Centrifugal clarifier for dust fume
Technical field
The utility model relates to a kind of clarifier for dust fume, particularly relates to a kind of centrifugal clarifier for dust fume, belongs to technical field of environment protection equipment.
Background technology
Produce volume of smoke waste gas while industry high speed development, containing multiple deleterious particle and toxic gas in smoke exhaust, directly discharge causes great pollution to environment; And more existing industrial waste gas purifying treatment facility ubiquity complex structure, the high deficiencies of processing cost, so waste gas is stolen row's phenomenon and is happened occasionally, serious environment pollution.Therefore, simple in the urgent need to a kind of structure, processing cost is low and the off-gas cleaning equipment that treatment effect is good, solves current environment pollution problem.
Summary of the invention
It is simple that the technical problems to be solved in the utility model is to provide a kind of structure, and smoke exhaust processing cost is low and treatment effect good, the centrifugal clarifier for dust fume of more energy-conserving and environment-protective.
For solving the problems of the technologies described above, the utility model adopts so a kind of centrifugal clarifier for dust fume, this clarifier for dust fume comprises a columnar tank body, smoke exhaust air inlet is provided with in the bottom of this tank body, smoke exhaust gas outlet is provided with on the top of this tank body, a hollow rotating shaft arranged along tank body central axis is also installed rotationally in this tank body, this hollow rotating shaft has a blind end and an openend, the openend of described hollow rotating shaft is connected with water-supply-pipe, the tube wall of this hollow rotating shaft offers several radial apopores, this hollow rotating shaft is by motor-driven rotation.
As a kind of preferred embodiment of the present utility model, the inwall of this tank body is provided with a spiral guiding plate.
In the utility model, be also provided with at least one apopore in the bottom of this tank body.
After adopting said structure, the utility model has following beneficial effect:
The parts that the utility model purifier adopts are less, and structure is simple, low cost of manufacture.
The centrifugal current that the utility model purifier is spilt by rotation spray from hollow rotating shaft radial apopore and water smoke carry out purified treatment to smoke exhaust, not only purified treatment is effective, can meet the requirement of waste gas environment protection emission better, and the processing cost of smoke exhaust is cheap.
After the utility model purifier arranges spiral guiding plate in inner tank wall, the purified treatment effect of smoke exhaust is better.
The utility model operationally only need low-power machine drive hollow rotating shaft rotate, the electric energy consumed and the water yield less, greatly reduce energy resource consumption.

Detailed description of the invention
See the centrifugal clarifier for dust fume of the one shown in Fig. 1 to Fig. 3, this clarifier for dust fume comprises a columnar tank body 1, tank body 1 is made up of columnar metal stack shell and the closed cover being positioned at stack shell two ends, this tank body 1 can vertically be arranged, also can be horizontally disposed with, smoke exhaust air inlet 1-1 is provided with in the bottom of this tank body 1, smoke exhaust gas outlet 1-2 is provided with on the top of this tank body 1, a hollow rotating shaft 2 arranged along tank body 1 central axis is also installed rotationally in this tank body 1, this hollow rotating shaft 2 has an a blind end 2-1 and openend 2-2, the blind end 2-1 of described hollow rotating shaft 2 is connected with tank body 1 lower rotation by bearing, the openend 2-2 of described hollow rotating shaft 2 is connected with water-supply-pipe 3, during work, washings are conveyed in hollow rotating shaft 2 by water-supply-pipe 3, the tube wall of this hollow rotating shaft 2 offers several radial apopore 2-3, this hollow rotating shaft 2 drives rotation by motor 4.
As a kind of preferred embodiment of the present utility model, as shown in Figure 1,2 and 3, the inwall of this tank body 1 is provided with a spiral guiding plate 5.After adopting such structure, the smoke exhaust being gathered in spiral guiding plate 5 place fully contacts with centrifugal current and water smoke, thus makes clean-up effect better.
In the utility model, be also provided with at least one apopore 6 in the bottom of this tank body 1, as shown in Figure 1,2 and 3.
Hollow rotating shaft 2 of the present utility model drives rotation by motor 4 by reduction box and belt gear.
The utility model operationally, see Fig. 1 to Fig. 3, smoke exhaust enters in tank body 1 with the air inlet 1-1 of tank body 1 bottom by the road, washings are delivered in hollow rotating shaft 2 through water-supply-pipe 3, when hollow rotating shaft 2 drives rotation by motor 4, washings rotation spray from the radial apopore 2-3 of hollow rotating shaft 2 is spilt, the centrifugal current sprayed and water smoke are by tank body 1 and after the abundant washing, purifying of smoke exhaust being gathered in spiral guiding plate 5 place, the sewage formed flows out from the apopore 6 of tank body 1 bottom, the cleaning formed, the air meeting environment protection emission requirement directly enters air from the gas outlet 1-2 on tank body 1 top.
