Problems solved by technology

This technology uses cold air as the combustion-supporting air, water quenching and slag removal, and thermal pipes introduced into the calciner to dissipate heat, which reduces the heat utilization efficiency of the system. The solid waste is dried on the surface of the grate furnace, and the fire needs to rely on the primary air and flame combustion. The combustion of heat and solid waste is only carried out in a limited shallow space, and it needs to rely on a longer residence time to achieve burnout

Abstract

The invention provides an inclined rotary combustion device for efficiently disposing solid waste, and relates to the technical field of solid waste disposal. The inclined rotary combustion device for efficiently disposing the solid waste comprises a rotary furnace (1), a mixed feeding chamber (2), a feeding machine (3), a decomposing furnace (4) and a tertiary air main pipe (6), wherein the tail of the rotary furnace (1) is connected with the mixed feeding chamber (2), and the head of the rotary furnace (1) is connected with the decomposing furnace (4); the feeding machine (3) is arranged at the top of the mixed feeding chamber (2); the rotary furnace (1) comprises a rotary furnace cylinder (101), a supporting wheel device (102), a cold air sleeve (105), an iron protection plate (106) and a material return box (110); and slope-shaped structures (5) are arranged between the rotary furnace (1) and the mixed feeding chamber (2) and between the rotary furnace (1) and the decomposing furnace (4) for transition, and sealing structures are arranged correspondingly. The inclined rotary combustion device is stable and reliable in operation, low in operation cost, high in solid waste disposal adaptability, high in burn-off rate and capable of avoiding secondary pollution.

Description

technical field [0001] The invention relates to the technical field of solid waste disposal, in particular to an inclined rotary combustion device for efficiently disposing of solid waste. Background technique [0002] When industrial kilns are used to incinerate solid waste and domestic waste, in order to solve the problem that such multi-phase solid waste cannot be burned stably, there are usually restrictive requirements on the calorific value of the materials entering the furnace, and the drying, ignition, combustion, and burnout Targeted equipment structure development should be carried out in the area to ensure the effect of incineration disposal. Currently commonly used solid waste incineration disposal devices mainly include the following types: [0003] (1) Mechano-biological method + decomposition furnace: The combustible components in the solid waste are dehydrated and sorted by the mechanical-biological method, and then enriched and prepared into Refuse Derived ...
