Problems solved by technology
Although the silt in the cooling tower pool was cleaned up during the overhaul shutdown, the thickness of the silt in the cooling tower pool will continue to increase with the accumulation of continuous operation time of the unit during the start-up operation of the unit until the next shutdown Dredging, the ever-increasing silt in the pool of the cooling tower will not only affect the cooling efficiency of the circulating water system, but may even endanger the operation safety of the turbo-generator set in severe cases

The invention discloses an on-line sludge cleaning system for a cooling tower pool in a thermal power plant. The on-line sludge cleaning system comprises a pool (2) located at the bottom of a cooling tower (1), a mud filter tank (8) located outside the cooling tower, a sludge dredging device (3) with one end going deep into the bottom of the pool and the other end going deep into the upper part of the mud filter tank, a clear water pool (10) connected with the mud filter tank, and a water circulating device connected with the cooling tower (1) and the pool (2). The on-line sludge cleaning system can carry out on-line operation of cleaning the sludge on the cooling tower pool in the operation of a steam turbine generator set of the thermal power plant, so that the cooling tower pool is kept in the state of no sludge deposition all the time, the circulating water is clean, the circulating water system is kept clean, a steam turbine condenser is kept in a good heat exchange state, and the power generation efficiency of the steam turbine generator set is improved.
Description
technical field [0001] The invention relates to sludge cleaning equipment, in particular to an online sludge cleaning system for cooling water towers of thermal power plants. Background technique [0002] The cooling circulating water system of the wet-cooling unit in the thermal power plant undertakes the function of dissipating the exhaust steam and waste heat of the steam turbine into the atmosphere. To the cooling tower, a small part of the circulating water evaporates into water vapor in the cooling tower, and the water vapor is discharged into the atmosphere to dissipate the waste heat into the atmosphere. Most of the circulating water returns to the cooling tower pool, sucked by the circulating water pump and then sent to the condenser Cooling turbine exhaust. During this energy transfer process, the circulating water has evaporation loss and drift loss in the cooling tower. In order to keep the circulating water volume constant, it is necessary to continuously reple...
