5. The method of producing energy-saving retrofit heating boiler equipment for rubber gloves:


When the boiler is in normal operation, start the boiler to the heating state, open the first oil valve, the second oil valve and the third oil valve; at the same time, start the circulating pump so that the heated oil in the boiler flows to the heating equipment through the first oil pipe. The oil cooled by the thermal equipment flows out from the second oil pipe to the oil and gas separator. Due to the heating of the boiler, part of the gas is generated in the pipe, and the pressure in the pipe increases. When the oil passes through the oil and gas separator, some gas is removed. After the gas is separated, the pressure of the separated gas is greater than the pressure of the expansion tank. The gas continues to be discharged into the liquid chamber of the expansion tank through the third oil pipe. The pressure in the liquid chamber of the expansion tank increases due to the entry of gas, which triggers the overflow valve to expand The excess gas in the tank is discharged to the oil storage tank; the oil separated by the oil and gas separator passes through the fourth oil pipe and then enters the hot oil boiler for heating;


As the entire system continues to operate, the amount of oil in the entire circulation loop will gradually decrease due to the heating part of the gasification, until the pressure in the second oil pipe is less than the pressure of the expansion tank, under the action of the pressure difference, the expansion tank The oil in the oil enters the oil-air separator through the third oil pipe, and is supplemented to the fourth oil pipe with the oil circuit so that the oil volume in the oil circulation pipe reaches the normal level;


As the amount of oil in the expansion tank gradually decreases, start the oil pump on the fifth oil pipe to force the oil in the oil storage tank to flow into the expansion tank, stop the oil filling in time according to the liquid level sensor, and close the fourth oil valve in time.
