Abstract
The invention provides a gas exchange device for water circulating aquaculture, and relates to the field of bioengineering. The gas exchange device for water circulating aquaculture is particularly designed for an oxygen enrichment link of a water treatment process. Land-based factory-like constant temperature water circulating aquaculture is the optimal mode for facility fishery and has the advantages of saving energy, being environmentally friendly, avoiding red tides, typhoons, high temperatures and other natural disasters, realizing stable yield, shortening a culture cycle at a constant temperature, realizing high concentration under the condition of oxygen enrichment, and realizing high yield. A negative pressure deaeration and compression aeration technical device is characterized in that the oxygen content of backwater circulated in a cultivation system is reduced due to biological and chemical oxygen consumption; biological excretion is degraded biochemically, so that the concentration of ammonia nitrogen, carbon dioxide, hydrogen sulfide and nitrous acid is increased; the PH value rises and directly affects the solubility of secondary oxygenation and water treatment effects. The gas exchange device is composed of a degassing tower, a vacuum pump, an oxygen supplier and an aeration tower. The utilization rate of oxygen is high, the solubility of oxygen can reach more than 15-25 milligrams per liter, and oxygen-enriched water is mixed with circulating water and modulated so as to meet the optimal oxygen requirement of cultivated bionts.
Description
A kind of gas exchange device of circulating water cultivation relates to bioengineering field, aim at the oxygenation link design of water treatment, the cultivation of continental rise batch production thermostatical circulating water is the optimal mode of facility fishery, advantage with energy-saving and environmental protection, avoid the natural calamities such as red tide, typhoon, high temperature, realize stable yields, the constant temperature Shortening culturing period, oxygen enrichment ability high density, realize high yield.The present invention specializes in the auxiliary facility of industrial circulating water cultivating.
A kind of negative pressure degasification with the feature of pressurization inflation technique device is: through the backwater of cultivating system circulation, because of biological and chemical oxygen consumption, oxygen-content reduction, biological excretion, increase ammonia nitrogen, carbonic acid gas, hydrogen sulphide, nitrous acid concentration biochemical the decomposition, pH value rises, and directly affects the solvability of two-pass aerating, and the water treatment effect.
Gas exchange device of the present invention is by degassing tower, vavuum pump, filler, water leg, the oxygen supply system, high-speed centrifugal pump, sudden and violent gas tower, the discharge pressure control valve forms, schematic diagram is shown in the gas exchange device technological process, circulating backwater is through pipeline under the effect in negative pressure, 1. self-priming enters degassing tower, through the Rotary Water distributor 2., arrive multilayer corrugated plate filler 3., long-pending to increase water film surface, at vavuum pump, under effect 4., partial pressure makes the pernicious gas discharge of fully volatilizing, reach degassed purpose, 6. water leg de aerated water 5. enters high-speed centrifugal pump through pipeline, 7. input the 95% above pure oxygen through molecular sieve pure oxygen machine output at the pump water pipe place that advances, pure oxygen and water are in the high-speed stirred of impeller, under the effect of shearing, fully mix, output milky gas-water mixture, enter sudden and violent gas tower 8., 9. the water outlet pressure regulator valve keeps 1kg/cm
2pressure, in the process that water rises with gas in tower, fully dissolve, greatly improved the availability of oxygen and the dissolved oxygen amount of water, can be up to more than 15～25mg/L.
The accompanying drawing explanation
Accompanying drawing: a kind of gas exchange device schematic diagram of circulating water cultivation
1. degassing tower, 2. through the Rotary Water distributor, 3. arrive multilayer corrugated plate filler, 4. 5. water leg of vavuum pump
6. 7. 8. sudden and violent gas tower, 9. water outlet pressure regulator valve of water inlet pipe place of centrifugal pump
Heavy-oxygen-enriched water mixes with cycle water through pipeline, is modulated to the oxygen demand of aquaculture organism the best.
