Description

A kind of microbubble and heat joint damping device
Technical field
The utility model is related to microbubble and joint damping device is heated, belongs to ship domain.
Background technology
Compressed air is inputted to hull bottom using wind turbine, due to the effect of flow, realizes and forms bubble behind disconnected grade, to Realize ship air lubrication drag reduction.In addition, being heated to microbubble, microbubble is heated with the water that flow flows through, reduces this part The coefficient of frictional resistance of water realizes that ship heats drag reduction.There was only bubble drag-reduction in existing ship, without increasing to bubble Warm drag reduction.
Utility model content
Purpose of utility model:In order to overcome the deficiencies in the prior art, the utility model provide a kind of microbubble and Joint damping device is heated, bubble is preheated using discarded, reaches joint drag-reduction effect, improves drag reduction efficiency.
Technical solution:In order to solve the above technical problems, a kind of microbubble of the utility model and joint damping device is heated, Include micro bubble generation device and main auxiliary machine in cabin, the bubble and exhaust gas that micro bubble generation device and main auxiliary machine generate Transported by concentric pipe, bubble transported in concentric pipe inner tube, exhaust gas is transported in concentric pipe outer tube, alow on set There are several gas vents, gas vent to be connect with the connecting tube that concentric pipe inner tube is connected to, the exhaust gas discharge in concentric pipe outer tube Outboard.
Preferably, being welded with reinforcement plate at the gas vent.
Preferably, the gas vent is arranged in captain direction away from bowCaptain andAt captain.
Preferably, being provided with back-flow preventer at the gas vent.
In the present invention, micro bubble generation device is mounted in cabin, the exhaust gas that can generate main auxiliary machine Microbubble is heated immediately, improves heating duration;Two come do not have to deliberately the design phase reserve cabin installation microbubble fill It sets, avoids the dischargeable capacity for reducing the commercial part of ship because of additional equipment.Heating mechanism portion is carried out using concentric round pipe Gas is conveyed, Outer Tube conveys exhaust gas, and interior conduit conveys microbubble, on the one hand can fully be heated to microbubble, reduces heat Scatter and disappear;On the other hand gas partitions can be heated, when discharge is no longer detached.Heating device is arranged in double Between the inner bottom plating and Outer Bottom Plating of layer bottom ship, away from Outer Bottom Plating inner surface 30cm;Open-bottom vessel is arranged in from Outer Bottom Plating inner surface 30cm. Feature so arranged is on the one hand will not to reduce the commercial part dischargeable capacity of ship;On the other hand ship center of gravity can be reduced, Improve vessel stability.Waterproof backflow device is added at gas vent, stop port in ship, riding at anchor of being out of order etc. whens, utilize Waterproof backflow device blocks gas vent, prevents the water outside hull from being flowed back into ship by gas vent.Gas vent is along the beam point Cloth direction is conducive to microbubble stepless action face outside hull perpendicular to captain direction.
Advantageous effect:The microbubble of the utility model and joint damping device is heated, had the following advantages:
It is heated 1. being combined in the technical foundation of Friction Reduction by Micro-bubbles, reaches joint drag-reduction effect, improve drag reduction efficiency.
2. carrying out partition board heating to microbubble using the exhaust gas that main auxiliary machine generates, waste gas residual heat is made full use of, improves the energy Utilization ratio.
3. exhaust gas and microbubble do not have Hybrid Heating, but concentric pipe partition board is used to heat, hull is discharged in two kinds of gases Before, microbubble conveyance conduit is isolated into waste gas delivery pipeline road, exhaust gas is discharged in air, and microbubble passes through air-out apparatus It is discharged in the water of hull Outer Bottom Plating, avoids to be discharged in water together with exhaust gas and microbubble and cause water pollution.
4. concentric disk spacer heating conveys exhaust gas from Outer Tube, microbubble is conveyed from interior conduit.One can increase to pair The heating surface (area) (HS of microbubble improves the efficiency of heating surface;Two can reduce microbubble in transmission process heat scatter and disappear.
5. microbubble air-out apparatus, on the exhaust hole site of hull Outer Bottom Plating, installation is welded with reinforcement plate, to improve Make the structural strength of outside plate strength reduction at this because opening up gas vent.
6. along captain direction away from bowCaptain andMicrobubble gas vent is set at captain, away from bowAt captain The microbubble of gas vent discharge acts on gas vent along stern direction extremelyThe hull of vent section at captain;Away from bow The microbubble of gas vent discharge at captain acts on hull of the gas vent after stern direction.

Specific implementation mode
Shown in Fig. 1 to Fig. 5, a kind of microbubble of the utility model and joint damping device is heated, including is located in cabin Micro bubble generation device 2 and main auxiliary machine 1, the bubble and exhaust gas that micro bubble generation device 2 and main auxiliary machine 1 generate pass through concentric circles Pipe transports, and transports bubble in concentric pipe inner tube 4, exhaust gas is transported in concentric pipe outer tube 5, is alow equipped with several Gas vent 3, gas vent 3 are connect with the connecting tube that concentric pipe inner tube 4 is connected to, and outboard is discharged in the exhaust gas in concentric pipe outer tube 5, Reinforcement plate 7 is welded at the gas vent 3, the gas vent 3 is arranged in captain direction away from bowCaptain andAt captain, It is provided with back-flow preventer at the gas vent 3.
In the present invention, back-flow preventer includes non-return plate 8, back cover 9 and control device, and back cover 9 is installed Alow on outside plate 6, gas vent 3 is located in back cover 9, and reinforcement plate 7 is equipped at gas vent 3, pacifies in reinforcement plate 7 Equipped with non-return plate 8, non-return plate 8 is connect with control structure, drives non-return plate 8 to move by control structure, control structure Can be the linear motor with microcontroller, by the movement of the mobile drive non-return plate 8 of linear motor, to pass through non-return 8 closed grate hole 3 of plate.
When the utility model is used, ship is in the process of moving, by running micro bubble generation device 2, open simultaneously Waterproof backflow device, by the microbubble of generation by the concentric disk spacer heating pipe of pipeline to heating device, by adding Ship hull plate is discharged by gas vent 3 in the microbubble of heat, the flow that microbubble is moved backward with opposite ship traveling process to After be dispersed in ship Outer Bottom Plating, outer backplate surface formed one layer of microbubble film;Simultaneously because of buoyancy, microbubble is along ship side Outside plate forms one layer of microbubble film to surface motions, on the quarter outer plate surfaces, realizes Friction Reduction by Micro-bubbles.In addition, microbubble is not The local ship hull plate that can be spread can increase, this part water because microbubble is by heating in the temperature for the water that it is flowed through It can be contacted with the local ship hull plate for not spreading microbubble, realization heats drag reduction.Exhaust gas then by pipeline, is discharged into air. It in ship entry or is out of order, accident occurs etc., when needing riding at anchor, by micro bubble generation device 2 and waterproof backflow device It simultaneously closes off, avoids fuel of the waste microbubble without effect when.
The above is only the preferred embodiment of the utility model, it should be pointed out that:For the common skill of the art For art personnel, without departing from the principle of this utility model, several improvements and modifications can also be made, these improve and Retouching also should be regarded as the scope of protection of the utility model.
