Embodiment

[0009] A new carbon dioxide gas fertilizer application method, the method is to remove SO in flue gas by absorbing liquid 2 , NO x and other harmful gases, and then the resulting CO 2 The mixed gas of harmless gas is passed into the air chamber as gas fertilizer; the specific steps are as follows: (1) Connect the industrial waste gas to the air inlet of the purification device, install a filter screen in the air inlet pipe to filter out solid dust, There is a circulating cold water pipe on the periphery of the intake pipe, and the exhaust gas is cooled with cold water; (2) The filtered exhaust gas is sucked into the purification device by an air pump, and the gas is exposed to microbubbles and absorbed liquid through the built-in aeration head. Reaction; (3) the CO that will be obtained 2 The gas fertilizer is output from the gas outlet through the gas pipeline and enters the gas delivery system for delivery.

[0010] It is characterized in that the absorption liquid is Na ...

Abstract

The invention discloses a novel carbon dioxide gas fertilizer additional application method, which is characterized in that absorption liquid is used for removing harmful gas such as SO2 and NOx in smoke gas; then, obtained mixed gas of CO2 and harmless gas is used as a gas fertilizer to be introduced into a gas chamber. The method comprises the following concrete steps that (1) industrial waste gas is connected with a gas inlet of a purification device; a filter screen is arranged in a gas inlet pipeline for filtering away solid state dust; a circulating cold water pipe is arranged at the periphery of the gas inlet pipeline; cold water is used for reducing the temperature of waste gas; (2) sucking filtered waste gas into the purification device by an gas extracting pump; through a built-in aeration head, gas is aerated into microbubbles to take full reaction with the absorption liquid; (3) the obtained CO2 gas fertilizer is output from a gas outlet through a gas conveying pipeline toenter a gas conveying system to be conveyed and used. When the method is used, the exhaust of industrial waste gas can be reduced; the purified waste gas is used as a CO2 gas fertilizer to be reutilized; the project belongs to a very environment-friendly project.

Description

technical field [0001] The invention relates to a waste gas treatment method, in particular to a novel method for increasing application of carbon dioxide gas fertilizer. Background technique [0002] At present, my country's greenhouse area has reached more than 50% of the total area of ​​the world, and it has become the largest producer of greenhouse vegetables in the world today. CO 2 It is the raw material for plant photosynthesis, traditional CO 2 CO 2 The fertilizer source is not safe and stable enough, and the cost of additional application is high; in addition, CO 2 Increased emissions will also cause a series of environmental problems. Therefore, domestic and foreign scholars agree that CO 2 The key to gas fertilizer application technology is to find safe, stable and cheap CO 2 fertilizer source. Contents of the invention [0003] The object of the present invention is to provide a novel carbon dioxide gas fertilizer application method to convert industrial...
