Solid hazardous waste cracking technology and complete equipment

Abstract

The invention belongs to the technical field of waste cracking, and particularly relates to a solid hazardous waste cracking technology and complete equipment. The equipment comprises a special cracking box for solid hazardous waste and intermittent cracking equipment, wherein the intermittent cracking equipment comprises an outer barrel and a rotatable inner barrel; at least one cracking materialplacement area is arranged in the inner barrel; the placement area is formed by a plurality of groups of guide plates circumferentially arranged on the inner wall of the inner barrel and baffles arranged on the tops of the guide plates at the two ends; each group of the guide plates comprise vertical plates and sieve plates that are alternately connected; and a reaction medium is arranged at thebottom of the inner barrel. By adopting the solid hazardous waste cracking complete equipment of the structure, the solid hazardous waste can be placed in the special cracking box for the solid hazardous waste; a box body is put between the baffles of the cracking material placement areas; after a cracking device is enclosed, heating can be performed for cracking; the inner barrel rotates to drivethe box body to rotate at the bottom of the inner barrel; and a material in the box body is heated and melted, and falls onto the reaction medium below; and the solid hazardous waste cracking is accomplished.

Description

technical field [0001] The invention belongs to the field of harmless treatment of hazardous solid waste, and in particular relates to a solid hazardous waste pyrolysis process and a complete set of equipment. Background technique [0002] Hazardous solid waste, also known as hazardous waste, toxic waste residue, etc., usually refers to solid waste with one or more hazardous characteristics such as toxicity, corrosiveness, flammability, reactivity, and infectivity. Hazardous waste comes from a wide variety of sources and is difficult to deal with. It not only pollutes air, water and soil, but also endangers human health and the environment through various channels. Hazardous solid waste can affect the environment in many ways, and its production, transportation, storage, treatment and disposal may cause major harm to the environment. Hazardous solid waste is the final state of many pollutants, which will remain in the environment for a long time. In order to control its po...

Problems solved by technology

[0003] The existing treatment methods generally include landfill method, incineration method, solidification method, chemical method and biological method. These methods can only achieve good results in a short period of time, but long-term use will still cause irreversible damage to the environment. At the same time, it is also a great waste of available resources in hazardous solid waste, so there is an urgent need for a safe and effective treatment method and process for hazardous solid waste to fill the gaps in the existing technology
