A flat air-lift circulation type photosynthetic microorganism cultivation device

Abstract

The invention relates to a panel air lift circulation type photosynthetic microorganism culture device. A box is composed of a supporting part and a glass panel installed on the supporting part. Multiple reactor units sequentially connected in series are arranged in the box. Every two adjacent reactor units are separated through a connecting baffle installed on the supporting part. At least one aerating device is installed on the bottom in each reactor unit. One guide plate installed on the glass panel is arranged above each of the two ends of each aerating device. Each aerating device in each reactor unit communicates with a gas inlet tube. Gas enters the reactor units through each aerating device. A liquid outlet is formed in the bottom of each reactor unit. A glass cover plate provided with ventilation holes is connected to the top of the box in a sealed mode. A gap exists between each connecting baffle and the glass cover plate, and every two adjacent reactor units communicate with each other through the corresponding gap. The panel air lift circulation type photosynthetic microorganism culture device has the advantages that the cost is low, temperature control and cleaning are easy, energy consumption is low, photosynthetic efficiency is high, and the service life is long.

Description

technical field [0001] The invention belongs to a cultivation device for large-scale cultivation of photoautotrophic microorganisms in the field of biochemical industry, in particular to a flat air-lift circulation type photosynthetic microorganism cultivation device. Background technique [0002] After a series of experimental studies to determine the optimal culture conditions of microalgae and phytoplankton, the design of the reactor becomes the key. The culture system of microalgae is generally divided into an open culture system and a closed culture system. The biggest advantage of the open culture system is less investment, simple structure, low cost and simple operation; but there are disadvantages such as easy pollution, unstable production, and some algae species are not suitable. Compared with the open type, the closed type culture system has the following advantages: 1) No pollution, can realize pure species culture; 2) It is suitable for almost all microalgae an...

Problems solved by technology

[0008] For large-scale and high-density cultivation of microalgae, the traditional closed reactor has high cost, high temperature control cost, small ratio of light-receiving surface area to volume, irregular flow of internal algae liquid, prone to dead zones, algal cell adhesion, and energy consumption. Large and low reusability of the reactor due to difficulty in cleaning, the purpose of the present invention is to provide a flat air-lift circulation type photosynthetic microorganism cultivation device

The air-lift circulation photosynthetic microorganism cultivation device is a closed flat air-lift circulation photosynthetic microorganism cultivation device made of reinforced concrete and light-transmitting glass. It has good mixing and mass transfer effects, high light energy utilization rate, and shear It has the advantages of small and uniform cutting force, and at the same time, due to the outstanding advantages of low construction and operation costs, simple temperature control and cleaning, and long life, it effectively solves various unfavorable phenomena in the cultivation process, and is especially suitable for the growth of microalgae and phytoplankton.
