Description

Cooling prevention device for industrial liquefied gas cylinder {A COOLING PREVENTION DEVICE OF LIQUEFIED GAS TANK}

The present invention relates to an apparatus for preventing cooling of a liquefied gas cylinder, and more particularly, to an apparatus for preventing cooling of an industrial liquefied gas cylinder that can maintain a surface of a gas cylinder in which a liquefied gas used in an industrial site is stored at room temperature.

In general, liquefied gas such as inert gas (hydrogen gas, argon gas or helium gas) obtained by decomposing ammonia gas, or neutral gas such as nitrogen is mainly used in industrial sites.

Such liquefied gas is usually stored in a gas cylinder equipped with a valve device, the valve device of the gas cylinder is connected to the industrial gas supply line. Therefore, when the valve device is opened, the liquefied gas in the gas cylinder is vaporized and supplied to the required industrial site through the gas supply line.

However, if the liquefied gas is continuously used for a long time, as the liquefied gas escapes, the surface temperature of the gas cylinder drops below the dew point temperature. As a result, the liquefied gas stored in the gas cylinder does not easily escape and remains. have.

In other words, as the surface temperature of the gas cylinder is cooled, the liquefied gas stored therein is also kept cooler and cannot be ejected to the outside smoothly. Particularly, this phenomenon occurs during the winter when the outdoor temperature drops below zero. It occurs badly, and for this reason, considerable resources are wasted.

The present invention is to solve this problem; It is an object of the present invention to provide an apparatus for preventing cooling of an industrial liquefied gas cylinder which can prevent gas residual phenomenon by maintaining the surface temperature of the gas cylinder at room temperature even while the liquefied gas is evaporated.

The present invention for achieving this object is;

An apparatus for preventing cooling of a liquefied gas cylinder for preventing the surface of the gas cylinder from being cooled below a dew point temperature during the continuous extraction and use of the ammonia liquefied gas from an industrial gas cylinder containing an ammonia liquefied gas;

Cooling prevention device; It is characterized in that it comprises a water tank in which most of the gas cylinders are accommodated with ease and water is stored therein, a heater for directly heating the water stored in the water tank to maintain a predetermined temperature, and a controller for controlling power supply to the heater.

In addition, the cooling prevention device; It is characterized in that it comprises a supply pipe for supplying water at room temperature, and a shower nozzle provided at the end of the supply pipe and spraying water on the surface of the gas cylinder in a shower manner.

According to such a structure, since gas cylinder surface temperature is always kept at normal temperature by hot water, gas ejection becomes smoother.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

First, the cooling device for the industrial liquefied gas cylinder according to the first embodiment of the present invention, as shown in Fig. 1 and 2, the water tank 10 is stored, and the water stored in the water tank 10 Heater 20 and a controller 30 for controlling the power supply to the heater 20.

The water tank 10 is composed of a metal housing having an open top, and a plurality of liquefied gas cylinders 1 together with water are accommodated therein.

The heater 20 is a kind of electric heater extending a predetermined length in a rod type, and is supplied with power through the controller 30 to generate heat. Such a heater 20 is preferably disposed to extend downward from the central portion of the water tank 10 to be completely accommodated in the water in the water tank 10.

And the controller 30 is a control box 31 on the housing provided in the upper portion of the center of the water tank 10, and the control knob (not shown) provided in the control box 31 to control the current supply directly to the heater 20 Equipped with. In addition, since the heaters 20 are disposed to extend below the control box 31, the heaters 20 are completely housed in water in the water tank 10.

Next, the operation of the liquefied gas cylinder cooling prevention apparatus according to the present invention configured as described above and the effects thereof will be described.

First, a plurality of liquefied gas cylinders 1 are introduced into a water tank 10 in which water is stored. At this time, the liquefied gas cylinder 1 is preferably accommodated in the water in the water tank 10 90% or more except for the upper portion provided with the valve device (2).

Then, when power is applied to the heater 20 by operating the control knob of the controller 30, the water in the water tank 10 is maintained at a predetermined temperature while heating. At this time, it is preferable to keep the water in the water tank 10 about 70-80 degreeC. Therefore, the surface temperature of the liquefied gas cylinder 1 is also maintained at a predetermined temperature by the heated water.

When the valve device 2 of the liquefied gas cylinder 1 is opened in this state, the liquefied gas stored in the liquefied gas cylinder 1 is vaporized and supplied to the industrial site through the gas supply line 3.

At this time, the surface temperature of the liquefied gas cylinder 1 is about to be cooled due to the gas ejection pressure. Since the liquefied gas cylinder 1 is immersed in hot water, the surface of the liquefied gas cylinder 1 is always maintained at room temperature. In fact, when the temperature of the water is maintained at about 70 ~ 80 ℃ surface temperature of the liquefied gas cylinder (1) is maintained about 30 ~ 40 ℃.

As a result, even if the gas is ejected from the liquefied gas cylinder 1 for a long time, its surface temperature is always maintained at room temperature, so that no gas residual phenomenon occurs in the liquefied gas cylinder 1 and is discharged to the outside while being 100% completely vaporized.

On the other hand, the technical idea of preventing the freezing phenomenon on the surface of the gas cylinder 1 by maintaining the liquefied gas cylinder 1 at room temperature is not limited thereto, as shown in Figure 3, even if sprayed hot water in the shower method The purpose can be achieved.

That is, the cooling device for the industrial liquefied gas cylinder according to the second embodiment of the present invention, as shown in Figure 3, the hot water supply pipe 40 is supplied with the hot water heated in the boiler, the end of the hot water supply pipe 40 It is provided in the shower nozzle 50 for spraying hot water to the liquefied gas cylinder (1) surface.

The hot water supply pipe 40 is for supplying hot water heated to a considerable temperature at the boiler side to the place where the liquefied gas cylinder 1 is located.

The shower nozzle 50 is for spraying hot water to the surface of the liquefied gas cylinder 40 in a shower manner, and a plurality of shower nozzles 50 are disposed at regular intervals at ends of the hot water supply pipe 40. In addition, each shower nozzle 50 is provided with a valve 51 for controlling hot water injection.

Therefore, when the liquefied gas cylinder 1 is disposed directly below the shower nozzle 50 and the valve 51 is opened, hot water is sprayed from the shower nozzle 50 onto the surface of the liquefied gas cylinder 1 in a shower manner. For this reason, the surface of the liquefied gas cylinder 1 is always maintained at room temperature by hot water, whereby the liquefied gas inside the liquefied gas cylinder 1 is discharged to the outside while completely vaporized. Meanwhile, another embodiment of the present invention In the example of spraying the hot water heated in the boiler in the shower method, but not limited to this can be achieved through the purpose of the present invention by connecting the supply pipe directly to the tap water, even at room temperature of course.

As described in detail above; According to the apparatus for preventing cooling of an industrial liquefied gas cylinder according to the present invention, the surface of the liquefied gas cylinder is always maintained at room temperature by hot water. Therefore, the liquefied gas cylinder is always maintained at room temperature even while the liquefied gas cylinder is ejected as it is vaporized, there is an effect that can prevent the gas residual phenomenon in the liquefied gas cylinder. In addition, since the liquefied gas is ejected while completely vaporized, there is an advantage that can prevent the waste of resources.
