As shown in fig. 1 and 2, the embodiment provides a production waste gas absorption apparatus, which comprises a tower body 1, wherein the tower body 1 is vertically arranged on the ground, a liquid storage tank 2 is arranged at the upper end in the tower body 1, a treatment liquid is contained in the liquid storage tank 2, a liquid inlet pipe 3 communicated with the liquid storage tank 2 is further connected to the tower body 1 so as to conveniently supplement the treatment liquid into the liquid storage tank 2, an air inlet pipe 4 and an air outlet pipe 5 communicated with the tower body 1 are arranged below the liquid storage tank 2, a partition plate 7 for dividing the tower body 1 into the liquid storage tank 2 and an absorption section 6 is fixedly connected to the tower body 1, a mixing cylinder 8 is fixedly connected to the lower plate surface of the partition plate 7, the upper end and the lower end of the mixing cylinder 8 are respectively communicated with the liquid storage tank 2 and the absorption section 6, the air inlet pipe 4 is communicated with the mixing cylinder 8, wherein a liquid outlet pipe 9 communicated with the bottom of the absorption section 6 is further arranged on the tower body 1, so as to lead the waste liquid generated after the absorption treatment out of the device.

In the above embodiment, the liquid storage tank 2 is used for loading the treatment liquid, the production waste gas is introduced into the mixing cylinder 8 through the gas inlet pipe 4, and is in contact mixing with the treatment liquid directly from the liquid storage tank 2 in the mixing cylinder 8, and then the treatment waste gas and the treatment liquid enter the absorption section 6 together for subsequent chemical reaction; after the production waste gas is introduced, the production waste gas is introduced into the mixing cylinder 8 with a smaller space to contact with the treatment liquid, so that the contact efficiency of the treatment liquid and the production waste gas can be improved, and the aim of improving the purification efficiency of the production waste gas is finally fulfilled;

the absorbing device that this embodiment provided impels process gas and treatment fluid to carry out the compulsory mixture in mixing drum 8 through in leading-in space of process gas is less than the absorption tower by a lot of mixing drum 8, can improve the contact efficiency of process gas and treatment fluid to reached and improved this absorbing device to the purpose of process gas treatment efficiency.

Preferably, the partition plate 7 is provided with a plurality of liquid discharge holes 10 surrounding the mixing cylinder 8, and the treatment liquid in the liquid storage tank 2 enters the absorption section 6 through the liquid discharge holes 10, and is mixed with the gas-liquid mixture forcibly mixed in the mixing cylinder 8 again to perform a chemical reaction, so that the contact efficiency is further improved.

Preferably, the lower plate surface of the partition plate 7 is further fixedly connected with a separation barrel 11 sleeved outside the mixing barrel 8, the lower liquid hole 10 is communicated with the separation barrel 11, the lower end surface of the separation barrel 11 is positioned below the lower end surface of the mixing barrel 8, and the exhaust pipe 5 is positioned above the lower end surface of the mixing barrel 8.

The mixing cylinder 8 and the lower liquid hole 10 are surrounded in the separating cylinder 11, so that the generated waste gas entering the tower body 1 can leave from the lower end of the separating cylinder 11 only after being mixed for the first time (namely, forced mixing) and mixed for the second time (namely, after being mixed for the second time with the treatment liquid from the lower liquid hole 10) in the separating cylinder 11, and then can leave the device from the exhaust pipe 5, so that the chemical reaction between the produced waste gas and the treatment liquid is more sufficient, and the waste gas components in the discharged gas are less.

In order to guarantee that waste gas can fully contact with the treatment fluid in mixing drum 8, this absorbing device is still including installing motor 12 on 1 top of the body of the tower, and motor 12's pivot and the coaxial connecting axle 13 fixed connection who sets up in the body of the tower 1, the lower extreme of connecting axle 13 is followed liquid storage tank 2 penetrates and passes mixing drum 8, then with the interior bottom surface of body of the tower 1 rotates and is connected, still around being provided with on connecting axle 13 and being located first spiral section 14 in mixing drum 8.

When waste gas is led in from intake pipe 4, motor 12 starts to drive connecting shaft 13 and first spiral section 14 on it is rotatory (carry the treatment fluid downwards when first spiral section 14 is rotatory), at this moment, waste gas and treatment fluid can be more abundant mixture under the stirring of first spiral section 14, in order to reach better contact efficiency, go on in order to guarantee that the contact is high-efficient, feed liquor pipe 3 is located the upper end of mixing drum 8 with the intercommunication department of mixing drum 8, and be close to division board 7 as far as possible.

Along with the operation of the absorption device, the liquid level of the absorption section 6 at the lower end in the tower body 1 rises along with the operation of the absorption device until the liquid level exceeds the lower end surface of the separation cylinder 11, at the moment, gas needs to enter liquid below the liquid level and then can enter the separation cylinder 11 to exit from the exhaust pipe 5, in order to enable the gas to smoothly enter and exit the liquid, a second spiral section 15 extending from the inside of the separation cylinder 11 to the outside is further arranged on the connecting shaft 13 in a surrounding mode, and the pitch of the upper end of the second spiral section 15 is smaller than that of the lower end of the second spiral section 15.

When the motor 12 is operated, the second spiral section 15 also rotates, and the rotation of the second spiral section 15 stirs the liquid in the absorption section 6, so that the gas in the separation cylinder 11 can more easily enter the liquid and be separated from the liquid (when stirring, the component capable of reacting with the liquid continuously reacts, and the component incapable of reacting with the liquid quickly enters the liquid while stirring, and then is discharged to the outside of the separation cylinder, so that the separation from the liquid is realized);

in order to lead the gas from the separating cylinder 11 to the outside of the separating cylinder 11 more quickly, the first spiral section 14 and the second spiral section 15 rotate in the same direction, and the gas in the separating cylinder 11 is pushed downwards to enter the liquid more quickly when rotating.
