Abstract
The utility model relates to a lengthened overflow groove type film distributing device which comprises a film distributing pipe and a falling film pipe. The falling film pipe is arranged at the lower part inside the film distributing pipe; the depth that the film distributing pipe is inserted into the falling film pipe exceeds the lower part of an expanded pipe of the falling film pipe; and the middle part of the film distributing pipe is provided with a plurality of slotted holes along the film flow direction. In the utility model, the film distributing device is arranged at the falling film pipe of an upper tube plate at the upper part of a falling film evaporator; the film distributing pipe is lengthened, so that the depth that the film distributing pipe is inserted into the falling film pipe is greater than the length of the expanded pipe; a mode of slotting a tangential elongated slot is adopted to form a tangential opening; with the adoption of the lengthened overflow groove type film distributing device, the influence that a falling liquid film is deviated from the inner wall of the falling film pipe can be prevented from being caused due to the expanded pipe part; meanwhile, due to the tangential elongated slot, the opening of a lower port of the elongated slot can be avoided being influenced by pipe insertion and spot welding; and therefore liquid phase can uniformly enter the falling film pipe.
Description
Technical field
The utility model relates to the chemical industry evaporimeter that adopts falling liquid film technology to concentrate, and is a kind of film-distributing device in the falling film evaporator.
Background technology
Falling film evaporator is imported different medium respectively in the shell journey, realize the heat exchange of medium through the falling liquid film tube wall.After by the entering upper perforated plate of the liquid phase medium uniform and stable that concentrates, must carry out cloth film uniformly and effectively through making the film device.The tradition filming device generally is fluting or following open flume type; The influence that this mode of grooving very easily receives external factor makes the uneven cloth film effect that influences of fluting; Traditional filming device all is set to more than the expand tube part simultaneously, because of expand tube partly is a concave structure, very easily liquid film is exerted an influence; Make liquid film go out the tube wall of falling liquid film pipe, influence evaporation effect greatly.
Summary of the invention
The purpose of the utility model is, proposes a kind of extended pattern overflow slot type and makes the film device, can eliminate expand tube and the influence of welding to the cloth film, thereby improves cloth film effect.
The technical scheme of the utility model: a kind of extended pattern overflow slot type is made the film device; Comprise and make film pipe and falling liquid film pipe; The bottom of making in the film pipe is an expand tube for the falling liquid film pipe, makes the film pipe and inserts the expand tube bottom that the falling liquid film pipe degree of depth surpasses the falling liquid film pipe, in the middle part of making the film pipe, opens the tangential long slot bore.Film device bottom is made in prolongation makes the length of making the film device be longer than the lower horizontal part 3mm of expand tube.Mode of grooving has some long slot bores that flow to (tangential) along film in the middle part of being employed in and making the film device.
The operation principle of the utility model is following: traditional filming device generally is fluting or following open flume type; The influence that this mode of grooving very easily receives external factor makes groove width wide at the top and narrow at the bottom or narrow down wide; Influence the uniformity that liquid gets into the falling liquid film pipe; Adopt the tangential long slot bore at the middle part of making the film device, just can be when intubate or spot welding because of the stressed but long slot bore distortion in outside.Traditional filming device all is set to more than the expand tube part simultaneously; Because of expand tube partly is a concave structure, very easily liquid film is exerted an influence, make liquid film go out the tube wall of falling liquid film pipe; Influence greatly evaporation effect; Prolong make film device bottom make make the film device length greater than expand tube part 3mm after, liquid phase just can avoid causing owing to expand tube the influence of concave structure, liquid can very steadily descend along the falling liquid film pipe uniformly.
The utility model beneficial effect is: the utility model is that the film device is made in the setting of upper perforated plate falling liquid film pipe place on falling film evaporator top, and the utility model is made the film pipe through prolongation, makes and makes film pipe insertion depth above the expand tube part, and the tangent line opening adopts the tangential elongated slot mode of opening.The utility model is made the film device through this extended pattern overflow slot type, can prevent that the expand tube part from producing the influence that departs from the falling liquid film inside pipe wall to the liquid film that descends.Simultaneously the tangential elongated slot can avoid influencing because of intubate and spot welding the aperture of elongated slot end opening.Liquid phase can be got in the falling liquid film pipe uniformly.
Description of drawings
The novel film device of making of Fig. 1
Make film pipe 1, tangential elongated slot 2, falling liquid film pipe expanded joint position 3, liquid film among the figure and steadily drop to inside pipe wall 5.
The specific embodiment
Specify the embodiment of the utility model below:
Through accompanying drawing the utility model can be described, the utility model is to open tangential long slot bore 2 at the middle part of making the film device, and when the blanking of film device is made in processing, considers the length of expand tube part, makes to make the inner length of film device 1 insertion falling liquid film pipe greater than expand tube bottom 3mm.
Select the bar or the tubing (wall thickness will meet) of suitable size; Make the film pipe of making of making the film device be processed into taper through machining with the part surface that the falling liquid film pipe contacts; The top caliber is greater than making film pipe size, and the bottom caliber is slightly less than makes film pipe size, make make the film device can be to insert in the falling liquid film pipe.The film pipe inside and outside wall of making after processing is answered smooth zero defect; After making 1 moulding of film device, on the middle part, open tangential long slot bore 2 again; Fall after other all complete at evaporimeter and make in the film device insertion falling liquid film pipe 3; Make and make the film device and slightly be longer than about the bottom 3mm of falling liquid film pipe expanded joint part, and then make the levelling of film device and 3 spot welding of falling liquid film pipe are fixed all.
Claims (2)
1. extended pattern overflow slot type is made the film device, it is characterized in that comprising making film pipe and falling liquid film pipe, and the bottom of making in the film pipe is the falling liquid film pipe, makes the film pipe and inserts the expand tube bottom that the falling liquid film pipe degree of depth surpasses the falling liquid film pipe, in the middle part of making the film pipe, opens some long slot bores that flow to along film.
2. extended pattern overflow slot type according to claim 1 is made the film device, it is characterized in that prolonging making film device bottom and making the length of making the film device be longer than the lower horizontal part 3mm of expand tube.
