Description

Complex impinge jet 3-stage chemical cleaning tower for efficient odor treatment {Wet Scrubber Tower}

The present invention relates to a complex impinge jet three-stage chemical cleaning tower capable of efficient odor treatment.

In addition, a large amount of gases including odors and volatile organic compounds (VOCs) generated during the process of wastewater treatment plants and various industrial facilities are emitted, causing air pollution.

In particular, the sewage treatment plant is adjacent to the residential facility, and there are many complaints due to odor. Volatile organic compounds cause photochemical reactions in the atmosphere to generate photochemical oxidizing substances such as ozone, causing photochemical smog.

In addition, volatile organic compounds are not only air pollution, but also carcinogenic substances, and as a cause of global warming, various countries have implemented various policies to reduce emissions.

Accordingly, various devices have been developed to remove the contaminated gas, and among them, a chemical cleaning tower, also called a scrubber, is a device for collecting solid, gaseous or liquid particles suspended in a gas using acidic and basic chemicals. .

For example, in Korean Patent Publication No. 10-2011-0043134, a gas scrubber as shown in FIG. 1 is known.

Conventional gas scrubbers are disposed in the inner space of the case 100 and the case 100 having an inlet 111 and an outlet 115 formed at positions spaced apart from each other for the entry and exit of exhaust gas, and the adsorbent is filled. It includes one or more adsorption parts 135 and one or more moisture absorption buffer parts 145 in which a water absorbent is filled as being disposed in the inner space of the case 100.

In addition, to minimize the influence on the flow rate of the exhaust gas between the adsorption portion 135 and the moisture absorption buffer portion 145, a mesh-shaped protection net 125 is included.

At this time, there is a problem in that a separate chamber for storing the water absorbent flows to the inflow space part 112 through the protection net and stores it.

In addition, due to the moisture absorption buffer unit 145 composed of multiple stages, the water absorbent is mixed while flowing to the lower side, and thus there is a limitation that only one type of water absorbent can be used.

Accordingly, since a water absorbent is used to clean exhaust gases containing various volatile organic compounds, there is a problem that substances having strong basicity or strong acidity cannot be removed at the same time.
