Description
Technical field
The utility model is related to technical field of heat exchangers, and in particular to one kind being used for fluid heat exchanger containing solid particle.
Background technology
In fields such as petrochemical industry, metallurgy, electric power, environmental protection, a kind of clean fluid and a kind of solid particle fluid heat transfer that contains are special
Not common operating mode, if the station selects traditional arch shape traverse baffle shell type heat exchanger, due to exist in the middle part of tube bank compared with
Large-scale dead zone, in the During Process of Long-term Operation of equipment, solids particles precipitate fouling is serious on tube wall, heat exchanger heat exchange efficiency
Decline, need frequent parking maintenance, by tube bank extraction cleaning, influences the normal production run of whole device.
What is more often selected at present is helical deflecting plate pipe and shell type heat exchanger and spiral heat exchanger.Helical baffles shell
Formula heat exchanger makes shell-side fluid that helical flow be presented by the supporting way of change baffle plate, and circulation is formed in tube bank periphery,
Reduce tube bank minimal internal dead space range, to extend the cleaning during shutdown period.For helical deflecting plate pipe and shell type heat exchanger, although improving shell
Journey Flow Field Distribution situation, but do not solve the problems, such as that there are flow dead zones at tube bank middle part fundamentally, while fluid containing solid particle
Heat-exchanging tube bundle is crossed, there is larger souring to tube bank, influence the security reliability of equipment.
Spiral heat exchanger have compact-sized, efficient, Flow Field Distribution uniformly, solid particle should not deposit fouling,
But the equipment operation pressure and temp cannot be too high, while checking maintenance difficulty is big, can the extent of spreading amd application it is narrow.
Utility model content
The utility model provides a kind of fluid heat exchanger containing solid particle, solves traditional shell-and-tube heat exchanger containing solid
In body granule fluid heat transfer process, heat-exchanging tube bundle is also easy to produce erosion and granular solids deposition, influences Heat Exchanger Reliability and heat transfer
The problem of performance.
The utility model solve above-mentioned technical problem technical solution be：
One kind being used for fluid heat exchanger containing solid particle, including bobbin carriage, tube bank, shell, the bobbin carriage, shell, conical shell structure
It is sequentially connected composition vertical heat exchanger shell, restrains and is arranged inside housings for the U-tube beam of rod baffle；It is described tube bank by
The baffle ring composition of tube sheet, the U heat exchange mounted on tube sheet and support heat exchanger tube；And baffle ring by ring and is fixed on ring
Several parallel rod baffle compositions.
The mode of baffle ring support heat exchanger tube is：When heat exchanger tube arranged in squares, adjacent four groups of baffle rings
Rod baffle respectively puts to form square structure and heat exchanger tube is centered around in the square structure at an angle of 90 degrees, to make heat exchanger tube
Four supporting points are obtained to fix.
The mode of baffle ring support heat exchanger tube is：When heat exchanger tube triangular arrangement, adjacent four groups of baffle rings
Rod baffle puts to form diamond structure and heat exchanger tube is centered around in the diamond structure with an angle, to make heat exchange be in control four
A supporting point is fixed.
Clean fluid walks tube side in the utility model, and fluid containing solid particle walks shell side.Under fluid containing solid particle is enterprising
Go out, flowed in the housing along heat exchanger tube axial direction, fluid flow direction is identical as solid particle dirt drop direction, reduces solid
Grain deposits and exchanges washing away for heat pipe.Using rod baffle baffling, rod baffle is that point supports with heat exchanger tube, for particle in tube bank
The sectional area of deposition is small, and the contact point fluid-flow mode is to stream, and has automatic cleaning action.The flow field of heat exchanger shell pass
It is evenly distributed, flow regime is identical around every heat exchanger tube, without flow dead zone.U-shaped crook shell cover is set as conical shell, stream
Flow velocity increases the flow area of body from large to small, can accelerate the discharge of the fluid containing solid particle, reduces tube bank and produces in the position
The probability of raw particle deposition.It fundamentally solves to wash away tube bank, easy scale effect in heat transfer process containing solid particle fluid
The problem of heat exchanger heat transfer efficiency and reliability.
The utility model can be used for a kind of clean fluid in the fields such as petrochemical industry, metallurgy, electric power, environmental protection and contain solid with a kind of
Grain fluid heat transfer occasion.
