Abstract

The invention belongs to the technical field of biochar, and provides an integrated device for preparing biochar through co-pyrolysis of sludge and straw, which comprises a crushing device and a carbonizing device, the crushing device comprises a crushing bin, a feeding storage bin, a crushing mechanism and a first sieve plate; and the carbonizing device comprises a carbonizing bin and a stirringmechanism. According to the device, preparation steps and preparation equipment for preparing the biochar through sludge and straw heat supply are simplified, the time for connecting all procedures isshortened, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of biochar, in particular to an integrated device for co-pyrolyzing sludge and straw to prepare biochar. Background technique [0002] Sludge pyrolysis is an effective way to treat sludge. It is a chemical process in which sludge is heated under anaerobic or anoxic conditions to transform it into gaseous, liquid and solid products. It can greatly reduce the moisture and volume of sludge, making it easy to transport; degrade organic poisons to eliminate harmful bacteria and sludge odor; it can also effectively fix heavy metals, and also has the effect of adsorbing heavy metals in water and soil; greatly reduces sludge The pollution ability can achieve the effect of sludge resource utilization. [0003] However, because the sludge contains less organic matter and more volatile matter, moisture and heavy metals, the volatile analysis performance and solid product adsorption performance of sludge are poor when ...
