Problems solved by technology

A large amount of carbon dioxide is released into the air, which not only wastes production materials and increases production costs, but also, because carbon dioxide is the most important greenhouse gas, excessive emission of carbon dioxide will increase the concentration of carbon dioxide in the air, aggravate the greenhouse effect, and have a negative impact on global climate change

Embodiment Construction

[0050] 1000m below 2 The supporting carbon dioxide inflator for the culture pond is taken as an example, and the present invention will be further described in detail in conjunction with the accompanying drawings.

[0051] The total length of the breeding pond is 66 meters, the width is 16 meters, the two ends are semicircles with a diameter of 16 meters, the middle is a rectangle, the pool wall is 35cm high, the depth of algae liquid is 20cm, and the total amount of algae liquid is 200m 3 . according to figure 1 , figure 2 It can be seen that the device for replenishing carbon dioxide is composed of an inflatable tank, an inflatable pipe bracket, a carbon dioxide inflatable pipe, an air aeration pipe, a carbon dioxide gas supply system and an air gas supply system. The structural relationship is:

[0052] 1. The structure of the inflatable device

[0053] (1) Inflatable tank main body

[0054] The inflatable tank is made of brick and concrete. It is located at 1 / 4 of th...

Abstract

The invention discloses a carbon dioxide supplementary device of microalgae culture pond, which comprises the following parts: aerating groove area I, aerating groove area II, carbon dioxide aerating pipe, air aeration pipe, carbon dioxide supplying system, air supplying system and brack, wherein the aerating groove is next to the culture pond; the aerating groove area I connects the culture pond through channel as well as the aerating groove area II; one end of carbon dioxide aeration pipe connects the carbon dioxide supplying pipe; one end of air aeration pipe connects the air supplying pipe with a block of baffle in the aeration groove. The invention improves the carbon dioxide absorbance and utilizes the carbon dioxide effectively, which possesses obvious economical and environmental benefit.

Description

technical field [0001] The present invention relates to a kind of microalgae cultivation pool supplementing carbon dioxide (CO 2 ) device, the device can improve the absorption rate of algae liquid to carbon dioxide, effectively utilize carbon dioxide, and reduce the release of carbon dioxide into the air during the production process. Background technique [0002] The carbon source for autotrophic growth of plants in nature comes from carbon dioxide in the air. The carbon dioxide in the air is far from meeting the carbon source demand for rapid growth and reproduction of artificially cultivated microalgae. Taking the mass cultivation of spirulina as an example, the rate of absorption of carbon dioxide from the air by the algae liquid is about 0.04mmol / m 2 .min, can only provide 2.5g. / m 2 .d Carbon sources required for production. In order to maintain the pH value of the culture solution, provide the carbon source required for algae growth and repr...
