Problems solved by technology

Therefore, the temperature control in the drying box is poor and the heat is unstable
At the same time, in winter, night and continuous rainy weather and other sunlight conditions do not allow, only rely on energy storage heat to dry, without other auxiliary heat sources, the controllability and stability of continuous drying are poor.
[0011] 2. The circulation heat transfer efficiency of traditional solar collectors is not high, and the efficiency of solar energy conversion to heat energy is low
Due to the heat loss in the two heat exchanges, the drying efficiency is low and the overall energy utilization rate is low
[0012] 3. The volume of the heat exchange coil in the regenerator is fixed, and the stored heat is only adjusted by increasing or decreasing the volume of the heat storage medium. In actual operation, the controllability of the heat storage is poor, and the operation is inconvenient
[0013] 4. The above structure is a fixed placement method, and the mobility is poor

Embodiment Construction

[0066] Specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0067] like figure 1 As shown, the mobile solar drying device of the present invention includes five parts: a heat collection system, a drying system, a heat storage system, an automatic or manual control system, and a mobile system connected to each other through pipelines, wherein,

[0068] The drying system is located on the upper part of the heat storage system; the heat collection system, drying system, heat storage system and automatic or manual control system are fixedly installed on the mobile system.

[0069] Heat collection system, which absorbs solar energy and converts it into thermal energy for storage; drying system, which continuously dries wood; heat storage system, which stores the heat energy absorbed by the heat collection system and exceeds the heat required by the drying system to dry wood; automatic or manual control system...

Abstract

The present invention discloses a wood drying method by using solar energy, comprising the steps of: putting the wood to be dried in a drying cabinet (8); supplying heat to the drying cabinet; and stopping the supply of heat when the temperature T2 of the drying cabinet (8) is higher than the setting drying temperature of the wood to dry the wood under the setting drying temperature. The movable drying device by using solar energy has stable running, constant drying temperature and continuous drying function with lower power consumption, higher solar energy conversion efficiency and good drying quality, thereby reducing the drying cost.

Description

technical field [0001] The invention relates to utilization of solar heat, in particular to a solar drying device in which working fluid flows through a heat collector and a drying method using solar energy. technical background [0002] Energy is an important material basis for economic construction and social development. Due to the increasing demand for energy in the world, the increasing shortage of conventional energy, rising oil prices, global warming and environmental pressure, countries around the world are turning their strategic sights to renewable energy in order to seek energy security and sustainable development of human society. develop. Therefore, renewable new energy will become the top priority of energy development in the 21st century. As a clean, cheap and inexhaustible renewable energy, solar energy is being valued by various countries and industries, and has attracted more and more attention. my country is very rich in solar energy resources. Accordin...
