Embodiment 1
[0127] like figure 1 , figure 2 As shown, in the acetic acid steam impurity removal production line described in this embodiment, the main body 1 includes a first main body 11 and a second main body 12 communicated inside, and the first-stage impurity removal device is arranged inside the second main body 12 . The second body 12 is disposed above the first body 11 .
[0128] Furthermore, in the acetic acid steam impurity removal production line in this embodiment, the feeding device 3 is arranged on the first body 11 . The feeding device 3 is arranged at one end of the first body 11 .
[0129] Furthermore, in the acetic acid steam impurity removal production line in this embodiment, the discharge device 4 is arranged on the second body 12 . The discharge device 4 is disposed at the end of the second body 12 opposite to the connection position of the first body 11 .
[0130] Furthermore, in the acetic acid steam impurity removal production line in this embodiment, its prim...
Embodiment 2
[0133] like figure 1 , figure 2 As shown, the difference between the acetic acid steam impurity removal production line described in this embodiment and the above embodiments is that the primary impurity removal device includes a first impurity removal device 21 and a second impurity removal device 22 at different locations. The first impurity removal device 21 is used to remove the raw material acetic acid and / or the solid impurities generated when the acetic acid is vaporized, and the second impurity removal device 22 is used to remove the raw material acetic acid and / or the liquid and / or foamy impurities generated when the acetic acid is vaporized.
[0134] Further, the distance between the second impurity removal device 22 and the discharge device 4 is smaller than the distance between the first impurity removal device 22 and the discharge device 4 .
[0135] Through the steam impurity removal production line in diketene production introduced in this example, the primary...
Embodiment 3
[0138] like figure 1 , figure 2 As shown, the difference between the acetic acid steam impurity removal production line described in this embodiment and the above-mentioned embodiments is: the acetic acid steam impurity removal production line, its first impurity removal device 21 includes a support part 211 and a first removal device arranged on the support part 211 The miscellaneous function part 212, the support part 211 is connected with the main body 1, and the first miscellaneous function part is arranged above the support part. The first impurity removal function part includes an impurity removal filler, and the impurity removal filler is an acid-resistant material. Preferably, the impurity removal filler is made of S31603 stainless steel. More preferably, the size of the impurity removal filler is Ф40mm. The filling method of the impurity-removing filler is random pile.
[0139] Further, the second impurity removal device 22 of the acetic acid steam impurity removal...
