Abstract
The utility model discloses a dust extraction device in a dry and wet sedimentation type, which is used for smoke prevention and dust removal for kiln furnaces. The utility model comprises a chimney flue connected to a chimney and a draught fan, wherein, a box body is connected in series with the chimney flue; a vertical partition board with an opening is arranged in the box body; a water showering spray head, a dehydration baffle board and a slag bucket are respectively arranged in the box body and on the lower part of the box body; the slag opening on the lower part of the slag bucket is arranged below the water level of a water sealing pool. The utility model has the advantages of simple structure, convenient configuration, low cost, and good effects of flue gas desulfurization and dust removal. In addition, the front part of the chimney flue of the utility model is provided with a heat exchanger which can make hot wind returned back to a kiln furnace and provide hot water; the heat exchanger is used for reducing smoke exhausting temperature, improving the combustion temperature in a kiln furnace and providing available hot water.
Description
The utility model relates to the dried wet deposition formula dust arrester of the clear fume and dust of Industrial Stoves.
The existing employing fixed grate grate firing and the Industrial Stoves of gravity-flow ventilation combustion system, it is low that ubiquity the fuel burn-off rate, and smoke evacuation harmful substance and the high problem of dust concentration have not only been wasted the energy, also exist the severe contamination problem of environment.In order to address the above problem, people design multiple smoke abatement and dust control and improve the device of efficiency of combustion, but itself or complex structure, configuration expense costliness; Or poor effect, can not reach the requirement of saving the energy and eliminating environmental pollution.
The purpose of this utility model is at the problems referred to above, and provide a kind of simple in structure, configuration is convenient, neither needs very big configuration expense, can realize improving efficiency of combustion again, reaches the stove device for eliminating smoke and dust of dust emission standard requirement.
The technical scheme that realizes above-mentioned purpose is: a kind of dried wet deposition formula dust arrester, include by kiln and draw cigarette in the flue of chimney and place flue and the air-introduced machine of chimney joint, it is serially connected with a casing in flue, be provided with vertical in casing and leave in down or in the dividing plate of the last opening that is staggeredly located; The trickle shower nozzle is installed on the wall box between its dividing plate, below casing, is provided with the deslagging bucket in water seal tank; Be provided with in the casing chamber that below with respect to flue outlet, constitutes and be lambdoid dehydration baffle plate by back one dividing plate and casing.
The technical scheme that realizes above-mentioned purpose also comprises: be serially connected with one in the front portion of casing and disposed water coiled pipe, vertical gas, the water heat-exchanger rig of crossing cigarette array pipe and constituting of top configuration by shell, bottom in flue; Top at its heat-exchanger rig is provided with pressure fan and ajutage with respect to a vertical side of crossing cigarette array pipe lateral attitude, and opposite side is provided with hot blast and melts down pipe; Water inlet end at its coiled pipe of the bottom of heat-exchanger rig disposes water pump.
This dust arrester is simple in structure, and configuration is convenient, and expense is cheap, has good dust-removal and desulfurizing effect.Treated smoke emissioning concentration can reach 200-300mg/m
3, satisfy the discharge standard of national requirements for environmental protection.Return for the combustion-supporting and hot water apparatus of kiln because air preheat is set in the front portion of dust arrester, can make stove internal combustion temperature improve 30-60 ℃, the corresponding raising of the burn-off rate of coal 5-10%; And can obtain available hot water easily.
Accompanying drawing is this dried wet deposition formula dust arrester structural representation.
The utility model is described in further detail below in conjunction with drawings and Examples.
Provide as accompanying drawing, this dust arrester comprises by kiln delivers to flue 1 and air-introduced machine 8 in the chimney with flue gas, in flue 1, be serially connected with a casing 2, be provided with the vertical dividing plate of several piece 3 in the casing 2, opening is left in the below or the top of each dividing plate, and its each opening upper and lower position interlaces and forms the flue gas flow path of similar S shape.Trickle shower nozzle 4 in casing is installed on the wall box between its dividing plate, is provided with the taper deslagging bucket 5 in water seal tank 6 below the casing diapire between each dividing plate.Below with respect to flue outlet, be lambdoid dehydration baffle plate 7 by being provided with in back one dividing plate and the body cavity mutually that casing constitutes.When this device used, flue gas entered in the casing along flue, when being many times bent S shapes along dividing plate and passing through, sprayed spraying by shower nozzle, made flue gas desulfurization and dedusting, and the micronic dust that is fallen by water smoke absorption is discharged in the water seal tank through the deslagging bucket.Its deslagging bucket end opening that device struggles against during work as for the horizontal plane in the water seal tank below, to realize the flue gas sealing of slag notch.Provide as accompanying drawing, this device is serially connected with one and disposed water coiled pipe 10, vertical gas, the water heat-exchanger rig of crossing cigarette array pipe 11 and constituting of top configuration by shell 9, bottom in the front portion of casing 2 in flue 1; Top at its heat-exchanger rig is provided with pressure fan 12 and ajutage 13 with respect to a vertical side of crossing cigarette array pipe lateral attitude, and opposite side is provided with hot blast and melts down pipe 14; Water inlet end at its coiled pipe of the bottom of heat-exchanger rig disposes water pump 15.This device can make the high-temperature flue gas that is come out by kiln lower the temperature through coiled pipe the time, and the cold water in the heating tube is for using simultaneously.Flue gas after the cooling was when passing through cigarette array pipe, and the effect of the cold air of sending here via pressure fan and ajutage is further lowered the temperature, and the effect of its flue gas cool-down can alleviate the heat erosion effect of high-temperature flue gas to deduster.In addition, the hot-air after the displacement melts down pipe by hot blast delivers to kiln as the burning air feed, can improve the ignition temperature in the stove greatly, and then improve the efficiency of combustion of its kiln.
