Inert Gas Storage Venting Layout for Low-Concentration Discharge
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing storage facilities face challenges in suppressing the concentration of inactive gas discharged outside the storage space, which can restrict operator movement or require stopping the inactive gas supply during operations, due to high inactive gas concentrations in the discharged gas.
Innovation Solution
Incorporating a gas discharge portion with a restricting orifice portion below the storage sections, which mixes the discharged gas with the storage space gas, and utilizing a communicating space and external communicating portion to further dilute the inactive gas concentration, while also employing a discharge promoting portion like fans to facilitate gas discharge.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the gas discharged from the container is directly discharged to the outside of the storage space, then the discharge structure is simple, but the inactive gas concentration in the discharged gas is high
Solution Approach 1:
The patent introduces an intermediary mixing space between the container discharge and the external environment. The gas discharged from the container first enters the storage space where it mixes with the storage space atmosphere, then the mixed gas is discharged through the gas discharge portion. This intermediary mixing process dilutes the inactive gas concentration before external discharge, resolving the contradiction between simple discharge structure and low inactive gas concentration.
2Length of moving object
If the restricting orifice portion is positioned above the storage sections, then the gas discharge path is short, but the gas mixing efficiency is low
Solution Approach 1:
The patent positions the restricting orifice portion below the storage sections, utilizing the vertical dimension effectively. This positioning allows the gas discharge path to extend downward through the storage space, increasing the interaction time and mixing distance between the discharged gas and storage space atmosphere. The gas must travel through the storage space volume rather than taking a direct short path, thereby improving mixing efficiency while maintaining a reasonable discharge path length.

Function Achieved in This Case
This configuration effectively reduces the inactive gas concentration in the discharged gas, allowing for safe operator movement and continuous gas supply by promoting gas mixing and controlled discharge within the storage facility.
Implementation Method 1
the gas discharge portion includes a restricting orifice portion serving as a restricting portion that restricts a flow rate of gas
Implementation Method 2
the storage device includes a communicating space below the region where the storage sections are disposed in the inside of the storage space, and an external communicating portion that communicates the communicating space with the outside of the storage space

AI summary
A storage facility is achieved that is capable of suppressing, with a simple configuration, the inactive gas concentration in the gas discharged to the outside of a storage space. The storage facility includes a storage device including a plurality of storage sections in an inside of a storage space formed so as to be partitioned from the outside, and an inactive gas supply portion that supplies inactive gas to an inside of a container stored in the storage section. The storage device includes a gas discharge portion that discharges, to the outside of the storage space, gas within the storage space that contains the gas discharged from the container. The gas discharge portion includes a restricting orifice portion serving as a restricting portion that restricts a flow rate of gas, and the restricting orifice portion is formed below a region where the storage sections are disposed.
