Description

Technical Field

[0001] This invention relates to the field of electrode boilers, and more specifically, to a water supply device for electrode boilers. Background Technology

[0002] High-voltage electrode boilers directly introduce 6-20 kV high voltage into water, utilizing the water's inherent conductivity to generate heat. This technology eliminates the need for low-voltage transformers, and a single unit can achieve a power output of up to 100 MW. The system is equipped with a thermal storage tank, enabling combined cooling, heating, electricity, and steam supply of various energy grades, significantly improving energy utilization and reducing energy storage costs.

[0003] With the development of society, electrode boilers are now widely used. Since water needs to be added after starting an electrode boiler, the water inlet of the electrode boiler is usually connected to the output pipe to achieve the function of water replenishment. However, conventional water replenishment is low-temperature water source, which can easily reduce the boiler's thermal efficiency after being added to the boiler. Therefore, how to use the high-temperature steam in the filter to preheat the water source is a technical problem to be solved in this field. Therefore, we have made improvements to this and proposed a water replenishment device for electrode boilers. Summary of the Invention

[0004] The purpose of this invention is to provide a water supply device for an electrode boiler, which solves the problem that the large temperature difference between the water supply source and the internal temperature of the filter can easily affect the heating efficiency by being installed in the Agi heating unit.

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solution:

[0006] A water supply device for an electrode boiler includes a pre-water supply treatment system and a first water supply input pipe. The first water supply input pipe is interconnected with a second water supply input pipe of the electrode boiler through a preheating unit. The preheating unit includes a preheating pipe with a water supply preheating cavity at its center. A steam output cavity is provided inside the preheating pipe outside the water supply preheating cavity. The preheating pipe has multiple preheating pipes, which are distributed in a ring at equal intervals.

[0007] One end of each of the multiple water replenishment and preheating cavities is connected to a bent heat exchange tube, and one end of each of the multiple bent heat exchange tubes is connected to the end of the first water replenishment input pipe.

[0008] The other end of each of the multiple water replenishment and preheating cavities is connected to one end of the second water replenishment input pipe via a manifold.

[0009] One end of each of the multiple steam output cavities is connected to a heat collection unit, and the other end of each of the multiple steam output cavities is connected to a steam output diversion unit.

[0010] As a preferred technical solution of this application, the heat collection unit includes a heat collection shroud;

[0011] The heat collection hood includes an inner cavity, and one end of the heat collection hood has a conical cavity. The conical cavity is connected to the interior of the inner cavity through a central channel. The first water supply input pipe extends into the interior of the inner cavity through the central channel and is connected to the bent heat exchange pipe.

[0012] As a preferred technical solution of this application, the heat collection unit further includes a rotating groove, which is located at the other end of the heat collection hood and corresponds to the central channel.

[0013] As a preferred technical solution of this application, the steam output diversion unit includes a steam diversion housing, a rotating shaft is movably provided at the center of the steam diversion housing, and diversion blades are fixed on the surface of the rotating shaft;

[0014] One end of the rotating shaft passes through the steam distribution housing and extends into the inner cavity through a rotating groove. One end of the rotating shaft located in the inner cavity is fixed with a baffle blade, and the other end of the rotating shaft passes through the steam distribution housing to the outside and is connected to a servo motor.

[0015] As a preferred technical solution of this application, the other end of the water replenishment and preheating inner cavity is fixed with a diversion pipe, one end of the multiple diversion pipes is connected to the second water replenishment input pipe, and the servo motor is located between the multiple diversion pipes and is connected and fixed to the second water replenishment input pipe.

[0016] As a preferred technical solution of this application, the multiple annularly distributed preheating pipes surround an assembly space, and the heat collection shroud is embedded inside the assembly space.

[0017] As a preferred technical solution of this application, a connecting pipe is also fixed on the heat collection cover at the position of the conical cavity, one end of the connecting pipe is inserted into the inner cavity, and the other end of the connecting pipe is connected to one end of the steam output inner cavity.

[0018] As a preferred technical solution of this application, the pre-treatment water replenishment system includes a raw water tank, a soft water treatment tank, a deoxygenation tank, a buffer storage tank, and a water replenishment tank. The raw water tank, the soft water treatment tank, the deoxygenation tank, the buffer storage tank, and the water replenishment tank are connected in sequence through pipelines, and the water replenishment tank is connected to the first water replenishment input pipeline through a water replenishment pump.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] In the scheme of this application:

[0021] 1. By setting up a preheating unit, the high-temperature steam inside the electrode boiler can be input into the steam distribution shell and dispersed into different preheating pipes through multiple guide pipes during operation. In this way, while the high-temperature steam flows in the steam output cavity, it can exchange heat with the water to be input in the water replenishment preheating cavity. The high temperature of the high-temperature steam itself can preheat the water that needs to be replenished, thereby effectively reducing the temperature difference after input into the filter, which is conducive to better heating of the boiler and improvement of thermal efficiency.

[0022] 2. Through the coordination of the set heat collection units, the high-temperature steam travels in the preheating pipe to heat the water source, and then the steam is output in the steam output cavity. In this way, it can be finally output into the heat collection hood. Since the added water source will be input into the preheating pipe through the bent heat exchange pipe, the preheating of the water source that will be input into the preheating pipe can be further improved, thereby improving the overall heat exchange efficiency and the energy utilization rate of high-temperature steam.

[0023] 3. Through the combination of the rotating shaft, the flow-diverting blades and the turbulence-dispersing blades, the steam can be simultaneously dispersed in multiple directions during output, thereby promoting better heat exchange in multiple preheating pipes. At the same time, the airflow can be disturbed within the heat collection hood, allowing the bent hot rubber ring pipe to be better preheated in the inner cavity. Attached Figure Description

[0045] Please see Figures 1 to 7 This invention provides a technical solution: a water supply device for an electrode boiler, comprising a pre-water supply treatment system 1 and a first water supply input pipe 11. The first water supply input pipe 11 is interconnected with a second water supply input pipe 12 of the electrode boiler via a preheating unit 2. The preheating unit 2 includes a preheating pipe 21, with a water supply preheating cavity 22 formed at the center of the preheating pipe 21. A steam output cavity 23 is provided inside the preheating pipe 21 outside the water supply preheating cavity 22. Multiple preheating pipes 21 are arranged in a ring with equal spacing, such as... Figure 1 As shown, multiple preheating pipes 21 are arranged in a ring, so the preheating treatment of multiple preheating pipes 21 can be achieved simultaneously, making it more practical.

[0046] One end of each of the multiple water replenishment and preheating cavities 22 is connected to a bent heat exchange pipe 25, and one end of each of the multiple bent heat exchange pipes 25 is connected to the end of the first water replenishment input pipe 11.

[0047] One end of each of the multiple steam output cavities 23 is connected to a heat collection unit 3, and the other end of each of the multiple steam output cavities 23 is connected to a steam output diversion unit 4.

[0048] The heat collection unit 3 includes a heat collection cover 31;

[0049] The heat collection hood 31 includes an inner cavity 310. One end of the heat collection hood 31 has a conical cavity 311. The conical cavity 311 is connected to the interior of the inner cavity 310 through a central channel 312. The first water supply pipe 11 extends into the interior of the inner cavity 310 through the central channel 312 and is connected to the bent heat exchange pipe 25.

[0050] The heat collection unit 3 also includes a rotating groove 32, which is located at the other end of the heat collection cover 31 and corresponds to the central channel 312.

[0051] The steam output diversion unit 4 includes a steam diversion housing 41, and a rotating shaft 42 is movably provided at the center inside the steam diversion housing 41. Diversion blades 43 are fixed on the surface of the rotating shaft 42.

[0052] One end of the rotating shaft 42 passes through the steam diversion housing 41 and extends into the inner cavity 310 through the rotating groove 32. One end of the rotating shaft 42 located in the inner cavity 310 is fixed with a baffle 45, and the other end of the rotating shaft 42 passes through the steam diversion housing 41 to the outside and is connected to a servo motor 44.

[0053] As high-temperature steam flows into the steam distribution shell 41 through the pressure relief pipe in the electrode boiler and towards the preheating pipe 21, the flowing steam drives the distribution blades 43 to rotate, which in turn drives the rotating shaft 42 to rotate. The rotating shaft 42 then drives the turbulence-inducing blades 45 on it to rotate. Since the turbulence-inducing blades 45 are located inside the heat collection shroud 31, when steam is input into the heat collection shroud 31, the turbulence-inducing blades 45 can turbulentize the steam, thereby promoting the contact between the steam and the bent hot rubber ring pipe 25, and achieving a better preheating effect. It should be noted that when the flow rate of high-temperature steam is insufficient, the servo motor 44 can be activated to drive the rotating shaft 42 to perform active distribution and turbulence effects.

[0054] The surface of the steam diversion housing 41 is connected to the corresponding steam output cavity 23 via a guide pipe 46;

[0055] The other end of each of the water replenishment and preheating inner cavity 22 is fixed with a diversion pipe 220. One end of each of the multiple diversion pipes 220 is connected to the second water replenishment input pipe 12. The servo motor 44 is located between the multiple diversion pipes 220 and is connected and fixed to the second water replenishment input pipe 12.

[0056] Multiple annularly distributed preheating pipes 21 surround and form an assembly space 210, and the heat collection shroud 31 is embedded inside the assembly space 210.

[0057] A connecting pipe 33 is also fixed on the heat collection hood 31 at the position of the conical cavity 311. One end of the connecting pipe 33 is inserted into the inner cavity 310, and the other end of the connecting pipe 33 is connected to one end of the steam output inner cavity 23.

[0058] The pre-treatment water replenishment system 1 includes a raw water tank 13, a soft water treatment tank 14, a deoxygenation tank 15, a buffer storage tank, and a water replenishment tank. The raw water tank 13, the soft water treatment tank 14, the deoxygenation tank 15, the buffer storage tank, and the water replenishment tank are connected in sequence through pipes. The water replenishment tank 17 is connected to the first water replenishment input pipe 11 through a water replenishment pump 18.

[0059] In practical applications, one end of the second water supply input pipe 12 is connected to the water supply pipe of the electrode boiler, and then one end of the steam diversion shell 41 is connected to the surface of the steam discharge pipe on the electric boiler.

[0060] When the electrode boiler is used for heating, the high-temperature steam inside is input into the steam distribution shell 41 through the pressure relief pipe. The steam is then simultaneously input into the steam output cavity 23 inside the preheating pipe 2 through multiple guide pipes 46. At this time, the water treated in the pre-water treatment system 1 is input into the bent heat exchange loop pipe 25 through the first water input pipe 11, and finally into the water preheating cavity 22 inside the preheating pipe 21. At this time, the high-temperature steam will exchange heat with the water, thereby heating the water, reducing the temperature difference with the water inside the boiler, and ensuring the stability of heating efficiency.

[0061] The water heated inside the preheating pipe 21 will be fed into the second water supply pipe 12 through the diversion pipe 220 and finally into the electrode boiler to achieve the water supply effect.

[0062] During the heat exchange process of the water body described above, although the temperature of the steam output from the preheating pipe 21 is reduced to a certain extent after heat exchange, it still has a temperature difference at one end relative to the water body used for replenishment. Therefore, it will eventually be output into the interior of the heat collection shroud 31. In the process of the water source in the first replenishment water input pipe 11 being input into the preheating pipe 21, it will pass through the bent heat exchange pipe 25. Since the bent heat exchange pipe 25 is located inside the heat collection shroud 31, the steam located there can preheat the water source that is about to be input into the preheating pipe 21, thereby improving the overall preheating effect of the device.

[0063] The above embodiments are only used to illustrate the present invention and are not intended to limit the technical solutions described herein. Although the present invention has been described in detail with reference to the above embodiments, the present invention is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present invention, as well as all technical solutions and improvements that do not depart from the spirit and scope of the invention, are covered within the scope of the claims of the present invention.
