Description
Technical field
The invention belongs to heat exchange equipment technology, in particular to a kind of broad passage plate heat exchanger.
Background technique
Plate heat exchanger is higher with its heat exchange efficiency, energy consumption is less, and exchanges heat that direction is reversible is answered extensively in each field
With.Traditional plate heat exchanger be mostly be by square casing and its lumen orientation and to be fixedly welded the plate of connection mostly,
Constitute the thermal medium heat exchange structure alternate with cold medium channel.Although this structure structure is simple, easy to make, when with
When heat exchange containing solid particulate matter or viscous paste medium, media flow excessive velocities, then heat exchanger effectiveness is low, heat exchange
Effect is not satisfactory, and often results in the waste of the energy；If media flow speed is excessively slow, and easily causes and largely adhere on plate inner wall
Heat transferring medium is accumulated, the blocking of heat exchanging medium passage often occurs, maintenance workload is big, influences heat exchange production and heat exchanger
The efficiency used.
Patent CN203550695 discloses a kind of adverse current plate and frame heat exchanger, and structure is that the support of two sides is arranged in
The upper and lower side two sides of plate are respectively welded solid column, and support plate and solid column constitute hollow frame structure, frame structure
It is internally provided with heat exchanger plates beam, front and rear cover plate is flexibly connected with support plate and solid column respectively, the downside of front and rear cover plate and upper
Cold medium export and import is respectively set in side, and partition and anti-short board are provided between front and rear cover plate and heat exchanger plates beam, described
Partition is arranged in anti-short board upper and lower ends, and partition is fixedly connected with support plate, in the heat exchanger plates beam and in the frame knot
The top and bottom of structure are respectively arranged with upper and lower cover plates, and the upper cover plate is provided with thermal medium inlet, and lower cover plate is provided with thermal medium and goes out
Mouthful.Heat exchanger plates beam is to be formed by several plates to group welding, and plate is to being composed of the weldering of two two-phase of plate, then plate pair
Two two-phases are simultaneously.Major defect existing for the technology be its heat exchange rely primarily on mutually and two plates conduction realize, conduction efficiency compared with
It is low, especially when mutually not tight between two plates, there are when gap, thermal conduction effect is influenced even more serious；Secondly, medium
Circulation passage is made of the straight-tube shape inner cavity between the plate being parallel to each other, thus there are foregoing heat exchange efficiency, that is, energy
The problem of utilization rate；In addition, the technology first forms frame structure by support plate and solid column, front and back upper and lower cover plates envelope is then used
Composition heat exchanger shell is closed, maintenance disassembly is still more troublesome.
Summary of the invention
Technical problem to be solved by the invention is to provide a kind of broad passage plate heat exchanger, the heat exchanger heat exchange efficiencies
Height, less energy consumption, and it is easy to maintain.
The technical solution adopted to achieve the above object is as follows: a kind of broad passage plate heat exchanger, including support, shell, change
Hot core, heat exchange medium import and export and heat exchange medium import and export, the heat exchange medium import and export and heat exchange medium into,
Outlet is located on the shell and is connected to heat exchange core body, and the heat exchange core body includes heat exchange medium circulation passage and heat exchange matchmaker
Multiple Wo Zhuan turbulence chamber are arranged in Jie's circulation passage, heat exchange medium circulation passage, and the shell is fabricated structure.
The shell is made of the side plate connection of front and back 4 up and down, and end cap, the heat exchange medium import and export is arranged in both ends
The two-end part of front and rear sides plate is located at heat exchange medium import and export.
The heat exchange core body is made of several heat exchange plates and two sides partition welded connecting, and heat exchange plate is bending-like, and
With the partition plate inserted be welded to connect, partition setting respectively with the heat exchange medium import and export and exchange heat medium import and export
The through-hole of connection.
The heat exchange medium circulation passage and heat exchange medium circulation passage are U-shaped or zigzag loopback configuration
Curved support part is set in the heat exchange medium circulation passage.
The heat exchange medium circulation passage and heat exchange medium circulation passage end use section close for the welding of the packet item of U-shaped
Envelope.
Buffering distributor box is respectively set in the heat exchange medium import and export and heat exchange medium import and export position.
The partition is welded and connected with the charging and discharging drainage cylinder of several and the buffering distributor box cooperation, in drainage cylinder
High molecular abrasion-proof coating is arranged in wall.
Circle distribution pipe buffering grid and several old name for the Arabian countries in the Middle Easts are respectively set in the buffering distributor box.
The heat exchange plate is 2205 two-phase stainless steel board products.
Broad passage plate heat exchanger of the invention mainly has the advantage that
1) heat exchange plate of the heat exchanger uses bending structure, and multiple sections are formed in heat exchange medium circulation passage is
The turbulence chamber of nest shape and the neck of relative narrowness can preferably stabilize temperature gradient of the heat exchange medium on section, work as heat
When exchange media material flows into turbulence chamber by neck, the heat exchange medium material of surface layer and intermediate each layer due to sectional area suddenly
Increase forms turbulent flow and voluntarily seethes stirring, and the heat exchange of each portion's heat exchange medium material in section is accelerated with this；Heat exchange
Medium material, by current stabilization-turbulent flow processes repeatedly, greatly accelerates hot friendship in the flowing in heat exchange medium circulation passage
The efficiency changed.
2) shell of the heat exchanger, buffering distributor box all use fabricated structure, are the installation, maintenance and punching of equipment
It washes maintenance and brings great convenience, thus substantially increase the operation and production efficiency of heat exchanger.
3) in the heat exchanger, heat exchange medium circulation passage and heat exchange medium circulation passage are U-shaped or zigzag winding knot
Structure, and pure counter-flow heat exchange is taken in the flowing of two media, effectively extends the distance that two media carries out heat exchange, and by
This can increase the flow velocity of medium, and general up to 0.9~1.3m/s, high flow rate drives the slurries containing solid particle in plate table
Surface current is dynamic, will not buildup or the blocking that scabs, be effectively prevented the deposition of solid particulate matter or suspended matter in medium, blocking channel,
The generation for phenomena such as wearing heat transfer element is more suitable for the requirement of sandy alumina heat-exchanging process (containing solid particle).
4) heat exchange plate is manufactured using 2205 two-phase stainless steel boards, not only intensity with higher, but also has resistance to height
Temperature resistsSpot corrosionWith cracking corrosion performance and fabulous anti-Stress corrosionThe ability of organic acid corrosion, with austenitic stainless steel phase
Than with apparent advantage, conducive to the increasing widened with pressure for realizing material flow passage, width of flow path can in 1.3m or more,
It is particularly suitable for that extensive, granule materials content is high, corrosivity is strong and the heat exchange of the preferable material of viscosity production.
