Abstract
The utility model discloses a flow equalization type liquid distributer applied to falling film type heat exchange equipment. The flow equalization type liquid distributer comprises a liquid distribution pipe (4), wherein an overflow groove (14) is formed on a liquid inlet pipe orifice of the liquid distribution pipe (4); the liquid distribution pipe (4) is arranged on a liquid distribution groove (3); a flow guiding ring (6) is arranged on the liquid distribution groove (3) through a connecting plate (5); and a flow guiding plate (7) is arranged on the flow guiding ring (6). By adopting the flow equalization type liquid distributer, liquid can be distributed uniformly through the liquid distribution groove and the liquid distribution pipe to flow a pipe plate of the falling film type heat exchange equipment and liquid is distributed uniformly in each heat exchange pipe, so that the problems that liquid is distributed unevenly, is easy to block, is sprayed on the housing wall and the like in the liquid distributers with other modes are solved, the formation of an inner wall film of the heat exchange pipe is contributed, the heat exchange efficiency is improved, and the requirements of high-end customers are met completely.
Description
Technical field
The present invention relates to a kind of heat-exchange apparatus, relate to a kind of liquid distribution trough that is applied on the film-lowering type heat transmission equipment specifically.
Background technology
At present, liquid distribution trough mainly is to be applied on the film-lowering type heat transmission equipment and liquid is distributed, sprays, and its uniformity coefficient to liquid distribution directly has influence on the formation and the heat exchange efficiency of heat exchanger tube inwall film.Liquid distribution trough commonly used has various ways, as impact type shower, shower nozzle type sprinkler, straight pipe with holes formula, porous disc tubular type, comb porous type sprinkler, overflow slot type shower etc., its problem that mainly exists is: because spray, the sprinkle mode makes liquid distribution inhomogeneous and stop up or require processing and installation accuracy thereof more high easily, can't satisfy the requirement of high-end customer.
Summary of the invention
The objective of the invention is to overcome above-mentioned deficiency, can carry out equally distributed uniform flow type liquid distribution trough to the liquid in the film-lowering type heat transmission equipment and provide a kind of.
Objects of the present invention are achieved through the following technical solutions: a kind of uniform flow type liquid distribution trough, comprise liquid distributor, and on the feed liquor mouth of pipe of described liquid distributor, be provided with overflow launder, described liquid distributor is contained on the cloth liquid bath.On described cloth liquid bath, baffle liner is housed, on this baffle liner deflector is housed by connecting plate.
After adopting structure of the present invention, liquid flows on the tube sheet of film-lowering type heat transmission equipment and makes each heat exchanger tube institute cloth liquid even through the even distribution of cloth liquid bath, liquid distributor, avoided other form liquid distributor problem, the problem includes: liquid distribution is uneven and easily stop up and be sprayed onto problem such as shell wall.Thereby help the formation of heat exchanger tube inwall film and improved heat exchange efficiency, satisfy the high-end customer requirement fully.

The specific embodiment
Below the present invention is described in further detail by accompanying drawing and embodiment.
Referring to figs. 1 through Fig. 4 as can be known, the present invention is applied to the uniform flow type liquid distribution trough on the film-lowering type heat transmission equipment, comprises liquid distributor 4, is provided with overflow launder 14 on the feed liquor mouth of pipe of described liquid distributor 4, and described liquid distributor 4 is contained on the cloth liquid bath 3.On described cloth liquid bath 3, baffle liner 6 is housed, on this baffle liner 6 deflector 7 is housed by connecting plate 5.Overflow launder 14 profiles on the feed liquor mouth of pipe of described liquid distributor 4 are U type or V-type.
Wherein, baffle liner 6 is above cloth liquid bath 3, and the feed tube 8 on deflector 7 and this film-lowering type heat transmission equipment is connected; Liquid distributor 4 is fixed by welding on the cloth liquid bath 3, and baffle liner 6 is fixed on the cloth liquid bath 3 by connecting plate 5, and deflector 7 is fixed by welding on the baffle liner 6, has (certain) gap between deflector 7 and the baffle liner 6.
Pipe railway carriage or compartment 9 on this film-lowering type heat transmission equipment is connected with heat transmission equipment main body 1 by flange 11, sealing ring 10, bolt and nut 12, feed tube 8 is fixed by welding on the pipe railway carriage or compartment 9, tube sheet 2 and several heat exchanger tubes 15 also are housed in the heat transmission equipment main body 1, the cloth liquid bath 3 of described liquid distribution trough is fixed on tube sheet 2 tops by supporting screw 13, liquid distributor 4 is sleeved on heat exchanger tube 15 tops accordingly, and (liquid distributor 4 is bigger than the external diameter of heat exchanger tube 15, quantity is less, have a determining deviation between the two), as Fig. 1, Fig. 2, shown in Figure 4.
As shown in the figure, uniform flow type liquid distribution trough of the present invention is contained in the heat transmission equipment body interior of film-lowering type heat transmission equipment, its operation principle is: liquid flows into cloth liquid bath 3 by the water conservancy diversion (promptly passing through gap between deflector and the baffle liner) of deflector 7, baffle liner 6 earlier through feed tube 8, evenly flows on the tube sheet 2 along the liquid distributor inwall through the even distribution of cloth liquid bath and by the U type overflow launder 14 on the liquid distributor 4; Then, liquid flows down and forms heat exchanger tube inwall film stream through tube sheet along the heat exchanger tube inwall again.
Claims (3)
1. a uniform flow type liquid distribution trough comprises liquid distributor (4), it is characterized in that: be provided with overflow launder (14) on the feed liquor mouth of pipe of described liquid distributor (4), described liquid distributor (4) is contained on the cloth liquid bath (3).
2. uniform flow type liquid distribution trough as claimed in claim 1 is characterized in that: go up at described cloth liquid bath (3) and by connecting plate (5) baffle liner (6) is housed, deflector (7) is housed on this baffle liner (6).
