Description

Technical Field

[0001] This utility model relates to the field of anode carbon block pipeline processing equipment, specifically a dust collection pipeline dust removal and detection device. Background Technology

[0002] In the preparation of anode carbon blocks, petroleum coke, one of the raw materials, needs to be calcined to obtain calcined petroleum coke to meet the requirements of anode carbon block production. For large-scale petroleum coke processing, calcination is performed in a calcining furnace at high temperatures. This process generates a large amount of smoke and dust, requiring centralized treatment through smoke and dust pipelines. However, during the flow and transport of the smoke and dust, its weight causes it to gradually accumulate at the bottom of the pipelines, leading to dust accumulation. Prolonged dust accumulation not only affects the normal flow and transport of the smoke and dust but also impacts the internal quality of the pipelines, causing corrosion of the inner walls. Therefore, the dust inside the pipelines needs to be treated. However, manual cleaning is difficult, and the pipelines need to be disassembled for easy cleaning, which necessitates the shutdown of the petroleum coke calcination operation, thus affecting the workshop's calcination processing.

[0003] Based on the above problems, there is a need to set up a dust collection pipeline dust removal and detection device that can facilitate the cleaning of dust from the inner wall of the dust collection pipeline, so that dust will not accumulate and block the pipeline, and no manual cleaning operation is required, in order to meet the processing and production needs of petroleum coke calcination. Utility Model Content

[0004] The purpose of this utility model is to provide a dust collection pipeline dust removal and testing device, which can facilitate the cleaning of dust on the inner wall of the dust collection pipeline, so that dust will not accumulate and block the pipeline. At the same time, it does not require manual cleaning by staff, thus meeting the processing and production needs of petroleum coke calcination.

[0005] To achieve the above objectives, this utility model employs the following technical solution:

[0006] A dust collection pipeline dust removal and detection device includes a blower assembly arranged in conjunction with the dust collection pipeline. Multiple blower assemblies are equally spaced on the outside of the dust collection pipeline, and the air inlet port of each blower assembly is connected to the dust collection pipeline. A fan-shaped blower nozzle is provided in conjunction with the air inlet port. The fan-shaped blower nozzle is inclined and its opening faces the lower end of the dust collection pipeline.

[0007] A gravity monitoring component is installed on the flue gas duct. The gravity monitoring component includes two gravity sensors, which are respectively installed at both ends of the flue gas duct to monitor the overall mass of the flue gas duct.

[0008] The gravity monitoring component and the blower component are connected via a control system for data feedback.

[0009] A dustproof screen is provided at the connection position between the fan-shaped blower nozzle and the air inlet port.

[0010] The blower assembly includes a blower and a conveying pipe. One blower is connected to multiple branch pipes of the conveying pipe, and each branch pipe is connected to the air inlet port on the dust and smoke pipe.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] This device is designed to prevent dust accumulation inside the flue gas duct by installing a blower assembly on the duct. The blower assembly directs gas flow into the duct, preventing dust buildup. Additionally, a fan-shaped blower nozzle is installed at the air inlet. This nozzle diffuses the gas in a fan shape to the bottom of the flue gas duct. If dust accumulation occurs, the blower assembly directs airflow into the duct, and the fan-shaped nozzle delivers high-velocity gas to the dust accumulation area at the bottom of the duct. This causes the dust to be stirred up and carried along with the flue gas exhaust, thus achieving dust removal within the flue gas duct. Attached Figure Description

[0018] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined in this application.

[0019] During the calcination of petroleum coke, a significant amount of smoke and dust is generated. This smoke and dust accumulates at the bottom of the smoke and dust pipe 1 as it is discharged, forming a dust layer. If this dust is not cleaned promptly, the accumulation inside the smoke and dust pipe 1 will increase, reducing its discharge capacity and eventually causing blockage. Furthermore, the smoke and dust produced during petroleum coke roasting consists of toxic particles. Manual cleaning requires disassembling the smoke and dust pipe 1, which disrupts normal calcination. Moreover, manual cleaning generates a large amount of dust that spreads throughout the plant, polluting the working environment and hindering the normal work of the staff.

[0020] A dust collection pipeline dust removal and detection device includes a blower assembly that is configured to work with a dust collection pipeline 1. Multiple blower assemblies are equally spaced on the outside of the dust collection pipeline 1, and the air inlet 2 of each blower assembly is connected to the dust collection pipeline 1. The blower assemblies can deliver high-velocity gas into the dust collection pipeline 1, allowing the high-velocity gas to directly act on the dust accumulation at the bottom of the dust collection pipeline 1. This causes the accumulated dust to be lifted up by the impact force, and the lifted dust then flows again with the gas discharged from the dust collection pipeline 1, thereby achieving the purpose of cleaning the accumulated dust. However, when high-velocity gas is conveyed into the dust duct 1 through the blower assembly, a key consideration is how to ensure that the high-velocity gas quickly and effectively acts directly on the dust accumulation area. Therefore, a fan-shaped blower nozzle 3 is installed in conjunction with the air inlet port 2. The fan-shaped blower nozzle 3 is inclined and its opening faces the lower end of the dust duct 1. Because most dust ducts 1 are tubular in shape, when dust accumulates at the bottom of the dust duct 1, the dust accumulation thickness is thicker at the center and gradually extends to both sides. Therefore, it is necessary to treat the center of the bottom of the dust duct 1 while also considering the cleaning of the thinner dust layer on both sides. The aforementioned fan-shaped blower nozzle 3 solves this problem. By setting the fan-shaped blower nozzle 3 to be inclined and its opening facing the lower end of the dust duct 1, the high-velocity gas passing through the fan-shaped blower nozzle 3 can diffuse outward in a fan shape, thereby acting on the dust accumulation layer inside the dust duct 1 and achieving comprehensive cleaning of the dust accumulation at the bottom of the dust duct 1.

[0021] Because dust accumulation in the flue gas duct 1 indicates that the duct cannot properly discharge dust, periodic monitoring by staff is necessary to determine if dust accumulation has occurred. Therefore, an automatic dust accumulation detection system is needed without constantly activating the blower assembly. Consequently, a gravity monitoring component 4 is installed on the flue gas duct 1. This component includes two gravity sensors 5, installed at both ends of the flue gas duct 1 to monitor its overall mass. The gravity monitoring component and the blower assembly are connected via a control system for data feedback. This gravity monitoring component monitors the overall mass of the flue gas duct 1. When the mass reaches a standard threshold, the blower assembly is activated to clean the dust accumulation within the flue gas duct 1 based on the data feedback between the gravity monitoring component and the blower assembly. It should be noted that the installation method of the gravity monitoring component, namely the gravity sensor 5, needs to be tailored to the construction method of the flue gas duct 1. If the flue gas duct 1 is installed by hoisting, the gravity sensor 5 needs to be installed at the hoisting connection point of the flue gas duct 1 to achieve the purpose of monitoring the overall quality of the flue gas duct 1. If the flue gas duct 1 is installed by laying, the gravity sensor 5 needs to be installed at the laying location of the flue gas duct 1. That is, it is necessary to ensure that the gravity sensor 5 is installed at the stress point of the flue gas duct 1 under the action of gravity to ensure that the gravity sensor 5 can effectively monitor the quality of the flue gas duct 1.

[0022] The above structure will be further configured and optimized:

[0023] A dustproof net 6 is provided at the connection position between the fan-shaped blower nozzle 3 and the air inlet port 2 to ensure that smoke and dust will not enter the blower assembly through the fan-shaped blower nozzle 3, so as not to affect the normal use of the blower assembly.

[0024] The blower assembly includes a blower and conveying pipes. One blower is connected to branch pipes of multiple conveying pipes, which are then connected to the air inlet ports 2 on the dust duct 1 to ensure the synchronicity of dust collection. However, it should be noted that dust collection should be carried out simultaneously with the calcination of petroleum coke, so that the blown-up dust can be discharged along with the exhaust gas, preventing the problem of dust accumulating again in the dust duct 1 after being blown out and left to stand for a period of time.

[0025] Therefore, a dust collection pipeline dust removal and testing device can conveniently clean the inner wall of the dust collection pipeline 1, so that dust will not accumulate and block the pipeline 1, and no manual cleaning operation is required, thus meeting the processing and production needs of petroleum coke calcination.
