Check whether each valve opens and closes reliably and smoothly; if damaged, it should be replaced promptly ； c). Thoroughly inspect vacuum pumps, ventilators, pipeline pumps, various valves, and transmitters, etc ； d). Open the vent valve on the gas-water separation/desiccation/pressure stabilization system ； e). Check whether the packing at both ends of the vacuum pump is in good condition and rotates properly. If it cannot be rotated by hand, try turning it on briefly; if it still doesn’t rotate, turn off the power supply and carefully inspect it according to the vacuum pump’s instructions until it can rotate ； f). Check whether the switches on the pressure transmitters and micromanometers, as well as the butterfly valves in the air-water separation/desiccation/pressure stabilization system, are in the closed position ； g). Check whether there is ice in the vacuum pump and pipeline pump; if ice is present, heat it to melt it first, and only then start the pump once it can operate ； h). Check whether the pressure transmitters (-0.1–0 MPA and 0–10 KPA) are at the 0 position, and whether the oxygen-level transmitter is at 21%; if they are not at the set positions, recalibrate them. i). Whether the filter cloth at the front of the air filter needs to be replaced. 1.1.2 Startup procedures for the oxygen-enriched combustion assistance system: a). For the first use, click on the fan and the vacuum pump separately to check whether their rotation directions are correct; if not, turn off the power supply and adjust the power cables in the control cabinet until the rotation directions are correct. b). Direct the circulating water to the front of the water-ring vacuum pump P301. c). Open the oxygen-enriching generator to the water ring vacuum pump P301 electric butterfly valve (KV1121) ； Open the electric valve (KV1122) at the inlet of the cooling water-fed rotary vacuum pump P301. d). Start fan K102, and after checking that the fan is operating normally ； Start the water ring vacuum pump P301. Once it has started, gradually adjust the opening degree of the water supply valve, while monitoring the ammeter on the control panel and the pressure transmitter on the vacuum pump. Ensure that the current shown on the ammeter is as low as possible and the vacuum level indicated by the transmitter is as high as possible; this represents the optimal opening degree for the water supply valve. Make a mark to use as a reference for future startups (in general, as long as the water pressure remains stable, adjusting the opening degree of the water supply valve will be sufficient). Check whether the transmitter is within the range of -0.065 ¾ to -0.078 MPa, whether the micro-pressure gauge on fan K102 is within the range of 0.85–1.45 KPa, and whether the transmitter on the gas-water separation/desiccation/pressure stabilization system D202 is within the range of 0.5–3.0 KPa. If anything is not within the specified range, the cause should be identified promptly and addressed. e). After startup, inspect on-site to confirm whether the vent electric valve (KV1123) of the water ring vacuum pump P301 is closed ； Check whether KV1121 and KV1122 are in the on state. f). The electric valve (KV1121) at the bottom of the oxygen-enriched liquid separation tank D202 will open and close automatically based on the liquid level. g). Open the butterfly valve on the oxygen-enriched pipeline above the gas-water separation/desiccation/pressure stabilization system, and gradually close the vent valve on that same system, so that the oxygen-enriched gas is delivered through the oxygen-enriched pipeline to the inlet of the combustion air fan in the original incinerator ； 1.1.3 Shutdown procedure for the oxygen-enriched combustion assistance system a) Close the water supply valve for the water ring vacuum pump P301 ； Close electric butterfly valve KV1121 ； Turn off the power to the water ring vacuum pump P301 ； Finally, turn off the power supply to fan K102 ； Close the butterfly valve at the outlet of the circulating water pump to prevent anything from entering the liquid separation tank. b) After shutdown, check on-site whether the vacuum pump P301 vent electric valve opens automatically. c) Open the vent valve at the top and the drain valve at the bottom of the separation tank D202; in winter, it is necessary to drain the water from within the equipment as well as from the circulating water pipes. 1.1.4 Common faults and troubleshooting methods. ? Fault phenomena, fault causes, and elimination methods: The power indicator light does not turn on after the power switch is turned on. 1) Power supply failure; 2) Circuit breaker is disconnected; 3) Wiring issue. The indicator light is damaged. 1) Identify the cause and eliminate the fault; 2) Determine the cause and reset the circuit breaker; 3) Repair or replace it. Fan failure: 1) Fan malfunction, with the thermal relay activating; 2) Fan is overloaded. 1) Identify the cause and eliminate the fault by pressing the reset button on the thermal relay. 2) Identify the cause and adjust the protection settings. Vacuum pump failure: 1) Vacuum pump malfunction, with the motor protection relay activating; 2) Vacuum pump overload. 1) Determine the cause and eliminate the fault. 2) Identify the cause, adjust the load, and adjust the protection settings. Low water pressure: 1) Water shortage; 2) The inlet valve is damaged or has a problem. 1) Identify the cause and restore water supply; 2) Identify the cause and fix the fault. 1.1.5 Maintenance system for the oxygen-enriched combustion assistance system a). The area surrounding the membrane-based oxygen-enriched combustion assistance device should be kept clean to minimize dust contamination, and the ambient temperature must be below 45℃ ； b). Before each use, check whether the filter cotton at the front of the air filter has turned black Under normal circumstances, it should be replaced every 10–15 days (the original design called for an alarm to sound every 240 hours to indicate the need to replace the filter element; the specific replacement interval can be adjusted according to the conditions at the site). Prepare a new filter element, remove the old one, and install the new one in its place. Remove the old one and replace it with a new filter pad for use) ； c). Regularly monitor the water level in the gas-water separation/desiccation/pressure stabilization system; it should remain at normal levels, and water depletion must be prevented ； d). Regularly check whether the temperature rise of the motors in the vacuum pumps and ventilators is within normal limits; if overheating is detected, the cause should be identified immediately and resolved promptly.
