DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a deodorizing device installed in various factories so as to uniformly deodorize the entire plant.

[0002]

2. Description of the Related Art Conventionally, in a printing plant, a rubber product processing plant, etc., one package type deodorizing device a is installed on a building wall x to deodorize harmful, odorous gas and polluted air diffused to a low concentration. However, the polluted air was sucked through the suction port b below the deodorizing device a, and the purified air deodorized by the deodorizing rotor c of the internal mechanism was returned to the inside of the factory or the building through the exhaust port d above the deodorizing device a. .

As a result, the polluted air in the vicinity of the deodorizing device a is purified, but the suction amount of the polluted air away from the deodorizing device a, for example, in the oblique directions y, y1 and the building-facing wall surface y2 side is small, and therefore the building interior is reduced. This has the disadvantage that imbalance occurs in the degree of purification and concentration of the polluted air, and the distribution of the residual polluted air and the residual concentration of the odor component become non-uniform.

Further, if a large number of intake ducts are arranged in the factory building in order to deal with the non-uniform purification in the above-mentioned construction, the equipment cost will rise, and at the time of inducing the suction of polluted air by the intake duct, the inside of the intake duct will be increased. There is a drawback in that intake resistance occurs during the passage, and the intake fan and its operating energy must be increased.

Also, a deodorizing rotor c built in a deodorizing device a
For example, while making the deodorizing element a honeycomb shape,
Since it is formed in a spiral shape and concentric shape, there is a disadvantage that the cost of manufacturing and processing the deodorizing rotor c as the deodorizing filter is high.

[0006]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a deodorizing apparatus capable of performing uniform deodorizing in a factory building with a low-cost apparatus without using a large number of intake ducts.

[0007]

SUMMARY OF THE INVENTION The present invention is based on the above-mentioned prior art, and it is difficult to uniformly deodorize the entire factory building or requires a large number of expensive intake ducts. In view of the problem of high cost,
