Abstract
The invention discloses a method for using purified waste gas as gas fertilizer, and is characterized in that the method adopts absorption liquid to remove harmful gas such as SO2, NOx and the like in flue gas, and uses mixed gas of the obtained CO2 and harmless gas as gas fertilizer; the method particularly comprises the following steps: (1) introducing industrial waste gas into a gas inlet of a purification device, mounting a filter screen in a gas inlet pipe to filter solid dust, mounting a circulating cold water pipe at the periphery of the gas inlet pipe, cooling the waste gas by cold water; (2) pumping the filtered waste gas into the purification device by a suction pump, aerating the gas into micro bubbles through a built-in aerator, allowing the micro bubbles to react with absorption liquid fully; (3) outputting the obtained CO2 gas fertilizer from a gas outlet through a gas pipeline to enter a gas conveying system for conveying and using. The method can reduce industrial waste gas emission, uses the purified waste gas as CO2 gas fertilizer for recycle, and belongs to a quite environment-friendly project.
Description
Technical field
The present invention relates to waste gas, the waste gas after specifically utilization purifies is as the method for carbon-dioxide gasfertilizer.
Background technology
China's greenhouse area reaches more than 50% of the global gross area at present, has become the greenhouse vegetable producing country of world today's maximum.CO
2The raw material of photosynthesis of plant,, traditional C O
2Gas fertilizer enriches technology and all has CO
2The inadequate safety and stability of the source of manure enriches the high in cost of production problem; In addition, CO
2Increase discharging, also can cause series of environmental problems.Therefore, Chinese scholars is unanimously thought CO
2The key that gas fertilizer enriches technology is to find safe, stable, cheap CO
2The source of manure.
Summary of the invention
The object of the present invention is to provide and a kind ofly utilize waste gas after the purification as the method for carbon-dioxide gasfertilizer, industrial waste gas is converted into CO
2Gas is fertile, for the agricultural resources utilization of industrial waste gas provides effective way.
Technical scheme of the present invention is: a kind of with the method for waste gas after purifying as gas fertilizer, the method is with the SO in the absorption liquid removal flue gas
2, NO
xDeng pernicious gas, again with gained CO
2And the mist of innocuous gas passes into air chamber as gas fertilizer; Concrete steps are as follows: (1) accesses the air inlet of purifier with industrial waste gas, and filter screen is installed in admission line, with the solid-state dust of elimination, is arranged with the cold water pipe of circulation outside admission line, with cold water waste gas is lowered the temperature; (2) in the waste gas suction purifier after will filtering with aspiration pump, by built-in aeration head gas is exposed to the sun and fully to react for microvesicle and absorption liquid; (3) with the CO that obtains
2Gas fertilizer enters gas delivery system through gas pipeline by gas outlet output and carries use.
Described absorption liquid is the Na that contains 50g/L urea, 10g/L
2SO
3, 7.5g/L Ca (OH)
2Solution.
Described outlet pipe is provided with leaving air control valve.
Advantage of the present invention: adopt this method can reduce the discharging of industrial waste gas, especially to the recycling of coal-burning power plant's waste gas, will purify afterwards waste gas as CO
2Gas fertilizer recycles, and is the project of very environmental protection.
The specific embodiment
Embodiment
A kind of with the method for waste gas after purifying as gas fertilizer, the method is with the SO in the absorption liquid removal flue gas
