Summary of the invention
In order to overcome the deficiency in background technology, the utility model discloses a kind of dust hood for blast furnace tap hole,
In order to realize described goal of the invention, this utility model adopts the following technical scheme that a kind of dust hood for blast furnace tap hole, including dust excluding hood housing, smoking pipeline and adsorption filtration room；Described dust excluding hood housing is downward opening horn-type structure, and upper end connects smoking pipeline, and described smoking pipeline connects adsorption filtration room, connects adsorption filtration room and connects smoke pipeline；Described smoking pipeline is provided with anti-return bend；The double-decker that inwall is hollow of described dust excluding hood housing, double-deck hollow space is cover wall flue, and is provided with some air inlets on double-deck internal layer；Being provided with several atomizers in the opening perimeter of described dust excluding hood housing, the shower nozzle of described atomizer is towards the lower section of dust excluding hood housing；Described adsorption filtration indoor are provided with fixed rotating shaft, and described fixed rotating shaft is vertical with the smoking direction of smoking pipeline, and described fixed rotating shaft is fixed on the both sides sidewall of adsorption filtration room by bearing；Described fixed rotating shaft is provided with some adsorbing bars around fixed rotating shaft, described adsorbing bar is provided with adsorbate；Described fixed rotating shaft is additionally provided with wind deflector.
For further improvement opportunity scheme, air inlet described in the utility model is additionally provided with the air inlet guide plate of horn mouth shape towards dust suction chamber side.
For further improvement opportunity scheme, wind deflector described in the utility model is the platy structure of side indent, and one end, long limit of wind deflector is fixed on fixed rotating shaft；Described wind deflector is provided with several, and the concave side of wind deflector is all towards same direction.
For further improvement opportunity scheme, adsorbate material described in the utility model is activated carbon, and described activated carbon is fine strip shape, and every two activated carbons composition opening is outwardly " V " font is fixed on adsorbing bar.
For further improvement opportunity scheme, the lower end of this utility model adsorption filtration room is also devised with liquid oil collecting tank, and liquid oil collecting tank is connected by connecting device with adsorption filtration room, and described connecting device is screw and nut or buckle；The lower end of described adsorption filtration room is additionally provided with the filling mouth of oil guide plate guiding liquid oil collecting tank；Described oil guide plate is the platy structure filling mouth inclination to liquid oil collecting tank.
Owing to have employed technique scheme, this utility model has the advantages that dust hood for blast furnace tap hole described in the utility model, first, the opening perimeter of dust excluding hood housing is provided with several atomizers, the shower nozzle of described atomizer is towards the lower section of dust excluding hood housing, it is possible to flue dust first carries out certain cleaning.For oarse-grained pollutant, under the atomizing of atomizer, directly condense into solid particle.
For entering the flue gas pollutant of dust excluding hood, the cover wall flue of housing can absorb substantial amounts of lightweight flue gas, and the cover wall flue of minor diameter can accelerate the flowing velocity of flue gas, and air inlet guide plate can increase the smoking capacity of cover wall flue.The flue gas that the film sucked for cover wall flue and dust suction chamber suck, enter adsorption filtration room and carry out adsorption filtration, flue gas is adsorbed by the adsorbate of adsorption filtration indoor, wind deflector is under the action of the forces of the wind, produce windage, and then make fixed rotating shaft rotate, it is possible to make the uniform adsorption particle pollutant of adsorbate, activated carbon composition opening is outwardly " V " design of font is to increase adsorption area, better adsorption fouling thing.
It addition, flue gas from tapping hole out time there is significantly high temperature, have in the adsorption process of adsorption filtration room substantial amounts of liquid oil condense, liquid oil condense after by oil guide plate enter liquid oil collecting tank regularly process.
