Description

Technical Field

[0001] This utility model relates to the field of waste gas purification tower technology, and in particular to a circulating spray type industrial waste gas purification tower. Background Technology

[0002] A circulating spray industrial waste gas purification tower is a device used to treat industrial waste gas. It achieves purification by bringing pollutants in the waste gas into contact with a liquid through a spray system. The spray liquid is usually water or a solution containing chemicals. When the waste gas comes into contact with the spray liquid, the pollutants are adsorbed or dissolved by the liquid. Through the contact between the spray system and the waste gas, harmful substances in the waste gas are effectively removed. It can treat different types of waste gas, including various industrial waste gases containing dust, acids, alkalis, etc.

[0003] The industrial waste gas purification spray tower disclosed in announcement number CN206935057U uses a cylindrical vertical spray tower body with a conical head at the top. An air inlet is welded to the lower part of the tower body, an observation window is welded to the upper part, and an air outlet is welded to the top of the head. A circulating water tank with return water holes is welded to the bottom side of the cylindrical vertical spray tower body. Two to six layers of agitator impellers are installed in the inner middle of the cylindrical vertical spray tower body, and spray pipes are installed at the top of the tower. A submersible pump is fixedly installed in the circulating water tank on the outer side of the bottom, and the submersible pump is connected to the spray pipes through a connected water pipe. Its structure is simple and practical, with good waste gas purification effect, and the spray water is recycled, making it suitable for primary purification treatment of industrial waste gas.

[0004] However, existing circulating spray industrial waste gas purification towers have the following disadvantages: the traditional packing layer disassembly requires complex operations, which increases downtime for maintenance and reduces efficiency. Utility Model Content

[0015] As a further embodiment of this utility model, a pull plate is fixedly connected to one side of the sealing frame, and a handle is fixedly connected to one side of the fixing frame.

[0016] (III) Beneficial Effects

[0017] This utility model provides a circulating spray type industrial waste gas purification tower, which has the following beneficial effects:

[0018] 1. This circulating spray-type industrial waste gas purification tower, through the setting of sealing components and fixed frames, allows for convenient replacement or maintenance of the packing material. First, the pull plate is pressed down, causing the sealing frame to disengage from the slot within the purification tower body. Then, the fixed frame is pulled, allowing it to slide within the purification tower body. The slider slides out within the groove, and the fixed frame is then lifted for replacement using a suspension hook and crane. During installation, the fixed frame is inserted into the purification tower body, where the support spring contracts under pressure. When fully inserted, the support spring pushes the sealing frame into place, achieving convenient packing material replacement. This avoids the complex operations required for traditional packing layer disassembly, significantly shortens downtime for maintenance, and effectively prevents gas leakage.

[0019] 2. This circulating spray-type industrial waste gas purification tower, through the design of its cleaning components and filter boxes, allows waste gas to enter through the inlet pipe and then into liquid water at the bottom of the filter box. The water level is higher than the bottom of the baffle, causing the waste gas to combine with the water and promoting the deposition of dust particles and other substances. When the deposited impurities reach the bottom of the filter box, the drive motor is activated, causing the threaded rod to rotate and thus moving the moving frame. The telescopic spring presses the push plate tightly against the bottom surface, pushing the deposits to the treatment port on one side of the filter box for easy and unified processing. This prevents dust particles and other substances from entering the main body of the purification tower and causing blockage of the packing. Through graded purification, the equipment achieves long-term stable operation while reducing the workload of manual cleaning. Attached Figure Description

[0036] Second step: When in use, exhaust gas enters through the intake pipe 17 and enters the liquid water at the bottom of the filter box 5. The water level is higher than the bottom of the baffle 6, which causes the exhaust gas to combine with the water, promoting the deposition of dust particles and other substances. When the deposited impurities are at the bottom of the filter box 5.

[0037] The third step: Start the drive motor 13, which drives the threaded rod 7 to rotate, thereby moving the movable frame 801. The telescopic spring 802 presses the push plate 803 tightly against the bottom surface, and the push plate 803 pushes the sediment to the treatment port on one side of the filter box 5 for easy unified processing by personnel.
