The present invention relates to a disinfectant dispensing device that sprays a liquid disinfectant (sterilizer or insecticide) in the air or sprays a target object to kill various pests and various harmful bacteria (bacteria, viruses, anthrax, mold, etc.), in particular, By disinfecting liquid disinfectant at low temperature by ultrasonication at low temperature, vaporizing the disinfectant in the form of very fine particles at room temperature, it is possible to disinfect a wide range even with a small amount of disinfectant. The present invention relates to a vaporization and disinfection apparatus for disinfecting drugs using ultrasonic waves, which can be obtained by spraying disinfecting drugs and digging in every corner.

Conventional insecticides, methods and apparatuses for spraying disinfectants, such as fungicides, can be largely three examples.

First, we can see the nozzle injection method and apparatus for diluting the disinfectant in water and spraying it through the spray nozzle.

Secondly, there is a fume (smoke) disinfection method and apparatus which burns combustible materials such as diesel oil or thinner and injects disinfectant in a mist state along with combustion gas.

Thirdly, it can be seen that a bromine compound such as methyl bromide is gasified and used by fumigation.

In this way, the nozzle spray disinfection method is mainly used for sterilizing insects such as crops or roadside trees rather than air disinfection, and is sprayed in a high-speed spray or mist through a fine nozzle by pumping a liquid disinfectant.

However, since the liquid disinfectant sprayed through the nozzle is sprayed in the form of small droplets, the disinfectant is not sprayed every corner, and thus a large amount of disinfectant is consumed. In addition, when sprayed in the form of water droplets is not immediately evaporated and is absorbed into the soil, it also removes earthworms and useful bacteria, which are useful organisms in the soil, and causes secondary closures that acidify the soil. It will provide a cause for worsening the water quality.

In addition, a smoke screen that burns combustible materials such as diesel oil or thinner and sprays disinfectant with a combustion gas in a mist (smoke) is mainly used to exterminate pests such as mosquitoes and flies in the air.

That is, when combustibles are combusted to spray disinfectant, and when disinfectant is sprayed together with combustion gas, the pollutants are discharged by oxidizing pollutants generated during the combustion of combustibles, and toxic dioxins and futan based substances. Are discharged together to cause pollution,

Disinfectant drugs are weak due to the heat of combustion, and the actual sterilization and insecticidal ability is very weak. Especially, when SO ₂ contained in the combustion gas is absorbed through the pores of the plant, chlorophyll decolorizes and destroys cellular tissues. Drying leaves or changing them to tan or brown will cause damage to the plants.

Methyl bromide, which is commonly used as a fumigation, is used as a pest control agent for stored foods. In addition, it can be seen that it is used for disinfecting cultural properties or quarantine cargo.

Methyl bromide, used by fumigation, comes into contact with flames during combustion, producing harmful gases such as embrittlement, oxy-brittle carbon, and carbon monoxide.They are very toxic, causing lung edema and walking problems when breathing. It causes skin damage such as burns, and is highly corrosive, so it is necessary to be very careful in handling because it corrodes bronze, aluminum, synthetic resin and rubber.

The present invention as described above, the conventional sterilization, insecticidal method or the device does not effectively spray disinfectant, but rather causes the use of soil pollution and excessive disinfectant, the present invention was developed to solve the environmental pollution caused by this In the present invention, the disinfectant may be sterilized in a small amount by disinfecting at room temperature (15-25 ° C.), that is, by spraying it at a low temperature and spraying it in a mist state, and the effect is excellent, and the environment It is to provide a device that does not cause damage, such as pollution or soil pollution.

The pre-registered patent corresponding to the present invention can be seen patent registration No. 10-332094 "Evaporation spray device of the disinfectant using ultrasonic wave" and Patent Registration No. 10-516114 "Evaporation spraying device of the disinfectant using ultrasonic wave". .

The pre-registered patent has been invented by the inventors and has been filed by the applicant, but the equipment can be suitably used for sterilization and insecticide in a large and large area, but it is relatively inconvenient to move, and thus it is inconvenient. The present invention has been devised in view of having it.

The present invention can be usefully used as a dispersing device for neutralizing or detoxifying agents, such as biochemical weapons sprayed at the time of chemical discharge, as well as disinfectant vaporization spraying of disinfectants and insecticides, and methyl bromide used for pest control and quarantine of stored foods. It was developed to be used as an alternative.

In the present invention, the disinfectant such as liquid insecticide, disinfectant, etc. is boiled at room temperature to be generated in a mist (smoke), so that the amount of the disinfectant is sprayed by using a conventional nozzle or a method of injecting a disinfectant by burning combustible materials. To achieve extremely high sterilization insecticide disinfection efficiency,

 The liquid disinfectant is boiled at low temperature with a pneumatic ultrasonic generator using compressed air or compressed gas to be vaporized and sprayed with fine water particles.

In particular, the present invention has a vaporization tank for vaporizing a liquid disinfectant, and installed inside the pneumatic ultrasonic generator by compressed air or compressed gas, vaporized by the vibration of the piezoelectric ultrasonic vibrator in the disinfectant that is vaporized by pneumatic It has a vacuum generating tank to increase the amount of vaporization and vaporize into fine particles by reducing the pressure in the vaporization tank, and to have a structure that mixes air into the disinfectant generated by evaporation of fine particles and sucked and sprayed through a blower. .

In addition, the high pressure gas tank (51-1) filled with nitrogen, oxygen or carbon dioxide at a high pressure in place of the air compressor in the above, it can be configured the present invention.

In the figure, reference numeral 30 denotes a flow level sensor.

Referring to the structure of the ultrasonic generator 16 by the compressed air or compressed gas used in the present invention as follows.

The pneumatic ultrasonic generator 16 which is immersed in the disinfectant 11 of the vaporization tank 12 has a plurality of pneumatic ultrasonic generators 16 connected to the compressed air distribution pipe 42 connected to the compressed air supply pipe 41, The pneumatic ultrasonic generator 16 has a cylindrical ultrasonic vibrator 43, the inner side of the diaphragm 44 having pores in the center facing each other, the outside of the ultrasonic vibrator 43, the extrusion on the split It is composed of a structure having a hole 45.

The present invention having such a structure will be described in more detail and at the same time as follows.

The disinfectant 11 is injected through the upper injection valve 21 into the vaporization tank 12, and the liquid disinfectant 11 is injected to lock the pneumatic ultrasonic generator 16.

Compressed air or high pressure compressed in the air compressor 51 or the high pressure gas tank 51-1 through the air supply pipe 41 to the pneumatic ultrasonic generator 16 immersed in the disinfectant 11 of the vaporization tank 12 as described above When the gas is supplied, ultrasonic waves are generated in the pneumatic ultrasonic generator 16 to vaporize the liquid disinfectant 11 at room temperature to vaporize into a mist state, and is introduced into the vibration generating tank 31 through the supply pipe 25. Then, it is sucked by the upper vacuum fan (vacuum pump) 33 and discharged to the discharge pipe 32 in the mist state to sterilize, disinfect, or kill the object to be disinfected.

Referring to the structure and the ultrasonic generation process of the pneumatic ultrasonic generator 16 by the compressed air or compressed gas used in the present invention.

Ultrasonic vibrator 43 in which 7-10 kg / m 2 compressed air or compressed gas generated from the air compressor 51 or the high pressure gas tank 51-1 is connected to the compressed air distribution pipe 42 through the air supply pipe 41. ) When the compressed air passes through the pores formed in the diaphragm 44 installed to face each other inside the ultrasonic vibrator 43, the diaphragm 44 facing each other generates a vibration waveform of 1,000 to 1,600 cycles. The generated vibration waveform passes through the split-shaped extrusion hole 45 formed outside the ultrasonic vibrator 43 and is 20-250 KHz. Ultrasonic waves are generated in the range and the ultrasonic waves generated in this way change the phase into fumes by vaporizing the liquid disinfectant by boiling the liquid at low temperature (room temperature).

As such, the disinfectant which is vaporized by pneumatic ultrasonication into a mist state is very small, so that it can be directly sprayed onto the object to sterilize, disinfect or kill the object.

However, in the present invention, in order to finely cut the mist disinfectant generated in the pneumatic ultrasonic generator to a finer size, it is to be injected through the vacuum generating tank 31.

In general, the boiling conditions of the liquid, that is, the vaporization conditions are high pressure, low pressure rather than low temperature, and the vaporization is actively progressed in the high temperature state.

The present invention is to reduce the pressure inside the vaporization tank 12 by the vacuum generated in the vacuum generating tank 31 so that the disinfectant in the vaporization tank 12 is vaporized in a large amount at low temperature and vaporized into fine particles, the operation The explanation is as follows.

A certain amount of liquid disinfectant 11 is injected into each vaporization tank 12, and a vacuum fan (vacuum pump) 33 of the vacuum generating tank 31 is operated to reduce the pressure of the vacuum generating tank 31. When lowering, the air inside the vaporization tank 12 is discharged through the supply pipe 25, and the air pressure inside the vaporization tank 12 is lowered, and the heater 18 attached to the lower side of the vaporization tank 12 is operated. By increasing the temperature of the disinfectant 11, the disinfectant 11 will promote vaporization.

That is, when the temperature of the disinfectant 11 is increased and the air pressure inside the vaporization tank 12 is lowered, the amount of vaporization is increased than usual.

In addition, when the piezoelectric vibrators 19 and 20 that operate by electricity inside the vaporization tank 12 to generate ultrasonic waves are operated, the disinfectant in a stable liquid state is changed to an unstable state, so that the disinfectant 11 is pneumatically compressed. Boiled and vaporized by the ultrasonic generator 16, the vaporized particles are vaporized in a very small state.

When the pneumatic ultrasonic generator 16 of the vaporization tank 12 is operated to vaporize the disinfectant 11, a vacuum fan (vacuum pump) of the vacuum generating tank 31 is operated to operate the vacuum generating tank 31 and When the vacuum pressure of the vaporization tank 12 reaches a certain degree, the valve 26 of the supply pipe 25 is blocked, and the vaporization tank 12 and the vacuum generating tank 31 are shut off, and then inside the vaporization tank 12. The compressed air is applied to the pneumatic ultrasonic generator 16 to boil off the disinfectant that generates ultrasonic waves.

The pneumatic ultrasonic generator 16 operates to vaporize the disinfectant 11, and when the pressure inside the vaporization tank 12 is increased, the valve 26 of the supply pipe 25 is opened to vaporize the vaporization tank 12 inside. When the disinfectant is introduced into the vacuum generating tank 31 through the supply pipe 25, it is diffused by the impact diffusion plate 35 in the conical form below the inner side of the vacuum generating tank 31. The vaporized disinfectant, which is in close contact with the collision diffusion plate 35 and its main surface, has a small particle size, is sucked up by the vacuum fan (vacuum pump) 32, and then discharged into the discharge pipe 32.

The vaporized disinfectant that is raised in the vacuum generating tank 31 is discharged to the discharge pipe 32 while being rotated in a tornado phenomenon by the rotationally inclined plate 36.

The vaporized disinfectant of the vacuum generating tank 31 has a high density phenomenon while its particles are very small, so that air is introduced into the vacuum generating tank 31 to disperse and adjust the concentration of the disinfectant. Will be adjusted.

To this end, the upper and lower supply mechanisms (37) (38) for introducing external air above and below the vacuum generating tank (31) and the air introduced therethrough reduces the density of the high-density vaporized disinfectant. The amount of air flowing into the opening and closing plates 37 'and 38' inside the upper and lower supply mechanisms 37 and 38 is arbitrarily adjusted.

One cycle is completed by discharging the vaporized disinfectant introduced into the vacuum generating tank 31 to the discharge pipe 32 through the vacuum fan (vacuum pump) 33, and at the same time, the upper and lower supply mechanisms 37 After closing the upper and lower supply mechanisms of the opening and closing plates 37 'and 38' of (38), the vacuum fan (vacuum pump) 33 is operated to reduce the pressure in the vacuum generating tank 31 to The cycle is repeated repeatedly to produce a vaporized fine disinfectant continuously.

The vaporization tank 12 has a piezoelectric vibrator 19, 20 that operates by electricity in addition to the pneumatic ultrasonic generator 16 to generate ultrasonic waves, the piezoelectric vibrator 19, 20 is a liquid disinfectant Vibration (11) causes the bonding state of the disinfectant 11 to become unstable and promotes vaporization.

The liquid disinfectant collected under the vacuum generating tank 31 is drained through the drain valve 39 or conveyed to the vaporization tank 12 through the conveying pipe 27.

In addition, the pressure gauge 24 of the upper connection pipe 13 connecting the vaporization tank 12 to each other detects the pressure in the vaporization tank 12,

The temperature sensor 15 of the lower connection pipe 14 detects the temperature of the disinfectant 11 inside the vaporization tank 12.

Prevention work such as sterilization, insecticide and disinfection are carried out throughout the society.

That is, in rural areas, disinfectants are sprayed for disinfection of barns, houses, etc., and crops of rice, fruit trees, and vegetables are periodically sprayed to prevent pests. In addition, in urban areas, the inside of the house is periodically disinfected to exterminate pests such as flies, mosquitoes, and cockroaches.

In addition, prevention of infectious diseases and other diseases are periodically conducted.

However, conventional devices for disinfecting disinfectants, such as disinfectants and insecticides, can be seen to form disinfectants in the form of smoke screens by using combustion heat or combustion gases generated by burning combustible materials such as diesel oil or thinner. After dilution, it can be seen spraying through the nozzle.

Smoke disinfection occurs in the process of burning combustibles, and pollutants such as carbon dioxide and nitrogen oxides are also generated, and it can be seen that the performance of the disinfectant solution is degraded by the heat of combustion, and the method of spraying the disinfectant solution through the nozzle is excessive. It will cause the use of disinfectant solution, and if it penetrates the ground, it can be seen that it will acidify the soil by removing beneficial microorganisms in the ground.

Disinfectant dispersing device according to the present invention, regardless of whether the disinfectant is oily or aqueous, vaporizes into fine particles to dig into every corner in the smoke state and sterilize sterilization effect, the sterilization effect is great, and can disinfect a large range with a small amount of disinfectant It is economically advantageous, and since the disinfectant solution is evaporated finely with the liquid, it is widely and evenly sprayed, so that not only the extermination of pests such as flies, mosquitoes, cockroaches, etc., but also microscopic germs can be completely eliminated. As such, the present invention is expected to save the disinfectant due to the dispersion in the gaseous state, and to prevent the overuse of the disinfectant, thereby preventing another damage caused by the disinfectant in advance.

In addition, the present invention is a very useful invention that can be usefully used as sterilization, vaporization of insecticides, as well as sterilization of bacteria used in biological and chemical warfare and chemical detoxification neutralizer spreader.

In particular, the present invention is excellent in the spreadability and permeability by vaporizing and spraying the disinfectant into extremely fine particles by ultrasonic waves, it can effectively eradicate various harmful bacteria hiding in the airborne floats and corner baskets, fine particles The disinfectant sprayed on is sterilized and neutralized by contaminants without being damaged or corroded to electronic equipment such as computers, documents, interiors, and other indoor objects when sprayed into contaminated rooms. It is a very useful invention that can be usefully used.
