[0002] The development of economy and society and the demand of industrialization have made catalytic technology, especially catalytic combustion technology, increasingly become an indispensable industrial technology. With the improvement of people's living standards and the growth of demand, the catalytic industry will continue to enter thousands of households and people's lives. Catalytic combustion plays an extremely important role in improving the combustion process, reducing the reaction temperature, promoting complete combustion, and inhibiting the formation of toxic and harmful substances. It has been widely used in many aspects of industrial production and daily life.

[0003] At present, after catalytic combustion of toxic gases, the gases are usually discharged after dust removal through a dust collector.

For this reason, we have proposed a catalytic combustion exhaust gas treatment device to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Example 1

[0023] Reference Figure 1 , 4 A protective box 9 is installed through the lower end of the first discharge pipe 1, and a coil 16 is arranged in the protective box 9, and the coil 16 is wound around the side wall of the first discharge pipe 1 in the protective box 9. A refrigeration box 13 is arranged on one side of the first discharge pipe 1, and the coil 16 is connected to the refrigeration box 13 through a return pipe 10. A refrigeration device is arranged at the bottom of the refrigeration box 13 for refrigerating the coolant to keep it at a corresponding temperature. An infusion tube 12 is connected to one side of the upper end of the coil 16, and one end of the infusion tube 12 passes through the side wall of the protective box 9 and is connected to one side of the lower end of the refrigeration box 13. Openings are arranged at both upper and lower ends of the protective box 9, and the first discharge pipe 1 passes through the two openings, and a sealing gasket 5 is installed on a side wall around the opening, and a circle of the sealing gasket 5 contacts the side wall of the first discharge pipe 1. A second discharge pipe 7 is installed on one side of the lower end of the protective box 9, and a valve is installed on the second discharge pipe 7, and an electromagnetic valve 11 is installed on the return pipe 10.

[0024] This embodiment can keep the temperature in the protection box 9 constant, and can continuously and uninterruptedly cool the gas after catalytic combustion.

[0025] Example 2

[0026] Reference Figure 3 A cold air device 8 is provided on the other side of the first discharge pipe 1. The cold air device 8 adopts a 1.1KW main motor. The cold air device 8 is connected to a cold air delivery pipe 2. A partition 15 is provided on the top of the first discharge pipe 1, and the partition 15 is spirally arranged. The spiral arrangement can not only increase the distance traveled by the gas, but also enhance the effect of cold air mixing.

[0027] One end of the cold air delivery pipe 2 passes through the side wall of the first discharge pipe 1 and extends into the partition 15. The lower end of the first discharge pipe 1 is connected to the air delivery pipe 6. The upper end of the first discharge pipe 1 is installed with a mounting frame 3. The upper end of the cold air delivery pipe 2 is installed on the mounting frame 3. A flap valve 4 is installed on the cold air delivery pipe 2. The flap valve 4 is controlled as needed to adjust the amount of cold air delivery.

[0028] This embodiment can use quantitatively adjusted cold air to cool the treated gas, and can also be combined with embodiment 1 to cool the gas to improve the cooling effect. Different cooling forms can be selected according to different usage requirements.

[0029] In the utility model, when it is necessary to treat the exhaust gas from catalytic combustion, the exhaust gas after catalytic combustion is sent into the air pipe 6 after dust removal, and then the air pipe 6 sends the exhaust gas into the first discharge pipe 1. When the exhaust gas passes through a section in the protection box 9, the exhaust gas is quickly cooled down due to the cooling liquid in the coil 16. When the exhaust gas reaches the arc-shaped partition 15, the cold air device 8 sends the cold air into the partition 15 through the cold air delivery pipe 2, and the treated gas that has been cooled once is cooled down for the second time. At the same time, the arc-shaped setting makes it cool down quickly again, and then it is discharged through the discharge port at the upper end.

Any technician familiar with the technical field within the technical scope disclosed by the utility model, who makes equivalent replacements or changes based on the technical scheme and utility model concept of the utility model, should be covered by the protection scope of the utility model.
