Embodiment 1

[0030] 1) Set the start-up temperature of the heat exchange system at 40°C. The spray liquids of the spray towers at all levels are sodium hypochlorite, sodium hydroxide, water, and sodium hydroxide in sequence; the concentration ranges of the spray liquids are 4%, 2%, and 100% in sequence. %, 6%; the initial spray speed is set to 0.

[0031] 2) After the exhaust gas from the fermentation tank produced in the production process of the fermented Cordyceps powder is separated by the cyclone separator, the non-condensable gas enters the exhaust gas monitoring buffer room equipped with temperature and gas concentration monitoring sensors. According to the monitoring data of the monitoring sensors, the solenoid valve is automatically controlled And the blower selectively passes the non-condensable gas through the heat exchange system, the first-level spray tower system, the second-level spray tower system, the third-level spray tower system, and the fourth-level spray tower system. ...

Abstract

The invention discloses a method for purifying and deodorizing tail gas generated in the production process of fermented cordyceps powder. The method comprises the following steps: separating system tail gas generated in the production process of the fermented cordyceps by a cyclone separator (10), causing non-condensable gas to enter an exhaust gas monitoring buffer room (11) with a temperature and gas concentration monitoring sensor, causing the non-condensable gas to selectively pass a heat exchange system (2), a one-stage spray tower system (4), a two-stage spray tower system (5), a three-stage spray tower system (6) and a four-stage spray tower system (7) through the self-control of a magnetic valve and an air blower according to the monitoring data of the monitoring sensor, removingentrainment in the tail gas reaching the standard through online testing by a reset demister (8), and then discharging through a chimney (9).

Description

Technical field: [0001] The invention belongs to the field of industrial waste gas treatment, and in particular relates to a tail gas purification and deodorization method produced in the production process of fermented Cordyceps powder. technical background: [0002] Chinese cordyceps, Ophiocordyceps sinensis (Berk.) G.H.Sung et al. is the dry body of the sclerotia and stroma formed by Cordyceps fungus parasitizing on the larvae of bat moths. The amount of clinical use is increasing day by day. However, Cordyceps sinensis is only distributed in the alpine meadows at an altitude of 3000-5000m on the Qinghai-Tibet Plateau, which has a special habitat and extremely limited natural resources. Coupled with artificial over-excavation, wild Cordyceps sinensis resources are decreasing year by year. The fermented Cordyceps powder produced by our company is produced by fermentation of the strains isolated from natural Cordyceps by the Institute of Materia Medica, Chinese Academy of ...
