The solution of negative pressure conveying of white carbon black is an efficient and environmentally friendly material conveying method, especially suitable for occasions with high environmental requirements. The following is a detailed plan for negative pressure delivery of white carbon black:

1、 Overview of the Plan

The negative pressure conveying white carbon black system utilizes the principle of negative pressure to suck white carbon black from the silo or storage device through pipelines and transport it to the designated receiving device. The entire transportation process is carried out in a closed pipeline, effectively preventing dust leakage and diffusion, ensuring a clean and hygienic working environment.

2、 System composition

1. Negative pressure sourceUsually, Roots vacuum pumps or other types of vacuum pumps are used as negative pressure sources to generate sufficient negative pressure for inhaling and transporting white carbon black.

2. Feeding deviceSuch as rotary airlock gas supply valve or vibrating feeder, used to quantitatively and uniformly add white carbon black into the conveying pipeline.

3. pipelineMade of wear-resistant and corrosion-resistant materials, ensuring that white carbon black does not react or wear against the inner wall of the pipeline during transportation. The pipeline layout should be reasonable, minimizing bends and resistance points as much as possible.

4. Receiving deviceSuch as cyclone separators, bag filters, etc., used to separate white carbon black from airflow and collect it. The receiving device should be designed reasonably to ensure separation efficiency and collection effectiveness.

5. control systemUsed to monitor and adjust various parameters during the conveying process, such as negative pressure magnitude, conveying speed, etc., to ensure the stability and reliability of the conveying process.

3、 Working principle

1. Start up phaseWhen the negative pressure pneumatic conveying system is started, the Roots vacuum pump starts working, generating negative pressure. At the same time, the feeding device began to quantitatively and uniformly add white carbon black into the conveying pipeline.

2. Transportation stageUnder the action of negative pressure, white carbon black is sucked into the pipeline and mixed with the airflow to form a gas-solid two-phase flow. The airflow drives the white carbon black to flow at high speed inside the pipeline and transport it to the receiving device.

3. Separation stageIn the receiving device, the airflow is separated from the white carbon black. White carbon black is collected for subsequent use or processing; And the airflow is discharged into the atmosphere or recycled after dust removal and other treatments.

   
   

4、 Advantages and Characteristics

1. Environmentally friendly and cleanThe entire transportation process is carried out in a closed pipeline, effectively preventing dust leakage and diffusion, ensuring a clean and hygienic working environment.

2. High conveying efficiencyThe negative pressure conveying method can fully utilize the energy of the airflow to promote the high-speed flow of white carbon black in the pipeline, improving the conveying efficiency.

3. Wide range of applicationsThe negative pressure conveying system is suitable for conveying white carbon black of various particle sizes and densities, and the conveying distance and height can be adjusted according to actual needs.

4. High degree of automationModern negative pressure conveying systems are usually equipped with advanced control systems and monitoring equipment, which can achieve automated operation and remote monitoring.

5、 Precautions

1. Equipment selectionWhen selecting equipment such as negative pressure sources, feeding devices, and conveying pipelines, reasonable selection should be made based on the characteristics and conveying needs of white carbon black.

2. Pipeline designThe pipeline layout should be reasonable, minimizing bends and resistance points to reduce transportation resistance; At the same time, the sealing and wear resistance of the pipeline should be ensured.

3. Dust removal measuresThe receiving device should be designed with reasonable dust removal measures to ensure separation efficiency and collection effectiveness; At the same time, the exhaust airflow should be treated with dust removal to prevent environmental pollution.

4. safety maintenanceRegularly conduct safety inspections and maintenance on the conveying system to ensure its normal operation and extend its service life.
