Description
Technical field
The utility model relates to flue dedusting technology field, specifically belongs to a kind of hot-blast stove and adds dust arrester.
Background technology
Hot-blast stove uses and produces more flue gas, for the processing of flue gas.Existing more treatment system; Layout is provided with unreasonable, normally air-introduced machine is arranged at before the liquid cyclone, after the deduster; Air-introduced machine is drawn the high-temperature flue gas of deduster rough dusting like this; High temperature can cause oxide etch to air-introduced machine, causes damage of bearings simultaneously, has significantly reduced the service life of air-introduced machine.Directly be discharged in the air, atmosphere is polluted.
The utility model content
The purpose of the utility model provides a kind of hot-blast stove and adds dust arrester, has overcome the deficiency of prior art, and simplicity of design is rational in infrastructure, and the wind furnace high-temperature flue gas is effectively handled, and has prolonged the service life of equipment such as air-introduced machine.
The technical scheme that the utility model adopts is following:
A kind of hot-blast stove adds dust arrester, comprises hot-blast stove, air-introduced machine, smokejack and back pool, and hot-blast stove is connected on the smokejack through air-introduced machine; Be provided with screen pack in the described smokejack; Screen pack front end smokejack place has outside lug boss, and the lug boss place establishes fountain head, and fountain head is connected to back pool through pipeline; Scribble smooth layer on the smokejack inwall, the smokejack lower end is connected to back pool through pipeline.
Described smooth layer is the dedusting lacquer.
Compared with present technology, the beneficial effect of the utility model is following:
The utility model design is adopted, and through the even water spray of fountain head the particle in the flue is fallen, and again through lower channel, introduces in the back pool.The flue inwall is provided with dustproof lacquer, and particle can not invest on the flue, and dust removing effects is better, and simplicity of design is rational in infrastructure.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Referring to accompanying drawing, a kind of hot-blast stove adds dust arrester, comprises hot-blast stove 1, air-introduced machine 2, smokejack 3 and back pool 4; Hot-blast stove 1 is connected on the smokejack 3 through air-introduced machine 2; Be provided with screen pack 5 in the smokejack 3, screen pack 5 front end smokejacks 3 places have outside lug boss, and the lug boss place establishes fountain head 6; Fountain head 6 is connected to back pool through pipeline 7, and pipeline is provided with water pump 9.Scribble the smooth layer 8 of dedusting lacquer on smokejack 3 inwalls, smokejack 3 lower ends are connected to back pool 4 through pipeline 7.
