Good deodorization effect can be exerted by sufficient contact, and the gas deodorized in the tank is gradually raised by the suction of the exhaust fan provided in the filter and passes through the bag filter. However, even during this passage, it comes into contact with the deodorant layer attached to the surface of the bag filter, so that the repetition of such contact can exhibit a more excellent deodorizing effect. Since the deodorant can be peeled off and replaced with another deodorant, and the peeled-off deodorant can be re-contacted with the odor gas in the tank immediately below, the deodorization of the odor gas can be more effectively performed. , Efficient It makes it possible to perform.

According to the means described in the above (2), a number of air supply pipes are alternately installed at different positions so as not to interfere with each other. Since the odorous gas is blown out into the tank from a number of drilled air holes, the odorous gas must be diffused into the tank and evenly supplied to make an average contact with the deodorant in the tank. In addition, the odor gas can be brought into contact with the deodorant accumulated on the lower side of the tank, so that a more excellent deodorizing effect can be exhibited.

According to the means described in the above (3), since the pressurized odor gas is once sent to the supply chamber and distributed and supplied from the supply chamber to each supply pipe, the odor gas is supplied to each supply pipe. As a result, the odorous gas can be uniformly jetted into the tank and brought into contact with the deodorant, so that the deodorizing effect of the deodorant can be further enhanced.

According to the means described in the above (4), the deodorant which flows in the tank to fulfill the mission of deodorization, and which is depleted and sinks downward, accumulates in the inner bottom of the hopper-shaped tank. The accumulated deodorant is discharged by a screw conveyor provided at the inner bottom to the discharge port and can be replaced with a new one, so that the deodorizing function in the tank is always maintained in an excellent state. enable.

According to the means described in the above (5), the pressurizing operation of one pressurizing fan is used to pressurize the supply of the odor gas to the tank and to supply the deodorant supplied to the inlet. Therefore, the configuration of the entire deodorizing device can be greatly simplified and rationalized.

As described above, the above-mentioned technical problems can be solved by the above-mentioned means, and the problems of the conventional technology can be solved.
