Description

Technical Field

[0001] The utility model relates to the technical field of gas detection equipment, in particular to a gas detection and purification integrated system. Background Art

[0002] The main function of the integrated gas detection and purification system is to combine the functions of the gas detector and the gas purifier to achieve rapid and accurate detection of the concentration of harmful gases in the environment. Harmful gases mostly refer to carbon monoxide, sulfur dioxide and nitrogen oxides, etc., and remove harmful gas components and impurities at the same time to provide a clean and reliable gas source;

[0003] During the use of the gas detection and purification system, the detection equipment is usually used to detect the content of harmful gases in the air. When the content of harmful gases in the air is higher than the set value, the gas detection and purification system increases the flow rate of the air through the exhaust equipment, and then sprays the absorbent through the nozzle to absorb the harmful gases and impurities in the air;

[0004] During operation, the existing integrated gas detection and purification systems can absorb harmful gases and impurities in the air by spraying absorbents through nozzles, but the positions of the nozzles are mostly fixed and their spraying area is limited. In order to ensure the purification effect of harmful gases, some integrated gas detection and purification systems usually have multiple groups of nozzles that spray absorbents at the same time to purify harmful gases. Although this method increases the spraying area of ​​the nozzles, it also makes the internal structure of the integrated gas detection and purification system more complicated. For this reason, we propose a integrated gas detection and purification system. Utility Model Content
