Because the fly ash system conveying wind and the warehouse pump pressure wind are provided by the same pipeline, the warehouse pump pressure is insufficient during operation, the ash loading is small, the time is long, and the ash discharge is not smooth, and the ash discharge rate is too slow, resulting in the electrostatic precipitator. hopper fouling too high, affecting the normal operation of the electrostatic precipitator. After monitoring and analyzing the process circuit and control equipment of the on-site ash discharge system, the method of changing the opening degree of the branch ash conveying line to control the manual valve is adopted, the branch head of the pressurizing circuit is increased, and the working chamber pump is improved. The discharge pressure, combined with the actual branch ash conveying head in the system control logic, changes the ashing logic parameters of each branch and improves the system operation effectiveness. During the commissioning of fly ash discharge, it was found that the ash storage system air compressor was not enough when the ash storage system was put into operation. When the control logic found that the outlet pressure was low, it would be considered that the operation of the air compressor was disabled and the spare air compressor was activated. At the same time, the air compressor is cut off, causing the logic stop of the air compressor to cause the ash storage area to lose the source of compressed air, which brings great accidents to the system operation. Therefore, from the hardware and software aspects, the system has been improved. In the software, the control mode of the air compressor for the ash storage system is changed. When the operating and standby air compressors are in normal condition, the operation mode of the air compressor does not change. When the standby air compressor is in the fault offline situation At the same time, the system only monitors the air compressor outlet pressure and issues a corresponding alarm. At the same time, the air compressor will continue to work without stopping, ensuring that at least one air compressor can run continuously to provide continuous compressed air volume. On the hardware system, an auxiliary air source is introduced from the gas pipeline of the whole plant. Through the improvement of these two aspects, the pressure and gas consumption of the instrument gas in the working area of ​​the ash warehouse are ensured, and the safety and normal operation of the ash storage system are ensured.
