Problems solved by technology

Drying these agricultural products, aquatic products, and wastes in the production process of agriculture and forestry can reduce the storage and transportation costs of these materials and commodities and improve the economic benefits of rural areas. However, if traditional energy is used, not only the cost is high, but also the thermal efficiency is low and the environment is polluted.

Embodiment Construction

[0025] Below in conjunction with accompanying drawing, specific embodiment of the present invention is described in further detail:

[0026] Such as figure 1 As shown, a drying system combining hot air and cold air drying of the present invention includes a solar greenhouse 1, an air condenser 2, a water bath dust collector 9, a heat source, an air heater 4, a flue gas refrigeration device, an air cooler 8, a cooling The tower 11, the dehydrator 10, the pipes connecting each device and the valves 13.1-13.15 and fans 7.1-7.6 arranged on the pipes. details as follows:

[0027] Such as figure 2 As shown, the orientation of solar greenhouse 1 is different according to the different regions. In principle, its front should face the direction with the strongest solar radiation. In the northern hemisphere, it is generally facing south. The building structure of the solar greenhouse 1 is a frame structure, and the top surface and the east, west, and south sun-receiving surfaces are...

Abstract

The invention relates to a drying system combining hot air and cold air drying, comprising a solar greenhouse (1), an air condenser (2), a water bath dust collector (9), a heat source, an air heater (4), a flue gas refrigeration device, A cooling fan (8), as well as pipes connecting each device and valves and fans provided on the pipes; the solar greenhouse (1) is a sealed structure, the air condenser (2) is a cylindrical structure, the heat source and the air heater (4) Connection, the air inlet of the solar greenhouse (1), the air outlet of the air condenser (2) and the outlet of the air heater (4) are connected through pipes, and the air outlet of the solar greenhouse (1) is connected to the air outlet of the air condenser (2). The upper air box (2.1) is connected through a pipeline, and the flue gas outlet of the air heater (4) is connected with the flue gas refrigeration device. The invention can completely use the combination of solar energy and hot and cold air to dry different materials, and realizes the multi-level utilization of energy and improves the thermal efficiency of drying.

Description

technical field [0001] The invention belongs to the drying technology utilizing solar energy, and specifically refers to a drying system combining hot air drying and cold air drying. Background technique [0002] In recent years, the global energy crisis and the resulting energy "scramble" are gradually escalating. At the same time, the current energy structure dominated by conventional energy such as coal, oil, and natural gas is still going on. The exhaust gas is discharged into the atmosphere, which not only wastes energy, but also pollutes the environment. For this reason, the development of new energy has been vigorously developed in recent years, but the focus is on industrial projects and cities, and agriculture is only used in solar greenhouses, and little progress has been made in other aspects. [0003] Solar energy also has a vast space in rural areas, and the quality of life of farmers needs to be greatly improved, and farmers need to get rich quickly. There ar...
