Oxygen split-filling busbar detection alarm device

Abstract

The invention relates to an oxygen split-filling busbar detection alarm device which comprises a liquid oxygen tank, a vaporizer and a busbar. A main electronic control valve is connected to a main tube in series, a plurality of branch electronic control valves are connected to branch tubes in series, a plurality of oxygen concentration sensors are arranged on the inner wall of a room where the busbar is located, a plurality of anti-explosion exhaust fans are further embedded on the inner wall of the room, the main electronic control valve, the branch electronic control valves, the oxygen concentration sensors and the anti-explosion exhaust fans are all connected with a central control module. According to the oxygen split-filling busbar detection alarm device, the main electronic control valves, the branch electronic control valves, the anti-explosion exhaust fans and the oxygen concentration sensors are arranged on the busbar, the oxygen concentration sensors are used for detecting concentration of oxygen in the environment and changing data and transmitting the data back to the central control module, the central control module starts the anti-explosion exhaust fans automatically once the concentration is too high so as to achieve indoor ventilation and outdoor ventilation, the local oxygen concentration is reduced quickly, and production safety is guaranteed greatly.

Description

technical field [0001] The invention belongs to the field of oxygenation equipment, in particular to a detection and alarm device for an oxygen dispensing busbar. Background technique [0002] Oxygen is a kind of combustion aid and oxidant, which is essential in industrial production. Its preparation method is: first liquefy the air, separate the oxygen, then convert the liquid oxygen into gaseous oxygen through a vaporizer, and finally pass it through the busbar. Multiple valves complete the subpackage of oxygen cylinders. During traditional packaging, the operator transports the empty oxygen cylinder to the room where the bus bar is located, and then connects the output end of the sub-valve installed on the bus bar to the interface on the upper end of the oxygen cylinder, opens the main valve and sub-valve, and the high-pressure oxygen automatically completes the oxygen supply. Filling and dispensing of the bottle, in the high-pressure oxygen delivery output from the abov...

Problems solved by technology

In traditional packaging, the operator transports the empty oxygen cylinder to the room where the bus bar is located, and then connects the output end of the sub-valve installed on the bus bar to the interface on the upper end of the oxygen cylinder, opens the main valve and sub-valve, and the high-pressure oxygen automatically completes the oxygen supply. Filling and dispensing of bottles, high-pressure oxygen delivery from the above-mentioned vaporizer, high-pressure oxygen pipes and busbars are equipped with main valves and sub-valves. These places are places where oxygen leaks. Once the local oxygen concentration is too high, it is easy to appear Explosion accidents affect production safety and are prone to casualties
