Description
Technical field
The present invention relates to condenser cleaning technique field, be specifically related to a kind of thermal power plant that is applicable to based on the condenser cleaning equipment of injection effect and method.
Background technology
Condenser is the cold junction of power plant's thermodynamic cycle, and its Main Function is that turbine discharge is condensed into water, is formed and keeps higher vacuum.Heat exchange tube of condenser encrustation can be divided three classes by formation mechanism: incrustation scale, dirt, biological sludge in industrial.Incrustation scale is because recirculated water constantly evaporates, make the calcium in water, magnesium concentrate deposition formed, its main component is calcium carbonate, belongs to hard scale, should not remove; Dirt is that the deposition such as impurity, dust, silt particle, micropopulation owing to comprising in recirculated water is formed, more loose; Biological sludge in industrial is the growth and breeding due to algae in water and mushroom, is attached to one deck biomembrane that tube wall is formed, softer.
After heat exchange tube of condenser fouling, heat transfer effect can be caused to reduce, soften(ing), thermal efficiency of cycle reduces, and gross coal consumption rate increases, and the economy of unit reduces; Cause the corrosion of heat exchanger tube, reduce condenser service life, leak time serious, to the safe operation generation significant impact of Steam-water Quality and unit.Therefore, clean heat exchange tube of condenser in time, make it keep clean very important.
At present, the cleaning method of condenser mainly contains: 1) rubber ball cleaning, the cleaning method of comparatively extensive use at present.It can be implemented in line cleaning, and cleaning performance is better, handling safety, but glueballs easily blocking in pipe, and the rate of recovery is low, costly.2) Chemical cleaning.Its cleaning is comparatively thorough, can on-line cleaning, but technique is loaded down with trivial details, and chemical feeding quantity is difficult to accurate control, may cause equipment corrosion, spends larger.3) artificial steel brush cleaning.The method can reach cleaning object, but can only clean by off-line, wastes time and energy.4) high-pressure water jet condenser on-line cleaning Robotics.This technology maintains the features such as the cleaning of off-line Cleaning by High Pressure Water Jet is thorough and harmless to condenser, pollution-free, can realize again On Line Foul Removing Technology, avoids to open, shut down the economic loss brought, and has good prospect.What this technology adopted at present is that water under high pressure drives the shower nozzle connecting high-pressure water hose, put in condenser tube and clean, but in engineering reality, encounter some problems, as: shower nozzle stretches into cleaning in condenser tube needs very large thrust, so may occur in reality that thrust causes shower nozzle not stretch into completely not, cause cleaning not exclusively; Shower nozzle and high-pressure water hose may be stuck in heat exchanger tube; The underwater reliability of coil device of high-pressure water hose is not strong; Arrange that coil system possible space is not enough under water.
Summary of the invention
Technical problem: the present invention seeks to the weak point overcome in prior art, provides a kind of structure is simple, easy to operate, reliability is strong, scaling effect the is good condenser cleaning equipment based on injection effect and method.
Technical scheme: the condenser cleaning equipment based on injection effect of the present invention, it is contained in through shower nozzle fixed seating the induction apparatus that robot cleans on shower nozzle, the other end is positioned on heat exchange tube of condenser entrance by one end and forms, and described induction apparatus is made up of suction casing, contraction section, throat's mixing section, outlet diffuser and exit seal section successively; The tapered body of described contraction section, big opening end is connected with suction casing, and osculum end is connected with throat mixing section, the described tapered body of outlet diffuser, and osculum end is connected with throat mixing section, and big opening end is connected with exit seal section.
The horizontal sextant angle of described contraction section is 30 °, and length is 10-13mm; The diameter of throat's mixing section is 13mm-17mm, and length is 52-68mm; The horizontal sextant angle of outlet diffuser is 3 ~ 5 °, and length is 45-80mm.
Use the condenser cleaning method based on injection effect of described device, comprise the steps:
A. the suction casing of induction apparatus is contained on robot cleaning shower nozzle through shower nozzle fixed seating, the exit seal section of induction apparatus is positioned on the heat exchange tube of condenser entrance of needs cleaning, and compresses;
B. high-pressure hydraulic pump is opened, inject at a high speed the contraction section of induction apparatus through the suction casing of induction apparatus after water under high pressure cleans shower nozzle acceleration decompression by robot, and low pressure is caused near the outlet of robot cleaning shower nozzle, because the pressure of water in the underwater environment at place when cleaning device works is greater than the pressure of the high-velocity flow near cleaning spray outlet, the water thus around cleaning device is entered by the porch of aspirating in a large number from suction casing; Import in throat's mixing section together with the high-velocity flow that robot cleans shower nozzle and through contraction section and mix gradually, then outlet diffuser is entered, enter heat exchange tube of condenser finally by exit seal section, by washing away of current, the dirt of heat exchange tube of condenser inwall is removed.
Beneficial effect: owing to adopting technique scheme, the soft dirt of representative that what the present invention enough effectively removed heat exchange tube of condenser with algae is, efficiently solves some problems that current high-pressure water jet condenser on-line cleaning robot runs in engineering reality.Compared with prior art, tool has the following advantages:
1) can carry out on-line cleaning, during cleaning, generating set need not be shut down, and saves the maintenance cost in power plant.
2) after adopting this device, the stream scooter 7m/s of water in heat exchanger tube, this speed has good cleaning performance to the soft dirt taking algae as representative; And if the water under high pressure of uniform pressure is directly sprayed into heat exchange tube of condenser, then axial velocity decays rapidly, and after 0.1m, speed is almost 0, and heat exchanger tube total length is 10m, and the 9.9m that is can not get effective washing.Therefore adopt this device greatly can improve the flow velocity of water in heat exchange tube of condenser, and then improve its cleaning performance, thus ensure the work normally and efficiently of condenser, ensure the economy of unit operation.
3) pollution-free, handling safety, can not cause damage to tube wall.
4) method is simple, and cost is lower.
