Description

Technical Field

[0001] The utility model relates to the technical field of heating equipment, and more specifically, to an energy-saving and environment-friendly heating equipment. Background Art

[0002] In the current process of social development, energy shortage and environmental deterioration have become major challenges facing the world. Traditional heating methods mainly rely on fossil energy such as coal, oil, and natural gas. On the one hand, these energy sources are non-renewable resources, their reserves are decreasing, and supply pressure is increasing. On the other hand, traditional heating equipment will produce a large amount of waste gas and pollutants in the process of burning fossil energy, such as carbon dioxide, sulfur dioxide, nitrogen oxides, etc., which cause serious pollution to the atmospheric environment.

[0003] After searching, the Chinese patent with announcement number CN217887343U discloses a high-efficiency, energy-saving and environmentally friendly boiler heating equipment. The exhaust gas generated by the boiler in the cited device is directly discharged to the outside without being treated, which will cause pollution to the environment and needs to be improved. By setting a treatment box, an exhaust pipe, a filter plate, an activated carbon filter, an exhaust pipe and a cleaning mechanism, the filter plate can be cleaned by the cleaning mechanism before using the boiler body, which reduces the occurrence of smoke and dust clogging the filter plate and improves the exhaust gas treatment efficiency. The exhaust gas generated by the boiler body is discharged into the interior of the treatment box through the exhaust pipe. The filter plate can filter the smoke and dust in the exhaust gas, and the activated carbon filter can adsorb the irritating odor in the exhaust gas. The treated exhaust gas is discharged to the outside of the treatment box through the exhaust pipe, thereby having the advantage of efficient exhaust gas treatment and convenient use.

[0004] During the use of the boiler heating equipment, although the exhaust gas is treated, a large amount of heat energy is wasted during the exhaust gas discharge process, which increases energy consumption costs, reduces energy utilization efficiency, and the heat in the exhaust gas is not effectively utilized.

A heat exchange pipe 5 is installed inside the exhaust gas treatment box 4. One end of the heat exchange pipe 5 is fixedly connected to a water inlet pipe 6, and the other end of the heat exchange pipe 5 is fixedly connected to a drain pipe 7. The top and bottom of the inner wall of the exhaust gas treatment box 4 are fixedly connected to a baffle 8. An exhaust pump 9 is fixedly installed on the front side of the exhaust gas treatment box 4. One end of the exhaust pump 9 is fixedly connected to a first circulating air pipe 10, and the other end of the exhaust pump 9 is fixedly connected to a second circulating air pipe 11.

[0027] As attached Figure 1 、 2 As shown in Figures 5 and 6, one end of the exhaust gas exhaust pipe 3 passes through the exhaust gas treatment box 4 and extends to the inside of the exhaust gas treatment box 4. A first valve 12 is fixedly installed inside the exhaust gas exhaust pipe 3. An exhaust pipe 13 is fixedly connected to one side of the exhaust gas treatment box 4. A second valve 14 is fixedly installed inside the exhaust pipe 13 to facilitate sealing of the exhaust gas treatment box 4, thereby facilitating exhaust gas circulation and heat exchange.

[0028] As attached Figure 1-5 As shown, the tops of the water inlet pipe 6 and the drain pipe 7 both pass through the exhaust gas treatment box 4 and extend to the top of the exhaust gas treatment box 4. One end of the first circulating air pipe 10 and the second circulating air pipe 11 both pass through the exhaust gas treatment box 4 and extend to the inside of the exhaust gas treatment box 4.

[0032] Working principle of the utility model: The energy-saving and environmentally friendly heating equipment provided by the utility model is used. During use, the energy-saving and environmentally friendly heating equipment mainly generates heat for heating through the heating boiler 1, and at the same time uses the exhaust gas heat exchange mechanism to recover the heat in the exhaust gas to improve energy utilization efficiency. Water enters the heating boiler 1 through the boiler water inlet pipe 2, and is heated in the heating boiler 1 to generate hot water or steam, which is used to provide heat to the heating system. The high-temperature exhaust gas generated during the operation of the heating boiler 1 is discharged through the exhaust gas exhaust pipe 3. The first valve 12 inside the exhaust gas exhaust pipe 3 can control the exhaust gas discharge flow rate. The high-temperature exhaust gas enters the exhaust gas treatment box 4 from the exhaust gas exhaust pipe 3 and passes through the inner wall of the exhaust gas treatment box 4. A plurality of baffles 8 are fixedly connected to the top and bottom and arranged in an upper and lower staggered manner. When the high-temperature exhaust gas enters the exhaust gas treatment box 4, the baffles 8 slow down the flow rate of the high-temperature exhaust gas, so that the exhaust gas stays in the exhaust gas treatment box 4 for a longer time, which is convenient for the heat exchange tube 5 to fully absorb the heat in the exhaust gas. Low-temperature water enters the heat exchange tube 5 from the water inlet pipe 6 and exchanges heat with the high-temperature exhaust gas in the aluminum alloy heat exchange tube 5. The heated water is discharged from the drain pipe 7 and can be reused or enter other heating links to achieve heat recovery. The exhaust pump 9 circulates the exhaust gas in the exhaust gas treatment box 4 through the first circulation air pipe 10 and the second circulation air pipe 11 to ensure that the exhaust gas can fully contact the heat exchange tube 5, thereby improving the heat recovery efficiency.

[0033] A filter screen 15 is fixedly installed on the inner wall of the exhaust gas treatment box 4 away from the heat exchange tube 5, which can filter impurities in the exhaust gas and reduce pollution to the environment. An exhaust pipe 13 is fixedly connected to one side of the exhaust gas treatment box 4, and a second valve 14 is fixedly installed inside the exhaust pipe 13 to control the discharge of treated exhaust gas. When the exhaust gas needs to be discharged, the second valve 14 is opened and the exhaust gas is discharged from the exhaust pipe 13. A pressure relief pipe 16 is fixedly connected to the front side of the exhaust gas treatment box 4, and a third valve 17 is fixedly installed inside the pressure relief pipe 16. When the pressure in the exhaust gas treatment box 4 is too high or a fault occurs, the third valve 17 can be opened to discharge the exhaust gas urgently through the pressure relief pipe 16.
