DETAILED DESCRIPTION

[0022] The following is a detailed description of a biomass water heater with high heat exchange efficiency provided by the utility model in combination with the accompanying drawings and specific embodiments. At the same time, it is explained here that in order to make the embodiments more detailed, the following embodiments are the best and preferred embodiments, and those skilled in the art may also adopt other alternative methods to implement some known technologies; and the accompanying drawings are only for more specific description of the embodiments, and are not intended to specifically limit the utility model.

[0023] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, an embodiment of the utility model provides a biomass water heater with high heat exchange efficiency, including a water heater body 1, the inner cavity of the water heater body 1 forms a furnace 10 through a partition, a rotating mechanism 12 is installed in the furnace 10, the rotating mechanism 12 includes a stepper motor 1201, the output end of the stepper motor 1201 is installed with four baffles 1202 through a rotating rod 1203, two inclined plates 1204 are installed in the furnace 10, and multiple return combustions are arranged in the furnace 10.

[0024] like Figure 1 , Figure 2 and Figure 3 As shown, the furnace 10 is provided with a dust cleaning frame 14, the side of the water heater body 1 is connected to a blower 9, and the surface of the water heater body 1 is provided with a furnace door.

[0025] The function of the blower 9 is to supply an appropriate amount of air into the furnace 10 to ensure that the biomass fuel can be fully burned. The oxygen provided by the blower 9 can promote the combustion reaction of the fuel and improve the combustion efficiency, thereby increasing the heat output of the water heater. Sufficient air flow can help the fuel to burn fully and reduce the smoke and harmful gases produced by incomplete combustion. By adjusting the air volume of the blower 9, the speed and intensity of the combustion can be controlled to ensure that the water heater operates in a safe and efficient state.

[0026] like Figure 1 , Figure 2 and Figure 3 As shown, the inner cavity of the water heater body 1 is provided with a water tank 11 and a preheating tank 8, and the water tank 11 is connected with the preheating tank 8 through a water pump and a connecting pipe.

[0027] The main function of the preheating box 8 is to preheat the water entering the boiler to improve thermal efficiency and save energy. By preheating cold water, the energy required for the boiler to heat to the set temperature can be reduced, thereby improving the thermal efficiency of the entire system. When cold water directly enters a high-temperature environment, a large temperature difference will be generated, resulting in increased thermal stress of the material. Preheating helps to reduce this temperature difference and protect the boiler material from thermal stress damage.

[0028] like Figure 2 and Figure 3 As shown, the inner cavity of the preheating box 8 is provided with a smoke exhaust pipe 13, and both ends of the smoke exhaust pipe 13 pass through the preheating box 8 and are connected with the furnace 10.

[0029] The main function of the flue gas duct 13 is to exhaust the exhaust gas generated by the combustion of biomass in the furnace 10, and at the same time use the heat of these exhaust gases to heat the water in the preheating box 8. The flue gas duct 13 guides the high-temperature flue gas generated in the furnace 10 to the preheating box 8. During the flow of the flue gas, its heat is absorbed by the water in the preheating box 8, realizing the recovery and utilization of heat energy, improving the energy efficiency of the entire system, and can significantly improve the preheating efficiency, reduce the heat that the boiler itself needs to generate, and save energy consumption. At the same time, the temperature of the flue gas will be reduced, which helps to reduce the temperature of the flue gas emissions, reduce thermal pollution, and meet environmental protection requirements.

[0030] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, a water inlet pipe 4 is provided through the top of the water heater body 1 , and the water inlet pipe 4 is connected to the preheating box 8 . A filtering mechanism 7 is provided on the top of the water heater body 1 , and the filtering mechanism 7 includes a filtering box 701 .

[0031] The filter mechanism 7 is used to filter impurities in the exhausted exhaust gas to reduce air pollution.

[0032] like Figure 1, Figure 2 , Figure 3 and Figure 5 As shown, the inner cavity of the filter box 701 is provided with a filter screen plate 703 and an adsorption screen plate 702 through a clamping block 704, a draft fan 3 is provided on the side of the filter box 701 close to the adsorption screen plate 702, and the smoke exhaust pipe 13 is connected to the side of the filter box 701 close to the filter screen plate 703.

[0033] The main function of the filter screen 703 is to serve as a physical interception barrier. It is composed of a series of fine mesh holes and can effectively intercept larger particulate impurities in the exhaust gas, such as dust, soot and other suspended matter. If these impurities are directly discharged into the atmosphere without filtering, they will not only pollute the environment, but also may cause harm to human health. The filter screen 703 captures these particulate matter and prevents them from being discharged with the exhaust gas, thereby protecting the environment and human health. The adsorption screen 702 is used to adsorb impurities, which not only plays an important role in environmental protection, but also improves the overall efficiency of the water heater system. When the harmful substances in the exhaust gas are adsorbed, the corrosion of pipes and equipment can be reduced, their service life can be extended, and the thermal efficiency of the heat exchanger can be maintained. In addition, the use of activated carbon as the adsorption material can also reduce the noise of the water heater to a certain extent because it can absorb part of the sound wave energy.

[0034] like Figure 1 , Figure 2 and Figure 3 As shown, a controller 2 is arranged on the surface of the water heater body 1, and the controller 2 includes a display screen and control buttons. A detection mechanism 5 is arranged on the top of the water heater body 1, and the detection mechanism 5 includes a pressure detector, a temperature detector and an alarm. A pressure relief pipe 6 is arranged on the side of the water heater body 1.

[0035] The detection mechanism 5 can monitor the operating status of the water boiler in real time, including key parameters such as the water temperature and pressure in the boiler, which helps to ensure that the water boiler operates under safe and optimal working conditions. By continuously monitoring the pressure and temperature of the boiler, the detection mechanism 5 can issue timely warnings when the parameters exceed the safe range, prevent accidents, and ensure the safety of operators and equipment.

[0036] The technical solution provided by the utility model is to add water into the preheating box 8 through the water inlet pipe 4, and the water in the preheating box 8 is timely supplemented to the water tank 11 through the water pump and the connecting pipe. The blower 9 blows air into the furnace 10, so that the biomass in the furnace 10 is fully burned, and the stepper motor 1201 drives the baffle 1202 to rotate through the rotating rod 1203, so that the ash in the furnace 10 falls into the cleaning frame 14, and the gas after the biomass in the furnace 10 is burned through multiple return passes is discharged through the exhaust gas pipe 13, the filter mechanism 7 and the induced draft fan 3.

[0037] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the above preferred embodiments of the present invention, and those skilled in the art can fully understand the present invention without the description of these details. In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.

[0038] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
