Orifice plate or sketch plate, have on sketch plate or between sketch plate and mixed zone side wall and hold the through hole that mixed liquor passes through.Utilize pipe
The principle of road mixing causes the upper strata light phase to flow back and the heavy phase fed to be sufficiently mixed in mixed zone.
In order to extend turbulent closure scheme length in mixed zone, preferable technical scheme is that leakage area is arranged on the two of mixed zone
Side, mixed zone are communicated by the opening of one end with leakage area, and charging aperture is arranged on the other end of mixed zone.Further, mix
Area is located at the diametrical position of uniform device.
In order to ensure that the liquid in leakage area comes downwards in two level distributing slot in time, preferable technical scheme is that leakage area is
Two endless grooves coplanar with mixed zone.Endless groove is corresponding up and down with two level distributing slot two, can suitably increase liquid pass hole
Quantity, while the vacant area outside endless groove also ensures that the smooth of ascending air passes through.
Cause mixed liquor excessive in order to avoid inlet amount is excessive, preferable technical scheme is that the height of dividing plate is equal to or omited
Higher than the Sidewall Height of one-level major trough.
The advantages of the present invention are：
The evaporator is with liquid pool uniform device by the way that one-level major trough is isolated into mixed zone and leakage area, the liquid of lower floor's backflow
Enter leakage area after mixing in mixed zone with feeding, avoid the light phase that upper strata is flowed back and the heavy phase of charging from being distributed in uniform device
The problem of inequality, incomplete mixing, ensure the mass transfer separative efficiency of evaporation equipment；
Structure improvement is carried out to major trough of the prior art and catch tray, simple in construction, fusion length and materials are small, manufacture
It is convenient.
