産業上の利用分野
本考案はLPG、LNG等の貯蔵大型タンク等に
おける貯蔵液体を混合撹拌するための混合ノズル
に関するものである。[Detailed Description of the Invention] Industrial Application Field The present invention relates to a mixing nozzle for mixing and agitating liquids stored in large tanks for storing LPG, LNG, etc.
従来の技術
たとえばLPG、LNG等の液化ガスの貯蔵大型

ものである。Means for Solving the Problems In order to solve the above problems, the mixing nozzle of the present invention has a central part formed in a cylindrical shape (circular or square cross section), a receiving port at the base end, and a distal end. A nozzle body is provided with a tapered jet nozzle, and a partition plate is provided from an intermediate position in the center of the nozzle body to the jet nozzle to divide the downstream side of the nozzle body into two chambers, and one of the chambers has a deceleration chamber.

撹拌させられるものである。Effect In the above configuration, when the mixing nozzle is installed in the liquefied gas circulation path of a large liquefied gas storage tank, for example, the liquefied gas that enters the central part from the intake port is divided into two streams by the partition plate, and one stream flows into one chamber. When it hits the filling material, it is decelerated and is ejected from the ejection port relatively slowly. The other flow passes through the other chamber and is forcefully jetted out from the spout. In front of the spout, one stream that is slowly ejected and the other stream that is ejected vigorously interfere with each other, thereby generating a vortex and mixing and stirring the liquefied gas.

Reference numeral 1 denotes a large tank for storing liquefied gas 2 such as LPG or LNG, and 3 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 central portion 6A formed in a cylindrical shape (or a rectangular tube shape) and a receiving port 6B at the base end. The nozzle main body 6 has a tapered jet nozzle 6C at the tip, and the nozzle main body 6 is arranged from an intermediate position between the central part 6A and the nozzle nozzle 6C, and the downstream side of the nozzle main body 6 is divided into two chambers. A partition plate 9 dividing the chamber 7 and 8, a large number of deceleration beads 10 filled upstream of one chamber 7, and a plurality of deceleration beads 10 disposed downstream of the central portion 6A across both chambers 7 and 8.

る。なお第２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 entered the mixing nozzle 5 is divided into two streams A and B by the partition plate 9, one stream A hits the filling 10 in the other chamber 7 and is decelerated, and the flow is changed by the rectifier plate 11. After this, the water is ejected relatively slowly from the ejection port 6C. The other flow B passes through the other chamber 8 and is adjusted by the current plate 11, and then flows through the jet nozzle 6.
It is made to gush forcefully from C. and spout 6
In front of C, one-sided flow A is slowly ejected.
and the other flow B which is ejected vigorously interfere with each other, thereby generating a strong two-dimensional vortex C, which mixes and stirs the liquefied gas 2. Note that in FIG. 2, A is a velocity distribution diagram.
