Abstract
The utility model relates to a water body external circulation membrane type oxygen enhancing machine which is formed by that a membrane oxygenator is used as a key part, and a filter, a water pipe, a water valve, an air pipe and an air valve are matched for assembly. The membrane oxygenator is composed of a cylinder body and a plurality of pieces of water drainage hollow fibre installed in the cylinder body, both ends of the hollow fibre are provided with glue sealing areas, and a water inlet, a water outlet, an air inlet, and an air outlet are arranged on the cylinder body. Anoxic water carries out oxygen exchange in the membrane oxygenator to realize oxygenation and then returns back to a culture pond. The oxygen enhancing machine not noy has a favorable effect of oxygen enhancement to ensure that the dissolved oxygen amount of sea water reaches and exceeds seven mg/l, but also has the advantages of high efficiency and low energy consumption.
Description
The utility model belongs to the oxygen-increasing device that usefulness is cultured in aquatic products industry.
In the aquatic products industrialized aquaculture, because the aquatic products density in the unit of water body is bigger, for the dissolved oxygen amount that guarantees that the aquatic products normal growth is required, must constantly oxygenation in water body.Particularly marine product is cultured, and the oxygenation of seawater water body is even more important, because the chlorinity of sea water height, natural dissolved oxygen can force rate fresh water low (be about fresh water 85%) if do not take the oxygenation measure, certainly will influence growing and survival rate of marine product.
About oxygenation, now the aerator that uses has kind surplus vane type, Waterwheel-type, jetting type, water burst formula, biological rotating disk (tube) formula, the Water etc. 20, with regard to its principle classification, mainly contains three classes, i.e. inflatable, water surface stirring-type, the gravity formula that drops.Inflatable is called diffusion type again, and being the oxygen that utilizes artificial system is released to diameter greater than 1 millimeter bubble by the device of air that looses, and oxygen dissolves in water body in the uphill process of bubble; This kind mode is because the diameter of bubble is bigger, so mass transfer area is limited, solute effect is undesirable, and oxygen utilization rate is low, and the artificial manufacturing cost of oxygen is higher.Water surface stirring-type is called again and stirs ability of swimming, is to rely on machine power to increase the contact area of the water and air of culturing pool surface, thereby makes airborne oxygen soluble in water; This kind mode only occurs in the top layer of water owing to stirring, thus the dissolved oxygen amount in the superficial water is increased, and the oxygenation that can not solve middle level, lower floor, bottom water, in addition, energy consumption greatly also is a shortcoming.Gravity drop formula is to utilize the gravity drop, the spray that splashes is contacted with atmosphere, thereby realize oxygenation, and not only oxygenation efficient of this mode is low, and noise is big, influences the growth of aquatic products.
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of oxygenation efficient height, energy consumption is low, noise is little, the membrane type aerator of economic operating cost, to satisfy the needs of aquaculture.
The purpose of this utility model is achieved in that and has designed a kind of membrane oxygenator, it is made up of cylindrical shell and some hydrophobic doughnuts being loaded in the cylindrical shell, doughnut can be selected doughnuts such as polypropylene, polyether sulfone for use, there is the Jiao Feng district at the doughnut two ends, and cylindrical shell is provided with water inlet, delivery port and air inlet, gas outlet.The gap that is positioned at two ends between each root doughnut is filled in the Jiao Feng district, the anoxic water that enters cylindrical shell by water inlet is flowed between each hollow fiber conduit, enter the compressed air of cylindrical shell or oxygen flows and enter between pipe from tube wall and to carry out the oxygen exchange with water by air inlet in each hollow fiber conduit, thereby realize oxygenation the anoxic water body.
Water body outer circulation membrane type aerator provided by the utility model is to be core component with above-mentioned membrane oxygenator, and is equipped with filter, water pipe and tracheae and assembles.Water inlet on filter and the membrane oxygenator cylindrical shell is connected to form into water loop by water pipe, and the delivery port on the membrane oxygenator cylindrical shell communicates with aquaculture pond by the water pipe connection, and water pipe is provided with water valve; Air inlet on the membrane oxygenator cylindrical shell is by tracheae and compressed air source or source of oxygen connection formation air inlet loop, and the gas outlet on the membrane oxygenator cylindrical shell communicates with atmosphere by tracheae, and tracheae is provided with air valve.The number of membrane oxygenator, according to the size decision in aquaculture pond, the aquaculture pond is big more, and the number of membrane oxygenator is many more, and when membrane oxygenator was two or more, compound mode preferably adopted parallel connection, the height of oxygenation efficient like this.
Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.
Fig. 1 is a kind of structure chart of membrane oxygenator;
Fig. 2 is a kind of structure chart of water body outer circulation membrane type aerator.
Embodiment:
The structure of the water body outer circulation membrane type aerator in the present embodiment as shown in Figure 2, its member has membrane oxygenator 8, filter 13, water pipe 10, water valve 11, tracheae 9 and air valve 12.The structure of membrane oxygenator as shown in Figure 1, form by cylindrical shell 1 and many root polypropylenes doughnut 2, the doughnut two ends form Jiao Feng district 3 by epoxy resin under centrifugal action, cylindrical shell 1 is a thin cylinder, its top is provided with gas outlet 4, its bottom is provided with air inlet 6, and its upper end sidewall is provided with water inlet 5, its lower end sidewall is provided with delivery port 7.The quantity of membrane oxygenator is 5, adopts the parallel way combination.Water pipe is communicated with filter with the water inlet of each membrane oxygenator, form the water inlet loop, and water pipe links to each other with the delivery port of each membrane oxygenator and joins with the aquaculture pond, the water after the oxygenation is sent into cultured the pond, and water valve is separately positioned on into water and goes out in the water loop.Tracheae is communicated with the air inlet of each membrane oxygenator respectively with the gas outlet, form the air inlet loop and go out air circuit, and air valve is arranged on the air inlet loop and goes out on the air circuit.
During oxygenation, send into filter with the water extraction that immersible pump will be cultured in the pond, the water after the filtration enters membrane oxygenator, and compressed air or oxygen also enter membrane oxygenator simultaneously, the exchange of water and gas reverse flow in membrane oxygenator carrying out oxygen, the Chi Shui behind the oxygenate is sent back to cultures the pond.So constantly circulation can be satisfied the demand of aquatic products to oxygen.
The utlity model has following advantage:
1. realize oxygenation by membrane oxygenator, efficient increases substantially, and compares oxygenation efficient with inflatable oxygenation Can improve 5～10 times.
2. energy consumption is low, compares with stirring-type oxygenation, and is capable of reducing energy consumption more than 50%.
3. oxygenation effect is good, and the seawater dissolved oxygen amount can reach and surpass 7mg/l.
4. use this aerator, generally adopt oxygenating air, compare, can reduce cost 2/3rds at least with adopting oxygen oxygenation.
5. have oxygenation, toxin expelling dual-use function concurrently.
6. adopt water body outer circulation oxygenation, not only noise is little, and can make the water of culturing each depth layer in the pond all reach the oxygen content requirement.
