Abstract
A water bath type duster is composed of a water tank, a water bath layer and a porous flue immersed in water. The front end of the flue is provided with meshes communicated with a water bath layer, the upper part of the water bath layer is close to and higher than the horizontal plane, and a filter screen layer consisting of porous plates is arranged in parallel; the shell of the water tank body is provided with a dust-containing airflow inlet which is connected with the flue, and the top of the tank body is provided with a purified airflow outlet. The dust remover is connected to the tail of coal-fired boiler, and the dust concentration of the purified gas flow outlet can be as low as 50 mg/standard meter3Dry air, the smoke blackness is close to zero.
Description
The utility model belongs to wet-scrubbing equipment, relates to a kind of flushing wet dust collector.
Water-bath type dust cleaner of the prior art, be by the central intake pipe air inlet mostly, contained in for example " basic theories of dedusting technology and application " (China Construction Industry Press 1981 version the 533rd page) literary composition, its dedusting method is: the air inlet pipe of ash-laden gas is near the water surface, turn behind the gas shock water surface, make grit because of the inertia submerged; Contained in " cleaner design " for another example (Science and Technology of Shanghai publishing house 1985 version the 371st page) literary composition, its dedusting method is to make air inlet pipe stretch into the water surface, and air-flow impacts through water layer, because of being cleaned and effect of inertia is removed grit.This dual mode all can not make air-flow fully contact with water layer, and the quantity of the spray that gas shock caused, bubble and water droplet is few, makes grit wetting and the bonding effect of growing up is strong inadequately, thus efficiency of dust collection improper be the major defect of this water-bath type dust cleaner.
The purpose of this utility model is that design is a kind of simple in structure, can make dust-contained airflow and water layer fully contact and produce the device of a large amount of bubbles, spray and water droplet, with grit in the strengthening flow by the moistening and bonding process of growing up and finally being removed, thereby further make dust removing effects be improved significantly.
Content of the present utility model is to disclose a kind of like this water-bath type dust cleaner technical scheme, its inscape is: a water tank is arranged, be provided with water-bath layer and flue therein, on its shell, be provided with the dust-contained airflow inlet and the purifying gas flow outlet of joining with described flue, of the present utility model being characterised in that: described flue is to invade the following porous flue of the water-bath layer water surface, has netted sieve aperture at the front end of this flue and communicates with the water-bath layer; Above the water-bath layer, near and exceed horizontal plane, also be arranged with the filter mesh layer of forming by porous plate in parallel; Described purifying gas flow outlet is the water tank top that chimney is installed on described filter mesh layer top.
Basic scheme according to above-mentioned wet dust collector, can also be in the space between described filter mesh layer and the purifying gas flow outlet, be provided with the partition wall of the vertical filter mesh layer and the water surface, thereby constitute the folding smoke-box, so that dust-contained airflow is through reflecting repeatedly by water-bath layer and filter mesh layer.
The utility model has the advantages that: dust-contained airflow enters the water-bath layer through a large amount of apertures on the porous flue, evenly distribute at whole water-bath layer overdraught, air-flow fully contacts with the water-bath layer and realizes being cleaned for the first time, and generation bubble and spray, it Duos tens times than bubble and spray that the central intake pipe mode of known technology produces, multistorey strainer mesh smashes bubble and spray again and produces a large amount of water droplets, so the wetting and sticking works very well of absorption dirt; If the effect of folding smoke-box is arranged again, through secondary or multistage water-bath layer and filter mesh layer, remove small dust remaining in the air-flow repeatedly, then the ability of dedusting and effect can strengthen more.
Accompanying drawing provides specific embodiment of the utility model.
Fig. 1 is a flushing water-bath type dust cleaner structural representation front view (complete section) with a folding smoke-box;
Fig. 2 is the A-A view of Fig. 1.
Water-bath type dust cleaner as shown in the figure, it includes water tank 8, porous flue 1, one-level water-bath layer 2, one-level filter mesh layer 3, folding smoke-box 4, secondary water-bath layer 5, secondary filter mesh layer 6, dust-contained airflow inlet R and purifying gas flow outlet C.What arrow was indicated among the figure is the path of air-flow in deduster.When dust-contained airflow enters from inlet R, when entering one group of water-bath layer 2 via a large amount of apertures 7 on the porous flue 1, be cleaned for the first time, and produce a large amount of bubbles and spray, and impacting on the one-level filter mesh layer 3, bubble and spray break, producing the many little water droplets of numbers of poles combines with the sticking machine of the small dirt in the flue gas, make dirt sticking wetting, grow up, through being provided with the folding smoke-box 4 of partition wall 9, be removed (being precipitated at the bottom of the sea water bath) by effect of inertia again.Through secondary water-bath layer 5 and secondary filter mesh layer 6, another is cleaned and produces a large amount of water droplets to air-flow again, and it is sticking to remove small dirt remaining in the air-flow, gets rid of through outlet C thereby be purified air-flow.
The deduster of this embodiment is installed on the coal-burning boiler afterbody, and ash-laden gas can be lower than 50 milligrams/standard meter through the purifying gas flow dust content of deduster outlet
3Dry air, blackness of exhaustion are zero.In addition, this wet dust collector, mostly what deposit in sea water bath is unburnt carbon granule, can reclaim with coal-fired and mix, burns once more.Contain the coal tar that is cleaned in the sea water bath, can with waste water with coal-fired be that 10: 1 ratio is mixed and burnt in coal-water ratio, thereby deduster does not almost have waste water to cause secondary pollution.
Claims (2)
1, a kind of wet dust collector, a water tank is arranged, be provided with water-bath layer and flue therein, on its shell, be provided with the dust-contained airflow inlet and the purifying gas flow outlet of joining with described flue, of the present utility model being characterised in that: described flue is to immerse the following porous flue of the water-bath layer water surface, has netted sieve aperture at the front end of this flue and communicates with the water-bath layer; Above the water-bath layer near and exceed horizontal plane, also be arranged with the filter mesh layer of forming by porous plate in parallel; Described purifying gas flow outlet is the water tank top that chimney is installed on described filter mesh layer top.
