Abstract
The utility model relates to a tail gas dust-removing device for an air flow dryer. The tail gas dust-removing device for the air flow dryer comprises a dust-removing box, an induced draft fan connected with the dust-removing box, the outlet end of the induced draft fan is connected with a buffering tank, and a dust-removing tower is arranged on the buffering tank. After first dust removing is conducted on the tail gas with dust of the air flow dryer by the dust-removing box, the tail gas is sent into the dust-removing tower by the induced draft fan, second dust removing is conducted on the tail gas by the induced draft fan to ensure that dustiness of discharged tail gas reaches the approval standard, and the tail gas dust-removing device for the air flow dryer is environmentally-friendly and free of pollution, and can effectively reduce loss of materials.
Description
Technical field
The utility model relates to the chemical pharmaceutical field, relates in particular to a kind of pneumatic drier tails dedusting device.
Background technology
Pneumatic drier is to integrate continuous drying equipment dry, that pulverize, sieve, be specially adapted to the drying of powdery or the graininess wet stock in chemical pharmaceutical field, its operation principle is that hot-air is by entering the annular gap of drying tower bottom to wind apparatus, and helical form rises, simultaneously, wet stock quantitatively adds in the drying tower by charging mechanism, and carry out sufficient heat exchange with hot-air, big wet material is broken under the effect of intensifier, the low less material of granularity that reaches of moisture content rises in the lump with swirling eddy, is delivered to the air draft material collecting device.Yet, in the pneumatic conveying drying process, can produce the tail gas that contains dust, this tail gas is general direct, and dedusting is not thorough by dust cleaning case emptying behind air-introduced machine, still can cause dust pollution, not environmental protection.
The utility model content
The utility model has overcome the deficiencies in the prior art, and a kind of dedusting pneumatic drier tails dedusting device completely is provided.
For achieving the above object, the technical solution adopted in the utility model is: a kind of pneumatic drier tails dedusting device, comprise dust cleaning case, the air-introduced machine that is connected with described dust cleaning case, the port of export of described air-introduced machine is connected with surge tank, on the described surge tank gas wash tower is installed.
In preferred embodiment of the utility model, pneumatic drier comprises further with the tails dedusting device and is provided with the plastic filler layer in the described gas wash tower that the upper end of described gas wash tower is connected with blast pipe.
In preferred embodiment of the utility model, pneumatic drier comprises further that with the tails dedusting device filler in the described plastic filler layer is plastics multiaspect hollow ball filler.
In preferred embodiment of the utility model, pneumatic drier comprises further that with the tails dedusting device bottom of described surge tank is provided with blowoff valve.
In preferred embodiment of the utility model, pneumatic drier comprises further that with the tails dedusting device side upper and lower side of described surge tank is equipped with liquid level gauge.
In preferred embodiment of the utility model, pneumatic drier comprises further that with the tails dedusting device upper end of described surge tank is provided with the absorption liquid import.
The utility model has solved the defective that exists in the background technology, the utility model with the dust-laden tail gas of pneumatic drier after dust cleaning case dedusting for the first time, be sent to by air-introduced machine and carry out the dedusting second time in the gas wash tower, the dustiness that guarantees discharging tail gas reaches criterion of acceptability, environment friendly and pollution-free, and effectively reduce the loss of material.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the structural representation of preferred embodiment of the present utility model;
Among the figure: 1, dust cleaning case, 2, air-introduced machine, 3, surge tank, 4, gas wash tower, 5, the plastic filler layer, 6, blast pipe, 7, blowoff valve, 8, the absorption liquid import, 9, liquid level gauge.
The specific embodiment
In conjunction with the accompanying drawings and embodiments the utility model is described in further detail now, these accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
As shown in Figure 1, a kind of pneumatic drier tails dedusting device comprises dust cleaning case 1, the air-introduced machine 2 that is connected with dust cleaning case 1, and the port of export of air-introduced machine 2 is connected with surge tank 3, and 3 are equipped with gas wash tower 4 on the surge tank.
For the ease of stopping dust in the tail gas, be provided with plastic filler layer 5 in the gas wash tower 4, the filler in this plastic filler layer 5 is plastics multiaspect hollow ball filler, and specific area is big, and blocking effect is strong, and the upper end of gas wash tower 4 is connected with blast pipe 6.
The bottom of surge tank 3 is provided with blowoff valve 7, and the upper end of surge tank 3 is provided with absorption liquid import 8 simultaneously, can inject new absorption liquid.
One side upper and lower side of the preferred surge tank 3 of the utility model is equipped with liquid level gauge 9, can measure the liquid level of absorption liquid in the surge tank 3.
Operation principle of the present utility model is as follows:
The dust-laden tail gas that pneumatic drier is discharged at first enters in the dust cleaning case 1, can remove most particulate dust, the port of export by air-introduced machine 2 enters in the surge tank 3 then, the barrier effect of filler in the plastic filler layer 5 of the dust of tail gas in gas wash tower 4 and dropping in the surge tank 3, the absorption liquid that is cushioned in the jar 3 absorbs, particulate dust residual in the tail gas is removed, and the blast pipe 6 of qualified tail gas on gas wash tower 4 is disposed in the atmosphere.
Above foundation desirable embodiment of the present utility model is enlightenment, and by above-mentioned description, the related personnel can carry out various change and modification fully in the scope that does not depart from this utility model technological thought.The technical scope of this utility model is not limited to the content on the specification, must determine technical scope according to the claim scope.
