Abstract
The utility model discloses a combined dust arrester for dust-contained smoke, which is a dust arrester for dust-contained smoke used for industrial enterprises. The dust arrester for dust-contained smoke is composed of a barrel body of which the top and bottom presents a conical shape, an inlet pipe, a discharge pipe, a water supply system, a slag water discharge facility, and a rotational flow device and a spray device which are arranged in the barrel body, etc., wherein, the rotational flow device is arranged on the lower part in the barrel body, and the spray device is arranged in the middle part of the barrel body. A nozzle of each spray device in each group sprays the water upwards, and a layer of grids which makes water spray easily atomized is respectively arranged above the nozzle and the upper part of the barrel body. The combined dust arrester for dust-contained smoke uses the rotational flow, the spray and a water film effect to remove the dust. The combined dust arrester for dust-contained smoke has the advantages of high efficiency, simple structure and easy application.
Description
The utility model is a kind of composite type dust-precipitator with eddy flow, spraying and moisture film effect, is used for the dedusting of industrial enterprise's ash-laden gas.
At present, the kind of dust-precipitator is a lot, and the dust-collecting efficiency of dust-precipitator simple in structure is generally all below 90%, for example roto-clone, moisture film dust-precipitator; The dust-collecting efficiency of baroque dust-precipitator is generally all below 98%, for example filter bag dust-precipitator, irrigated precipitator.
It is a kind of simple in structure that the purpose of this utility model is to provide, the dust-precipitator that efficiency of dust collection is high again, and to remove dust and the harmful substance in industrial enterprise's ash-laden gas, recyclable utility reduces environmental pollution simultaneously, helps environmental protection.
Ash-laden gas dust-precipitator provided by the utility model, it has microscler cylindrical shell, preferably a circular cylinder body.Its bottom and top are tapered, and a gate and deslagging, water pipe are installed under the base cone, and addendum cone connects blast pipe, and the barrel shell bottom is provided with door to access and band presses ash-laden gas to enter pipe.The bottom is equipped with one group of swirl-flow devices that makes band pressure ash-laden gas become eddy current in the cylindrical shell, top is provided with sprayer unit, its quantity preferably adopts 2～3 groups, the nozzle of every layer of sprayer unit is shower nozzle, upwards sprays water, and water (flow) direction is consistent with the flow direction of flue gas in the cylindrical shell, can reduce gas-flow resistance, help flowing of flue gas, the top in 450～600 millimeters places, the top of the nozzle of every group of sprayer unit and the cylindrical shell is provided with 6～10 purpose grid one decks, so that water spraying atomization.The material of grid is stainless steel or engineering plastics preferably, offer 2～3 peep holes on every layer of corresponding cylindrical shell of spray nozzle device, with the water spraying atomization in the observation cylindrical shell and the corrosion situation of grid.The outer middle part of cylindrical shell is provided with the water system that supplies swirl-flow devices and sprayer unit to use, and its hydraulic pressure is 2～4kgf/Cm
2, it comprises water inlet pipe, gate, annular water-main and passes the branching pipe that barrel is equipped with nozzle on it.
Band presses ash-laden gas to enter from the cylindrical shell bottom, becomes eddy current through swirl-flow devices, discharge from blast pipe by sprayer unit, and blast pipe preferably is connected with the exhaust main that other feeds chimney, catches the mist device otherwise need establish in the gas extraction system again.Dust in the band pressure ash-laden gas and harmful substance and utility are big in the effect of eddy flow, the overwhelming majority is adsorbed by spraying and moisture film, down to the cylindrical shell bottom, regularly be disposed to sedimentation basin through gate and deslagging water pipe with current then, row is handled and comprehensive the recovery again.
Pressing ash-laden gas to enter on pipe and the blast pipe at band respectively is provided with a measured hole, so that detect the data before and after the flue gas dust collection, draws dustiness, thereby calculate dust-collecting efficiency.
The utility model is owing to have the comprehensive effect of eddy flow, spraying and moisture film, thus more much higher than the dust-collecting efficiency of original single effect, and simple in structure, implement easily, good in economic efficiency.
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the front view of composite type ash-laden gas dust-precipitator.
Fig. 2 is the front view and the vertical view of eddy flow plate.
Fig. 3 is the water pipe and the nozzle plane layout drawing of sprayer unit.
It with reference to Fig. 1 the utility model middle part diameter 500 millimeters cylindrical shell (2), it is fixed on the basis by metallic support, its underpart circular cone is installed a Dg50 stop valve (11) down, deslagging water pipe (12) that leads to sedimentation basin of its following connection, barrel shell bottom diameter of installation is that 159 millimeters band presses ash-laden gas to enter pipe (10) and cleaning eye (9), and diameter of upper cone connection is 133 millimeters a blast pipe (1).One group of swirl-flow devices is installed in the bottom in the cylindrical shell, and it is made up of eddy flow plate (8) and water pipe (7), and eddy flow plate (8) enters (10) 1500 millimeters of pipes apart from the bottom flue gas.Eddy flow plate (8) top is provided with two groups of sprayer units, it is by a water inlet pipe, an annular conduit, 3 nozzles and one 6 purpose stainless steel grid are formed, the water pipe of following group sprayer unit is apart from (8) 450 millimeters of eddy flow plates, two groups of sprayer units are at a distance of 985 millimeters, respectively there are 3 to be seedpod of the lotus capitiform, the nozzle (4) that makes progress and spray water, be drilled with diameter on it and be 1 millimeter 5 in hole, the grid of two groups of sprayer units (3) is respectively 540 millimeters and 550 millimeters with the distance of nozzle (4), help water spraying atomization and form moisture film, can reduce mobile group of power of flue gas in the cylindrical shell again, the central space of cylindrical shell internal upper part is laid a grid identical with sprayer unit, and purpose is that water spray is further to atomize in order to make, thereby improves dust-collecting efficiency.The tap water hydraulic that supplies swirl-flow devices and sprayer unit to use is 3kgf/Cm
2, each is regulated with gate, has (14) 2 of peep holes on every group of corresponding cylindrical shell of sprayer unit, with the corrosion situation of water spraying atomization and grid in the observation cylindrical shell.
During work, band presses ash-laden gas to enter from the cylindrical shell bottom, through swirl-flow devices and sprayer unit, and under the effect of eddy flow, spraying and moisture film, dust and SO in the ash-laden gas of zinc leaching dry kiln
2Adsorbed Deng the overwhelming majority by water smoke, flow to the cylindrical shell bottom with water, regular then starting gate (11) flows into sedimentation basin through deslagging water pipe (12), and row comprehensively reclaims utility in waste water neutralisation treatment and the slag again.
Facts have proved that its dust-collecting efficiency can reach more than 99%.
