に至つた。BACKGROUND OF THE INVENTION Attempts have been made to utilize white smoke from dry ice for the purpose of enhancing display effects at banquets, shops, etc., and theatrical production effects. Then, a dry ice white smoke generator was proposed (for example, JP-A-53-
53580, U.S. Pat. No. 55-132133).

不満足を内在させている。 Conventional white smoke generators embody a method of sublimating dry ice in hot water to generate white smoke, and when dry ice is placed in water,
In order for ice to adhere around the dry ice and the generation of white smoke to rapidly decrease, it must be sublimated with hot water of 60℃ or higher, and hot water of 60℃ or higher must be used before the time required to generate white smoke. Until this happens, there is a time loss in having to heat the water with an electric heater, and a large amount of electricity is required because the water must be kept at a temperature of 60°C or higher at all times. Furthermore, when dry ice is placed in hot water, it sublimes rapidly, and the generation of white smoke decreases in proportion to this, making it difficult to construct a structure to generate a certain amount of white smoke. If the amount of ice is less than 1/3 of the dry ice stored in the device, white smoke will not be generated significantly and loss will increase.In addition, dry ice has a sublimation temperature of -78.9℃, and it sublimes during storage. Due to the rapid loss of ice, it is necessary to prepare more dry ice than necessary. As described above, the generation of white smoke from dry ice has inherent technical and economical dissatisfaction as described above.

ある。Problems to be Solved by the Invention In view of the above-mentioned problems associated with the generation of white smoke from dry ice, the present invention is embodied in a device that generates white smoke using liquefied carbon dioxide gas, and is technically and economically efficient. It is an object of the present invention to provide a white smoke generating device that can be used in various fields.
問題点を解決するための手段
この発明は、液化炭酸ガスを水中に噴射させて

煙発生の装置に具体化した構成は次のとおりであ
る。Means for Solving the Problems This invention is based on generating white smoke by injecting liquefied carbon dioxide gas into water, and the configuration of the white smoke generation device is as follows. be.
白煙を発生させる水槽と、水槽内の水温を調整

射ホーンと、水飛沫防止板との主要部から構成さ
れる。 It consists of a water tank that generates white smoke, a heating device that adjusts the water temperature in the tank, a liquefied carbon dioxide injection horn equipped with a dispersion mechanism, and a water splash prevention plate.
作 用 上記構成の作用について以下に説明する。Effect The operation of the above configuration will be explained below.
液化炭酸ガスを水槽内の水中に直接噴射させる
と、噴射音が発生し、騒音源となるために、椀状

水中に液化炭酸ガスを噴射すると微細なスノー状
ドライアイスとなり、水温が１〜２℃以上あると
速やかに昇華して白煙を発生する。噴射ホーンを
完全に水中に水没させることにより、噴射音が水
に遮られ、噴射音が聞こえなくなる。 When liquefied carbon dioxide is injected directly into the water in an aquarium, injection noise is generated, which becomes a noise source. It becomes snow-like dry ice, and if the water temperature is 1 to 2 degrees Celsius or higher, it quickly sublimates and produces white smoke. By completely submerging the injection horn in water, the injection sound is blocked by the water and becomes inaudible.
液化炭酸ガス噴射ホーンから液化炭酸ガスを水
中に噴射させると、その噴射圧によつて水が飛散

口部内に数段の水飛沫防止板を設ける。飛散され
た水は各防止板に当り落下するので白煙に同伴さ
れる水の飛沫量を僅少ならしめる。 When liquefied carbon dioxide gas is injected into water from the liquefied carbon dioxide gas injection horn, the water is scattered by the injection pressure and is scattered outside through the upper opening of the aquarium, so the dispersion mechanism installed at the top of the injection horn Water splashing can be reduced by injecting liquefied carbon dioxide gas through adiabatic expansion, but to further prevent water splashing to the outside, several levels of water splash prevention plates are installed inside the upper opening of the aquarium. establish. Since the scattered water hits each prevention plate and falls, the amount of water splashed along with the white smoke is minimized.

発生する。所望の白煙の流を得るために水温を調
節する水没型の電気ヒーター等の加熱装置が水槽
内に設けられる。 Liquefied carbon dioxide is injected toward the bottom of the tank from an injection horn submerged in water, becoming fine snow-like dry ice, which sublimes and generates white smoke. If the water temperature is below 10℃, the floor surface and White smoke that crawls on the ground and rises when the temperature exceeds 20°C is generated. A heating device, such as a submerged electric heater, is provided within the water tank to adjust the water temperature to obtain the desired white smoke flow.
噴射ホーンは噴射される液化炭酸ガスによつて
ホーンの表面に水が凍結して来るが、多量の白煙
を必要とする装置の場合には、噴射ホーンの内部
に電気ヒーターを内設し、ホーンを加熱すること
により運転に支障のないように凍結を防ぐことが
できる。 Water freezes on the surface of the injection horn due to the liquefied carbon dioxide being injected, but in the case of equipment that requires a large amount of white smoke, an electric heater is installed inside the injection horn. By heating the horn, it is possible to prevent it from freezing so that it does not affect operation.
また、多量の白煙を必要とする装置において
は、水槽を防音構造とすることで、噴射音の防音
が図られる。 In addition, in devices that require a large amount of white smoke, the water tank has a soundproof structure so that injection noise can be soundproofed.
液化炭酸ガスは、サイフオン管を内蔵した液化
炭酸ガス高圧容器の容器弁に連結される導管によ
り、電磁弁を経て分散機構を備えた噴射ホーンか
ら水中に噴射される。 The liquefied carbon dioxide gas is injected into the water from an injection horn equipped with a dispersion mechanism via a solenoid valve through a conduit connected to a container valve of a high-pressure liquefied carbon dioxide gas container with a built-in siphon tube.
液化炭酸ガス高圧容器から液化炭酸ガスを導管

し、このタイマーは積算計に連動させ、この積算
計から液化炭酸ガスの使用量を判定し、液化炭酸
ガス高圧容器の取替の目安とする。 Since the liquefied carbon dioxide gas is supplied from the liquefied carbon dioxide high-pressure container to the injection horn through the conduit, the amount of liquefied carbon dioxide gas used in the container cannot be measured visually from the outside, so the solenoid valve installed in the conduit is activated by a timer. This timer is linked to a totalizer, and the amount of liquefied carbon dioxide used is determined from this totalizer, and is used as a guideline for replacing the liquefied carbon dioxide high-pressure container.

している。 A water temperature controller is provided under the water in the aquarium, and the input source of the heating device is opened and closed in response to an activation signal to adjust the water temperature. Furthermore, you can use a liquid level gauge to tell whether or not a predetermined amount of water is stored in the water tank, but in order to be sure, you can use the electrode rod of a so-called dry-burn prevention device, which is made up of an electrode rod and a relay. is installed in the water tank, and the relay circuit is connected to the heating device to prevent dry firing.
