Series connected type unit cell algae optical biological reaction device

Abstract

The invention relates to a single cell algae cultivation device and provides a series connection type single cell algae photobiological reaction device to increase the production of the single cell algae and prolong the disinfection interval time of the device, the key points of the device are that: the device is formed a plurality of photobiological reaction units which are connected in series and have the same structure, each unit is provided with a water drain outlet, a sewage drain outlet and a base of an air inlet pipe, the edge of an opening at the lower end of a light transparent thin film cultivation cylinder is fixed by a lower fixed sleeve and the base which are connected by a bolt, the edge of the opening at the upper end of the light transparent thin film cultivation cylinder is fixed by an upper fixed sleeve and a top cover with water feed inlets which are connected by the bolts, a grid type shaping cover is inserted in the inner wall of the upper fixed sleeve and the lower fixed sleeve, the lower parts of the units are fixed on a support by the base, the upper parts of the units are suspended on a top frame by a pipe part and a connecting part which are connected with the water feed inlets, all the units are connected in series correspondingly by the own water feed inlet and the water drain outlet, a supply box which is arranged at the upper part of the top frame supplies an algal species and a culture liquid by a flowmeter, and the water feed inlet of the last unit is connected with a single cell algae collection box.

Description

technical field [0001] The invention relates to a cultivation equipment for algae. Background technique [0002] The applicant filed an application on May 30, 2005. The publication number is CN1699541A, and the name is a patent application for a photobioreaction device for unicellular algae. The conduit on the upper part of the nozzle. Insert the fixed sleeve into the Z-shaped notch on the outer wall of the base. The opening edge of the light-transmitting film culture tube is located at the junction of the base and the fixed sleeve, and is pressed by the bolts on the outer boss of the base and the fixed sleeve. The lower part is inserted into the spigot of the fixed sleeve, and the photobiological reaction unit is formed by the above-mentioned parts, which are interlaced with each other through their respective water inlets and outlets to form a culture system. However, it has the following disadvantages: since the water inlet of the photobiological reaction unit at the fr...

AI Technical Summary

Problems solved by technology

However, it has the following disadvantages: since the water inlet of the photobiological reaction unit at the front of the system obtains culture fluid and water, when the system is supplied and collected at the same time, the concentration of algal fluid in each unit will decrease, and The concentration of algae liquid in each unit always increases in a gradient from front to back. Since each unit is always reproduced with the original fed algae, the consequence is that the algae will degenerate and the output will also decrease; at the same time, in each feeding The contained predators have the conditions to live and reproduce in each unit for a long time, so the cycle of disinfecting the system and replacing the light-transmitting film culture bags must be shortened
