Description
Technical field
The heat exchanger of industries such as the utility model relates to and a kind ofly is widely used in generating electricity, oil, chemical industry, particularly a kind of hydroecium of U-shaped pipe shell-and-tube heat exchanger.
Background technology
At present, the high pressure U pipe shell-and-tube heat exchanger hydroecium branch flow process dividing plate of enterprise such as power plant, petrochemical plant application adopts flange combination formula structure usually.Wherein the vertical partition plate with the coaxial setting of heat exchanger adopts and hydroecium integral solder formula structure, and horizontal baffle adopts bolt that dividing plate is connected with semi-circular seal holder ring.What vertical riser, horizontal baffle formed hydroecium inside goes out, goes into water chamber, and purpose is that the water that guarantees to enter in the heat exchanger flows along the U-shaped pipe, and fully heat exchange is so that water reaches the standard temperature rise effect of designing requirement.Through the operation practice, find that the hydroecium dividing plate syndeton of this structure exists deficiency.Because without any sealing filler settings such as pads, therefore being in operation, faying face place that this design flange connects is subjected to the point of attachment that makes between the dividing plate that washes away of high pressure, high flow rate water to be prone to serious brush and to decrease and leak.The water of heating will not take a shorter way (short circuit) by leakage position like this, directly enter high pressure heat exchanger water outlet chamber and flow to the next stage heat exchanger.It is reported that all there is the leakage at this place in the high pressure heat exchanger that many power plant adopt in various degree and influences the water temperature liter, tend to cause final water temperature to descend and reach the adverse consequences more than 20 ℃, significantly reduce the operating efficiency of heat exchanger.In a word, because existing project organization is unreasonable, and processing technology is coarse, makes heat exchanger be difficult to reach every design parameters such as temperature rise, can't reach the result of use of expection.These those skilled in the art once did multiple trial, but effect is all not ideal enough, simply hydroecium being welded as of having is closed, though temporarily solved sealing problem, but increased the repair and maintenance difficulty of equipment,, needed destructiveness to open hydroecium in case go wrong, certainly will prolong the devoting rate level of keeping in repair the duration, reducing heat exchanger to the damage of damaging property of equipment itself.
The utility model content
The purpose of this utility model is to overcome above-mentioned weak point, and a kind of simple in structure, good airproof performance is provided, and is beneficial to the U-shaped pipe shell-and-tube heat exchanger hydroecium of Maintenance and Repair, assurance heat exchange efficiency.
The technical scheme that the utility model adopted is for achieving the above object: a kind of U-shaped pipe shell-and-tube heat exchanger hydroecium, the hydroecium housing one side connection that comprises is provided with the oral siphon assembly, the opposite side correspondence is provided with outlet pipe, and the hydroecium case top is provided with manhole and manhole cover, is formed into water chamber in it; The hydroecium housing inboard of corresponding outlet pipe is provided with semi-circular seat ring, and be located by connecting vertical partition plate and horizontal baffle, vertical partition plate and horizontal baffle with and surround under the water outlet chamber of part hydroecium inner walls formation be communicated with the outlet pipe of hydroecium housing; The hydroecium housing bottom is provided with the tube sheet of corresponding connection with heat exchanger U-shaped pipe; It is characterized in that fixedlying connected with the inwall of hydroecium housing outside the seat ring; The spacing overlap joint of horizontal baffle piecemeal, the upper surface of described horizontal baffle lap-joint are provided with sealing with pad or offer packing groove, are provided with the sealing filler in it; Equally, the seat ring upper surface that is connected with horizontal baffle is provided with sealing with pad or offer packing groove, is provided with the sealing filler in it; Horizontal baffle lap-joint and seat ring and horizontal baffle junction are respectively equipped with set bolt; Described set bolt is positioned at the bottom overlap with horizontal baffle and adopts welded seal to be connected.
The beneficial effects of the utility model are: by adding hermetically-sealed construction, the set-up mode and the fixed form that comprise the overlap joint interface set bolt between horizontal baffle, favorable sealing property, can make its abundant heat exchange, reach the water temperature liter of design, significantly improve the operating efficiency of heat exchanger, and guarantee that heat exchanger is reliable.Its structural design is simple, makes simple installation, and repair and maintenance is convenient, reduces labour intensity, has wide range of applications.
