High moisture content organic matter carbonization or activation equipment and carbonization or activation process

Abstract

The invention discloses carbonization or activation equipment for organic matter with high water content and a carbonization or activation process. The equipment includes a swing-type rotary furnace; a feeding end of a roller of the swing-type rotary furnace the is higher than a discharge end; a drying segment, a destructive distillation segment and a carbonization segment are successively arranged in the roller; the outside of the roller is provided with a driving device and a supporting device, which are respectively used for driving and supporting the roller to conduct reciprocating swing around an axis; the driving device and a swing control device are connected by wires, and used for controlling actions of the driving device; the outer circumferential wall of the roller is provided with a heating device; the carbonization segment is provided with a gas introduction component for introducing gas containing oxygen; and a gas phase wall of the roller is provided with a pyrolysis gas outlet. Due to adoption of the swing-type rotary furnace, the heating device and gas introduction component can be arranged on the outer wall of the roller to ensure the heat treatment on each process by the roller. Compared with the existing rotary furnace, the equipment has simplified structure and process, is convenient for maintenance, and has low failure rate and improved service life. The application also discloses a carbonization or activation process.

Description

technical field [0001] The invention relates to the technical field of chemical equipment, in particular to a carbonization or activation equipment for organic matter with high water content. It also relates to a carbonization or activation process. Background technique [0002] Organic matter with high moisture content refers to chlorine-free straw, agricultural and forestry waste, sludge, manure, sorted organic waste, low-rank coal and their mixtures with a moisture content of 10% to 60%. Organic matter with high moisture content can produce carbon and activated carbon. One type of equipment currently used to produce charcoal and activated carbon is the rotary kiln. [0003] Existing rotary furnaces are usually composed of a drum, a furnace head and a furnace tail, wherein the furnace head and the furnace tail are fixedly rotated and sealed around the two ends of the drum, and are dynamically and statically sealed with the two ends of the drum, and the drum is driven by ...

AI Technical Summary

Problems solved by technology

Due to the continuous rotation of the drum, the material can only enter and exit at the furnace head and the furnace tail, and other pipes, heating components and sensors cannot be installed on the outer peripheral wall of the drum, resulting in the inability to effectively control the materials at various positions in the axial direction of the drum. Even if the control effect can be achieved, it can only enter the drum from the furnace head or tail, and the complicated pipeline is set inside the drum, the structure and process are very complicated, the maintenance is inconvenient, the failure rate is high, and the service life is short

In addition, since the furnace head and the furnace tail are sealed and connected around the two ends of the drum, the sealing surface between the two ends of the drum and the furnace head and the furnace tail is relatively large. Due to the thermal expansion and contraction of the furnace body and the limitation of high-temperature dynamic sealing materials for rotary furnaces working at high temperatures, the sealing effect is very poor, which has a great impact on the production process

[0004] To sum up, how to solve the problems of complex structure and process, inconvenient maintenance and high failure rate of the existing rotary kiln has become a problem to be solved urgently by those skilled in the art
