Benefits of technology

This patented method uses two stages of regenerating technology to improve the efficiency and effectiveness of treating harmful chemical pollutants (HCC) emitted through industrial processes such as coal burning or incinerations. By combining these techniques together, this new approach allows for better control over HC emission levels while reducing environmental concerns associated with current methods like catalyst regulation systems used on industries' facilities.

Problems solved by technology

This patented technical problem addressed by this patents relates to finding ways to dispose off harmful wastes from furniture products after they are painted with active carbon while also effectively removing any contaminating substances found on them.

Embodiment 1

[0030] 1. Regenerative processing unit

[0031] (1) Feed the waste honeycomb activated carbon into the vacuum chamber, the feed rate is 300kg / h, the vacuum chamber is made of anti-corrosion steel material, the working size is (1000*1000*600)mm, the thickness is 8mm to make a closed chamber with reinforcing ribs, There are two vacuum doors for entry and exit, and the opening and closing of the vacuum doors are completed by hydraulic cylinders. The seal adopts high temperature resistant rubber ring, and is equipped with vacuum pumping solenoid valve and nitrogen gas inlet solenoid valve. The evacuated gas is introduced into the secondary combustion chamber for harmless treatment. Vacuuming by a vacuum pump and introducing nitrogen as a replacement gas ensures an oxygen-free atmosphere during the thermal desorption process and ensures production safety. The intake volume of nitrogen gas is 5Nm 3 / h, the output of vacuum exhaust gas is 5Nm 3 / h. Vacuum exhaust gas passes into...

Abstract

The invention provides a waste honeycomb activated carbon regeneration process, and belongs to the technical field of waste treatment. The waste honeycomb activated carbon regeneration process solvesthe problems of resource waste and the like caused by direct incineration disposal of existing waste activated carbon, and comprises the following steps: S01, pyrolysis desorption: firstly preheatingthe waste honeycomb activated carbon, and then performing pyrolysis desorption at the temperature of 500-600 DEG C, S02, activation: at the temperature of 850-950 DEG C, by water vapor, conducting activation treatment on the activated carbon subjected to pyrolysis desorption in the step S01, and S03, cooling: cooling the activated carbon in the step S02 to obtain regenerated activated carbon, wherein the step S01, the step S02 and the step S03 are all carried out under the condition of vacuum oxygen deficit. The process can activate and regenerate the waste activated carbon.
