Multi-class solid waste mixing and drying system

Abstract

The invention provides a multi-class solid waste mixing and drying system and belongs to the technical field of solid waste comprehensive treatment. The system comprises a plurality of solid waste temporary storage bins for respectively storing different types of solid waste, a layered fermentation stacking pool, a mixed biological drying pool and a transfer grab bucket. Different types of solid wastes are respectively temporarily stored in the solid waste temporary storage bins, are conveyed to the layered fermentation stacking pool by a solid waste conveying device, and are layered and stacked according to a certain stacking sequence and preliminarily fermented. The preliminarily fermented solid wastes are transferred into the mixed biological drying pool through the transfer grab bucket, fully mixed, and subjected to secondary biological drying. The practice proves that the mixed solid wastes after secondary biological drying have lower moisture content and more stable calorific value, can meet the long-time stable operation requirement of a solid waste gas gasification device, and simultaneously eliminates the low calorific value industrial solid wastes which are difficult to dispose.

Description

technical field [0001] The invention belongs to the technical field of solid waste comprehensive disposal, and in particular relates to a mixing and drying system for multi-category solid waste. Background technique [0002] Garbage gasification technology refers to the use of gasification method to gasify, melt and decompose the garbage at high temperature, and convert the organic components in the garbage into synthesis gas (mainly CO and H 2 ), and the inorganic matter is transformed into vitreous ash. Garbage gasification technology has the characteristics of high efficiency, safety, and no secondary pollution. The mainstream waste gasification technology includes thermal separation gasification technology and plasma gasification technology. In recent years, domestic scholars have made substantial research progress on many basic topics such as the characteristics of the flow field in the plasma reactor, the migration of harmful / usable elements, and the physical and che...
