Abstract
The utility model provides a liquid distributing device of a falling film evaporator, wherein a pipe distributor is arranged on the upper portion of a shell, the lower portion of the pipe distributor is fixedly connected with a disc distributer, and the lower portion of the shell is fixedly connected with a plate with a hole. The falling film evaporator of the device is characterized in that the material heating time is short, the efficiency is high, the falling film evaporator is not easily scaled, cleaning is easy, and the like. Thereby the liquid distributing device is widely applied in the industries such as chemical industry, light industry, medical industry and the like, and the effects of the liquid distributing device are to distribute material liquid into each heating pipe evenly and to form film to flow from the top to the bottom under the force of gravity and secondary steam.
Description
Technical field
The utility model relates to a kind of chemical industry evaporimeter, is specifically related to a kind of liquid distribution device of falling film evaporator.
Background technology
Traditional liquid distribution device generally adopts: the multilayer distributor makes liquid be uniformly distributed in tube sheet to be advanced in the heating tube by the tube sheet overflow again, because overflow skewness occurs through regular meeting; Feed liquid is poor at heating tube wall film-formation result, even the problem of dried wall occurs, and the inhomogeneities of cloth was just more obvious when especially load changed.
The utility model content
The utility model provides a kind of liquid distribution device of falling film evaporator.
For solving above technical problem, the liquid distribution device of a kind of falling film evaporator of the present utility model, it is characterized in that: described housing top is provided with pipe distributor, and fixedly connected disc type distributor below pipe distributor is at the fixedly connected plate with holes of lower part of frame.
Described pipe distributor is some branch pipe(tube)s formations that distribute on the trunk line.
Described disc type distributor is the serrate slot of band base plate, the aperture that gathers on the described base plate, and be provided with mozzle.
The lower end of described mozzle is tubaeform.
The perforated pipe plate that described lower part of frame is fixedly connected is provided with heat exchanger tube in the described hole.
Described mozzle is built in the heat exchanger tube, and concentric with heat exchanger tube.
The advantage of above structure is: the downward film evaporator of this device has material short, characteristics such as efficient is high, less scaling easy cleaning heat time heating time.Because of extensive use in the industries such as chemical industry, light industry, medicine, the effect of liquid distribution device is that feed liquid is distributed in the every heating tube equably, and along the heating tube inwall under the promotion of gravity and indirect steam, form and membranaceously flow from top to bottom.

Fig. 3 is the structural representation of the utility model disc type distributor.
Fig. 4 is the structural representation of the utility model tube sheet.
The specific embodiment
As shown in Figure 1, be provided with top on the top of housing 1 and be provided with pipe distributor 2, described pipe distributor 2 is made of some branch pipe(tube)s 4 that distribute on the trunk line 3, as shown in Figure 2; Effect is by trunk line 3 material to be introduced from the external world, evenly material is distributed by branch pipe(tube) 4.
Fixedly connected disc type distributor 3 below pipe distributor 2, as shown in Figure 3, described disc type distributor 3 is the serrate slot 5 of band base plate 4, aperture 6 gathers on the described base plate, and be provided with mozzle 7, effect is the material diversion that branch pipe(tube) 4 is distributed and, and can become membranaceous water conservancy diversion along the outer wall of mozzle 7 in order to make material, and flue is done in the bottom of mozzle 7.
At last, the fixedly connected perforated pipe plate 8 in the bottom of housing 1, as shown in Figure 4, and the equidistant hole 9 that has on the described tube sheet 8, inner-heating tube 10 in hole 9, and mozzle 7 extend out in the Tube Sheet of Heat Exchanger 10 in pipe distributor 2, forms concentric with heat exchanger tube 10.
During work, material evenly is distributed to material in the serrate slot 5 by branch pipe(tube) 4 from trunk line 3, then through serrate slot 5 by 6 uniform the flowing on the tube sheet 8 of the aperture on the base plate 4, be guided to heat exchanger tube 10 downwards through the wall of built-in mozzle 7 again material gasified.
