Description

Technical Field

[0001] This utility model relates to the field of steam equipment technology, specifically to a superconducting heat-saving fuel steam generator. Background Technology

[0002] Traditional fire-tube steam generators are fuel-fired steam generators. Due to their relatively small furnace design and short flue tube length, these generators have very low heat conversion rates. Furthermore, in fire-tube steam generators, the flue gas travels a short distance within the furnace, resulting in high exhaust temperatures (230°C to 280°C). This leads to some waste of fuel-fired thermal energy, and the high temperatures can cause pollution from harmful substances entering the gas system.

[0003] Publication No. CN211551560U discloses a stable oil-fired or coal-fired steam generator, including a housing, a control box embedded in the front of the housing, a cover fixedly installed on the right side of the control box on the front of the housing, an evaporation chamber fixedly installed on the top of the inner wall of the housing on the back of the cover, and a fuel chamber fixedly installed at the bottom of the evaporation chamber inside the housing.

[0004] To address the issue of excessive internal pressure causing damage and reduced lifespan when steam generation exceeds steam output, existing technology involves installing buffer tanks at the top of the two connecting pipes, with safety valves connected to the top of the buffer tanks. However, this approach still results in low heat conversion efficiency and consequently higher operating costs. Utility Model Content

[0007] A superconducting thermal energy-saving fuel steam generator includes a heating mechanism, a preheating and cooling mechanism fixedly connected to the top of the heating mechanism, and a control cabinet fixedly connected to one side of the heating mechanism.

[0008] The heating mechanism includes a water tank, an isolation plate is fixedly connected to the inner wall of the water tank, a first smoke chamber is fixedly connected to the top of the isolation plate, a first smoke pipe is fixedly connected to the bottom of the first smoke chamber, a second smoke chamber is fixedly connected to the bottom of the first smoke pipe, a second smoke pipe is fixedly connected to the top of the second smoke chamber, and a third smoke chamber is fixedly connected to the top of the second smoke pipe.

[0009] A further improvement of the present invention is that: the flue includes an outer wall, the top of the outer wall is fixedly connected to the flue chamber, a steel-copper composite spiral heat-conducting sheet is fixedly connected to the inner wall of the outer wall, and ventilation holes are provided on the side wall of the steel-copper composite spiral heat-conducting sheet.

[0010] A further improvement of the present invention is that: the second smoke-converting chamber includes an outer wall of the second smoke-converting chamber, the top of the outer wall of the second smoke-converting chamber is fixedly connected to the first smoke pipe, the top of the outer wall of the second smoke-converting chamber is provided with a pipe hole, the inner wall of the pipe hole is fixedly connected to the first smoke pipe, and a steel-copper composite heat-conducting sheet is fixedly connected to the inner wall of the outer wall of the second smoke-converting chamber.

[0011] A further improvement of this utility model is that: a heating furnace is fixedly connected to the bottom of the water tank, a burner is fixedly connected to one side of the heating furnace, and movable wheels are fixedly connected to the bottom of the heating furnace.

[0012] A further improvement of this utility model is that: an exhaust pipe is fixedly connected to one side of the water tank, and a water valve is rotatably connected to the outer wall of the exhaust pipe.

[0013] A further improvement of the present invention is that the preheating and cooling mechanism includes a preheating box, the bottom of which is fixedly connected to a water tank, a vent hole is provided at the bottom of the preheating box, a water injection pipe is fixedly connected to the inner wall of the preheating box, a heat-conducting wire is fixedly connected to the outer wall of the water injection pipe, a smoke outlet pipe is fixedly connected to the top of the preheating box, and a ventilation mechanism is fixedly connected to the top of the smoke outlet pipe.

[0014] A further improvement of the present invention is that the ventilation mechanism includes a fixed ring, the bottom of which is fixedly connected to the smoke outlet pipe, a fixed pipe is fixedly connected to the inner wall of the fixed ring, a motor is fixedly connected to the inner wall of the fixed pipe, and a ventilation fan is fixedly connected to the output end of the motor.

[0015] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0016] 1. This utility model provides a superconducting heat-saving fuel-fired steam generator, which consists of a water tank, a heating furnace, a burner, casters, an isolation plate, a first flue gas chamber, a second flue gas chamber, a third flue gas chamber, an exhaust pipe, a water valve, and steel-copper composite spiral heat-conducting plates. In use, the operator first moves the device to the desired location using the casters at the bottom of the heating furnace. External purified water is then supplied to the water tank via the water injection pipe. Simultaneously, external fuel is connected to the burner, supplying fuel to the heating furnace. The burner is then activated via the control cabinet to heat the isolation plate at the bottom of the water tank, generating high-temperature flue gas that enters the flue gas chamber. Inside chamber one, the heat-receiving area of ​​the flue gas transfer chamber is increased by steel-copper composite heat-conducting plates to absorb more heat energy. The superconductivity of the heat-conducting plates heats the outer wall of the flue gas transfer chamber. Heat exchange occurs between the outer wall of the flue gas transfer chamber and the water source. Then, the flue gas enters the interior of flue pipe one through the pipe inlet. The outer wall of the flue pipe is heated by steel-copper composite spiral heat-conducting plates. At the same time, the flow rate and trajectory of the flue gas are disturbed by the ventilation holes, causing the flue gas to fully scour the outer wall of the flue pipe and increase the temperature of the flue pipe. Subsequently, the flue gas passes through flue pipe two and flue gas transfer chamber three in sequence, which also increases the flow length of the flue gas. The operator rotates and opens the water valve to allow the steam generated by the device to be discharged through the exhaust pipe, increasing the heat absorption effect and thus achieving a better heat conversion effect.

[0017] 2. This utility model provides a superconducting heat-saving fuel steam generator. Through the cooperation of a preheating box, a vent, a water injection pipe, a heat-conducting wire, and a flue gas outlet pipe, the flue gas enters the preheating box through the vent and exchanges heat with the heat-conducting wire. The heat-conducting wire transfers heat to the outer wall of the water injection pipe, and exchanges heat with the external water source through the water injection pipe, preheating the external water source. At the same time, it absorbs the heat of the flue gas, cools the flue gas, and discharges it through the flue gas outlet pipe. This reduces the flue gas outlet temperature of the equipment and preheats the water in the water injection pipe, thereby improving the thermal energy utilization rate.

[0018] 3. This utility model provides a superconducting heat-saving fuel steam generator. Through the cooperation of a fixed ring, a fixed pipe, a motor, and a ventilation fan, the operator turns on the motor through the control cabinet. The motor drives the ventilation fan to rotate. The rotation of the ventilation fan generates airflow, which draws the flue gas inside the device through the fixed pipe and discharges it. At the same time, external oxygen enters the device through the fixed pipe to supply oxygen to the interior of the heating furnace and increase the stability of the device.

The inner wall of the chamber is fixedly connected with a steel-copper composite spiral heat-conducting plate 172. The side wall of the steel-copper composite spiral heat-conducting plate 172 is provided with a ventilation hole 173. The second flue gas chamber 18 includes an outer wall 181 of the flue gas chamber. The top of the outer wall 181 of the flue gas chamber is fixedly connected with the flue pipe 17.

[0029] In this embodiment, during use, the operator first moves the device to the desired location using the casters 14 at the bottom of the heated furnace 12. External purified water is then supplied to the water tank 11 via the water inlet pipe 23. Simultaneously, external fuel is connected to the burner 13, supplying fuel into the heated furnace 12. The operator then operates the control cabinet 3 to turn on the burner 13, which in turn heats the isolation plate 15 at the bottom of the water tank 11, generating high-temperature flue gas that enters the flue gas transfer chamber 16. The steel-copper composite heat-conducting sheet 183 increases the heating area of ​​the flue gas transfer chamber 16, absorbing more heat energy. The superconducting thermal conductivity... The outer wall 181 of the flue gas exchange chamber is heated, and heat exchange occurs between the outer wall 181 and the water source. Then, the flue gas enters the flue pipe 17 through the pipe hole 182. The outer wall 171 of the flue pipe is heated by the steel-copper composite spiral heat-conducting plate 172. At the same time, the flow rate and trajectory of the flue gas are disturbed by the ventilation hole 173, which causes the flue gas to fully flush the outer wall 171 of the flue pipe and increase the temperature of the flue pipe. Then, the flue gas passes through the second flue pipe 19 and the third flue gas exchange chamber 110 in sequence, which also increases the flow length of the flue gas.

[0032] In this embodiment, the flue gas enters the preheating box 21 through the vent 22 and exchanges heat with the heat-conducting wire 24. The heat-conducting wire 24 transfers heat to the outer wall of the water injection pipe 23 and exchanges heat with the external water source through the water injection pipe 23 to preheat the external water source.

[0035] In this embodiment, the operator operates the control cabinet 3 to turn on the motor 263, which drives the ventilation fan 264 to rotate. The rotation of the ventilation fan 264 generates airflow, which draws the flue gas inside the device through the fixed pipe 262 and discharges it. At the same time, external oxygen enters the device through the fixed pipe 262 to supply oxygen to the interior of the heating furnace 12.

[0036] The working principle of this superconducting thermal energy-saving fuel steam generator will be explained in detail below.

[0037] like Figure 1-6As shown, during use, the operator first moves the device to the desired location using the casters 14 at the bottom of the heated furnace 12. External purified water is then supplied to the water tank 11 via the water inlet pipe 23. Simultaneously, external fuel is connected to the burner 13, supplying fuel into the heated furnace 12.

The steel-copper composite heat-conducting plates 183 increase the heating area of ​​the flue gas transfer chamber 16, absorbing more heat energy. The superconducting properties of the heat-conducting plates heat the outer wall 181 of the flue gas transfer chamber. Heat exchange occurs between the outer wall 181 and the water source. Subsequently, the flue gas enters the flue pipe 17 through the pipe inlet 182. The steel-copper composite spiral heat-conducting plates 172 heat the outer wall 171 of the flue pipe. Simultaneously, the ventilation holes 173 disrupt the flow rate and trajectory of the flue gas, resulting in sufficient heat transfer. The outer wall 171 of the flue is flushed to raise the temperature of the flue.

At the same time, it absorbs the heat of the flue gas and cools the flue gas, which is discharged through the flue gas outlet pipe 25. The operator operates the control cabinet 3 to turn on the motor 263. The motor 263 drives the ventilation fan 264 to rotate. The rotation of the ventilation fan 264 generates airflow, which draws the flue gas inside the device through the fixed pipe 262 and discharges it. At the same time, external oxygen enters the device through the fixed pipe 262 to supply oxygen to the inside of the heating furnace 12.
