Fully enclosed ground heating runway pool microalgae breeding system

Abstract

The fully enclosed floor heating microalgae breeding system for a track pool relates to a fully enclosed floor heating microalgae breeding system which uses groundwater, solar energy, etc. to adjust the temperature and temperature of the water environment of the track pool. A fully enclosed floor heating runway pool (13) is adopted, and heat exchange pipes (12) are laid under the pool to connect a hot water device and a cold water device respectively. The hot water device is formed by series connection of the heat preservation water tank (4), the water heater, the first water pump (17), and the underground return pool (3) through water pipes. Cold water device is made of second water pump (7) and underground water well (8) and water pipe. Use solar collectors to provide hot water, and provide heat source for the circulating water in the runway pool in low temperature weather; use groundwater to cool down the circulating water in the runway pool in high temperature weather, and has the characteristics of underground and closed, can obtain constant ground temperature, and effectively prevent Heat dissipation and water evaporation can achieve all-weather factory production throughout the year, and has the positive effects of simple structure and low cost.

Description

technical field [0001] The invention belongs to the field of microalgae cultivation, and in particular relates to a fully enclosed ground heating microalgae cultivation system which uses groundwater, solar energy and the like to adjust the temperature and temperature of the water environment of the raceway pool. Background technique [0002] Microalgae are a kind of autotrophic plants that are small in size and widely distributed on land, lakes, and oceans and can perform photosynthesis. The fats, polysaccharides, proteins, and pigments produced by their cell metabolism are widely used in bioenergy, food, medicine, and genetic engineering. This field has great development prospects and application value. The fast reproduction speed of microalgae is conducive to large-scale industrial cultivation, especially oil-rich microalgae, whose oil content can reach more than 50% of the dry weight, which provides an effective green and environmentally friendly way to solve the world's ...

AI Technical Summary

Problems solved by technology

However, as mentioned above, compared with the underground track-type microalgae cultivation system, this above-ground system has defects such as high cost, maintenance and management costs, and low heat energy utilization, which is still not conducive to large-scale factory production.
