Embodiment Construction
[0026] The temperature control model includes changing the hot water temperature at the user end according to the heating power.
[0027] The furnace water conductivity model includes feeding monitoring and conductivity measurement, which can detect and regulate conductivity in real time. It can add trisodium phosphate concentrate when the conductivity is increased, and the feeding monitoring includes feeding rate and feeding amount. It can facilitate the control and adjustment of the furnace water concentration.
[0028] S4 also includes performing hydrodynamic analysis on the boiler, and constraining the parameters in the preceding steps. The electrode boiler is modeled and meshed, and the mesh is refined at key positions, including the circulation pump interface, water resistance and pneumatic three-way valve. After multiple sets of grids are established, grid independence verification is performed to determine the final number of grids. The analysis is based on the flow...

The invention discloses an electrode boiler control system and method based on the Internet of Things, and the system is characterized in that the system comprises an electrode boiler, a power controller connected with the electrode boiler, a temperature controller connected with the electrode boiler, and a main control module connected with the power controller and the temperature controller, and the electrode boiler comprises an inner cylinder and a circulating pump; the problem of difficult pressure adjustment is solved, and the stability of system operation pressure is improved. Meanwhile, a power, temperature and other parameter control system is designed to ensure stable operation of the electrode boiler. Wherein the power is quickly and steplessly adjusted by changing the liquid level of the inner cylinder; a semi-immersed electrode hot water boiler structure is adopted, so that the power stepless adjustment range is greatly widened, and the flexibility of the electrode boiler in absorbing a renewable power supply and surplus electric energy is improved.
Description
technical field [0001] The invention relates to the field of electrode boiler control, in particular to an electrode boiler control system and method based on the Internet of Things. Background technique [0002] The application of electrode boilers has a long history in foreign countries. The world's first electrode boiler was born in Europe in 1905. The Swedish Z&I Company invented the submerged electrode boiler, which greatly improves the control accuracy and uses high voltage (6-15kV) for direct power supply, which is called a high-voltage electrode boiler. In the 1990s, jet-type electrode boilers entered China through the Westinghouse Company of the United States. According to the different contact methods between the water flow and the electrode, the high-voltage electrode boiler mainly has the following two structural forms: 1. Submerged electrode boiler: refers to the electrode connected to the high-voltage power supply is directly immersed in the furnace water of t...
