Problems solved by technology

[0003] The cultivation process of the open photobioreactor is greatly affected by the natural environment such as light and temperature, and is easily polluted by fungi, protozoa and other algae species. At the same time, the water evaporates seriously and the supply of carbon dioxide is insufficient. Low, high harvesting cost

Abstract

The invention relates to a device and a method for culturing microalgae in a large scale, in particular to a cylinder-shaped thin film reactor device for fast culturing the microalgae. In the cylinder-shaped thin film reactor device, a main body is a vertical steel structure cylinder-shaped or polygonal cylinder bracket, the upper end and the lower end of the bracket are formed by a plurality of stainless steel metal straps arranged in a circular shape through welding, and the cylinder-shaped or polygonal cylinder bracket is arranged in a rectangular formation or a square formation. The lower end of the cylinder-shaped thin film reactor is opened, a pipe is arranged at the position of an opening, the pipe and a thin film are integrated to be a closed structure, the pipe is of a screw structure, the reactor is directly sleeved on the base of the cylinder-shaped bracket, and the upper end of the reactor is provided with an exhaust port, a feed port and an inlet port. A top cover of the reactor is installed and fixed at the upper end of the cylinder-shaped bracket so that direct impact of rainwater, and the like and attachment of dust can be avoided. The base of the cylinder-shaped bracket is provided with the opening, the opening is of the screw structure and can be connected with the pipe of the opening at the lower end of the thin film reactor, and raw material belts are filled in connection position of the opening and the pipe for closing.

Description

technical field [0001] The invention relates to a cylindrical thin-film photobioreactor system used for microalgae cultivation in the field of biotechnology, in particular to equipment and methods for industrialized cultivation of microalgae by utilizing waste gas and waste heat from power plants and adopting LED energy-saving lighting devices. Background technique [0002] Power plant exhaust gas contains dust, CO, CO 2 , sulfide and other harmful substances, will cause environmental pollution if discharged into the atmosphere, and will also aggravate the greenhouse effect. Autotrophic microalgae can convert CO 2 Photosynthesis for carbon sources produces a variety of high value-added products such as protein, vitamins, etc. Some algae with high oil content can also be used to produce biodiesel. Therefore, if the CO in the exhaust gas can be 2 Recycling for the cultivation and culture of microalgae will have dual value of economy and environmental protection. [0003] ...
