Description
Technical field
The present invention relates to a kind of heat exchanger antiscaling and descaling device, more particularly to a kind of plate type heat exchanger are anti-with online ultrasonic wave
Dirty apparatus for eliminating sludge.
Background technology
Plate type heat exchanger industrial production or it is civilian in be used for realize two kinds of materials between heat transfer equipment, production
In running, recirculated water heat easily produces scale formation on heat exchange plate, because the thermal conductivity factor of dirt is far below heat exchange
The thermal conductivity factor of plate, therefore the attachment of dirt greatly reduces the heat exchange efficiency of heat exchanger, while adding cooling circulating water
The resistance to water-flow of system, adds the energy consumption of water circulating pump；Dirt easily produces underdeposit corrosion on heat exchange plate even to be made to change
Hot plate piece is perforated or ruptured, and has a strong impact on equipment operation.
Currently for more than plate type heat exchanger scale problems using the processing method chemically or mechanically cleaned.Chemical cleaning method
Major defect be that chemical cleaning solution is unstable, heat exchanging device can produce corrosion, and the emission after cleaning is polluted to environment；
Mechanical cleaning method is first to take out heat exchange plate, is immersed in different liquid, makes dirt maceration, loosening, then with machinery
Method is except de-sludging layer, then cleaned heat exchange plate is installed onto on heat exchanger, and this cleaning method needs could when shutting down
Carry out.
The content of the invention
In order to overcome the defect in above-mentioned cleaning method, the present invention provides a kind of online ultrasonic scale prevention of plate type heat exchanger
Apparatus for eliminating sludge.
Technical program of the present invention lies in：Including ultrasonic generator, through being brought into close contact in heat exchange plate for plate heat exchanger piece side
The ultrasonic transducer that the ultrasonic wave guide plate on side is connected with plate type heat exchanger；Each ultrasonic wave guide plate is provided with more than one ultrasonic wave
Transducer；Each ultrasonic transducer is connected through ultrasonic transmission cable with ultrasonic generator.
The ultrasonic wave guide plate is a group or more of, and each group includes two pieces and is clamped in heat exchanger plates through fishbolt is connected
The ultrasonic wave guide plate of piece both sides.
The ultrasonic transducer is piezoelectric-type ultrasonic wave transducer or magnetostriction type ultrasonic transducer.
The ultrasonic wave guide plate is made up of metal material.
The metal material is times in iron, ferroalloy, steel, stainless steel, copper, copper alloy, titanium, titanium alloy, aluminium, aluminium alloy
Meaning is a kind of.
The working frequency of the ultrasonic transducer is 15kHz -35kHz.
The present invention uses continuous on-line operation mode, and plate type heat exchanger is without stop cleaning.
The advantage of the invention is that：Heat exchanger can be kept long-term and run in the state of without dirt cleaning, heat exchanger is improved
Heat exchange efficiency；Using the sterilization algae removal and antisepsis of ultrasonic wave, it can prevent and eliminate heat exchanger to produce underdeposit corrosion and oxidation
Corrosion, so as to ensure heat exchanger safe operation, extends the service life of heat exchanger.The invention belongs to pure physical method, without using
Chemical agent, it is environmentally safe, it is easy for installation using simple, it is substantially non-maintaining；Do not change original equipment normal process flow, it is right
Original equipment not damaged；The continuous online work of ultrasonic scale prevention equipment, without human attendance, heat exchanger is carried out clearly without shutting down
Wash, it is no longer necessary to which substantial amounts of manpower does the clean and maintenance work of heat exchanger, reduces the labor intensity of workman, reduce artificial clear
Wash and using the expense of chemical agent.
Brief description of the drawings
Fig. 1 is structural representation of the invention（Plate type heat exchanger front）.
Fig. 2 is structural representation of the invention（Plate type heat exchanger side）.
Fig. 3 is schematic diagram of the invention.
In figure, 1, supersonic generator, 2, ultrasonic transducer, 3, ultrasonic wave guide plate, 4, fishbolt, 5, ultrasonic wave passes
Transmission cable, 6, service cable, 7, heat exchange plate, 8, rubber sheet gasket, 9, strap, 10, guide rod, 11, column, 12, adapter.
Embodiment
In Fig. 1, Fig. 2, the present invention includes：Ultrasonic generator 1, ultrasonic transducer 2, ultrasonic wave guide plate 3, fishbolt 4,
Ultrasonic transmission cable 5, service cable 6；Described ultrasonic generator 1 passes through ultrasonic transmission cable 5 and ultrasonic wave transducer
Device 2 is connected, and is at least provided with ultrasonic wave guide plate 3 in a ultrasonic transducer 2, ultrasonic wave guide plate 3 and plate type heat exchanger
The side of heat exchange plate 7 be brought into close contact together by fishbolt 4.8 be rubber sheet gasket, and 9 be strap, and 10 be to lead
Bar, 11 be column, and 12 be adapter.
In Fig. 3, service cable 6 incoming transport 220V or 380V, the ultrasonic wave electric energy that supersonic generator 1 is produced after starting
Signal is conducted to ultrasonic transducer 2 by ultrasonic transmission cable 5, and ultrasonic transducer 2 changes ultrasonic wave electric power signal
Into ultra sonic machinery concussion conduction to the ultrasonic wave guide plate 3 being attached thereto, ultrasonic wave guide plate 3 conducts ultrasonic oscillation to therewith
The heat exchange plate 7 being brought into close contact.Ultrasonic oscillation produces high speed eddy effect between the plate face of heat exchange plate 7 and liquid interface,
Dirt attachment can be hindered while clearing up interface to reach the purpose of antiscale；Ultrasonic oscillation acts on heat exchange plate 7 and hard
Micro- punching property shearing effect can be produced during dirty interface, makes hard scale is broken to come off to reach the purpose of scale removal；When ultrasonic oscillation is made
It can make soft dirt is loose to come off during for heat exchange plate 7 with soft dirty interface and liquid interface, while will be changed using the souring of liquid
Dirt removal on hot plate piece 7 is clean.
