Problems solved by technology

[0002] Solid wastes such as municipal waste, industrial waste, municipal sludge, industrial sludge, biomass, medical solid waste, and hazardous solid waste have different sources and formation mechanisms. It is difficult to find common points in terms of geometric properties, etc., and it is not convenient for fine classification or centralized treatment and disposal; secondly, the accumulation angle of the above-mentioned solid waste and bulk materials is generally very small, and it is difficult to find common points in the storage, transfer, transportation, and advanced heat treatment process pretreatment of bulk materials. In the process of processing, there are often problems such as complex and diverse processing equipment, large footprint, low comprehensive processing efficiency, and limitations in the application of multiple systems.
[0003] When conventional incineration, gasification and other processes are directly used to treat solid waste, it is very easy to produce secondary pollutants or hazardous waste such as dioxin and fly ash due to the composition characteristics of solid waste materials and thermal reaction conditions. These secondary pollution The collection and treatment process of waste or hazardous waste is not only complicated, it is easy to cause more serious pollution, and the treatment cost is very high

Embodiment 1

[0031] Such as figure 1 , figure 2 As shown, a compression degassing carbonization device includes: a high-pressure compression device 1 , a material sealing chamber 2 and a degassing chamber 3 .

[0032] The high-pressure compression equipment, the material sealing chamber and the degassing chamber are sealed in sequence and installed on the same central axis. The high-pressure compression equipment is used for multi-stage, high-pressure, continuous compression molding of solid waste and bulk materials, as well as continuous discharge and material sealing. The chamber is filled with compressed solid waste material to form a natural isolation between the high-pressure compression equipment and the degassing chamber, so that the inlet of the degassing chamber is isolated from oxygen (air). The degassing chamber is used for drying, anaerobic pyrolysis and carbonization of solid waste blocks, and finally converts solid waste blocks into carbon powder and pyrolysis gas.

Abstract

The invention discloses a compression, degassing and carbonization method and device for solid waste, and a system comprising the device. According to the invention, irregular bulk materials such as municipal waste, industrial waste, municipal sludge, industrial sludge, biomass, medical solid waste and dangerous solid waste are continuously compressed and formed through multi-level high pressure; compressed solid waste blocks are dried, pyrolyzed and carbonized through anaerobic degassing, so carbon powder and pyrolysis gas are finally generated and can be used for pretreatment processes of incineration, gasification and other deep heat treatment processes of solid waste; and thus, the 'heat conversion efficiency of solid waste is improved, and deep reduction, recycling and harmless treatment are achieved.
