Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment technology, specifically a waste gas treatment system. Background Technology

[0002] The waste gas generated from the compounding of ambroxol hydrochloride solution is harmful to health, possessing strong irritant properties. It can irritate the mucous membranes of the respiratory tract, including the eyes, nose, and throat, causing symptoms such as eye pain, tearing, coughing, and difficulty breathing. Therefore, the waste gas from the compounding of ambroxol hydrochloride solution needs to be treated before discharge. Waste gas spray adsorption purification is a waste gas treatment technology designed based on the principle of physicochemical absorption. This technology uses nozzles inside a spray tower to spray water mist onto the waste gas, ensuring full contact between the waste gas and the water mist. Through inertial collision, impact, and dissolution, particulate matter and soluble gaseous pollutants in the waste gas are adsorbed.

[0003] Currently, in the process of using exhaust gas spray adsorption purification equipment, although the purification liquid is sprayed into the tower by the atomizing pump to contact the exhaust gas, the fixed and single spray angle of the atomization in the tower, as well as the unidirectional flow of the exhaust gas in the tower, result in a small contact range and insufficient contact between the exhaust gas and the atomization. In addition, the exhaust gas with high humidity is prone to clogging the filter plate. Utility Model Content

[0004] The purpose of this invention is to provide a waste gas treatment system to solve the problems mentioned in the background art.

The top of the exhaust gas treatment tower 1 is equipped with an air outlet 8, realizing double-layer rotating atomization. The upper and lower inclined atomization generates impact and collision between the upper and lower layers, increasing the impact and adsorption between the atomization and the exhaust gas. The atomization space is large, which promotes the flow of exhaust gas in the tower. The exhaust gas has more sufficient contact with the atomization, improves the atomization effect, and prevents the filter holes from being blocked by exhaust gas with high humidity in the tower.

[0022] Specifically, the atomizing mechanism 3 includes a rotating tube 31 and an atomizing tube 32. The rotating tube 31 is provided inside the exhaust gas treatment tower 1.

The end of the rotating joint 33 away from the rotating tube 31 is connected to a connecting pipe 91. The other end of the rotating tube 31 is provided with a rotating mechanism. The rotating mechanism drives the rotating tube 31 to rotate in the exhaust gas treatment tower 1 to perform rotational atomization.

[0023] Furthermore, the rotating mechanism includes a transmission wheel 34, a transmission belt 35, and a first motor 36. There are two rotating tubes 31, and each of the two rotating tubes 31 has a transmission wheel 34 at the end away from the rotating joint 33. A sealing ring is provided on the exhaust gas treatment tower 1 between the transmission wheel 34 and the rotating tube 31. There are two transmission wheels 34, and the two transmission wheels 34 are connected by a transmission belt 35. A first motor 36 is mounted on one side of the exhaust gas treatment tower 1 via a motor frame. The output end of the first motor 36 is connected to the transmission wheel 34 via a coupling. The first motor 36 drives the transmission wheel 34 to rotate, and the upper and lower rotating tubes 31 are driven to rotate inside the exhaust gas treatment tower 1 through the transmission wheel 34 and the transmission belt 35.

[0024] Furthermore, the cleaning mechanism includes a second motor 6, a threaded rod 61, a cleaning plate 62, and a brush 63.

A limiting rod is provided inside the exhaust gas treatment tower 1 on one side of the threaded rod 61, and a limiting hole is provided on one side of the cleaning plate 62. The cleaning plate 62 is slidably mounted on the limiting rod through the limiting hole. The second motor 6 drives the threaded rod 61 to rotate, and the threaded sleeve on the threaded rod 61 drives the cleaning plate 62 to move back and forth below the exhaust gas filter plate 5. The brush 63 on the cleaning plate 62 cleans the filter surface of the exhaust gas filter plate 5.

[0025] Furthermore, the atomizing tubes 32 on the two rotating tubes 31 are staggered, and the atomizing nozzles on the atomizing tubes 32 are tilted away from the rotating tubes 31, resulting in impact collisions between the upper and lower tilted atomization layers.

[0026] Furthermore, the bottom of the exhaust gas treatment tower 1 is equipped with an installation plate, which is fixedly installed to the liquid supply tank 2 by bolts, making it easy to assemble and disassemble the exhaust gas treatment tower 1 and the liquid supply tank 2.

[0027] Furthermore, a filter screen is installed at the upper part of the liquid supply tank 2. The wastewater generated by the atomization of exhaust gas falls into the liquid supply tank 2 and is filtered by the filter screen. The purified liquid can be filtered and recycled.

[0028] The usage method of this embodiment is as follows: The waste gas generated during the compounding process of ambroxol hydrochloride solution is connected to the air inlet 4 through a pipe. The waste gas enters the interior of the waste gas treatment tower 1 through the air inlet 4. The waste gas flows from bottom to top inside the waste gas treatment tower 1. Under the action of the atomizing pump 10, the waste gas purification liquid in the supply tank 2 is transported to the interior of the rotating tube 31 through the supply pipe 9 and the connecting pipe 91 via the rotary joint 33. The waste gas purification liquid is atomized and sprayed into the interior of the waste gas treatment tower 1 through the atomizing nozzle on the atomizing tube 32. The first motor 36 drives the transmission wheel 34 to drive the upper and lower rotating tubes 31 to rotate inside the waste gas treatment tower 1 through the transmission wheel 34 and the transmission belt 35, realizing double-layer rotational atomization. Since the atomizing tubes 32 on the two rotating tubes 31 are staggered, the atomizing tubes 32 The atomizing nozzle of the upper atomizing nozzle is inclined away from the rotating tube 31. Therefore, the upper and lower inclined atomizing layers generate rotational impact and collision, which increases the impact and adsorption between the atomization and the exhaust gas. The atomization space is large, and the rotation promotes the multi-directional flow of exhaust gas in the tower. The exhaust gas has more sufficient contact with the atomization and the atomization effect is improved. The atomized and purified exhaust gas rises and passes through the exhaust gas filter plate 5 for filtration and purification. The filtered and purified exhaust gas rises and passes through the water-proof membrane 7 for water vapor separation. Finally, it is discharged from the exhaust gas treatment tower 1 through the outlet 8. The second motor 6 drives the threaded rod 61 to rotate. The threaded sleeve on the threaded rod 61 drives the cleaning plate 62 to move back and forth below the exhaust gas filter plate 5. The brush 63 on the cleaning plate 62 cleans the filter surface of the exhaust gas filter plate 5 to prevent the filter holes from being blocked by the high humidity of the atomized exhaust gas in the tower.
