Description
Technical field
The present invention relates to a kind of evaporimeter liquid distribution trough, relate in particular to a kind of liquid distribution trough can be applicable in falling film evaporator, belong to heat exchange evaporation equipment technical field.
Background technology
Falling film evaporator is a kind of evaporimeter efficiently, and because it has, heat transfer coefficient is high, the heating material time is short, heat transfer temperature loss is little, be easy to process heat sensitive material and save the advantages such as the energy is widely used in the field of industrial productions such as chemical industry, medicine, food, metallurgy, light industry and desalinization, sewage disposal.The operation principle of falling film evaporator is that pending material is pumped into evaporator heating chamber top, after liquid distribution trough uniform distribution, by the gravity of self, material is along the membranaceous Uniform Flow from top to bottom of the vertical one-tenth of evaporation tube inner surface, steam outside pipe passes to material by the form of convection current and conduction heat, material flows with very fast speed from top to bottom in pipe at the indirect steam that produced by thermal process together with material, flow out liquid-vapor mixture spontaneous evaporation pipe lower end, enter subsequently separation chamber and carry out vapor-liquid separation, complete evaporation process.For liquid can be distributed in every evaporation tube uniformly, and make liquid in the time that evaporation tube inwall flows, can form uniform liquid film from top to bottom under the effect of gravity and indirect steam, liquid distribution trough just must be set.
In falling film evaporation process, only form the liquid film of even decline on the surface of evaporator evaporation inside pipe wall, could effectively conduct heat, liquid film is more thin more even, and heat-transfer effect is better.If feed liquid skewness, there is bias current or channel in the liquid film that enters each evaporation tube, liquid film can not cover wetting the inwall of whole evaporation tube, cause the liquid film in pipe to interrupt or evaporate to dryness, on the one hand can make effective heat transfer area reduce, on the other hand the wall temperature that makes evaporation tube be raise rapidly, form and scab or fouling thereby cause in feed liquid scale-forming ion to separate out or stick on tube wall, further reduce heat transfer coefficient, evaporation efficiency is declined.Therefore,, for ensureing feed liquid even cloth film and prevent fouling in every evaporation tube, must there is functional, not susceptible to plugging liquid distribution trough.
Notification number is CN202666436U, name is called in the Chinese utility model patent of " falling film evaporator of liquid distribution trough and carrying liqs distributor " and discloses a kind of liquid distribution trough, this liquid distribution trough comprises the baffle being supported on falling film evaporator tube sheet, between baffle and tube sheet, be provided with the support component for supporting baffle, thereby make to there is gap between baffle and tube sheet, this gap forms the feed pathway that enters for liquid evaporation tube, the center of baffle is inserted into the newel in evaporation tube while being also provided with use, the lower end of newel is provided with the distribution grid of the truncated cone-shaped structure that is up-small and down-big, the equal diameters of the diameter of this distribution grid end face and newel bottom surface.The feed pathway of this liquid distribution trough is arranged on evaporation tube both sides, and the surrounding concave surface along baffle when liquid enters flows to evaporation tube inner surface with radiation wire, can avoid like this suspended solid to deposit at heat exchanger tube sheet place.But this liquid distribution trough can only make liquid along continuous straight runs flow in evaporation tube, just liquid must be sprayed on tube sheet in use, liquid could flow in evaporation tube the gap between baffle and tube sheet.
