The invention relates to an intelligent vacuum degassing system and a control method thereof. The system comprises a main pipe, a water inlet pipe, a filter, a solenoid valve, an atomizing nozzle, a vacuum tank, a gas one-way valve, an automatic exhaust valve, a magnetic flap level meter, a pressure transmitter, a vacuum pump, a temperature sensor, a drain valve, a water pump, a check valve, a water outlet pipe, a PLC cabinet and the like. The system further provides the control method of the system. The control method includes: on and off of the solenoid valve and start and stop of the water pump are controlled according to the water level; the system has the function of judging safety protection pressure; meanwhile, start and stop of the vacuum pump can be controlled according to inner pressure of the vacuum tank. The PLC cabinet is capable of collecting liquid level, temperature and pressure signals; operation of the solenoid valve, operation of the vacuum pump and operation of the water pump are controlled according to the control method and process. The system and the control method thereof have the advantages that dissolved and free gas in water can be removed efficiently, flow resistance of a water system is overcome, energy-saving operation is achieved, and the system and the control method thereof are widely applied to the liquid circulation fields such as heating systems and domestic hot water systems.
Description
technical field [0001] The present invention relates to an intelligent vacuum degassing system and its control method, in particular to a method that can automatically control the electromagnetic degassing system in the vacuum degassing system according to the law that the solubility of air in water changes with pressure and according to specific operating steps and control methods. Valves, water pumps, vacuum pumps and other equipment can be operated to realize automatic degassing. The invention is suitable for water treatment systems such as heating systems and domestic hot water. Background technique [0002] In the heating system, the water contains a large amount of dissolved gas, which will form air resistance and make the hot water circulation not smooth, which will cause the heating users to not heat the heating. Draining water and exhausting air will increase labor costs and operating expenses, and will also increase the energy consumption of water pumps. If the re...
