Description
Technical field
The utility model is related to Heat Transfer Performance of Shell-and-tube Heat Exchanger research field, more particularly to a kind of to pipe shell type heat exchange
Device tube side fluid carries out the device of temperature survey.
Background technology
Shell-and-tube heat exchanger is simple in construction, and operation is reliable, is mainly manufactured, can be used under high temperature, high pressure by metal material,
It is one of heat exchanger types most widely used at present, is particularly widely used in fields such as energy recovery, generatings.Its structure is,
Heat-transfer surface is used as using the tube bank wall of closing in the housing.This structure brings very big tired to fluid temperature (F.T.) measurement in heat exchanger
Difficulty, so carrying out temperature survey to shell-and-tube heat exchanger fluid at present is mainly limited to heat exchanger fluid import and export.But, survey
Buret shell heat exchanger internal flow Temperature Distribution optimizes the operating mode selection of heat exchanger, changed to the heat exchange property of research heat exchanger
The design materials selection of hot device is all most important.
The structure of shell-and-tube heat exchanger limits the temperature of the direct measurement of its internal flow temperature, particularly tube side fluid
Measurement.Existing method is typically that the distribution of shell-and-tube heat exchanger fluid temperature (F.T.) is studied, it is necessary to find one using numerical simulation
Plant measuring method and experimental verification is carried out to numerous analog results.
Shell-and-tube heat exchanger internal flow is divided into shell-side fluid and tube side fluid, therefore internal flow Temperature Distribution is also classified into
Shell-side fluid temperature is distributed and tube side fluid Temperature Distribution.It is existing that method measured directly is carried out to shell-side fluid temperature,
Punching insertion thermocouple or thermal resistance on shell-and-tube heat exchanger housing, this method due to needing to destroy housing, heat exchanger it is close
Envelope is difficult to ensure that, it is impossible to be used in high pressure operating mode.
Publication No. CN103674310A patent mentions a kind of fuel temperature measurement method based on oil pipe surface temperature measurement,
This method is not the direct measurement to fluid temperature (F.T.), and if applied to pipe for shell-and-tube exchanger journey fluid, need to destroy heat exchange
Device housing.Publication No. CN204679181U patent mentions a kind of tube fluid pressure and temperature while the fiber grating measured
Sensor, the measuring method needs to destroy fluid line, because shell-and-tube heat exchanger heat transfer pipe diameter is small and is wrapped up by shell, no
Suitable for the measuring method.Publication No. CN104697739A patent mentions cryogen flowing resistance in a kind of adiabatic bellows
Fluids within pipes can be carried out temperature survey, but be not suitable for shell-and-tube heat exchanger by power and Temperature Distribution test device.Paper
Mainly it is divided to two kinds Deng the fluids within pipes temperature preparation method mentioned in document：Measure tube wall temperature and then derive fluid temperature
Degree；Destruction pipeline puts in thermocouple or thermal resistance measurement fluid temperature (F.T.).If both approaches are used for pipe for shell-and-tube exchanger
The measurement of journey fluid temperature (F.T.), the former needs destruction housing and derives that error is larger, and the latter, which not only breaks up housing and also needs to destruction, to be changed
The heat exchanger tube and difficult arrangement of hot device.
