Therefore, organic waste gas treatment equipment is needed to purify the gas.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the utility model with reference to the accompanying drawings in the embodiments of the utility model.

[0021] The utility model provides a technical solution: As Figures 1 to 5As shown in the figure, in this embodiment, an RTO regenerative organic waste gas treatment device with high waste heat utilization efficiency includes an RTO burner 1. A support base 2 is fixedly installed at the bottom of the RTO burner 1. An air inlet end 12 and an air outlet end 13 are respectively arranged at the bottom ends of both ends of the RTO burner 1. The air inlet end 12 is connected to an air inlet pipe 3, and the air outlet end 13 is communicated with an air outlet pipe 4. A waste heat utilization mechanism is arranged between the air inlet pipe 3 and the air outlet pipe 4. The waste heat utilization mechanism is composed of an outer pipe 5, an input pipe 6, a heat exchange pipe 7, and an output pipe 14. The end of the air outlet pipe 4 is communicated with the heat exchange pipe 7, the end of the heat exchange pipe 7 is communicated with the output pipe 14, the outer surface of the heat exchange pipe 7 is sleeved with the outer pipe 5, and an input pipe 6 is communicated with the outer wall of the outer pipe 5 near the air outlet pipe 4. The end of the outer pipe 5 near the air inlet pipe 3 is communicated with the air inlet pipe 3.

[0022] Among them, the diameters of the air inlet pipe 3, the air outlet pipe 4, the input pipe 6, the heat exchange pipe 7, and the output pipe 14 are the same. The radius of the outer pipe 5 is equal to the radius of the heat exchange pipe 7 multiplied by the square root of two. The gap between the outer pipe 5 and the heat exchange pipe 7 forms a heat exchange air channel.

[0023] With such a setting, it can be ensured that the cross-sectional area of the heat exchange air channel is equal to the cross-sectional area of the heat exchange pipe 7, so as to ensure that the gas flow area of the heat exchange air channel is the same as the flow areas of the air inlet pipe 3 and the input pipe 6, and further ensure the stability of gas flow.

[0024] Among them, both the heat exchange pipe 7 and the outer pipe 5 are distributed in a serpentine line shape.

[0025] With such a setting, the length of the heat exchange pipe 7 can be increased within a limited space, so that the heat exchange time of the waste gas is longer.

[0026] Among them, the heat exchange pipe 7 is made of ceramic material. With such a setting, the heat exchange pipe 7 can quickly conduct the heat in the waste gas after combustion to the unburned waste gas.

[0027] Among them, fixing sleeves 8 are sleeved on the vertical sections of the outer pipe 5. Multiple fixing sleeves 8 are fixedly connected through a connecting plate 9. A support frame 10 is fixedly connected to the side wall of the connecting plate 9. A plurality of fixing holes 11 are opened at the bottom of the support frame 10.

[0028] Through the arranged fixing sleeves 8, connecting plate 9, and support frame 10, a supporting effect can be achieved on the outer pipe 5 to ensure the stability of the outer pipe 5. The support frame 10 can be fixed to the ground through the cooperation of an external bolt and the fixing holes 11.

[0029] The present utility model provides an RTO regenerative organic waste gas treatment device with high waste heat utilization efficiency. The specific working principle is as follows:

[0030] During use, the unburned waste gas is introduced through the input pipe 6 between the outer pipe 5 and the heat exchange pipe 7. The waste gas will enter the RTO burner 1 through the intake pipe 3 at the other end of the outer pipe 5. The waste gas after combustion will enter the heat exchange pipe 7 through the outlet pipe 4. The heat exchange pipe 7 can quickly conduct the heat in the waste gas after combustion to the unburned waste gas, thereby preheating the unburned waste gas. This can not only improve the combustion efficiency of the waste gas but also avoid heat damage. The heat exchange pipe 7 and the outer pipe 5 distributed in a serpentine shape can increase the length of the heat exchange pipe 7 within a limited space, resulting in a longer heat exchange time for the waste gas and a better preheating effect.

[0031] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
