The odor may contain a variety of harmful substances, such as NMHC (non-methane hydrocarbons), particulate matter, NH3 (ammonia), H2S (hydrogen sulfide), HCl (hydrogen chloride), fluoride, etc., as well as high concentrations of odorous substances. These substances not only pollute the surrounding environment, but may also have a negative impact on human health.

[0005] However, the flue gas dust removal and purification device of the incinerator for hazardous waste treatment is not able to purify the odor generated after incineration during the waste gas treatment process, and the odor may contain a variety of harmful substances, such as NMHC (non-methane hydrocarbons), particulate matter, NH3 (ammonia), H2S (hydrogen sulfide), HCl (hydrogen chloride), fluoride, etc., as well as high-concentration odor substances. These substances not only pollute the surrounding environment, but also have a negative impact on human health. If they are not purified, the workers will inhale the odor generated during the incineration of hazardous wastes and affect their health. Utility Model Content

[0006] The utility model aims to provide an odor treatment device for a hazardous waste incinerator, so as to solve the problem in the above-mentioned background technology that the odor generated after incineration cannot be purified.

[0007] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0008] An odor treatment device for a hazardous waste incinerator comprises an incinerator as a whole for treating hazardous waste and a biological filtering mechanism for filtering odor. The upper surface of the incinerator as a whole is connected to an exhaust pipe, and the outer surface of the exhaust pipe is connected to the biological filtering mechanism.

[0012] As a preferred solution of the utility model, the air outlet of the biofilter is connected to an air outlet pipe, and the other end of the air outlet pipe is connected to the outer surface of the exhaust pipe.

[0013] As a preferred solution of the utility model, the outer surfaces of the air intake pipe and the air outlet pipe are sleeved with locking rings, and the locking ring is fixedly installed on one end of the support frame.

[0014] As a preferred solution of the utility model, the air intake pipe is located at the lower end of the solenoid valve, and the air outlet pipe is located at the upper end of the solenoid valve.

[0015] Compared with the prior art, the beneficial effects of the odor treatment device of the hazardous waste incinerator of the utility model are:

[0016] 1. When in use, the waste gas generated during the incineration of hazardous waste will be discharged through the exhaust pipe. If it contains odor components during the discharge process, it will be detected by the electrochemical sensor, and the electrochemical sensor will send a signal to the controller. The controller can control the solenoid valve to close and block the exhaust pipe. At the same time, the biological filtration mechanism will inhale the odor in the exhaust pipe and use microorganisms and bacteria to decompose harmful substances in the waste gas, such as ammonia, sulfide and formaldehyde, thereby reducing the generation of odor and harmful gases. It can prevent the staff from inhaling odor during the incineration of hazardous waste, which provides protection for the health of the staff. The treated waste gas will be transported into the exhaust pipe again for continued discharge, so that the subsequent equipment can carry out the next step of purification of the harmful substances therein.

[0017] 2. Through the design of the blower, biofilter, air inlet pipe, air suction pipe and air outlet pipe, the waste gas in the exhaust pipe is sucked in and purified. The blower can be started to suck in the waste gas blocked by the solenoid valve through the air suction pipe, and the waste gas is discharged into the biofilter through the air outlet of the blower through the air inlet pipe. The biofilter uses microorganisms to degrade organic matter and reduce the concentration of odor in the waste gas. When the odor enters the biofilter, the microorganisms on the biofilm degrade the substances, thereby reducing the emission of these harmful substances, reducing the negative impact on the environment, protecting the ecological environment and human health, and the degraded waste gas will be discharged into the exhaust pipe again through the air outlet pipe.
