Description
Technical field
The present invention relates to the cultivation equipment of a kind of unicellular little algae.
Background technology
It is 02214168.5 that China Intellectual Property Office discloses a patent No. on March 26th, 2003, and name is called the patent documentation of the culture apparatus of unicellular algae.This device is by cultivation tank, and the nutrient solution supply that has that links with it divides device, and the water supply divides device, and air and carbonic acid gas supply divide device, and the collection of algae liquid divides device and source of artificial light to divide device to form.This technology has following shortcoming, owing to be continuous cultivating microalgae, needs a large amount of water through sterilization constantly to inject cultivation tank, and the prior art is used ultraviolet sterilizer.This Sterilizers is not high to microorganism and the protozoon killing rate that influences micro-algae propagation and growth, and mentioned microorganism that it is not killed and protozoon will breed rapidly in cultivation tank and grow.Therefore, through must clearing up completely cultivation tank after a while, along with the increase of clearing times will influence output and increase production cost.If with the chemical process sterilization, then in the sterilization tank of special use, add clorox, dioxide peroxide, added hypo again through 12～24 hours and remove chlorine residue; Perhaps adding hydrochloric acid and acid adjustment basicity in the water of sterilization tank is below the PH2, and making potential of hydrogen through repeated hydrogenation sodium oxide after 24 hours is to finish sterilizing works about PH8.This sterilising method length that takes time, it is not thorough to sterilize, and at least two complete equipments will be arranged, and in water residual chemicals also, unfavorable to both culturing microalgae; In addition, if breeding of little algae and growth in optimum temperature range, its breeding and growth rate also the maximum, but prior art is not taken measures to above-mentioned optimum temperature range, therefore, in winter during cultivating microalgae, its seawater water temperature is the end very, water cultivating microalgae output with this temperature is very low, in summer during cultivating microalgae, the water temperature of seawater is higher, and cultivation tank is subjected to the irradiation of high light in summer, its temperature can be up to 40 ℃, even need the very high salt algae of temperature also can normally numerous and growth.
Summary of the invention
The object of the invention is to provide a kind of both culturing microalgae equipment for the shortcoming that overcomes prior art, and the breeding water that is provided in its continuity breeding process can reach almost hundred-percent other microorganisms that influence both culturing microalgae of killing; The present invention can also be provided with heat radiation/heat-absorbing device in cultivation tank, its hot/cold source is arranged on outside the cultivation tank, makes algae liquid in the both culturing microalgae equipment be in the best breeding temperature range of little algae, the little algae of production that can continuous high-efficient.
The present invention can reach by following measure: a kind of both culturing microalgae equipment, comprise cultivation tank, and by the water supply that pipeline links with it, nutrient solution feeding mechanism, air supply device, carbonic acid gas feeding mechanism, algae liquor collecting device and source of artificial light; Be characterized in that described water supply is to be connected by following device to form; The water-in and the water source of working shaft link, the cooling water inlet of its water outlet and heat exchanger set links, the cooling water inlet of water heater and the cooling water outlet of heat exchanger set link, the hot water inlet of its hot water outlet and heat exchanger set links, going out the water-in of water pump and the hot water outlet of heat exchanger set links, its outlet links with the hot water inlet of temperature adjustment water tank, and a water-in of temperature adjustment water tank hot water outlet and cultivation tank links, and temperature adjustment water tank mouth cold water cycles through pump and the water source links.The present invention also has a register, and its heat radiation/heat-absorbing device is arranged in the algae liquid of cultivation tank, and its hot/cold source is positioned at outside the cultivation tank.
The present invention compared with prior art has following advantage: from described solution as can be seen, because water heater can be heated to water 85～100 ℃ of high temperature continuously, be enough to kill microorganisms all in the water and other protozoons, be heated disinfectant water and pass through heat exchanger set again continuously, at last the temperature that enters cultivation tank by the temperature adjustment water tank is adjusted into the optimum growth temp of cultivating microalgae, check through routine, the handled water of water supply of the present invention, its protozoon killing rate is 99.99～100%, and bacterial inactivation rate is 99.99～100%.Water in the cultivation tank contains protozoon and amount of bacteria is almost nil owing to enter.Therefore, can be extended down to more than half a year the pitch time of cultivation tank cleaning.When passing through heat exchanger set owing to the water that comes out from water heater again, its heat is absorbed by cold water to be heated, if heat exchanger set is three grades, the water heater Heating temperature reaches 90 ℃, then the cooling water inlet temperature of heat exchanger set is 20 ℃, and 30 ℃ of hot water outlet temperature, hot water inlet temperature are 90 ℃, cold water outlet temperature is 70 ℃, so water supply installation of the present invention can also be saved a large amount of heat energy.It can also be seen that from solution of the present invention, because heat radiation/heat-absorbing device is housed in cultivation tank, its hot/cold source is positioned at outside the cultivation tank, this improved result can make the algae liquid in the cultivation tank be in the optimum temperature range of micro-algae propagation and growth always, and the output of its little algae can obtain large increase.
