The present invention relates to the cleaning technique field of equipment such as electric power, environmental protection, the energy, colliery, specifically a kind of automatic cleaning device of indirect air cooler for power station that is used for.
Background technology
At present, the air cooling system that is applied in the power plant has: 1. direct air cooling system (ACC); 2. adopt the indirect air cooling system of surface condenser; 3. adopt the indirect air cooling system (being the Hai Le system) of direct-contact type condenser.
Wherein, adopt the indirect air cooling system (being the Hai Le system) of direct-contact type condenser, hybrid indirect air cooling system mainly is to be made of injection type condenser and air cooling tower that good fortune brother type radiator is housed, and the cooling water in the system enters condenser and directly lacks gas with steam turbine and mix and make its condensation.The cooling water overwhelming majority after being heated is delivered to the air cooling tower radiator by circulating pump, delivers to injection type condenser again and enter next circulation after cooling off with the cross-ventilation heat exchange.
The running of indirect air cooling unit constantly is subjected to various external interference, and these extraneous infringements are ubiquitous: pollen, floating dust, insect, flying bird etc. all may become the hidden danger of disturbing its normal operation.These disturbing flows influence heat exchanger effectiveness, have improved operating cost.
The tool related data is introduced: what the cleaning of indirect air cooling unit was adopted in the market is tower outer vertical tube bundle formula cleaning device, shower nozzle is arranged on the aerial cooler periphery, spray angle and cooler cleaning surface angle in moving process change, and do not have vertical cleaning, the cleaning performance extreme difference.
Summary of the invention
The purpose of this invention is to provide the automatic cleaning device of indirect air cooler for power station that is provided with automatic walking and cleaning in a kind of tower near indirect air cooling unit position.
The object of the present invention is achieved like this: it comprises the cleaning tube bank that has walking mechanism, washer jet, it is characterized in that: be set with a closed ring track near on the aerial cooler position of indirect air cooling unit in tower, circular orbit is provided with the walking truss of a band travel driving unit; The walking truss is provided with a vertical frame that moves horizontally along the track vertical direction, also is provided with the guide and limit mechanism of vertical frame on the walking truss; Vertical frame is provided with a vertical moving guide rail, is disposed with vertical walking mechanism, vertical drive mechanism on vertical moving guide rail; On vertical walking mechanism, also be provided with wiper mechanism, this wiper mechanism comprises double at least cleaning tube bank, in the cleaning tube bank, be evenly distributed with washer jet, the injection direction of this washer jet and aerial cooler cleaning surface are perpendicular, clean tube bank and are connected with high pressure water generating device by high-pressure hose.
Travel driving unit of the present invention comprises: transfer or differential travelling mechanism that drive unit that the walking truss moves along circular orbit and walking truss move along circular orbit.
Vertical drive of the present invention mechanism is by drive motors, reductor, shaft joint, synchronizing jugged belt wheel, Castor, brings by profile of tooth to drive vertical walking mechanism walking.
The advantage of automatic flushing device of the present invention:
1, cleaning performance is good: clean perpendicular to the cooler surface formula owing to adopt in the tower, thereby realize optimal cleaning effect.Stepless adjustable operating pressure is easy to set optimum working pressure and flow matches relation, by the fan-shaped cleaning shower nozzle of Specialty Design.
2, automaticity height: Portable Automatic control system, easy to operate, realized that integrated system promptly: orbiting, truss be along perpendicular to the moving horizontally of guide rail, cleaning that wiper mechanism vertically moves, thereby realize chain automatic control, only needs a people can finish whole washing and cleaning operations.
3, environment friendly and pollution-free: adopt clear water as cleansing medium, need not dose any chemical agent, liquid waste processing is simple and convenient.
4, the present invention also have simple and reasonable, overall efficiency height, safety, advantage such as long service life is convenient to safeguard, range of application is wide.
Description of drawings
Fig. 1 is a structural representation sketch of the present invention;
Fig. 2 is that the A of Fig. 1 is to the structural representation sketch; Be that the present invention installs and uses state.
Fig. 3 is that the B of Fig. 2 is to simplified schematic diagram.
The present invention is described in further detail by example below in conjunction with accompanying drawing, but following example only is the present invention's example wherein, the rights protection scope of not representing the present invention and being limited, the scope of the present invention is as the criterion with claims.
The specific embodiment
Example 1
Shown in Fig. 1-3, the closed ring track among Fig. 1 of the present invention, this closed ring track 1 are fixedly installed in the tower near on aerial cooler 13 (as shown in Figure 2) position of indirect air cooling unit; Circular orbit 1 is provided with the walking truss 4 of a band travel driving unit 2, and the described drive unit 2 of walking comprises: the transfer that drive unit that the walking truss moves along circular orbit and walking truss move along circular orbit; Walking truss 4 is provided with a vertical frame 5 that moves horizontally along the track vertical direction, also is provided with the guide and limit mechanism 6 of vertical frame 5 on the walking truss; Vertical frame 5 is provided with a vertical moving guide rail 7, is disposed with vertical walking mechanism 8 (as shown in Figure 3), vertical drive mechanism 3 on vertical moving guide rail 7; On vertical walking mechanism 8, also be provided with wiper mechanism 9, this wiper mechanism comprises up and down double cleaning tube bank 10, in the cleaning tube bank, be evenly distributed with washer jet 12, the injection direction of this washer jet and aerial cooler cleaning surface are perpendicular, clean tube bank and are connected with high pressure water generating device by high-pressure hose.Described vertical drive mechanism 3 is by drive motors, reductor, shaft joint, synchronizing jugged belt wheel, cog belt, by Castor 14 (this vertical drive mechanism and the applicant's application, number of patent application is: " along the horizontal drive mechanism of the guide rail walking " structure in 200920010902.8 is identical) drive vertical walking mechanism 8 operations.
