Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment, in particular to a recycling combustion heating device. Background Art

[0002] With the rapid development of chemical and other industries, a large amount of toxic and harmful waste gas will be generated in the industrial production process. If the waste gas discharged into the atmosphere fails to meet the national emission standards, these industrial waste gases will have a great impact and harm on human health, crop growth, and weather and climate. The design of the recycling combustion heating device is mainly to purify the waste gas and reduce environmental pollution.

For this reason, we propose a recovery combustion heating device. Utility Model Content

The heat recovery component 200 also includes a fuel gas branch pipe 209 fixedly installed on the upper end of the fuel gas input pipe 201, and an exhaust pipe 210 fixedly installed on the top of the upper combustion chamber 207. The heat recovery component 200 also includes a first water inlet pipe 211 and a first water outlet pipe 212 fixedly installed on the upper and lower ends of the outer side of the lower spiral channel 205, and a second water inlet pipe 213 and a second water outlet pipe 214 fixedly installed on the upper and lower ends of the outer side of the upper spiral channel 208. The heat recovery component 200 also includes a first solenoid valve 215 and a second solenoid valve 216 fixedly installed on the upper ends of the fuel gas input pipe 201 and the exhaust gas input pipe 202, respectively.

[0024] Specifically, the recovery combustion heating device is a device that burns exhaust gas to purify harmful substances in the exhaust gas and reduce environmental pollution. The lower combustion chamber 204 and the upper combustion chamber 207 arranged at the upper and lower ends of the combustion tube 100 can respectively burn and re-burn the input exhaust gas, thereby ensuring the sufficient combustion of harmful substances in the exhaust gas for safe discharge, and the lower spiral channel 205 and the upper spiral channel 208 arranged at the outer ends of the lower combustion chamber 204 and the upper combustion chamber 207 can also recycle the heat energy released during combustion. The symmetrically arranged fuel gas inlet pipe 201 and the exhaust gas inlet pipe 202 can ensure uniform mixing of fuel gas and exhaust gas during combustion. The sealing plate 203 mainly ensures the sealing of the bottom of the lower combustion chamber 204. The gathering hood 206 fixedly installed at the upper end of the lower combustion chamber 204 mainly gathers the exhaust gas after combustion so that it can be re-burned through the fuel gas branch pipe 209 to ensure the adequacy of combustion.

[0025] Embodiment 2:

[0026] Based on the first embodiment, Figure 3 As shown, the auxiliary component 300 includes a lower blocking cover 301 movably installed in the lower combustion chamber 204, and lower fixing rods 302 fixedly installed between the lower combustion chamber 204 and both sides of the lower blocking cover 301. The auxiliary component 300 also includes an upper blocking cover 303 movably installed in the upper combustion chamber 207, and upper fixing rods 304 fixedly installed between the upper combustion chamber 207 and both sides of the upper blocking cover 303.

[0027] Specifically, the lower blocking cover 301 and the upper blocking cover 303 installed in the lower combustion chamber 204 and the upper combustion chamber 207 in the combustion tube 100 can block the sprayed exhaust gas and fuel gas during mixing, thereby ensuring the sufficient combustion of the exhaust gas and the fuel gas in the lower combustion chamber 204 and the upper combustion chamber 207, so as to improve the heating effect of the water flow in the lower spiral channel 205 and the upper spiral channel 208.

[0028] The working principle and use process of this utility model:

[0029] When the fuel gas and exhaust gas in the lower combustion chamber 204 in the combustion tube 100 are burned after being ejected through the fuel gas inlet pipe 201 and the exhaust gas inlet pipe 202, the lower blocking cover 301 on the top will block the ejected fuel gas, so that the fuel gas and exhaust gas can be fully burned in the lower combustion chamber 204, so as to improve the heating effect on the water flow in the outer lower spiral channel 205. The exhaust gas after combustion in the lower combustion chamber 204 enters the gathering cover 206 from the outside of the lower blocking cover 301, and is gathered at the top of the gathering cover 206. It is then mixed and burned with the fuel gas ejected from the fuel gas branch pipe 209, and is blocked by the upper blocking cover 303 on the top again, so as to be fully burned in the upper combustion chamber 207, thereby heating the water flow in the upper spiral channel 208 on the outer side of the upper combustion chamber 207. Finally, after the exhaust gas is fully burned in the lower combustion chamber 204 and the upper combustion chamber 207, it will be discharged through the exhaust pipe 210 on the top.

[0030] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
