DETAILED DESCRIPTION

[0033] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0034] like Figure 1 , Figure 2 and Figure 3 , as shown, a water heating device includes a combustion chamber 100, a heat exchange chamber 200, a first condensation chamber 300, a water inlet pipe 400, a heat exchange pipe 500 and a plurality of smoke guide modules 600. The heat exchange chamber 200 is located above the combustion chamber 100, and the first condensation chamber 300 is located above the heat exchange chamber 200. The combustion chamber 100, the heat exchange chamber 200 and the first condensation chamber 300 are three separate independent chamber bodies. A burner 110 is provided in the combustion chamber 100, and the burner 110 is used to burn gas. A plurality of smoke guide modules 600 are vertically and evenly installed in the heat exchange chamber 200, as shown in FIG. Figure 3 and Figure 7As shown, the upper and lower ends of the smoke guide module 600 are openings, and the interior of the smoke guide channel 620 is the smoke guide channel 620. The lower end opening of the smoke guide module 600 is fixed to the bottom of the heat exchange chamber 200 and connected to the combustion chamber 100, and the upper end opening of the smoke guide module 600 is fixed to the top of the heat exchange chamber 200 and connected to the first condensation chamber 300. Figure 5 As shown, the heat exchange tube 500 is in the shape of a coil, spirally installed in the heat exchange chamber 200, and the two ends of the heat exchange tube 500 extend out of the heat exchange chamber 200; wherein the smoke guide module 600 can be arranged to be surrounded between the heat exchange tubes 500. Superconducting liquid is stored in the heat exchange chamber 200, that is, the heat exchange tube 500 and the smoke guide module 600 are immersed in the superconducting liquid. A first condensing tube 310 is arranged in the first condensing chamber 300. The pipeline direction of the water inlet pipe 400 is: the pipeline first enters the combustion chamber 100, and then extends out of the combustion chamber 100 and extends upward to connect with one end of the first condensing tube 310. The other end of the first condensing tube 310 is connected to one end of the heat exchange tube 500, and the other end of the heat exchange tube 500 is the water outlet end extending out of the heat exchange chamber 200. That is, the flow path of water is: water inlet pipe 400, first condensing tube 310, heat exchange tube 500.

[0035] During operation, the burner 110 burns and generates high-temperature flue gas. At the same time, the external cold water is connected to the water inlet pipe 400. The part of the water inlet pipe 400 in the combustion chamber 100 exchanges heat with the flue gas, preheats the water, and then the water rises along the water inlet pipe 400 and enters the first condenser 310. The flue gas rises and disperses in the combustion chamber 100 and enters each smoke guide module 600. It contacts with the superconducting liquid through a sufficient heat exchange area to exchange heat. The superconducting liquid fully absorbs and stores the heat energy in the flue gas, and then the flue gas continues to rise and enters the first condenser chamber 300. The water entering the first condenser tube 310 exchanges heat with the flue gas in the first condenser chamber 300, and finally absorbs and utilizes the remaining heat energy of the flue gas. The water is preheated twice. The flue gas is finally discharged from the first condenser chamber 300 and discharged to the external environment. The water after the second preheating flows along the first condenser tube 310 to the heat exchange tube 500. The water exchanges heat with the superconducting liquid storing heat energy in the heat exchange tube 500. The coil-shaped heat exchange tube 500 greatly increases the flow distance of water in the heat exchange chamber 200, and fully exchanges heat with the superconducting liquid. The water is finally heated or heated to a steam state in the heat exchange tube 500, and then discharged from the tail end of the heat exchange tube 500 for user use.

[0036] The water heating device of the present invention breaks through the structure of traditional water heaters or steam engines, and utilizes the smoke guide module 600 to disperse the high-temperature flue gas generated by the burner 110, thereby increasing the heat exchange area between the flue gas and the superconducting liquid. The superconducting liquid fully absorbs the heat energy in the flue gas, and the water flows in the coil-shaped heat exchange tube 500, which greatly increases the flow distance to fully exchange heat with the superconducting liquid. The overall heat exchange efficiency is extremely high, which effectively improves the utilization rate of thermal energy. When heating an equal amount of water or producing an equal amount of steam, the water heating device only needs to consume a relatively small amount of gas, and can also achieve the effect of energy saving and emission reduction.

[0037] In some specific embodiments of the present invention, the heat exchange tube 500 includes a first pipe 520 spirally formed from bottom to top. Figure 5 and Figure 6 As shown, the first pipe 520 spirals upward from bottom to top, the lower port is connected to the condenser, and the upper port is the water outlet 510. After water enters the first tube body, it spirals upward from bottom to top to be heated.

[0038] Further, such as Figure 6 As shown, the heat exchange tube 500 also includes a second pipe 530 spirally formed from left to right, the second pipe 530 is connected to the first pipe 520, the first pipe 520 surrounds the second pipe 530 or the second pipe 530 surrounds the first pipe 520, that is, the second pipe 530 is also in a coil shape, and is perpendicular to the spiral direction of the first pipe 520. As shown in Figure 6, the first pipe 520 surrounds the second pipe 530. The second pipe 530 spirals from left to right, the upper port of the first pipe 520 is connected to the head end of the second pipe 530, that is, the lower port of the first pipe 520 is connected to the condenser, and the tail end of the second pipe 530 is used as the water outlet 510. The setting of the second pipe 530 further increases the water heat exchange flow distance, and the direction of the first pipe body and the second pipe body cooperates to fully exchange heat with the superconducting liquid. At the same time, the position of the first pipe 520 and the second pipe 530 cooperates to fully utilize the space in the heat exchange chamber 200.

[0039] Further, such as Figure 3 and Figure 4 As shown, the shell of the middle part of the bottom of the heat exchange chamber 200 can be set to be convex upward, so the lower part of the convex shell can simultaneously form the upper part of the combustion chamber 100. In space, the tube body of the second pipe 530 at the bottom is circulated and inserted into the convex shell of the bottom of the combustion chamber 100 during the circling process, and the tube body part located in the combustion chamber 100 exchanges heat with the heat energy in the combustion chamber 100, and the tube body part located in the heat exchange chamber 200 exchanges heat with the superconducting liquid, that is, the second pipe 530 is circulated and inserted between the combustion chamber 100 and the heat exchange chamber 200 for heating, thereby improving the heating effect of water in the second pipe 530 and further improving the utilization rate of thermal energy.

[0040] In some specific embodiments of the present invention, a plurality of liquid guide tubes 710 are provided in the combustion chamber 100, and both ends of the liquid guide tubes 710 are fixed on the chamber wall of the combustion chamber 100 and connected to the interior of the heat exchange chamber 200. Figure 3 and Figure 4 As shown, the shell of the middle part of the bottom of the heat exchange chamber 200 can be set to be convex upward, so that the lower part of the convex shell can simultaneously form the upper part of the combustion chamber 100. The liquid guide tube 710 is located in the upper part of the combustion chamber 100, and the openings at both ends of the liquid guide tube 710 are fixed on the side wall of the convex shell and connected to the inside of the heat exchange chamber 200. The superconducting liquid in the heat exchange chamber 200 can enter the liquid guide tube 710. During the operation, part of the superconducting liquid flows through the liquid guide tube 710 to exchange heat with the high-temperature flue gas in the combustion chamber 100, further improving the utilization rate of thermal energy.

[0041] Furthermore, a plurality of fins (not shown in the figure) are provided on the outer wall of the liquid guiding tube 710, and the fins are utilized to increase the heat exchange area of ​​the liquid guiding tube 710 in the combustion chamber 100, thereby improving the heat exchange efficiency.

[0042] In some specific embodiments of the present invention, Figure 1 and Figure 2 As shown, two burners 110 are arranged in the combustion chamber 100 and are arranged in a left-right distribution. Two first condensing chambers 300 are arranged above the heat exchange chamber 200 and are arranged above the corresponding positions of the two burners 110. A correspondingly connected water inlet pipe 400 is arranged between the burners 110 and the first condensing chamber 300 on the same side, that is, the burners 110 on both sides are respectively provided with a water inlet pipe 400. The two water inlet pipes 400 extend into the combustion chamber 100 and pass through the corresponding burners 110 to preheat the water once, and then pass through the combustion chamber 100 and extend upward, and are respectively connected to the first condensing pipes 310 in the first condensing chamber 300 at the corresponding position for secondary preheating; the first condensing pipes 310 in the two first condensing chambers 300 are respectively led out of the first condensing chamber 300, and then gathered together and flow into the heat exchange tube 500 for heating. The cooperation of the two sets of burners 110 and the two sets of first condensing chambers 300 greatly increases the overall capacity of the equipment.

[0043] Furthermore, a second condensation chamber 800 is provided between the first condensation chamber 300 and the heat exchange chamber 200, a second condensation tube 810 is provided in the second condensation chamber 800, the second condensation tube 810 is connected between the first condensation tube 310 and the heat exchange tube 500, and a plurality of heat exchange fins (not shown in the figure) are provided on the outer wall of the second condensation tube 810. Figure 1 and Figure 2As shown, the second condensation chamber 800 is located above the heat exchange chamber 200, and the first condensation chamber 300 is located above the second condensation chamber 800. After passing through the smoke guide module 600, the flue gas first enters the second condensation chamber 800, and the water flows from the water inlet pipe 400 into the first condensation tube 310 and then enters the second condensation tube 810 and then flows into the heat exchange tube 500. The second condensation tube 810 is used to absorb the residual heat of the flue gas, which is equivalent to preheating the water three times in the combustion chamber 100, the first condensation chamber 300 and the second condensation chamber 800 in sequence before entering the heat exchange tube 500. After the flue gas is discharged from the smoke guide module 600, it passes through the second condensation chamber 800 and the first condensation chamber 300 for secondary cooling, and the heat exchange plate increases the heat exchange area between the second condensation tube 810 and the flue gas, so as to more fully absorb the residual heat in the flue gas.

[0044] In some specific embodiments of the present invention, a fan 720 is provided on the first condensation chamber 300, and the fan 720 exhausts air from the inside of the first condensation chamber 300 to accelerate the discharge of smoke.

[0045] In some specific embodiments of the present invention, the smoke guide module 600 is formed by butting two plate shells 610 together, and a zigzag upward smoke guide channel 620 is formed between the two plate shells 610. Figure 7 and Figure 8 As shown, the two plate shells 610 are provided with winding grooves inside, and after the two plate shells 610 are butted, the grooves inside them are matched to form a smoke guide channel 620. The plate-like structure of the plate shell 610 is used to increase the heat exchange area between the smoke guide module 600 and the superconducting liquid, and the curved smoke guide channel 620 is used to increase the flue gas flow path, so that the flue gas and the superconducting liquid can fully exchange heat.
