Description

Facility for complex odor removal

The present invention relates to a complex odor removal facility, and more particularly, to a complex odor removal facility capable of effectively removing various and complex odors discharged from the odor generation facility.

In general, odors are generated from natural sources such as protein decomposition by microorganisms or the inherent odor of the substance itself, and from man-made sources such as various types of business sites. Among these, artificial sources of odors are sewage treatment plants, wastewater treatment plants, and manure. There are treatment plants, livestock manure treatment plants, food waste treatment plants, livestock facilities, landfills, incineration facilities, etc. In addition, they are generated in mobile pollutants such as cars and trucks, construction sites, garbage collection sites, and private houses.

On the other hand, looking at the main odor substances by source of odor, hydrogen sulfide and methyl mercaptan are mainly generated in livestock facilities, manure treatment plants, livestock manure treatment plants, and sewage treatment plants, and organic materials used in paint manufacturing, painting facilities, printing and ink manufacturing facilities. Hydrocarbons such as benzene, toluene, styrene, and xylene, and aldehydes and ester-based substances are mainly generated by the solvent. In addition, chlorine and hydrogen chloride are mainly emitted from fertilizer manufacturing facilities and incineration facilities, amines from foodstuff manufacturing facilities, and trichloroethylene and tetrachloroethylene from dry cleaning and laundry facilities. Organic acids, aldehydes, and sulfur compounds are mainly generated.

However, the conventional odor removal device is limited to removing some specific odor-causing substances from the odor-generating source, and in particular, for various and complex odor-causing substances discharged from food waste, etc., it is not possible to effectively remove odors in response to this. There was this.

In addition, the conventional odor removal device has a low reactivity, so that the input chemicals are excessively injected, and there is a problem in that the odor due to the chemicals is rather generated in the rear equipment.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

First, referring to FIGS. 1 and 2, the complex odor removal equipment 500 according to an embodiment of the present invention includes a neutralization module 100, a neutral module 200, a gas line 300, and a suction fan. Includes 400.

The neutralization module 100 dissolves and removes some of the odor-causing substances of the odor gas flowing from the odor generating facility 10 in water, and includes an acid neutralization module 1100 and an alkali neutralization module 1200. .

The acid neutralization module 1100 neutralizes acidic odor-causing substances such as hydrogen sulfide among the odor gases, and neutralizes acidic water in the storage space by dissolving the acidic odor-causing substances. Put in and remove.

The alkali neutralization module 1200 neutralizes alkaline odor-causing substances such as ammonia and trilmethylamine among the odor gases, and neutralizes water in the storage space having alkaline odor by dissolving the alkaline odor-causing substances. It plays a role of removing by injecting acidic substances from the outside.

Meanwhile, the neutralization module 100 connects the acid neutralization module 1100 and the alkali neutralization module 1200 in series in response to the odor gas so that the odor gas is converted to the acid neutralization module 1100 and the alkali neutralization module. While passing through the module 1200 in sequence, the odor-causing material is removed.

Preferably, the neutralization module 100 is preferably connected in series sequentially in the order of the acid neutralization module 1100 and the alkali neutralization module 200. This is because most of the odor gas has a high content in the order of alkali odor, acid odor, and neutral odor, which have alkali properties as odor-causing substances, but this is a preferred embodiment, depending on the odor-causing substance and the type of odor gas. It goes without saying that the order of arrangement of the processing units can be changed differently.

The neutral module 200 dissolves and removes the rest of the odor-causing substances of the odor gas flowing from the neutralization module 100 by dissolving in the water, and the oxidation neutral module 2100 and the reducing neutral module 2200 Includes.

The oxidation neutralization module 2100 serves to neutralize the odor gas by introducing an oxidizing agent from the outside so as to oxidize and decompose water in which odor-causing substances such as acetaldehyde, methyl sulfide, dimethyl disulfide, and methyl mercapic acid are dissolved.

Here, the oxidation neutralization module 2100 is often capable of removing odorous substances that are difficult to remove with water or neutralizing agents with an oxidizing agent. However, odorless substances are odorless due to oxidation reactions between oxygen, chlorine and odor-causing substances contained in the treatment liquid. Becomes, and is fixed in the treatment drug. Here, the oxidizing agent can cause a strong oxidizing effect on HClO, and deodorization by sodium hypochlorite having excellent handling and economical efficiency is preferable, but this is a preferred embodiment. In addition, sulfides such as hydrogen sulfide, methyl mercaptan, methyl sulfide, methyl disulfide, etc. Of course, if it is a component capable of achieving the above object, such as ammonia or trimethylamine, it can be applied in various ways.

The reducing neutral module 2200 serves to improve the deodorizing effect of the malodorous gas by removing substances that cause odors that are not properly removed from the neutralization module 100 and the oxidation neutral module 2100 using a reducing agent. do. That is, the reduction neutralization module 2200 reduces the neutralization module 100 and the oxidation neutralization module 2100 by introducing a reducing agent into water in which a odor-causing substance that is not properly removed by the neutralizing or oxidizing agent is dissolved. By doing so, it removes substances that cause odor.

In this way, the reduction neutral module 2200 not only reduces and removes the odor-causing substance, but also serves to remove odors caused by excessive injection of the oxidizing agent introduced from the oxidation neutral module 2100. That is, the reduction neutralization module 2200 serves to remove odors due to ClO gas generated from the oxidizing agent excessively introduced in the neutralization module 100 and the oxidation neutralization module 2100 described above. Since the concentration of the odor that is introduced is not constant, it is difficult to add a substantially accurate amount of the oxidizing agent, so that an excessive amount of the oxidizing agent is inevitably introduced, resulting in the presence of weak gaseous substances in the oxidation reaction, resulting in odor. Accordingly, the reduction neutral module 2200 reduces and removes the odor-causing material generated by the oxidizing agent.

Here, the neutral module 200 connects the oxidizing neutral module 2100 and the reducing neutral module 2200 in series in response to the odor gas so that the substance causing the odor is removed, and the oxidation neutral module 2100 ) And the reduction neutral module 2200 are sequentially connected in series in that order.

Here, the operation of the acid neutralization module 1100 is stopped so that the odor-causing material of the odor gas cannot be dissolved in water, but the odor gas is a blocking plate 1171 and an eliminator 1172 to be described later. Since it passes through the configuration of the odor gas, it can play a role of micronizing the odor gas and collecting moisture.

Referring to FIG. 8, the body 1110c is a structure consisting of one sub-space 1113 and a pair of main spaces 1114 communicated to both sides of the sub-space 1113, and the sub-space 1114 at the center side When the odor gas flows into the space 1113, the odor gas flows out to the main spaces 1114 on both sides, and the odor gas discharged from the pair of main spaces 1114 is collected and flowed again. Here, the same reference numerals denote the same configuration.

As described above, the body has various configurations of the venturi module 1150, the water tank 1161, the water flow plate 1162, and the odor removal means installed therein in response to the odor gas. Of course, it can be selected and installed, and its structure can also be designed in various ways.

The present invention has been described with reference to the embodiments shown in the drawings, but these are merely exemplary, and those of ordinary skill in the art will appreciate that various modifications and equivalent other embodiments are possible therefrom. Therefore, the true technical protection scope of the present invention should be determined by the technical spirit of the appended claims.
