Description

Technical Field

[0001] The utility model relates to the technical field of chemical environmental protection equipment, in particular to a waste gas treatment device for continuous production of triethylenediamine. Background Art

[0002] The waste gas treatment device for the continuous production of triethylenediamine includes a reaction tower, a dust collector and other equipment, which are used to capture and treat harmful gases generated during the production process, such as ammonia, organic volatiles, etc., to reduce pollution to the atmospheric environment and comply with national and regional environmental protection regulations.

[0003] Although current technology has many advantages, its disadvantage is that the solid particles or condensates produced during the reaction will gradually deposit on the tower wall. These solid particles or condensates will accumulate more and more, occupying the space in the tower, reducing the effective reaction volume, and affecting the exhaust gas treatment efficiency and processing capacity. When the sediment accumulates to a certain extent, it may block the air flow channel in the tower, causing gas flow to be obstructed, affecting the uniformity of gas distribution, and further reducing the treatment efficiency. In severe cases, it may even force production to be interrupted, and some motors that clean the inner wall are always driven, which reduces the service life of the motor. At the same time, during the ash unloading process, because the inside of the reaction tower is in a negative pressure state, cold air will enter the inside of the reaction tower from the ash outlet. The cold air may cause the temperature of the solid particles or condensates near the ash outlet to drop, change their physical properties, increase viscosity or cause certain components to condense, making it easier to adhere to the ash outlet. Long-term accumulation may cause blockage, further endangering the stable operation of the system. Utility Model Content

A rotating shaft 11 is fixedly installed at the bottom of the rotating block 6. Two driving blades 12 and several fixed plates 13 are fixedly installed on one side of the rotating shaft 11 close to the inside of the tower body 1. Several scrapers 14 are fixedly connected with the outer surfaces of several fixed plates 13. Cleaning mechanisms are provided on the outer surfaces of several fixed plates 13, which avoids the continuous operation of motor 4, improves the service life of motor 4, and avoids ash adhering to the inner wall of the tower body 1 and clogging of the filter plate 16.

[0024] Specifically, Figure 3 and Figure 4 As shown, an ash discharge pipe 19 is fixedly connected to the bottom of the tower body 1, and two rotating shafts three 23 are movably embedded in the inner surface of the ash discharge pipe 19, and baffles 26 are fixedly installed on one side of the two rotating shafts three 23 close to the inside of the ash discharge pipe 19, and toothed wheels 22 and rocker arms 24 are fixedly installed on one side of the two rotating shafts three 23 close to the outside of the ash discharge pipe 19, and counterweights 25 are fixedly connected to the outer surfaces of the two rocker arms 24, and a motor 20 is provided on the outer surface of the ash discharge pipe 19, and an incomplete gear 21 is provided on the outer surface of the motor 20 through a bearing, and the two toothed wheels 22 are meshedly connected to the outer surface of the incomplete gear 21, thereby preventing a large amount of cold air from entering the interior of the tower body 1 and alleviating the problem of ash blocking the discharge port.

[0025] like Figure 3 As shown, a plurality of atomizing components 27 are arranged on the top of the tower body 1, and the second rotating shaft 11 is movably embedded in the inner surface of the tower body 1. The second rotating shaft 11 can transmit power to the fixed plate 13 to make the fixed plate 13 rotate.

[0026] like Figure 5As shown, the rotating shaft 5 is movably embedded in the inner surface of the rotating block 6, and a plurality of positioning blocks 10 are fixedly connected to the inner surface of the rotating block 6. The positioning blocks 10 can fix the spring 9 and provide a good working environment for the spring 9.

[0027] like Figure 6 As shown, the cleaning mechanism includes a connecting plate 17, and the outer surfaces of several connecting plates 17 are fixedly connected to several scraper plates 18. The outer surface of the tower body 1 is fixedly connected to two connecting pipes 15, and the inner surface of one connecting pipe 15 is fixedly connected to a filter plate 16. Several connecting plates 17 are fixedly connected to the bottom of several fixed plates 13. The scraper plates 18 can clean the dust on the filter plate 16 to avoid clogging of the filter plate 16.

[0028] In the utility model, before starting the motor 4, the card block 8 is stuck on the outer surface of the rotating shaft 5, and rotates synchronously with the rotating shaft 5, the atomizing component 27 is put into use, the atomizing component 27 will spray to the inside of the tower body 1, and then the exhaust gas treatment system is started, the exhaust gas is introduced into the tower body 1 through one of the connecting pipes 15, and then discharged through another connecting pipe 15. These water mists have a large surface area and can effectively contact and adhere to the dust particles in the exhaust gas. Due to the surface tension of the water mist, the dust particles are surrounded by water droplets and gradually increase in size, lose their suspension ability, and finally settle due to gravity. The dust particles will block the filter plate 16 and adhere to the inner wall of the tower body 1. The support rod 2 and the support plate 3 can support the motor 4 and the rotating block 6. The motor 4 is started, and the motor 4 drives the rotating shaft 5 to rotate through the output shaft. The shaft 1 5 drives the clamping block 8 to rotate, and the clamping block 8 drives the rotating block 6 to rotate synchronously through the positioning rod 7, and the rotating block 6 drives the rotating shaft 2 11 to rotate, and the rotating shaft 2 11 drives the fixed plate 13 and the two driving blades 12 to rotate. Because the scraper 1 14 on the fixed plate 13 is in contact with the inner wall of the tower body 1, when the multiple fixed plates 13 rotate, the scraper 14 will clean the dust on the inner wall of the tower body 1, and the fixed plate 13 will also drive the scraper 2 18 to clean the dust on the filter plate 16 through the connecting plate 17. When the flow rate of the exhaust gas makes the rotation speed of the two driving blades 12 greater than the rotation speed of the rotating shaft 1 5, and then the rotation speed of the rotating block 6 is greater than the rotation speed of the rotating shaft 1 5, the rotating block 6 will generate a tangential force due to the rotation, and the tangential force will cause the clamping block 8 to make a circular motion with the multiple positioning rods 7 as the center, and the clamping block 8 is no longer stuck on the surface of the rotating shaft 1 5. When the clamping block 8 rotates, the springs 9 on the multiple positioning blocks 10 are stretched, so that the springs 9 obtain elastic potential energy. When the rotation speed of the rotating block 6 is lower than the rotation speed of the rotating shaft 5, the springs 9 can provide power for the clamping block 8, and the clamping block 8 is clamped on the surface of the rotating shaft 5 again and rotates synchronously with the rotating shaft 5;

[0029] When unloading dust, start the motor 20, and the motor 20 drives the incomplete gear 21 to rotate through the output shaft. When the incomplete gear 21 is meshed with the toothed wheel 22 above, it will drive the toothed wheel 22 above to rotate, and the toothed wheel 22 above will drive the upper shaft 3 23 to rotate, and the upper shaft 3 23 will drive the upper baffle 26 to rotate, so that the upper baffle 26 opens, and the dust will fall to the middle position of the two baffles 26. When the incomplete gear 21 is not meshed with the toothed wheel 22 above, the upper counterweight block 25 will use gravity to drive the upper shaft 3 23 through the upper swing rod 24. The incomplete gear 21 is meshed with the toothed wheel 22 below, which drives the toothed wheel 22 below to rotate, and the toothed wheel 22 below drives the rotating shaft three 23 below to rotate, and the rotating shaft three 23 below drives the baffle 26 below to rotate, so that the baffle 26 below is opened, and the ash will leave the interior of the tower body 1 by gravity. When the incomplete gear 21 is not meshed with the toothed wheel 22 below, the counterweight block 25 below will use gravity to drive the rotating shaft three 23 below to rotate in the opposite direction through the swing rod 24 below, thereby closing the baffle 26 below.

[0030] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
