Description

Technical Field

[0001] The utility model relates to the technical field of heat energy recycling, in particular to a tail gas heat energy recycling device of gas heating equipment. Background Art

[0002] Gas is a general term for gaseous fuels, which can burn and release heat for use by residents and industrial enterprises. There are many types of gas, mainly natural gas, artificial gas, liquefied petroleum gas, biogas, and coal-to-gas. Gas boilers are used to burn natural gas or artificial gas, liquefied gas and other energy materials, and use chemical energy to burn and generate heat to heat hot water, which is then transported to the end of the room and refluxed to the gas boiler for circulation heating after heat release. The heating water temperature can reach up to 85°C.

[0003] A large amount of tail gas will be generated in the process of gas heating, and these tail gases still contain a lot of residual heat. If these tail gases are discharged directly, it will inevitably cause unnecessary waste. Therefore, a tail gas heat energy recycling device for gas heating equipment is proposed. Utility Model Content

[0004] The purpose of the utility model is to provide a device for recycling the exhaust heat energy of gas heating equipment, which solves the problem that the gas heating process group will generate a large amount of exhaust gas, and the exhaust gas will have a lot of residual heat, and direct discharge will cause waste.

[0005] The utility model is implemented as follows: an exhaust gas heat energy recycling device for gas heating equipment comprises a workbench, on which an air pump, a water storage tank, a heating tank and a water pump are arranged; an air inlet pipe and an air supply pipe are arranged on the air pump, the heating tank is connected to the air pump via the air supply pipe; a water inlet pipe and a water supply pipe are arranged on the water pump, the heating tank is connected to the water pump via the water supply pipe; an S-shaped water supply pipe is arranged inside the heating tank, one end of the S-shaped water supply pipe is communicated with the water supply pipe, the other end of the S-shaped water supply pipe is placed outside the heating tank, and one end of the S-shaped water supply pipe located outside the heating tank is communicated with the water storage tank.

[0006] A further technical solution of the utility model is that a filter assembly is provided at the top of the heating chamber.

[0007] A further technical solution of the utility model is: the filter assembly includes: a filter bucket arranged on the top of the heating chamber, a vent hole arranged on the bottom surface of the filter bucket, a sealing ring arranged on the edge of the filter bucket, and an activated carbon filter layer arranged on the filter bucket.

[0024] When in use, the air pump 2 delivers the exhaust gas to the heating chamber 4 through the air pipe 22, so that the heating chamber 4 is filled with the exhaust gas to form a heating environment. At this time, the water pump 7 delivers the external water source introduced by the water inlet pipe 71 to the inside of the heating chamber 4 through the water pipe 72. Since the S-shaped water pipe 31 is connected to the water pipe 72, the water is continuously heated during the output process of the S-shaped water pipe 31, and the heated water enters the water storage chamber 3 through the end of the S-shaped water pipe 31 located outside the heating chamber 4.

[0025] Embodiment 2: Figure 2 As shown, a filter assembly 8 is provided at the top of the heating chamber 4. The main function of the filter assembly 8 is to filter the exhaust gas. The unfiltered exhaust gas cannot be directly discharged into the atmosphere.
