Abstract
The utility model discloses a pretreatment device for lead refining smoke. A smoke inlet is arranged at the lower part of a main box body, a smoke outlet is arranged at the upper part of the main box body, a dust removing chamber is arranged in the main box body and above the smoke inlet, more than one layer of filtering devices are arranged in the dust removing chamber, the filtering devices are provided with a plurality of inclined baffles which are used for filtering oily smoke dust, and a dust hopper used for collecting dust is arranged at the bottom of the main box body. The lead refining smoke is firstly pretreated in the pretreatment device, then enters the main box body from the smoke inlet, and then passes through inclined slits on the filtering devices as the dust removing chamber internally adopts the filtering devices formed by inclined baffles, so that the oily smoke dust can be attached on the baffles or struck to rebounded to be gathered with the smoke dust to form large particle sedimentation, and the purified smoke is discharged from the smoke outlet at the upper part of the main box body, then enters a pipeline, and finally enters a bag-type dust removing device for purifying treatment. By using the pretreatment device, the replacing period of the bag-type dust removing device can be prolonged to two years/per time, thus avoiding the problem of over-high maintenance cost.
Description
Technical field
The utility model relates to a kind of plumbous refining filtrating equipment of flue gas.
Background technology
At present, the processing method of plumbous refining flue gas has two kinds, i.e. dry method and wet method.The main equipment that dry method generally adopts sack cleaner to handle as flue gas, wet method then with wet scrubbers such as spray columns as main equipment.Add rosin, NaOH, NaNO in the plumbous refining process
3Deng the flue gas that medicament produces, flue gas oiliness material and flue dust caking property are very strong.Adopt sack cleaner that plumbous refining flue gas is carried out filtration treatment, flue dust in the flue gas bonds on the filter bag easily, is difficult to during deashing flue dust is removed from filter bag, use 2-3 month after, must change filter bag and could guarantee the flue gas treatment effect, filter bag renewal cost and maintenance time are long.
Summary of the invention
Goal of the invention of the present utility model is to provide a kind of cooperation sack cleaner that plumbous refining flue gas is carried out pretreated plumbous refining Flue Gas Pretreatment Device at the above-mentioned deficiency of prior art, can reduce bag-type duster filtering bag and change frequency, reduce the filter bag maintenance cost.
The technical solution of the utility model is: gas approach is arranged at the main box bottom, and exhanst gas outlet is arranged at main box top; There is more than one dirt pocket the top of main box inside, gas approach; Be provided with the above filter of one deck in the described dirt pocket; Described filter is equipped with the some sloping baffles that are used to filter the oiliness flue dust; Described main box bottom is provided with the ash bucket that is used to collect dust.
Described filter is horizontally placed in the dirt pocket.
Described exhanst gas outlet is positioned at the main box upper side.
Described main box is a rectangular structure.
Described dirt pocket is four.
Described ash bucket is a funnel-shaped structure.
Described filter is a frame structure.
Plumbous refining flue gas at first carries out preliminary treatment in the utility model, plumbous refining flue gas enters main box from gas approach, rise then and enter four dirt pockets of main box inside, because the filter that has adopted multilayer to constitute in the dirt pocket by the polylith sloping baffle, flue gas passes through from the R-joining on the filter, the oiliness flue dust is gathered into the bulky grain sedimentation attached on the baffle plate or bump bounce-back back with flue dust, and flue gas after being purified continues to rise and enters main box top.Along with the flue dust that adheres on the baffle plate increases, under the gravity effect of flue dust self, flue dust comes off from baffle plate, falls in the ash bucket below the main box.Flue gas after being purified is discharged from the exhanst gas outlet on main box top and is entered pipeline, enters sack cleaner again and carries out purified treatment.After the utility model was used, the bag-type duster filtering bag replacement cycle extended to 2 years and changes once.

Among the figure, 1, main box, 2, ash bucket, 3, filter, 4, gas approach, 5, exhanst gas outlet, 6, baffle plate.
The specific embodiment
Among Fig. 1, main box 1 profile is a rectangular structure, and internal chiasma is divided into four dirt pockets, and each dirt pocket is provided with multiple filtration device 3.Filter 3 is overall structures, by the steel baffle plate 6 of the long 410mm of polylith, wide 110mm tilt (being 45) with horizontal direction be welded on through arc welding on the framework of long 985mm, wide 420mm, constitute the R-joining of wide 53-55mm between baffle plate and the baffle plate.Main box 1 bottom is an ash bucket 2, is used to collect the flue dust that filters.Ash bucket 2 top main boxes 1 side is provided with gas approach 4, and main box 1 upper side is provided with exhanst gas outlet 5.
Among Fig. 2, Fig. 3, filter 3 is overall structures, steel baffle plate 6 inclinations (being 45 with horizontal direction) by 17 block length 410mm, wide 110mm are welded on the framework of long 985mm, wide 420mm through arc welding, constitute the R-joining of wide 53-55mm between baffle plate and the baffle plate, flue gas passes through from R-joining, and the oiliness flue dust that contains in the flue gas is gathered into the bulky grain sedimentation attached on the baffle plate 6 or bump bounce-back back with flue dust.
Plumbous refining flue gas at first carries out preliminary treatment in the utility model, plumbous refining flue gas enters main box 1 from gas approach 4, rise then and enter four dirt pockets of main box 1 inside, because the filter 3 that has adopted multilayer to constitute in the dirt pocket by polylith sloping baffle 6, flue gas passes through from the R-joining on the filter 3, the oiliness flue dust is attached on the baffle plate 6, and flue gas after being purified continues to rise and enters main box 1 top.Along with the flue dust that adheres on the baffle plate 6 increases, under the gravity effect of flue dust self, flue dust comes off from baffle plate 6, falls in the ash bucket 2 below the main box 1.Flue gas after being purified is discharged from the exhanst gas outlet 5 on main box 1 top and is entered pipeline, enters sack cleaner again and carries out purified treatment.
