Description

[0001] The present invention relates to a stench reducing apparatus,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a malodor cleaning type malodor reduction apparatus applied to various industrial facilities and environmental facilities where malodorous substances are discharged such as sewage treatment facilities and waste recycling facilities, Thereby reducing the odor, and at the same time, the recycle of the chemical liquid used in the scrubber is repeatedly recycled, so that the process cost and the maintenance cost can be greatly reduced. will be.

For example, various industrial facilities and environmental infrastructure facilities such as sewage disposal facilities and waste recycling facilities not only cause civil complaints related to odor but also discharge various pollutants into the atmosphere. . Accordingly, in the case of various industrial facilities and environmental facilities where odorous substances are discharged, various techniques for reducing odor are applied.

 In order to effectively manage the spread of odors emitted from various industrial facilities and environmental facilities that cause odor, such as weather conditions and topographical factors, Regulations are strengthened.

In various industrial facilities and environmental basic facilities where odorous substances are discharged, methods of reducing odor can be divided into physicochemical methods and biological methods according to the odor characteristics and the treating capacity of the odorous substances.

In particular, in the case of a facility where odorous substances, which are not highly concentrated in odor and easily oxidized, are discharged at a high flow rate, a chemical liquid cleaning method using a scrubber is used most often. In the case of a facility where acid gases such as hydrogen sulfide (H ₂ S) are discharged, a caustic soda (NaOH) solution is used to clean the chemical solution using a scrubber. In the case of a facility where basic gas such as ammonia (NH ₃ ) An aqueous solution of sulfuric acid (H ₂ SO ₄ ) is used for cleaning the chemical solution. However, high concentration of caustic soda aqueous solution and sulfuric acid aqueous solution require professional manpower in handling and there is a risk of safety accident when leaking.

Recently, an aqueous solution of HOCl (hypochlorite) having strong oxidizing power has been used to effectively oxidize and decompose acids, bases and volatile organic matters such as hydrogen sulfide and ammonia.

Korean Patent Registration No. 10-0961721 (published on Jun. 10, 2010) discloses an example of a scrubber containing a malodor cleaning type malodor reducing apparatus using a hypochlorous acid aqueous solution as a chemical liquid, A first purifying tank in which a filler and a first purifying agent are accommodated; a second purifying agent for supplying purified air through the first purifying tank to the second purifying tank; and a second purifying agent supplied through a transfer pipe and a transfer pump A second purifier which is equipped with a spray nozzle for spraying onto the upper portion of the second filler; a demister filter for removing moisture from the second purified air; Wherein the first purification tank comprises a first purification agent storage chamber and a second purification agent storage chamber for storing the first purification agent and the second purification agent, respectively, Wherein the second purification tank is mounted on an upper portion of the first purification tank and the bottom surface is inclined and communicated with the second purification agent storage chamber so as to collect the second purification agent, Wherein the first cleaning agent is filled at a predetermined level in the first cleaning agent storage chamber, and the first cleaning agent storage chamber is disposed at a lower side of the first cleaning agent storage chamber, The odor gas injection pipe extending inwardly from the odor gas injection pipe and spraying the contaminated air through the plurality of discharge holes formed in the surface and spraying the contaminated air in the primary purifying agent, And a first water level sensing unit for maintaining the first water level sensor at a predetermined water level is mounted on one side of the upper side, Wherein the perforated pipe is seated on the perforated plate so as to increase the contact time with the primary purifying agent and increase the deodorization efficiency while prolonging the retention time while refining bubbles of the contaminated air injected from the odorous gas injection pipe, The second cleaning agent storage chamber includes a second water level sensor for maintaining the second cleaning agent at a predetermined water level, and a second water level sensor for maintaining the second water level sensor at a predetermined level, And an overflow preventing pipe for preventing the tea purifying agent from flowing into the interlocking pipe. The aeration scrubber using two aqueous solutions is disclosed.

However, in the case of an aqueous solution of sodium hypochlorite, which is used as a chemical solution, it has an effect of effectively reducing odor generation as an oxidizing agent having a strong oxidizing power, but it requires a high processing cost depending on the load of the odor material. In addition, since the malodor cleaning type malodor reduction apparatus using the aqueous solution of hypochlorous acid as the chemical liquid reduces the malodor reduction efficiency by reducing the chlorine ion and the various pollutants reduced in the chemical solution when the chemical liquid is not operated for a long time, It is necessary to replace the wastewater with the wastewater by a consigning company, and thus a considerable maintenance and management cost is required.
