Abstract
The utility model discloses a large combined dust collector system, belonging to technical field of pollution treatment. The utility model aims to provide a high temperature resistant dust collector with large air volume and low cost. The utility model is characterized in that a glass fiber big bag dust collector and an air inlet pipe valve are used for removing dust, and a plenum pulse bag dust collector, a back suction fan and a back suction pipe valve are used for removing ash; the problems of high cost of waste gas treatment and high energy consumption in small metallurgy enterprises and other high pollution enterprises such as carbide metallurgy, large boiler, steel and iron smelting are solved. The utility model has the advantages of low cost, low energy consumption, high dust removal and treatment performance, and applicability to dust removal of various high-temperature flue gas.
Description
Affiliated technical field
The utility model relates to a kind of environmental protection dust arrester, belongs to the dust arrester that industrial atmosphere pollutes the dusty gas that exhausted air quantity is big, temperature is high in processing technology field, the especially industrial production.
Background technology
At present, little metallurgical industry develops rapidly.As everyone knows, little smelter is the enterprise of high energy consumption, high pollution, and its EGT height, discharge capacity are big, and control expense is big.Not only little smelter, large-sized boiler, calcium carbide smelting, coking, industrial silicon and relatively large iron-smelting furnace, converter etc. all belong to this situation.If adopt large-scale air box impulse bag-type dust remover, investment is up to ten thousand yuan of 100-200.Traditional dedusting method adopts the big sack cleaner of glass as main deduster waste gas to be carried out dedusting as shown in Figure 2, adopts the air quantity of cyclone dust collectors 3a as secondary deduster processing back suction wind, carries out deashing.Because the cyclone dust collectors efficiency of dust collection is low, still contain dust in the gas of discharging, the intake stack of having to turn back to main deduster carries out final dusting, causes the increase of energy consumption, and the disposal ability of deduster is reduced.
The utility model content
In order to solve the deficiency of traditional deduster, the utility model is a large-scale combined deduster system, form by big sack cleaner 1, back suction blower fan 2, air box impulse bag-type dust remover 3, air inlet 7 is connected with big sack cleaner 1 by intake stack valve 8, big sack cleaner 1 is connected with air box impulse bag-type dust remover 3 to back suction airduct road 5 through back suction air valve 4 again, and air box impulse bag-type dust remover 3 is connected with back suction blower fan 2 again.
The purpose of this utility model provides a kind of large-scale combined deduster system, basic principle be with the big sack cleaner of glass as main frame, the dusty gas of atm number is concentrated (adopt the inward flow filtration-type filter type, dusty gas is filtered); Carry out reversed bay-type deashing as secondary machine in conjunction with the back suction blower fan with air box impulse bag-type dust remover again, unload ash again, reach the purpose of dedusting.Promptly send in the big sack cleaner 1 of glass by blower fan 11, finished the filter process of first step dusty gas from dusty gas; Close intake stack valve 8 by automatic controller, open back suction airduct road valve 4 and air-introduced machine 2, the dust that retains on the cloth bag 8 returns ash bucket 6 with back suction general mood stream, finishes the second step deashing process; Dusty gas after concentrating enters in the air box impulse bag-type dust remover 3 under the effect of back suction blower fan 2, by it this gas is done the secondary filter dust removal process, and dust is separated and draw off, and pure air is emptying once more; Finished for the 3rd step and unloaded grey process.
The beneficial effects of the utility model are, not only can handle a large amount of high temperature dust gases, and eliminate air circulation, and reduce cost, have saved the energy, have improved efficiency of dust collection and disposal ability.
Description of drawings
Fig. 1 is the utility model syndeton schematic diagram;
Fig. 2 is prior art (the big sack cleaner of a glass) syndeton schematic diagram;
Fig. 3 is the utility model host work view;
Fig. 4 is the utility model main frame deashing view.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further specified.
Large-scale combined deduster system, air inlet 7 is connected with the big sack cleaner 1 of glass by intake stack valve 8, the big sack cleaner 1 of glass is connected with PPC32-6 type air box impulse bag-type dust remover 3 to back suction airduct road 5 through back suction air valve 4 again, and air box impulse bag-type dust remover 3 is connected with 9-19 series air-introduced machine (2) again.
Shown in Fig. 1,3: send into intake stack 9 by blower fan 11 from the dusty gas that dusty gas takes place to discharge the source 12 (as metallurgical furnace), intake stack valve 8 unlatchings this moment, dusty gas enters in the ash bucket 6 of the big sack cleaner 1 of glass by air inlet 7, by ash bucket 6, enter in the cloth bag 10, pure air sees through cloth bag 10 and enters in the atmosphere, and dust is stayed in the cloth bag 10; Finished the filter process of first step dusty gas.
As shown in Figure 4: when stockpiling a certain amount of dust in the cloth bag 10, the resistance of cloth bag 10 increases, and need deashing this moment, could guarantee cloth bag 10 operate as normal.Close intake stack valve 8 by automatic controller, open back suction airduct road valve 4 and air-introduced machine 2, this moment, cloth bag 8 was because back suction wind action and sunken, the dust that retains on the cloth bag 8, return ash bucket 6 with back suction general mood stream, and enter back suction airduct road 5, owing to concentrated all dust in the cloth bag, the gas dust content of this moment is higher, is the process of once concentration; Finished the deashing process of the second step deduster.
Dusty gas after concentrating enters in the air box impulse bag-type dust remover 3 under the effect of back suction blower fan 2, by it this gas is done the secondary filter dust removal process, and dust is separated and draw off, and pure air is emptying once more; Finished the grey process of unloading of the 3rd step deduster.
The big sack cleaner 1 of glass is made up of 20 little case chambers and ash bucket 6 thereof, and there are 48 cloth bags 10 each little case chamber, and the air quantity of each little case chamber and ash bucket 6 thereof is about 10-15Km
3/ h, it is 200-300Km that whole system is handled air quantity
3/ h, handling air quantity with one is 15Km
3The air box impulse bag-type dust remover 3 of/h gets final product.
In conjunction with the accompanying drawings the specific embodiment of the present utility model has been carried out exemplary description above, obviously the utility model is not limited thereto, and the various remodeling that carry out in the utility model scope all do not exceed protection domain of the present utility model.
