[0008] Through the above technical scheme, the boiler circulating water pump operates to promote the circulation of hot water between the boiler and the heat exchanger, and the external heat supply is realized. The boiler constant pressure water supply pump pumps the pure water in the pure water tank into the electrode boiler to realize the pressurization of the electrode boiler, and then the supply of high-temperature hot water of the boiler system is realized.

[0017] Optionally, a support plate is fixedly arranged at the bottom of the frame, and the electrode boiler is arranged on the support plate.

[0018] By adopting the above technical scheme, the support plate is arranged on the one hand to facilitate the installation of each component and the frame, and on the other hand to improve the structural strength of the frame as a whole.

[0019] Optionally, the dosing device is further arranged, and the dosing device is used for adding electrolyte to the electrode boiler.

[0020] By adopting the above technical scheme, when the conductivity in the electrode boiler decreases, the dosing device can actively add electrolyte to stabilize the balance of the conductivity in the electrode boiler.

[0021] In summary, the present application has at least one of the following beneficial technical effects:

[0022] The plurality of devices are integrated in the rack, which facilitates simplifying the on-site installation steps of the boiler system, shortens the on-site installation time, and improves economic benefits.

The water outlet of the electrode boiler 2 is connected with the water inlet of the plate heat exchanger 4, the outlet of the plate heat exchanger 4 is connected with the water inlet of the boiler circulating water pump 3, and the water outlet of the boiler circulating water pump 3 is connected with the water inlet of the electrode boiler 2. The components are connected through pipelines, and subsequent details will not be described.

[0031] Referring to Figure 1 and Figure 2 , an electric heating device is arranged in the electrode boiler 2, and the water in the electrode boiler 2 is heated by electrifying the electric heating device. The boiler circulating water pump 3 operates to make the hot water circulate between the plate heat exchanger 4 and the electrode boiler 2 to realize continuous heating.

[0032] Referring to Figure 1 and Figure 2, the boiler pressure compensation water pump 6 is communicated with the pure water tank 5 and the electrode boiler 2, when the pressure in the electrode boiler 2 is less than a preset value, the pure water in the pure water tank 5 is pumped into the electrode boiler 2 to realize the pressurization of the electrode boiler 2. The pressure relief valve 7 is also communicated with the electrode boiler 2 and the pure water tank 5, and it can also be understood that the boiler pressure compensation water pump 6 is connected in parallel with the pressure relief valve 7 in the pipeline.

[0033] With reference to Figure 1 and Figure 2 , when the pressure in the electrode boiler 2 is higher than a predetermined value, the pressure relief valve 7 is opened to make the hot water in the electrode boiler 2 be discharged into the electrode boiler 2. The rack 1 is integrally formed as a frame structure with an internal cavity, the electrode boiler 2, the boiler circulating water pump 3, the plate heat exchanger 4, the pure water tank 5, the boiler pressure compensation water pump 6 and the pressure relief valve 7 are all integrated in the internal cavity of the rack 1 and are fixed on the rack 1 by screws. When installed, the installation of the pressure-bearing boiler system can be completed only by fixing the rack 1 in the boiler room. The on-site installation time is shortened, and the economic benefit is improved.

[0034] With reference to Figure 1 and Figure 2 , the rack 1 is divided into two parts in the horizontal direction, the internal space of the rack 1 is defined as a first space and a second space, the electrode boiler 2 is arranged in the first space, and the other components are arranged in the second space.
