Its basic production process is: when the fuel is burned, it heats water to generate steam, the steam pressure drives the turbine to rotate, the heat energy is converted into mechanical energy, and the mechanical energy is converted into electrical energy. When the thermal power plant needs to remove dust, it uses a dust removal device. At present, most dust removal devices are prone to accumulate a lot of dust inside. At the same time, due to the small internal space of the dust removal device, the user is unable to clean the equipment stably, which easily causes the air inlet of the dust removal device to be blocked, which is not conducive to the normal use of the dust removal device. At present, most of them use manual cleaning operations, which are not timely and inefficient.
