Description
Technical field
The utility model includes non-ferrous metal smelting exhaust purified treatment, is specifically related to a kind of lead blast furnace smoke eliminator.
Background technology
At present, plumbous smelting exhaust content of sulfur dioxide is high, also contains the granule dust of a large amount of utilities, unprocessed direct discharging, and both contaminated environment, the utility in the tail gas also can not get reclaiming, and causes the wasting of resources.
Summary of the invention
The technical problem that the utility model will solve provides a kind of lead blast furnace smoke eliminator.Flue gas after this apparatus processes can directly discharge, and is free from environmental pollution, can reclaim the utility in the tail gas simultaneously.
The technical scheme of the utility model is: a kind of lead blast furnace smoke eliminator, form by first order desulfurizing tower, second level desulfurizing tower and air-introduced machine; Every grade of desulfurizing tower internal structure is identical, the identical shower water circulatory system of outer separate connection one cover of tower; The lead blast furnace exhanst gas outlet is through the air inlet of tracheae connection first order desulfurizing tower, and the gas outlet of first order desulfurizing tower is through the air inlet of tracheae connection second level desulfurizing tower, and the gas outlet of second level desulfurizing tower connects air-introduced machine through tracheae.
The body of the tower of described first order desulfurizing tower or second level desulfurizing tower is cylindric; There is air inlet the body of the tower following side and draws the air inlet pipe that connects the body of the tower outside; The tower body top is shrunk to taper; The vertex of a cone is exhaust outlet and draws the blast pipe that connects on the cat head, and the tower body bottom is a square collecting tank, and blow-off pipe is arranged at the collecting tank bottom.
The described shower water circulatory system is made up of precipitate and separate pond, water circulating pump and spray head; The collecting tank of described first order desulfurizing tower or second level desulfurizing tower is connected with the precipitate and separate pond through blow-off pipe, and the spray head of middle and upper part in first order desulfurizing tower or the second level desulfurizing tower introduced the water in the precipitate and separate pond by water circulating pump through shower.
Said water circulating pump is controlled by automatic control switch.
The utility model adopts the two poles of the earth desulfurizing tower series connection, utilizes water curtain to absorb dedusting; The sediment in precipitate and separate pond contains a large amount of utilities, can reclaim; The utlity model has simple in structure, cost is low, easy to operate, characteristics such as the dedusting pure qi (oxygen) is effective.
Description of drawings
Fig. 1 is the utility model structural representation
In the accompanying drawing: 1 first order desulfurizing tower; 2 second level desulfurizing towers; 3 air-introduced machines; The air inlet of 4 first order desulfurizing towers; The gas outlet of 5 first order desulfurizing towers; The air inlet of 6 second level desulfurizing towers; The gas outlet of 7 second level desulfurizing towers; 8 collecting tanks; 9 blow-off pipes; 10 precipitate and separate ponds; 11 water circulating pumps; 12 spray heads; 13 showers.
The specific embodiment
Below be the utility model to be made further of concrete embodiment with reference to accompanying drawing to explain.
Can know that in conjunction with Fig. 1 the utility model is made up of first order desulfurizing tower 1, second level desulfurizing tower 2 and 3 of air-introduced machines; Every grade of desulfurizing tower internal structure is identical, the identical shower water circulatory system of outer separate connection one cover of tower; The lead blast furnace exhanst gas outlet is through the air inlet 4 of tracheae connection first order desulfurizing tower, and the gas outlet 5 of first order desulfurizing tower is through the air inlet 6 of tracheae connection second level desulfurizing tower, and the gas outlet 7 of second level desulfurizing tower connects air-introduced machine 3 through tracheae.The body of the tower of described first order desulfurizing tower 1 or second level desulfurizing tower 2 is cylindric; There is air inlet the body of the tower following side and draws the air inlet pipe that connects the body of the tower outside; The tower body top is shrunk to taper; The vertex of a cone is exhaust outlet and draws the blast pipe that connects on the cat head, and the tower body bottom is a square collecting tank 8, and blow-off pipe 9 is arranged at the collecting tank bottom.The described shower water circulatory system is made up of precipitate and separate pond 10, water circulating pump 11 and 12 of spray heads; The collecting tank of described first order desulfurizing tower 1 or second level desulfurizing tower 2 is connected with precipitate and separate pond 10 through blow-off pipe, and the spray head 12 of middle and upper part in first order desulfurizing tower 1 or the second level desulfurizing tower 2 introduced the water in the precipitate and separate pond 10 by water circulating pump 11 through shower 13.Said water circulating pump 11 is controlled by automatic control switch.
The utility model operation principle is following:
When the lead blast furnace flue gas gets into the air inlet 4 of first order desulfurizing tower through tracheae; Bulky grain in the flue gas leans on gravitational settling to separate tank 10; The flue gas that continues to rise runs into the water curtain of spray head 12 ejections; Fine particle in the flue gas and sulfur dioxide are absorbed by the spray liquid in the water curtain, and separate tank 10 is collected spray liquid and entered in the precipitate and separate pond 10 through blow-off pipe 9.The tail gas that is not absorbed by first order desulfurizing tower; The gas outlet 5 of under the dynamic action of air-introduced machine 3, passing through first order desulfurizing tower gets into the air inlet 6 of second level desulfurizing tower along pipeline; Tail gas is further absorbed by spray liquid in second level desulfurizing tower 2; Equally, the separate tank in the desulfurizing tower of the second level is collected spray liquid also through entering the precipitate and separate pond from blow-off pipe.The tail gas of desulfurizing tower 2 spray cleanings is discharged through chimney by air-introduced machine again through the second level.Return spray head 12 except that the mixed liquor behind the sediment through water circulating pump 11 through above-mentioned precipitate and separate pond 10 in addition and do to continue spray, recycle.
