Description

Technical Field

[0001] This invention relates to the field of electrode boiler technology, and more particularly to an electrode boiler heating system. Background Technology

[0002] Electrode boilers directly introduce 10kV high-voltage electricity into the water via ABC three-phase electrodes. The water, with its conductivity, acts as a conductor, generating heat without heat exchange, thus minimizing heat loss during conversion. Efficiency can reach over 99%, and a single unit can achieve 70MW or even higher. Skid-mounted boilers transform the boiler from a single heating furnace into a comprehensive heating system, often requiring multiple skids for installation. Since the electrode heating furnace itself has a high-voltage input (6kV / 10kV), various safety protection measures are necessary to mitigate the risk of electric shock. However, mitigation does not eliminate the risk; in current technologies, personnel operating the boiler are relatively close to high-voltage lines and equipment, posing a significant danger. Summary of the Invention

[0003] To address the aforementioned technical problems, this invention discloses an electrode boiler heating system, comprising a skid one, with skid two and skid three disposed on one side of skid one. Skid two is positioned above skid three. An electrode-type hot water boiler is installed inside skid one, high-voltage equipment is installed inside skid two, and low-voltage equipment is installed inside skid three. Through this technical solution, the electrode-type hot water boiler is no longer a standalone heating furnace but a heating system. The use of different skids allows for the installation of different equipment in different locations for easier management. Furthermore, since the electrode heating furnace body has a high-voltage inlet, placing the high-voltage electrical equipment in the same location enhances safety.

[0004] Furthermore, the electrode-type hot water boiler has a vertical structure, with an entrance and exit door on one side of the skid, which is normally locked.

[0005] Furthermore, the first, second, and third pry bars are assembled into a single unit, and an external ladder is installed between the second and third pry bars.

[0006] Furthermore, the bottom of the second skid is equipped with a platform and guardrail, which are connected to an external ladder. This technical solution, constructed by assembling multiple skids, facilitates installation and disassembly. The layered design makes it safer for high-voltage electricity to reach the upper level, and the ladder, platform, and guardrail protect the safety of personnel working on the upper level.

[0007] Furthermore, the second skid includes a high-pressure chamber and a first process chamber, with high-pressure equipment installed in the high-pressure chamber and static equipment installed in the first process chamber.

[0008] Furthermore, the high-voltage room is equipped with a high-voltage distribution cabinet, and the first process room is equipped with a dosing tank, a demineralized water tank, and a water treatment device.

[0009] Furthermore, the water treatment device includes a quartz sand filter, an activated carbon filter, a brine tank, and a water softener. Through the above technical solution, the upper-level high-pressure and static equipment are devices that do not require frequent daily operation. Therefore, the system is designed with locks after entry and exit, requires minimal maintenance, and the skid-mounted distribution ensures safety.

[0010] Furthermore, the skid three includes a second process chamber and a low-pressure chamber, wherein the second process chamber is equipped with a pump assembly and the low-pressure chamber is equipped with a control system.

[0011] Furthermore, the second process chamber is equipped with a boiler circulating pump, a plate heat exchanger, a nitrogen generator, a secondary network circulating pump, and a secondary network makeup water pump.

[0012] Furthermore, the control system includes a power cabinet and a controller. Through the above technical solution, the control system and various pumps are all installed in the lower skid-mounted compartment 3. These devices require frequent maintenance, and placing them on the lower level makes operation more convenient. The advantage of this arrangement is that it physically isolates personnel from the risk of electric shock due to high voltage. This is because the two high-voltage components—the electrode boiler body and the high-voltage chamber—are not operated routinely; routine operations are all conducted within skid-mounted compartment 3. Management can be achieved by padlocks on skids 1 and 2. Furthermore, on-site construction is simple and requires a small footprint.

[0013] The beneficial effects of this invention compared to the prior art are:

[0014] (1) Through the above technical solution, the electrode hot water boiler is no longer a separate heating furnace but a heating system. Setting different skids allows different equipment to be installed in different locations, which is convenient for management. At the same time, the electrode heating furnace body is a high-voltage inlet, so it is safer to put the high-voltage electrical equipment in the same place.

[0015] (2) The above technical solution is assembled by multiple skids, which is convenient for installation and disassembly. The upper and lower layer design makes it safer for high voltage to go to the upper layer. The ladder, platform and guardrail can protect the safety of the workers on the upper layer.

[0016] (3) Through the above technical solution, the high-voltage equipment and static equipment on the upper level are equipment that do not need to be operated frequently on a daily basis. Therefore, the door is locked after entering and exiting, and it does not need to be maintained frequently. The distribution of the skid is reasonable and also ensures safety.

[0017] (4) Through the above technical solution, the control system and various pumps are installed in the lower skid-mounted compartment 3. These devices are all devices with high maintenance frequency. It is more convenient to operate them when they are set up in the lower compartment. The advantage of this arrangement is that it physically isolates the risk of death from high voltage electric shock to personnel. Because the two parts with high voltage are the electrode boiler body and the high voltage chamber, neither of them are operated in daily life. Daily operations are all in the skid-mounted compartment 3. Skid-mounted compartment 1 and skid-mounted compartment 2 can be managed by padlocks. Moreover, the on-site construction is simple and the area occupied is small. Attached Figure Description

Detailed Implementation

[0022] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] like Figs. 1-3The electrode boiler heating system shown includes a skid 1, with skid 2 and skid 3 mounted on one side of skid 1. Skid 2 is positioned above skid 3. An electrode-type hot water boiler 1 is installed inside skid 1, high-voltage equipment is installed inside skid 2, and low-voltage equipment is installed inside skid 3. Through this technical solution, the electrode-type hot water boiler 1 is no longer a standalone heating furnace but a heating system. The different skid mountings allow for the installation of different equipment in different locations for easier management. Furthermore, since the electrode heating furnace body has a high-voltage inlet, placing the high-voltage equipment in the same location enhances safety. The electrode-type hot water boiler 1 employs an inner and outer cylinder structure. The inner and outer cylinders are insulated and fixed, with only low-conductivity demineralized water connecting them. The resistance of this water is much greater than the grounding resistance, ensuring that the voltage of the boiler's outer cylinder remains within a safe range, guaranteeing the boiler's safety even in the event of an electrical protection failure.

[0024] To ensure the safety performance of the high-voltage electrode boiler, the electrode-type hot water boiler 1 consists of inner and outer cylinders. The electrodes are inserted into the liquid surface of the inner cylinder. The inner and outer cylinders must be insulated and separated. The outer cylinder is not the neutral point, ensuring that the neutral point is not grounded when the boiler shell is grounded. This prevents the high-voltage electricity from the electrodes from being directly connected to the outer cylinder through the inner cylinder via a conductor. Furthermore, the outer cylinder of the boiler is grounded at multiple points (protective ground) to ensure that the outer shell is at the same potential as the human body, preventing electric shock. An exhaust pipe 18 and an exhaust silencer 19 are installed on the upper side of the electrode-type hot water boiler 1.

[0025] In this embodiment, the electrode-type hot water boiler 1 has a vertical structure. An entrance / exit 20 is located on one side of skid 1, which is normally locked. Skid 1, skid 2, and skid 3 are assembled into a single unit and fixed with bolts or other means. All skids are enclosed structures. An external ladder is installed between skid 2 and skid 3. Skid 2 has a platform and guardrail at its bottom, which connects to the external ladder. The ladder also has a lock at the lower entrance to prevent people from climbing when not in use. This technical solution, using multiple skids, facilitates installation and disassembly. The layered design makes it safer for high-voltage equipment to reach the upper level, and the ladder, platform, and guardrail protect the safety of personnel working on the upper level. Skid 2 includes a high-voltage chamber 14 and a first process chamber 15. High-voltage equipment is installed in the high-voltage chamber 14, and static equipment is installed in the first process chamber 15. The high-voltage chamber 14 contains a high-voltage distribution cabinet 12, and the first process chamber 15 contains a dosing tank 4, a demineralized water tank 6, and a water treatment device 7. The water treatment unit 7 includes a quartz sand filter, an activated carbon filter, a brine tank, and a water softener. Through the above technical solution, the upper-level high-pressure and static equipment are devices that do not require frequent daily operation. Therefore, the entrance and exit doors are locked after 20 seconds, requiring minimal maintenance. The skid-mounted distribution is reasonable and also ensures safety.

[0026] In this embodiment, skid three includes a second process chamber 16 and a low-pressure chamber 17. The second process chamber 16 houses the pump assembly, and the low-pressure chamber 17 houses the control system 3. The second process chamber 16 houses a boiler circulating pump 2, a plate heat exchanger 8, a nitrogen generator 9, a secondary network circulating pump 10, and a secondary network makeup water pump 11. These components make up the pump assembly. The control system 3 includes a power cabinet and a controller. Through the above technical solution, the control system 3 and the pump assembly are both installed in the lower skid three. These devices are frequently maintained, and placing them in the lower level makes them easier to operate. The advantage of this arrangement is that it physically isolates personnel from the risk of electric shock due to high voltage. Since the two high-voltage components—the electrode boiler body and the high-pressure chamber—are not operated normally, daily operations are all conducted within skid three. Skid one and skid two can be managed with padlocks, and on-site construction is simple, requiring minimal floor space.

[0027] The above embodiments only illustrate one or more implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
