Multi-directional nozzle device for radiator fin cleaning machine of indirect air cooling tower in power plant

Abstract

The invention discloses a multi-directional sprayer device of a power plant indirect air cooling tower radiator fin washing machine. The multi-directional sprayer device comprises a fixed water supply pipe, a rotary auxiliary plate, a connecting hose, a driving mechanism and a plurality of movable water supply pipes. One end of the connecting hose is connected with the fixed water supply pipe, the other end of the connecting hose is communicated with the movable water supply pipes, one end of the rotary auxiliary plate is supported on the fixed water supply pipe in a rotary mode, the multiple movable water supply pipes are installed on the rotary auxiliary plate in parallel, the driving mechanism is connected with the movable water supply pipes to conveniently drive the movable water supply pipes to fix the water supply pipes to be a swing center to swing back and forth with an certain angle, each movable water supply pipe is provided with a plurality of nozzles, and a set of sprayers are formed by the nozzles which are located in the same line and formed in the movable water supply pipes. By means of the multi-directional sprayer device, multi-directional simultaneously-rotating strafing spray washing is achieved, the washing area is increased, and the washing efficiency is improved.

Description

technical field [0001] The invention relates to a multi-directional nozzle device of a radiator fin cleaning machine for an indirect air cooling tower of a power plant. Background technique [0002] At present, the cooling system of the steam turbine in the water-saving power plant adopts the hybrid indirect air convection cooling mode, which can reduce the water consumption of the whole plant by more than 60%. It is mainly composed of jet condenser and air cooling tower of Fogo type radiator. The cooling water in the system enters the condenser and directly mixes with the exhaust steam of the steam turbine to condense it; the heated cooling water is pumped to the air cooling tower for heat dissipation. , after being cooled by convective heat exchange with air, it is sent to the jet condenser to enter the next cycle. Its disadvantage is that the heat dissipation fins of the cooling tower are all exposed to the outside world, providing a bed for various pollutants in the air...

AI Technical Summary

Problems solved by technology

Its disadvantages are: the heat dissipation fins of the cooling tower are all exposed to the outside world, providing a bed for various pollutants in the air, and these attachments always affect the effect of cold and heat exchange

The accumulation of more and more serious attachments will cause abnormal operation of the steam turbine, reduce the output efficiency of the steam turbine, and lead to an increase in energy consumption for power generation, thereby increasing production costs

The operating practice of the unit has proved that when the convective airflow is reduced by 20%, the back pressure of the turbine increases by 33%, which affects the safe operation of the equipment and the power generation efficiency

[0003] The nozzles of the existing cleaning machines made in China are a one-way nozzle design mode arranged evenly from top to bottom, and the working scanning angle is 130°, which has the defects of dead angle and long working time
