Drying method and equipment capable of realizing concentrated dehumidification, vertical alternate air-blowing and hot air recycling

Abstract

The invention discloses a drying method capable of realizing concentrated dehumidification, vertical alternate air-blowing and hot air recycling. Dry hot air passes through a final cavity at a discharge port to heat and dry products, then passes through adjacent cavities sequentially to perform the same heating and drying process and finally is discharged to the outside of a workshop through a first cavity at a feeding port, and concentrated dehumidification and complete recycling of hot air are realized. The invention further provides drying equipment capable of realizing concentrated dehumidification, vertical alternate air-blowing and hot air recycling. The drying equipment comprises a casing, wherein the multiple sequentially adjacent cavities are formed in the casing, and the number of the cavities is odd. According to the method and the equipment, concentrated dehumidification and vertical alternate air-blowing can be realized, hot air is collected continuously, all hot air is recovered, product drying effect is good, drying cost is low, and 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, alternating up and down blowing, hot air recovery and reuse, and the equipment, which belongs to the technical field of drying equipment. Background technique [0002] At present, in the application of drying equipment, a large amount of waste heat will be generated, and then this part of waste heat will be discharged directly without utilization. With the increasingly scarce energy situation and the increasing environmental pollution problems, energy saving is imminent. Therefore, the waste heat of drying equipment is not conducive to energy saving and environmental protection. Moreover, most of the existing hot air drying equipment uses each chamber to dehumidify and recycle hot air separately, also known as intermittent recovery. While recycling, while dehumidifying, only half of the hot air is recovered,...

AI Technical Summary

Problems solved by technology

Therefore, waste heat of drying equipment is not conducive to energy saving and environmental protection.

Moreover, most of the existing hot air drying equipment uses each chamber to dehumidify and recycle hot air separately, also known as intermittent recovery. While recycling, while dehumidifying, only half of the hot air is recovered, and all the hot air cannot be recycled. There is a lot of waste of heat and energy, and it can only be blown from the bottom to the top. The products that are exposed to the wind first are inconsistent with the drying of the products that are exposed to the wind after the top. The drying effect is average, the drying cost is high, and the drying efficiency is low.

[0003] In summary, there are obviously inconveniences and defects in the actual use of the existing technology, so it is necessary to improve
