Description

Technical Field

[0001] This application relates to the field of electrode steam boilers, and in particular to an electrode steam boiler unit. Background Technology

[0002] Currently, high-pressure electrode steam boilers can utilize the differences in three-phase high-voltage electric potential and the conductivity and high impedance of boiler water to generate high-voltage current in the boiler water, directly releasing heat and heating the boiler water, thereby producing steam that can be controlled and utilized.

[0003] Existing conventional electrode steam boiler units include multiple functional modules of electrode steam boiler and auxiliary boiler, which are usually built next to the boiler.

[0004] The existing technical solutions mentioned above have the following drawbacks: In the construction of conventional boiler units, multiple functional modules require cooperation between construction teams for installation, which leads to a complex construction process. Utility Model Content

[0005] This application provides an electrode steam boiler unit to facilitate construction, reduce construction difficulty, and improve the quality of electrode steam boilers.

[0006] The above-mentioned technical objective of this application is achieved through the following technical solution:

[0007] An electrode steam boiler unit includes a horizontally arranged base, a unit frame horizontally arranged on the upper surface of the base along its length, and a boiler body vertically arranged at one end of the unit frame. A water supply tank is suspended above the end of the unit frame away from the boiler body. A water supply pump is arranged below the water supply tank. The water supply pump is connected to the water supply tank and the boiler body through pipes. Multiple functional modules are arranged at the other end of the unit frame. All of the multiple functional modules are supporting modules of the boiler body.

[0008] By adopting the above technical solution, and by setting up a base, unit frame, boiler body and multiple functional modules, this electrode steam boiler unit integrates the steam boiler and the functional modules required by the steam boiler into an independently operable integrated skid-mounted structure through skid-mounted installation. Compared with conventional units where the steam boiler and functional modules need to be installed separately, this electrode steam boiler unit solves the problems of large on-site construction volume and difficulty in ensuring on-site construction quality. This electrode steam boiler unit also solves the problems of conventional units needing to be installed separately and multiple functional modules needing to be transported separately, resulting in high transportation costs. The water supply tank and feedwater pump can replenish water when the liquid level in the boiler body drops, ensuring that the boiler body can continue to work.

[0009] Optionally, the functional module includes a preheater located on the side of the water supply tank near the boiler body, and the pipeline connecting the water pump and the boiler body passes through the preheater.

[0010] By adopting the above technical solution and setting up a preheater, the water in the water supply tank is heated to a specified temperature before entering the boiler body, thereby reducing the amount of heat required to heat the water to the saturation temperature in the boiler body and improving the overall thermal efficiency of the boiler unit.

[0011] Optionally, the boiler body is divided into upper and lower layers. The feed water pump is connected to the lower layer of the boiler body through a pipe. A boiler circulation pump is installed below the water supply tank. The boiler circulation pump is connected to both the upper and lower layers of the boiler body through a pipe. The boiler circulation pump can pump water from the lower layer of the boiler body into the upper layer of the boiler body.

[0012] By adopting the above technical solution and setting up a boiler circulation pump, the boiler circulation pump works during the operation of the boiler body to transport the conductive hot water in the lower layer of the boiler body to the upper layer of the boiler body to react with the electrodes, generate steam, and output it to the outside.

[0013] Optionally, the functional module also includes a cooling water tank located on the side of the makeup water tank near the boiler body, and a cooling water pump located between the boiler circulation pump and the makeup water tank. The cooling water pump is connected to the cooling water tank and the boiler circulation pump in sequence through pipelines.

[0014] By adopting the above technical solution, and by setting up a cooling water tank and a cooling water pump, the cooling water pump draws water from the cooling water tank to liquid cool the shaft seal of the heated boiler circulating pump, thereby reducing the possibility of damage to the boiler circulating pump due to excessive heat and improving the service life of the boiler circulating pump.

[0015] Optionally, a cooling fan is installed on the side of the cooling water tank away from the preheater, and the cooling fan blows cold air into the pipe connecting the boiler circulating pump and the cooling water tank.

[0016] By adopting the above technical solution, and by setting up a cooling fan, the cooling water that has been heated after cooling the shaft seal of the boiler circulating pump is cooled down by the cooling fan and then enters the cooling water tank for reuse, thereby reducing the operating cost of the boiler unit.

[0017] Optionally, the functional module also includes a sampling device installed vertically below the cooling fan, which is connected to the boiler body. A recovery device is installed vertically on the side of the feed water pump near the boiler body, and the recovery device is connected to the water supply tank and the sampling device through pipelines.

[0018] By adopting the above technical solution, and by setting up a sampling device and a recovery device, the sampling device can sample the water in the boiler body at any time, analyze and record the conductivity of the water, which facilitates the subsequent treatment of the water in the boiler body. After the sampling is completed, the hot water is exchanged through the recovery device and then enters the water supply tank, thereby improving the energy utilization rate.

[0019] Optionally, the functional module also includes a dosing device located below the cooling fan, which is connected to the boiler body.

[0020] By adopting the above technical solution, and by setting up a dosing device in conjunction with a sampling device, when the conductivity of the water in the boiler is lower than a set value, the dosing device can automatically add chemicals into the boiler to increase the conductivity and thus improve the working efficiency.

[0021] Optionally, the functional module also includes a control system located inside the unit frame, which is away from the boiler body and below the water supply tank.

[0022] By adopting the above technical solution and setting up a control system that is electrically connected to each functional module, the system collects and analyzes data, thereby ensuring the stable operation of each functional module.

[0023] In summary, this application has the following technical effects:

[0024] 1. By setting up a base, unit frame, boiler body and multiple functional modules, this electrode steam boiler unit integrates the steam boiler and the functional modules required by the steam boiler into an independently operable integrated skid-mounted structure through skid installation. Compared with conventional units where the steam boiler and functional modules need to be installed separately, this electrode steam boiler unit solves the problems of large on-site construction volume and difficulty in ensuring on-site construction quality. This electrode steam boiler unit also solves the problems of conventional units needing to be installed separately and multiple functional modules needing to be transported separately, resulting in high transportation costs.

[0025] 2. By installing a preheater, the water in the water supply tank is heated to a specified temperature before entering the boiler body, reducing the amount of heat required to heat the water to the saturation temperature in the boiler body and improving the overall thermal efficiency of the boiler unit.

[0026] 3. By installing a cooling water tank and a cooling water pump, the cooling water pump draws water from the cooling water tank to liquid cool the shaft seal of the heated boiler circulating pump, reducing the possibility of damage to the boiler circulating pump due to excessive heat and improving the service life of the boiler circulating pump.

[0032] The present application will be further described in detail below with reference to the accompanying drawings.

[0033] This application discloses an electrode steam boiler unit, referring to... Figure 1 The boiler unit includes a horizontally arranged base 1, and a unit frame 2 is arranged on the upper surface of the base 1. The unit frame 2 is composed of multiple square rods welded together. The unit frame 2 is in the shape of a square column, and the length direction of the unit frame 2 is horizontal and parallel to the length direction of the base 1.

[0034] Combination Figures 1 to 4 A vertical boiler body 3 is installed at one end of the length direction inside the unit frame 2. The boiler body 3 is cylindrical and is fixed to the upper surface of the base 1 by support legs that are evenly spaced at equal angles at the lower end. The outer wall of the boiler body 3 is spaced apart from the unit frame 2.

[0035] Combination Figures 1 to 4 The unit frame 2 is equipped with multiple functional modules, including a water supply tank 4 located inside the unit frame 2 away from the boiler body 3. The water supply tank 4 is suspended above the unit frame and its outer wall is fixed to the unit frame 2. The water supply tank 4 is connected to the feed water pump 5 through a pipe. The feed water pump 5 is located below the water supply tank 4 on one side of the unit frame 2 along its length. The feed water pump 5 has two pumps, which are vertically spaced and close to the end face of the unit frame 2 away from the boiler body 3. The feed water pump 5 is connected to the boiler body 3 through a pipe. When the liquid level in the boiler body 3 decreases, the feed water pump 5 pumps water from the water supply tank 4 into the boiler body 3, enabling the boiler body 3 to continue to operate.

[0036] Combination Figures 1 to 4Below the water supply tank 4, there is also a boiler circulation pump 6. The boiler circulation pump 6 is located on the other side of the length direction of the unit frame 2. The length direction of the boiler circulation pump 6 is parallel to the length direction of the unit frame 2. The boiler body 3 is divided into upper and lower layers. The boiler circulation pump 6 is connected to both the upper and lower layers of the boiler body 3. During the operation of the boiler body 3, the boiler circulation pump 6 works to transport the conductive water from the lower layer of the boiler body 3 to the upper layer of the boiler body 3 to react with the electrodes and generate controllable steam.

[0037] Combination Figures 1 to 4 The functional module also includes a preheater 7 vertically installed between the water supply tank 4 and the boiler body 3. The pipeline connecting the water supply pump 5 and the boiler body 3 passes through the preheater 7. The preheater 7 is located inside the unit frame 2 and on the same side as the boiler circulating pump 6. The upper end of the preheater 7 is flush with the upper surface of the water supply tank 4, and the lower end is located below the side of the water supply tank 4. The preheater 7 can preheat the water pumped into the boiler body 3 by the water supply pump 5, thus improving the thermal efficiency of the electrode steam boiler unit.

[0038] Combination Figures 1 to 4 A cooling water tank 8 and a cooling fan 9 are arranged side-by-side near the boiler body 3 in the makeup water tank 4. The cooling water tank 8 is spaced apart from the preheater 7 and the makeup water tank 4. The cooling water tank 8 and the preheater 7 are located on the same side of the unit frame 2 along its length, while the cooling fan 9 is located on the other side of the unit frame 2 along its length. A cooling water pump 10 is installed between the boiler circulating pump 6 and the makeup water tank 4. One end of the cooling water pump 10 is connected to the side of the cooling water tank 8 away from the cooling fan 9 for pumping water. The other end of the cooling water pump 10 is connected to the cooling water tank 8 through the shaft seal of the boiler circulating pump 6 and below the cooling fan 9. During boiler unit operation, the cooling water pump 10 draws water from the cooling water tank 8 to liquid cool the heated shaft seal of the boiler circulating pump 6, reducing the possibility of damage to the boiler circulating pump 6 due to excessive heat. After heat exchange, the water is cooled by the cooling fan 9 and then enters the cooling water tank 8 for reuse. The pipeline supplying water to the boiler body 3 and the pipeline cooling the boiler circulating pump do not interfere with each other.

[0039] Combination Figures 1 to 4 The functional module also includes a sampling device 12 installed vertically below the cooling fan 9 inside the unit frame 2. The sampling device 12 is connected to the boiler body 3 through a pipe. The sampling device 12 can sample the water inside the boiler body 3 at any time and test the conductivity of the sample. When the conductivity is lower than the set value, a chemical dosing device 13 installed below the cooling fan 9 is used to add chemicals into the boiler body 3. The chemical dosing device 13 is located on the side of the sampling device 12 away from the boiler circulation pump 6. Adding chemicals into the boiler body 3 by the chemical dosing device 13 can improve the conductivity of the water inside the boiler body 3.

[0040] Combination Figures 1 to 4The functional module also includes a recovery device 14, which is vertically installed between the water supply pump 5 and the dosing device 13. The lower end of the recovery device 14 is fixed to the upper surface of the base 1. The recovery device 14 is spaced apart from the sampling device 12 and the water supply pump 5. The recovery device 14 is connected to the sampling device 12 and the water supply tank 4 through pipes. The hot water taken out by the sampling device 12 is recycled to the water supply tank 4 after heat exchange through the recovery device 14, thereby improving energy utilization.

[0041] Combination Figures 1 to 4 A control system 11 is vertically installed below the water supply tank 4 on the side of the boiler circulating pump 6 away from the boiler body 3. The surface of the control system 11 away from the boiler circulating pump 6 is flush with the end face of the unit frame 2. The control system 11 is located on the same side as the boiler circulating pump 6. The control system 11 is equipped with a PLC processor, which is electrically connected to each functional module to collect and analyze data. A liquid level sensor is installed in the boiler body 3, which is electrically connected to the PLC processor. When the liquid level in the boiler body 3 is detected to be low, the control system 11 controls the water supply pump 5 to replenish water to the lower layer of the boiler body 3. When the conductivity data of the sample taken by the sampling device 12 is lower than the set value, the control system 11 controls the dosing device 13 to add chemicals to the boiler body 3. According to the set time interval, the control system 11 controls the boiler circulating pump 6 to pump water from the lower layer of the boiler body 3 into the upper layer of the boiler body 3. After the sampling device 12 has completed sampling, the control system 11 controls the recovery device 14 to operate and process the hot water taken by the sampling device 12 through heat exchange and recover it to the water supply tank 4. The control system 11 controls the stable operation of each functional module. Multiple functional modules of the boiler unit are housed within the unit frame 2, enabling the boiler unit to operate independently.
