Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of chemical gas collection and treatment, in particular to a chemical gas collection and treatment device for chemical industry. BACKGROUND

[0002] As an important pillar of the national economy, the chemical industry involves a large amount of chemical gas treatment in its production process. The collection and treatment of chemical gas not only relate to production efficiency, but also are closely related to the safety of operators and environmental protection.

[0003] However, the existing chemical gas collection and treatment device for chemical industry generally only sets a single storage tank. When the gas in the storage tank reaches saturation, it needs to be replaced after shutdown, which not only affects the continuity and efficiency of the production line, but also may cause safety hazards due to shutdown operation. Secondly, the existing device often lacks external protection for the storage tank. When the device is subjected to external impact, the storage tank is easily damaged, and even gas leakage occurs, which threatens the safety of operators and the environment. In addition, the storage tank is usually heavy, but the existing device lacks a convenient carrying and fixing mechanism, which consumes a lot of manpower and time when replacing the storage tank, and also increases the safety risk in the operation process.

[0004] For example, Chinese patent CN221958656U discloses a chemical gas collection and treatment device for chemical industry, which includes a collection box, a transfer tank, an air inlet pipe, a gas conveying pipe, a storage tank, a fixing pin, a movable frame, an electrochemical sensor, a first valve, an exhaust pipe, a box door and a display panel. The inside of the collection box is fixed with a transfer tank, and the upper end of the transfer tank is fixed with an air inlet pipe and a gas conveying pipe. The inside of the movable frame is fixed with a storage tank, and the storage tank is fixed with the gas conveying pipe. The inside of the movable frame is slidably provided with a fixing pin. The inner wall of the collection box is fixed with an electrochemical sensor, and the upper end of the collection box is fixed with an exhaust pipe, and the middle of the exhaust pipe is fixed with a first valve. The front side of the collection box is fixed with a box door, and the outer side of the box door is fixed with a display panel. The setting of the gas conveying pipe and the movable frame allows the storage tank to be taken out without shutdown operation, and the impact force can be buffered. At the same time, the storage tank can be easily moved to a designated position.

[0005] However, other gases may be mixed during gas collection, affecting the final quality. UTILITY MODEL CONTENTS
