[0002] Clean energy refers to environmentally friendly energy, that is, environmentally friendly, low-emission, and low-pollution energy. The use of clean energy has gradually replaced traditional energy sources such as coal and gasoline. In order to improve energy utilization, it is necessary to use energy recycling to make full use of energy. When clean energy is burned, it is generally necessary to use a dedicated clean energy combustion and heating device.

[0003] Nowadays, natural gas, a clean energy, is widely used, such as natural gas water heaters. However, the waste heat generated by the existing clean energy heating devices on the market is rarely used, which wastes resources. In addition, the flue gas generated by the heating devices is basically discharged directly into the air without being filtered. Although clean energy such as natural gas has less pollution, there will still be a small amount of smoke and particulate matter in the flue gas, which will cause pollution to the nearby environment and reduce the safety and practicality of the equipment.

[0004] To this end, a clean energy heating device is proposed. Utility Model Content

DETAILED DESCRIPTION

[0024] 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.

[0025] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0026] Reference Figures 1 to 3 As shown, this embodiment provides a clean energy heating device, including:

[0027] A heating part, wherein a water pipe 1 is provided through the heating part, a heating pipe 2 is sleeved on the water pipe 1, and the heating pipe 2 is located in the heating part;

[0028] A dust removal part, one end of which is connected to the top of the heating part through an air inlet pipe 3, and the other end is connected to a connecting pipe 4, to which an induced draft fan 5 is fixed;

[0029] The preheating part is sleeved on the water inlet side of the water pipe 1. One end side of the preheating part is connected with the dust removal part through a connecting pipe 4, and the other end side is connected with an air outlet pipe 6.

[0030] The heating part heats the heating tube 2, and the heating tube 2 heats the water pipe 1 inside it, and heats the water flowing through the water pipe 1. The high-temperature flue gas generated after heating enters the dust removal part through the air inlet pipe 3, and is dusted by the dust removal part. The clean high-temperature gas after dust removal is guided by the induced draft fan 5 and enters the preheating part through the connecting pipe 4. The preheating part is wrapped on the outside of the water inlet end of the water pipe 1 to preheat the water that has not yet entered the heating part for heating. This device first cleans and removes the high-temperature flue gas generated by the combustion of clean energy, reduces the content of particulate matter therein, and reduces the pollution to the environment after its emission, which is more environmentally friendly. The high-temperature flue gas after dust removal is transmitted to the front end of the water pipe 1, and the water to be heated in the water pipe 1 is preheated in advance, which reasonably utilizes the waste heat generated by the heating part, so that the energy generated by the combustion of clean energy is more fully utilized, and a better heating effect is achieved.

[0031] According to a further optimized solution, the heating part includes a heating shell 7, a water pipe 1 passes through both ends of the heating shell 7, a nozzle 8 is provided at the bottom end of the heating shell 7, a gas pipeline 9 is connected to the bottom of the nozzle 8, and an ignition needle 10 is fixedly connected to the heating shell 7 on one side of the nozzle 8.

[0032] The gas pipeline 9 transmits clean energy such as natural gas to the nozzle 8 for spraying out, and at the same time, the ignition needle 10 ignites the natural gas to heat the heating tube 2 above the nozzle 8.

[0033] According to a further optimized solution, one end of the gas pipeline 9 away from the nozzle 8 passes through the heating shell 7 and is fixedly connected with a gas regulating valve 11 .

[0034] The gas regulating valve 11 can adjust the speed and size of the gas delivery, thereby controlling the heating power of the heating part.

[0035] According to a further optimized solution, a plurality of air holes 12 are provided on the outer wall of the heating shell 7 , and a dustproof net 13 is fixedly connected to the air holes 12 .

[0036] After combustion in the heating shell 7, oxygen will be consumed, and external air can be promptly replenished into the heating shell 7 from the air vents 12 to provide oxygen for combustion; the dustproof net 13 can prevent external flying insects and impurities from entering from the air vents 12.

[0037] A further optimized solution is provided, in which the dust removal part comprises a dust removal shell 14, a dust outlet 15 is provided at the bottom of the dust removal shell 14, a dust receiving box 16 is detachably connected below the dust outlet 15, the air inlet pipe 3 is connected to the bottom side of the dust removal shell 14, and the connecting pipe 4 is connected to the top side of the dust removal shell 14; a mounting plate 17 is fixedly connected inside the dust removal shell 14, a plurality of cloth bags 18 are fixedly connected to the mounting plate 17, the bottom of the cloth bag 18 is open, and the top is closed; the outer side of the bottom of the cloth bag 18 is fixedly connected to the mounting plate 17, and the top is hung on the top surface of the dust removal shell 14 by a chain 19.

[0038] After entering the dust removal shell 14, large particles of impurities can directly fall from the ash outlet 15. The induced draft fan 5 creates negative pressure on one side of the top of the dust removal shell 14, and the remaining small particles are sucked into the cloth bag 18 along with the flue gas. The surface of the cloth bag 18 has fiber gaps, which plays a capturing role and limits the dust to the surface of the cloth bag 18. The clean high-temperature gas passes through the cloth bag 18 and is pushed into the preheating section by the induced draft fan 5; after the heating and combustion are stopped, the induced draft fan 5 will also stop when the heating stops, and then the pressure at the cloth bag 18 will decrease, and the dust originally adsorbed on the surface of the cloth bag 18 will fall from the ash outlet 15 to the ash receiving box 16. In the later stage, it is necessary to regularly remove impurities in the ash receiving box 16 and regularly clean and replace the cloth bag 18.

[0039] According to a further optimized solution, the preheating part includes a preheating shell 20, which is covered on the outer side of the water pipe 1 near the water inlet end. The interior of the preheating shell 20 is hollow, and both ends of the preheating shell 20 are sealedly connected to the water pipe 1.

[0040] The preheating shell 20 is connected with the dust-removed high-temperature gas. The high-temperature gas surrounds a section of the water pipe 1 along the preheating shell 20 and exchanges heat with the water in the water pipe 1.

[0041] According to a further optimized solution, the end of the preheating shell 20 away from the water inlet end of the water pipe 1 is connected to the connecting pipe 4 , and the end close to the water inlet end of the water pipe 1 is connected to the air outlet pipe 6 .

[0042] With such arrangement, the flow direction of the high-temperature gas in the preheating shell 20 is opposite to that of the water flow. As the water flows, the temperature of the water in contact with the gas gradually increases, which is more conducive to heat exchange and to fully utilizing the thermal energy in the high-temperature gas.

[0043] According to a further optimized solution, a plurality of heat-conducting fins 21 are circumferentially fixedly connected between the preheating shell 20 and the outer wall of the water pipe 1 .

[0044] The heat-conducting fins 21 can speed up the heat exchange efficiency between the high-temperature gas and the water in the water pipe 1, so that the water can obtain more heat in a short time when flowing through the preheating part.
