Deodorization system for efficiently applying pesticide and deodorizing by using kitchen waste conveying air duct

The deodorization system comprises an air pipe of an odor air conveying system, one end of the air pipe is connected with an odor collecting opening formed in a place where odor needs to be exhausted, and the other end of the air pipe is connected with an inlet of a deodorization reactor. An outlet of the deodorization reactor is communicated with the atmosphere through an exhaust funnel, a hood is arranged at the top end of a vertical section of the exhaust funnel, and a negative pressure deodorization system fan is arranged on the exhaust funnel; and a jet mixing device for sucking ozone or deodorization drugs into the air pipe is connected in series on the air pipe between the odor collecting port and the inlet of the deodorization reactor or between the deodorization reactor and the negative pressure deodorization system fan. According to the invention, the air duct of the deodorization system is used as a space for deodorization reaction, the oxidative decomposition of odor is realized in the air conveyi
