The processing system of this embodiment, sweep device 200 through the malleation, the flue gas is collected to the cooperation completion of negative pressure collection device 1 and flue gas storage device 300, the flue gas of collection gets into first fume device 600 in proper order, second fume device 500 carries out the spraying and handles, reach the effect of detaching poisonous and harmful gas in the flue gas, with the emission standard who accords with the environmental protection requirement, can discharge to outdoor, the flue gas after second fume device 500 handles gets into deodorizing device 910 and handles, can further get rid of the gas of irritability smell, reach the effect of removing the flavor.
The positive pressure fan 220 and the negative pressure fan 33 of the embodiment can realize the transportation and collection of the flue gas only by using conventional power, prevent the flue gas from dispersing and rising to escape, and achieve excellent flue gas transportation and collection effects. The power of the negative pressure fan is not required to be increased to improve the flue gas collecting capacity, the energy consumption of a flue gas conveying and collecting system is greatly reduced, and the cost of an enterprise is reduced.
The positive pressure purging device 200 in this embodiment can achieve the effect of adjusting the conveying capacity of the positive pressure purging device 200 by controlling the power of the positive pressure fan, thereby achieving the purpose of adjusting the flue gas conveying distance. In addition, the positive pressure purging device 200 is adopted for flue gas transportation in the embodiment, and the flue gas is collected relative to the negative pressure fan, and transportation at a longer distance (several meters, such as 6-15 meters) can be realized.
While the invention has been described in connection with what is presently considered to be the most practical and preferred embodiment, it is to be understood that the invention is not to be limited to the disclosed embodiment, but on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
