Detailed Description

The technical solution of the present invention will be further described in detail with reference to the following detailed description, but the present invention is not limited thereto.

Referring to fig. 1 to 2, the odor treatment system of the present invention comprises an odor incinerator 1, wherein the odor incinerator 1 is provided with a steam outlet 1a and an odor inlet 1b, and the steam outlet 1a is connected to a vacuum ejector 3 and a CNCG ejector 4 through a steam pipe 2. Since the odor incinerator 1 can generate large heat energy during incineration, in order to reasonably utilize the heat energy, a steam outlet 1a is provided on the odor incinerator 1, the steam generated during incineration enters a vacuum ejector 3 and a CNCG ejector 4 through a steam pipe 2, respectively, and an odor pipe 5 is further connected to an inlet end of the vacuum ejector 3. A water seal tank 6 is arranged between the outlet end of the vacuum ejector 3 and the inlet end of the CNCG ejector 4, and the odor in the odor pipeline 5 enters the water seal tank 6 through the vacuum ejector 3 under the action of steam, so that non-condensable gas in the odor is separated out, and thick odor (CNCG) is formed. The outlet end of the CNCG ejector 4 is connected with a separator 7, the separator 7 is communicated with the odor inlet 1b, the thick odor enters the separator 7 through the CNCG ejector 4 under the action of steam, so that the moisture in the thick odor is separated, and then the thick odor enters the odor inlet 1b on the odor incinerator 1 for incineration. The vacuum ejector 3 and the CNCG ejector 4 both employ ZS type steam ejectors, and the separator 7 employs a droplet separator. The odor treatment system fully utilizes the heat energy generated in the incineration process of the odor incinerator 1, and provides enough pressure for the odor to enter the odor incinerator 1 through steam, thereby effectively saving the use cost.

The odor inlet 1b is also connected with an air supply device, the air supply device comprises a fan 8 and a cyclone air port 9 connected with the fan, one end of the cyclone air port 9 is provided with a cyclone pipeline 10, and the cyclone pipeline 10 is communicated with the odor inlet 1 b. The wind generated by the fan 8 forms cyclone wind through the cyclone wind port 9, and then joins with the strong odor formed through the separator 7 through the cyclone pipeline 10, under the effect of the cyclone wind, the strong odor is pushed to enter the odor inlet 1b along the cyclone direction, and then enters the odor incinerator 1 for incineration. The swirling air can not only push the thick odor to enter the odor incinerator 1 to provide air for the incineration of the thick odor, but also prolong the incineration time of the thick odor in the hearth of the odor incinerator 1, so that the thick odor is sufficiently incinerated, and the content of pollutants in the odor is further reduced.

The steam pipeline 2 is respectively provided with a plurality of regulating valves, and the flow rate of the steam in the steam pipeline 2 can be well controlled through the regulating valves. One side of the odor incinerator 1 is provided with a fuel inlet 1c, and natural gas can be introduced into a hearth of the odor incinerator 1 through the fuel inlet 1c, so that combustion supporting of strong odor is realized. The bottom of the odor incinerator 1 is provided with a sewage channel 1d, impurities generated in the incineration process of the odor incinerator 1 can be accumulated and timely discharged through the sewage channel 1d, and the accumulation condition in the odor incinerator 1 is prevented. One side of the odor incinerator 1 is provided with a flue gas outlet 1e, and the flue gas outlet 1e is connected with a flue gas filtering device 12 through a flue gas pipeline 11. Preferably, the flue gas filtering device 12 comprises a water tank 12a and a filter plate 12b, the flue gas duct 11 being inserted in the water tank 12a, the filter plate 12b being helical and being arranged between the inner wall of the water tank 12a and the outer wall of the flue gas duct 11. Because the flue gas contains more large granule dust impurity, if directly discharge these flue gases to the air in, can cause serious air pollution, utilize the heat energy that flue gas itself possessed, the flue gas that will dense foul smell produced in burning process passes through flue gas pipeline 11 and discharges into basin 12a, make the water in basin 12a evaporate, produce steam, the flue gas is along filter 12b spiral rising under the effect of steam, because the downward impact force of flue gas is greater than its buoyancy that rises, consequently, large granule dust impurity in the flue gas can filter in basin 12a by a large amount, utilize this flue gas filter 12 to filter the large granule dust impurity that contains in the flue gas effectively, prevented that the flue gas from directly discharging to the air and the environmental pollution who causes.

Above-mentioned odor treatment system make full use of odor incinerator 1 burn the heat energy that the in-process produced burning, form thick odor and thick odor to get into odor incinerator 1 and provide sufficient pressure after getting into water seal tank 6 for the odor through steam, when guaranteeing that the odor is fully burned, odor treatment system's use cost has been practiced thrift effectively, and flue gas filter equipment 12 has guaranteed the filter effect of the large granule dust in the flue gas, effectively avoided the flue gas directly to discharge to the air and the environmental pollution who causes. Through the odor treatment system, a large amount of odor generated in the pulping process of a paper mill can be effectively treated, so that the environmental pollution is avoided, the odor treatment cost is reduced, and the odor treatment system has great use value.

The above description is only for the preferred embodiment of the present invention, and all modifications, equivalents, improvements and the like made within the spirit and scope of the present invention should be included in the protection scope of the present invention.
