Larger industrial enterprise is usually larger with thermal power, is needed using the heat exchange equipment of steam heating conduction oil more
Group is common to be completed, and the reliability of system heat supply can be improved in this heat-supplying mode.But the increasing to also increase of heat exchange equipment is changed
The probability of hot device failure.Since the hot and cold medium in heat exchange equipment is usually conduction oil and steam/water, in the operating condition
Steam/water and conduction oil temperature usually with higher and pressure.Swiftly flowing heat transferring medium may cause abrasion, vibration
Phenomena such as, permanent operation may result in the leakage of heat exchange equipment.
Therefore how monitoring running state is carried out to the heat-condutive oil heat exchanger equipment of multiple groups parallel connection, is let out existing for discovery in time
Leak out danger, and be isolated to system, overhauled etc. is the essential condition for guaranteeing system safety operation.
Summary of the invention
The technical problem to be solved in the present invention: providing a kind of leakage monitoring system suitable for heat-condutive oil heat exchanger,
Installation is used for the sensor of vibration and noise signal capture, letter of the sensor acquisition respectively on the multiple row heat exchanger of heating system
Number it is transmitted to Multi-channel signal analysis system, Signal Analysis System is built-in with Data Analysis Software, by vibration, noise signal
Spectrum analysis and trend compare, judge whether the heat exchanger of corresponding channel is in normal operating conditions, then analysis result
It is shown in monitoring terminal.If there is the heat exchanger of abnormal work, alarm signal is sent to monitoring personnel by system, when necessary
The heat exchanger cold heat fluid import/export valve is closed, failure heat exchanger is isolated from operating system.
The present invention solve above-mentioned technical problem the technical solution adopted is that: it is a kind of be adapted to heat-condutive oil heat exchanger leakage prison
Examining system, it is characterised in that: including steam boiler system, multiple row heat exchanger, feed pump, vibration and noise sensor and multichannel
Signal Analysis System, each column heat exchanger include heat conductive oil inlet valve, conduction oil outlet valve, steam inlet valve and condensation water out
Valve, the high parameter steam that steam boiler system generates enter the heat exchanger being connected in parallel by steam, transfer heat to thermally conductive
The oil condensation of steam generation simultaneously, condensed water are discharged by condensed water outlet valve；The lower conduction oil of temperature absorbs what steam was released
Heat becomes high temperature heat conductive oil, then is transported to Process heat；It is arranged with vibration and noise sensor on each heat exchanger, is
The signal being collected into is passed to Multi-channel signal analysis system, Multi-channel signal analysis by vibration and noise sensor when system work
System carries out spectrum analysis and judgement by the built-in working condition for analyzing software heat exchanging device, if event occurs for certain column heat exchanger
Barrier, then system can send out alarm signal to monitoring personnel automatically, or directly close heat conductive oil inlet valve, conduction oil outlet valve, steam
Inlet valve, condensed water outlet valve, are isolated failure system.
The advantages of the present invention over the prior art are that:
Relative to traditional heat-conducting oil heating mode, the heat-supplying mode that steam heats conduction oil has safe and efficient spy
Point, therefore this kind of product more and more can be applied in industry heating field.It is suitable for conduction oil the present invention provides one kind to exchange heat
The leakage monitoring system of device can be convenient and realize that the on-line monitoring of heat-condutive oil heat exchanger operation is sentenced by signal collection and analysis
Whether each column heat exchanger that breaks is in normal operating conditions, and failure system can be carried out Rapid Alarm be isolated.
Detailed description of the invention
Fig. 1 is the schematic illustration of the present invention in the normal mode of operation.
In figure: 1 is steam boiler system, and 2 be heat exchanger, and 21 be steam inlet valve, and 23 be condensed water outlet valve, and 22 be to lead
Hot oil inlet valve, 24 be conduction oil outlet valve, and 3 be feed pump, and 4 be vibration and noise sensor, and 5 be Multi-channel signal analysis system
