Abstract
The utility model relates to a liquid distributing device of a falling-film evaporator, which is developed specially for a large-sized falling-film evaporator with a vertical tube, and mainly comprises a spraying device which is formed by an inlet pipe and a main pipe as well as branch pipes at two sides thereof, an upper layer distribution disc and a lower layer distribution disc and a plug distributor. Materials enter the main pipe through the inlet pipe, are sprayed by branch pipes, are distributed at the periphery of each heat exchange pipe on a tube plate by the upper layer distribution disc and the lower layer distribution disc, and then enter each heat exchange pipe in a whirly manner by the plug distributor to form a continuous and uniform thin film at the inner wall of the heat exchange pipe. The device can lead liquid to be reasonably distributed and the liquid film to be uniformly distributed, is especially applicable to the large-sized falling-film evaporator, is simple for manufacturing and is an ideal liquid distributing device of the falling-film evaporator.
Description
Technical field:
The utility model relates to a kind of liquid distribution device of falling film evaporator, belongs to the evaporation equipment technical field.
Background technology:
The vertical tube falling film evaporator is a kind of energy-efficient evaporation equipment, is widely used in the industries such as chemical industry, light industry, food, pharmacy, metallurgy and desalinization.The primary structure of falling film evaporator is a vertically arranged E type monoshell single pipe heat exchanger, and the shell side side is for adding hot fluid, and the tube side side is the material that is evaporated.The material that evaporates enters from tube side top, make material be the film shape by liquid distribution device and flow downward along the tube wall of every heat exchanger tube, in this process liquid be evaporated carry dense.Make feed liquid can be equably in pipe film forming, rational liquid distribution device must be set, distribution apparatus structure quality all has a direct impact for film-formation result, condensate film stability, the control of falling liquid density, thereby directly has influence on the heat exchange efficiency of evaporimeter.Device maximizes has at present become one of energy-saving and cost-reducing approach, and along with the progressively maximization falling film evaporator of chemical plant installations is increasing, the effect of liquid distribution device is also more outstanding.
Summary of the invention
In order to adapt to the requirement that falling film evaporator maximizes, the utility model provides a kind of liquid distribution device of falling film evaporator, and it can guarantee that material is evenly distributed on each root tubulation inwall of heater and with even membranaceous decline.
The technical solution adopted in the utility model is:
The liquid distribution device of falling film evaporator, comprise inlet tube, house steward, arm, last distributing disc, pull bar, distance sink tube, following distributing disc and plug distributor, connect a house steward in the inlet tube lower end, house steward's both sides are provided with arm, radially are provided with liquid flow hole in the scope of bottom at every arm.Below house steward and arm, be provided with the upper and lower distributing disc in cloth dishful hole, upper and lower distributing disc is fixed on the upper perforated plate by pull bar and distance sink tube.Be provided with the plug distributor on the top that is positioned at the heat exchanger tube on the upper perforated plate, have skewed slot in the upper surface of plug distributor, the inner tube surface of plug distributor bottom is a Taper Pipe pipe face.
Operation principle of the present utility model is as follows: after adopting the liquid distribution device of above-mentioned falling film evaporator, material enters house steward by inlet tube, evenly be sprayed on the distributing disc through arm, material is through behind the upper and lower two-layer distributing disc, be evenly distributed on every heat exchanger tube on the tube sheet around, make the material eddy flow enter every heat exchanger tube by the plug distributor, and form continuously film uniformly at the heat exchanger tube inwall.
The beneficial effects of the utility model are:
This device can make liquid rationally distribute, and liquid film is evenly distributed, and is specially adapted to large-scale vertical tube falling film evaporator, and device fabrication is simple, is the desirable liquid distributor of falling film evaporator.

The specific embodiment
Below in conjunction with drawings and Examples utility model is further specified:
Shown in Fig. 1-6, the liquid distribution device of falling film evaporator is made up of inlet tube 1, house steward 2, arm 3, last distributing disc 4, pull bar 5, distance sink tube 6, following distributing disc 7 and plug distributor 8:
Connect a house steward 2 the same with inlet tube 1 diameter in inlet tube 1 lower end, house steward 2 length is decided on the bobbin carriage internal diameter, according to required actual internal area plurality of rows (being 7 rows in the present embodiment) arm 3 is set in house steward 2 both sides, radially open 5 row liquid flow holes in the scope of 120 ° of bottoms at every arm 3, arm 3 actual internal areas need greater than house steward's 2 actual internal areas, and the liquid flow hole actual internal area should be greater than arm 3 actual internal area (see figure 1)s.
Below house steward 2 and arm 3, the last distributing disc 4 in cloth dishful hole 10 and the following distributing disc 7 in cloth dishful hole 11 are set, upper and lower distributing disc 4 and 7 is fixed on the upper perforated plate by pull bar 5 and distance sink tube 6.The quantity in the dish hole 10 of last distributing disc 4 is consistent with the quantity of heat exchanger tube 9, its center, hole projection on tube sheet overlaps with the center of heat exchanger tube 9, and down the dish hole 11 of distributing disc 7 in the projection on the tube sheet around the heat exchange pore, around the every heat exchange pore projection in 6 holes is arranged and be regular hexagon and distribute, this arrangement mode can be realized the multiple spot cloth (see figure 4) to pipe, and the dish hole 10 of upper and lower distributing disc and 11 size go out the stream mode by liquid level and dish hole on flow, dish hole number, the distributing disc and determine.
On the top that is positioned at the heat exchanger tube 9 on the upper perforated plate, plug distributor 8 is set, offer 4 45 ° rectangle skewed slot in the upper surface of plug distributor 8, again plug distributor 8 bottom inner tube surfaces are processed into Taper Pipe pipe face, to prevent because of stopping with the excessive liquid film that causes of heat exchanger tube 9 difference in internal diameters less than 15 °.
