This system is widely used in industrial and commercial heating, hot water supply and other fields. There is no integrated high-voltage electrode hot water boiler system on the market at present. All components are transported to the construction site according to the drawings for assembly. There are many components in the high-voltage electrode hot water boiler system, and it is easy to make mistakes during the assembly construction process, resulting in a long cycle and low construction efficiency. Moreover, for large parts in the high-voltage electrode hot water boiler system, such as high-voltage electrode boilers, etc., fixed foundations need to be pre-cast according to the on-site layout. Once there is an error in the pouring position of the fixed foundation, it will cause the subsequent inability to install according to the installation drawings to form a system, and then transformation is required, increasing the engineering quantity, resulting in problems such as insufficient spare parts and postponed construction period. There is an urgent need for a high-integration high-voltage electrode hot water boiler system at present. Content of the Utility Model

[0020] In Figure 1 、 2 、3, an energy-saving and low-resistance integrated skid-mounted device for an electrode boiler in this embodiment, on one side inside the skid-mounted frame 1, the electrode hot water boiler 2 is fixedly installed, in the middle, an auxiliary component installation box is fixedly installed, and on the other side, the heat exchanger 6 is fixedly installed. Inside the auxiliary component installation box, the pure water tank 24, the dosing device 31, and the pressure stabilizing and expansion device are installed. The water inlet of the electrode hot water boiler 2 is connected to the main water outlet of the heat exchanger 6 through the first pipeline 7, and the water outlet is connected to the water inlet of the heat exchanger 6 through the second pipeline 3. A circulating water pump 4 is connected to the second pipeline 3. The pressure stabilizing and expansion device and the dosing device 31 are successively connected to the first pipeline 7. On the first pipeline 7 between the dosing device 31 and the water inlet of the electrode hot water boiler 2, a local thermometer A30, a local pressure gauge A29, a temperature switch A28, a pressure switch A27, a remote pressure gauge A26, and a remote thermometer A25 are successively installed. On the first pipeline 7 between the pressure stabilizing and expansion device and the water outlet of the heat exchanger 6, a local thermometer C16 and a local pressure gauge C15 are successively installed. A safety valve 8 is connected to the second pipeline 3 near the water outlet of the electrode hot water boiler 2. On the second pipeline 3 between the safety valve 8 and the water inlet of the circulating water pump 4, a local thermometer B9, a local pressure gauge B10, a temperature switch B11, a pressure switch B12, a remote pressure gauge B13, and a remote thermometer B14 are successively installed. Near the water inlet of the heat exchanger 6 on the second pipeline 3, a local thermometer D20 and a local pressure gauge D21 are successively installed. The pure water tank 24 and the make-up water pump 23 are located in the middle inside the skid-mounted frame 1.

[0022] The working principle of the present utility model is as follows:

[0023] When the heating system is started, the electrode hot water boiler 2 begins to heat. The heated water is pumped out of the boiler by the circulation pump 4, and the pump transports the water to the vertical shell-and-tube heat exchanger. Inside the heat exchanger 6, the hot water in the boiler exchanges heat with the cold water in the secondary circuit, transferring the heat to the water in the secondary circuit. On the first pipe 7, a pressure stabilizing and expansion device is installed near the water outlet of the heat exchanger 6 to maintain the stability of the system pressure and prevent system pressure fluctuations caused by temperature changes. The water in the pure water tank 24 is supplemented into the system through the makeup water pump 23 to compensate for the water lost due to evaporation or leakage in the system. The chemical dosing device 31 adds chemical agents to the system to prevent corrosion and scaling. On the second pipe 3, a safety valve 8 is installed near the water outlet of the electrode hot water boiler 2 to prevent the system pressure from being too high. The hot water passing through the heat exchanger 6 returns to the electrode hot water boiler 2 to continue heating, forming a closed-loop cycle. The system is equipped with a variety of sensors and control devices, including in-situ thermometers, in-situ pressure gauges, temperature switches, pressure switches, remote pressure gauges, and remote thermometers, which are used to monitor and adjust parameters such as the temperature and pressure of the system to ensure the safe and efficient operation of the system. The present utility model has a high degree of integration, aiming to reduce the pipe length and complexity, lower the system circulation resistance, and improve the energy utilization efficiency.
