Technical Field
[0001] This utility model relates to the technical field of waste gas purification equipment, and in particular to a needle-column type honeycomb ceramic waste gas purification structure. Background Technology
[0002] The needle-column honeycomb ceramic exhaust gas purification structure is a high-efficiency and environmentally friendly device for treating exhaust gases. It primarily utilizes the porous structure within the honeycomb ceramic to increase the internal surface area, enabling the adsorption of some pollutant molecules in the exhaust gas. The main structure of the needle-column honeycomb ceramic exhaust gas purification device includes a honeycomb ceramic substrate, a catalyst coating, and needle-column structures. However, existing needle-column honeycomb ceramic exhaust gas purification devices suffer from short residence times of exhaust gas within the honeycomb ceramic during operation, and the purified exhaust gas cannot be quickly discharged, easily affecting subsequent exhaust gas purification and increasing the purification time. Therefore, these technical problems need to be addressed. Utility Model Content

[0009] Preferably, the diameter of the lower end of the funnel hole is larger than that of the upper end.
[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: In this utility model, the combination of the funnel hole and the air inlet pipe facilitates the rapid intake of exhaust gas and the formation of a pressurized area to generate suction when it is discharged at the other end, thereby improving the intake efficiency of exhaust gas and the discharge efficiency of purified gas; the combination of the inner ring and the air inlet pipe facilitates the replacement of the ceramic purifier, improving the convenience of equipment installation, commissioning, and subsequent maintenance; the combination of the vent hole and the spiral hole increases the exhaust gas residence time, allowing the exhaust gas to stay in the purification structure for a longer time and fully contact the catalyst, ultimately solving the problems of the purified gas not being able to be discharged quickly and the exhaust gas residence time being too short.

[0019] Example: See Figure 1-5The needle-column type honeycomb ceramic exhaust gas purification structure of this utility model includes a ceramic purifier 1, which is cylindrical in shape. Multiple equidistant air vents are perforated on the top surface of the ceramic purifier 1, and multiple equidistant funnel holes 5 are perforated on the periphery of the top surface of the ceramic purifier 1, with the air vents located inside the funnel holes 5. A top ring 2 is installed on the top surface of the ceramic purifier 1 and is fastened to the top surface of the ceramic purifier 1. An inner ring 3 is installed at the lower end of the ceramic purifier 1 and is fastened to the ceramic purifier 1, with external threads on the outer wall of the inner ring 3. An air inlet pipe 4 is installed at the lower end of the inner ring 3, and the air inlet pipe 4 is funnel-shaped and threadedly connected to the inner ring 3.

[0021] Working principle: When using this utility model, firstly, when using the needle-column honeycomb ceramic exhaust gas purifier, one end of the air inlet pipe 4 is connected to the exhaust gas outlet through a threaded connection. The exhaust gas is evenly dispersed through the funnel-shaped structure of the air inlet pipe 4 and enters the ceramic purifier 1. The exhaust gas enters through the funnel hole 5 on the outside of the ceramic purifier 1 and is quickly discharged from the other end, forming a pressurized area and generating a certain suction force, which facilitates the rapid discharge of other exhaust gases from the vent hole in the middle of the ceramic purifier 1. The multiple spiral holes facilitate the adsorption of harmful substances in the exhaust gas, thus completing the exhaust gas purification process.
