Abstract
The utility model discloses a shower nozzle type spray distributor for a falling film evaporator. The shower nozzle type spray distributor for the falling film evaporator comprises a tank body, a mounting base, a pipe plate and a shower nozzle type sprayer, wherein the pipe plate is arranged in the tank body and isolates a cavity into an upper cavity and a lower cavity; a mounting port is formed in the top of the tank body; the shower nozzle type sprayer is mounted at the mounting port through the mounting base. According to the shower nozzle type spray distributor for the falling film evaporator, liquid materials can be distributed on the inner surfaces of vertical falling film array pipes reasonably and uniformly after spraying, atomization, diffusion and distribution; liquid films are distributed on the inner surfaces of all the vertical falling film array pipes reasonably and uniformly, so complete utilization of heat transfer area can be guaranteed, the phenomenon of dry wall and scaling on the surfaces of the array pipes is avoided, the falling film evaporator can operate efficiently and stably, the operation period of the falling film evaporator is prolonged, the cleaning frequency is reduced, and the high-efficiency stable using characteristic of the falling film evaporator can be completely exerted.
Description
Technical field
The utility model relates to a kind of distributor, relates in particular to a kind of spray distribntor of the shower-head type for falling film evaporator.
Background technology
Evaporimeter is that the solution that the mode by heat exchange will contain the fixedness solute is heated to the boiling situation, makes partial solvent vaporize and be removed, thereby improves the concentration of solute in solvent.
Falling film evaporator in evaporimeter is for the liquid material heating evaporation is concentrated into to required liquid material concentration, and falling film evaporator will have the key of the operational effect of efficient stable to be that whether the distribution of liquid film is rationally even.Existing a lot of falling film evaporator distributes not rationally due to liquid film and is not too even, cause falling film evaporator can't move efficiently when actual motion, heat transfer area can not take full advantage of, also have after the Local Dry wall and produce the phenomenon of tubulation fouling and the equipment cycle of operation is shortened increase cleaning frequency, the efficiency of evaporimeter operation is reduced greatly.
The utility model content
The purpose of this utility model is to solve the problems of the prior art, provides a kind of liquid film to distribute rationally and the uniform shower-head type spray distribntor for falling film evaporator.
The technical solution of the utility model is: the shower-head type spray distribntor for falling film evaporator comprises tank body, mount pad and tube sheet; Also comprise a shower-head type spray; Described tube sheet is located in tank body and described cavity is isolated into to upper and lower two chambers; Top at described tank body is provided with installing port, and described shower-head type spray is installed on this installing port place by mount pad.
Described shower-head type spray head is provided with the shower nozzle orifice plate, and described shower nozzle orifice plate sprays over against upper chamber.
Described shower-head type spray is positioned at the middle at tank body top.
Described mount pad is welded in the top of described tank body.
The inwall of described tube sheet and tank body circumferentially joins.
Be provided with a plurality of overflow pipes on described tube sheet.
The utility model adopts the shower-head type spray distribntor on the top of the vertically moving membrane tubulation of falling film evaporator, its top has been provided with spray atomizing and has disperseed the shower nozzle orifice plate distributed, the outlet of the shower nozzle orifice plate of described shower-head type spray distribntor has been the liquid point that spray atomizing disperses, complete liquid point that spray atomizing disperses guarantee liquid material side's aglucon this uniformly under condition also through below tube sheet a part of liquid material completed to primary overflow distribute.The utility model can guarantee that liquid material rationally is evenly distributed in the inner surface of vertically moving membrane tubulation after spray atomizing disperses to distribute, because having, the inner surface of all vertically moving membrane tubulations distributes rationally liquid film uniformly, thereby can guarantee taking full advantage of of heat transfer area, guarantee that the tubulation surface can not produce the phenomenon of dry wall fouling, make the operation of falling film evaporator energy efficient stable, extended the cycle of operation of falling film evaporator, reduce cleaning frequency, thereby can give full play to the operating characteristic of falling film evaporator efficient stable.
The accompanying drawing explanation
The cutaway view that Fig. 1 is the utility model shower-head type spray distribntor.
The specific embodiment
For technological means, technical characterictic, utility model purpose and the technique effect that the utility model is realized is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Be illustrated in figure 1 a kind of spray distribntor of the shower-head type for falling film evaporator of the present utility model, comprise tank body 100, mount pad 200 and tube sheet 300; Also comprise a shower-head type spray 400; Described tube sheet 300 is located in tank body 100 and this cavity is isolated into to upper chamber 101 and lower chambers 102, is provided with a plurality of overflow pipes 301 on tube sheet 300.
The welding of crown center position or the screw thread of tank body 100 are equipped with mount pad 200, offer one at this mount pad 200 center for placing the installation passage 201 of shower-head type spray 400, offer installing port on the tank body 100 relative with passage 201 is installed, by this installing port, shower-head type can be sprayed to the liquid material of 400 ejections to upper chamber 101.
Head at shower-head type spray 400 of the present utility model is provided with shower nozzle orifice plate 401, and shower nozzle orifice plate 401 is sprayed material over against upper chamber 101.
The applicable more suspended particulate liquid material that contains that contains more suspended particulate liquid material, is assigned with that distributes of the utility model shower-head type spray distribntor main body sprays from shower nozzle orifice plate 401, and shower nozzle orifice plate 401 is to determine the porous plate of aperture and hole count after strict calculating.Below shower nozzle orifice plate 401, be that spray atomizing disperses the liquid point material 402 distributed, liquid point material 402 belows that the spray atomizing that is done disperses have been tube sheets 300 that primary overflow distributes, completing liquid material that primary overflow distributes on tube sheet 300 can form the liquid film that rationally contains uniformly more suspended particulate along the inwall sedimentation of the vertically moving membrane tubulation of falling film evaporator and carry out heat exchange and evaporation and concentration, thereby can guarantee the operation of falling film evaporator stability and high efficiency, fully improved the utilization rate of heat transfer area, reduced the waste of resource and the energy and to the equipment frequent clean and pollution on the environment.
Be only the utility model preferred embodiment in sum, not be used for limiting practical range of the present utility model.Be that all equivalences of doing according to the content of the utility model claim change and modify, all should belong to technology category of the present utility model.
