Carbon dioxide gas transfer device

Abstract

The invention discloses a pipeline part used for conveying carbon dioxide gas, and particularly relates to a carbon dioxide gas transfer device. The carbon dioxide gas transfer device is arranged between a carbon dioxide generator and a water spraying pipeline, and comprises a transfer device body, a heating unit and an air supply unit, wherein the heating unit and the air supply unit are arranged in the transfer device body. A gas inlet connected with the carbon dioxide generator and a gas outlet connected with the water spraying pipeline are formed in the transfer device body. The air supply unit supplies air to the gas outlet. A gas guide urn is fixedly arranged in the transfer device body. Two opposite ports are arranged on the gas guide urn. One port is an inlet connected with the gas inlet through a gas guide pipe, and the other port is an outlet facing the gas outlet. A cover body used for sealing and covering the outlet is arranged on the gas guide urn. A set of flat gas outlet holes are formed in the circumferential side of the cover body. The carbon dioxide gas transfer device overcomes the technical defect that in the prior art, pipe blockage and influences on growth of part of plants exist, and the carbon dioxide gas transfer device used for providing dry ice sublimation is provided.

Description

technical field [0001] The invention relates to a pipeline component for transporting carbon dioxide gas, in particular to a carbon dioxide gas transfer device. Background technique [0002] In recent years, with the country's emphasis on facility agriculture, governments at all levels have vigorously developed the solar greenhouse industry, which has become an important way for rural farmers to increase their income. During photosynthesis, crops need to absorb a large amount of carbon dioxide (gas fertilizer), generally at 1000ppm, while the carbon dioxide content in solar greenhouses is far below (generally only 300ppm). Therefore, some methods are often used to increase the carbon dioxide content in the greenhouse. The buried dry ice method and biological cultivation method are not easy to control the amount of carbon dioxide produced, so they are used less; the most commonly used method at present is the method of producing carbon dioxide by chemical reaction, that is, ...

Problems solved by technology

[0004] However, when dry ice sublimates, it needs to absorb a large amount of heat. If the carbon dioxide generator is directly connected to the water spray pipeline, the accumulated water in the water spray pipeline will freeze instantly, and some may even cause pipeline blockage; It will reduce the temperature of the greenhouse. Although it has little effect on the overall temperature of the greenhouse, the growth of the plants adjacent to the sprinkler nozzle will be affected.
