Abstract
The utility model relates to a liquid distribution device, in particular to a liquid distribution device in a falling film evaporator. The liquid distribution device is provided with a header, wherein a feeding pipe is arranged at the top of the header; a scattering disk is arranged below the feeding pipe in the header; a corrugated overflow groove is formed in the top of the scattering disk; sieve holes are formed in the bottom; a distribution plate is arranged at the lower part of the scattering disk; a plurality of holes are uniformly distributed in the distribution plate; a tube plate is arranged at the lower part of the distribution plate; a plurality of holes are uniformly formed in the tube plate; each hole corresponds to each heating tube at the lower part of the tube plate; and an umbrella-shaped film distributor is arranged at the top of each heating tube. The liquid distribution device in the falling film evaporator, which is disclosed by the utility model, has the advantages that the film forming is stable and a heat transfer coefficient is high, so that an optimal annular space can be selected and the certain functions of increasing the heat transfer efficiency and saving energy sources are achieved.
Description
Technical field
The utility model relates to a kind of liquid distribution device, is specifically related to the liquid distribution device in a kind of falling film evaporator.
Background technology
In the prior art, the liquid distribution trough pattern of falling film evaporator is a lot, and what really can extensively use in falling film evaporator is the disc type distributor, but the disc type distributor, and no matter single disc-type, double plate or three disc types still can occur: 1, material skewness; 2, produce the phenomenon such as bias current.
The umbellate form filming device is used for many years, but old-fashioned umbellate form filming device still can occur: 1, processing and manufacturing requires high; 2, film-formation result is undesirable; 3, film partially is so that the part heating tube phenomenon such as film forming not.
The utility model content
In order to solve the technical problem that exists in the prior art, it is a kind of simple in structure that the purpose of this utility model is to provide, and purchases, maintenance and operating cost is cheap, makes simultaneously the liquid distribution device that requires in the lower falling film evaporator.
The technical solution adopted in the utility model is as follows:
Liquid distribution device in the falling film evaporator is characterized in that, has bobbin carriage, and the bobbin carriage top is provided with feed pipe, and the below of feed pipe is provided with dispersion impeller in the bobbin carriage, and the dispersion impeller top has the corrugated overflow launder, and the bottom is provided with sieve aperture; The bottom of dispersion impeller is provided with distribution plate, is evenly equipped with several holes on the distribution plate; The bottom of distribution plate is provided with tube sheet, is evenly equipped with several holes on the tube sheet, and each hole is corresponding with each heating tube of tube sheet bottom; The heating tube top is provided with the filming device that is umbrella.
Further, evenly stagger in the projection on the tube sheet and the hole on the tube sheet in the hole of distribution plate.
Further, described umbrella filming device is fixed on the inwall at heating tube top by several feets.
Further, described umbellate form filming device and heating tube inwall annular space are 1.5-2.0mm.
Liquid distribution device in the utility model falling film evaporator, compared with prior art, its beneficial effect shows:
1, processing and manufacturing requires lowly, only need to or simmer 3 identical feets of system and collude and get final product in the umbrella cover weldering, need not the requirement of feet proposition corresponding size.
2, to umbrella cover without unified plane requirement, all have material to get final product film forming in each heating tube.
3, umbellate form filming device and heating tube inwall annular space just can be set before manufacturing.And can provide optimum film forming thickness according to mature experience, general control is about 1.5-2.0mm.
4, because film forming is stable, heat transfer coefficient is high, can select optimum annular space, and to improving heat transfer efficiency, energy savings has certain effect.
Description of drawings
For the ease of it will be appreciated by those skilled in the art that below in conjunction with accompanying drawing utility model is further described.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is distribution plate hole and heating pore relative position figure on tube sheet.
The specific embodiment
See also Fig. 1 and 2, the liquid distribution device in the falling film evaporator has bobbin carriage 2, and bobbin carriage 2 tops are provided with feed pipe 1, and the below of bobbin carriage 2 interior feed pipes 1 is provided with dispersion impeller 3, and dispersion impeller 3 tops have the corrugated overflow launder, and the bottom is provided with sieve aperture.
The bottom of dispersion impeller 3 is provided with distribution plate 4, is evenly equipped with several holes 8 on the distribution plate 4.
The bottom of distribution plate 4 is provided with tube sheet 5, is evenly equipped with several holes 9 on the tube sheet 5, and each hole 9 is corresponding with each heating tube 7 of tube sheet 5 bottoms.
Heating tube 7 tops are provided with the filming device 6 that is umbrella, and umbrella filming device 6 is fixed on the inwall at heating tube 7 tops by several feets, and umbellate form filming device 6 is 1.5-2.0mm with heating tube 7 inwall annular spaces.
Evenly staggering in the hole 9 of the hole 8 of distribution plate 4 on the projection on the tube sheet 5 and tube sheet 5, guarantees that material enters in the heating tube 7 by the overflow mode at last.The aperture in the hole 8 of distribution plate 4 is preferably 6mm, and guarantees whole circulation area and to enter heating tube 7 interior material flow demand areas consistent.The aperture is too small easily to result in blockage, and the aperture is excessive and hole count is too many, easily causes the partial bores cutout.
During operation, material enters dispersion impeller 3 by feed pipe 1, flows out through dispersion impeller 3 weir overflows and from the sieve aperture of trying to get to the heart of a matter, and then reassigns to tube sheet 5 through distribution plate 4.And material is flowing into the umbellate form filming device that is inserted on the heating tube 7 in the overflow mode on the tube sheet 5, and the annular space self film that finally enters between heating tube 7 and the umbellate form filming device 6 flows down along heating tube 7 inwalls.
Above content only is to the utility model structure example and explanation; under those skilled in the art described specific embodiment is made various modifications or replenish or adopt similar mode to substitute; only otherwise depart from the structure of utility model or surmount this scope as defined in the claims, all should belong to protection domain of the present utility model.
