Description

[0002] Chemical flue gas is a mixture of gas and soot, with complex components, usually including water vapor, sulfur dioxide, etc. The emission of flue gas is one of the causes of air pollution. Therefore, it is crucial to treat chemical flue gas before emission.

[0003] During treatment, chemical flue gas is generally introduced into the treatment liquid to absorb and remove harmful gases in the chemical flue gas by using the treatment liquid, so as to achieve the purpose of purifying the flue gas. However, in the actual treatment process, when the chemical flue gas is introduced into the treatment liquid, the flue gas will directly overflow and discharge. At this time, the contact time between the flue gas and the treatment liquid is short, resulting in insufficient contact between the two. That is, when discharging, part of the flue gas does not contact the treatment liquid, resulting in a small amount of harmful gases still remaining in the treated flue gas, and the treatment effect is not good.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. The rotating No. 2 bearing shaft can drive the swing frame to rotate, and then drive the connecting rod to move, so that the push seat can continuously reciprocate up and down. When the push seat moves downward, the extrusion rod and the extension frame will be driven and move downward synchronously. At this time, the downward extrusion rod will push the extrusion head to push the chemical fume located in the vertical section inside the L-shaped shell downward through the extrusion head, so that it is squeezed into the treatment liquid in the horizontal section inside the L-shaped shell. When the extrusion head is pushed, the positioning ear just counteracts the positioning seat, so that the extrusion head will not continue to move, and at the same time, the extension frame The pressing ear presses on the push cap seat, and then the push seat continues to drive the extrusion rod and the extension frame to move downward. At this time, the extrusion rod slides downward in the extrusion head to adapt to the contraction deformation of the spring so that the downward movement operation will not be hindered. The downward extension frame will press the push cap seat through the pressing ear to move it downward, thereby driving the inclined frame to move to push the cap rod, so that the discharge cap on the cap rod can slide in the internal horizontal section of the L-shaped shell. At the same time, the moving cap rod will also drive the hook frame to move, causing the hook frame to move sideways to release the pull on the hook ear, so that the opening spring can gradually restore its deformation. , so as to push open the sealing cover and open the side end of the L-shaped shell, so that the discharge cap can push out the treatment liquid dissolved with chemical fume during the sliding process, and then the push seat moves up. At this time, the extrusion rod slides up in the extrusion head and gradually recovers the deformation of the adaptation spring. When the protrusion slides to the top of the extrusion head, the extrusion rod will use the protrusion to pull the extrusion head, so that the extrusion head moves up and resets, so that the chemical fume in the intake pipe can enter the internal vertical section of the L-shaped shell. At the same time, when the extended frame moves up, the top ear on it will press against the lower end of the push cap seat to The cap seat is pushed and pulled to slide the discharge cap back to its original position. During the resetting process, the treatment liquid around the side end of the L-shaped shell will re-enter the internal horizontal section of the L-shaped shell. When the discharge cap is fully reset, the end of the hook frame will pull the hook ear again to press the sealing cover onto the L-shaped shell for sealing. This cycle is repeated to continuously squeeze the chemical fume and quickly dissolve it in the treatment liquid, so that the chemical fume and the treatment liquid can fully contact each other and the harmful gases in the chemical fume can be fully absorbed and removed by the treatment liquid, thereby improving the treatment effect.

[0015] 2. When the servo motor drives the No. 2 load-bearing shaft to rotate, it will also drive the large gear on the No. 1 load-bearing shaft to rotate, and then drive the small gear to rotate quickly, so that the push flow plate on the plate shaft pushes the treatment liquid at the side end of the L-shaped shell to make it flow, so that the treatment liquid in the treatment box can flow to the L-shaped shell and enter the interior of the L-shaped shell, thereby ensuring that the treatment liquid in the treatment box is fully utilized.

At this time, the extrusion rod 18 slides downward in the extrusion head 17 and adapts to the contraction and deformation of the spring 33, so that the downward movement operation will not be hindered. The downwardly moving extension frame 21 will press the cap push seat 41 through the pressing ear 22 to move it downward, thereby driving the inclined frame 40 to move, so as to push the cap rod 31, so that the discharge cap 30 on the cap rod 31 can slide in the internal horizontal section of the L-shaped shell 16, and at the same time, the moving cap rod 31 will also drive the hook frame 25 to move, so that the hook frame 25 moves sideways to release the The pull of the hook ear 27 allows the opening spring 35 to gradually restore its deformation, so as to push open the sealing cover 29 and open the side end of the L-shaped shell 16, so that the discharge cap 30 can push out the treatment liquid dissolved with chemical fumes during the sliding process, and then the push seat 9 moves up. At this time, the extrusion rod 18 slides up in the extrusion head 17, and the adaptation spring 33 gradually restores its deformation. When the protrusion 32 slides to the top of the extrusion head 17, the extrusion rod 18 will use the protrusion 32 to lift the extrusion head 17, so that the extrusion head 17 moves up and resets, so that the chemical fumes in the intake pipe 2 can enter the internal vertical section of the L-shaped shell 16. At the same time, when the extension frame 21 moves up, the top ear 2 thereon 3 will press against the lower end of the push cap seat 41 to lift the push cap seat 41 so that the discharge cap 30 slides and resets. During the reset process, the treatment liquid around the side end of the L-shaped shell 16 will enter the internal horizontal section of the L-shaped shell 16 again. When the discharge cap 30 is completely reset, the end of the hook frame 25 will pull the hook ear 27 again, so that the sealing cover 29 is pressed on the L-shaped shell 16 for sealing.
