Description
One, technical field
The utility model relates to a kind of novel micro bubble generation device, specifically belongs to a kind of air supporting micro bubble generation device.
Two, background technology
The air supporting method is disposed of sewage or ore etc., is by the suspended particulates in the microbubble adsorptive liquid, floats then to fluid surface, thereby carries out isolating a kind of method.Therefore micro bubble generation device is that the air supporting method is disposed of sewage or the key of ore.Traditional air-floating apparatus has air soluble method and electrolytic process, and these methods all exist shortcomings such as equipment complexity, working cost height.Air soluble method for example, it is made of dissolving, air compressor, force (forcing) pump, Controlling System and outgas whipping appts etc.At first inject clear water and air during work in dissolving, under certain pressure, the part air dissolves in the water, forms dissolved air water.Dissolved air water is drained into the air flotation pool bottom by the outgas device, and decompression back air disengages the micro-bubble come-up and produces air flotation effect in water.This method is the device systems complexity not only, equipment and working cost height, but also need to consume in addition clear water.In addition, also have at present to adopt and penetrate suction method air-floating apparatus, it is to utilize to penetrate to inhale the normal direction dissolving and inject clear water and air, makes it the mixed dissolved air water that forms.Though this device has saved air compressor machine, but still there is the device structure complexity, the energy consumption height, the working cost height needs to consume in addition shortcomings such as clear water.
Three, summary of the invention
Task of the present utility model is: provide a kind of new-type air-floatation micro bubble generation device, so that it is simple in structure, energy-conservation, economize on water, be easy to make and promote.
For finishing above-mentioned task, the technical solution of the utility model is as follows:
A kind of new-type air-floatation micro bubble generation device mainly is made of water pump and special nozzle.Special nozzle is made up of nozzle body, damping cutting and inlet union.Be shaped on negative pressure cavity and outlet plenum in the nozzle body.Negative pressure cavity and outlet plenum are communicated with by the larynx hole.Negative pressure cavity is connected with inlet union.Inlet union is shaped on pod apertures.Inlet union is connected with pump.Pump is communicated with negative pressure cavity by pod apertures.The negative pressure cavity side is shaped on and is attached thereto logical air inlet port, and air inlet port is connected with air intake branch, and the air intake branch the other end communicates with atmosphere, and air intake branch is communicated with atmosphere by air inlet port with negative pressure cavity like this.Damping cutting is combined by top cylinder and bottom cone, is provided with fillet surface between bottom cone and top cylinder.Damping cutting is contained in the nozzle body outlet plenum, and the top cylinder of damping cutting has certain spacing between the two outside the outlet of outlet plenum top and corresponding with this outlet.The awl point of the bottom cone of damping cutting is corresponding with the larynx hole between outlet plenum and negative pressure cavity; The top outside diameter of bottom cone is less than the outlet plenum internal diameter, between the big end in the top of outlet plenum top export department and bottom cone, be provided with contact, by this contact damping cutting is connected as a single entity with nozzle body, this contact is circumferentially uniform along the cross section of bottom cone and outlet plenum top export department, thereby makes and form the ring shaped axial passage between per two contacts between bottom cone outer side and outlet plenum top export department medial surface.
All less than the internal diameter and the volume of outlet plenum, the internal diameter of the pod apertures on the inlet union is less than the internal diameter in the time hole that is communicated with negative pressure cavity and outlet plenum built in the internal diameter of the intravital negative pressure cavity of nozzle and volume.
The utility model is used through experiment and examination, has following advantage and effect:
1, this device can produce a large amount of microbubbles effectively, and the efficient height can satisfy the air-float technology needs.
This air supporting micro bubble generation device is to throw in air flotation pool in use.When submersible pump the sewage in the air flotation pool, pod apertures by inlet union pumps into the nozzle body negative pressure cavity rapidly, when injecting outlet plenum rapidly by the larynx hole then, owing to penetrate the principle of suction, form negative pressure at negative pressure cavity, thereby air is inhaled into negative pressure cavity through air intake branch, air inlet port and sewage is mixed.What inject outlet plenum like this from the larynx hole is gassiness sewage.Because the awl point of damping cutting is corresponding with the larynx hole and point to the larynx hole, therefore the gassiness current of injecting at a high speed are changed tapered stratiform by pencil.Because the existence of resistance gradient makes that each laminar flow speed of current is different, thereby make the intravital bubble of stream constantly be cut, become a large amount of micro-bubbles, the fluid that contains these micro-bubbles is connected ring shaped axial passage and the fillet surface that forms between contact via the big end in cone top, bottom with outlet plenum top export department, scatter to the air flotation pool bottom, produce air flotation effect.Through certain the slaughterhouse's sewage disposal test result that adopts this device is shown that under the situation that does not add any medicament, the COD clearance can reach 40%, the clearance of grease and oil in water emulsion reaches more than 95%.
2, the utility model system device is simple in structure, does not need air compressor machine, dissolving, Controlling System etc., only needs the water pump or the submersible pump of certain lift to get final product, thereby makes device structure simple, and manufacturing expense reduces greatly.Compare with conventional air-floating apparatus, the utility model facility investment only is the latter's 1/3.
3, equipment is installed and is simple to operate, easy to maintenance.
4, energy-conservation, its energy consumption only is 2/3 of traditional air supporting method, and noiselessness.
5, water saving, whole technological process does not need to consume in addition clear water.
6, working cost is low, is easy to popularize.
