Drying device utilizing biomass gas for heating

Abstract

The invention provides a drying device utilizing biomass gas for heating. The drying device comprises a rotary device, a shell and a heating assembly, wherein the rotary device comprises a rotary kiln, the shell is asymmetrically arranged on the outer side of the rotary kiln and partially is arranged on the rotary kiln in a sleeving mode, a heating cavity is formed between the outer wall of the rotary kiln and the inner wall of the shell, the shell is sequentially divided into a combustion area, a temperature adjusting area and a heat preservation area in the axial direction of the rotary kiln, the rotary kiln is provided with a combustion area kiln section, a temperature adjusting area kiln section and a heat preservation area kiln section which correspond in sequence, and the heating assembly comprises a plurality of fire spraying heads. Through the above arrangement, the drying device carries out staged drying on a to-be-dried object through the heating assembly, the to-be-dried object can be rapidly and controllably dried by using the high temperature in the combustion area, and meanwhile, the damage to the to-be-dried object is reduced, and the pot sticking phenomenon is prevented from occurring; and the to-be-dried object is further dried in the later two sections of temperature areas, the humidity of the to-be-dried object can be further reduced, and meanwhile, the temperature of the to-be-dried object is low so as to avoid performance changes generated when the to-be-dried object makes contact with air.

Description

technical field [0001] The invention relates to the technical field of drying, in particular to a drying device heated by biomass gas. Background technique [0002] The drying device in the prior art generally adopts one-time drying, that is, the object to be dried is completely passed into the drying device for heating. Such a design cannot monitor the drying situation during drying, resulting in Waste of resources during drying. At the same time, due to the one-stage drying, the drying degree cannot be adjusted according to the state during drying, which is easy to damage the physical properties of the to-be-dried object, and the temperature of the to-be-dried object after continuous drying It is relatively high, and it needs to be heat-dissipated before it can continue to be used. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. Therefore, an object of the present invention is to p...
