Regarding the portable chemical spraying machine used for spraying, liquefied carbon dioxide gas is especially used as the high-pressure gas to atomize the chemical solution, and the pressure of this liquefied carbon dioxide gas, that is, the ejection force due to the pressure of the vaporized gas, is utilized. This is what I did.

る。また薬剤と分子的結合を生じて薬剤の性質が
変化するおそれがある。 Traditionally, portable chemical sprayers that collide high-pressure, high-velocity gas with chemical liquid to atomize it have been using nitrogen vaporized by an installed vaporizer as the high-pressure gas to atomize the chemical liquid. Gas is commonly used. This nitrogen gas is compressed to high pressure and filled into cylinders, so even fairly large cylinders have a small gas capacity and run out in a short time, making it difficult to spray over large areas and over long periods of time in factories, schools, greenhouse cultivation, etc. It's something that doesn't exist. For example, with a 10Kg gas cylinder, gauge pressure of 6Kg/cm 2 , and gas amount of 125g/min, it will take about 15 minutes.
I'll run out. Of course, the larger the capacity, the larger the cylinder becomes, making it more inconvenient to handle. In addition, there is a risk that the properties of the drug may change due to the formation of molecular bonds with the drug.
そこで、本考案者は、薬液を煙霧化するための
高圧ガスとして、特に液化炭酸ガスの気化ガス圧
力による噴出力を利用せんとしたものである。 Therefore, the inventor of the present invention intended to use the ejection force caused by the vaporized gas pressure of liquefied carbon dioxide gas as a high-pressure gas for atomizing the chemical solution.

おそれもない。 In other words, if the vaporized gas pressure of liquefied carbon dioxide gas is used, there is no need to make the liquefied carbon dioxide gas cylinder as large as in the case of using a nitrogen gas cylinder, which is convenient for transportation and handling. Also, liquefied carbon dioxide does not require high-pressure gas handling qualifications. Moreover, carbon dioxide gas has no molecular bonding properties with the constituent components of currently developed drugs, and there is no fear of changing the properties of the drugs.

It also enables spraying work in dangerous areas such as electrical rooms.
といつた利点がある。There are some advantages.
しかし、薬液を煙霧化させる高圧ガスとして液
化炭酸ガスを使用するのは非常に困難で、従来一
般には実用化に適さないものとされている。 However, it is extremely difficult to use liquefied carbon dioxide gas as a high-pressure gas to atomize a chemical solution, and it has generally been considered unsuitable for practical use.
即ち液化炭酸ガスは非常な低温（約−20℃）で
あるため、これが充填されたボンベ内の気化ガス

圧バルブを通して連続気化させるのは減圧バルブ

つた。 In other words, liquefied carbon dioxide gas has a very low temperature (approximately -20℃), so if you take out the vaporized gas from a cylinder filled with it without a vaporizer, the amount of vaporized gas is small and it can only be used for a very short time. Furthermore, continuous vaporization of the required amount of liquefied carbon dioxide from a cylinder through a pressure reducing valve using an ordinary vaporizer has been unusable due to problems such as freezing of the pressure reducing valve.

After carbon dioxide gas is vaporized, it is configured so that it can be sent through a humidifying pressure regulator to obtain vaporized gas at the required pressure without fear of freezing the valve, etc.
It also allows for continuous use.

The spray gun is connected to a delivery route from a chemical liquid pressure delivery tank with a required capacity, which is provided so that the internal pressure can be adjusted using the vaporized gas pressure of liquefied carbon dioxide gas, and the delivery route from the carbon dioxide gas cylinder is connected to the spray gun.
In addition to having a built-in heater with multiple thermostats that can adjust the temperature to around 300 degrees Celsius, the number of heaters used can be switched and adjusted in several stages.
It is characterized in that a heating type pressure regulator equipped with a pressure reducing valve that can adjust the vaporized gas pressure to 4 to 7 Kg/cm 2 (gauge pressure) is installed subsequent thereto.

する。 To perform chemical spraying using the above-mentioned portable chemical sprayer, first, the warmer 6 and heating pressure regulator 10 installed in the delivery route 3 from the carbon dioxide gas cylinder 1 are installed.
Connect it to a suitable power source and turn it on. Once the built-in heaters 7, 11, and 12 have warmed up to the required temperature (around 300℃), check the connections of each part and turn off the main valve of carbon dioxide cylinder 1. Each valve in the delivery route is opened in order starting with the valve 5 for the chemical solution, and the valve 18 of the tank 15 for force-feeding the chemical solution is opened. Further, the pressure reducing valve 13 attached to the heating type pressure regulator 10 provided at the connection of the warming device 6 is adjusted to 6 kg/cm 2 (gauge pressure), and the valve 19 for adjusting the tank internal pressure is adjusted to a tank internal pressure of 0.75 kg/cm 2 (gauge pressure).

の種類と散布場所等に応じて決定できる。 Therefore, the liquefied carbon dioxide gas filled in the carbon dioxide gas cylinder 1 has a pressure inside the cylinder (gauge pressure of 45 to 120
Kg/cm 2 ) and is delivered in a liquid state by the siphon-type delivery structure, but the heater 6 installed in the delivery route 3
While passing through the interior, it is heated and vaporized continuously and reliably, and is sent out at the required pressure through the pressure reducing valve 13, and is ejected at a higher speed than the nozzle of the spray gun 4. At the same time, the chemical solution in the chemical solution supply tank 15 is delivered by the internal pressure of the tank, which is adjusted and maintained at an appropriate pressure using the pressure of the vaporized gas, and the suction action accompanying the gas ejection. The jetting force of this product atomizes ultrafine particles (medicine particle size: 5 to 50 microns) while maintaining uniformity. The drug particle size can be arbitrarily adjusted by appropriately adjusting the drug liquid pressure and gas pressure, and can be determined depending on the type of drug, the spraying location, etc.

時間を著しく短縮することができる。 The flying distance of the chemical liquid ejected from the nozzle of the spray gun 4 varies slightly depending on the particle size of the sprayed chemical and the specific gravity and viscosity of the chemical liquid used, but it can range from approximately 4 to 6 m. Combined with the amount of ejection, the working time can be significantly shortened.

でも充分散可能である。 Incidentally, even if the hose constituting the carbon dioxide gas delivery route and the chemical solution hose are quite long (5 to 100 m), the spraying operation can be carried out sufficiently as long as the aforementioned gas pressure and chemical solution pressure are appropriately adjusted. Furthermore, if a long handle (100 cm) is used as the spray gun 4, it is possible to disperse the spray thoroughly even in places where it is difficult to work inside, such as in the ceiling.

る。 As described above, according to the portable chemical sprayer of the present invention, liquefied carbon dioxide gas is taken out in a liquid state, and is heated by the heater 6 while passing through it to forcibly vaporize it. As a result, there is no shortage of vaporized gas during spraying work, and it can be used for quite a long time (for example, cylinder 10 kg: vaporized gas pressure 6 kg/
cm 2 (gauge pressure): Can be used continuously for 80 minutes at a gas flow rate of 125 g/min. In addition, the subsequent pressure reducing valve 13, that is, the pressure regulator, is especially equipped with a heater, so there is no need to worry about the pressure reducing valve freezing, and the liquefaction spraying can be carried out without any inconvenience by using the vaporized gas pressure of the liquefied carbon dioxide. It can be done. Moreover, since the plurality of heaters 7 built into the warmer can be adjusted and maintained at a temperature suitable for vaporizing liquefied carbon dioxide gas using a thermostat, there is no risk of the vaporized gas being heated excessively, and therefore, the chemical liquid can be fed under pressure. The chemical solution delivered from the storage tank 15 can be atomized at room temperature, and there is no risk of decomposition of the chemical due to heating or the like. Furthermore, since the heater 6 can switch and adjust the number of heaters 7 used in several stages, depending on the outside temperature, for example, it can be set to two stages, winter and summer, or to three stages, winter, spring/autumn, and summer. By switching the number of heaters used, it is possible to eliminate wasted power consumption, and it is also possible to adequately respond to changes in cylinder internal pressure due to outside temperature.
