Description

Ecological circulation type odor reduction system {ECOLOGICAL CIRCULATION TYPE ODOR REDUCTION SYSTEM}

The present invention relates to an ecological circulation type odor reduction system, and more particularly, to an ecological circulation type odor reduction system including a scrubber in which biological treatment and physical treatment are combined using an aeration tank including complex fermentation microorganisms and a microbubble generator. it's about

Scrubber refers to wet processing of pollutants such as fume, mist, dust, highly soluble harmful gases, and chemicals. The scrubber is also called a cleaning dust collector or a wet dust collector, and is mainly used for collecting soluble gas. The scrubber is also a device that cleans the dust gas with liquid droplets, liquid films, bubbles, etc., adheres to the particles, promotes aggregation between particles, and directly separates the particles from the flow of gas.

In addition, the scrubber is used in various ways not only for gas absorption but also for increasing oil, steaming, and removing dust and liquid droplets. The scrubber is configured in various ways, and a method of treating contaminants by direct contact with liquid is generally used. Here, water is mainly used as the liquid.

On the other hand, gaseous pollutants include odorous substances mainly containing hydrogen sulfide and nitrogen oxides. Here, the odorous substances can cause physical pain such as aversion to headaches in severe cases, and nitrogen oxides increase the amount of ozone in the atmosphere by photochemical decomposition and create smog along with hydrocarbons, causing damage to humans, animals and plants. However, since it reacts with OH radicals in the air to form nitric acid, it can cause environmental destruction such as acid rain.

Accordingly, Korean Patent Registration No. 10-2116253 discloses a scrubber device capable of simultaneously removing odor and nitrogen oxides. Referring to FIG. 1, the scrubber device includes a liquid tank 1, a gas-liquid contact part 2, a gas inlet part 3, a liquid supply part 4, and an exhaust part 5, but a chemical supply part 6 As further included, it is disclosed that the pH concentration of the liquid tank 1 is kept constant to remove the odor by contacting the alkaline liquid with the gas.

As such, currently well-known scrubbers for removing odors and collecting dust generally rely on chemical treatment of liquid sprayed by nozzles. However, in the case of using a large amount of chemicals for chemical treatment, there is a problem of low economic feasibility due to increased purchase costs and maintenance costs due to clogged nozzles or corrosion of the device. In addition, it may lead to the disadvantage of frequently replacing the cleaning circulation water and the problem of wastewater treatment by chemicals.
