Description

Removing Method of Bad Smell and Dust Using Bubble and Air Cleaning Apparatus Thereof}

The present invention relates to a deodorization and dust removal method using a bubble water film, and an air purifying apparatus using the same, and a method and apparatus for efficiently removing various odors, steam particles and dust generated in various industrial sites and underground spaces It is about.

Currently, there are about 10,000 kinds of odorous substances that generate unique odors among the compounds present on the earth. These odors are caused by a combination of chemical substances of various components. Inhalation of odors contained in the air is not only harmful to health but also adversely affects mentally.

Odor is not easy to define uniformly due to various kinds of odor causing substances, the complex action between odor causing substances and the difference in personal smell. In other words, when odorous substances are mixed with each other, the odor intensity may be increased, but sometimes the odor may be neutralized, and the extent of the damage may vary depending on the mental and physical state of the person exposed to the odor and the conditions of the environment.

In addition, when accustomed to one kind of odor can be detected only when a change in the intensity of the odor occurs, even if the odor is actually exposed to the odor does not occur.

When a person is exposed to such a bad smell for a long time, it can lead to loss of appetite, vomiting, insomnia, allergic symptoms, psychoneuropathy, disturbance of emotional life, deterioration of work efficiency, and serious effects at high concentrations. .

However, research on odor pollution has been poorly performed compared to studies on air pollution. Despite various sources of odor and pollutants, the current status of each industry is not known.

One reason is that there is no established quantitative test method for malodorous substances causing malodors. In addition, the odor contamination items are not maintained for each industry, and the odor substance is comprehensively managed. In the future, mitigation techniques and management measures should be taken separately for each source of odor.

According to the current odor prevention law, "odor is a smell of hydrogen sulfide, mercaptans, amines, and other irritating gaseous substances that irritate the human sense of smell and cause disgust." In addition, "designated malodorous substance" means a substance causing odor, and is designated by the Ministry of Environment, and "odor emission facility" means an odor causing facility, machine, apparatus, etc. It is prescribed by Ordinance of the Environment in consultation with the Chairman.

 There are many kinds of odorous substances on earth and their odor characteristics and strengths are different. Representative odorous substances include ammonia, methyl mercaptan, hydrogen sulfide and dimethyl sulfide. And eight of methyl disulfide, trimethylamine, acetaldehyde, and styrene.

Among the odorous substances, ammonia is an irritating odor such as urine, methyl mercaptan is an irritating sulfur smell, hydrogen sulfide is a rotten egg smell, methyl sulfide and methyl disulfide are corrupt cabbage smell, and trimetalamine is a corrupt fish smell, acetaldehyde Sour and burning smell, styrene, is causing the smell of gasoline.

In addition, odor-causing substances are broadly divided into volatile organic compounds (VOCs) such as benzene, toluene, phenol, and mercaptans, and volatile inorganic compounds (VICs: Volatile Inorganic Compounds) such as ammonia, chlorine, and hydrogen sulfide. You can also classify.

In addition, odorous substances may be classified as follows according to the composition of the compound.

First, there are nitrogen compounds that occur at low concentrations in livestock-related manure, sewage and wastewater treatment plants, which includes ammonia. Sulfur compounds known as representative odor-causing substances include hydrogen sulfide, methyl sulfide, methyl disulfide, methyl mercaptan and the like.

In addition, lower fatty acids generated in a maintenance plant, manure, sewage and wastewater treatment plants include acetic acid, propionic acid and the like. Carbonyl compounds produced during incomplete combustion of fuels, food chemical and petrochemical products include formaldehyde, acetaldehyde, butylaldehyde and acetone.

In addition, there are esters that are used as solvents of organic materials or occur in acetic acid manufacturing plants and acrylic manufacturing plants, and phenols and cresols generated in chemical plants, cresol manufacturing plants, and electromagnetic plate manufacturing plants.

Alcohols that dissolve well in water and cause hallucinations and anesthesia include hydrocarbons, benzene, toluene and xylene, and chlorine compounds that cause strong skin irritation and abnormalities of the central nervous system.

According to the current Air Pollution Conservation Act, discharge facilities that are likely to cause odors are regulated as odor management centers and other facilities are regulated as living odor regulation facilities.

Direct odor, air dilution, and chemical analysis (instrument analysis) are widely used as a method for measuring such odors.

First, the direct sensory method is a method in which a measurer detects odor in the field. In other words, odor odor not detect odor at all 0, odor detection detects some odor 1, normal odor 2, strong odor 3, very strong odor 4, endurance Difficult odor is divided into 5 odors, and administrative measures are imposed when odors detected by 3 or more persons are 3 or more. It is a simple method, but it is a highly subjective measurement method.

The air dilution sensory method is a method of obtaining a dilution rate when an air sample collected in a measurement target area is carried out to a test room and then increasing the dilution rate with odorless air in a scentless manner. It can be divided into The dilution ratio should be below a certain value by dividing the workplace in the industrial area with the workplace in the other area, and dividing the odor outlet and the site boundary. This method can also have the subjectivity of a particular person.

On the other hand, the chemical analysis measurement method is a measurement method capable of qualitative analysis and quantitative analysis and is also called an instrument analysis method. It is possible to satisfy the emission allowance standard by dividing the workplace in the industrial area and the workplace in the other area to be below a certain concentration for each odorous substance. There are GC method and UV method. In general, GC method is widely used.

In this way, odors are regulated by relevant laws, and each workplace uses various methods to remove odors and harmful gases (hereinafter referred to as 'odors').

So-called hydrophilic components such as ammonia, lower amines, ketones, aldehydes, lower organic acids and phenols are absorbed by water.

For hydrophobic components having a relatively high molecular weight and not being hydrophilic, activated carbon is mainly used as the adsorbent. Activated carbon is widely used for the removal of low concentration mixed odors.

Recently, a method of mixing and molding an adsorbent, a chemical, a strong oxidant, and the like to dryly adsorb a malodorous gas and performing an oxidative decomposition treatment by a chemical reaction is also used.

The flammable odor of hydrocarbons is highly effective by using direct combustion or catalytic combustion, and the effect is increased by oxidizing and absorbing ozone to remove odors of sulfur compounds.

In low concentrations of odors, the odor can be offset by spraying fragrance substances that are stronger and harmless than odor gases or by mixing other odorants.

In addition, there are soil deodorization using microorganisms of soil, and catalytic decomposition to decompose using liquid catalyst.

Hereinafter, the characteristics of the method generally used among the various odor removal methods described above will be described.

First, the combustion method may be classified into a direct combustion method and a catalytic combustion method.

The direct combustion method can be applied to all combustible odors and can exhibit a high performance odor removal effect if the conditions are set properly. However, negligence in management leads to incomplete combustion, which generates nitrogen compounds harmful to the human body, and has a disadvantage of high maintenance costs.

The catalytic combustion method exhibits a high-performance odor removal effect in a combustible gas containing no catalyst poison, and has the advantage of long life of the catalyst without fear of secondary pollution. However, there is a problem that the catalyst is expensive and the performance of the catalyst decreases with time.

The adsorption method is the most common method of adsorbing malodor using activated carbon, but there is a problem that the deodorizing power decreases depending on the adsorbent and is unsuitable for removing high concentration of malodor.

The microbial method has the advantage of removing almost all odors, having an excellent ability to remove odors and not generating secondary pollutants, but has a disadvantage of requiring a very large installation area and keeping warm.

The washing method can be broadly divided into a washing method and a chemical cleaning method.

Water washing method is mainly used to remove urban sewage manure, odor associated with food processing, has the advantage of relatively simple equipment and low operating cost. However, there is a problem in that the application range is narrow and wastewater is generated.

The chemical cleaning method is used to remove simple odors other than hydrocarbons, and has a wide range of applications and high performances compared to the flushing method, but it is difficult to process complex odors, requires measures to prevent corrosion by chemicals, and generates wastewater. have.

The chemical oxidative decomposition method is used to remove simple odors other than hydrocarbons, and it is inexpensive to operate and is suitable for removing a large amount of gas, and can be applied to after-installation of other facilities.
