Abstract

The invention relates to a closed blade stirring sludge drying system which comprises a blade stirring type sludge drying machine, a sludge inlet of the blade stirring type sludge drying machine is connected with a sludge conveying pump, and a carrier gas outlet of the blade stirring type sludge drying machine is connected with a washing tower. A gas outlet of the washing tower is connected with arecycling port of the blade stirring type sludge drying machine through an induced draft fan and a heater in sequence, and a sludge discharging port of the blade stirring type sludge drying machine is connected with dry sludge conveying equipment. The system is compact in structure, low in space occupancy, large in unit volume heat transfer area, high in drying speed and high in heat utilizationrate, and materials are uniformly stirred.

Description

technical field [0001] The invention relates to a drying system, in particular to a closed stirring sludge drying system. Background technique [0002] In recent years, with the continuous improvement of urbanization in our country and the improvement of environmental protection treatment facilities, a large amount of sludge is produced in the process of residents' lives and factory production. Especially municipal sewage sludge, drainage sludge from petroleum refineries, chemical plants, food factories, paper mills, drainage sludge from other industries, excrement and urine sludge and food waste, etc., the treatment cost is relatively high, and the treatment effect is average. . Contents of the invention [0003] Purpose of the invention: The purpose of the invention is to overcome the deficiencies in the prior art and provide a closed structure with compact structure, low space occupancy, large heat transfer area per unit volume, fast drying speed, uniform mixing of mat...
