Online ash removal device of intelligent fan rotor

Abstract

The invention discloses an online ash removal device of an intelligent fan rotor. The online ash removal device comprises a liquid source, a compressed gas source, an electrical control system, a gas-liquid control cabinet, a control cable and a gas-liquid composite nozzle; the liquid source and the compressed gas source have certain pressure; the pressure of the compressed gas source is higher than that of the liquid source; a gas inlet and a liquid inlet are formed in the gas-liquid composite nozzle; the liquid source and the compressed gas source communicate with the liquid inlet and the gas inlet of the gas-liquid composite nozzle respectively through pipelines; the electrical control system and the gas-liquid control cabinet are used for controlling the compressed gas source and the liquid source respectively; and the acute angle formed by the axis of the gas inlet of the gas-liquid composite nozzle and the axis of the liquid inlet is theta1. The online ash removal device can realize the effects of preventing the fan rotor from accumulating ash and timely cleaning ash adhering to the surface, online ash removal under the conditions that the fan rotor does not stall and equipment is not shut down can be realized, and the use cycle of the fan rotor is prolonged.

Description

technical field [0001] The invention relates to a dust removal device, in particular to an intelligent fan rotor online dust removal device. Background technique [0002] Dust removal fans, boiler induced draft fans, gas pressurized fans, gas recovery fans and other dust-laden gas conveying fans, after a period of operation, their rotors will be stained with dust, and different parts will be stained at different speeds or have bonded ash blocks Uneven shedding often causes the dynamic balance of the rotor to deteriorate, causing the fan system to vibrate beyond the standard and cannot work normally. In severe cases, the fan and motor will be damaged, and even serious equipment and safety accidents such as rotor flying out, blade breakage and motor burnout will occur. At present, There is no effective solution to prevent the fan rotor from sticking dust and timely online cleaning. The fan rotor is allowed to accumulate dust. After the dynamic balance is damaged, stop the mach...

[0002] Dust removal fans, boiler induced draft fans, gas pressurization fans, gas recovery fans and other dust-laden gas conveying fans, after a period of operation, their rotors will be stained with dust, and different parts are stained at different speeds or have bonded ash blocks Uneven shedding often causes the dynamic balance of the rotor to deteriorate, causing the fan system to vibrate beyond the standard and cannot work normally. In severe cases, the fan and motor will be damaged, and even serious equipment and safety accidents such as rotor flying out, blade breakage and motor burnout will occur. At present, There is no effective solution to prevent the fan rotor from sticking dust and timely online cleaning. The fan rotor is allowed to accumulate dust. After the dynamic balance is damaged, stop the machine for dynamic balancing treatment. Generally, the use time of the fan rotor is short and the processing time is long. ,high cost
