Embodiment 1

[0035] Example 1: Drying of agricultural and sideline products

[0036]Use agricultural greenhouses commonly used in rural areas as regular confined spaces; install a proper amount of unpowered fans on the top of the greenhouse or set up a proper amount of unpowered fans next to the greenhouse, and their exhaust ports are connected to a section of pipe equipped with a valve and the other end is inserted into the upper or top layer of the greenhouse ; Place a solar air heat collector near the big shed, where the sun can shine; connect one end of one or more PVC hoses with valves to the bottom of the big shed, and the other end into the outlet of the solar air heat collector ; At the same time, in order to store heat, spread heat storage materials or sand on the ground in the greenhouse. Multi-layer shelves are placed in the greenhouse, and agricultural and sideline products are spread on each layer of the shelves.

[0037] When agricultural and sideline products need to be dried, y...

Embodiment 2

[0041] Example 2: Heating and heating of biogas digesters under cold weather conditions.

[0042] The following is only an example of a biogas digester (tank) buried in the ground.

[0043] First build or put a prefabricated pond underground, the pond should be no smaller than the part of the methane tank (tank) buried underground. Install some structural parts that can safely and stably support the maximum weight of the entire biogas digester (tank) in this pond, or these supporting structural parts have been installed in the lower part of the digester (tank), and the bottom of the digester (tank) can be just right with the bottom of the digester (tank). It is flush or lower than the bottom of the biogas digester (tank); after the biogas digester (tank) is put into this pool, the gap between the pool and the biogas digester (tank) on the ground is sealed; this way the pool and the biogas digester (tank) ) Formed a confined space.

[0044] Use the bracket to erect the turbine vent...

Embodiment 3

[0050] The third embodiment is to adjust the indoor temperature of the house (residential) and improve the indoor air quality, so as to realize the green and energy-saving of the house (residential).

[0051] At present, in order to meet the needs of heat preservation and sound insulation, the airtight performance of houses (houses) has been generally improved, so that houses (houses) cannot be naturally ventilated, and fresh air is isolated outside, resulting in a decrease in indoor air quality.

[0052] Install or erect an unpowered fan on the top of the house (residential), and its exhaust port is connected to the exhaust port on the inner wall of the house (residential) through a pipe, and this exhaust port is equipped with a valve; on the top of the house (residential) Or install the solar air heat collector at the best position on the outer wall by the sun. The air outlet of the solar air heat collector is connected with the air inlet on the lower inner wall of the house (re...

Abstract

The invention relates to a novel method for performing heating, warming and drying treatment to a material by using solar energy hot gas flow generated in a non-power way. The invention has the following advantages that (1) the heating, the warming and the drying treatment can be performed to the material without a power. (2) The noise, the pollution and the operation cost are free during the operating process. (3) The thermal gas generated by other methods can be taken as a standby air source. (4) The wet discharge, the drop in temperature, the ventilation and the drying in the normal temperature of the material can be realized. (5) The invention also can be used for adjusting the indoor temperature and the humidity of a house (residence), improving the indoor air quality and to realize the green energy conservation of the house (residence). (6) The invention also can be used for a field operation or the field such as the national defense. (7) The invention can be used as a greenhouse. (8) The system structure of the invention is simple, the investment is small, the service life is long, and the energy is saved and environment is protective. (9) The invention is easily applied in the industrial and agricultural production and the daily life.

Description

Technical field [0001] The invention relates to a new method for heating, heating, and drying materials using hot air generated by solar energy, in particular to a method for heating, heating, and drying materials using solar hot air generated in an unpowered manner new method. Background technique [0002] As we all know, solar energy is an inexhaustible renewable energy and alternative energy. my country is rich in solar energy resources, and the solar energy available every year is equivalent to the calorific value of 12,000 tons of standard coal. Therefore, the market prospects for solar thermal utilization are very broad. [0003] With the current rapid economic development, shortages of non-renewable energy sources such as electricity, coal, and oil have frequently appeared. Energy shortages and environmental pollution have increasingly become bottlenecks restricting social and economic development. For this reason, the national renewable energy development policy encourage...
