Vertical sludge drying, gasifying and incinerating integrated treatment device and method

Abstract

The invention provides a vertical sludge drying, gasifying and incinerating integrated treatment device and method. The device comprises an electronic control chamber, a feed mechanism, a drying chamber, a gasifying chamber, a combustion chamber for incinerating sludge, a crushing mixer-mill and a waste heat recovery mechanism. The drying chamber, the gasifying chamber and the combustion chamber are sequentially arranged from top to bottom. The waste heat recovery system can recover and use heat of the combustion chamber and the gasifying chamber, sludge gasified by the gasifying chamber and a small amount of pulverized coal are mixed and milled in the crushing mixer-mill and then enter the combustion chamber to be incinerated, and gas generated after gasifying is completed is exhausted through a combustible gas channel formed in the drying chamber. The vertical sludge drying, gasifying and incinerating integrated treatment device and method have the advantages of being integrated, compact in structure, environmentally friendly, high in gasifying efficiency and wide in application range, saving energy and the like, and is suitable for treatment of common domestic sludge and chemical engineering polluted sludge and similarly suitable for treatment of urban solid waste, and therefore the problems of energy shortage and environmental pollution control are effectively relieved.

Description

technical field [0001] The invention relates to the field of gasification, in particular to a vertical sludge drying and incineration integrated treatment device and method. Background technique [0002] With the rapid development of our country's economy, the problems of energy shortage and environmental pollution are becoming more and more serious. At the same time, urban life and chemical production will produce a large amount of sludge. How to treat and utilize sludge reasonably and effectively is of great significance for saving energy and protecting the environment, so this technology has also become a research focus of people today. At present, domestic sludge treatment methods mainly include landfill treatment, sludge gasification utilization, and direct incineration in sludge incinerators. [0003] The sludge landfill method has the advantages of simple operation and low investment, but the establishment of a sludge landfill requires a lot of waste of land resourc...

AI Technical Summary

Problems solved by technology

However, traditional gasifiers can only reasonably and effectively convert domestic sludge into renewable gas.

However, it cannot purify the combustible gas extracted from the gas; in addition, it cannot reasonably recycle the gasified sludge, and the waste heat emitted by the gasification chamber cannot be recovered, and the overall environmental protection is poor
