Description

Technical Field

[0001] The utility model relates to the technical field of electrode steam boilers, in particular to an immersed electrode steam boiler. Background Art

[0002] A submerged electrode steam boiler is a type of electrode boiler. Its main feature is that electrodes connected to a high-voltage power supply are directly immersed in the boiler water for heating. Its operating principle is: voltage is applied to the water in the inner drum via three-phase high-voltage electrodes located in the inner drum, causing the water to heat rapidly within a short period of time. A circulating water pump and pipes connect the inner and outer drums. The outer drum is used to store water and replenish water consumed in the inner drum. When the water in the inner drum is displaced due to usage conditions, the solution inside the outer drum is continuously pumped into the inner drum via the circulating water pump to replenish the water consumed. Water in the outer drum is then replenished via an external feedwater pump. Submerged electrode steam boilers offer several advantages over other types of electrode boilers or traditional boilers. For example, they require less circulating water, offer higher steam quality, are relatively simple to operate and maintain, require less equipment, and occupy a smaller footprint, making them suitable for distributed installation.

[0003] After a period of use, the electrodes of existing immersed electrode steam boilers will generate a certain amount of heat. Relying solely on water flow to dissipate heat on the electrodes is insufficient, which can easily lead to performance degradation, deformation, and even damage of the electrode material. Therefore, it is necessary to provide an electrode structure that can improve the heat dissipation effect to ensure the service life of the electrodes. Utility Model Content

[0011] Furthermore, the electrode body is overall conical.

[0012] Furthermore, the side of the heat dissipation fin is opened in a serrated shape.

[0029] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0030] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0031] In order to make the purpose, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0032] See also Figure 1-3 As shown, this embodiment is an immersed electrode steam boiler, comprising:

[0033] The boiler partition assembly includes a boiler body 101, a partition plate 102, a water storage area 103 and an electrode area 104;

[0034] The electrode heat dissipation assembly includes an electrode body 201 and heat dissipation fins 202;

[0035] A partition plate 102 is fixedly installed in the middle of the boiler body 101. The upper end of the partition plate 102 is a water storage area 103, and the lower end of the partition plate 102 is an electrode area 104. An electrode body 201 is provided in the middle of the electrode area 104. Heat dissipation fins 202 are fixedly connected to both sides of the electrode body 201.

[0036] The partition plate 102 is used to separate the upper portion of the boiler body 101 into a water storage area 103 and the lower portion of the boiler body 101 into an electrode area 104. The electrode body 201 provides a guarantee for the generation of current. The provision of the heat dissipation fins 202 can increase the heat dissipation area, thereby improving the heat dissipation efficiency of the electrode body. At the same time, it can absorb scale in the water, reducing the possibility of scale adsorption on the surface of the electrode body 201, and ensuring normal heat dissipation of the electrode body 201.

[0037] There are four electrode bodies 201 in total, and the electrode bodies 201 are evenly spaced.

[0038] The number and position distribution of the electrode bodies 201 can ensure uniform heating of the water flow;

[0039] The electrode body 201 is generally conical;

[0040] The conical opening of the electrode body 201 causes the surface area of ​​the electrode body 201 to gradually increase from the tip to the base. This gradually changing surface makes the current distribution on the electrode body 201 more uniform. The current tends to be dispersed over a larger surface area, thereby reducing the situation where the local current density is too high;

[0041] The side of the heat dissipation fin 202 is opened in a serrated shape;

[0042] The serrated shape can effectively destroy the thermal boundary layer and increase the turbulence of the fluid, thereby improving the heat transfer coefficient and enhancing the heat transfer effect. It can also make the flow of water between the heat dissipation fins 202 more complex and turbulent, thereby increasing the contact and heat exchange between the fluid and the surface of the heat dissipation fins 202.

[0043] The electrode heat dissipation assembly further includes a circular hole 203;

[0044] The heat dissipation fins 202 are provided with circular holes 203 , which are arranged at equal distances.

[0045] The inner surface of the circular hole 203 can also participate in heat exchange, thereby further increasing the effective heat transfer area;

[0046] Also included are electrode monitoring components;

[0047] The electrode monitoring assembly includes a card slot 301 and a sensor 302;

[0048] A slot 301 is provided in the middle of the electrode body 201, and a sensor 302 is fixedly embedded in the slot 301;

[0049] The opening of the card slot 301 provides a guarantee for the installation of the sensor 302. The sensor 302 is connected to an external wireless device and can monitor the temperature, current, voltage and other parameters of the electrode in real time, and feed the data back to the control system so as to adjust the operating status in time and prevent failures.

[0050] Working principle: Water is injected into the electrode area 104 through an external device, and then the electrode body 201 is connected to a power source. At this time, an electric current is generated on the surface of the electrode body 201, causing the boiler water to heat up rapidly in a short period of time. The heated water in the electrode area 104 is then pumped into the water storage area 103. During this process, the heat dissipation fins 202 increase the contact area between the electrode body 201 and the water flow, and the inner surface of the circular hole 203 also increases the contact area with the water flow. When the water flows through the jagged part on the side of the heat dissipation fin 202, the water flow becomes more complex and turbulent. At the same time, the sensor 302 feeds back the temperature, current, voltage and other parameters of the electrode body 201 to the external control system;

[0051] This step can increase the heat dissipation area, thereby improving the heat dissipation efficiency of the electrode body, while ensuring the normal heat dissipation of the electrode body. The serrated opening on the side of the heat dissipation fin can increase the turbulence of the fluid, thereby improving the heat transfer coefficient, and can make the flow of water between the heat dissipation fins more complex and turbulent, increasing the contact and heat exchange between the fluid and the fin surface. At the same time, under the action of the sensor, the temperature, current, voltage and other parameters of the electrode can be monitored in real time, and the data can be fed back to the control system so as to adjust the operating status in time and prevent failures.
