Abstract

The invention discloses a liquid distributor for an evaporator. The liquid distributor comprises a central post and a distribution plate, wherein the central post is downwards inserted into an evaporation pipe of the evaporator when being used, the distribution plate is connected to the bottom end of the central post, the diameter of the top surface of the distribution plate is equal to that of the bottom surface of the central post, a cylinder which is arranged inside the evaporation pipe in a sheathing manner is arranged at the periphery of the central post, the axis of the cylinder is overlapped with the axis of the central post, a connecting rib plate for connecting the cylinder with the central post together is arranged between the cylinder and the central post, a gap is formed between the central post and the cylinder, the upper end of the cylinder is connected with a support lug, and the thickness of the wall surface of the cylinder is reduced gradually reduced from top to bottom. When the liquid distributor is used, liquid can vertically enter the cylinder through the gap between the central post and the cylinder, and is uniformly distributed on the inner wall of the cylinder or the evaporation pipe through the distribution plate, and as the thickness of the wall surface of the cylinder is reduced gradually, a layer of uniform flowing liquid membrane is formed on the inner wall of the evaporation pipe when liquid flows downwards, and the heat exchange efficiency of the evaporator can be effectively improved.

Description

technical field [0001] The invention relates to a liquid distributor for an evaporator, in particular to a liquid distributor applicable to a falling film evaporator, and belongs to the technical field of heat exchange and evaporation equipment. Background technique [0002] Falling film evaporator is a kind of high-efficiency evaporator, which is widely used in chemical industry, medicine, food, etc. , metallurgy, light industry and seawater desalination, sewage treatment and other industrial production fields. The working principle of the falling film evaporator is that the material to be treated is pumped into the top of the heating chamber of the evaporator, and after being evenly distributed by the liquid distributor, with the help of its own gravity, the material flows vertically along the inner surface of the evaporator tube into a film shape and flows uniformly from top to bottom. , the steam outside the tube transfers heat to the material through convection and con...
