Drying device and system

Abstract

The invention relates to a drying device and system. The drying device comprises a cold and heat source, a heating box, a condensing box and a condensate water return device. The heating box is arranged in the condensing box, a heating jacket and a condensing jacket are correspondingly arranged on the outer wall of the heating box and the outer wall of the condensing box correspondingly, cold water and hot water generated by the cold and heat source communicate with the condensing jacket and the heating jacket through conveying pipelines correspondingly, the upper end of the heating box is open, materials to be heated are contained in the heating box, and the condensate water return device communicates with the condensing box. Cold water and hot water generated by the cold and heat source are supplied to the jacket of the condensing box and the jacket of the heating box correspondingly, then materials in the heating box are heated, steam generated in the heating process overflows from the upper end of the heating box, is condensed and dripped after encountering the inner wall of the condensing box and then is discharged to the condensate water return device, so that water in the heating box is rapidly boiled and condensed, the whole device is in high drying efficiency, and therefore the dewatering efficiency is improved, meanwhile, the structure is simple, and the whole device is efficient and energy-saving.

Description

technical field [0001] The invention relates to the technical field of drying, in particular to a drying device and system. Background technique [0002] With the development of industries such as automobiles and home appliances, there are more and more industrial wastes, especially the proper disposal of paint residues and the reduction and utilization of paint residues are imminent. At present, various automobile manufacturers need to dry the paint slag before sending it to the chemical plant to reduce the weight of the paint slag, thereby reducing the cost of paint slag treatment. [0003] In the prior art, the drying equipment involving industrial waste usually directly uses high-temperature steam as the drying source, the equipment processing efficiency is low, and the overall drying and dehydration efficiency of the drying equipment is low. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a drying device an...
