The invention discloses a kind of plug-in type falling film evaporator liquid distribution trough, mainly including five gear shaping, reverse frustoconic inclined-plane cavity, flow-guiding mouth, conical floor, through hole parts.The gear shaping, reverse frustoconic inclined-plane cavity and conical floor are integrally formed, the gear shaping is evenly arranged in the falling liquid film mouth of pipe, reverse frustoconic inclined-plane cavity and conical floor are located at immediately below gear shaping, the flow-guiding mouth is evenly distributed on reverse frustoconic inclined-plane cavity and extends to bottom, and through hole is provided with the top of the conical floor.This plug-in type falling film evaporator liquid distribution trough is compact-sized rationally, easy to loading and unloading, and positioning precision is high, and liquid film is evenly distributed in film supplying tube, and evaporation effect is good.
Description
Technical field
The present invention relates to evaporation equipment technical field, more particularly to a kind of plug-in type falling film evaporator liquid distribution trough.
Background technology
Falling film evaporator is the typical case in evaporation equipment, and falling film evaporator advantage is heat transfer coefficient height, material heat time
It is short, processed suitable for heat sensitive material, be a kind of energy-efficient equipment, be widely used in chemical industry, light industry and food processing
Industry.The service behaviour of falling film evaporator is critically depend on liquid distribution trough and the liquid film in film supplying tube is distributed, therefore distributor is set
Whether meter rationally directly affects the heat-transfer effect, heat exchange efficiency and operational stability of falling film evaporator.
At present, common liquid distribution trough is broadly divided into：Overflow type, slotted disk type, comb type, spraying type etc., its is main
The problem of existing is due to that liquid distribution caused by sprinkling, sprinkle mode is uneven, have impact on the cloth film effect in film supplying tube, from
And reduce heat-transfer effect.
The content of the invention
It is an object of the invention to provide a kind of plug-in type falling film evaporator liquid distribution trough, the distributor can be to liquid
Uniform cloth film is carried out, makes to avoid the occurrence of dry wall, channel and Biased flow phenomenon in film supplying tube, so as to make falling film evaporator stable.
The technical problems to be solved by the invention are realized using following technical scheme：
A kind of plug-in type falling film evaporator liquid distribution trough, it is characterised in that mainly including gear shaping (1-1), reverse frustoconic
Five inclined-plane cavity (1-2), flow-guiding mouth (1-3), conical floor (1-4), through hole (1-5) parts.The gear shaping (1-1), rounding
Platform shape inclined-plane cavity (1-2) is integrally formed with conical floor (1-4), and the gear shaping (1-1) is evenly arranged in the falling liquid film mouth of pipe, described
Reverse frustoconic inclined-plane cavity (1-2) and conical floor (1-4) are located at immediately below gear shaping (1-1), and the flow-guiding mouth (1-3) is uniformly divided
Cloth is in reverse frustoconic inclined-plane cavity (1-2) and extends to bottom, and through hole (1-5) is provided with the top of the conical floor (1-4).
Further, there is a step gear shaping (1-1) edge, and screwed hole is provided with thereon.
Further, reverse frustoconic inclined-plane cavity (1-2), its outside inclined-plane is horizontal by 45 ° -60 °.
Further, it is back taper that the flow-guiding mouth (1-3) is open from inside to outside.
Further, flow-guiding mouth (1-3) length and width is according to the specific flow and actual process demand of liquid
Design.
The invention has the advantages that compact-sized, rationally easy to loading and unloading, positioning precision is high, liquid film distribution in film supplying tube
Uniformly, gas-liquid pressure balance in film supplying tube, is not in dry wall, channel or Biased flow phenomenon, and evaporation effect is good.

Embodiment
Presently in connection with accompanying drawing and case study on implementation, the present invention is further detailed explanation.These accompanying drawings are simplified show
It is intended to, only illustrates the basic structure of the present invention in a schematic way, therefore it only shows the composition relevant with the present invention.
In Fig. 1, plug-in type falling film evaporator liquid distribution trough is consolidated by the screwed hole in gear shaping (1-1) edge step
It is fixed, improve the positioning precision of plug-in type falling film evaporator liquid distribution trough.Liquid is from the gap between gear shaping (1-1) and rounding
Platform shape cavity (1-2) flows into, and due to reverse frustoconic cavity (1-2) presence, slow down the flow velocity of liquid, avoids liquid from flying everywhere
Splash, ensure that trickle is uniformly distributed along pipe.Flow-guiding mouth (1-3) is evenly distributed on reverse frustoconic inclined-plane cavity (1-2)
And bottom is extended to, liquid is flowed out by flow-guiding mouth (1-3), avoids the occurrence of bias current or dry wall caused by liquid film skewness
Phenomenon, while avoid the occurrence of hydrops phenomenon.It is back taper that the flow-guiding mouth (1-3) is open from inside to outside, makes trickle more
Uniformly.Conical floor (1-4) top center is provided with through hole (1-5), facilitates gas to escape, and maintains gas-liquid pressure difference in film supplying tube to put down
Weighing apparatus, avoids the occurrence of Concerning Flooding Phenomenon.
It is complete by above-mentioned description, relevant staff using the above-mentioned desirable embodiment according to the present invention as enlightenment
Various changes and amendments can be carried out without departing from the scope of the technological thought of the present invention' entirely.The technology of this invention
Property scope is not limited to the content on specification, it is necessary to determines its technical scope according to right.
