Carbon black, also known as carbon black, is a light, loose and very fine black powder. Carbon black has a reinforcing effect on rubber, so it is one of the indispensable raw materials in the rubber industry. In addition, carbon black can also be used as a black dye for the manufacture of Chinese ink, ink, paint, etc.
As one of the common raw materials in industrial production, carbon black has been widely used, but it has been listed as one of the 2B carcinogens since 2017. Therefore, contact with operators should be avoided as much as possible during the production process. In this regard, the use of positive pressure dense phase pneumatic conveying system for carbon black conveying and production has great advantages.
1. Characteristics of carbon black positive pressure dense phase pneumatic conveying system
The biggest difference between the carbon black positive pressure dense phase pneumatic conveying system and the negative pressure pneumatic conveying system and the positive pressure dilute phase pneumatic conveying system is that the compressed air is used in the conveying pipeline. In addition, a bypass air intake pipe is added, which can input compressed air from the bypass pipe when there is a blockage in the conveying pipe, and the compressed air enters the conveying pipe to cut the carbon black into short plugs, so as to achieve normal conveyance and eliminate blockages.
2. Advantages of carbon black positive pressure dense phase pneumatic conveying system
The positive pressure dense phase pneumatic conveying system is suitable for conveying from one place to many places. At the same time, compressed air is used for conveying, which consumes less air. Therefore, when the carbon black is discharged from the discharge port, only a relatively simple separator is required. , without the need for a large separator.
The air with high humidity will have impurities such as oil stains and rust after being pressurized. Generally, a cooler and a dryer need to be installed to eliminate the influence of impurities, but on the other hand, this will cause a large pressure loss to the fan. The dense phase wind conveying uses compressed air as the power, and the air obtained by entering the compressor is clean and dry, and will not affect the quality of carbon black.
