Description

Technical Field

[0001] This utility model relates to the field of deep purification treatment of waste gas, and in particular to a device for deep purification treatment of waste gas. Background Technology

[0002] Advanced waste gas purification systems are key equipment in industrial production used for the deep treatment of emitted waste gases. Their core function is to remove harmful components such as dust, toxic gases, and volatile organic compounds from waste gases through multiple purification processes, ensuring that the treated waste gas meets national or local emission standards. This reduces environmental pollution and protects the ecological environment and human health. These systems are widely used in various industries that generate waste gases, such as chemical, coating, printing, and electronics, and are an important guarantee for achieving compliant industrial waste gas emissions.

[0003] Common equipment related to deep waste gas purification includes wet scrubbing equipment, whose typical structure usually includes a tower, a spray system, a circulating water tank, and a water pump. The tower is the main space for waste gas treatment, with waste gas entering from the bottom. The spray system, installed inside the tower, consists of spray pipes and nozzles. The circulating water tank, located below the tower, stores the scrubbing liquid (usually water or a solution with added purifying agents). The water pump connects the circulating water tank and the spray system. Its working principle is as follows: the water pump delivers the scrubbing liquid from the circulating water tank to the spray system, where it is atomized and sprayed onto the tower through the nozzles, making full contact with the rising waste gas. The scrubbing liquid absorbs, dissolves, or neutralizes harmful components in the waste gas. After purification, the scrubbing liquid flows back to the circulating water tank under gravity for recycling, and the purified waste gas is discharged from the top of the tower.

[0004] In the operation of existing wet scrubbing equipment, the liquid level control of the circulating water tank is a crucial factor affecting the stable operation of the equipment. Due to factors such as moisture introduced by the exhaust gas, evaporation of the spray liquid, and fluctuations in the amount of replenishing liquid, abnormal liquid levels often occur in the circulating water tank. When the liquid level in the circulating water tank is too high, the spray liquid will overflow directly from the tank, resulting in waste of the spray liquid and pollution of the surrounding environment. When the liquid level in the circulating water tank is too low, the tank will be emptied. At this time, the water pump cannot obtain enough spray liquid at the suction end, causing the water pump to run dry. Under dry running conditions, the internal components of the water pump will overheat and burn out in a short time due to lack of lubrication and cooling, seriously affecting the normal operation of the equipment, increasing equipment maintenance costs and downtime. Therefore, a deep exhaust gas purification treatment device is proposed to solve the above problems. Summary of the Invention

[0005] To overcome the above deficiencies, this utility model provides a deep purification treatment device for exhaust gas, which aims to improve the problem of water pump running dry or burning out due to overflow or cavitation of the circulating water tank in the prior art.

[0036] Working principle: When the water level in the tower body 1 is lower than the set safe water level, the water level in the circulating water tank 8 drops synchronously. At this time, the float ball 14 also drops with the water level, and the connecting rod 15 rotates along the fixed shaft 16, moving the slider 17 backward to separate it from the inner tube 18. This allows water in the inner tube 18 to enter the circulating water tank 8 through the outlet on the outer tube 19. At this time, the water level rises. As the water level rises, the float ball 14 floats up and drives the connecting rod 15 to rotate in the opposite direction, pushing the slider 17 to re-fit with the inner tube 18. Then, the water intake stops, achieving the purpose of automatic water level adjustment and control. This ensures the stability of the water level in the circulating water tank 8 and the operational stability of the equipment, solving the problem of water overflow or cavitation in the circulating water tank 8. The problem of pump running dry or burning out; during the process of opening the inspection window 5, first press button 20, spring 1 24 is compressed, chuck 23 rotates around shaft 22, the protrusion at the top of chuck 23 then leaves the groove on the locking block 27, and the connecting block 26 pushes the locking block 27 out under the reaction force of spring 25, thereby opening the inspection window 5 for internal maintenance work of tower body 1. After the maintenance is completed, push the inspection window 5 back into place, and chuck 23 re-engages with locking block 27 under the reaction force of spring 1 24, thus fixing the inspection window 5 and achieving the purpose of quick opening and closing of the inspection window 5, reducing the difficulty and time of maintenance, and solving the problem of inconvenience in removing flanges or entering the tower when there is no inspection port.
