Roller drying system based on solar air heating

Abstract

The invention belongs to the technical field of new energy utilization devices, and relates to a roller drying system based on solar air heating. The roller drying system solves the technical problem that the design in the prior art is not reasonable enough. The roller drying system comprises a roller. The roller is connected with a driving device which can drive the roller to rotate, the feeding end of the roller is provided with a material conveying device which can convey materials into the roller. A solar heating device used for heating the roller is arranged outside the roller. One end of the roller is provided with a solar air heating device used for conveying hot air heated by the solar energy into the roller. The roller drying system has the advantages that the design is reasonable, the structure is simple, the clean energy is fully utilized, the natural resources are effectively protected, and the environment pollution can be avoided; the drying effect is good, the roller is heated uniformly, and the drying character requirement of dyeing sludge for the purpose of multifuel combustion can be fully met; the automation degree is high, operation and use are easy and convenient, implementation and industrial application are easy, energy is saved, and the roller drying system is economical, environmentally friendly, efficient and the like.

Description

technical field [0001] The invention belongs to the technical field of new energy utilization equipment, and relates to a dryer, in particular to a drum drying system based on solar air heating. Background technique [0002] Printing and dyeing sludge is mostly dried by consuming energy such as electricity, coal or natural gas. Sludge drying is a process of net energy expenditure, and the drying cost is relatively high. Under the background of advocating energy conservation, emission reduction, and protection of resources and the environment, countries are actively using new energy technologies in this field to save conventional energy consumption, reduce carbon dioxide emissions, and achieve the purpose of ecological development. [0003] In order to improve the drying effect and save energy, people have carried out long-term exploration and proposed various solutions. For example, Chinese patent literature discloses a printing and dyeing sludge drying treatment system [ap...
