Description

Technical Field

[0001] This utility model relates to the field of waste gas catalytic combustion technology, and in particular to a regenerative waste gas catalytic combustion device. Background Technology

[0002] Catalytic combustion of waste gas is a highly efficient, energy-saving, and environmentally friendly technology for volatile organic compounds. Its core principle is that, under the action of a catalyst, organic waste gas undergoes a deep oxidation reaction with oxygen, converting it into harmless carbon dioxide, thereby achieving purified emissions.

[0003] The patent with authorization announcement number CN221146557U discloses a waste gas catalytic combustion device. The device includes a body with an air inlet pipe on one side of its outer surface. Two rectangular blocks have a disc fixedly connected to one side of their outer surfaces. A circular groove is formed on one side of the outer surface of the disc, and dry filter cotton is installed inside the groove. The upper and lower sides of the inner wall of the air inlet pipe are respectively fixedly connected to groove blocks. When using this patent, the exhaust gas delivery pipe is connected to the air inlet pipe. The exhaust gas enters the interior of the device and passes through the dry filter cotton, which filters impurities in the organic waste gas. At the same time, the rubber ring can further seal the connection between the air inlet pipe and the exhaust gas delivery pipe. After the exhaust gas enters the interior of the device, it is heated by the heating rod inside the device to react with precious metals to produce water and carbon dioxide, which are then discharged through the exhaust pipe. However, the above-mentioned existing patent still has some shortcomings in actual use. The above-mentioned existing patent does not have the function of oxygenation and exhaust gas diversion. When the concentration of organic waste gas entering the equipment is high, under the high temperature of the heating rod, the waste gas is prone to flash combustion or even explosion in the pipe or reaction chamber.

[0004] Therefore, there is a need to provide a regenerative catalytic combustion device for waste gas with oxygenation function. Utility Model Content

[0005] In order to overcome the shortcomings of the existing patents mentioned above, which lack the functions of oxygenation and waste gas diversion, and are prone to flash combustion or even explosion in the pipeline or reaction chamber when the concentration of organic waste gas entering the equipment is high under the high temperature of the heating rod, this utility model provides a regenerative waste gas catalytic combustion device with oxygenation function.

[0006] To address the aforementioned problems, this utility model adopts the following technical solution: a regenerative catalytic combustion device for waste gas, comprising a catalytic combustion chamber, a horizontal partition, a vertical partition, a gas guide plate, a waste gas inlet pipe, an igniter, a flow guide pipe, a catalytic module, and an outlet pipe. A horizontal partition is fixedly connected to the catalytic combustion chamber, and a vertical partition is fixedly connected to the horizontal partition. Two gas guide plates are fixedly connected between the horizontal and vertical partitions. A waste gas inlet pipe is connected to the catalytic combustion chamber. An igniter is installed inside the catalytic combustion chamber. Multiple flow guide pipes are connected to the horizontal partition. A catalytic module is installed inside the catalytic combustion chamber. Two outlet pipes are connected to the catalytic combustion chamber. The device also includes a gas guide hood, blowers, a connecting pipe, and a ball valve. The gas guide hood is fixedly connected to the catalytic combustion chamber. Two blowers are installed inside the catalytic combustion chamber. A connecting pipe connects the blowers to the gas guide hood, and a ball valve is installed on the connecting pipe.

[0007] Preferably, the catalytic combustion chamber also includes a sliding frame and a filter element, with the sliding frame being slidably installed inside the catalytic combustion chamber and the filter element being installed inside the sliding frame.

[0008] Preferably, the system also includes guide rods, cylinders, and scrapers. Two cylinders are installed on the catalytic combustion chamber, and scrapers are fixedly connected to the telescopic rods of the cylinders. Multiple guide rods are fixedly connected to the transverse partition.

[0009] Preferably, a filter screen is also included, with the filter screen installed on the air guide plate.

[0010] Preferably, it also includes a handle, with the handle fixedly connected to the sliding frame.

[0011] Preferably, it also includes supporting angle irons, with two supporting angle irons installed on the catalytic combustion chamber, and two oblong holes opened on the supporting angle irons.

[0012] Compared with the prior art, the present invention has the following technical effects: 1. By starting the blower, the blower draws the outside gas into the air guide hood through the connecting pipe and controls it through the ball valve, thereby supplementing the combustion air, adjusting the exhaust gas concentration, ensuring complete combustion, and guiding the exhaust gas to avoid exhaust gas deviation.

[0013] 2. The filter element at the inlet of the catalytic combustion chamber removes solid particles, droplets, or larger pollutants, effectively preventing these impurities from clogging the pores of the subsequent heat storage medium or contaminating or poisoning the catalyst, thus ensuring the heat storage efficiency and long-term stability of the catalytic reaction.

[0014] 3. By periodically starting the cylinder, the extension and retraction of the telescopic rod and the movement of the scraper along the guide rod are controlled, so that the scraper scrapes through the multiple guide pipes to remove the attached ash, thereby restoring the permeability and heat exchange efficiency of the heat storage body.

Detailed Implementation

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0023] Example 1: A regenerative catalytic combustion device for waste gas, see reference. Figures 1-4As shown, the catalytic combustion chamber includes a catalytic combustion chamber 1, a horizontal partition 2, a vertical partition 3, a gas guide plate 4, an exhaust gas inlet pipe 5, an igniter 6, a guide pipe 7, a catalytic module 11, and an exhaust pipe 12. The lower part of the catalytic combustion chamber 1 is fitted with the horizontal partition 2 by welding. A vertical partition 3 is welded to the middle of the horizontal partition 2, dividing the horizontal partition 2 into two halves of equal area. Two gas guide plates 4 are fixedly connected between the horizontal partition 2 and the vertical partition 3, separated by the vertical partition 3. The exhaust gas inlet pipe 5 is connected to the lower right side of the catalytic combustion chamber 1. An igniter 6 is bolted to the bottom of the catalytic combustion chamber 1. The horizontal partition 2 is evenly spaced... Multiple guide pipes 7 are connected, and the guide pipes 7 are located above the igniter 6. A catalytic module 11 is set in the lower left part of the catalytic combustion chamber 1. The inner wall of the catalytic module 11 is stainless steel, the outer wall is carbon steel, and the middle is filled with high temperature resistant aluminum silicate fiber cotton for insulation. The top left side of the catalytic combustion chamber 1 is symmetrically connected with the gas outlet pipes 12. It also includes a gas guide hood 8, a blower 9, a connecting pipe 10, and a ball valve 1001. The gas guide hood 8 is fixedly connected to the top of the catalytic combustion chamber 1. The guide pipes 7 are connected to the gas guide hood 8. The blower 9 is symmetrically set in the top right side of the catalytic combustion chamber 1 by bolt connection. The blower 9 is connected to the gas guide hood 8 by a connecting pipe 10. The ball valve 1001 is set on the connecting pipe 10.

[0024] See Figure 3 As shown, it also includes a filter screen 18, which is provided on the air guide plate 4.

[0025] When this device is to be used, the organic waste gas enters from the waste gas inlet pipe 5 and first passes through the heat storage chamber composed of the horizontal partition 2, the vertical partition 3 and the air guide plate 4. Here, the waste gas exchanges heat with the heat storage body. The preheated waste gas is ignited by the igniter 6 and begins to burn. Subsequently, the high-temperature gas comes into contact with the catalytic module 11 and undergoes a deep oxidation reaction on the surface of the catalyst, completely decomposing the residual organic pollutants into harmless CO2 and H2O. The purified high-temperature gas is discharged from the outlet pipe 12, and the blower 9 is started. The blower 9 draws the outside gas into the air guide hood 8 through the connecting pipe 10 and controls it through the ball valve 1001. This can supplement the combustion air, adjust the waste gas concentration, ensure complete combustion, and guide the waste gas to avoid waste gas deviation.

[0026] Example 2: Based on Example 1, refer to Figure 1 , Figure 3 and Figure 5 As shown, it also includes a sliding frame 13 and a filter element 14. The sliding frame 13 is slidably arranged on the lower right side of the catalytic combustion chamber 1, and the filter element 14 is arranged inside the sliding frame 13. The filter element 14 is located on the left side of the exhaust gas inlet pipe 5.

[0027] See Figure 5As shown, it also includes a handle 19, which is fixedly connected to the sliding frame 13.

[0028] When organic waste gas enters from the waste gas inlet pipe 5, the filter element 14 at the inlet of the catalytic combustion chamber 1 removes solid particles, droplets or larger pollutants contained therein, effectively preventing these impurities from clogging the pores of the subsequent heat storage medium or contaminating or poisoning the catalyst, ensuring the heat storage efficiency and long-term stability of the catalytic reaction, and the filter element 14 can be replaced by pulling out the sliding frame 13 through the handle 19.

[0029] See Figure 2 , Figure 3 , Figure 4 and Figure 6 As shown, it also includes guide rods 15, cylinders 16 and scrapers 17. Cylinders 16 are symmetrically connected to the top of the catalytic combustion chamber 1 by bolts. Scrapers 17 are fixedly connected to the telescopic rods of cylinders 16. Scrapers 17 slide on multiple guide pipes 7. Four guide rods 15 are symmetrically fixedly connected to the top of the transverse partition 2. Scrapers 17 slide on the four adjacent guide rods 15.

[0030] During equipment operation, cylinder 16 is periodically activated to control the extension and retraction of telescopic rod and the movement of scraper 17 along guide rod 15, so that scraper 17 scrapes off the excess ash from the guide pipes 7, thereby restoring the permeability and heat exchange efficiency of the heat storage body.

[0031] See Figure 1 As shown, it also includes a support angle iron 20. The support angle iron 20 is symmetrically installed on the left and right sides of the bottom of the catalytic combustion chamber 1. The support angle iron 20 has two waist-shaped holes 21.

[0032] Before use, the entire catalytic combustion device can be firmly fixed to the foundation or steel structure platform by bolts through the waist-shaped hole 21 opened on the base plate of the support angle iron 20.
