Problems solved by technology

[0003] However, the inventors found in the process of implementing the present invention that if the flue gas and rice husk ash of the above-mentioned biomass power plant are simply used to produce white carbon black by carbonization, the production cost is relatively high, and the economy is relatively poor, and a large amount of carbon black still needs to be discharged. waste water and waste gas, destroying environmental resources

Embodiment Construction

[0038] Refer below figure 2 An embodiment of the spirulina cultivation system based on the white carbon black production system of the present invention will be described in detail.

[0039] Such as figure 2 As shown, this embodiment mainly includes:

[0040] The culture pond 31 that is provided with nutrient element inlet, described nutrient element inlet includes exhaust gas nutrient inlet and waste water nutrient inlet, draws a branch pipeline 32 from the carbon dioxide input pipeline 21 of institute's white carbon black production system 20 and is connected to all The exhaust gas nutrient inlet is used, and the waste water nutrient inlet is connected to the sodium carbonate and sodium bicarbonate mixed waste liquid outlet 22 of the white carbon black production system 20 through a wastewater pipeline.

[0041] Wherein, the branch pipe 32 extends into the bottom of the culture tank 31 from the waste nutrient inlet, and the branch pipe stretches into the surface of the i...

Abstract

Disclosed is a system for breeding spirulina based on a silica white production system, comprising a culturing pool provided with a nutrilite inlet having a waste-gas nutrient inlet and a waste-water nutrient inlet, wherein the waste-gas nutrient inlet is connected to a branch pipe from a carbon dioxide input pipe in the silica white production system, and the waste-water nutrient inlet is connected to an outlet of waste mixture containing sodium carbonate and sodium bicarbonate in the silica white production system via a waste-water pipe. Also disclosed is a corresponding method for breeding spirulina based on a silica white production system. The present invention achieves efficient utilization of waste water and waste gas from the silica white production system and substantially reduces the cost for breeding spirulina.

Description

technical field [0001] The invention relates to the field of environmental protection energy, in particular to a spirulina cultivation system and method based on a white carbon black production system. Background technique [0002] In biomass power plants in rice-producing areas, rice husks can account for more than 90% of the total fuel. After rice husks are burned, there are two products, namely flue gas and rice husk ash. There is about 12-20% CO in power plant flue gas 2 , the main component of rice husk ash is silica, while CO 2 Both silicon dioxide and silicon dioxide can be used as raw materials for the production of white carbon black by carbonization. figure 1 It is a schematic diagram of the process flow for producing white carbon black from flue gas and rice husk ash from a biomass power plant; figure 1 As shown, in the production process of silica, it is necessary to reduce the temperature and remove dust from the flue gas of the power plant in order to utiliz...
