Description
Technical field
This utility model relates to a kind of shell heat exchanger field, is specially a kind of shell side built-in air-flow subaisle structure shell
Formula heat exchanger.
Background technology
Due to maximization and the large of industry shell-and-tube gas-to-gas heat exchanger, the tubulation arrangement of heat exchanger is a lot, gas
Skewness in shell side, reduces heat transfer efficiency, and the biggest impact of heat exchanger diameter is the most serious.And the shell side of heat exchanger
Inlet, outlet nozzle diameter is relatively big, when being connected with other heat exchanger or equipment frequently with connection pipe diameter the biggest；Even
The horizontal range in adapter road is more than the caliber of 3 times, and floor space is relatively big, and the area of dissipation of pipeline is big, and thermal loss is more, with
Shi Guandao and associate member investment cost are big, and operation resistance is high, and therefore large heat exchanger shell side structure form is faced with technological change
Requirement, present maximally effective way is that shell side is divided into the runner that N (instrument size decision) is individual and flows, and gas is by multiple
Circulation road flows to the both sides of tubulation, and the gas after heat exchange flows out from the plane of symmetry of air inlet along circulation road, in gas channel
Adding dividing plate will be into and out of gas partitions.Shell side uses this structure, makes air-flow being evenly distributed at shell side, makes air-flow cross tube bank
Distance drastically reduces, and shell air-flow pressure drop is remarkably decreased；Heat transfer property significantly improves, and reduces heat loss, reduces resistance, saves and throws
Money, trachea shell heat exchanger shell side gas inlet and outlet is bottom in and top out or upper entering and lower leaving, is connected with other heat exchanger or equipment and needs
Wanting long pipe road, floor space is relatively big, and thermal loss is many, invests more, also increases SR.And gas feed be unilateral or
Hoop air inlet, gas arrives tubulation distalmost end, need to flow through cross-sectional distance longer, and along with flowing through the increase of distance, resistance constantly increases
Greatly, for the shaft flow structure shell-and-tube heat exchanger of major diameter, gas is difficult to arrive distalmost end so that heat exchange efficiency drops significantly
Low.
