Description

Technical Field

[0001] The present invention relates to the technical field of waste gas treatment, and in particular to a device and process for online renewal of turbulent ball tower fillers. Background Art

[0002] The turbulent ball tower is composed of a support plate (grid), lightweight balls, a retaining net, a demister and other parts. A certain amount of lightweight spherical filler is placed on the support plate (grid). Under the interaction of various forces such as the impact of the rising high-speed airflow, the buoyancy of the liquid and its own gravity, the spherical filler is suspended to form turbulent rotation and mutual collision, causing close contact between gas and liquid, and effectively carrying out mass transfer, heat transfer and dust removal. The turbulent ball filler is polypropylene hollow balls.

[0003] During the use of the turbulent ball tower, the turbulent ball fillers constantly collide with each other, which will cause 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 tower is shut down regularly to replace the turbulent ball fillers. The shutdown for replacement not only affects the production efficiency and increases the operating cost, but also causes the waste of the original turbulent ball fillers that can be reused. Therefore, a device and process for online updating of turbulent ball tower fillers are proposed. Summary of the invention

[0004] The purpose of the present invention is to solve the problems in the prior art and to propose a device and process for online renewal of turbulent ball tower fillers.

[0005] A device for online renewal and processing of turbulent ball tower fillers includes multiple turbulent ball towers, an ultrasonic cleaning tank and a drying and screening integrated machine. The ball taking ports of the multiple turbulent ball towers are provided with pipelines connected to the ultrasonic cleaning tank. The drying and screening integrated machine is arranged behind the ultrasonic cleaning tank for drying and screening the cleaned turbulent balls. The discharge port of the drying and screening integrated machine is provided with pipelines connected to the ball adding ports of the multiple turbulent ball towers.

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

[0007] Preferably, a flue gas pipe is provided at the bottom of each of the plurality of turbulent ball towers, and the plurality of flue gas pipes are commonly connected to a main pipe.

[0008] Preferably, each of the flue gas pipes is provided with a solenoid valve near the turbulent ball tower for controlling the flue gas to enter the turbulent ball tower.

[0009] The present invention also discloses a process for online renewal of turbulent ball tower fillers, and the device for online renewal of turbulent ball tower fillers is used, comprising the following steps:

[0010] S1. Close the solenoid valve on a flue gas pipe and take out the turbulent ball filler in the turbulent ball tower from the bottom support plate on the side of the turbulent ball tower by vacuum;

[0011] S2. Put the vacuum-extracted balls into an ultrasonic cleaning tank to quickly clean the turbulent ball filler to restore it to cleanliness;

[0012] S3, taking out the cleaned turbulent ball filler and adding it into the drying and screening integrated machine for drying and screening;

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

[0015] Preferably, in step S4, the screened turbulent ball fillers need to be supplemented and mixed with new turbulent ball fillers and then placed back into the turbulent ball tower.

[0016] Compared with the prior art, the present invention has the following advantages:

[0017] The design of multiple turbulent ball towers in the present invention allows the turbulent ball filler of one of the turbulent ball towers to be replaced while the other turbulent ball towers are still in operation. After one of the flue gas pipes is closed, the excess flue gas in the main pipe will be carried by the other turbulent ball towers to carry the flue gas flow, thereby maintaining stable operation of the entire device, avoiding throttling and channeling caused by large changes in operating conditions, achieving online update processing of the turbulent ball tower filler, and recycling the available turbulent ball filler, further reducing production and operation costs.

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0022] Reference Figure 1-2As shown, a device for online renewal and processing of turbulent ball tower fillers includes multiple turbulent ball towers 1, an ultrasonic cleaning tank 2 and a drying and screening integrated machine 3. The ball taking 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 arranged at the rear of the ultrasonic cleaning tank 2 for drying and screening 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.

[0026] A process for online renewal of turbulent ball tower packing, comprising the following steps:

[0027] S1, close the solenoid valve 6 on a 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 to carry the flue gas flow, and the turbulent ball filler in the turbulent ball tower 1 is taken out from the bottom support plate at the side of the turbulent ball tower 1 by vacuum;

[0028] S2, putting the vacuum-extracted balls into the ultrasonic cleaning tank 2 to quickly clean the turbulent ball filler to restore it to cleanliness;

[0029] S3, taking out the cleaned turbulent ball filler and adding it into the drying and screening integrated machine 3 for drying and screening;

[0030] S4. The turbulent ball fillers that are not severely worn and meet the design requirements are screened out and collected, and then placed back into the turbulent ball tower 1 for use, so as to realize the recycling of the available turbulent ball fillers and further reduce the production and operation costs.

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

[0032] In step S4, the screened turbulent ball fillers need to be supplemented and mixed with new turbulent ball fillers and then placed back into the turbulent ball tower 1.

[0033] The design of multiple turbulent ball towers 1 allows the turbulent ball packing of one of the turbulent ball towers 1 to be replaced while the other turbulent ball towers 1 are still in operation. 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, thereby maintaining stable operation of the entire device, avoiding throttling and channeling caused by large changes in operating conditions, and realizing online update processing of the turbulent ball tower packing.
