Embodiment 1

[0012] Example 1: The solid waste collected by the garbage power plant is shoveled by a forklift onto the vibrating mesh screen in the upper part of the feeding bin, and the materials are manually sorted and roughly selected. During the sorting process, large metal objects and The combustibles are separated and concentrated, and the large solid wastes are knocked open with a hammer so that the solid wastes can pass through the sieve holes of the mesh screen. The material that enters the feeding bin through the sieve hole of the vibrating screen is sent to the drum sieve through the conveyor. The diameter of the sieve hole of the drum sieve is 5cm, and the particles larger than 5cm are filtered out by the drum sieve and crushed by the jaw crusher to remove combustible materials. After the material enters the drum sieve, the small particle materials passing through the drum sieve are carried by the conveyor and sent to the storage bin. The electromagnetic adsorption machine is re...

Embodiment 2

[0013] Embodiment 2: The water-type separation process includes water-type crushing, wet-type adsorption and vibration separation, and the small particle materials in the storage bin are sent to the water-type crusher ① and Water-type crusher ②, add water to crush the sand and metal, and send it to jig ① and jigger ② through the U-shaped groove installed between the water-type crusher and jig machine to separate the non-magnetic metal and sand. Soil separation, the metal settles under the jig machine, the sand enters the drum fine screen with the water flow, and the light and fine metal, fibers and other sundries are separated from the sand by the drum fine screen, and the sand under the drum fine screen The soil is sent into the sand dredger and the dehydrator through the U-shaped groove installed between the fine screen of the drum and the dewatering device to become building materials with moderate water content; the sundries on the fine screen of the drum are introduced int...

Abstract

The invention discloses a regeneration process for solid waste of garbage power plants. According to the regeneration process, combustible materials, metal and sand in the solid waste are separated. A separation process comprises a dry separation process and a wet separation process; facilities related to the dry separation process comprise a vibrating mesh screen, a feeding bin, a conveyor, a cylinder screen, a jaw crusher, a material storage bin, an electromagnetic absorption machine and a wet type cylinder magnetic separator. Materials are subjected to coarse separation through dry type breaking and electromagnetic adsorption and then subjected to the wet separation process. The facilities related to the wet separation process comprise a wet type crusher, a U-shaped groove, a washbox, a cylinder fine screen, a water filtering screen, a shaking table, a bailing machine, a water extractor, a sand pool and a water pool. The materials are subjected to fine separation through the wet separation process, and finally the waste solid materials are divided into the combustible materials, metal and sand; the combustible materials are sent back to a combustion furnace to burn, the metal is regenerated and utilized after being classified, and the sand is used for manufacturing wall bricks and/or other construction materials.

Description

technical field [0001] The invention relates to a recycling process for solid waste in a waste-to-energy plant, in particular to a regeneration process for solid waste that cannot be burned by a combustion furnace in a waste-to-energy plant, and belongs to the technical field of resource recovery. Background technique [0002] The fuel of the waste-to-energy plant is municipal solid waste plus a certain proportion of coal. Municipal solid waste contains a wide variety of items, including a large number of plastic bags, fiber fabrics, black gold, non-ferrous metals, etc., which also contain a considerable proportion of sand and soil. Generally can burn under the ignition. However, the combustibles wrapped in sand cannot be burned because of the isolation layer, and the incombustible items, including metals and sand, are cleaned out of the furnace and become solid waste. A waste-to-energy plant in a relatively developed county-level city produces 1 to 2 million tons of such ...
