Description
Technical field
It the utility model is related to the detection means of a kind of oily salt heat exchanger tube head leakage or booster.Mainly for detection of operation
During oily salt heat exchanger exchanger tubes and tubesheets jointing whether leak or heat exchanger tube whether booster.
Background technology
Oily salt heat exchanger is the important component in photo-thermal power generation power station, and its effect is the heat for collecting solar energy light field
Amount is delivered to the steam generating system in generating set, so as to provide energy for whole power station.Daytime, fused salt are absorbed by light field
Rear portion to solar energy is stored into fused salt tank, and a part is transported to oily salt heat exchanger heating conduction oil, and heated leads
Deep fat is transported to steam generating system again, produces the steam of HTHP, and then pushing turbine drives whole generating set
Operation；At night, then oily salt heat exchanger is transported to by the fused salt for extracting storage on daytime in fused salt tank out, continues this energy conversion.
As can be seen here, the safe operation of oily salt heat exchanger is very crucial for photo-thermal power generation power station, but due to fortune
Row operating mode is more severe, and oily salt heat exchanger not only needs to bear high temperature, and at least also needs to bear cyclic loading twice daily,
So oily salt heat exchanger tube sheet is also easier to produce leakage with heat exchange pipe joint, if can not find to repair in time, it will make
Cheng Geng great potential safety hazards.
The content of the invention
The purpose of this utility model is to provide the detection means of a kind of oily salt heat exchanger tube head leakage or booster, can be in oil
Salt heat exchanger running find in time the jointing of exchanger tubes and tubesheets whether leak or heat exchanger tube whether booster, concurrently
Accidents happened signal, interlocking action signal is provided for overpressure protection system.
The technical scheme in the invention for solving the above technical problem is：A kind of oily salt heat exchanger tube head leakage or booster
Detection means, the piston for being integrated with upper and lower end self-tightening sealing structure and radial direction expansion ring seale structure is placed in lower cylinder barrel, and is put
Spring assembly in upper cylinder barrel is then interacted by piston rod and piston, then can be in as between upper and lower cylinder barrel
Between cut-off distinguish, but the hole on separating can keep the connection between upper and lower cylinder barrel, with the fused salt side of oily salt heat exchanger and
The signal port of conduction oil side connection is separately positioned on upper and lower cylinder barrel；It is arranged on the magnet of piston and is arranged on lower cylinder barrel
The magnetic switch of outer wall together constitutes signal transmission structure；The blowdown and exhaust of device can be upper and lower by being arranged on device
The adapter at end is realized.
In addition along with the upper and lower support on cylinder barrel just constitutes whole detection means.
Compared with prior art, the utility model has the advantage of：
It can find whether the jointing of exchanger tubes and tubesheets leaks or change in time in oily salt heat exchanger running
Heat pipe whether booster, concurrent accidents happened signal, interlocking action signal is provided for overpressure protection system.
Brief description of the drawings
Fig. 1 is the leakage of oily salt heat exchanger tube head or booster detection means basic functional principle figure；
Fig. 2 is the leakage of oily salt heat exchanger tube head or booster structure of the detecting device figure.
Wherein：
Upper cylinder barrel 1, lower cylinder barrel 2, spring assembly 3, piston rod 4, piston 5, magnet 6, magnetic switch 7, conduction oil side signal
Connector 8, sewage draining exit 9, fused salt side signal connector 10, exhaust outlet 11, upper support 12, lower support 13.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing embodiment.
As shown in figure 1, the detection means of a kind of oily salt heat exchanger tube head leakage or booster in the present embodiment, it includes living
Plug structure, piston upper end self-tightening sealing structure, piston radial expansion ring seale structure, piston sealing structure, signal transmission knot
Structure, spring assembly, upper and lower cylinder structure and signal connector etc..
The piston 5 for being integrated with upper and lower end self-tightening sealing structure and radial direction expansion ring seale structure is placed in lower cylinder barrel 2, and is put
Spring assembly 3 in upper cylinder barrel 1 is then interacted by piston rod 4 and piston 5, as between upper and lower cylinder barrel, then can be led to
Middle cut-off is crossed to distinguish, but the hole on separating can keep the connection between upper and lower cylinder barrel, the fused salt with oily salt heat exchanger
Side is separately positioned on upper and lower cylinder barrel with the signal port that conduction oil side connects；It is arranged on the magnet 6 of piston and is arranged on down
The magnetic switch 7 of cylinder barrel outer wall together constitutes signal transmission structure；The blowdown and exhaust of device can be by being arranged on device
The adapter of upper and lower end is realized, in addition along with the upper and lower support on cylinder barrel just constitutes whole detection means.
A kind of oily salt heat exchanger tube head leakage or the detection method of booster, conduction oil side signal connector, fused salt side signal
Connector connects with oily salt heat exchanger conduction oil side, fused salt side respectively, when normal operation, the pressure ratio fused salt side of conduction oil side
Pressure is much higher, so piston can be moved to lower cylinder barrel top under differential pressure action；When oily salt heat exchanger tube head is revealed or is changed
During heat pipe booster, the conduction oil of conduction oil side can largely leak into fused salt side, so as to cause the pressure of both sides to tend to be identical, support
The pressure differential collapses of piston, piston quickly move down under the action of the spring, and the magnetic switch for being now arranged on certain position will
The signal of piston movement is captured, whether there occurs leakage accident so as to judge fuel-displaced salt heat exchanger；And it is arranged on piston
Upper and lower self-tightening sealing structure and radial direction expansion ring seale structure may insure whenever the medium of conduction oil side and fused salt side not
It can be leaked by detection means.
In addition to the implementation, the utility model also includes other embodiment, all to use equivalents or equivalent
The technical scheme that substitute mode is formed, all should fall within the protection domain of the utility model claims.
