectangle or cylindrical shape, and housing one end is located in its gas feed, and gas vent is located at the housing other end.

Described housing sidewall is provided with ash door, so that remove the dust after the sedimentation as required in good time.

Described gas feed links to each other with air inlet pipe, and air inlet pipe is provided with steam-heating pipe, so that make the naphthalene dust fusion of easy crystallization, prevents crystallization dust blocking pipe.

The utility model compared with prior art has following advantage and effect: adopt such scheme, can be after gas enters deduster, because of enlarging, actual internal area slows down flow velocity, make the grit sedimentation under the gravity effect in the gas, while is because of the setting of dividing plate group, make grit and baffle wall collision back sedimentation in the gas, when improving the naphthalene dust environment caused severe contamination, reclaim this useful industrial product of naphthalene dust, the utility model can make the naphthalene dust rate of recovery reach more than 90%, obtained favorable economic benefit, the utility model is simple in structure, and is safe and reliable, dust removing effects, blocking pipe not, the dust after the sedimentation are easy to remove, collect, have high economic benefit and social benefit.

Description of drawings

Fig. 1 is the structural representation of the utility model;

Fig. 2 is the vertical view of Fig. 1.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is described further, is not limited thereto but hold within the utility model.

Deduster housing 1 is horizontally disposed rectangle case, its left end is provided with air inlet 2, air inlet 2 links to each other with air inlet pipe 3, be connected with steam pipe 4 on the air inlet pipe 3, to prevent line clogging, the front of housing 1 is provided with the ash door 5 of removing dust, be provided with two dividing plate groups in the housing 1, wherein a dividing plate group 6 is welded on the lateral wall 11 at interval, and another dividing plate group 7 is welded on the madial wall 12, and position and 6 dislocation of dividing plate group, the upper end of each dividing plate all links to each other with roof 8, and the lower end all links to each other with diapire 10, and the inner 13 of each dividing plate places housing 1 middle part, thereby it is snakelike that gas passage is formed, and the right-hand member of housing 1 is provided with escape pipe 9.Dusty gas is after air inlet pipe 3 enters housing 1, and because of actual internal area enlarges, flow velocity slows down, and makes dust be able to sedimentation, and dusty gas is subjected to the obstruction of dividing plate group simultaneously, makes the collision of dust and wooden partition and sedimentation, and the gas after the dedusting flows out through escape pipe 9.

Claims

1, a kind of deduster comprises the housing which is provided with the gas import and export, it is characterized in that being provided with in the housing staggered dividing plate group.

2, deduster according to claim 1, it is characterized in that described dividing plate group is divided into two groups at least, and two relative dividing plate groups shift to install both sides in housing, the upper and lower end of each dividing plate links to each other with the top of housing, diapire, wherein a side links to each other with the housing corresponding side walls, and another side places the housing middle part.

3, deduster according to claim 1 is characterized in that described housing is horizontally disposed rectangle or cylindrical shape, and housing one end is located in its gas feed, and gas vent is located at the housing other end.

4, deduster according to claim 1 is characterized in that described housing sidewall is provided with ash door.

5, deduster according to claim 1 is characterized in that described gas feed links to each other with air inlet pipe, and air inlet pipe is provided with steam-heating pipe.
