Drying structure, drying device and drying method

Abstract

The invention relates to a drying structure, a drying device and a drying method, the drying structure comprises at least two mesh plates and a drying layer arranged between the mesh plates, and at least one layer of gap is arranged between the adjacent mesh plates. Correspondingly, the invention further provides a drying device, and the drying device comprises a frame structure used for storing the drying structure and ventilation equipment capable of storing the frame structure. The drying device is arranged, the gaps are formed between the adjacent mesh plates, it can be guaranteed that air can penetrate through the gaps to enter the fiber structures covering the mud raw materials, then the air drying speed is increased, the fiber structures and the mesh plates are arranged in the drying device in a layer-by-layer stacking mode, and the drying efficiency is improved. And the drying device with the drying structure is moved to the ventilation equipment, so that the sludge raw material can reach an extremely high dehydration rate in unit time, the sludge drying amount is increased, the power consumption per kilogram is reduced, and the advantages of low energy consumption cost and high dehydration efficiency are achieved.

Description

technical field [0001] The invention relates to the technical field of environmental protection equipment, in particular to a drying structure, a drying device and a drying method. Background technique [0002] At present, under the influence of global warming, the discharge of industrial and agricultural wastewater has caused eutrophication in lakes, reservoirs and other water bodies, which provides favorable conditions for the reproduction of blue-green algae, resulting in large-scale outbreaks of blue-green algae, which have become indispensable for water sources such as lakes and reservoirs. neglected issues. [0003] At present, the drying of algae sludge or sludge is mainly realized by heat treatment process, specifically, the water in the sludge is evaporated through heating equipment, but the traditional drying equipment is bulky and requires a long drying time, and even Some drying equipment also has the problem of poor dehydration effect. If the dehydration effect...

Problems solved by technology

[0003] At present, the drying of algae sludge or sludge is mainly realized through heat treatment process, specifically, the water in the sludge is evaporated through heating equipment, but the traditional drying equipment is bulky and requires a long drying time, even Some drying equipment also has the problem of poor dehydration effect. If the dehydration effect is not good, after the algae sludge or sludge containing water is piled up in the yard, affected by the high temperature in summer and the open environment, the cyanobacteria or sludge will Perishable and smelly, seriously affecting the surrounding air quality and environment

In addition, the existing drying equipment still has the problems of high energy consumption and high energy consumption costs.
