Specific embodiment
Below by attached drawing, the present invention is described in detail.
The present invention provides a kind of concatenation type mixing wastewater with air propulsion device, including multiple admission lines 1, each air inlet
1 tail portion of pipeline is all connected with 1 gas spout 3, further includes water inlet line 5, tail portion spout 4, the gas spout 3 is circle
Circulating line, and lower end seals, the top outer diameter of the tail portion of the admission line 1 from the circular ring shape pipeline of gas spout 3
Tube wall penetrates and coupling part is all close connection from the sucking air of admission line 1, the gas-vapor mix in water inlet line 5, then
The propulsive thrust that the injection of spout 4 is formed in tail portion just constitutes the major impetus source of ship advance.
Admission line of the present invention is 3.
The admission line 1 is vertically placed in hull, and the upper end of the admission line 1 is worn perpendicular to deck and upwards
Cross deck.
As shown in Figure 1, the admission line 1 is divided to for two parts wide at the top and narrow at the bottom, top outer diameter Guan Weikuan pipe, lower outer diameter
Pipe is narrow pipe, is closely connect at narrow pipe and wide interface tube, the entirety after the wide pipe of admission line 1 is closely connect with narrow pipe is put vertically
It is placed in hull；Allowing more gases when 2 high speed rotation of turbine, leniently pipe nozzle is inhaled into, and being inhaled into gas, leniently pipe enters
When the lesser narrow pipe of caliber, gas pressure increases, and is finally quickly sprayed with higher pressure from the gas spout 3 of narrow pipe tail portion；
And the power and gas that ship advance is given due to sucking thrust while width pipe sucking gas are after narrow pipe is pressurized
It sprays from gas spout high pressure and is sufficiently merged with water flow, finally just constituted from the propulsive thrust that the injection of ship tail portion spout 4 is formed
The major impetus source that ship advances.
The wide pipe is perpendicular to deck and is upward through deck, and the part higher than deck passes through right-angle elbow pipe at nozzle
Interface connects the round tube for being parallel to captain direction, and nozzle is towards fore direction, and pipe diameter is identical as wide pipe diameter, after
One air inlet is higher by the height of 1/2 wide pipe diameter than previous air inlet, and nozzle is closely connect with nozzle junction, this
Sample design breaks down primarily to preventing rainy day rainwater from causing turbine to be intake from air inlet inflow, reduces previous when air-breathing
Air inlet openings inhibition caused by the latter air inlet, and be due to sucking thrust while sucking gas
Ship provides a part of onward impulse.
The water inlet line 5 is also simultaneously mixing wastewater with air pipeline, it is divided into multistage, two-by-two with the circle on gas spout
Close connection before and after circulating line inner wall, is placed on the straight line where the tailing axle of traditional propeller and assembled water inlet line
Entire hull is run through in front and back；Caliber is rearwardly gradually increased by small by this one end of water inlet, when close to tail portion spout rapidly by
It is reduced to greatly consistent with 4 pipe diameter size of tail portion spout；Water inlet line 5 in this way design can it is more convenient with 3 groups of gas spout
It fills and replaces and alleviate air-water mixture to the pressure of tube wall, to guarantee that air-water mixture at the uniform velocity flows in water inlet line
It is dynamic.
As shown in Figure 3 and Figure 4, the internal diameter of the circular ring shape pipeline of the gas spout 3, which closes, is embedded with multiple small nozzles on tube wall,
Multiple small nozzles be spirally distributed along even tube wall and the angle of each small nozzle along tube wall circumference tangentially inwardly
3 degree of inclination.The design in this way of gas spout 3 can allow gas to spray simultaneously from each height of water inlet line 5 and form helical form height
Pressure gas stream carries out more fully air water with the water flow in water inlet line 5 and merges, while improving mixing wastewater with air in water inlet line 5
The speed that object integrally at the uniform velocity flows.
The small nozzle is 6.
When ship advances, water flow is flowed into from 5 nozzle of water inlet line of place foremost part of ship sprays with from each gas spout 3
High pressure gas out at the uniform velocity flow in water inlet line 5 after adequately merging, most fast through pressure when the spout of ship tail portion afterwards
Speed increases to which high-voltage high-speed sprays.Ship is controlled by 6 left and right adjusting of rudder blade after air-water mixture is sprayed from tail portion spout 4
The direction that oceangoing ship advances.
Although the present invention has been described by way of example and in terms of the preferred embodiments, they be not it is for the purpose of limiting the invention, it is any ripe
This those skilled in the art is practised, without departing from the spirit and scope of the invention, can make various changes or retouch from working as, therefore guarantor of the invention
Shield range should be subject to what claims hereof protection scope was defined.
