AI Technical Summary

Technical Problem

Existing explosion-proof combustible gas mixing and distribution devices have low mixing efficiency and uneven gas concentration, which affects the stable operation of the compressor and the inconsistent filling quality of the gas cylinder.

Method used

The system employs a spiral-structured mixing pipe, compressed air storage tank, and combustible gas cylinder. Through a combination of pressure reducing valve, mass flow controller, and check valve, it ensures that the gas is mixed in a preset ratio. Furthermore, it utilizes a pressure buffer tank and diaphragm compressor to stabilize the gas pressure, thereby achieving efficient and uniform mixing.

Benefits of technology

It improves the uniformity and stability of gas mixing, ensures the normal operation of the compressor, and enhances the consistency of gas quality and the safety of the device.

Abstract

This utility model relates to the field of combustible gas mixing and distribution technology, and discloses an explosion-proof combustible gas mixing and distribution device, including a base plate. A compressed air storage tank, a combustible gas cylinder, and a pressure buffer tank are respectively arranged on the top of the base plate. The output ends of the compressed air storage tank and the combustible gas cylinder are respectively connected to a first exhaust pipe and a second exhaust pipe by bolts. The outer surface of the first exhaust pipe is respectively fixedly connected to a first pressure reducing valve, a first mass flow controller, and a first one-way valve. This device adopts a spiral structure mixing pipe, so that the compressed air and combustible gas form a spiral flow path in the pipe, prolonging the gas contact time. In conjunction with the process of compressed air and combustible gas being depressurized by the pressure reducing valve and precisely controlled by the mass flow controller, they enter the mixing pipe in an orderly manner through the one-way valve, effectively improving the mixing uniformity and solving the problems of low mixing efficiency and uneven concentration caused by the simple straight-through structure of existing devices.
