Description

Technical Field

[0001] The utility model relates to a multifunctional fuel-fired air heater for recycling tail gas. Background Art

[0002] Fuel-fired air heaters can be used in animal husbandry, vegetable and fruit greenhouses, etc. Fuel-fired air heaters are generally composed of a combustion chamber and a motor fan. The motor drives the fan to transfer the heat energy from the combustion chamber to the external space that needs to be heated. However, the air outlets of the combustion chambers of fuel-fired air heaters currently on the market are not sealed structures, resulting in the exhaust gas generated after the fuel is burned being directly discharged into the heated space, causing certain pollution to the air; and the fuel of the fuel-fired air heaters currently on the market cannot be heated, resulting in poor fuel combustion and insufficient combustion; or the heating of the fuel requires heating elements (such as electric heating tubes, etc.) that require additional power supply, wasting energy.

[0018] The combustion head 5 includes a wind wheel 51, a second fan 52 and an air outlet 53 from right to left. The wind wheel 51 and the second fan 52 are connected by a channel. An air inlet 511 is arranged on the side of the wind wheel 51. The second fan 52 is connected to a motor. The air outlet 53 radiates from the inside to the outside. An ignition needle and a fuel nozzle are arranged between the air outlet 53 and the second fan 52.

[0019] The combustion chamber 6 includes an opening 61, a second chamber 62, a connecting channel 63, a third chamber 64 and a fourth chamber 65; the second chamber 62 is inside the opening 61, the second fan 52 and the air outlet 53 are both arranged in the second chamber 62, the opening 61 is sealed and connected to the combustion head 5, the second chamber 62 is a completely sealed space, the fuel from the fuel outlet is ignited by the ignition needle, and the second fan 52 blows the flame into the second chamber 62 for combustion; the connecting channel 63 is arranged at the bottom of the second chamber 62, the connecting channel 63 connects the second chamber 62 and the fourth chamber 65, the bottom of the fourth chamber 65 is connected with a smoke exhaust pipe 7, the smoke exhaust pipe 7 passes through the fuel inside the fuel tank 2, and then is connected to the bottom of the wind wheel 52 and welded and fixed, the gas in the smoke exhaust pipe 7 can pass through the combustion head 5 and then enter the combustion chamber 6.

[0022] The multifunctional fuel heater for exhaust gas recycling of the utility model sets the combustion chamber 6 as a sealed chamber, and discharges the hot exhaust gas after combustion into the exhaust pipe 7 by connecting the second chamber 62 and the fourth chamber 64. The exhaust pipe 7 is connected to the wind wheel 51, and the wind wheel 51 rotates rapidly to send the hot exhaust gas into the second chamber 62. At the same time, fresh air from the outside is sucked in through the air inlet 511 and sent into the second chamber 62, so that the hot exhaust gas can be fully burned, saving resources and protecting the environment; the fuel passes through the fuel tank 2 through the exhaust pipe 7, so that the hot exhaust gas heats the fuel when passing through the exhaust pipe 7, so that the fuel can be burned more fully and energy is saved.
