Abstract
The invention relates to a connecting device among heat exchange tubes of a multi-effect evaporator. The device comprises upper and lower connectors, wherein the upper and lower ends of each connector are connected with the heat exchange tubes of the evaporator in a matched mode; a gradually reducing section, a throat mouth section and an expansion section are arranged between the upper and lower connectors in turn; and the cross sectional area of the connecting device in the gradually reducing section is gradually reduced, the cross sectional area of the connecting device in the expansion section is gradually increased, and the area of the throat mouth section is smaller than the area of the gradually reducing section and the area of the expansion section. The gradually reducing and gradually expanding structure of the gradually reducing section, the throat mouth section and the expansion section is skillfully used, and a small number of materials are used, so that the bias flow phenomenon after steam is turned 180 degrees is avoided, and the problem of steam inlet non-uniformity is solved; and equipment performance is improved, the materials are saved and occupied space is reduced simultaneously.
Description
Technical field
The present invention relates to a kind of jockey, particularly relate to the jockey between a kind of multi-effect evaporator heat exchanger tube.
Background technology
Multiple-effect steam distillation evaporimeter (MED) is a multiple-effect evaporation, is connected by a plurality of evaporimeters to form.General existing multi-effect evaporator is single-row layout, and all evaporators links to each other with the straight section shell ring in order and between imitating.The evaporimeter of Bu Zhiing like this, if arrange that to imitate number more, length will be very long, can not satisfy the requirement of flexible arrangement.
Therefore, the permutation device length under the existing multi-effect evaporator arrangement is all long usually, and floor space is excessive.If with elbow multi-effect evaporator is interconnected and to carry out multiple row and arrange, then can have following defective:
1. steam flow the bias current phenomenon occurs owing to turning in the elbow, can not evenly enter in the tube bank of evaporimeter when steam enters lower effective evaporator, causes condensation heat transfer inhomogeneous, influences the evaporimeter heat exchange property;
2. connect the whole latus rectum of elbow diameter and evaporimeter, waste material also takies more space simultaneously.
For, according to hydromechanical principle,, reach on the basis of less use material by design steam flow passage, it is even to reach the assurance steam flow, the purpose that heat transfer property is good.
Summary of the invention
The objective of the invention is to, overcome the defective of above-mentioned prior art and provide a kind of and solve that evaporimeter connects that steam bias current in 180 ° of elbows causes that the evaporimeter admission is inhomogeneous, the jockey between multi-effect evaporator heat exchanger tube that condensing heat-exchange poor-performing and elbow material use more, waste of material problems of too.
For achieving the above object, the present invention takes following design:
Jockey between a kind of multi-effect evaporator heat exchanger tube, comprise the connector that matches and be connected in up and down two ends and evaporimeter heat exchanger tube, between last lower union joint, comprise converging transition, aditus laryngis section and diffuser successively, wherein said jockey reduces gradually at described converging transition cross-sectional area, cross-sectional area at described diffuser increases gradually, at the cross-sectional area of described aditus laryngis section less than converging transition and diffuser cross-sectional area.
Preferably, smooth connection between the inwall of described converging transition, aditus laryngis section and diffuser.Further, the cross-sectional area of described aditus laryngis section is 25～45% of a described connector cross-sectional area.
Preferably, described aditus laryngis section is positioned at the centre position of converging transition and diffuser, and described converging transition and diffuser are with respect to described aditus laryngis section and are symmetrical arranged.
Advantage of the present invention is: because the present invention has utilized the structure of converging transition, aditus laryngis section and diffuser convergent flaring, and utilized less material, the bias current phenomenon of steam after half-turn eliminated, solve the problem of steam bias current after the half-turn thus, prevented steam admission non-uniformity problem; And improved equipment performance, also save material simultaneously, reduced floor space.
Description of drawings
Fig. 1 is applied to structural representation in evaporimeter for the present invention;
Fig. 2 is the right view of structure shown in Figure 1.
The specific embodiment
Referring to Fig. 1～Fig. 2, the preferred embodiment of the jockey between a kind of multi-effect evaporator heat exchanger tube of the present invention shown in it, comprise the connector 1 that matches and be connected in up and down two ends and evaporimeter heat exchanger tube 6,2, this connector 1,2 diameter matches with the diameter of described evaporimeter heat exchanger tube 6, at last lower union joint 1, comprise converging transition 3 between 2 successively, aditus laryngis section 4 and diffuser 5, wherein said jockey reduces gradually at described converging transition 4 cross-sectional areas, cross-sectional area at described diffuser 5 increases gradually, at the cross-sectional area of described aditus laryngis section 4 less than converging transition 4 and diffuser 5 cross-sectional areas.Preferably, smooth connection between the inwall of described converging transition 3, aditus laryngis section 4 and diffuser 5.Thus, make the fluid in the heat exchanger tube 6 can be subjected to littler resistance.
Preferably, the cross-sectional area of described aditus laryngis section 4 is 25～45% of described connector 1,2 cross-sectional areas.In the present embodiment, the cross-sectional area of described aditus laryngis section 4 is 30% of described connector 1,2 cross-sectional areas.That is, reach the minimum of a value of caliber in half-turn place, this minimum of a value is 30% of heat exchanger tube 6 diameters.
Further, as shown in Figure 2, described aditus laryngis section 4 is positioned at the centre position of converging transition 3 and diffuser 5, and described converging transition 3 and diffuser 5 are with respect to described aditus laryngis section 4 and are symmetrical arranged.Thus, the steam exit at last 1st effective evaporator is provided with converging transition 3, reaches the caliber minimum of a value in half-turn place, is aditus laryngis section 4, and after turning over this angle, jet size is flaring progressively, is diffuser 5, up to being connected with following 1st effective evaporator air intake.In principle, the systolic pressure of convergent flaring structure of the present invention is identical with expansion pressure, under the condition of not considering crushing, and front and back pressure unanimity.The present invention is and utilizes this kind principle, has reached the even combing effect of steam, has guaranteed the uniformity of evaporimeter steam admission.
Obviously, those of ordinary skill in the art can constitute various types of jockeys with the jockey between a kind of multi-effect evaporator heat exchanger tube of the present invention.
The foregoing description is only for the usefulness that the present invention is described; and be not to be limitation of the present invention; the those of ordinary skill in relevant technologies field; without departing from the present invention; can also make various variations and modification; therefore all technical schemes that are equal to also should belong to category of the present invention, and scope of patent protection of the present invention should be limited by each claim.
