Further, the lower end of described surge chamber is disposed with one-level liquid distribution plate, two grades of liquid distribution plates.
Further, described one-level liquid distribution plate, the both sides of two grades of liquid distribution plates are provided with liquid barrier；
It is provided with aperture on described liquid barrier.
After this utility model uses above technical scheme, compared with prior art, have the advantage thatA kind of horizontal falling film evaporator liquid distributor, this liquid distributor can be by cold-producing medium distributed uniform, ensure that each evaporation tube can participate in heat transfer, prevent the generation of " evaporation tube dry blowing " phenomenon, extend the service life of evaporation tube, substantially increase the heat transfer coefficient of horizontal falling film evaporator, also improve the work efficiency of refrigeration unit simultaneously.
Through practice, this liquid distributor cloth liquid is uniform, and every evaporation tube can participate in heat transfer, the high (5000-30000w/ (m of heat transfer coefficient2DEG C)), more relatively reliable than flooded evaporator performance, there is wide popularizing application prospect.
With embodiment, this utility model is described in detail below in conjunction with the accompanying drawings.
Accompanying drawing explanation
Accompanying drawing 1 is the structural representation of a kind of horizontal falling film evaporator liquid distributor in this utility model embodiment；
Accompanying drawing 2 is the partial structurtes enlarged diagram of A in accompanying drawing 1；
In figure,
1-feed tube, 2-surge chamber, 3-liquid collecting room, 4-cover plate, 5-leak, 6-gusset, 7-one-level liquid distribution plate, bis-grades of liquid distribution plates of 8-, 9-liquid barrier.
Detailed description of the invention
In order to be more clearly understood from technical characteristic of the present utility model, purpose and effect, now comparison accompanying drawing illustrates detailed description of the invention of the present utility model.
Embodiment, as shown in Figure 1 and Figure 2, the liquid distributor of a kind of horizontal falling film evaporator, including feed tube 1, the lower end of feed tube 1 connects has surge chamber 2, feed tube 1 to be connected with surge chamber 2.
Surge chamber 2 be provided above with liquid collecting room 3, the top panel of surge chamber 2 is the lower panel of liquid collecting room 3, and the lower panel of liquid collecting room 3 is evenly arranged with aperture.The top panel of liquid collecting room 3 is cover plate 4.Being provided with leak 5 on the side panel of liquid collecting room 3, leak 5 is horizontally arranged along liquid collecting room 3 side panel.
Liquid collecting room 3 is internally provided with gusset 6, and gusset 6 is arranged along the vertical direction of liquid distributor, and the length of gusset 6 is less than the height of liquid collecting room 3, and gusset 6 is fixing with cover plate 4 to be connected.
