A device and process for online renewal of turbulent ball tower packing

Abstract

This invention discloses a device for online replacement of packing material in turbulent ball towers, relating to the field of waste gas treatment technology. It includes multiple turbulent ball towers, an ultrasonic cleaning tank, and an integrated drying and screening machine. Pipes are installed at the ball-collecting ports of the multiple turbulent ball towers, connecting them to the ultrasonic cleaning tank. The integrated drying and screening machine is located behind the ultrasonic cleaning tank for drying and screening the cleaned turbulent balls. The design of multiple turbulent ball towers allows for the replacement of packing material in one tower while the others remain operational. When one flue gas pipe is closed, excess flue gas in the main pipe is carried by the other turbulent ball towers, thus maintaining stable operation of the entire device. This avoids throttling and channeling caused by large changes in operating conditions, enables online replacement of the turbulent ball tower packing material, and allows for the recycling of usable packing material, further reducing production and operating costs.

Description

Technical Field

[0001] This invention relates to the field of waste gas treatment technology, and in particular to an apparatus and process for online replacement of packing material in turbulent ball towers. Background Technology

[0002] The turbulent spherical packing tower consists of a support plate (grid), lightweight spheres, baffles, demisters, and other components. A certain amount of lightweight spherical packing is placed on the support plate (grid). Under the interaction of various forces such as the force of the rising high-speed airflow, the buoyancy of the liquid, and its own gravity, the spherical packing is suspended and forms turbulent rotation and collisions with each other, causing close contact between gas and liquid, effectively carrying out mass transfer, heat transfer, and dust removal. The turbulent spherical packing is made of hollow polypropylene spheres.

[0003] During the use of turbulent ball towers, the continuous collision of the turbulent ball packings causes partial wear and breakage of the hollow balls, greatly reducing the contact area between the spray liquid and the flue gas and lowering the absorption efficiency. Therefore, the turbulent ball towers are shut down periodically to replace the turbulent ball packings. However, shutdown and replacement not only affect production efficiency and increase operating costs, but also waste the original turbulent ball packings that can be reused. To address this, a device and process for online replacement and treatment of turbulent ball tower packings are proposed. Summary of the Invention

[0004] The purpose of this invention is to solve the problems in the prior art by proposing an apparatus and process for online replacement of packing in turbulent ball towers.

[0005] An apparatus for online replacement of packing material in turbulent ball towers includes multiple turbulent ball towers, an ultrasonic cleaning tank, and an integrated drying and screening machine. The ball-collecting ports of the multiple turbulent ball towers are connected to the ultrasonic cleaning tank via pipes. The integrated drying and screening machine is located behind the ultrasonic cleaning tank and is used to dry and screen the cleaned turbulent balls. The discharge port of the integrated drying and screening machine is connected to the ball-adding ports of the multiple turbulent ball towers via pipes.

[0006] Preferably, a vacuum pump is installed on the connecting pipe between the turbulent ball tower and the ultrasonic cleaning tank.

[0007] Preferably, each of the multiple turbulent sphere towers is provided with a flue gas pipe at its bottom, and the multiple flue gas pipes are connected to a main pipe.

[0008] Preferably, each of the flue gas pipes is equipped with a solenoid valve near the turbulent ball tower to control the flue gas entering the turbulent ball tower.

[0009] This invention also discloses a process for online replacement of packing material in turbulent spherical towers. The apparatus for online replacement of packing material in turbulent spherical towers includes the following steps:

[0010] S1. Close the solenoid valve on one flue gas pipe and remove the turbulent ball packing from the bottom support plate on the side of the turbulent ball tower using a vacuum method.

[0011] S2. After vacuum extraction, the small balls are put into the ultrasonic cleaning tank to quickly clean the turbulent ball packing and restore it to cleanliness.

[0012] S3. Take out the cleaned turbulent ball packing and add it to the drying and screening machine for drying and screening;

[0013] S4. Screen out and collect the turbulent ball packing that is not severely worn and meets the design requirements, and then put it back into the turbulent ball tower 1 for use.

[0014] Preferably, in step S3, waste heat gas at 90°C from the cement plant kiln head is introduced into the drying and screening machine to dry the turbulent ball packing.

[0015] Preferably, in step S4, the sieved turbulent ball packing needs to be replenished with new turbulent ball packing and then reinserted into the turbulent ball tower.

[0016] Compared with existing technologies, the advantages of this invention are:

[0017] The design of multiple turbulent ball towers in this invention allows the other turbulent ball towers to remain operational while one tower's packing is being replaced. After one flue gas pipe is closed, the excess flue gas in the main pipe will be carried by the other turbulent ball towers, thus maintaining stable operation of the entire device. This avoids slugging and channeling caused by large changes in operating conditions, enables online replacement of the turbulent ball tower packing, and allows for the recycling of usable turbulent ball packing, further reducing production and operating costs.

[0021] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0022] Reference Figure 1-2As shown, an apparatus for online replacement of packing material in turbulent ball towers includes multiple turbulent ball towers 1, an ultrasonic cleaning tank 2, and a drying and screening integrated machine 3. The ball-collecting ports of the multiple turbulent ball towers 1 are provided with pipes connected to the ultrasonic cleaning tank 2. The drying and screening integrated machine 3 is located behind the ultrasonic cleaning tank 2 and is used to dry and screen the cleaned turbulent balls. The discharge port of the drying and screening integrated machine 3 is provided with a pipe connected to the ball-adding ports of the multiple turbulent ball towers 1.

[0023] In this embodiment, a vacuum pump 4 is installed on the connecting pipe between the turbulent ball tower 1 and the ultrasonic cleaning tank 2. The vacuum pump 4 can be used to vacuum extract the turbulent balls in the turbulent ball tower 1, which can avoid manual operation and can also remove broken balls or residues and clear the sieve holes of the support plate that are blocked.

[0024] In this embodiment, each of the multiple turbulent sphere towers 1 is provided with a flue gas pipe 5 at its bottom, and the multiple flue gas pipes 5 are connected to a main pipe.

[0025] In this embodiment, each flue gas pipe 5 is equipped with a solenoid valve 6 near the turbulent ball tower 1 to control the flue gas entering the turbulent ball tower 1.

[0026] A process for online replacement of packing in turbulent ball towers includes the following steps:

[0027] S1. Close the solenoid valve 6 on one flue gas pipe 5. After the flue gas pipe 5 is closed, the excess flue gas in the main pipe will be carried by other turbulent ball towers 1. The turbulent ball packing in the turbulent ball tower 1 will be removed by vacuum from the bottom support plate on the side of the turbulent ball tower 1.

[0028] S2. After vacuum extraction, the small balls are placed into the ultrasonic cleaning tank 2 to quickly clean the turbulent ball packing and restore it to cleanliness.

[0029] S3. Take out the cleaned turbulent ball packing and add it to the drying and screening machine 3 for drying and screening.

[0030] S4. Screen out and collect the turbulent ball packing that is not severely worn and meets the design requirements, and then put it back into the turbulent ball tower 1 for use, so as to realize the recycling of usable turbulent ball packing and further reduce production and operating costs.

[0031] In step S3, waste heat gas at 90°C from the cement plant kiln head is introduced into the drying and screening integrated machine 3 to dry the turbulent ball packing.

[0032] In step S4, the sieved turbulent ball packing needs to be replenished with new turbulent ball packing and then reinserted into the turbulent ball tower 1.

[0033] The design of multiple turbulent ball towers 1 allows the other turbulent ball towers 1 to remain in operation while one of them is having its turbulent ball packing replaced. After one of the flue gas pipes 5 is closed, the excess flue gas in the main pipe will be carried by the other turbulent ball towers 1, thus maintaining the stable operation of the entire unit. This avoids slugging and channeling caused by large changes in operating conditions and enables online replacement of the turbulent ball tower packing.

[0034] As is known from common technical knowledge, this invention can be implemented through other embodiments that do not depart from its spirit or essential characteristics. Therefore, the disclosed embodiments described above are merely illustrative in all respects and are not the only ones. All modifications within the scope of this invention or its equivalents are included in this invention.
