And moreover, the filler balls can be added or reduced into the tower body through the observation window, so that the normal operation of the equipment is ensured.
To sum up, the utility model discloses following beneficial purpose has:
1. through the setting of air current tower for waste gas can react with bottom cleaning solution earlier before entering the air current tower, carries out the preliminary treatment. Meanwhile, when the waste gas enters the airflow tower, the waste gas can react with cleaning liquid in the airflow tower to generate kinetic energy for hedging, so that a reaction interface generates violent vibration, the waste gas floats up and down, and the waste gas treatment efficiency and treatment effect are improved;
2. through the arrangement of the low-power driving motor, a high-power motor is not needed, and the filled balls are not in a motion state at any time due to energy residue generated by kinetic energy hedging, so that the stirring pressure is greatly reduced, the energy is saved, and better treatment efficiency can be kept even without stirring;
3. the arrangement of the airflow towers further improves the treatment effect, so that the treated waste gas has better treatment effect;
4. through helical-fan's setting for during waste gas spiral enters into the air current tower, the area of contact between the waste gas that the spiral got into and the cleaning solution increases, makes the reaction better, simultaneously because kinetic energy offset is more violent, thereby guarantees that the treatment effect reaches better level.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications to the present embodiment without inventive contribution as required after reading the present specification, but all of them are protected by patent laws within the scope of the claims of the present invention.
As shown in fig. 1, a dynamic stirring spray tower comprises a tower body 1. A packing ball layer 2 is arranged in the tower body 1, and a ventilation plate 3 used for supporting the packing layer is arranged below the packing layer in the packing ball layer 2. The top of the tower body 1 is provided with a spray pipe 4 for injecting cleaning liquid. The bottom of the tower body 1 is provided with an air inlet 5, the top of the tower body 1 is provided with an air outlet 6, the bottom of the tower body 1 is provided with a liquid tank 7, and one side of the liquid tank 7 can be provided with a water pump to input the cleaning liquid back to the position of the spray pipe 4 again. Meanwhile, one side of the tower body 1 is provided with a plurality of observation windows 8 which can be used for observing the internal operation condition and increasing or decreasing the packing balls.
Example 1:
the bottom of the ventilation plate 3 is provided with a guiding device 9. The guiding means 9 comprise a gas flow tower 91. A guide slope 92 is provided in the airflow tower 91, and an intake pipe 93 is provided at the bottom of the airflow tower 91. When waste gas enters the tower body 1 through the air inlet 5 at the bottom of the tower body 1, the waste gas cannot directly flow to the packing ball layer 2 but can randomly flow in the tower body 1 due to the arrangement of the airflow tower 91. When the waste gas contacts with the cleaning liquid at the bottom, neutralization reaction occurs, and the waste gas is removed. Then, the exhaust gas enters the gas flow tower 91 through the gas inlet pipe 93, and the upper spray pipe 4 sprays the cleaning liquid, so that the exhaust gas and the cleaning liquid are converged at the packing ball layer 2. The cleaning solution contacts with waste gas at packing ball layer 2, because the waste gas direction is upwards, and the cleaning solution is downward, and both assemble and can produce kinetic energy and offset to make the rising speed of waste gas slow down, thereby keep producing violent reaction in packing ball layer 2. Due to the provision of the guide slope 92, the exhaust gas is brought into sufficient contact with the cleaning liquid, and the more vigorous the reaction thereof, the better the treatment efficiency of the exhaust gas.
The filler ball layer 2 is internally provided with blades 10, wherein the blades 10 are fixedly connected with a stirring shaft 11. The stirring shaft 11 is connected with a low-power driving motor 12 in a transmission way. The stirring shaft 11 is driven by the low-power driving motor 12 to stir, so that the filled balls keep a motion state, and the paint mist is prevented from being solidified. Meanwhile, the low-power driving motor 12 drives the stirring shaft 11 to rotate at a slower speed, but the defect of slow rotation speed of the stirring shaft 11 is compensated due to the effect of kinetic energy hedging, so that a better paint mist solidification prevention effect is achieved.
Example 2:
as shown in fig. 2, the difference from embodiment 1 is that two guide devices 9 are provided, and so on. Two guiding device 9 settings for waste gas can realize preliminary kinetic energy when not reaching the packing layer and offset the process, thereby waste gas has already partly been handled when not reaching the packing layer, has improved throughput on the one hand, and on the other hand has reduced the phenomenon of the coating cloud solidification in the packing ball more.
Example 3:
as shown in fig. 3, the difference from embodiment 1 is that the air inlet 5 and the bottom of the airflow tower 91 are provided with a spiral fan conveying pipe 13. Through helical fan pipeline 13 for the spiral air inlet when waste gas advances, the spiral air inlet makes the rising mode of waste gas spiral, prolongs the movement time of waste gas, makes the treatment effect better, and simultaneously, the spiral mode has improved the area of contact of waste gas with the cleaning solution, makes both kinetic energy offset effects better, and exhaust-gas treatment efficiency is higher.
Example 4:
as shown in fig. 4, the difference from embodiment 1 is that no blade 10, no stirring shaft 11, and no low-power driving motor 12 are provided in the tower body 1.
Example 5:
as shown in fig. 5, the difference from embodiment 2 is that no blade 10, no stirring shaft 11, and no low-power driving motor 12 are provided in the tower body 1.
Example 6:
as shown in fig. 6, the difference from embodiment 3 is that no blade 10, no stirring shaft 11, and no low-power driving motor 12 are provided in the tower body 1.
The common effects of the embodiments 4, 5 and 6 are as follows: due to the arrangement of the guiding device 9, the processing pressure of the filler ball layer 2 is smaller, and due to the action of kinetic energy to offset, the waste gas and the cleaning solution generate violent reaction oscillation in the filler ball layer 2, so that an initial movement force is kept for the filler ball layer 2, and the paint mist in the filler ball layer 2 is prevented from being solidified. Meanwhile, the device can keep the filled balls in a motion state all the time without stirring, thereby greatly saving energy and improving the treatment efficiency.
