Description
Technical field
Emission-control equipment technical field is the utility model is related to, is related to a kind of vent gas treatment chimney.
Background technology
Chemical plant needs to use the high-temperature services such as calcining furnace when carrying out production at present, and fuel combustion is inevitable
Ground produces substantial amounts of flue dust, contains the materials such as substantial amounts of dust, sulfide, carbon dioxide, the main work of chimney in these flue dust
With being the cigarette that puts a chimney on the stove and make the fire draw, drain flue gas, improve burning condition, it is divided into civilian and industrial again, and household chimney is very simple, main use
In smoke evacuation, industrial chimney is mainly for the waste that is scattered, and reaches certain and pull out wind-force.But chimney has another implication again,
That is Environment pollution, chimney is more, means that the waste gas of discharge is more, it is therefore necessary to which the tail gas of chimney discharge is handled.
Such as Chinese utility model patent publication number CN201520391732.8 discloses a kind of phosphoric acid tail gas processing system, including it is horizontal
Showering washing device (1), Meter Monitor System, exhaust fan (4), chimney (5) and pipeline with exhaust fan to tail gas, it is necessary to be carried
For the power of rising, it is set smoothly to be discharged by chimney, existing vent gas treatment chimney is all this air supply pattern, and tail gas wind
Machine is external to take larger space, and space availability ratio is relatively low, and the power consumption of exhaust fan is larger, be sent into the tail gas meeting of chimney
Very fast to discharge, the objectionable impurities in tail gas cannot be settled fully.
Utility model content
The technical problems to be solved in the utility model is that existing vent gas treatment chimney is made using external exhaust fan
To export power source, high energy consumption, tail gas filtering effect is poor, low space utilization, and a kind of vent gas treatment chimney is provided for this.
The technical solution of the utility model is：Vent gas treatment chimney, it includes chimney body, the chimney body side
Flue is offered close to bottom, the outer bottom of the chimney body is connected with rotating disk, and the inner bottom part of the chimney body is set
There is the hollow rotating shaft with rotating disk linkage, the hollow rotating shaft is externally connected with some rotating vanes being interspersed, the rotation
The free end of rotating vane piece and the inwall of chimney body contradict.
The improvement of such scheme is that the inner concentric of the hollow rotating shaft is connected with filtering mandrel, the hollow rotating shaft
Surface be evenly distributed with gas port group along its length, the gas port group includes circumferentially distributed along hollow rotating shaft outer surface
At least two gas ports.
Gas port described in such scheme is the taper gas port expanded outwardly.
The sector that rotating vane described in such scheme extends horizontally.
It is flexibly connected described in such scheme between rotating vane and hollow rotating shaft.
The beneficial effects of the utility model are to set rotatable hollow rotating shaft to drive flow perturbation inside chimney, and
Barrier cutting is carried out to the air-flow of disturbance using rotating vane so that the tail gas of rising is in spiral shape, can fully settle tail gas
In large granular impurity, and can reduce energy consumption, improve space availability ratio.
Brief description of the drawings
Fig. 1 is the utility model schematic diagram；
In figure, 1, chimney body, 2, flue, 3, rotating disk, 4, hollow rotating shaft, 5, rotating vane, 6, filtering mandrel,
7th, gas port.
Embodiment
Below in conjunction with the accompanying drawings and embodiment is described further to the utility model.
As shown in figure 1, the utility model includes chimney body 1, the chimney body side offers flue gas close to bottom
Pipeline 2, the outer bottom of the chimney body be connected with rotating disk 3, and the inner bottom part of the chimney body is provided with to link with rotating disk
Empty rotary shaft 4, the hollow rotating shaft are externally connected with some rotating vanes 5 being interspersed, the free end of the rotating vane
Contradicted with the inwall of chimney body.
The utility model gives it up traditional exhaust fan, greatlys save space, improves space utilization
Rate, rotated by driven by rotary disc hollow rotating shaft, the driving force of rotating disk can be provided by motor, preferably stepping electricity
Machine, its advantage are that rotating speed is controllable.The height of hollow rotating shaft is substantially suitable with the height of chimney body, can be slightly below chimney sheet
The height of body.
The utility model is elaborated with reference to embodiment.
Embodiment 1：Vent gas treatment chimney, it includes chimney body 1, and the chimney body side offers close to bottom
Flue 2, the outer bottom of the chimney body are connected with rotating disk 3, and the inner bottom part of the chimney body is provided with to link with rotating disk
Hollow rotating shaft 4, be fixedly connected with some rotating vanes 5 being interspersed outside the hollow rotating shaft, the rotating vane is in
Bar shaped, the free end of the rotating vane and the inwall of chimney body contradict.
Embodiment 2：Difference with embodiment 1 is rotating vane in sector, or semicircle, so when rotating vane with
Bigger cutting area will be had by when hollow axle rotates, and can quickly be stirred tail gas, while promote tail gas along rotation
Convoluted flow between blade, holdup time of the increase tail gas in chimney.
Embodiment 3：Difference with embodiment 1 is that the inner concentric of the hollow rotating shaft is connected with filtering mandrel 6, institute
The surface for stating hollow rotating shaft is evenly distributed with gas port group along its length, and the gas port group is included along outside hollow rotating shaft
At least two circumferentially distributed gas ports 7 of surface.So tail gas will have part to enter in gas port, by filtering in gas port
Finally by being discharged in the gas port group of the top after the filtering of mandrel, further cleaning of off-gas, the quantity of gas port group is in
The length of empty rotary shaft determines that the gas port of each gas port group can have 2 or 3 or more, and the shape of gas port is preferred
For the taper gas port expanded outwardly, more tail gas so will be sucked when hollow rotating shaft rotates, improves the mistake of tail gas
Total amount is filtered, the embodiment may apply in embodiment 2.
Embodiment 4：Difference with embodiment 1, which is to be flexibly connected outside the hollow rotating shaft, some rotations being interspersed
Rotating vane piece 5, rotating vane rotation is driven so when hollow rotating shaft rotates, because both are flexible connections, rotating vane will
Can occur it is certain swing up and down, be advantageous to produce raising and lowering air-flow so that tail gas does not disturb only in horizontal direction,
Also disturbed simultaneously in vertical direction, promote the abundant flowing of tail gas.
Workflow of the present utility model is as follows：Band=tail gas to be discharged is directly discharged into chimney sheet via flue
In vivo, the rotation of driven by rotary disc hollow rotating shaft is started, tail gas cuts deflecting in uphill process by rotating vane so that tail gas edge
Hollow rotating shaft to spiral rising, during which partial tail gas is by taper gas port suction hollow rotating shaft, by filtering mandrel
Discharged after filtering outside hollow rotating shaft, it is final to discharge outside chimney body.
