3, to adopt the angle of converging transition be 12-15 while spending to the utility model, acid bath liquid carried out pressurized effect good; The angle of divergent segment is 15-17 while spending, and acid bath liquid is carried out decompressing speed-increasing effective.
4, the utility model adopts and also comprises the protection tube that is arranged on the jet pipe outside, and an end of protection tube is stiff end, and the other end is fixed on the jet pipe cap; By gripper shoe, umbrella hat and protection tube are linked together, be fixed on multi-effect evaporator, jet pipe is connected with bolt with protection tube, is convenient to like this jet pipe and changes.
5, the utility model employing jet pipe cap is umbrella hat, and umbrella hat can prevent the backflow of drop, and drop is evenly in umbrella hat falls into multi-effect evaporator; The acid bath liquid that square umbrella pipe cap more is conducive to atomization is scattered to four direction.
6, the utility model adopts the jet pipe cap to be provided with gripper shoe, and gripper shoe fixedly secures the jet pipe cap on protection tube; Due to the sudden change of the pressure-speed of nozzle hole, cause the nozzle hole vibrations, gripper shoe can further adopt triangular structure to increase the rigidity of jet pipe cap.
7, the acid bath liquid of jet pipe ejection of the present utility model has increased the specific area of acid bath liquid in the flash distillation plant space, be beneficial to the water evaporation of acid bath liquid, increase simultaneously the vacuum of the nozzle mouth of pipe due to the pressure-speed sudden change of jet hole, also be conducive to the water evaporation of acid bath liquid.
