Description

TECHNICAL FIELD [0001] The present invention relates to a disinfection apparatus for disinfection and disinfection of a sweeper using ultrafine chlorine dioxide,

The present invention relates to a deodorizing and disinfecting device for a cleaner, and more particularly, to a deodorizing and disinfecting device for a deodorizer of a sweeper, in which ultrafine chlorine dioxide is sprayed to remove odors or bacteria when a debris is loaded on a sweeper will be.

In general, the development of various packaging containers and the popularization of instant foods have led to flooding of household garbage at home, and a lot of manpower has been required to collect and process such household garbage. In recent years, garbage collection vehicles It has been developed so that garbage can be collected somewhat conveniently.

Conventional sweepers are constructed such that a garbage loading box is mounted on a vehicle, garbage is poured from the rear of the loading box to a loader, and the garbage is conveyed to a storage bin after being pressurized by a pressurizer. However, when collecting the garbage by such a sweeping car, the garbage collecting worker suffered a considerable trouble due to the odor generated from various household garbage, and there was a problem that the general people around the sweeping car had considerable hygiene discomfort.

The odor is a representative sensory pollution through the sense of smell that is sensed by the human senses, causing discomfort and disgust at a very low concentration, causing distrust of environmental policy, caused by a mixture of compounds rather than a single substance, There is a combination of odor intensity through additive, offset, synergistic action, local, instantaneous occurrence and disappearance.

It should be removed because it induces mental and physiochemical stresses on humans and causes subjective reactions of the body such as nausea, headache, loss of appetite, dyspnea and allergic symptoms. To date, about 2 million compounds are known to exist on the earth, and 200,000 to 400,000 compounds are reported to cause odors. The substance causing the odor is very diverse such as organic acids, alcohols, amines, aldehydes, esters, and hydrogen sulfide, and there is a difference depending on the kind of the substance.

Air pollutants are generated continuously and continuously through discharge ports such as chimneys, and they affect hundreds of kilometers from the source. On the other hand, odor is generated instantaneously from surface contamination in a wide range of places, It has characteristics that affect from source to several kilometers. There have been many technological developments and patent registration for eliminating these odors, and it has been difficult to commercialize them until now. It has been difficult to commercialize the odor removing material which quickly removes odor, a nozzle for reacting with odor gas in the fastest and efficient manner, This is because technology has been limited. As a result of field experiments with various odor elimination agents, it was found that chlorine dioxide is the most effective to remove odor.

Odor control by chlorine dioxide (ClO₂) and disinfection method has been widely used in various advanced countries since it was used as a disinfectant in the water purification plant since the 1950s. The US Environmental Protection Agency (EPA) is licensed for use in drinking water, factory drainage and environmental cleanup (21164-3). The US Food and Drug Administration (FDA) licensed it for use as a food additive, medical device and disinfectant (CAS Reg No. 10049- 04-4). In addition, the World Health Organization (WHO) has classified A-1 as the safest grade of food additive, and ADI A-1 as the UN Food Additives Task Force. In Korea, the Ministry of Environment, the Ministry of Agriculture and Forestry, and the Food and Drug Administration have recognized food additives, food disinfectants, foot-and-mouth disease, and highly pathogenic avian influenza.

Chlorine dioxide (ClO₂) is used in water purification process with its disinfection ability improved about 2.5 times than chlorine, and recently it is widely used in odor treatment process. In this background, the generation rate of THMs (trihalomethanes) and HAAs, which are disinfection byproducts and carcinogens, is low, and they are economically replaced by chlorine as an oxidant instead of UV and ozone processes. In addition, chlorine dioxide (ClO₂) is completely decomposed by ultraviolet light, and is left in the atmosphere due to its optical degradation, completely destroying the possibility of unexpected damage. In addition, chlorine dioxide (ClO2) is a chlorine compound with +4 transverse neutrality in oxidation state and shows high solubility even in cold water. If it is more than 11 ℃, the solubility is recorded about 10 times of chlorine. Furthermore, chlorine dioxide (ClO2) is present in the form of dissolved gas in solution as it decomposes 7 to 10 million times slower than hydrolysis of chlorine.

Chlorine dioxide (ClO₂) removes almost all odors, and the principle of elimination of representative odors is as follows.

2NHS ₃ + 2ClO ₂ + H ₂ O NH ₄ ClO 2 + NHClO ₃

Hydrogen sulfide

On the other hand, ultra-low volume means "to use the least amount of water", which is environmentally friendly by minimizing the side effects of the drug by minimizing the chemicals used.

These ultra-fine particle (ULV) drug particles are similar in size to odor molecules (about 1 to 5 microns) and do not fall on the floor but stay in the air. The gas odor molecules and liquid form drug molecules are contacted at almost the same size, The effect of the drug can be maximized.

The technology related to the present invention discloses a cleaner of Patent Document 1, a malodor removing device of a cleaner of Patent Document 2, and the like. However, there is a fear that the danger of the sterilization and pesticide used may be adversely affecting the health of the operator However, there is a problem that freezing occurs due to the stagnation of the medicine in the winter season and the residual in the nozzle, so that the normal operation can not be performed.
