Description
Technical field
This utility model belongs to technical field of heat exchangers, relates to a kind of kettle type reboiler for multi-fluid heat exchange.
Background technology
At present, multi-fluid kettle type reboiler can be divided into two kinds, and one is multi-fluid fixed tube sheet type kettle type reboiler.Another kind is multi-fluid U-tube formula kettle type reboiler.
Multi-fluid fixed tube sheet type kettle type reboiler compact conformation, floor space are little, but absorption tube shell-side fluid thermal (temperature difference) stress ability is little.Existing multi-fluid U-tube formula kettle type reboiler can absorb shell journey fluid temperature difference stress, but respectively restraining the most independent in housing layout, heat transfer efficiency is low, tube sheet not stringing area big, tube sheet thermo parameters method is uneven, structure is complicated, metal consumption is high, floor space is big.Additionally, the thermal (temperature difference) stress that existing many logistics kettle type reboiler hot-fluid entrance point tube sheet and dividing plate are caused by a plurality of fluids skewness is bigger.
Utility model content
This utility model provides a kind of multi-fluid kettle type reboiler, can effectively reduce tube sheet and the thermal (temperature difference) stress of dividing plate that a plurality of fluids skewness causes, for multi-fluid boiling heat transfer.
The purpose of this utility model has the technical scheme that
A kind of multi-fluid kettle type reboiler, including overall bobbin carriage and autoclave housing, it is tightly connected by tube sheet between the two, the upper end of described autoclave housing is provided with vapor phase exit, and its underpart is sequentially provided with cold flow import and liquid-phase outlet, described overall bobbin carriage is separated into several chamber by bobbin carriage dividing plate, neighbouring chamber forms sub-thread hot-fluid bobbin carriage, the corresponding one group of U-shaped heat-exchanging tube bundle of each sub-thread hot-fluid bobbin carriage, each group U-shaped heat-exchanging tube bundle is combined into overall U-shaped heat-exchanging tube bundle, the heat exchanger tube of this entirety U-shaped heat-exchanging tube bundle is evenly arranged on described tube sheet, it is provided with hot-fluid import and hot outlets on described each sub-thread hot-fluid bobbin carriage.
Described each sub-thread hot-fluid import bobbin carriage is equipped with heat flux distribution device.
This utility model compact conformation, heat transfer efficiency is high, tube side fluid is evenly distributed, can effectively reduce the thermal (temperature difference) stress of tube sheet and the dividing plate caused by a plurality of fluids skewness, U-shaped heat-exchanging tube bundle fully absorbs housing and interbank thermal (temperature difference) stress, it is possible to resolve existing multi-fluid kettle type reboiler heat transfer efficiency is low,
Floor space is big, tube sheet and the difficult problem such as heat exchanger tube joint thermal (temperature difference) stress is big.
This utility model is safe and reliable, metal consumption is low, floor space is little.
