Description

Technical Field

[0001] This utility model relates to the field of spray tower technology, and in particular to a waste gas treatment spray tower in the preparation process of volatile compounds. Background Technology

[0002] Volatile compounds are compounds that are easily volatilized or evaporated at normal temperature and pressure. They usually have low boiling points and can exist in the air in gaseous form. They usually have a certain impact on the environment and human health. Therefore, the waste gas generated in the preparation process of volatile compounds needs to be treated by spraying in a spray tower.

[0003] A Chinese patent discloses a waste gas treatment spray tower (authorization announcement number CN212492350U). This patented technology, by setting up cotton strips, mounting rods and guide plates, achieves the effect of increasing the reaction time between waste gas and absorbent liquid to improve absorption efficiency. It solves the problems of waste gas rising too fast, waste gas contact time with absorbent liquid being short, waste gas not being able to fully react with absorbent liquid, reducing the effect of spray treatment and making it difficult to meet the needs of waste gas treatment.

[0004] However, most existing waste gas treatment spray systems use baffles to reduce the flow rate. These baffles have channels for waste gas flow, but the size of these channels is fixed and cannot be adjusted. This results in the waste gas passing through at a uniform speed, affecting the treatment effect. For example, the aforementioned comparative document uses baffles to reduce the waste gas flow rate. In practical applications, because the channels in existing baffles are fixed, the waste gas flows through these channels at a uniform speed during spraying, and the inability to adjust the channel size leads to poor flow rate reduction, which in turn affects the waste gas treatment effect during the preparation of volatile compounds. Therefore, those skilled in the art provide a waste gas treatment spray tower for the preparation of volatile compounds to solve the problems mentioned in the background art. Utility Model Content

[0012] This invention provides a waste gas treatment spray tower for the preparation process of volatile compounds, which has the following advantages compared with the prior art:

[0013] 1. This design is a waste gas treatment spray tower for the preparation process of volatile compounds.

[0015] 3.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 This utility model provides a technical solution for a spray tower for treating waste gas during the preparation of volatile compounds: It includes an upper spray tower 1 and a lower spray tower 2 with a connecting sleeve 3 on the outside. A spray pipe 11 is installed on the outside of the upper spray tower 1, and an outlet pipe 12 is installed above the upper spray tower 1. An inlet pipe 21 and a drain pipe 22 are installed on the outside of the lower spray tower 2 from top to bottom. A filter screen 23 is installed inside the lower spray tower 2, above the drain pipe 22 and below the inlet pipe 21. A fixing plate 51 is also installed inside the upper spray tower 1. A turntable 5 is rotatably mounted above the fixed plate 51. Both the turntable 5 and the fixed plate 51 have symmetrically arranged ventilation holes 52 on their upper surfaces. A support rod 53 is also provided on the inner side of the upper part 1 of the spray tower above the turntable 5. A motor 54 is installed at the middle position of the support rod 53. An adsorption mechanism 4 is also provided at the upper end of the air outlet pipe 12. This arrangement utilizes the motor 54 to work inside the upper part 1 of the spray tower, which causes the turntable 5 to rotate above the fixed plate 51. This allows for adjustment of the overlapping area between the ventilation holes 52, thereby reducing the speed of the exhaust gas and achieving better spray treatment. It is highly practical.

[0023] like Figure 3 As shown, the vent holes 52 are arc-shaped on the upper surfaces of the turntable 5 and the fixed plate 51. The support rod 53 is bolted to the inner side of the upper part 1 of the spray tower. The drive end of the motor 54 is connected to a rotating shaft. The lower end of the rotating shaft is connected to the middle position of the upper surface of the turntable 5. The operation of the motor 54 will cause the turntable 5 at the lower end of the rotating shaft to rotate. When it rotates, the area between the vent holes 52 on the turntable 5 and the vent holes 52 on the fixed plate 51 decreases. This reduces the speed at which the exhaust gas passes through the vent holes 52, thereby better achieving the purpose of exhaust gas treatment.

[0024] like Figure 2 and Figure 3As shown, spray nozzles 111 are symmetrically arranged on the lower surface of the spray pipe 11 inside the upper part 1 of the spray tower. Electric telescopic rods 31 are also symmetrically arranged on the outside of the connecting sleeve 3. Limiting holes are symmetrically opened on the outside of the upper part 1 of the spray tower. The telescopic end of the electric telescopic rod 31 is embedded in the inside of the limiting hole. The spray nozzles 111 are spray-type, so that the treatment liquid for treating the waste gas can be sprayed out to treat the upper part 1 of the spray tower. The operation of the electric telescopic rod 31 will cause its telescopic end to be embedded in the limiting hole, thus realizing the purpose of connecting the upper part 1 of the spray tower with the lower part 2 of the spray tower.

[0025] like Figure 4 As shown, the adsorption mechanism 4 includes a connecting plate 41 installed on the upper end of the exhaust pipe 12 by screws. Connecting rods 42 are symmetrically arranged on the lower surface of the connecting plate 41. Two sets of adsorption plates 43 are symmetrically arranged on the outside of the connecting rods 42. Through holes 45 are opened on the upper surface of the connecting plate 41. The adsorption plates 43 are made of activated carbon. Positioning nuts 44 are provided on both the upper and lower surfaces of the adsorption plates 43 on the outside of the connecting rods 42. This arrangement allows the connecting plate 41 to be installed and disassembled using screws. The adsorption plates 43 can be used to adsorb and treat the sprayed waste gas, thereby improving the waste treatment effect.

[0026] The working principle of this utility model is as follows: When using the waste gas treatment spray tower in the volatile compound preparation process, firstly, connect the spray pipe 11 to the external spraying equipment, and connect the inlet pipe 21 to the waste gas pipe generated during volatile compound preparation. During treatment, waste gas can be introduced into the upper part 1 and lower part 2 of the spray tower through the waste pipe. After entering, the spray pipe 11 can be connected to the spray liquid through the external equipment. After entering, the spray liquid will be sprayed outward through the nozzles 111 to achieve spray treatment of the waste gas. Impurities in the sprayed waste gas will be filtered through the filter screen 23, which can be made of stainless steel. The spray water will be discharged outward through the drain pipe 22. As the waste gas flows inside the spray tower... At this time, the operation of motor 54 will cause the turntable 5 at the lower end of the rotating shaft to rotate. When it rotates, the area between the vent hole 52 on the turntable 5 and the vent hole 52 on the fixed plate 51 will decrease. This will reduce the speed of the exhaust gas passing through the vent hole 52, thereby achieving the purpose of exhaust gas treatment. At the same time, when the exhaust gas is discharged outward through the exhaust pipe 12 after exhaust gas treatment, it will also be adsorbed by the adsorption mechanism 4. The two sets of adsorption plates 43 in the adsorption mechanism 4 can perform double adsorption treatment on the exhaust gas. The two sets of adsorption plates 43 can be removed by disassembling the connecting plate 41. At the same time, the adsorption plates 43 can be installed and disassembled by using the positioning nut 44, which is practical.

[0027] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
