Technical Field

[0001] This invention belongs to the field of wall-hung boiler technology, specifically relating to an integrated structure for air filtration and rainwater collection, and a gas-fired wall-hung boiler. Background Technology

[0002] A gas-fired wall-hung boiler is a common name for a national standard gas-fired wall-mounted rapid heating and water heater. It has dual functions of heating and domestic hot water supply. Its core components include a burner, heat exchanger, and circulating water pump. The burner mixes natural gas with air and then heats cold water, with the resulting flue gas being discharged from the flue pipe. Typically, the flue pipe is slightly angled upwards for exhaust purposes. In existing gas-fired wall-hung boilers, the exhaust pipe and air inlet pipe can be separate or coaxial. Regardless of the configuration, when air enters through the air inlet pipe, it carries particulate matter and moisture directly into the burner, leading to incomplete combustion, increased combustion waste, and reduced thermal efficiency. Summary of the Invention

[0003] The purpose of this invention is to address the above-mentioned problems by providing an integrated structure for air filtration and rainwater collection in a gas-fired wall-hung boiler.

[0004] An integrated air filtration and rainwater collection structure for a gas-fired wall-hung boiler includes a boiler shell, a boiler body inside the boiler shell, a coaxial flue connected to the top of the boiler shell, the coaxial flue connected to the boiler body, and an air filtration and rainwater collection structure fixed on the inner wall of the top of the boiler shell, the position of the air filtration and rainwater collection structure corresponding to the coaxial flue.

Detailed Implementation

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0021] like Figure 1 and Figure 2 As shown, an integrated air filtration and rainwater collection structure for a gas-fired wall-hung boiler includes a boiler shell 1, a boiler body 2 inside the boiler shell 1, a coaxial flue 3 connected to the top of the boiler shell 1, the coaxial flue 3 connected to the boiler body 2, and an air filtration and rainwater collection structure 4 fixed on the inner wall of the top of the boiler shell 1, the position of the air filtration and rainwater collection structure 4 corresponding to the coaxial flue 3.

[0022] The coaxial flue 3 is connected to the main body 2 of the wall-hung boiler and is used for the exhaust of combustion gases. At the same time, it is also used for the intake of fresh air to provide air for the combustion furnace. The coaxial flue 3 is set slightly upward. In rainy weather, some rainwater or condensate enters the interior of the wall-hung boiler shell 1 along the coaxial flue 3. The rainwater or condensate contains dust and particulate matter. After being filtered by the air filter and rainwater collection structure 4, the particulate matter is purified by the air filter and rainwater collection structure 4. The air enters the main body 2 of the combustion furnace, and the liquid is discharged outside the wall-hung boiler shell 1.

[0023] like Figure 2 As shown, the coaxial flue 3 includes an inner pipe 5 and an outer pipe 6, which are coaxially arranged with the outer pipe 6 sleeved outside the inner pipe 5. The inner pipe 5 connects to the main body 2 of the wall-hung boiler, and the outer pipe 6 connects to the air filter and rainwater collection structure 4. The inner pipe is used to discharge the exhaust gas after combustion in the main body 2 of the wall-hung boiler, and the jacket between the inner pipe 5 and the outer pipe 6 is used to allow fresh air to enter the outer shell 1 of the wall-hung boiler.

[0024] In this embodiment, as Figure 3 As shown, the air filtration and rainwater collection structure 4 includes a support bracket 7 and a filter assembly 8. The edge of the support bracket 7 is in close contact with the inner wall of the wall-hung boiler shell 1. The filter assembly 8 is fixed on the support bracket 7. The inner tube 5 is inserted into the support bracket 7 to connect with the wall-hung boiler body 2.

[0025] like Figure 3 and Figure 4 As shown, the support bracket 7 is provided with an inner tube bayonet 9, into which the inner tube 5 is inserted. The shape and size of the inner tube bayonet 9 are adapted to the inner tube 5. In a preferred embodiment, the inner tube bayonet 9 is located in the middle of the support bracket 7, and there are two filter screen assemblies 8 located on both sides of the inner tube bayonet 9.

[0026] The filter assembly 8 includes a filter screen 10, with a support mesh plate 11 on each of the upper and lower surfaces of the filter screen 10. The support mesh plate 11 is fixedly connected to the support bracket 7. The support mesh plate 11 is mesh-shaped and acts as a skeleton to support the filter screen 10, preventing deformation of the filter screen 10. The support mesh plate 11 can be fixed to the support bracket 7 with screws or with clips.

[0027] Those skilled in the art should know that although the material of the filter screen 10 used in this application is PU, it is not limited to the material of the filter screen being PU. It can also be asbestos cloth, wire mesh, ceramic, sponge, etc.

[0028] A baffle 12 is provided on each side of the inner pipe bayonet 9, and a water collection trough 13 is formed between the two baffles 12. A drain outlet 14 is provided in the water collection trough 13, and the outer pipe 6 is positioned corresponding to the water collection trough 13.

[0029] The projection of the connection between the outer pipe 6 and the outer shell 1 of the wall-mounted boiler falls into the water collection tank 13. Here, projection means that the entire opening of the outer pipe 6 falls into the water collection tank 13. It can be understood that the water collection tank 13 is larger than the outer pipe 6 at this point and completely covers the outer pipe 6, so that the liquid dripping from the opening of the outer pipe 6 can fall into the water collection tank 13.

[0030] This embodiment also provides a gas-fired wall-hung boiler with the above-described integrated structure for air filtration and rainwater collection.

[0031] The working principle of this invention is: combining Figure 2 As shown, fresh air carrying water droplets, rainwater, or particulate matter enters from the jacket between the inner pipe 5 and the outer pipe 6 into the space between the wall-mounted boiler shell 1 and the support bracket 7. Liquid and some particulate matter fall into the water collection tank 13 and are discharged outdoors through the drain pipe 14a connected to the drain outlet 14.

[0032] After the air passes through the filter screens 10 on both sides of the water collection tank 13, the particulate matter is blocked by the filter screens 10, thereby purifying the air. The purified air enters the premixer 100, mixes with the gas coming in from the gas pipeline 101, and then enters the main body 2 of the wall-hung boiler through the fan 102 for combustion.

[0033] In this application, air containing residual dust particles or water vapor is blocked when it passes through the filter, thereby purifying the air. Finally, during combustion, the amount of waste generated during combustion is reduced, protecting the heat exchanger and improving thermal efficiency.

[0034] The specific embodiments described herein are merely illustrative examples of the spirit of the invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of the invention.
