Drying system

Abstract

The invention discloses a drying system which comprises a heat pump unit and a drying room, wherein a cold air pipe for importing cold air and a blowing pipe for exporting hot air are arranged on theheat pump unit; blowing openings are fully distributed in the side wall of one side of the drying room; air outlets are fully distributed in the wall of the other opposite side of the drying room; theblowing pipe is connected to the blowing openings; the air outlets communicate to a first exhaust pipe and a second exhaust pipe; the first exhaust pipe is connected to the outer side and the secondexhaust pipe is connected to the heat pump unit. The drying system can dry materials in different regions in the drying room synchronously smoothly through the structural design, so that the drying quality of the materials is optimized extremely, and the energy consumption and the time of system operation are reduced.

Description

technical field [0001] The present invention relates to the field of drying equipment, and more specifically relates to a drying system. Background technique [0002] Drying generally refers to various operations that remove water or other moisture from wet materials. For example: In daily life, wet materials are exposed to sunlight to remove moisture; in industry, silica gel, lime, concentrated sulfuric acid, etc. are used to remove moisture in air, industrial gases or organic liquids; in chemical production, heat and mass transfer is relied on, and hot air is used , flue gas and infrared rays to heat the wet solid material, so that the moisture or solvent contained in it is vaporized and removed. The purpose of drying is to make materials convenient for storage, transportation and use, or to meet the needs of further processing. For example, grains and vegetables can be stored for a long time after drying; synthetic resin can prevent air bubbles or moiré in plastic produ...

AI Technical Summary

Problems solved by technology

In the actual operation process, due to the limitation of the structure design of the existing heat pump drying equipment, the inlet and outlet of the air circulation into and out of the drying chamber are usually a single square or round mouth, and the dry and hot air enters the drying chamber and diffuses, and the cold and wet air is in the drying chamber. The room is shrunk and then discharged. In this way, the resistance of air entering and leaving the drying room is very large, resulting in uneven air speed and air volume in the drying room, especially the four corners of the drying room are often dead corners of ventilation, resulting in the drying progress of materials in different areas of the drying room. Inconsistency greatly affects the drying quality of materials and increases the energy consumption and time of system operation
