Further include a mosquito-repellent incense coil pipe, is by a center of circle by a round tube in disk annular in shape from inside to outside in same plane
Around or round tube coil in the shape of a spiral from bottom to top along an axis；The import of gas-liquid mixed media chamber is leaned on coiling round tube annular in shape
The round tube port of nearly the center point or the round tube lower port coiled in the shape of a spiral are connected.
Vertical plate is 2 or more, vertical plate upper surface with gas-liquid mixed media chamber upper wall surface is closed amplexiforms or connect,
Vertical plate lower end surface with lateral partitions upper surface is closed amplexiforms or connect, one side end face of vertical plate and gas-liquid mixed media
One side surface of chamber side wall surface or another vertical plate is closed to be amplexiformed or connects, and labyrinth type serpentine channel is formed.
It is equipped with heated base in solution cavity bottom, is equipped with electrical heating elements in heated base.
1. mosquito-repellent incense coil pipe import of the present invention connects with fuel cell heat sink outlet, gas-liquid mixed media is logical in mosquito-repellent incense coil pipe
Road makes rotating motion, and the sinking speed of water droplet isAnd gravity settling velocity isThe sedimentation acceleration of water droplet isGravitational settling acceleration is g, the sedimentation of water droplet in mosquito-repellent incense coil pipe
Speed is more order of magnitude greater than gravity settling velocity, and the sedimentation acceleration ratio gravitational settling acceleration of water droplet is big by two in mosquito-repellent incense coil pipe
A order of magnitude, therefore the separative efficiency of mosquito-repellent incense coil pipe is higher, required settlement space is smaller.
2. mosquito-repellent incense coil outlets are that the import of gas-liquid mixed media chamber connects with the water recycling box upper layer of rear end, gas-liquid is entered
The drop particle diameter of blending agent chamber is larger, and droplet collision labyrinth type serpentine channel is turned back place, is slipped to along wall surface towards solution cavity
Down going channel, realize effective recycling of water.
3. water recycling box upper layer is that gas-liquid mixed media cavity wall pastes polydimethylsiloxanefilm film or other resistance to 80 degree
The hydrophobic material of high temperature, this is conducive to water droplet and slides along wall surface, improves water recovery efficiency.Separator main body structure is with polyethers acyl
Imines or the engineering plastics of other methanol tolerants corrosion are raw material, guarantee the durability and reliability that water segregator uses.
4. the methanol solution of pile anode export is passed through lower layer's solution cavity, Way in is parallel to solution cavity plane, avoids
Impact for liquid level of solution, setting export pipeline extend to minimum liquid level or less and solution are sucked out.
5. gas-liquid mixed media chamber height is unsuitable too low, otherwise sectional area is too small can make gas flow rate too fast, be unfavorable for liquid
The sedimentation of drop；Methanol solution chamber height is unsuitable too low, and otherwise methanol solution chamber air pressure fluctuation easily causes methanol solution to overflow in gas-liquid
Blending agent chamber.
6. air pressure connection interface is arranged in gas-liquid mixed media chamber and solution cavity, for balancing pressure.Gas-liquid mixed media chamber
It will cause solution with solution cavity pressure imbalance to overflow in gas-liquid mixed media chamber.
7. heated base is arranged in water recycling box bottom end, it is used for heating methanol solution, heating function to be switched in fuel cell
When use, realize fuel cell quick start function.
Beneficial effects of the present invention are as follows:
1. separating effect of the invention have passed through the simulation analysis verifying of Fluid Mechanics Computation method, water droplet is in mosquito-repellent incense coil pipe
Inside move in a circle, generate force of gravity and settle big 400 times of principle of sedimentation acceleration, analog result as shown in figure 4, liquid water by
In the outer diameter zone flowing for acting on pipeline of centrifugal force, gas-liquid separation effect is good.
2. the emulation that the motion state of water recycling box gas-liquid mixed media of the invention have passed through Fluid Mechanics Computation method
Analysis verifying, such as Fig. 5, gas-liquid mixed media cooling gas pass through snakelike chamber, hit wall surface, speed at the serpentine channel place of turning back
