The air channel N+ I of inward flange arrangement.The inlet and outlet direction in each air channel of air channel group is consistent, and the entrance in air channel I is positioned at annular
The most marginal position of roundabout barrier air channel import, the entrance in air channel II than air channel I entrance closer to the roundabout barrier wind of annular
Road import center, the like.It is arranged so as to ensure that each air channel length in the group of air channel is approximate, ensures from the roundabout barrier of annular
The import in air channel enters the gas of air channel group often intimate identical distance and final almost simultaneously from the roundabout barrier air channel of annular
Outlet comes out, and avoids producing pressure differential, while is arranged so as to ensure that the total length of air channel group reaches most long, such a arrangement recovery effect
Fruit is best, and condensation effect is optimal.Air channel is curved-surface structure, and what chromium mist will not be straight when passing through with the wind in air channel passes through air channel,
But can in the side wall of air channel impact several times, a similar process reflected repeatedly, and cause route of the chromium mist in air channel again
It is secondary to be extended, while the width in each air channel is 2~12mm, air channel width can neither too greatly can not be too small, Tai great rear center
Chromium mist can not be contacted with side wall, it is too small to form windage, influence coagulation result.Each air channel in the group of air channel is adjacent by two
Curved slab besieged city, the board slot that thickness matches with curved surface plate thickness is provided with lower cover 3, curved slab is inserted in board slot.Together
When the adjustment of adaptability should be done to the material of curved slab according to the liquid mist composition of recovery.Curved slab can be titanium when reclaiming chromium mist
The various materials such as plate, PVC board, preferred thickness are 0.3mm Titanium boards, and titanium plate is more frivolous, reduce space-consuming, arrange to greatest extent
The more air channels of cloth, condensation efficiency are higher.It is hydrophilic can preferably anti-corrosion, frosted, fold, blistering and coating to be carried out to curved slab
The surface treatment of lipophile layer, to improve absorption and interdiction capability.
The polywater mouth of a river 8 is provided with the lower cover 3 of shell 1, the polywater mouth of a river 8 is relative with the roundabout barrier ducting outlet of annular,
The setting at the polywater mouth of a river 8 prevents the wind that gas outlet 4 comes out from bringing the water droplet that chromium mist condenses into the device of next stage into, ensures chromium
Mist condensing water droplet is fallen into the collecting pit of lower end of the present invention.The upper end of the polywater mouth of a river 8 is connected with lower cover 3, lower end can make with
The consistent thin-slab structure in upper end can also make lower end the closing-in structure to contract, i.e. lower end forms the mouth of a river to contract,
Closing-in structure avoids the respective of large area on the polywater mouth of a river 8 from dripping, and water droplet lighter weight is easily disturbed by extraneous factors such as wind, shadow
Drip the route fallen for Xiangshui County, and the structure that lower end is shunk can ensure that water droplet merges into current whereabouts, prevent from blowing and splash phenomenon, really
It is smooth to protect recovery.
