Embodiment Construction

[0015] The following is an example of three-stage drying.

[0016] The first stage of drying is pressurized superheated steam drying in which wet materials are in direct contact with superheated steam.

[0017] Such as figure 1 As shown, the wet material is fed into the first-stage dryer 2 from the first-stage drying feed 1, and is heated and dehydrated by high-temperature superheated steam. The dried material is discharged from the drying system from the first-stage drying discharge 6. The steam produced by the evaporation of moisture in the wet material circulates in the first-stage drying system, passes through the first-stage drying cyclone dust collector 3, and the fine particle materials brought out are separated and discharged from the drying system by the first-stage drying cyclone discharge 7 . The dedusted gas passes through the first-stage drying and circulating fan 8 , enters the heat exchanger 5 and is heated by the high-temperature flue gas from the combustion...

Abstract

The invention relates to a reusable supercharging superheat steam drying method and a device which consists of a multi-stage drying system. The first stage drying is supercharging superheat steam drying, gas circulated in the system is superheat steam, wet materials are discharged out of the drying system after being heated and dehydrated by the superheat steam, the steam generated by moisture in the system is circulated in the system and provides heat to dry the wet materials after being heated by a heat exchanger. The superheat steam beyond the need of system circulation is discharged from the first stage drying to the next stage drying and is used as the heat source of the next stage drying. The second stage drying and each subsequent stage drying (except the last stage drying) are carried out by a supercharging indirect superheat steam drier with an internal heating device, which utilizes the superheat steam from the previous stage drying to dry the wet materials indirectly. The wet materials are discharged out of the drying system after being heated and dehydrated by the superheat steam, and the superheat steam from the previous stage drying is condensed into condensate water and then is discharged out of the drying system.

Description

Technical field [0001] The invention relates to a novel drying process with high efficiency and energy saving developed by reusing the steam produced by drying the superheated steam of the first stage in the second stage and subsequent stages of dryers. Background technique [0002] Superheated steam drying is a new type of environmental protection and energy saving drying technology. In superheated steam drying, the material to be dried is in direct contact with superheated steam. It has the advantages of energy saving, emission reduction, prevention of explosion and fire, and good quality of dried products. [0003] In the superheated steam drying process, the gas circulating in the system is superheated steam, in which the wet material is heated and dehydrated by the superheated steam to become steam, and the generated steam circulates in the system, and after being heated by a heat exchanger, it provides heat for Wet materials are dried. The superheated steam beyond t...
