Description

Technical Field

[0001] The utility model relates to the technical field of boilers, in particular to a high-efficiency energy-saving boiler. Background Art

[0002] A boiler is an energy conversion device. The energy input to the boiler includes chemical energy and electrical energy in the fuel. The boiler outputs steam, high-temperature water or organic heat carrier with a certain amount of thermal energy. The original meaning of pot refers to a water container heated on fire, and furnace refers to a place where fuel is burned. The boiler consists of two parts: pot and furnace. The hot water or steam produced in the boiler can directly provide the required thermal energy for industrial production and people's lives, or it can be converted into mechanical energy through a steam power device, or the mechanical energy can be converted into electrical energy through a generator. The boiler that provides hot water is called a hot water boiler, which is mainly used for life and has a small number of applications in industrial production. The boiler that produces steam is called a steam boiler, often referred to as a boiler. It is a device that uses the heat energy released by fuel combustion or other heat energy to heat the working medium water or other fluids to certain parameters; the boiler is divided into two parts, "pot" and "furnace". The pot is a pressurized component that holds water and steam, and heats, vaporizes and separates water from steam. The furnace is a place where fuel combustion or other heat energy is released, with combustion equipment, combustion chamber, furnace and heat release flue, etc. The pot and the furnace are both carrying out the process of heat conversion. The interface between heat release and heat absorption is called the heating surface. The main working principle of the boiler is that it is a thermal equipment that uses the heat energy released after fuel combustion or the waste heat in industrial production to transfer to the water in the container to make the water reach the required temperature or a certain pressure steam.

[0003] After searching, a Chinese patent with publication number CN217899923U discloses a boiler energy-saving device, including a boiler body, a smoke exhaust pipe and a steam exhaust pipe are fixedly connected to the top of the boiler body, and a waste heat recovery component is provided on one side of the boiler body; and a Chinese patent with publication number CN208074931U discloses a boiler economizer, including a boiler, and the boiler includes a hot water inlet and a hot water outlet, and the hot water inlet is connected to a cold water tank.

[0004] However, the prior art still has certain deficiencies when used, such as:

[0005] First, in the prior art, when heat exchange is performed, the heat exchange method is mostly vertical heat exchange, rather than cyclone heat exchange, which will lead to insufficient heat exchange;

[0006] 2. In the prior art, when heat exchange is performed, low-temperature water is generally used to exchange heat with high-temperature flue gas, and high-temperature water is generally used to exchange heat with low-temperature flue gas. This heat exchange method will lead to unequal heat exchange, and then lead to insufficient heat exchange.

[0007] The above contents are only used to assist in understanding the technical solution of the present utility model, and do not constitute an admission that the above contents are the closest prior art. Utility Model Content

[0008] The utility model provides a high-efficiency energy-saving boiler with cyclone heat exchange, heat exchange between high-temperature water and high-temperature flue gas, heat exchange between low-temperature water and low-temperature flue gas, and the beneficial effect of sufficient heat exchange without wasting heat energy, solving the problem of insufficient heat exchange mentioned in the above background technology.

[0009] To achieve the above purpose, the utility model provides the following technical solutions: a high-efficiency energy-saving boiler, comprising:

[0010] A boiler assembly comprises a furnace body, and a combustion chamber, a heat exchange chamber and a conveying chamber arranged inside the furnace body, wherein a plurality of flue gas ducts are arranged inside the heat exchange chamber;

[0011] A conveying assembly, comprising a feed hopper, a discharge hopper, and a conveyor belt mounted on the furnace body;

[0012] The heat exchange component comprises a heat exchange water filled in the gap of the flue gas duct, a conversion component arranged on the rear surface of the furnace body, and a high-temperature pipe and a low-temperature pipe arranged inside the furnace body and the conversion component.

[0013] By setting up the above-mentioned technical scheme, the heat in the flue gas can be absorbed and then converted into a heat source to drive the radiator when it is working. By reducing the energy consumption of the radiator when it is working, the purpose of high efficiency and energy saving can be achieved. At the same time, the problem of waste of resources caused by direct emission of flue gas can also be avoided. In addition, by setting up hot water exchange for energy conversion, the conversion cost is low. At the same time, through the circulation of hot water exchange, the flue gas can be treated. The operation is relatively simple and easy to implement and use.

[0014] As an optional solution of a high-efficiency energy-saving boiler of the utility model, the combustion chamber and the heat exchange chamber are both opened on the top of the conveying chamber, and an observation window is arranged on the furnace body relative to the position of the combustion chamber.

[0015] By setting the above technical scheme, the combustion chamber and the heat exchange chamber are both opened on the top of the conveying chamber, so that the fuel can fall directly into the conveying chamber after combustion. Through the conveying chamber, the ash produced after the fuel combustion can be directly transported to the heat exchange chamber for heat exchange. The layout is reasonable and convenient for the overall operation. By setting an observation window, the combustion situation can be observed to determine whether it is necessary to add fuel again.

[0016] As an optional solution of a high-efficiency energy-saving boiler of the utility model, the feed hopper is arranged relative to the position of the combustion chamber, the discharge hopper is arranged relative to the position of the heat exchange chamber, and the conveyor belt is installed inside the conveying chamber.

[0017] By setting up the above technical scheme, the fuel can be directly transported to the interior of the combustion chamber through the feed hopper. After the fuel is burned, the ash is transported to the interior of the heat exchange chamber through the conveyor belt inside the conveyor for heat exchange. The ash after heat exchange can be discharged through the discharge hopper. The overall structure is relatively compact, so that the overall device occupies a small area and is easy to carry and use, which greatly increases the practicability of the device.

[0018] As an optional solution for a high-efficiency energy-saving boiler of the utility model, a fan is arranged on the rear surface of the furnace body, an air duct is installed on the fan, the fan is detachably connected to the furnace body through the air duct, one end of the air duct passes through the interior of the conveying chamber, and the air duct is arranged relative to the position of the conveyor belt.

[0019] By setting up the above-mentioned technical scheme, by setting up a fan and an air duct, the ash transported to the heat exchange chamber on the conveyor belt can be blown, so that the ash can be burned more thoroughly, thereby further increasing the temperature of the flue gas generated by the ash, thereby increasing the temperature of the hot water for heating, and making more thorough use of resources. The fan is detachably connected to the furnace body through the air duct, so that when the fan is damaged, it can be easily disassembled, repaired or replaced. At the same time, the fan and the air duct can also be disassembled when the furnace body needs to be moved.

[0020] As an optional solution of the high-efficiency energy-saving boiler of the utility model, a partition is provided inside the heat exchange chamber relative to the flow direction of the hot water.

[0021] By providing the above technical solution, the hot water can be guided and limited by the partition during heat exchange.

[0022] As an optional solution of the high-efficiency energy-saving boiler of the utility model, the conversion component includes a heat exchange box connected to the high-temperature pipe and the low-temperature pipe, and a radiator is installed on the heat exchange box.

[0023] By setting up the above technical scheme, the heat of the hot water can be absorbed by the radiator during the thermal energy conversion, thereby completing the energy conversion. By setting up a heat exchange box, the hot water can be recycled, thereby making the overall heat exchange system of the device more perfect.

[0024] As an optional solution for a high-efficiency energy-saving boiler of the utility model, water pumps are fixedly installed on the heat exchange box at positions relative to the high-temperature pipeline and the low-temperature pipeline.

[0025] By setting up the above technical scheme and the water pump, it is convenient to extract the high-temperature hot water after absorbing flue gas from the furnace body when the hot water is circulated, and to introduce the low-temperature hot water after being absorbed by the radiator into the furnace body again.

[0026] As an optional solution of the utility model for a high-efficiency energy-saving boiler, a dome is arranged on the top of the conveying chamber, a heat-resistant plate is arranged on the dome, and the heat-resistant plate is cement high-aluminum aggregate.

[0027] By setting up the above technical scheme, since the conveyor belt is currently driven by a motor, the motor will be overloaded and damaged in an overheated environment, and the conveyor belt will also soften under high temperature. Therefore, by setting up an arch and a heat-resistant plate, a better heat insulation effect can be achieved, thereby increasing the service life of the conveyor belt.

[0028] As an optional solution of the utility model for a high-efficiency energy-saving boiler, a smoke outlet pipe is provided on the furnace body, and the flow direction of the hot water is opposite to the discharge direction of the smoke in the smoke pipe.

[0029] By setting up the above technical scheme and setting up a smoke outlet pipe, it is convenient to discharge the smoke. By making the flow direction of the hot water opposite to the discharge direction of the smoke in the smoke pipe, the heat of the smoke can be fully absorbed, thereby effectively avoiding energy loss.

[0030] As an optional solution of the high-efficiency energy-saving boiler of the utility model, the feed hopper and the discharge hopper are connected end to end with the conveyor belt.

[0031] By providing the above technical solution, the loading of fuel and the transportation and unloading of ash are facilitated.

[0032] The utility model has the following beneficial effects:

[0033] 1. This high-efficiency energy-saving boiler can guide the flow direction of the hot water by setting a baffle. The flow direction of the hot water is opposite to the discharge direction of the flue gas. When absorbing the heat of the flue gas, the heat in the flue gas can be fully absorbed by the hot water. The high-temperature water exchanges heat with the high-temperature flue gas, and the low-temperature water exchanges heat with the low-temperature flue gas. At the same time, the heat exchange method is cyclone heat exchange, which can fully exchange heat and avoid the problem of insufficient heat exchange.

[0034] 2. This high-efficiency energy-saving boiler can supply air to the fuel on the conveyor belt by setting a fan and an air duct, so that the ash can be fully burned, thereby further increasing the temperature of the flue gas during emission and avoiding the occurrence of incomplete combustion of the fuel in the ash produced after the fuel is burned.

[0035] 3. This high-efficiency energy-saving boiler can absorb the heat in the flue gas by filling the hot water in the gap of the flue gas duct. The hot water after absorbing the heat is transported to the inside of the heat exchange box through a high-temperature pipe to operate the heat exchanger plate. By converting the heat in the flue gas into the heat of the radiator, the electric energy of the radiator can be reduced when it is working, thereby playing a role of high efficiency and energy saving to a certain extent, solving the problem of energy waste caused by direct flue gas discharge in the prior art.

[0036] 4. This high-efficiency energy-saving boiler, after the heat in the hot water is absorbed by the radiator, is transported back into the furnace body through the low-temperature pipe, and then absorbs heat from the flue gas again. By reusing the hot water, the heat in the emitted flue gas can be absorbed again. By reciprocating the use of circulating water, the heat of the emitted flue gas can be absorbed. The device has a simple structure and is easy to operate.

[0037] 5. The high-efficiency energy-saving boiler is provided with a water pump, which makes it easy to extract the high-temperature hot water after absorbing flue gas from the furnace body when the hot water is circulated, and to introduce the low-temperature hot water after being absorbed by the radiator into the furnace body again.

[0038] 6. This high-efficiency energy-saving boiler can play a better heat-insulating role by setting up the arch and heat-resistant plate, thereby increasing the service life of the conveyor belt. BRIEF DESCRIPTION OF THE DRAWINGS

[0053] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0054] Example:

[0055] See also Figure 1-Figure 6 A high-efficiency energy-saving boiler includes a boiler assembly 100, a conveying assembly 200 and a heat exchange assembly 300. The boiler assembly 100 includes a furnace body 101, and a combustion chamber 102, a heat exchange chamber 103 and a conveying chamber 104 opened inside the furnace body 101. A plurality of flue gas ducts 105 are arranged inside the heat exchange chamber 103; the conveying assembly 200 includes a feed hopper 201, a discharge hopper 202 and a conveyor belt 203 installed on the furnace body 101. The feed hopper 201 and the discharge hopper 202 are connected to the conveying belt 203. The bucket 202 is connected to the conveyor belt 203 end to end; the heat exchange assembly 300 includes hot water filled in the gap of the flue gas duct 105, a conversion assembly 303 arranged on the rear surface of the furnace body 101, and a high-temperature pipe 301 and a low-temperature pipe 302 arranged inside the furnace body 101 and the conversion assembly 303; the conversion assembly 303 includes a heat exchange box 3031 connected to the high-temperature pipe 301 and the low-temperature pipe 302, and a radiator 3032 is installed on the heat exchange box 3031;

[0056] It should also be noted that a smoke outlet pipe is provided on the furnace body 101, and the flow direction of the hot water is opposite to the discharge direction of the smoke, so that high-temperature water can exchange heat with high-temperature smoke, and low-temperature water can exchange heat with low-temperature smoke, so that heat exchange can be fully performed;

[0057] In this embodiment, when in use, the fuel is first transported to the interior of the combustion chamber 102 through the feed hopper 201 for combustion. The ash generated after combustion is transported to the position of the heat exchange chamber 103 through the conveyor belt 203 in the conveying chamber 104. The smoke generated by the ash is discharged through the smoke duct 105 and the smoke outlet pipe. During the smoke discharge process, the heat in the smoke can be absorbed by the hot water filled in the gap of the smoke duct 105. Since the flow direction of the hot water is opposite to the discharge direction of the smoke, the hot water can fully absorb the heat in the smoke. The hot water after absorbing heat enters the interior of the heat exchange box 3031 through the high-temperature pipe 301 to heat the radiator 3032 (the flow direction of the smoke is as shown in FIG. Figure 5 As shown), the heat exchange water achieves the purpose of heat dissipation. After heat dissipation, the heat exchange water re-enters the interior of the furnace body 101 through the low-temperature pipe 302 for further heat exchange (the flow direction of the heat exchange water is as shown in FIG. Figure 4 As shown), during the heat exchange process, high-temperature water is used to exchange heat with high-temperature flue gas, and low-temperature water is used to exchange heat with low-temperature flue gas. At the same time, the flow trajectories of the hot water and flue gas are both curves, so the heat exchange energy can be fully carried out, so that the waste heat can be recycled and utilized, which plays a role in high efficiency and energy saving. Finally, the ash can be discharged through the discharge hopper 202.

[0058] Furthermore, the combustion chamber 102 and the heat exchange chamber 103 are both opened at the top of the conveying chamber 104, and an observation window is provided on the furnace body 101 relative to the combustion chamber 102. By setting the observation window, the combustion situation can be observed; the feed hopper 201 is arranged relative to the position of the combustion chamber 102. Through such arrangement, the fuel can be burned after loading, and the discharge hopper 202 is arranged relative to the position of the heat exchange chamber 103. Through such arrangement, the ash can be cleaned and discharged after the waste heat of the flue gas is recovered. The conveyor belt 203 is installed inside the conveying chamber 104. Through such arrangement, the ash is convenient to be transported, so that the ash is transported from the combustion chamber 102 to the heat exchange chamber 103 to recover the waste heat of the flue gas generated by it.

[0059] Furthermore, a fan 400 is provided on the rear surface of the furnace body 101, and an air duct 500 is installed on the fan 400. The fan 400 is detachably connected to the furnace body 101 through the air duct 500. One end of the air duct 500 passes through the interior of the conveying chamber 104. The air duct 500 is arranged relative to the position of the conveyor belt 203. Through such an arrangement, air can be supplied to the fuel on the conveyor belt 203, thereby allowing the ash to be fully burned; a partition 800 is arranged inside the heat exchange chamber 103 relative to the flow direction of the hot water. By setting the partition 800, the hot water can be guided.

[0060] Furthermore, water pumps 3033 are fixedly installed on the heat exchange box 3031 at positions relative to the high-temperature pipe 301 and the low-temperature pipe 302. The water pump 3033 is provided to facilitate the circulation of hot water. A dome 600 is provided on the top of the conveying chamber 104, and a heat-resistant plate 700 is provided on the dome 600. The heat-resistant plate 700 is cement high-aluminum aggregate. By providing the dome 600 and the heat-resistant plate 700, a better heat insulation effect can be achieved, thereby increasing the service life of the conveyor belt 203.

[0061] Working principle: When in use, the fuel is first transported to the interior of the combustion chamber 102 through the feed hopper 201 for combustion. The ash produced after combustion is transported to the position of the heat exchange chamber 103 through the conveyor belt 203 in the conveying chamber 104. The smoke generated by the ash is discharged through the smoke duct 105 and the smoke outlet pipe. During the smoke discharge process, the heat in the smoke can be absorbed by the hot water filled in the gap of the smoke duct 105. Since the flow direction of the hot water is opposite to the discharge direction of the smoke, the hot water can fully absorb the heat in the smoke. The hot water after absorbing heat enters the interior of the heat exchange box 3031 through the high-temperature pipe 301 to heat the radiator 3032 (the flow direction of the smoke is as shown in FIG. Figure 5 As shown), the purpose of heat dissipation is achieved by using the hot water exchange. When the ash is transported to the inside of the heat exchange chamber 103 through the conveyor belt 203, the ash can be blown by the fan 400 and the air duct 500, so that the ash can be burned more thoroughly, thereby further increasing the temperature of the smoke generated by the ash, thereby increasing the temperature of the hot water exchange, and making more thorough use of resources. In addition, the combustion situation can be observed by setting an observation window, and the hot water exchange can be guided by setting a partition 800;

[0062] After the heat is dissipated, the heat exchange water re-enters the interior of the furnace body 101 through the low-temperature pipe 302 for further heat exchange (the flow direction of the heat exchange water is as follows). Figure 4 As shown), when the cooled hot water enters the furnace body 101, it absorbs the heat of the flue gas again, and the hot water after absorbing the heat again heats the radiator 3032. The hot water circulates, so that the waste heat can be recycled. By converting the heat in the flue gas into the heat of the radiator, the electric energy of the radiator can be reduced during operation, thereby achieving a high efficiency and energy saving effect to a certain extent. Finally, the ash can be discharged through the discharge hopper 202. In addition, by arranging the arch 600 and the heat-resistant plate 700, a better heat insulation effect can be achieved, thereby increasing the service life of the conveyor belt 203 (currently the conveyor belt is driven by a motor, and by insulating the space where the conveyor belt is located, the service life of the motor can be increased, thereby increasing the service life of the conveyor belt).

Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0064] The above is only a preferred embodiment of the present invention.
