Description

A device for removing odor using a chemical solution and ozone water{apparatus for removing odor}

The present invention relates to an odor removal device using a chemical solution and ozone water, and more specifically, a scrubber is installed at the front and rear ends, respectively, and the odor is firstly removed by the chemical solution in the scrubber at the front end, and the odor by ozone water is used in the scrubber at the rear end. It relates to a malodor removal device capable of effectively reducing malodorous substances by removing the secondary.

Generally speaking, odor refers to a odor that stimulates a person's nervous system and causes mental and physical damage. These odor-causing substances are very diverse depending on the source, and sewage treatment plants, incineration plants, food waste treatment facilities, waste landfills, oil refineries, chemical plants, manure and livestock wastewater treatment plants are considered to be major sources of odor in cities.

Since the odor generated from the odor generating facility is caused by decaying substances or various volatile organic compounds, it not only causes discomfort, but is also harmful to the human body, and there are many problems ranging from a decrease in efficiency or an increase in safety accidents due to a decrease in concentration. do.

As such odor components, ammonia, methyl mercaptan, hydrogen sulfide, methyl sulfide, methyl disulfide, trimethylamine, acetaldehyde, and styrene are regulated and regulated as legally regulated substances.

Malodorous substances can be classified into basic, acidic and neutral systems depending on the pH. For example, ammonia and trimethylamine belong to the basic system, hydrogen sulfide, methyl mercaptan, propionic acid, normal butyric acid, isovaleric acid, etc. belong to the acidic system, and methyl sulfide, methyl disulfide, acetaldehyde, etc. belong to the neutral system. Belongs.

Conventional methods for removing such malodorous substances are largely classified into physical, chemical and biological treatment methods, and currently mainly used methods include combustion methods, washing methods, oxidation methods, adsorption methods, and microbial treatment methods.

Among them, the combustion method is effective in removing almost all flammable odors, but the fuel cost or maintenance cost required for catalyst replacement is expensive, and if the operation management is neglected, nitrogen oxide is generated and there is a risk of explosion. In addition, the oxidation method utilizes the strong oxidation of ozone to oxidize and remove odor components.It consumes little power and is easy to maintain, so it is relatively efficient in removing large-capacity gases, but ozone alone has a small scope of application and insufficient performance. There are drawbacks.

The adsorption method is a method of removing odors using activated carbon.When various odor substances accumulate in the pores of activated carbon and are adsorbed in a saturated state, there is no more deodorizing effect and the odor begins to flow out. When the concentration of the target material is high, there is a disadvantage in that the concentration is reduced by performing pretreatment steps such as washing, absorption, cooling, and condensation, and then activated carbon adsorption is performed.

In addition, the microbial treatment method is a method of decomposing odor substances adsorbed using microorganisms when odor passes through wood debris or soil. If the growth conditions of microorganisms are properly established, the ability to remove odors is excellent and secondary pollutants are generated. On the other hand, it takes up a lot of land and takes a lot of time.

Republic of Korea Patent Registration No. 10-1454794 discloses a deodorizing device that improves the contact efficiency of the chemical liquid and odor gas.

The deodorizing device is a cleaning method, and is a method of deodorizing the odor gas by washing it with water, an acid, or an aqueous alkali solution. This method has the advantage of relatively simple equipment and low operating cost, but has a problem in that the range of application of odor substances is narrow and the effect of odor removal is low.

Korean Patent Registration No. 10-2017252 discloses an odor removal device.

The odor removal device has a multi-stage interior of the scrubber and uses two or more kinds of chemicals to enhance the odor removal effect, but there is a limit to enhancing the odor removal effect with only a chemical solution.
