The invention provides a novel horizontal falling film liquid distributing device. The novel horizontal falling film liquid distributing device comprises a liquid inlet pipe and a liquid distributing pipe, wherein the liquid inlet pipe is provided with a liquid inlet, and communicated with the liquid distributing pipe; the liquid distributing pipe is provided with flow guiding sheets, overflow grooves, overflow holes, liquid distributing grooves and liquid distributing holes. Fluid flows into the liquid distributing pipe from the liquid inlet of the liquid inlet pipe, and is firstly uniformly distributed into the overflow grooves in the two sides through the flow guiding sheets, after the liquid in the overflow grooves is full, the fluid flows into the liquid distributing grooves in the two sides to be gathered, finally, the fluid flows out of the liquid distributing holes, and is sprayed on the outer wall faces of upper heat exchanging pipes at the lower position, and then a stable and uniform liquid film is formed. By means of the horizontal falling film evaporation and liquid distributing device, the phenomenon that liquid distribution of a horizontal falling film in the pipe length direction is uneven can be avoided, the probability that the liquid distributing holes are clogged is lowered, and the effect that the fluid is uniformly distributed in the pipe length direction is achieved.
Description
technical field [0001] The invention relates to the technical field of falling film evaporation heat exchange, in particular to a horizontal falling film liquid distributor for uniform liquid distribution. Background technique [0002] Compared with conventional heat exchange equipment, horizontal falling film heat exchange equipment has the characteristics of rapid gas-liquid separation, small heat transfer temperature difference, less liquid filling, compact structure, large heat exchange area, and high heat exchange efficiency. It is widely used in seawater Desalination, petrochemical, refrigeration and air conditioning, food and pharmaceuticals and other fields. [0003] One of the conditions for the normal operation of the horizontal tube falling film heat exchanger is that the liquid is evenly distributed to each heat exchange tube in the form of a film, and a continuous and uniform stable liquid is maintained in the entire circumferential and axial directions of each ...
