Abstract
Description
Technical Field
[0001] This invention belongs to the field of exhaust gas technology in refractory brick firing, and particularly relates to an exhaust gas absorption device for refractory brick firing. Background Technology
[0002] Refractory bricks are becoming increasingly widely used. Generally, refractory bricks are made by mixing mineral powders such as kaolin, alumina powder, bauxite, and kyanite powder with water and sawdust in a mixer according to a certain ratio. After thorough mixing, a mixed raw material or slurry is formed, which is then vacuum extruded or cast into a green body. The green body is then fired at high temperature in a tunnel kiln. However, the high-temperature firing of the green body often generates a large amount of waste gas containing solid particles. Therefore, it is necessary to remove these harmful solid particles when discharging the waste gas. Existing methods include absorbing particles through water spraying, allowing the particles to settle downwards with the sprayed water, thus effectively separating the solid particles from the waste gas. Another method involves feeding the waste gas into an absorption tower, where water is sprayed. However, this structure cannot fully absorb solid particles, as the waste gas cannot effectively contact and absorb the sprayed water within the absorption tower. Therefore, it is necessary to upgrade the existing structure to improve the sufficiency and effectiveness of solid particle absorption in the waste gas, while also enhancing the flexibility and adjustability of the structure.

[0014] The beneficial effects of this invention are as follows: This invention features a meandering spray path within the absorption tower. By staggering the bottom, second, third, and top spray plates from bottom to top within the tower, a meandering spray path is created, consisting of the bottom air inlet, bottom ventilation opening, second-layer channel, second-layer ventilation opening, third-layer channel, third-layer ventilation opening, top channel, and top ventilation opening. This extends the path for the waste gas to receive the spray and increases the spraying time, significantly improving the effectiveness of particle absorption. Furthermore, three power mechanisms are installed on the side of the absorption tower, driving the second, third, and top spray plates and allowing for vertical adjustment. This adjusts the longitudinal height of the second, third, and top channels. When the waste gas contains a high concentration of solid particles, the longitudinal height of these channels can be reduced to decrease the waste gas flow rate and increase the spray density, thus achieving flexible adjustment.
