Embodiment 1

[0044] figure 1 It is a figure which shows the structure of Example 1 of the liquefied gas supply system concerning this invention. like figure 1 As shown, the liquefied gas supply system of the present invention is composed of the following: a plurality of (n) containers 1-1 to 1-n (with the first container being 1-1 and the nth container being 1-n additional labels to indicate, the same below); measuring device 2-1 ~ 2-n; heating source 3-1 ~ 3-n; heating amount measuring sensor 4-1 ~ 4-n; thermostat 5-1 ~ 5- n; heating output devices 6-1 to 6-n; measured value calculation comparator 7, connecting pipe 8, cut-off valve 9, and liquefied gas 10-1 to 10-n in each container.

[0045] Containers 1-1~1-n are containers of standard sizes that can be easily obtained, and their capacities are all the same. Before they are installed in this supply system, the amount of liquefied gas 10-1~10-n in each container is known (this embodiment 1 is weight). The containers 1-1 to 1-n are...

Embodiment 2

[0059] Figure 5 It is a figure which shows the structure of Example 2 of the liquefied gas supply system concerning this invention. replaces the above figure 1 The measuring devices 2-1 to 2-n in the container have liquid level sensors 11-1 to 11-n for detecting the liquid level (residual amount) of the liquefied gas as means for measuring the remaining amount of liquefied gas in the container. And, put the above figure 2 The measured values ​​of a plurality of (n) measuring devices 2-1~2-n taken into the measured value calculation comparator 7 are replaced by L-1~L-n as liquid level sensors 11-1~11-n, so that The average value of all measured values ​​calculated by the measured value calculation comparator 7 is La, the judgment value of the measured value calculation comparator 7 is D, and the stop signal output from the measured value calculation comparator 7 by this judgment is OFF-1 to OFF -n. and, in Figure 5 In , as an example of detecting the liquid level, a fl...

Embodiment 3

[0063] Image 6 It is a figure which shows the structure of Example 3 of the liquefied gas supply system concerning this invention. its to the above figure 1 Connection shutoff valves 12-1 to 12-n are added.

[0064] Refer to the following Image 6 Example 3 will be described. The operation in the normal supply state and the above figure 1 , figure 2 As explained, in the state where each container is connected, it is not necessarily in the supply state, the liquefied gas does not necessarily decrease, and there are cases where the consumption side stops, the flow of the supply gas supply is interrupted for a long time, or the shut-off valve 9 is closed and it is on standby. Case.

[0065] In this state, the liquefied gas in each container is repeatedly moved and filled from the high pressure to the low pressure between the containers due to the slight difference in vapor pressure caused by the different temperature, so as to keep the balance. Especially when the cut-of...

Abstract

A liquefied gas supply system and method can supply the liquefied gas in a plurality of liquefied gas containers uniformly to supply huge amount of gas constantly. A liquefied gas supply system comprises a plurality of liquefied gas containers 1 , a detector 2 installed in each of the containers 1 to detect a volume of liquefied gas contained in each of the containers 1 , a heating device 3 installed on each of the container 1 and a control device 7 to process information obtained by each of the detectors 2 and control each of the heating devices 3 . The control device 7 controls each of the heating devices 3 based on a value obtained by overall processing of the information obtained by each of the detectors 2.

Description

technical field [0001] The invention relates to a liquefied gas supply system and a supply method formed by heating and temperature-regulating a plurality of liquefied gas containers. Background technique [0002] When a large amount of liquefied gas with low vapor pressure and low evaporation capacity at normal temperature is consumed, in order to improve the evaporation capacity, the method of increasing the evaporation surface area of ​​the liquefied gas and increasing the temperature of the liquefied gas is adopted. And as the means for realizing these methods, there are enlarging the radius of the container filled with the liquefied gas, arranging a plurality of standard-sized containers in parallel, and heating the container containing the liquefied gas. And its combination has been studied: a plurality of readily available standard-sized containers can be arranged side by side, or heated at the same time, and a large amount of liquefied gas can be stably supplied whil...
