Description
Technical field:
The utility model relates to Industrial Boiler and industrial furnace smoke dust-removing desulfurization equipment technical field, is specifically related to a kind of flue gas even pressure type cleaner.
Background technology:
Existing deduster is 91228253.3 " Ma stone double flushing deduster " as number of patent application, and the high efficiency dedusting with more than 99% makes dust content at 20000mg/nm
3Above flue gas, dust exhausting concentration is at 100mg/nm after the dedusting
3Below, occupy high-effect first place at the deduster ranks.But the weak point of this deduster is: two ponds are arranged, take up an area of greatly, and inconvenient operation, ash discharge cost height, the drum dewatering device takes up an area of big, and the water of deviating from has a little environmental pollution.In addition, the length of its dust removing effects and deduster has direct relation, and its dust removal mechanism belongs to " dimension dedusting ", and the dedusting drag overall is big.
The utility model content:
The purpose of this utility model provides a kind of flue gas even pressure type cleaner, and it is on the basis that keeps the existing dust removing effects of deduster, and the dedusting resistance is lower, takes up an area of littler, volume is littler, it is better to operate easier while desulfurized effect.
In order to solve the existing problem of background technology, the utility model is by the following technical solutions: it comprises housing and ashpit, it also comprises into mouth, the water injection nozzle group, the dense smoke district, the dedusting grid, the dedusting work water surface, the first dehydration grid, the second dehydration grid, exhaust opening, overfall and gravity ash-valve, exhaust opening is arranged on the housing upper end, the exhaust opening lower end is provided with the dense smoke district, upper end, dense smoke district is provided with the water injection nozzle group, water injection nozzle group lower end is provided with into mouth, enter the mouth lower end and be provided with the dedusting grid, in the dense smoke district, be respectively arranged with the second dehydration grid and the first dehydration grid between following two ends and the inner walls, the lower end of housing is provided with ashpit, ashpit one side upper end is provided with overfall, the overfall lower end is the dedusting work water surface, and ashpit one side lower end is provided with the gravity ash-valve.
Described housing is with numb one-tenth made of stones.
The utility model improves existing wet dust collector, in its dense smoke district the dedusting grid being set all presses flue gas, flue gas adopts spray dedusting for the first time and makes flue gas cool-down before grid, flue gas flows through the dedusting grid, under grid, produce spray dedusting for the second time, water-bath dedusting for the third time more simultaneously obliquely in deduster water-bath rear space is provided with one to several graticule mesh shape dehydration grid assisted dust-collecting and dehydration.Dehydration grid number is generally at one to five time.
The utility model is on the basis that keeps the existing dust removing effects of deduster, and the dedusting resistance is lower, takes up an area of littler, volume is littler, it is better to operate easier while desulfurized effect.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
The specific embodiment:
With reference to Fig. 1, this specific embodiment is by the following technical solutions: it comprises housing 11 and ashpit 12, it also comprises into mouth 1, water injection nozzle group 2, dense smoke district 3, dedusting grid 4, the dedusting work water surface 5, the first dehydration grid 6, the second dehydration grid 7, exhaust opening 8, overfall 9 and gravity ash-valve 10, exhaust opening 8 is arranged on housing 11 upper ends, exhaust opening 8 lower ends are provided with dense smoke district 3,3 upper ends, dense smoke district are provided with water injection nozzle group 2, water injection nozzle group 2 lower ends are provided with into mouth 1, enter mouth 1 lower end and be provided with dedusting grid 4, in the dense smoke district 3, be respectively arranged with the second dehydration grid 7 and the first dehydration grid 6 between following two ends and housing 11 inwalls, the lower end of housing 11 is provided with ashpit 12, ashpit 12 1 sides upper end is provided with overfall 9, overfall 9 lower ends are the dedusting work water surface 5, and ashpit 12 1 side lower ends are provided with gravity ash-valve 10.
The numb one-tenth made of stones of described housing 11 usefulness.
This specific embodiment comprises the wet dust collector that a Daepori is logical, adopts spray as dedusting for the first time, and makes flue gas cool-down, guarantees that numb stone can be used for the industrial furnace of extra-high-speed temperature.Dedusting grid 4 and the first dehydration grid 6, the second dehydration grid 7 flow flue gas and all press in deduster and advance, and not causing crowded flowing, and do not constitute the dead angle, and evenly dedusting separates with aqueous vapor in whole deduster volume.So just can adopt low flow velocity dedusting to reduce the dedusting resistance, in other words be to adopt " volume dedusting " mechanism.
The course of work of this specific embodiment is: flue gas enters dense smoke district 3 from advancing mouth 1, atomizing spray is set on the top of entering mouth 1 and dense smoke district 3 chews group 2, makes the flue gas humidifying, is convenient to flue dust and pours in the water and suitably cooling, makes numb stone bond line not produce the crack; The dedusting grid 4 that the useful acid proof slab in the bottom in dense smoke district 3 is made.Its assignment of traffic is inhomogeneous, so that make in the dense smoke district 3 flow velocity even, dedusting grid 4 can adopt graticule mesh shape structure, evoking disorderly spray at its underpart inswept water surface of flue gas level gives a dinner of welcome and forms so-called " flyings grid ", the also available fiber crops of dedusting grid 4 one-tenth horseshoe-shaped structure made of stones, eddy flow sounding principle according to whistle, make water surface top, pond form the spray post promptly so-called " boiling water grid " of horizontal level, flue gas has the process of giving a dinner of welcome twice from flowing through between the spray post and the water surface, dedusting grid 4 have the fabulous effect of giving a dinner of welcome, main dedusting approach for this device, flue gas flows through and then enters the pond behind the dedusting grid and carry out water bath dust-removing, and the flue gas behind the water bath dust-removing has a large amount of water droplets and rises, and the graticule mesh dehydration grid 6 and 7 of the oblique storing of flowing through change the flow velocity directions, the component velocity that water droplet is dived downwards, aqueous vapor is separated.Owing to adopt low flow velocity, so dehydrating effect is good, the flue gas after the dehydration is discharged from exhaust opening 8.Can adopt one or many dehydration grid according to actual needs, get final product for general one to five time.
The efficiency of dust collection of this specific embodiment reaches about 99.9%, and the smoke evacuation dust content is lower than 100mg/nm
3, compare with aforementioned deduster, its volume compact takes up an area of for a short time, dedusting is the volume dedusting in the whole volumes of deduster, flow velocity is low, resistance is little, more convenient operation, desulfurization is better, and is reliable simultaneously, long service life, clean maintenance and use all convenient.
