Abstract:In order to solve the problem that M701F4 gas turbine intake cover filter screen is easy to clog in bad weather (rain, snow, fog, haze) and the time when the willow is more frequent, which leads to the gas turbine output limitation or the unit RB and trip are triggered. Taking Jingru thermal power plant as an example, based on integrated electromechanical control technology and multi-sensor detection technology, the M701F4 gas turbine inlet shell filter washing robot system was designed and developed. The flushing robot system can control the orbit robot through the DCS system to achieve water and air combination cleaning, which can solve the problem of impurity blockage of the filter screen, prolong the service life of the coarse filter element and reduce the labor cost. At the same time, through spray cooling, the inlet air temperature of the compressor is reduced to a certain extent, and the gas turbine output is increased.
