[0002] A regenerative combustion furnace is a device that stores the heat in the furnace. Compared with traditional combustion furnaces, regenerative combustion furnaces have significant energy-saving and environmental protection effects. Regenerative combustion technology is a technology that burns under high-temperature and low-oxygen air conditions, also known as high-temperature air combustion technology. Regenerative combustion technology fundamentally improves the energy utilization rate of the heating furnace. In the process of industrial waste gas treatment, regenerative combustion furnaces are needed to treat the waste gas.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figures 1-4 The utility model discloses a heat storage type combustion furnace device, which includes a furnace body 1, the outer surface of the furnace body 1 is a cylindrical structure, a rectangular box 2 is fixedly installed on the lower inner wall of the furnace body 1, and an air distribution mechanism 3 is fixedly installed on the upper side wall of the rectangular box 2. An air intake pipe 4 is fixedly installed on the left side wall of the rectangular box 2, and the left end of the air intake pipe 4 is inserted into the left side of the left wall of the furnace body 1. A heat storage component 5 is arranged in the furnace body 1 on the upper side of the air distribution mechanism 3, and a combustion component 6 is arranged in the middle position of the upper side wall of the furnace body 1. An exhaust pipe 7 is fixedly installed on the left side of the upper surface of the furnace body 1, and a connecting pipe 8 is fixedly installed on the right side of the exhaust pipe 7, and the connecting pipe 8 is connected to the heat exchange mechanism 9. The heat exchange mechanism 9 is fixedly sleeved on the outer surface of the furnace body 1, and an exhaust pipe 10 is arranged on the left side of the heat exchange mechanism 9. An exhaust mechanism 11 is arranged on the exhaust pipe 7 near the lower side.

[0023] Specifically, the air distribution mechanism 3 includes a transmission rod 301, a mechanical seal 302, a turbine blade 303, an air distribution pipe 304 and an air outlet 305. The transmission rod 301 is installed on the upper side wall of the rectangular box 2 through the mechanical seal 302. The turbine blade 303 is provided on the transmission rod 301 at a position corresponding to the air inlet pipe 4. Four air distribution pipes 304 are evenly arranged around the outer surface of the transmission rod 301 near the upper side, and air outlets are evenly opened on the side walls of the air distribution pipe 304.

[0024] In this embodiment, the high-temperature exhaust gas flowing into the air inlet pipe 4 drives the turbine blades 303 to rotate, so that the turbine blades 303 drive the transmission rod 301 to rotate in the mechanical seal 302, thereby causing the transmission rod 301 to drive the air distribution pipe 304 to rotate. The high-temperature exhaust gas in the rectangular box 2 flows into the transmission rod 301 through the lower surface of the transmission rod 301, and then flows into the air distribution pipe 304 through the transmission rod 301. The high-temperature exhaust gas in the air distribution pipe 304 is evenly distributed in the furnace body 1 through the air outlet 305.

[0025] Specifically, the transmission rod 301 is a hollow structure with an open lower surface.

[0026] In this embodiment, the transmission rod 301 allows high-temperature exhaust gas to flow into the interior through the lower surface thereof.

[0027] Specifically, the heat exchange mechanism 9 includes a heat exchange tube 901, a water jacket 902, a water inlet pipe 903 and a water outlet pipe 904. The heat exchange tube 901 is wound around the outer surface of the furnace body 1. The water jacket 902 is fixedly installed on the outer surface of the furnace body 1 corresponding to the heat exchange tube 901. The water inlet pipe 903 is installed on the upper side of the left wall of the water jacket 902, and the water outlet pipe 904 is installed on the lower side of the right wall of the water jacket 902.

[0028] In this embodiment, the connecting pipe 8 allows the exhaust gas in the smoke exhaust pipe 7 to flow into the heat exchange pipe 901, and the heat exchange pipe 901 exchanges heat with the water in the water jacket 902, thereby cooling the exhaust gas. The cooled exhaust gas is discharged through the exhaust pipe 10, and the water inlet pipe 903 allows water to flow between the water jacket 902 and the outer surface of the furnace body 1. The water outlet pipe 904 is used to discharge the hot water after heat exchange.

[0029] Specifically, a heat preservation plate 12 is fixedly mounted on the inner wall of the water jacket 902 .

[0030] In this embodiment, the insulation board 12 improves the insulation function of the water jacket 902 .

[0031] Specifically, the exhaust mechanism 11 includes a plug 111, a spring 112, a block 113 and an exhaust hole 114. The plug 111 is threadedly installed on the upper surface of the cylinder, the spring 112 is fixedly installed on the lower surface of the plug 111, the block 113 is fixedly installed on the lower surface of the spring 112, and the block 113 is in contact with the inner wall of the cylinder. Exhaust holes 114 are provided on the left and right side walls of the cylinder above the block 113.

[0032] In this embodiment, when the heat exchange mechanism 9 does not vent smoothly, the air pressure in the smoke exhaust pipe 7 will increase. The high air pressure will push the block 113 upward, compressing the spring 112. The lower surface of the block 113 is higher than the exhaust hole 114, allowing the smoke to be discharged through the exhaust hole 114, ensuring that the air pressure in the furnace body 1 is not too high. When the air pressure in the furnace body 1 is normal, the spring 112 pushes the block 113 to move downward to seal the exhaust hole 114.

[0033] When in use, the air intake pipe 4 is connected to the external high-temperature exhaust pipe, and the high-temperature exhaust gas flows into the rectangular box 2 through the air intake pipe 4. The high-temperature exhaust gas flowing into the rectangular box 2 through the air intake pipe 4 drives the turbine blades 303 in the air distribution mechanism 3 to rotate, so that the turbine blades 303 drive the transmission rod 301 to rotate in the mechanical seal 302, thereby causing the transmission rod 301 to drive the air distribution pipe 304 to rotate, and the high-temperature exhaust gas in the rectangular box 2 flows into the transmission rod 301 through the lower surface of the transmission rod 301, and then flows through the transmission rod 301. The high-temperature exhaust gas in the exhaust pipe 304 is evenly distributed in the furnace body 1 through the exhaust hole 305, which can evenly heat the heat storage component 5, store heat evenly, and improve the heat storage efficiency. The heat storage component 5 stores heat, and the combustion component 6 burns the exhaust gas. After combustion, the high-temperature flue gas flows into the exhaust pipe 7, flows into the connecting pipe 8 through the exhaust pipe 7, and flows into the heat exchange pipe 901 in the heat exchange mechanism 9 through the connecting pipe 8. The high-temperature flue gas in the heat exchange pipe 901 exchanges heat with the water in the water jacket 902. The exhaust gas is cooled and discharged through the exhaust pipe 10. The water inlet pipe 903 allows water to flow between the water jacket 902 and the outer surface of the furnace body 1. The water outlet pipe 904 is used to discharge the hot water after heat exchange. The hot water in the water jacket 902 is used. The heat exchange mechanism 9 keeps the furnace body 1 warm to reduce heat loss. At the same time, the outer surface of the water jacket 902 is lower in temperature than the outer surface of the furnace body 1, making the working environment more moderate and avoiding accidental damage caused by high temperature outside the furnace body 1, making it safer and more environmentally friendly to use. When the heat exchange mechanism 9 does not exhaust smoothly, the air pressure in the exhaust pipe 7 will increase. The high air pressure will push the block 113 in the exhaust mechanism 11 upward, compressing the spring 112. The lower surface of the block 113 is higher than the exhaust hole 114, so that the smoke is discharged through the exhaust hole 114, ensuring that the air pressure in the furnace body 1 is too high. When the air pressure in the furnace body 1 is normal, the spring 112 pushes the block 113 to move downward to seal the exhaust hole 114, so that the exhaust gas in the furnace body 1 can be discharged, ensuring that the air pressure in the furnace body 1 is normal and safe to use.

[0034] To sum up, the heat storage combustion furnace device allows the incoming high-temperature exhaust gas to be evenly distributed in the furnace body 1, can evenly heat the heat storage component 5, improve the heat storage efficiency, while increasing the heat exchange utilization function of the high-temperature exhaust gas, and improve the thermal insulation performance of the furnace body 1, avoiding accidental collision damage caused by the high temperature outside the furnace body 1, and is safer and more environmentally friendly to use.
