[0002] Quicklime needs to be digested before use. The main purpose is to prevent the over-burned lime in the quicklime from gradually hydrating and expanding due to absorbing water vapor in the air after use, causing the hardened mortar or lime products to bulge, crack, and other damage.
[0003] When quicklime is digested, it produces calcium hydroxide when it meets water. Because calcium is relatively active, it generates high heat and produces water vapor. These vapors will carry some dust into the atmosphere during the emission process. Therefore, the smoke needs to be treated. However, the existing technology generally uses spraying to make the treatment liquid contact with the smoke to achieve the treatment of the smoke. The treated dirt remains in the smoke treatment equipment and is difficult to clean, and it is impossible to ensure that the smoke and the treatment liquid react fully, so the treatment effect of the smoke is not good.
[0004] Therefore, in order to solve the problems that the dirt residue after the above treatment is difficult to clean and the smoke treatment effect is not good, a device with easy-to-clean interior and sufficient reaction can be designed. Utility Model Content

[0026] See also Figure 1 , Figure 4 , Figure 5 and Figure 6In this embodiment, the air supply assembly includes an air pump 31 installed at the right end of the pretreatment box 1, an air inlet pipe 32 connected to the upper side of the right end of the pretreatment box 1 is installed at the inlet end of the air pump 31, and an air supply pipe 33 connected to the lower side of the left end of the purification box 2 is installed at the outlet end of the air pump 31. The sum of the number of the first baffle 81 and the second baffle 82 is not less than 4. The first baffle 81 is installed on the right inner wall of the purification box 2, and the second baffle 82 is installed on the left inner wall of the purification box 2. The upper ends of the first baffle 81 and the second baffle 82 are both inclined. The first filter 83 The first filter 74 and the second filter screen 84 are both connected to the inner wall of the purification box 2.
