Abstract

The invention relates to the field of municipal and industrial solid waste disposal and provides a heat exchange device for a sludge carbonization technology. The heat exchange device comprises a front heat exchange unit and a rear heat exchange unit; the front heat exchange unit comprises a plurality of front heat exchange groups which are connected in parallel and work alternately, and / or the rear heat exchange unit comprises a plurality of rear heat exchange groups which are connected in parallel and work alternately. When a material in certain heat exchange group is subjected to sufficient heat exchange, the other heat exchange groups can convey the material after the sufficient heat exchange to a subsequent device of a sludge hydrothermal carbonization system, so that the material can pass through the heat exchange groups stably and slowly, and undergoes sufficient heat exchange with heat exchange media in the heat exchange groups. In addition, the heat exchange groups work alternately, so that the heat exchange device can work continuously, and the heat exchange efficiency of the heat exchange device for the sludge carbonization technology is improved.

Description

technical field [0001] The invention relates to the field of municipal and industrial solid waste treatment, and provides a heat exchange device for sludge carbonization process. Background technique [0002] With the increase of urban population, industrialization, and the addition of urban sewage and wastewater treatment plants, the amount of sludge produced has gradually increased, and sludge treatment has become the focus of the environment. The drying, landfilling, composting and other processes of the original technology are only simple treatment of sludge. How to realize "reduction", "harmless" and "recycling" of sludge treatment has become the focus of many enterprises Focus in focus. Sludge carbonization technology is to "dry" the sludge under anaerobic or micro-aerobic conditions, so that the cells in the biochemical sludge are lysed, the water in it is released, and the carbon in the sludge is retained to the greatest extent. qualitative process. The sludge aft...
