Intelligent gas mixing system

Abstract

The invention provides an intelligent gas mixing system, relates to the technical field of gas supply, and aims to solve the problems that existing gas mixing is carried out in a manual manner, the required mixing dosage cannot be accurately mastered, so that the gas with an imbalance mixing ratio exists in a mixing device, the later re-mixing is influenced, and the manual mixing precision is low. The system comprises a gas inlet unit and is characterized in that the gas inlet unit is connected with a gas mixing unit, and a control unit is arranged on the left side of the gas mixing unit. Through arrangement of a computer in the control unit, intelligence of the mixing process is guaranteed, the safety problems of gas leakage and gas explosion in the whole mixing process are avoided, the gas mixing precision is high, the mixing efficiency is high, the labor intensity of workers is reduced, quantitative mixing can be achieved, and it is guaranteed that in the whole mixing process, precision is high, and mixed gas is high in practicability.

Description

technical field [0001] The invention relates to the technical field of gas supply, in particular to an intelligent gas mixing system. Background technique [0002] In the early days of gas low-temperature liquefaction storage, the use of gas compression storage was still used. Generally, a double-sided bus system with one backup and one use was used to achieve continuous and uninterrupted gas supply. Although low-temperature storage uses good thermal insulation materials, it will inevitably be affected by the ambient temperature, and natural evaporation will occur. Usually, the daily evaporation is about 5%. Although some back pressure valves can be used to recover, it is only suitable for small gas consumption from the gas phase port of the cryogenic storage tank. However, for large-scale applications, the gas source needs to be introduced from the liquid phase port of the cryogenic storage tank, and then vaporized by the vaporizer to increase the gas supply flow. However...

Problems solved by technology

[0004] The present invention provides an intelligent gas mixing system to solve the problem in the prior art that gas mixing is performed manually, and the required mixing dose cannot be accurately grasped, resulting in the presence of gases in the mixing device that cause the mixing ratio to be out of balance. Mixing again in the later stage, the problem of low accuracy of manual mixing
