Carbon dioxide generating system heated by solar energy and carbon dioxide generating method

Abstract

The invention belongs to the technical field of comprehensive utilization of clean energy and relates to a carbon dioxide generating system heated by solar energy. The carbon dioxide generating system comprises an air pump, a water tank, a solar cell, a quartz tube, an insulating layer and a gas cabinet, wherein the quartz tube is arranged inside the insulating layer and internally filled with calcium oxide particles; air is pumped into the sealed water tank by the air pump; air containing water vapour above the liquid level in the water tank is introduced into one end of the quartz tube; the other end of the quartz tube is connected with a first valve and a second valve respectively through pipelines; the first valve is communicated with outside air; the second valve is communicated with the gas cabinet; the solar cell is used for heating the quartz tube through a heating wire arranged inside the quartz tube; and the generated carbon dioxide flows into the gas cabinet. The invention also provides a carbon dioxide generating method using the carbon dioxide generating system. The carbon dioxide generating system and the carbon dioxide generating method can be used for providing carbon fertilizer for plant growth in vegetable greenhouses simultaneously when reducing the carbon dioxide greenhouse gas in air, thereby avoiding the problem of environmental pollution.

Description

technical field [0001] The invention belongs to the field of comprehensive utilization of clean energy, and relates to a system and method for generating carbon dioxide by heating with solar energy. Background technique [0002] Carbon dioxide is the main gas that causes the greenhouse effect, and contributes more than 60% to the greenhouse effect. It is not difficult to capture the carbon dioxide emitted by the chimneys of power plants and factories, but it is completely captured in the exhaust pipes and flues of other systems (such as automobiles, aircraft, heating system, etc.) is impractical, so people are paying more and more attention to the technology of capturing carbon dioxide from the air. The use of solar heating quicklime to capture carbon dioxide can meet the needs of people to capture carbon dioxide anywhere, and will not affect the The environment is polluted and has a good application prospect. [0003] Carbon dioxide is one of the main raw materials for pho...

AI Technical Summary

Problems solved by technology

[0003] Carbon dioxide is one of the main raw materials for photosynthesis of vegetables. The concentration of carbon dioxide in the air is generally about 385 microliters per liter, which is far from meeting the needs of high-quality and high-yield vegetables.
