Photosynthetic microorganism cultivation production system

Abstract

The invention discloses a photosynthetic microorganism cultivation production system. The photosynthetic microorganism cultivation production system includes a ventilation circulation system, whereinthe ventilation circulation system comprises a gas supply unit, a ventilation pipeline unit, a rubber ball, a solenoid valve and a valve; the gas supply unit includes an air extraction device, an airsupply end purification device, precise air pressure detection controllers, a solenoid valve control system; the precise air pressure detection controllers are installed at both ends of a culture pipeline; the air extraction device adopts an active air pressure filtration purification device to accurately supply air, and used for keeping the air pressure difference between the inside and outside of the culture pipeline to be not more than + / -50Pa; and the air extraction device and the air supply end purification device are installed at both ends of the culture pipeline. According to the photosynthetic microorganism cultivation production system, the defects of the current two representative culture equipment systems are overcome, and culture, filtering, cleaning and sterilization are integrated, the safe service life of the equipment is greatly prolonged, the workload is significantly reduced, the working efficiency of culture is significantly improved, and the product quality is significantly improved.

Description

technical field [0001] The invention relates to the technical field of microorganism cultivation, in particular to a photosynthetic microorganism cultivation and production system. Background technique [0002] The use of sunlight to cultivate microorganisms beneficial to humans on a large scale has always been the pursuit of people, and many related invention patents have emerged at home and abroad. Among these invention patents, pipeline cultivation equipment patents are more popular because of higher cultivation efficiency and better product quality. Pipeline cultivation equipment can be roughly divided into two categories: one is the vacuum negative pressure operation equipment (cultivation system) represented by Shenzhen Lvdebao Health Products Co., Ltd. It is a positive pressure driven gas supply production system represented by Shanghai Guangyu and Yueqing Guangyu Biotechnology Co., Ltd. In the former, equipment (pipelines) and microorganisms are in a state of vacuu...

Problems solved by technology

In the former, equipment (pipelines) and microorganisms are in a state of vacuum and low pressure for a long time, which may easily cause pipeline rupture (air pressure acts on the pipe wall inwardly) and microbial growth distress (lack of carbon dioxide), and the air cannot be effectively purified (if the pore size of the filter equipment is too small, will cause the culture solution to be pumped out of the tube); and although the latter has noticed the defects of the former, the equipment is under positive pressure for a long time, which is also easy to cause pipeline rupture (the gas expands outwards and acts on the tube wall) and microbial growth Inhibition phenomenon - because the algae we choose are all cultivated under normal pressure or close to normal pressure

Moreover, whether it is positive pressure or negative pressure, the movement of the liquid in the pipeline is driven by the movement of the air bubbles (clusters). Due to the low density of the gas, it always floats on the water surface, so that the pipeline is almost only the upper layer of liquid. In the flow, the lower microorganisms (algae) and the liquid hardly move, which will easily cause the lower microorganisms (algae) to gather and die and the liquid to become smelly - the larger the inner diameter of the pipe, the more obvious this phenomenon. Therefore, we propose a photosynthetic microorganism Cultivate production system
