Detailed ways

The technical solutions of the present utility model will be further described in detail below in conjunction with the specific embodiments, but do not constitute any limitation to the present utility model.

1 to 2, an odor treatment system of the present invention includes an odor incinerator 1. The odor incinerator 1 is provided with a steam outlet 1a and an odor inlet 1b, and the steam outlet 1a passes through a steam pipe 2 are connected with a vacuum ejector 3 and a CNCG ejector 4, respectively. Since the odor incinerator 1 will generate a large amount of thermal energy during the incineration process, in order to utilize the thermal energy reasonably, the odor incinerator 1 is provided with a steam outlet 1a, and the steam generated during the incineration process enters through the steam pipe 2 respectively. Vacuum ejector 3 and CNCG ejector 4, the inlet end of vacuum ejector 3 is also connected with odor pipe 5. A water seal groove 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 pipe 5 enters the water seal groove 6 through the vacuum ejector 3 under the action of steam, so that the odor is eliminated. The non-condensable gas in the gas is separated out, thereby forming a strong odor (CNCG). A separator 7 is connected to the outlet end of the CNCG injector 4, and the separator 7 is communicated with the odor inlet 1b. Under the action of steam, the thick odor enters the separator 7 through the CNCG injector 4, so that the moisture in the thick odor is separated. , and then enter the odor inlet 1b on the odor incinerator 1 for incineration. Both the vacuum ejector 3 and the CNCG ejector 4 use a ZS type steam ejector, and the separator 7 adopts a droplet separator. The odor treatment system makes full use of the heat energy generated by the odor incinerator 1 during the incineration process, and provides sufficient pressure for the odor to enter the odor incinerator 1 through steam, thereby effectively saving the use cost.
