Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of energy-saving stoves, in particular to a high-efficiency energy-saving stove with anti-fouling and easy cooling. BACKGROUND

[0002] The heating principle of the stove is to ignite high-pressure natural gas through the atmosphere to heat the bottom of the pot. Due to the long duration of use and high temperature, the wall of the stove will maintain a very high temperature for a long time, so it is necessary to continuously introduce cooling water into the wall of the stove to continuously cool the stove to ensure the use stability and service life of the stove. However, in actual use, the cooling water in the wall of the stove is in a boiling state, and the cooling water is usually tap water. Due to the difference in water bodies, scale will be formed in the cooling cavity of the stove, and the heat conduction capacity of the scale is very poor. If the scale formed in the stove is too thick, it will reduce the cooling efficiency of the stove, and in severe cases, it will cause safety hazards, threatening the life and property safety of the user. Therefore, the stove needs to be regularly cleaned by maintenance personnel to ensure the use stability of the stove, but the maintenance operation is complicated, and the inner wall of the stove is usually cleaned with acid, which will corrode the inner wall of the stove after multiple maintenance, thereby affecting the service life of the stove.

[0003] To solve the above technical problems, Chinese patent CN112556218A discloses a downhole micro-geothermal power generation system, which comprises a support shell, a steam delivery frame, a steam turbine, a generator, a condenser and a mounting cavity. In the present application, the second sleeve and the third sleeve in the steam delivery frame can rotate under the driving of water vapor, thereby scraping and removing the dirt, achieving self-cleaning of the dirt, effectively prolonging the service life of the device, and the steam delivery frame can also heat the heat transfer cavity, effectively improving the heating efficiency of the intermediate medium cavity, thereby improving the power generation efficiency. The steam delivery frame can be regularly pulled upwards to achieve quick disassembly of the steam delivery frame, and then the steam delivery frame can be cleaned and descaled, which is more efficient and does not affect the normal operation of the power generation system. The flexible sector plate rotates to strengthen the shielding range of the bottom of the support shell and further improve the anti-fouling effect of the bottom of the support shell. The above-mentioned patent uses steam to drive the descaling device to remove the scale, but the descaling efficiency is low, and a large part of the steam is lost in the process of driving the descaling device, thereby causing waste of resources.

[0024] Further, the furnace 11 is opened downward from the stove 10 in a plan view, and the furnace 11 has a square structure and is provided with a slope at the opening thereof; when the pot is placed on the furnace 11, the square structure of the furnace 11 makes the bottom wall of the pot not contact all the four side walls of the furnace 11, so that a large gap is formed between the pot and part of the side walls of the furnace 11, facilitating air flow, ensuring that the gas can be fully burned, and further improving the use effect of the gas jet head 12.

[0025] Further, the stove 10 is further provided with a gas pipeline 18, the gas jet head 12 is installed at the end of the gas pipeline 18 and is in communication with the gas pipeline 18, the gas pipeline 18 is in communication with the high-pressure gas, and the gas pipeline 18 is filled with a heat insulation filler 19 between the wall of the stove 10, and preferably, the heat insulation filler 19 includes but is not limited to asbestos.

[0026] Please refer to Figure 3 , Figure 4 , the stove 10 has a square structure, and the wall of the stove 10 is provided with a cooling cavity 13, a heat exchange cavity 14 and a steam cavity 15 from bottom to top. The cooling cavity 13, the heat exchange cavity 14 and the steam cavity 15 are in communication in sequence.

[0027] Further, the cooling cavity 13 is located at the bottom of the stove 10 and surrounds the gas pipeline 18, and the cooling cavity 13 is filled with a cooling liquid, and preferably, the cooling liquid includes but is not limited to water. In this embodiment, the cooling cavity 13 is circumscribed by a water pipe (not shown in the figure), so as to continuously fill water into the cooling cavity 13, and ensure the use stability of the present application.

[0028] Further, the heat exchange cavity 14 is located above the cooling cavity 13 and surrounds the furnace 11, and a separation filter screen 17 is arranged between the heat exchange cavity 14 and the cooling cavity 13, and the separation filter screen 17 is detachably connected in the stove 10, and preferably, the separation filter screen 17 has a filter aperture of 500-2000 μm. In use, the gas jet head 12 generates a large amount of heat, so that the wall of the furnace 11 is in a high-temperature state for a long time, the cooling liquid in the cooling cavity 13 is filled into the heat exchange cavity 14, and then the wall of the furnace 11 is cooled, so as to prevent damage.

[0029] Further, the steam cavity 15 is located above the heat exchange cavity 14 and surrounds the slope of the furnace 11, and the stove 10 is externally provided with a delivery pipe 21, one end of the delivery pipe 21 penetrates through the wall of the stove 10 and is in communication with the steam cavity 15, and the other end of the delivery pipe 21 is in communication with the heat exchange cavity 14 and the cooling cavity 13, respectively.

[0030] Specifically, the conveying pipe 21 comprises a descaling conveying section 211 and a backwater conveying section 212, the backwater conveying section 212 is in communication with the descaling conveying section 211, one end of the descaling conveying section 211 is in communication with the steam cavity 15, the other end of the descaling conveying section 211 is in communication with the heat exchange cavity 14, and the backwater conveying section 212 is in communication with the cooling cavity 13. The backwater conveying section 212 is located below the descaling conveying section 211, so as to ensure that the condensed water is received and conveyed into the cooling cavity 13.

[0031] In use, the gas nozzle 12 generates a large amount of heat, so that the wall of the hearth 11 is in a high-temperature state for a long time, and then the water in the heat exchange cavity 14 is heated to boiling and generates a large amount of steam, which rises into the steam cavity 15 and enters the conveying pipe 21.

[0032] In the embodiment, the cooktop 10 further comprises a temperature insulation cavity 16, and the temperature insulation cavity 16 is provided with a heat insulation structure, part of the temperature insulation cavity 16 is located between the cooling cavity 13 and the outer wall of the cooktop 10, and the other part of the temperature insulation cavity 16 is located between the heat exchange cavity 14 and the outer wall of the cooktop 10. The temperature insulation cavity 16 is connected with a fan, and in use, the fan is used to introduce air into the temperature insulation cavity 16 and circulate and discharge the air. In the process of air circulation, the heat generated by the cooling cavity 13 and the heat exchange cavity 14 is taken away, so as to reduce the heat transfer to the outer wall of the cooktop 10, prevent the operator from being scalded, and improve the use stability and safety of the cooktop 10.

[0033] In another embodiment, the temperature insulation cavity 16 is filled with a temperature insulation material, such as asbestos. The heat generated by the cooling cavity 13 and the heat exchange cavity 14 is blocked, so as to prevent the temperature of the outer wall of the cooktop 10 from being too high and scald the operator.

[0034] Further, the conveying pipe 21 is connected with a first elbow pipe 23 at the descaling conveying section 211, the first elbow pipe 23 is provided with a first nozzle 25, the first nozzle 25 penetrates the wall of the cooktop 10 and extends into the heat exchange cavity 14, and the first nozzle 25 is located above the isolation filter screen 17 and faces the side wall of the heat exchange cavity 14. Preferably, the diameter of the first elbow pipe 23 is smaller than the diameter of the descaling conveying section 211, so as to reduce the pipe diameter, improve the pressure, and ensure the steam conveying effect.

[0035] In actual use, the water in the heat exchange cavity 14 is in a continuous boiling state, but the boiling bubbles can only cause the water surface to roll, and the water flow rate inside and at the bottom of the heat exchange cavity 14 is still slow, and the cooling liquid is usually tap water, and scale is generated in the heat exchange cavity 14 due to the water body, and the scale has poor heat conduction capacity, and if the scale formed in the heat exchange cavity 14 is too thick, the cooling efficiency of the stove 10 will be reduced. Generally, scale accumulates on the side wall of the heat exchange cavity 14, therefore, the first spray head 25 is arranged opposite to the side wall of the heat exchange cavity 14 in the present application, steam is introduced into the first spray head 25 through the delivery pipe 21, the steam is sprayed into the heat exchange cavity 14 through the first spray head 25, and then a high-flow-rate water flow is formed on the side wall of the heat exchange cavity 14, and the water in the heat exchange cavity 14 also flows quickly under the driving of the first spray head 25, so that scale cannot accumulate on the side wall of the heat exchange cavity 14, thereby effectively preventing scale accumulation.

[0036] The steam is directly sprayed to stir the water flow in the present application, a high-flow-rate water flow is formed around the wall body, and scale accumulation on the wall body is effectively prevented. Compared with the prior art in which the steam drives the scale removal device to rotate to remove scale, the utilization rate of steam is higher in the present application, and there is no equipment directly contacting the wall body, so that the surface of the wall body is not abraded, the coating of the wall body is protected, and the corrosion prevention effect and service life of the equipment are improved.

[0037] Understandably, the first spray head 25 is a common high-pressure spray head on the market, because the water vapor can cause the pressure in the delivery pipe 21 to rise, therefore, the use stability can be effectively guaranteed by using a high-pressure spray head, and the water vapor sprayed into the heat exchange cavity 14 can drive the cooling liquid to flow quickly. Meanwhile, a one-way valve (not shown in the figure) is arranged in the first spray head 25, the one-way valve controls the steam to flow from the first elbow pipe 23 into the first spray head 25, and prevents the cooling liquid in the heat exchange cavity 14 from flowing.

[0038] In the embodiment, the isolation filter screen 17 is arranged by stacking a plurality of filter cloths, and gaps are formed between the plurality of isolation filter screens 17. During use, the scale is filtered by the isolation filter screen 17 and flows into the gaps, so that the filtering effect is effectively improved. During maintenance, the isolation filter screen 17 only needs to be replaced, the scale can be concentratedly treated, the maintenance difficulty is greatly reduced, and the use convenience of the present application is effectively improved.

[0039] Further, the conveying pipe 21 is communicated with a second elbow pipe 24 at the backwater conveying section 212, the second elbow pipe 24 is provided with a one-way valve 22 and a pressure relief valve (not shown in the figure), and the end of the second elbow pipe 24 is provided with a second nozzle 26 which penetrates the wall of the stove body 10 and extends into the cooling cavity 13. The one-way valve 22 controls the steam or water to flow into the cooling cavity 13 from the second elbow pipe 24 in one direction. Preferably, the one-way valve 22 is an electromagnetic control one-way valve.

[0040] In the embodiment, the electromagnetic control one-way valve 22 is composed of multiple valves including an electromagnetic control valve, a non-return valve and a one-way valve, and is used to control the opening and closing of the backwater conveying section of the conveying pipe 21. When the steam enters the heat exchange cavity 14 from the descaling conveying section 211, the electromagnetic control one-way valve 22 is in a closed state, and the steam entering the second elbow pipe 24 from the backwater conveying section 212 is blocked by the electromagnetic control one-way valve 22. When the steam pressure is too large, the pressure relief valve in the second elbow pipe 24 is opened, and at the same time, the electromagnetic control one-way valve 22 is opened, so that the steam passes through the backwater conveying section 212 and enters the cooling cavity 13, thereby achieving backwater and pressure relief. The second elbow pipe 24 and the second nozzle 26 are added to realize the recovery of steam and water and the adjustment of the first nozzle 25. After the steam enters the conveying pipe 21, part of the steam will be cooled into water, which is discharged into the cooling cavity 13 through the second elbow pipe 24 and the second nozzle 26, thereby realizing water circulation. At the same time, due to the increase of the pressure in the conveying pipe 21 caused by the water vapor, part of the pressure is discharged through the second nozzle 26, so as to prevent the first nozzle 25 from being directly sprayed on the wall of the heat exchange cavity 14 and forming a vacuum due to the excessive pressure of the first nozzle 25, which will cause the cooling liquid near the vacuum to be completely blown away and the wall of the heat exchange cavity 14 to be unable to exchange heat. Therefore, the second nozzle 26 and the pressure relief valve are set to ensure that the pressure of the first nozzle 25 is within a set range, thereby improving the stability of the equipment.

[0041] The specific operation mode of the present application is as follows: step one: place the pot in the hearth 11, and the high-pressure gas is sprayed from the gas nozzle 12 and ignited to heat the pot.

[0042] Step two: fill the cooling cavity 13 and the heat exchange cavity 14 with cooling liquid to cool the wall of the hearth 11. When working, the water in the heat exchange cavity 14 is heated to boiling and generates a large amount of steam which rises into the steam cavity 15 and enters the conveying pipe 21.

[0043] Step three: pass the steam into the first nozzle 25 through the descaling conveying section 211 of the conveying pipe 21, and the steam is sprayed onto the side wall of the heat exchange cavity 14 through the first nozzle 25, thereby forming a high-speed water flow on the side wall of the heat exchange cavity 14 to complete the descaling.

[0044] Step four: when the pressure is too large, the pressure relief valve in the second elbow 24 opens, and the electromagnetic control one-way valve 22 opens, the steam passes through the backwater delivery section 212 and enters the cooling cavity 13, completing the water circulation and pressure relief.

[0045] The present application uses steam to directly spray and stir the water flow, so that a high-speed water flow is formed around the wall body, thereby effectively preventing scale from accumulating on the wall body. Compared with the prior art, which uses steam to drive the scale removal device to rotate to achieve scale removal, the present application has higher utilization of steam, and there is no direct contact between the device and the wall body, so the wall body surface is not abraded, the wall body coating is protected, and the corrosion prevention effect and service life of the device are improved.

[0046] It can be understood that the present application is described by some embodiments, and those skilled in the art know that various changes or equivalent replacements can be made to these features and embodiments without departing from the spirit and scope of the present application. In addition, under the guidance of the present application, these features and embodiments can be modified to adapt to specific conditions and materials without departing from the spirit and scope of the present application. Therefore, the present application is not limited by the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of the present application are within the scope of the present application.
