Embodiment approach
[0050] As an embodiment of the present invention, the top perimeter of the arc-shaped side of the conical block 10 is fixed with a second water absorbing streamer 30 evenly distributed; A water-absorbing cotton thread 31; the second water-absorbing streamer 30 is folded on the upper surface of the circular ring 9 in the initial state;
[0051] During operation, the second water-absorbing streamer 30 absorbs the reactant solution falling on the upper surface of the circular ring 9 and transmits it to the first water-absorbing cotton thread 31, because the exhaust gas enters the second reaction chamber through the gap between the conical block 10 and the rubber pad 42 14. The exhaust gas flow drives the second water-absorbing streamer 30 and the first water-absorbing cotton thread 31 to float upward, so that the reactant solution on the first water-absorbing cotton thread 31 is thrown out and falls to form water droplets, thereby increasing the contact area with the exhaust gas, ...

The invention belongs to the technical field of chemical processing waste gas purification, and particularly relates to a chemical processing waste gas purification method. A purification tower comprises a tower body; the inner wall of the tower body is fixedly connected with a first partition plate; a circular ring is fixedly connected to the inner wall of the tower body above the first partition plate; a conical block is arranged in the center of the circular ring; a rotating pipe is fixedly connected to the middle of the upper surface of the conical block; the upper end of the rotating pipe passes through a fixedly connected second partition plate; a rotating disc is fixedly connected to the rotating pipe above the second partition plate; a space in the tower body between the first partition plate and the circular ring is a first reaction cavity; a space in the tower body between the circular pipe and the second partition plate is a second reaction cavity; and the inner space of the tower body above the second partition plate is a liquid inlet cavity. The air pressure serves as a power source, the amount of a reactant solution is controlled through the inlet amount of waste gas, cost waste is avoided, the solution forms water drops through airflow, the contact area with the waste gas is increased, the reaction rate is increased, and the reaction speed is increased.
Description
technical field [0001] The invention belongs to the technical field of chemical processing waste gas purification, in particular to a chemical processing waste gas purification method. Background technique [0002] Chemical waste gas refers to the toxic and harmful waste gas discharged from chemical production in the process of chemical production. Chemical waste gas often contains many types of pollutants, complex physical and chemical properties, and different toxicity, which seriously pollutes the environment and affects human health. Exhaust gas is generally treated by purification towers, but the purification rate and purification speed of traditional exhaust gas purification towers are slow, and the usage of purified reactant solution cannot be accurately controlled. [0003] In the prior art, most of the chemical processing waste gas purification methods currently use a purification tower to purify the waste gas. In the process of purifying the waste gas by the purifi...
