Equipped with equally distributed liquid separation hole, the equal liquid bottom plate is equipped with the equal liquid hole being interspersed, the liquid separation baffle and equal liquid bottom
For plate in vertical direction there are spacing, the center line of the equal liquid hole is mutually be overlapped with the center line of the heat exchanger tube in horizontal pipe falling film evaporator
It closes.
The inlet opening is arranged in the geometric center position of liquid separation baffle and equal liquid bottom plate.
The equal liquid separation hole of uniformly distributed diameter is offered on the liquid separation baffle, nearside is leaned in liquid separation hole on the outermost side
Plate.
For the line of centres of every three adjacent equal liquid holes at equilateral triangle, the triangular apex is located just at changing for arrangement
Above the center line of heat pipe.
The diameter of equal liquid hole is less than the diameter in liquid separation hole, and equal liquid hole, liquid separation hole are round rectangular or oval.
The liquid distributor suitable for horizontal pipe falling film evaporator of the utility model is on the whole double-deck, the closed hollow knot
Structure, cloth liquid chamber are divided into the equal liquid chamber in top liquid separation room and bottom by horizontal liquid separation partition board.Refrigerant liquid is entered by inlet opening
Liquid separation room first time cloth liquid is completed by the liquid separation hole liquid separation on liquid separation baffle.To ensure that liquid separation is uniform, reduce directly to feed liquor
The diameter in the center liquid separation hole in hole.The refrigerant liquid for flowing into equal liquid chamber is equably dropped in the heat exchange of its underpart by equal liquid hole
Pipe surface completes second of cloth liquid.It is uniform with liquid separation, simple in structure, the advantages of good effect of heat exchange.
