Embodiment Construction
[0012] see Figure 1-Figure 3 , the specific implementation mode adopts the following technical scheme: its flow process includes a hanging type release process and a ground type release process, and the hanging type release process is as follows: a storage tank / Dewar tank / carbon dioxide cylinder 1 passes through The vaporizer 2, the pressure reducer 3, and the distribution valve 4 are delivered to the air supply valve 5, and the air supply valve 5 is connected to one or more greenhouses through the main air supply pipeline 6, controlled by the electric control box 7, and the secondary pressure reducer 8 Decompression, the solenoid valve 9 receives the opening and closing instructions transmitted from the PLC / DCS / DDC in the electric control box 7, connects the vertical release pipe 11 through the 5mm-100mm gas fertilizer delivery branch 10, and releases it through the release terminal 12;
[0013] The ground release process is as follows: a storage tank / Dewar tank / carbon dioxi...

A gas pipeline conveying flow for ecological agricultural greenhouses relates to the technical field of gas conveying flows. A suspended discharging flow is as follows: gas is conveyed from a storage tank / a dewa flask / a carbon dioxide cylinder to a gas supply valve through a vaporizer, a reducer and a distributing valve, the gas supply valve is communicated with one or more greenhouses through a gas supply main pipeline, the pressure is reduced through a secondary pressure reducer by virtue of control of an electric control box, an electromagnetic valve receives opening and closing instructions transferred from PLC / DCS / DDC in the electric control box and is communicated with a suspended release pipe through a 5-100 mm gas-fertilizer conveying branch pipe, and the gas and fertilizer are applied through a release terminal; a ground discharging flow is as follows: the pressure is reduced by the secondary pressure reducer by virtue of control of the electric control box, and the electromagnetic valve receives opening and closing instructions transferred from PLC / DCS / DDC in the electric control box and is communicated with a porous release pipe with release holes for discharge through the 5-100 mm gas-fertilizer conveying branch pipe. The pipeline provided by the invention is convenient to control and operate, is high in safety and energy-saving and environmental-friendly, the using cost is greatly lowered as a result of storage and transportation and usage modes, and the pipeline is suitable for being used and popularized in a large range.
Description
Technical field: [0001] The invention relates to the technical field of gas transportation process, in particular to a gas pipeline transportation process in an ecological agricultural greenhouse. Background technique: [0002] Both humans and animals need to absorb oxygen to provide the energy they need and exhale carbon dioxide waste gas to survive on the earth, while all plants on the earth are just the opposite, absorbing waste gas carbon dioxide and releasing oxygen, even the ocean is no exception. Since the end of the 1970s, developed countries have begun to apply carbon dioxide fertilizer application technology to increase production and income in agricultural greenhouses, and have achieved significant economic benefits. At present, this technology has been widely used in Europe, North America and Japan. The popularization and application of CO2-increasing technology has been used in 50% to 70% of greenhouse crops in the United States and more than 80% of greenhouse c...
