Description

Technical Field

[0001] This utility model relates to the field of exhaust gas treatment tower technology, specifically an environmentally friendly exhaust gas absorption tower. Background Technology

[0002] With rapid industrialization, exhaust gas emissions have become increasingly serious. Environmentally friendly exhaust gas absorption towers, as an important exhaust gas treatment device, are widely used in industries such as chemical, metallurgy, and power. Existing exhaust gas absorption towers typically use packing layers to increase the gas-liquid contact area, thereby improving exhaust gas treatment efficiency.

[0003] However, in actual operation, the packing layer is prone to blockage due to particulate matter accumulation, chemical reaction product deposition, or uneven liquid distribution, which leads to a decrease in gas-liquid contact efficiency, an increase in equipment operating resistance, and even affects the treatment effect of exhaust gas.

[0004] Currently, common solutions to the problem of packing blockage include periodic shutdown for cleaning or replacement of the packing. However, this not only increases maintenance costs but also affects the continuous operation of the equipment.

[0005] Therefore, we propose an environmentally friendly exhaust gas absorption tower. Utility Model Content

[0006] (a) Technical problems to be solved To address the shortcomings of existing technologies, this utility model provides an environmentally friendly exhaust gas absorption tower with a vibration structure that drives the plate supporting the packing to vibrate up and down, thereby improving the problem of easy clogging of the packing and effectively solving the problems in the background technology.

[0007] (II) Technical Solution To achieve the above objectives, the technical solution adopted by this utility model is as follows: an environmentally friendly exhaust gas absorption tower, comprising a tower body, an air inlet provided at the lower part of one side of the outer surface of the tower body, an exhaust outlet provided at the top of the tower body, a demister installed at the upper part of the inner cavity of the tower body, a treatment liquid spraying structure installed inside the tower body, and a packing support assembly provided at the lower part of the treatment liquid spraying structure. The packing support assembly includes a bracket, a motor, a rotating shaft, a cantilever arm, a transmission arm, a first connecting shaft, a honeycomb perforated material support plate, a baffle ring, an inverted concave frame, a second connecting shaft, a guide ring, a guide rod, and a grid material rack. The bracket is fixedly installed on one side of the outer surface of the tower body, the motor is fixedly installed at one end of the bracket, the rotating shaft is connected to the outer surface of one end of the motor, and one end of the rotating shaft extends into the interior of the tower body.

[0008] Preferably, the suspended boom, transmission boom, first connecting shaft, honeycomb hole material support plate, material stop ring, inverted concave frame, second connecting shaft, guide ring, guide rod and grid material frame are all located inside the tower body, and the suspended boom is fixedly installed on the outer surface of the rotating shaft at the end away from the motor.

[0009] Preferably, a sealed bearing is provided between the rotating shaft and the tower body, the rotating shaft is rotatably connected to the tower body through the sealed bearing, a coupling is provided between the rotating shaft and the motor, and the outer surface of one end of the rotating shaft is fixedly connected to the outer surface of one end of the output shaft of the motor through the coupling.

[0010] Preferably, the first connecting shaft is rotatably connected between the end of the cantilever arm away from the rotating shaft and the lower end of the transmission arm, the inverted concave frame is fixedly installed in the middle of the lower outer surface of the honeycomb hole material support plate, and the second connecting shaft is rotatably installed between the inverted concave frame and the upper end of the transmission arm.

[0011] Preferably, the guide rod is fixedly installed on the left and right sides of the lower outer surface of the honeycomb perforated material support plate, the guide ring is fixedly installed on the left and right sides of the inner cavity of the tower body, the guide rod passes through the guide ring, and the outer wall of the guide rod and the guide ring are slidably connected.

[0012] Preferably, the grid-shaped material rack is fixedly installed on the upper outer surface of the honeycomb hole material support plate, and the baffle ring is fixedly installed between the outer wall of the grid-shaped material rack and the upper outer surface of the honeycomb hole material support plate.

[0013] (III) Beneficial Effects Compared with the prior art, this utility model provides an environmentally friendly exhaust gas absorption tower, which has the following beneficial effects: 1. This environmentally friendly exhaust gas absorption tower effectively improves the problem of packing blockage. Through the motor-driven mechanical transmission structure in the packing support component, the honeycomb support plate vibrates up and down, keeping the packing layer in a dynamic and loose state, avoiding blockage caused by the deposition of particulate matter or chemical substances. The vibration function, combined with the flushing effect of the treatment liquid spray structure, can promptly remove the adhering substances on the surface of the packing, significantly extending the cleaning cycle and service life of the packing.

[0014] 2. This environmentally friendly tail gas absorption tower has a uniform and stable packing distribution. The baffle ring and grid rack limit the packing, ensuring that the packing will not shift or accumulate during vibration and will always maintain a uniform distribution, thereby improving the gas-liquid contact efficiency.

[0015] 3. This environmentally friendly exhaust gas absorption tower reduces maintenance costs and improves operating efficiency. It eliminates the need for frequent shutdowns for cleaning or replacement of packing materials, thereby reducing maintenance costs and production interruption time. It also enhances the continuous operation capability of the equipment. The automated vibration function reduces the need for manual intervention, making it easy to operate and suitable for large-scale industrial applications. Attached Figure Description

The cantilever boom 10 is fixedly installed on the outer surface of one side of the rotating shaft 9, away from the motor 8. A sealed bearing is provided between the rotating shaft 9 and the tower body 1, and the rotating shaft 9 is rotatably connected to the tower body 1 through the sealed bearing. A coupling is provided between the rotating shaft 9 and the motor 8, and the outer surface of one end of the rotating shaft 9 is fixedly connected to the outer surface of one end of the output shaft in the motor 8 through the coupling. The first connecting shaft 12 is rotatably connected to the cantilever boom 10 away from the rotating shaft 9. One end is between the lower end of the transmission arm 11 and the lower end of the inverted concave frame 15, which is fixedly installed in the middle of the lower outer surface of the honeycomb hole material support plate 13. The second connecting shaft 16 is rotatably installed between the inverted concave frame 15 and the upper end of the transmission arm 11. The guide rod 18 is fixedly installed on the left and right sides of the lower outer surface of the honeycomb hole material support plate 13.
