Description

Technical Field

[0001] The invention relates to the technical field of dust suppression and recovery equipment, and in particular to a petroleum coke blending dust suppression and recovery equipment. Background Art

[0002] In the process of blending petroleum coke, the generation of dust is an inherent challenge, which comes from multiple links such as crushing, screening and transportation of raw materials. These dusts will not only cause serious pollution to the working environment and affect the health of workers, but may also be mixed into the final product, reducing the quality and purity of petroleum coke, and further affecting the performance and application effect of downstream products. Therefore, effective dust suppression and recovery have become the key links to improve petroleum coke processing efficiency and product quality.

[0003] Traditional petroleum coke blending dust suppression and recovery equipment faces many challenges in dealing with dust problems. First, its core component, the filter plate, is easily clogged due to the rapid accumulation of dust during continuous operation, resulting in a sharp drop in filtration efficiency and unsatisfactory separation effect. This clogging not only limits the processing capacity of the equipment, but also increases maintenance costs and downtime, affecting the continuity and stability of the production line.

[0004] Secondly, the design of the power source of traditional equipment is often extensive and lacks consideration for energy saving and efficiency. Most equipment relies on direct motor drive, which has high energy consumption and low utilization rate. Especially when dealing with large amounts of dust, the energy consumption problem is particularly prominent, increasing the operating costs of enterprises.

[0005] Furthermore, when the filter plate is clogged, traditional equipment lacks an effective automatic response mechanism. The increase in gas pressure in the treatment box caused by the blockage may not only damage the equipment components, but also easily cause secondary release of dust when the sealed door is opened for maintenance, posing a threat to the environment and personnel health.

[0006] In addition, traditional equipment has obvious defects in cleaning the dust on the inner wall of the treatment box. Since the dust particles are small and light, they are easy to adhere to the inner wall of the treatment box, forming a deposit layer that is difficult to remove. This not only increases the difficulty of cleaning, but also during the cleaning process, the dust on the inner wall is easy to fall off and leak out with the airflow, further reducing the separation efficiency and environmental performance of the equipment. For this reason, we provide a petroleum coke blending dust suppression and recovery equipment. Summary of the invention
