Description

Technical Field

[0001] This utility model belongs to the field of combustion pool technology, and in particular relates to a novel combustion pool. Background Technology

[0002] The use of biomass fuel pits dates back to the long-standing reliance on biomass energy in rural northern China. Northern rural areas have abundant resources of straw and firewood, making biomass fuel pits virtually free. Furthermore, no complex equipment is required, allowing farmers to build and maintain them themselves.

[0003] In the absence of centralized heating and modern energy infrastructure, the problems faced by combustion pools have gradually become apparent. Fuel accumulates in the combustion pool, resulting in incomplete combustion, wasting energy, and affecting thermal efficiency; insufficient oxygen supply leads to fuel self-extinguishing, interrupting combustion and reducing combustion stability; and the waste heat from flue gas is not effectively recovered and is directly emitted, wasting energy and carrying pollutants, causing pollution.

[0004] Therefore, the transformation and improvement of combustion pools are of great significance. Utility Model Content

[0008] The filtration module is connected to the top of the heat exchange module and is used to filter the flue gas after heat exchange and discharge it from the heat exchange module.

[0009] The heat exchange module includes a combustion chamber flue connected to the combustion module. The combustion chamber flue is a combined flue system that uses the flue gas generated by the combustion of the combustion module to heat the entire house. The flue design and arrangement are based on the house type, and the route of the combustion chamber flue heats the rooms through the heat radiation of the flue gas. Heat exchange tubes are installed in the combustion chamber flue, and the heat exchange tubes adopt a structure of several U-shaped pipes connected end to end to make the flue gas easier to accumulate. The two ends of the heat exchange tubes are connected to the water injection tank and the water outlet tank, respectively. A thermometer is also installed on the heat exchange tubes to monitor the temperature inside the heat exchange tubes. A detachable and movable smoke plate is also installed at the end of the combustion chamber flue near the filter module.

[0010] A further technical solution is that one side of the combustion chamber flue is provided with transparent tempered glass.

[0011] In a further technical solution, the movable smoke plate is connected to the inside of the combustion chamber flue using a snap-fit ​​connection method.

[0012] A further technical solution is provided, wherein the combustion module is provided with a movable feed port, the combustion module is provided with a furnace shield, a number of fire tongs are provided below the furnace shield and the fire tongs are connected to the furnace shield, and the bottom of the combustion module is also provided with a bottom pull plate.

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0023] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0024] like Figure 1-5 As shown, a novel combustion tank provided in one embodiment of the present invention includes a heat exchange module 1, a combustion module 2, and a filter module 3;

[0025] The combustion module 2 is connected to the bottom of the heat exchange module 1, and generates flue gas through smoldering combustion, and then delivers the flue gas to the heat exchange module 1;

[0026] The filter module 3 is connected to the top of the heat exchange module 1 and is used to filter the flue gas after heat exchange and discharge it from the heat exchange module 1.

[0027] The heat exchange module 1 includes a combustion flue 101 connected to the combustion module 2. The combustion flue 101 is a combined flue designed to heat the entire house using the flue gas generated by the combustion of the combustion module 2. The combustion flue 101 heats the entire house using the flue gas generated by the smoldering combustion of the combustion module 2. The flue design and arrangement are based on the house type. The route of the combustion flue 101 heats the rooms through the heat radiation of the flue gas. A heat exchange tube 104 is installed in the combustion flue 101. The heat exchange tube 104 adopts a structure of several U-shaped pipes connected end to end, making it easier for the flue gas to accumulate. The two ends of the heat exchange tube 104 are connected to the water injection tank 102 and the water outlet tank 103, respectively. A thermometer 105 is also installed on the heat exchange tube 104 for monitoring the temperature inside the heat exchange tube 104. A detachable and movable smoke plate 106 is also provided at the end of the combustion flue 101 near the filter module 3.

[0028] In this embodiment of the invention, during use, flue gas is generated by the smoldering combustion of the combustion module 2. This flue gas is then transported to the combustion chamber flue 101, and the route traversed by the flue gas provides heating to the room through thermal radiation. Simultaneously, the flue gas can exchange heat with the heat exchange tubes 104. Water is continuously injected into the heat exchange tubes 104 through the water tank 102, and after heat exchange, it is transported to the outlet water tank 103 for collection, thus utilizing the waste heat of the flue gas. The water temperature in the heat exchange tubes 104 can be monitored by the thermometer 105, and once the specified temperature is reached, it is discharged into the outlet water tank 103 to meet usage requirements. Furthermore, by changing the relative position of the movable smoke plate 106, the flue gas flow rate can be adjusted. This allows the flue gas in the combustion chamber flue 101 to accumulate, promoting better heat exchange with the water in the heat exchange tubes 104, while simultaneously enabling the filter module 3 to effectively and promptly discharge the cooled flue gas from the combustion chamber flue 101 to the outside.

[0029] In a preferred embodiment of the present invention, a transparent tempered glass is provided on one side of the combustion flue 101, making it easy to observe the accumulation state of the flue gas in the combustion flue 101.

[0031] like Figure 3 As shown, in a preferred embodiment of the present invention, the combustion module 2 is provided with a movable feed inlet 201, the combustion module 2 is provided with a furnace shield 202 inside, a plurality of fire tongs 203 are provided below the furnace shield 202 and the fire tongs 203 are connected to the furnace shield 202, and the bottom of the combustion module 2 is also provided with a bottom pull plate 204.

[0032] In this embodiment of the invention, the feed inlet 201 adopts a drawer-type structure and is connected to the body of the combustion module 2 by a snap-fit, making it easy to fill with biomass fuel and ensuring uniform fuel distribution to prevent accumulation. The fire tongs 203 can move the furnace cover 202 up and down, thereby promoting contact between the combustible biomass fuel and oxygen components on the furnace cover 202 and ensuring timely separation of the biomass waste from the furnace cover 202 after combustion. The bottom drawer 204 can collect the biomass waste separated from the furnace cover 202, facilitating cleaning.

[0033] like Figure 4 As shown, in a preferred embodiment of this utility model, the fire tongs rod 203 adopts a three-section electro-hydraulic rod design with different thicknesses (thickness comparison ①>③>②). Through the up-and-down reciprocating motion of the fire tongs rod 203, the contact between combustible biomass fuel and oxygen components is promoted, and the biomass waste after combustion is separated from the furnace in a timely manner.

[0034] like Figure 5 As shown, in a preferred embodiment of this utility model, the filter module 3 includes a filter box 302 and an exhaust fan 301 installed on the top of the combustion flue 101. The exhaust fan 301 effectively regulates the accumulation of flue gas in the combustion flue 101 and exhausts it outdoors. The filter box 302 filters the flue gas.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
