Description
Technical field
The present invention relates to technical field of heat exchange, more particularly to a kind of shell-and-tube heat exchanger with novel baffle.
Background technology
In shell-and-tube heat exchanger, often install segmental baffle to guide shell-side fluid, avoid short circuit, while in pressure drop permitting
Perhaps accelerate fluid velocity in the range of as far as possible, strengthen the turbulent extent of shell-side fluid, reach the purpose of augmentation of heat transfer.But it is traditional
Segmental baffle still suffer from some problems：1. deflection plate is also easy to produce local flow dead band with housing joint, reduces heat exchange
Efficiency, and easily fouling；2. there is leakage current between deflection plate and shell wall side, not only reduce mainstream speed, and can produce
Larger temperature distortion, it is very unfavorable to conducting heat.3. there is gap between tube bank outermost layer pipe and housing, this gap can produce larger
Bypass leakage current, reduce the mass flow of effective cross-flow tube bank.
The content of the invention
To overcome the shortcomings of that segmental baffle is present, the invention provides a kind of pipe shell type heat exchange with novel baffle
Device, the heat exchanger can not only suppress the formation of flow dead, and in the absence of bypass leakage current, enhance heat transfer effect.
The technical solution adopted for the present invention to solve the technical problems is：A kind of pipe shell type heat exchange with novel baffle
Device, by carrying out sealed housing, the shell side import being arranged in housing sidewall and shell-side outlet, difference by left and right ends end socket
Tube sheet positioned at enclosure interior two ends, the tube side import being arranged on the end socket and tube side outlet, it is arranged on enclosure interior
Two kinds of deflection plates and multiple set of heat exchange tubes being installed in parallel between the tube sheet of two ends are into correspondence is provided with multiple confessions on the tube sheet
The pore that heat exchanger tube is passed through, it is characterised in that：The deflection plate is connection shell side import and the full-circle spray pattern of shell-side outlet and positive six
Two kinds of novel baffles of side shape, it is solid between the outer ledge of full-circle spray pattern and the regular hexagon deflection plate and the inwall of housing sidewall
There is the pore passed through for heat exchanger tube on fixed connection, two kinds of deflection plates.
Described two novel baffles are alternately placed, about at a distance of 60-70mm between each two.
The diameter of the circular deflection plate is equal with housing inner diameter.
The circular deflection plate center is provided with an annulus, and 5-6 times of a diameter of heat exchanger tube diameter of annulus, shell side is situated between
Matter can flow through at annulus.
The length of side of the regular hexagon deflection plate is equal with housing inner diameter, i.e. regular hexagon deflection plate is inscribed in shell side
Portion, shell side medium flows through from gap therebetween.
Three semicircle apertures for being separated by 120 ° are provided with the circular deflection plate edge pore, heat exchanger tube diameter is semicircle
2-3 times of shape hole diameter, the aperture can pass through fraction shell side medium.
Three semicircle apertures for being separated by 120 ° are provided with the pore of the regular hexagon deflection plate center, heat exchanger tube is straight
Footpath is 2-3 times of semicircle hole diameter, can pass through fraction shell side medium.
The housing is cylinder type.
The beneficial effects of the invention are as follows, when shell side medium flows through circular deflection plate and regular hexagon deflection plate, heat exchange area
Reduce, flow velocity increase, shell side medium heat exchanging, which closes to be formed, washes away, and can not only improve heat exchange property, and effectively reduce dirt
Deposition of the dirt on heat exchange tube wall；The semicircle aperture at a distance of 120 ° is provided with two kinds of deflection plates at diverse location, is eliminated
Flow dead so that the media for heat exchange in shell side is uniform.
