Abstract
A kind of improved structure of heat exchanger traverse baffle, the baffling plate body with diversion gap that is arranged on including several in heat exchanger shell, be arranged on baffling plate body be used for wear the heat transfer pore for connecing heat-transfer pipe, breach stagger setting on two neighbouring baffling plate bodys is so as to the formation S-shaped fluid passage in heat exchanger shell, it is characterized in that being provided with deflector on the baffling plate body edge on breach both sides, face and be provided with inlet baffle on the water conservancy diversion plate body edge of breach.Compared with the prior art the present invention, has the advantages of impact for reducing by-pass and heat exchange working media to heat-transfer pipe.
Description
Technical field：The present invention relates to a kind of hot swapping.
Background technology：
As current China faces the problems such as efficiency of energy utilization is low, energy industry equipment falls behind, energy utilization rate needs
Improve, energy-saving potential is huge.Heat exchanger is the important energy consumption equipment in industrial installation, and it constitutes about equipment using energy consumption and given birth to
Produce total energy consumption 14%, and at present shell-and-tube heat exchanger in heat exchanger occupancy volume more than 60%.
At home in whole heat-exchanger products, dividing wall type segmental baffle board heat exchangerses account for more than 80%, wherein, arch folding
Flowing plate is the most frequently used deflection plate form, and shell side is interior to be alternately equipped with some pieces of deflection plates provided with breach, and heat-exchange working medium, which passes through, to be lacked
Mouth gradually crosses deflection plate, therefore deflection plate plays a part of water conservancy diversion, increase heat exchange efficiency.But segmental baffle also exist with
Lower weak point：
Heat exchange working media is horizontally through heating surface bank, on the one hand causes tube vibration, on the other hand, works as fluid flow
Easily the three-dimension fin on heat-transfer pipe is impacted when big, heat-transfer pipe damage is easily caused and fails.
Space between heat exchanger shell inwall and heat-transfer pipe often be present, exchange heat working media flow when have past resistance smaller
Position flowing trend, therefore easily produce the by-pass not occupied for heat-transfer pipe, reduce heat transfer efficiency.
The content of the invention：
The goal of the invention of the present invention is to provide a kind of impact of reduction by-pass and heat exchange working media to heat-transfer pipe
The improved structure of heat exchanger traverse baffle.
The present invention is even achieved in that the baffling with diversion gap being arranged on including several in heat exchanger shell
Plate body, it is arranged on baffling plate body and is used to wear the heat transfer pore that connects heat-transfer pipe, the breach on two neighbouring baffling plate bodys
For stagger setting to form S-shaped fluid passage in heat exchanger shell, it is particular in that the baffling plate body on breach both sides
Deflector is provided with edge, faces and is provided with inlet baffle on the water conservancy diversion plate body edge of breach.During work, the heat exchange of fluid edge
The S-shaped fluid path that deflection plate body is formed in device housing, in the deflector on baffling plate body both sides and the baffle plate of back
Under guide effect, the fluid that lower floor's baffling plate body is come is oriented to above the baffling plate body of upper strata, avoids fluid from producing by-pass, from
And cause the impact to heat-transfer pipe.
Baffling plate body is single bow deflection plate, and heat transfer pore arrangement is symmetrical in wing shape and intermediate region is not provided with conducting heat
Pore.
Baffling plate body parallel arrangement, deflector have four pieces, with being distributed in baffling plate body both sides and pacifying by the way that spot welding is vertical
Mounted in baffling plate body edge, the space effectively filled up between heat pipe and heat exchanger side wall, the working media that prevents from exchanging heat is around heat transfer
Pipe directly passes through baffling plate body.
Compared with the prior art, its advantage is the present invention：
Compared with prior art, the beneficial effects of the invention are as follows：
1st, the space that four deflectors installed on baffling plate body are effectively filled up between heat-transfer pipe and heat exchanger shell side wall,
Prevent heat exchange working media from, by deflection plate, reducing by-pass, relative increases heat exchange area around heat-transfer pipe.
2nd, the arranged situation that baffling plate body uploads heat pipe hole can subtract after optimization while heat transfer efficiency is ensured
The usage amount of few copper pipe, reduces production cost.
3rd, heat exchange working medium inlet flow-stopping plate can reduce impact of the heat exchange working media to heat-transfer pipe, reduce vibration and mill
Damage produces, and forms obvious turbulence effects, can effectively protect the outer boundary layer of heat-transfer pipe, enhancing heat transfer.
Brief description of the drawings：
Fig. 1 is the structural representation of the present invention.
Embodiment：
The present invention is described in further detail in conjunction with drawings and examples：
As illustrated, the present invention includes the baffling plate body with diversion gap a that several are arranged in heat exchanger shell
1st, it is arranged on baffling plate body 1 and is used to wear the heat transfer pore b that connects heat-transfer pipe, the breach a on two neighbouring baffling plate bodys 1
For stagger setting to form S-shaped fluid passage in heat exchanger shell, it is particular in that the baffling plate body on breach a both sides
Deflector 2 is provided with 1 edge, faces and is provided with inlet baffle 3 on the breach a edge of water conservancy diversion plate body 1.
Baffling plate body 1 is single bow deflection plate, is provided with thereon for four positioning rod aperture for installing locating rod 4 and a series of biographies
Heat pipe hole b, the b arrangements of heat transfer pore are symmetrical in wing shape and intermediate region is not provided with the pore that conducts heat.
The parallel arrangement of baffling plate body 1, deflector 2 have four pieces, are evenly distributed on both sides of baffling plate body 1 and vertical by spot welding
Installed in the edge of baffling plate body 1.
