The purpose of the present invention, technical solution and product advantage are expressed for clarity, and the present invention is done below in conjunction with attached drawing
It is further described.
The present invention provides a kind of half weldering formula plate-type condenser, structure specific embodiment are as follows:
As shown in attached drawing 1-7,10,11:
The condenser includes a frame: by fixed pressure plate 1, top guide bar 2, and lower guide rod 3, movable pressure plate 4,5 groups of pillar
Frame is dressed up, wherein fixed pressure plate 1 is fastenedly connected with top guide bar 2 with bolt part 6；Lower guide rod 3 and fixed pressure plate 1 are used
Bolt part 6 is fastenedly connected；Lower guide rod and movable pressure plate are fastenedly connected with bolt part 6；Pillar and top guide bar spiral shell
Spigot 6 is fastenedly connected.
Including a plate beam: being successively linked into first plate gasket 7, half welding plate piece after fixed pressure plate 1 to (first plate plate to) 8, close
Gasket 9, half welding plate piece are to (Laser Welding fishplate bar to) 10, gasket seal 9, half welding plate piece to (Laser Welding fishplate bar to) 10, sealing
Half welding plate piece of gasket 9 ... is to (Laser Welding fishplate bar to) 10, gasket seal 9, half welding plate piece to (blind plate plate to) 11, blind plate gasket
12, movable pressure plate 4, then plate is compressed to intended size is arrived with fishbolt pair I 13, fishbolt pair II 14, angle steel is installed
Lower margin 15, movable pressure plate support device 16 rivet nameplate 17, medium board 18.
Multiple half welding plate pieces on the plate beam to (i.e. first plate plate to, Laser Welding fishplate bar to, blind plate plate to) 8,10,11 it
Between sealing sealed using gasket seal 7,9,12, while half welding plate piece is between 8,10,11 two plates A and B at sealing
19 use the laser welding structure form of one side welding with back formation, effectively overcome deformation of the plate to welding when, eliminate
The distortional stress of welding.
As shown in attached drawing 3-7,10,11: half welding plate piece on 8,10,11 two plates A and B hot side steam medium into
Mouth end, that is, fat pipe side angle hole large opening φ 700mm.
As shown in attached drawing 8-11: two plate A and B corner apertures opening identical (size, position are identical), veneer plate ripple phase
Instead, corner apertures guiding region is to be formed to two plates of angular flux using the laser welding of one side welding with back formation, steam side Laser Welding
Fishplate bar piece is fat pipe side to chamber (II), is connected between laser welding plate pair with gasket seal and is formed by plate chamber
(I) i.e. the ratio of narrow passage side, fat pipe side circulation area (II) and narrow passage side circulation area (I) is 2:1.
As shown in attached drawing 10-13: the plate is equipped in four corner apertures outer ledges of medium entrance, media outlet to be reinforced
Block 20.The reinforcement number of blocks of optimal selection, each corner apertures is identical, because corner apertures is of different sizes, X-axis of the reinforcement block relative to plate, Y
Axis is in asymmetric arrangement.
The present invention be by two plate A and B sealings with laser welding replace gasket seal form half welding plate piece to 8,10,
11, half welding plate piece of laser welding to without any rubber pad, having at the groove depth of rubber pad by laser welding in 8,10,11 originally
It replaces, therefore this fat pipe side cavity does not contact with any rubber pad, be able to bear high temperature and high pressure steam or corrosive media,
It can be safely operated, can never generate and leak or interior leakage.The steam end medium entrance of two plates A and B use large opening φ
700mm increases the circulation area of steam side medium, reduces flowing velocity, delays the cold and hot media for heat exchange time, reinforce cold and hot medium
Abundant heat exchange, increase heat transfer efficiency.The reinforcement block of φ 700mm is located at plate medium entrance and media outlet at plate large opening
At four corner apertures, reinforcement block improves the fulcrum intensity of heat exchange plate perpendicular to medium entrance and media outlet, asymmetric arrangement,
And then the sealing performance of gasket seal between half welding plate piece pair is promoted, improve half bearing capacity for welding formula plate-type condenser.
The invention has the characteristics that:
1, steam medium import large opening
Steam medium input end, fixed pressure plate large opening φ 700mm, matched pipeline flange are major diameter national standard flange,
Belong to standard configuration flange, convenient and external various piping connections；Hot side plate corner apertures is large opening φ 700mm, although steam
Mass flow is small, but volume flow is big, increases circulation area, reduces flowing velocity, delays the cold and hot media for heat exchange time, reinforces cold
The abundant heat exchange of thermal medium increases heat transfer efficiency.
2, half welding plate piece pair
Two plates A and B are to be open two identical, veneer plate ripple is opposite plates using single face welding and double face with corner apertures
The laser welding of forming forms, and veneer plate A, B are " people " font low-angle ripple, the diagonal flow structure in corner apertures guiding region, plate
Material stainless steel, large opening φ 700mm, machining accuracy is high, and impulse- free robustness shapes；Steam side laser welding plate is to chamber
Room (II) is fat pipe side, is connected between laser welding plate pair with gasket seal and is formed by plate chamber (I) i.e. narrow passage
The ratio of side, fat pipe side circulation area (II) and narrow passage side circulation area (I) is 2:1.Welding uses single side between plate pair
The laser welding of weldering two-sides forming forms, and speed of welding is fast, high-efficient, and welding quality 100% is qualified, and forming is beautiful, using sharp
Photocoagulation heat affected area is small, and welding deformation amount is small, solves the problems, such as to allow heat transfer component that can select compared with thin pieces welding deformation
More relatively thin plate, the thickness the thin more is conducive to heat transfer.
The diagonal flow structure in corner apertures guiding region, to angular flux be exactly refer to steam side medium flowed into from the corner apertures in the plate upper left corner and from
The corner apertures in the lower right corner of plate flows out, and cooling water side medium flows into and corner apertures corner apertures stream from the upper right corner from the corner apertures in the lower left corner
Out, cornerwise type of flow is presented.For heat exchange efficiency, diagonal flow structure can increase flowing of the medium between plate pair
Length, extends the convection current time of cold and hot medium, to increase heat transfer efficiency, and plate can be made full use of to change with diagonal flow structure
Phenomena such as heat area is not likely to produce dead angle, is not likely to produce fouling blockage.Unilateral stream mode is better than to angular flux mode.
3, the reinforcement block of plate tapping
The reinforcement block of plate tapping is located at plate medium entrance and four corner apertures edges of media outlet, and reinforcement block is vertical
In medium entrance and media outlet, asymmetric arrangement improves the fulcrum intensity of heat exchange plate, and then close between half welding plate piece pair of promotion
The sealing performance of gasket improves half bearing capacity for welding formula plate-type condenser.
