Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Fig. 1 is structural representation of the present utility model, as shown in the figure: the air-flow inertia dust trapping device of the present embodiment, comprises the gas permeability filter course and the water curtain that overlap; Described water curtain is located at the back of the body stream side of gas permeability filter course along airflow direction; Gas permeability filter course and water curtain can be fixed together by bonding or stitching, improve gas permeability filter course and the structural stability of water curtain under airflow function; Can adopt suspension type to install or base type installation, so that use and on-the-spot installation; Gas permeability filter course can be sponge or gas permeability filter membrane, for the large dust granules of filtering air-flow; Water curtain is that the granule impurity for adsorption gas flow, also has gas permeability in conjunction with the cord of a kind of immersion of supply line and fiber cloth generation; In process of production, the dust, the steam that produce can be with air-flow disperse in whole tunnels, in the motion of dust with air-flow, because the quality of dust granules, steam is greater than the quality of gas molecule, its inertia is different and be conducive to the separation of dust, steam; The air-flow of dust-laden, mist is injected gas permeability filter course, dirt, mist are through obstruction and the filtration of gas permeability filter course, Speed Reduction and staying in gas permeability filter course, the less grit of part impacts water curtain, bonding by the water of water curtain by gas permeability filter course, thereby reach the effect of dust removal by filtration, the air-flow purifying sees through water curtain and overflows, and in use procedure, only needing provides water source for water curtain, without other power consumptions, in use, can not produce potential safety hazard; Simple in structure, use cost is low, can large area lay; Thereby the dustiness that can reduce in a large number greatly in dirt, the aerial flotation time reduction of mist air-flow because of seizure area reaches the object purifying air; Because the air-flow inertia dust trapping device of the present embodiment is passive unpowered planar body of catching dirt, so placement location should vertically with air-flow be placed in theory, but produce and air-flow is produced to larger resistance because it can not affect, so be positioned over as far as possible windward side, edge grain as large in crook, tunnel, air-flow is subject to the large edge grain of bend constraint directive at this; Air-flow convolution place, as the negative pressure of air duct mouth refluxes; Driving face return to wind place, working face air-flow habitat, the working face etc. of blowing out.
In the present embodiment, described water curtain comprises feed pipe 1 and is fixed on the door curtain made of cloth 2 of feed pipe 1; Described feed pipe 1 is provided with the admission port for the door curtain made of cloth 2 that its inner water is led; Adopting the existing water system being comprised of water pump, water tank and valve etc. to take certain flow can make the door curtain made of cloth 2 keep the states of soaking to form water curtain as feed pipe 1 supplies water; Feed pipe 1 is rigid pipe; The door curtain made of cloth 2 is fiber cloth of the prior art.
In the present embodiment, described feed pipe 1 is horizontally disposed with; Described admission port is to be positioned at the bar hole that feed pipe 1 bottom tube wall is axially offered; The described door curtain made of cloth 2 upper edges are fixedly clamped in bar hole, make to be full of in feed pipe 1 water and just can ooze from top to bottom and be abound with curtain 2 and form water curtains, simple in structure, are convenient to manufacture.
In the present embodiment, described gas permeability filter course comprises a plurality of spongy layers that overlap; The foam hole of each spongy layer vary in size and with foam hole along the descending arrangement of airflow direction, the gas permeability filter course of the present embodiment is by pore sponge 3, compared with pore sponge 4 and 5 three overlapping forming of spongy layer of gross porosity sponge, sponge has good water imbibition, therefore the part water in water curtain can flow to spongy layer and soaked, the air-flow of dust-laden, mist is injected cavernous body, dirt, mist are through obstruction and the filtration in the descending hole of sponge, and cavernous body is in moisture state, Speed Reduction and staying in cavernous body, produces and filters preferably and dust suction effect.
In the present embodiment, described air-flow inertia dust trapping device also comprises installing rack 6 and pedestal 7; Described gas permeability filter course and water curtain are fixed on pedestal 7 tops by installing rack 6; On described pedestal 7, the vertical projection of corresponding gas permeability filter course and water curtain is provided with receipts drainage box, can carry out manual cleaning or above gas permeability filter course, spray head is set automatically cleaning to gas permeability filter course, under the effect of gravity, water and dirt flow into and receive drainage box, be convenient to collect discharge, avoid causing environment wet and slippery, make the air-flow inertia dust trapping device of the present embodiment regain simultaneously and catch dirt ability, reach the object recycling; Installing rack 6 can be that corresponding gas permeability filter course and water curtain surrounding are along the angle steel or the chan frame that arrange.
In the present embodiment, described air-flow inertia dust trapping device also comprise along airflow direction be located at gas permeability filter course meet stream side top at least gas permeability filter course top layer being carried out the sparge pipe 8 of spraying-rinsing, automaticity is high, without labor cleaning and maintenance, make the air-flow inertia dust trapping device of the present embodiment regain simultaneously and catch dirt ability, reach the object recycling; Sparge pipe 8 can be fixedly connected on feed pipe 1, and then shares same water system with feed pipe 1, makes designs simplification; Water curtain is located at gas permeability filter course back of the body stream side and the overlapping laminating of gas permeability filter course, sparge pipe 8 is located at gas permeability filter course and is met between stream side and gas permeability filter course and leave certain distance, make to produce certain angle, raising cleaning performance between current and the gas permeability filter course of ejection.
In the present embodiment, the tube wall of described sparge pipe 8 is a plurality of hole for water sprayings of spread configuration vertically, sparge pipe 8 is parallel with feed pipe 1 and can make the water spray angle of hole for water spraying cover whole gas permeability filter course around its axis rotation, cleans thoroughly, can keep good dust removal by filtration function; Sparge pipe 8 by retainer (not shown) be rotationally connected with installing rack 6 and and feed pipe 1 between by soft pipe connection, by the rotation of motor positive and inverse of the prior art and gear drive sub-control sparge pipe 8.
