Problems solved by technology

[0003] At present, in the existing hot air drying equipment, each chamber dehumidifies and recycles hot air separately, also known as intermittent recovery. While recycling, while dehumidifying, only half of the hot air is recovered, and the hot air cannot be fully recovered. Utilization, heat and energy are wasted more, and the drying effect is average, the drying cost is high, and the drying efficiency is low

Embodiment 1

[0026] Example 1 A drying method for centralized dehumidification and full recovery and reuse of hot air

[0027] The present invention provides a drying method with centralized dehumidification and full recovery and reuse of hot air. The dry hot air passes through the last chamber at the discharge port to heat and dry the product, and then passes through the adjacent chambers for the same heating. During the drying process, it is finally discharged from the outside of the workshop through the first chamber at the feed inlet to realize centralized dehumidification and all hot air can be recycled for reuse.

[0028] The dry air is sucked from the last drying chamber at the outlet of the drying equipment by a centrifugal fan, heated to a set temperature by a heat exchanger, and then blown upwards through the object to be dried for heating and drying. After passing through the object to be dried, the hot air with a certain temperature and a small amount of moisture is sucked into...

Embodiment 2

[0031] Example 2 A drying equipment for centralized dehumidification and full recovery and reuse of hot air

[0032] like Figure 1-2 As shown, the present invention provides a drying device with centralized dehumidification and full recovery and reuse of hot air, which includes a housing 1, and the housing 1 is provided with a plurality of sequentially adjacent chambers.

[0033] The outside of the housing 1 is provided with a heat exchanger 3 and a centrifugal fan 4, and there are multiple heat exchangers 3 and centrifugal fans 4. Specifically, each chamber corresponds to a heat exchanger 3 and a centrifugal fan 4. Fan 4.

[0034] The centrifugal fan 4 communicates with the heat exchanger 3 , and the heat exchanger 3 communicates with the chamber inside the housing 1 .

[0035] One side of the housing 1 is provided with a material inlet 11, and the other side of the housing 1 is provided with a material outlet 10,

[0036] The top of the chamber is provided with a moistur...

Abstract

The invention discloses a centralized moisture exhaust and hot air all recycling and reusing drying method. Dry air is sucked from a final drying cavity at a discharge outlet of a drying device through a centrifugal fan, is heated to the set temperature through a heat exchanger and is blown upwards over a material to be dried to conduct heating and drying. After passing through the material to bedried, the hot air with a certain temperature and a little moisture air is sucked into the centrifugal fan of the last adjacent drying cavity through an exhaust outlet on the upper portion of the drying cavity to conduct secondary heating and then conduct heating and drying on the material to be dried in the last cavity. The process is conducted repeatedly. The humidity of the hot air is higher and higher. Finally, the hot air is discharged through the first drying cavity at the discharge port of the drying device to complete the whole drying process. The invention further provides the centralized moisture exhaust and hot air all recycling and reusing drying device. Through the centralized moisture exhaust and hot air all recycling and reusing drying method and device, moisture of the hotair can be exhausted in a centralized, and the hot air can be collected continuously and be completely recycled and utilized; the drying effect of products is good, the drying cost is low, and the drying efficiency is greatly improved.

Description

technical field [0001] The invention relates to a drying equipment for hot air recovery, in particular to a drying method and equipment for centralized dehumidification and full recovery and reuse of hot air, and belongs to the technical field of drying equipment. Background technique [0002] Drying equipment refers to a combination of a series of mechanical equipment that dries moisture or other liquids on the surface of objects through certain technical means. The current popular drying technologies mainly include infrared drying, microwave heating drying and hot air drying. Hot air drying is more widely used. [0003] At present, in the existing hot air drying equipment, each chamber dehumidifies and recycles hot air separately, also known as intermittent recovery. While recycling, while dehumidifying, only half of the hot air is recovered, and the hot air cannot be fully recovered. Utilization, the waste of heat energy is more, and the drying effect is average, the dr...
