Description
Technical field
The present invention relates to mud cleaning equipment, a kind of mud Hand scarf system for thermal power plant's cooling tower.
Background technology
The cooling circulating water system of thermal power plant's wet type cooling unit carries the merit diffusing in air by turbine discharge used heat
Can, recirculated water is sucked and delivers to condenser by water circulating pump from cooling tower pond and absorbs waste heat from exhaust, and then recirculated water is sent to
Cooling tower, sub-fraction recirculated water flashes to steam at cooling tower, and moisture discharge enters air and diffuses in air by used heat,
Overwhelming majority recirculated water returns in cooling tower pond, water circulating pump suck and be then sent through condenser cooling turbine discharge.This
In energy transfer process, recirculated water has evaporation loss and fly away loss in cooling tower, for keeping quantity of circulating water constant, need to
Cooling tower ceaselessly supplements fresh water.Fresh water is the middle water from surface water, subsoil water or sewage treatment plant, in recirculated water
Containing substantial amounts of silt, constantly steam from cooling tower into cooling tower pond and moisture content along with the fresh water carrying silt is continuously replenished
Sending out, the silt that fresh water brings constantly is deposited on cooling tower basin bottom, makes cooling tower pond dischargeable capacity diminish, and causes circulation
Water cycle process is obstructed, and recirculated water enters condenser with silt, and silt will be attached on condenser heat exchange surface, at condensing
Device shows that accumulation thickens, and causes condenser heat exchange efficiency to decline.
In order to avoid the influence to sediment condenser heat exchange efficiency in recirculated water with affect cooling tower pond and normally work, lead to
Often, during the maintenance of annual compressor emergency shutdown, it is necessary to the mud in circulating water pool is thoroughly cleared up, condenser is carried out the most clear
Reason.
These cleaning measures have significant limitation, and the effect of cleaning circulation water is the most undesirable.Owing to transporting at unit
Cooling tower pond can not be cleared up between the departure date, it is necessary to just can carry out until major overhaul is shut down.Although cooling tower pond
In mud overhaul shut down during be cleaned, but unit start shooting run duration, when running continuously along with unit
Between accumulation, the thickness of the mud in cooling tower pond will be continuously increased, until shut down desilting, cooling tower pond next time
In ever-increasing mud not only can affect the cooling effectiveness of circulation, more likely jeopardize Turbo-generator Set time serious
Run safety.
Summary of the invention
For solving the problems referred to above, the invention provides a kind of thermal power plant's cooling tower pond mud Hand scarf system, permissible
Cooling tower pond carries out clearing up in thermal power plant's Turbo-generator Set is run the online assignment of mud.Concrete technical scheme is such as
Under:
A kind of thermal power plant's cooling tower pond mud Hand scarf system, including the pond being positioned at bottom cooling tower, also includes
Being positioned at the filtering slurry pond outside cooling tower, one end is goed deep into basin bottom one end and is goed deep into the mud absorption dress on top, filtering slurry pond
Put, the clear water reserviors being connected with filtering slurry pond, the water circle device being connected with cooling tower and pond.
Further, described mud suction means includes connecting according to this desilting mud self-propelled sucker, desilting mud floating pipe,
Mechanical arm, sucker control servomechanism and slush pump, and described desilting mud self-propelled sucker is placed in basin bottom and is adjacent to mud；Described clearly
Mud self-propelled sucker is for sucking mud in clear sludge pipeline；Described mechanical arm controls the finger of servomechanism for receiving sucker
Order, drives the motion of desilting mud self-propelled sucker.
Further, described water circle device includes water circulating pump and the condenser connected according to this, water circulating pump and pond phase
Even, condenser is connected with cooling tower.
Further, described filtering slurry pond includes filter course.
Further, the material of described filter course be sand, flyash or other there is the material of filtration.
The invention has the beneficial effects as follows:
The present invention makes cooling tower pond be always maintained at the state not having siltation, makes circulating water quality more clean, and keeps
Circulation cleans, so that turbine condenser is maintained at preferable heat exchange state, improves the generating of Turbo-generator Set
Efficiency.
Accompanying drawing explanation
Fig. 1 is that present system forms schematic diagram；
Detailed description of the invention
Being described principle and the feature of invention below in conjunction with accompanying drawing, example is served only for explaining the present invention, not
For limiting the scope of the present invention.
As it is shown in figure 1, a kind of thermal power plant's cooling tower pond mud Hand scarf system, including cooling tower 1, it is positioned at cooling tower
The pond 2 of bottom, is positioned at the filtering slurry pond 8 outside cooling tower, and one end is goed deep into basin bottom one end and goed deep on filtering slurry pond
The mud suction means 3 in portion, mud suction means 3 includes desilting mud self-propelled sucker 5, the desilting mud adjustable pipe connected according to this
Road, mechanical arm 3, sucker control servomechanism 4 and slush pump 6, and described desilting mud self-propelled sucker 5 gos deep into basin bottom.Desilting mud
Floating pipe and mechanical arm 3 are combined by retractable and flexible pipeline and telescopic mechanical arm and are forming.Sucker 5 deeply becomes silted up
In mud, under the suction of slush pump 6, being sucked by mud in clear sludge pipeline, under the drive of mechanical arm, sucker can reach
To any part of basin bottom, mechanical arm receives sucker and controls the instruction that servomechanism 4 sends, and drives sucker each in basin bottom
Place's walking, enables sucker to arrive the position of pond silting.
Clear water reserviors 10 are connected with filtering slurry pond and pond 2, and the water purification in clear water reserviors is extracted in pond 2 by water pump 11.Cool
