Ecological drying system

Abstract

The invention discloses an ecological drying system, and relates to the technical field of drying, a drying frame is provided with a main heat source water inlet and an auxiliary heat source water inlet, and the drying frame is connected with a primary heat source device and a secondary heat source device; the primary heat source device comprises a solar heat collection system, an air heat source pump system and a heat storage water tank; the solar heat collection system comprises a solar heat collector, the air heat source pump system comprises an air source heat pump and a heat circulating pump, and the secondary heat source device comprises an auxiliary heat water tank, a heating unit and an auxiliary heat circulating water pump. The primary heat source device for providing a main drying heat source and the secondary heat source device for providing an auxiliary heat source are arranged, so that the main drying heat source passes through the solar heat source system and the air heat source pump system, and heat generated by working of a control chip of the whole drying system is used as the auxiliary heat source; and the drying system is high in heat collection efficiency, improves the drying efficiency, and is energy-saving and environment-friendly.

Description

technical field [0001] The invention relates to the technical field of drying, in particular to an ecological drying system. Background technique [0002] Drying (backing dry) usually refers to the process of heating heat on wet materials and removing moisture from the wet materials to obtain solid products with lower moisture content. During thermal drying, the following two processes occur successively, and the drying rate is controlled successively. Process 1 Energy is transferred from the surrounding environment to the surface of the material, so that the moisture on the surface of the material evaporates, and the liquid is discharged from the surface of the material in the form of steam. The process rate depends on conditions such as temperature, air humidity, air velocity, heat transfer area and pressure of the material. Also called constant drop drying process. In process 2, the internal moisture is transferred to the surface of the material, and then the surface ev...

Problems solved by technology

However, these drying equipment have the following deficiencies: first, the thermal efficiency is low, and the drying cost is high; There are potential safety hazards such as electric leakage; third, coal-fired boiler drying equipment and oil-fired boiler drying equipment will produce harmful gases such as sulfur oxides, carbon monoxide, and carbon dioxide greenhouse gases, which seriously pollute the environment and require high maintenance costs.
