ら、コストアツプになるものである。Problems to be Solved by the Invention According to the above-mentioned conventional configuration, since the liquefied gas is simply circulated, the stratification phenomenon cannot be completely eliminated. Therefore, it is possible to install a mixing and stirring device in the tank, but this would increase costs because the mixing and stirring device is relatively expensive and special power is required to operate the device. It is.

The spiral flow is made into a spiral flow by the jet, and after the flow speed is increased at the jet port, the spiral flow is injected into the tank to mix and stir the liquefied gas.

されている。Embodiment An embodiment of the present invention will be described below with reference to FIGS. 1 to 3. 1 is a large tank for storing liquefied gas 2 such as LPG or LNG, and 3 is a circulation pipe connecting the upper and lower parts of the tank 1, with a pump 4 interposed in the middle. Reference numeral 5 denotes a mixing nozzle connected to the discharge port of the circulation pipe 3 in the tank 1, which has a cylindrical central portion 6A, a receiving port 6B at the base end, and a small diameter jet at the tip. A nozzle body 6 having an outlet 6c, and a large number of spiral holes 7 on the downstream side of the central part 6A in the nozzle body 6.
The structural body 8 has a honeycomb-like cross section.

なお、第１図においてイは速度分布図である。 Hereinafter, the effects of the above configuration will be explained. First, when the pump 4 is activated, the upper part of the liquefied gas 2 in the tank 1 is sucked through the pipe 3.
It is discharged into the mixing nozzle 5. Then, the liquefied gas 2 that has entered the mixing nozzle 5 passes through the spiral hole 7 of the honeycomb structure 8, thereby forming a spiral rectification. The liquefied gas 2 formed in the spirally rectified flow has a faster flow rate when passing through the ejection port 6c, and is forcefully ejected into the tank 1. A strong vortex is formed over a relatively long distance in front of the ejection port 6c along the axial direction of the mixing nozzle 5, and mixes and stirs the liquefied gas 2 in the tank 1.
Note that in FIG. 1, A is a velocity distribution diagram.
