A carbon black workshop in Weinan, Shaanxi, faces severe dust pollution and low material transport efficiency. The original dust removal system can no longer meet environmental protection and production needs. A company undertook a centralized dust removal and conveying renovation project for this workshop, aiming to optimize the environment and increase production capacity.

Customer pain points

During production, the carbon black workshop generates a large amount of ultrafine carbon black dust. The existing dust removal equipment lacks filtration efficiency, resulting in excessive emission concentrations and frequent environmental penalties. At the same time, manual cleaning and material transfer processes cause secondary dust pollution, threatening workers' health. In addition, workshops are compactly laid out, traditional conveying methods occupy large space and consume high energy, urgently requiring a centralized, automated integrated solution for dust removal and conveying.

Solution

To address these pain points, a company customized a centralized dust removal and conveying system. By using a high-efficiency pulse baghouse dust collector combined with a closed pneumatic conveying pipeline, it achieves a closed loop from dust collection to centralized treatment. The system is equipped with an intelligent control module that can monitor parameters such as pressure difference and airflow in real time, automatically adjusting the cleaning cycle to help maintain normal operation. The conveying process uses dense phase pneumatic conveying technology to reduce energy consumption, minimize pipeline wear, and support multi-point unloading, adapting to flexible workshop layouts. After the entire system was put into operation, emission concentrations remained stable below national limits, the workshop environment improved significantly, and material transfer efficiency increased by about 30%.
