Abstract

The apparatus for dissolving gas in liquid consists of a casing with inlet and outlet arranged at both ends respectively and an adjustable pitch propeller installed in the casing. The gas and liquid pass through it while they are stirred by the propeller. It features small size, low cost and high gas-dissolving efficiency (the dissolving amount of oxygen in water at 20 deg.C and one standard at is 55 mg/l), and may be used for treating waste water or aerating beverage.

Description

Liquid air-dissolving apparatus
The present invention relates generally to a kind of wastewater treatment equipment, specifically relates to a kind of aerobiont method and handles the waste water air-dissolving apparatus.
Current, handle sanitary sewage and organic waste water and adopt the aerobiont method usually.This method needs constantly oxygen supply in disposing of sewage.Its method for supplying oxygen generally has two kinds: the one, and the air aeration method; The 2nd, pure-oxygen aeration method.The air aeration method, because the ratio (volume ratio is 20.95%) that oxygen accounts in the air is less, and the solubleness of gas in water is less again, and in the time of 20 ℃, a standard atmosphere is depressed, and the saturated meltage of oxygen in water is 9.2 mg/litre.Therefore, use a large amount of air aerations, equipment volume is big, floor space is big, investment is big, operational administrative control is complicated, efficient is low, power consumption is big, cost is high.Pure-oxygen aeration method, though have that volume is little, floor space is little, less investment, can guarantee to handle quality, produce advantages such as sludge quantity is few, the maintenance management operation is convenient and reliable, expense is low, the disposal field envrionment conditions is better, but need to adopt the sealing and circulating aerating apparatus, prevent that undissolved oxygen scatters and disappears, increase investment and management difficulty so again.
The objective of the invention is to overcome above-mentioned shortcoming, provide a kind of simple in structure, volume is little, easy to operate, working cost is low, the liquid air-dissolving apparatus of the meltage of oxygen in water be can improve greatly, thereby the processing quality and the processing efficiency of life and organic waste water improved.
Liquid air-dissolving apparatus of the present invention comprises a housing that has import and export.Described housing inner support a rotating variable-pitch screw blade wheel.The shape of described variable-pitch screw blade wheel, the equation of locus of the edge of its blade from entrance end to exit end is:
X i=a·Cosθ i
Y i=a·Sinθ i
Z i=b·θ m i
In the formula: X i, Y i, Z iThe coordinate of arbitrfary point ,-impeller vane edge;
The a-impeller radius;
θ iThe windup-degree of-screw-blade arbitrfary point;
M-variable-pitch propeller coefficient, can be between 0<m<1 any point;
B-(L)/(2 π m) in the formula: L is an impeller length
Described import and export is arranged in the two ends of described housing along the axial direction due of described variable-pitch screw blade wheel, and described import communicates with liquid gas mixing tube, and described outlet communicates with molten gas fluid hose.
Liquid air-dissolving apparatus of the present invention has only several parts to form, it is simple in structure, volume is little, cheap, maintenance management convenient, molten gas efficient height, in the time of 20 ℃, depresses at a standard atmosphere, can make the meltage of oxygen in water reach 55 mg/litre.This device can be directly used in the wastewater treatment oxygenation or utilize it to produce that water containing high dissolved oxygen removes to handle sanitary sewage and organic waste water, purifying contaminated water system and boiler flue gas desulfurization, also can be used for the beverage aerating, molten medicine mixes stirring, industrial aerating fermentation etc.
Other details of liquid air-dissolving apparatus of the present invention can be cheer and bright by reading the embodiment hereinafter encyclopaedize in conjunction with the accompanying drawings, wherein:
Fig. 1 is the structural representation of liquid air-dissolving apparatus of the present invention;
Fig. 2 is a liquid air-dissolving apparatus blade wheel structure synoptic diagram of the present invention;
Fig. 3 is the vertical view of liquid air-dissolving apparatus impeller of the present invention;
Fig. 4 is a liquid air-dissolving apparatus impeller bearing seat structure synoptic diagram of the present invention;
Fig. 5 is the application system figure of liquid air-dissolving apparatus of the present invention.
With reference to Fig. 1-Fig. 4.In the columniform housing 1 of liquid air-dissolving apparatus of the present invention variable-pitch screw blade wheel 2 is housed.Displacement impeller 2 is made for 360 ° around central shaft 3 distortions by a flat board.Pitch liquid air current flow direction is vertically successively decreased, and the shape of its impeller 2 blade edges in axial direction equation of locus from bottom to up is:
X i=a·Cosθ i
Y i=a·Sinθ i
Z i=b·θ m i
In the formula: X i, Y i, Z iThe coordinate of arbitrfary point ,-impeller vane edge;
The a-impeller radius;
θ iThe windup-degree of-screw-blade arbitrfary point;
M-variable-pitch propeller coefficient, can be between 0<m<1 any point;
B-(L)/(2 π m) in the formula: L is an impeller length
The b value is big, processing difficulties, but molten gas efficient height, and volume is big; The b value is little, handling ease, but molten gas efficient is low, and volume is little.
Bearing spider 4 is equipped with at the two ends of housing 1, central shaft 3 rotating being bearing on the bearing support 4 of impeller 2.Link together by some (being illustrated as 3) spokes between the outer shroud 42 of bearing support 4 and the bearing 41, so that between spoke, form the fluid channel.The outer side of bearing support 4 links to each other with molten gas fluid hose 13 with liquid gas mixing tube 12 respectively by ring flange 6.
With reference to Fig. 5.Fig. 5 is the system diagram that liquid air-dissolving apparatus of the present invention is used.Oxygen cylinder 7 is by reducing valve 8, connects ejector 11 through tracheae 9 and control valve 10 and communicates with liquid gas mixing tube 12; Water pipe 14 connects ejector 11 through control valve 13 and joins with liquid gas mixing tube 12.The inlet of liquid air-dissolving apparatus links to each other with liquid gas mixing tube 12.The outlet of liquid air-dissolving apparatus links to each other with molten gas fluid hose 13, and by-pass valve control 14 is housed on it.The axle 3 of variable-pitch screw blade wheel 2 is driven by motor 5.
During work, open valve 13 and oxygen cylinder reducing valve 8 and by-pass valve control 10.Water enters liquid air-dissolving apparatus through liquid gas mixing tube 12 by ejector 11 through water pipe 14 after oxygen tentatively mixes.Variable-pitch screw blade wheel 2 in the air-dissolving apparatus is by electric motor 5 driven rotary, water and oxygen mix fluid form complicated liquid air-flow under the drive of variable-pitch screw blade wheel 2, in housing 1, produce radially and axial big pressure gradient, enlarge and transmit the interface, complex flow such as turbulization and eddy current state makes gas become micro bubble less than 0.2mm, causes gas over-saturation dissolving, the big manyfold of meltage under the comparable standard state, and oxygen is remained on be difficult in the water discharging.Over-saturation dissolved oxygen water enters dissolved air water case 15 for using through valve 14 and molten gas fluid hose 13 again.
This device can be directly used in wastewater treatment, the purifying contaminated water system, and the beverage aerating, molten medicine mixes stirring, aerobic fermentation etc.And available adjustment rotating speed is adjusted the oxygenation meltage.
