Embodiment Construction

[0055] In order to make the above objects, features and advantages of the invention more obvious and understandable, the embodiments of the invention will be described in detail below in conjunction with the accompanying drawings.

[0056] refer to figure 1 , figure 1 It is a process flow chart of garbage preheating and drying based on the garbage preheating and drying device of the embodiment of the present invention.

[0057] From figure 1 It can be seen that in the garbage preheating and drying device of this embodiment, the furnace feeding system is basically composed of: the garbage material is sent to the push box 2 through the garbage grab 1 . The garbage materials entering the pusher box 2 are sent to the hydraulic pusher 6 through the chain plate machine 3, the feeder 4, and the belt conveyor 5 successively. Specifically, the untreated domestic waste is piled up, fermented and dehydrated in the waste warehouse, and then grabbed by the garbage grab 1 and put into th...

Abstract

The invention discloses a preheating and anhydration device for garbage. The preheating and anhydration device for the garbage is connected between a furnace feeding system of a circulating fluidizedbed garbage incinerator and a furnace. The preheating and anhydration device for the garbage comprises an anhydration screw conveyor. The anhydration screw conveyor comprises an anhydration wind chamber and a screw conveyor. The anhydration wind chamber comprises multiple hot air spouts. The screw conveyor is arranged on the anhydration wind chamber and used for scattering garbage materials, and drying is conducted under spiral driving through the anhydration wind chamber. A material outlet end is arranged in the anhydration screw conveyor. The material outlet end communicates with the furnaceof the circulating fluidized bed through a garbage blanking pipe. By means of the preheating and anhydration device for the garbage, coal consumption is lowered greatly; and emission of carbon monoxide is lowered by one order of magnitude.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a garbage preheating and drying device. Background technique [0002] In the existing circulating fluidized bed domestic waste incinerator, the domestic waste feeding equipment in front of the furnace is the core equipment for its fuel supply, which is used to send the waste into the furnace in a quantitative, safe and sealed manner for combustion. At present, the commonly used layout method: the untreated domestic garbage is piled up, fermented and dehydrated in the garbage warehouse, and then it is grabbed by the garbage grab and put into the hopper push box; the push box pushes the material down to the chain conveyor in a quantitative manner; the material It is transported to the front end of the chain plate, and then sent to the belt conveyor after the thickness of the material layer is limited by the dial machine. After manual large-scale sorting, it is tran...
