Embodiment 1

[0035] see figure 2 As shown, this embodiment provides an MVR belt drying system, which is especially suitable for drying paste materials, but is not limited to the drying of paste materials. Specifically, the MVR belt drying system of this embodiment includes: a belt dryer DG and a material inlet and outlet unit connected to the belt dryer DG, an MVR circulation unit CY-1, a steam recirculation unit CY-2 and a waste heat recovery cycle Unit CY-3.

[0036] The feeding and discharging unit includes a feeding part that is respectively connected with the belt dryer DG and is suitable for pre-processing the wet material M1 before entering the belt dryer DG, and is suitable for processing the dry material M1 after being processed by the belt dryer DG. The output part of M2 for post-processing. Wherein, the feed part includes a preheater H1 suitable for preheating the wet material M1; the discharge part includes a heat exchange device suitable for the dry material M2 processed by...

Embodiment 2

[0045] On the basis of the MVR belt drying system in Example 1, this embodiment provides a MVR belt drying method, using the MVR belt drying system in Example 1, specifically including:

[0046] Step S1: the belt dryer DG dries the wet material M1;

[0047] Step S2: MVR circulation unit CY-1 recompresses part of the secondary steam generated by the belt dryer DG to form compressed steam and then enters the heating chamber of the belt dryer DG for recycling;

[0048] Step S3: The steam recirculation unit CY-2 recirculates part of the secondary steam generated by the belt dryer DG and then enters the drying chamber of the belt dryer DG for recycling;

[0049] Step S4: The waste heat recovery cycle unit CY-3 performs preheat recovery on the high-temperature liquid condensed water condensed and phase-transformed in the heating chamber of the belt dryer DG and recovers the cooling heat of the dry material M2 dried by the belt dryer DG for reuse.

[0050] It should be noted that t...

The system comprises a band dryer and further comprises a feeding and discharging unit, an MVR circulating unit, a steamrecycling unit and a waste heat recycling circulating unit which are connected with the band dryer. The MVR band drying system and the drying method thereof can improve the heat transfer process of the drying process so as to enhance stability and safety of the drying process.

Description

technical field [0001] The invention relates to the technical field of drying systems, in particular to an MVR belt drying system and a drying method thereof. Background technique [0002] Drying is an important process in industrial production, and it is involved in almost all industrial fields such as agriculture, food, chemical industry, ceramics, medicine and agricultural by-product processing. The energy demand of the drying process is relatively large, so it is of great significance to develop an efficient and energy-saving drying system. The pros and cons of the drying system and its drying process will directly affect the performance, quality, appearance and cost of the material. [0003] Paste materials usually have the characteristics of high moisture content, high solid content, high viscosity, strong hydrophilicity, and poor air permeability, making it difficult to achieve rapid and high-quality drying. Traditional drying methods have disadvantages such as long...
