この考案は、低温液化COガス等の毒性低温液
化ガスを貯蔵する毒性低温液化ガス貯蔵装置に関

Traditionally, toxic gases such as carbon monoxide have been extracted from converter gas, etc., using the absorption liquid separation method (the removal of carbon monoxide from converter gas).
Cosorb method (COsorb method in which CO components are absorbed and recovered with a toluene solution of aluminum copper tetrachloride) and PSA method (method in which CO is adsorbed and concentrated using an adsorbent such as zeolite)
has been adopted. These methods are generally installed in steel plants equipped with converters, and recover CO in gaseous form from the raw material gas there, which is then used as a raw material for acetic acid, higher alcohols, etc. However, recently, in addition to the above-mentioned raw materials for acetic acid and higher alcohols, carbon dioxide is considered to be the most important carbon source in C1 chemistry, and has been given importance as a raw material for the production of polycarbonate resins, for example. However, as mentioned above, since the CO production equipment is large-scale, installing this equipment in a polycarbonate resin manufacturing factory requires a lot of expense. Furthermore, transporting CO from CO production equipment installed at steel plants and the like is also problematic because CO is gaseous and takes up a large volume.
そこで、本考案者は、COをガス状で製造する

い。 Therefore, as a result of repeated research to produce CO in liquid form instead of gaseous form, the inventor developed a device that produces CO in liquid form by applying the cryogenic liquefaction separation method. A patent application has already been filed (Japanese Patent Application No. 189401-1983). And liquefied CO like this
If the polycarbonate resin is directly supplied to the above-mentioned polycarbonate resin manufacturing factory, no large-scale equipment is required and the efficiency is extremely high.

However, when transporting or storing low-temperature liquefied CO to the above-mentioned factories, the vaporized gas is extremely toxic, so it is not possible to release the vaporized gas from storage devices such as lorries or storage tanks. Must be avoided. Generally, in an adiabatic storage device for liquefied gas, a safety valve is installed to prevent the device from being destroyed due to a rise in internal pressure due to evaporation of the internal liquefied gas, and when the pressure rises, internal vaporized gas is released from the safety valve to reduce the pressure inside the device. I am trying to keep it below a certain level. However, as mentioned earlier, CO gas is extremely toxic, so it cannot be released from the safety valve. Therefore, unless this problem is solved, it is impossible to supply and store the above-mentioned low-temperature liquefied CO.
この考案は、こにような事情に鑑みなされたも

置の提供をその目的とする。 This invention was devised in view of the above circumstances, and its purpose is to provide a toxic low-temperature liquefied gas storage device that can safely store highly toxic low-temperature liquefied gas such as low-temperature liquefied CO.

In order to achieve the above object, the toxic low-temperature liquefied gas storage device of this invention has a condenser installed in a heat insulating layer between the inner tank and the outer layer, and a toxic gas stagnant in the upper space inside the inner tank. an inlet pipe for introducing the liquefied toxic gas into the condenser, a return pipe for returning the liquefied toxic gas generated in the condenser to the inner tank, and a pipe for supplying the non-toxic low-temperature liquefied gas as cold to the condenser. The condenser is equipped with a storage container for low-temperature liquefied non-toxic gas supplied through the condenser, and a discharge pipe for discharging to the outside the non-toxic low-temperature liquefied gas that has completed its cooling action in the condenser and has been vaporized.

No pressure rise occurs in the inner tank, and as a result, no non-toxic gas is released into the atmosphere. Further, since the above device has a simple structure, it has the advantage that it can be applied not only to fixed storage tanks but also to tank trucks and the like.

FIG. 1 shows a longitudinal section of an embodiment of this invention. In the figure, 1 is an inner tank for storing low-temperature liquefied CO gas 1a, and 2 is an outer tank. A condenser 3 is provided in the upper space of the inner tank 1 and the outer tank 2 to liquefy the vaporized product of the low-temperature liquefied CO gas and to prevent the pressure inside the inner tank from increasing. This condenser 3 is equipped with a condensing pipe 4 inside, and one end of the condensing pipe 4 serves as an introduction pipe section 4a that opens into the upper space of the inner tank 1, and the other end serves as a return pipe section 4b that opens into the upper space of the inner tank 1. It opens into the upper space of the inner tank 1. As shown in the figure, the entire condenser 3 is arranged at an angle so that the introduction pipe portion 4a side is higher. One end of the condenser 3 is connected to one end of a supply pipe 5, and the other end of the supply pipe 5 is connected to a pipe 7 with a control valve 8 extending from a liquid nitrogen storage tank 6. The other end of the condenser 3 is connected to a discharge pipe 9 equipped with a discharge valve 10. Reference numeral 12 denotes a gas pressure gauge that measures the pressure of CO gas in the upper space of the inner tank 1. The stiff gas pressure gauge 12 controls the opening and closing of the control valve 8, and controls the opening of the cold and low temperature gas supplied into the condenser 3. The amount of liquefied nitrogen gas is controlled, thereby controlling the amount of vaporized gas liquefied in the condenser 3, thereby making the pressure in the inner tank 1 constant.

い。 This device is configured as described above, so
The low-temperature liquefied CO gas 1a stored in the inner tank 1 is vaporized, and the CO gas is densely accumulated in the upper space.
When the internal pressure increases, the CO gas is introduced into the condensing tube 4 from one end of the condensing tube 4, is cooled and liquefied by the cold low-temperature liquefied nitrogen gas, and returns to the inner tank 1. Therefore, an abnormal increase in the pressure in the inner tank 1 due to the gas pressure of the CO gas does not occur, and a situation where highly toxic CO gas is released from the safety valve 13 does not occur.

In this embodiment, CO gas is passed through the liquid nitrogen in the condensing tube 4 and into the internal space of the condenser 3 to liquefy the CO gas. The other parts are the first
It is the same as the figure, and the effect is also the same.

しうる。 Although liquefied N 2 is used as the non-toxic low-temperature liquefied gas in the above embodiment, an inert gas such as liquefied argon may be used instead. That is, the non-toxic low-temperature liquefied gas in this invention includes inert gases such as liquefied N 2 and liquefied argon. In addition, as a toxic low-temperature liquefied gas to be stored,
It is possible to store not only the low-temperature liquefied CO gas mentioned above, but also all kinds of other toxic low-temperature liquefied gases.

The toxic low-temperature liquefied gas storage device of this invention is configured as described above, so that the pressure inside the inner tank is always maintained below the specified pressure, and as a result, the toxic gas is released into the atmosphere from the safety valve. Without a problem,
Poisonous gases can be stored extremely safely.
Therefore, unlike in the past, there is no need to install CO gas production equipment in the factory that requires it; it is now sufficient to simply install a storage device in the factory and supply toxic low-temperature liquefied gas there. , it will be possible to realize a significant reduction in equipment costs for factories and other facilities that use toxic low-temperature liquefied gas.
