Description

Technical Field

[0001] The utility model relates to the technical field of spray towers, in particular to an acid mist waste gas treatment spray tower which realizes uniform flow and turbulent flow. Background Art

[0002] Spray towers are used as a type of waste gas treatment equipment for environmental protection. Based on their working principle, they are divided into circulating water spray towers, alkali spray towers, and acid spray towers (also known as pickling towers). Based on the tower material, they are divided into fiberglass spray towers, PP spray towers, and stainless steel spray towers.

[0003] According to announcement number CN 221333464 U, announcement date: July 16, 2024, a spray tower for treating acid mist waste gas with uniform flow and turbulence is disclosed, comprising a spray tower body, a spring fixedly connected to the inner wall of the telescopic slot, and a locking buckle fixedly connected to one end of the spring, the locking buckle being inserted and installed in the locking buckle slot, and the locking buckle slot is provided on one side of the inner wall of the filling slot, the inner wall of the filling slot is provided with a packing layer, a pull-out slot is provided on the side of the air inlet, and a fixing bracket is inserted and installed in the inner wall of the pull-out slot, and an exhaust fan is installed on the inner wall of the fixing bracket. The spray tower for treating acid mist waste gas with uniform flow and turbulence can provide stable water supply through the symmetrical structure of the ball valve, water pump and check valve, and can stably spray and gather water through the spray head, guide groove and gathering cover, thereby improving the spraying effect. The filling slot can be quickly pulled out and disassembled by the splicing slot and splicing plug, and can be flipped open by the closed cover plate, and the packing layer can be quickly replaced and used, making it more convenient to use.

[0004] In the prior art including the above-mentioned patent, a spray head arranged in a spray tower body is used to spray a treatment agent downward, and the acid mist waste gas is filled into the lower end of the spray tower body so that the acid mist waste gas is fully in contact with the treatment agent for environmentally friendly treatment. However, the spray angle of the spray head is in a downward conical shape, and the spray tower body is cylindrical. When several spray heads are arranged in the spray tower body, the position close to the middle of the tower body receives the largest amount of sprayed liquid, while the position close to the inner wall of the tower body receives the smallest amount of sprayed liquid. Therefore, due to the difference in the amount of sprayed liquid in the middle and the periphery of the tower body, the acid mist gas is easily caused to flow upward along the periphery inner wall of the tower body, which leads to insufficient contact time between the acid mist gas and the treatment liquid, resulting in low treatment efficiency.

DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solutions and advantages of the embodiments of the present disclosure more clear, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0020] like Figure 1-3 As shown, a spray tower for treating acid mist waste gas to achieve uniform flow and turbulent flow includes a tower body 1, in which a mounting plate 2 and a supporting plate 31 are arranged, a packing layer 32 is arranged on the supporting plate 31, and a plurality of spray heads 21 facing the supporting plate 31 are arranged on the mounting plate 2. A guide ring 4 is also coaxially arranged in the tower body 1 and located between the mounting plate 2 and the supporting plate 31. The inner ring surface of the guide ring 4 has an annular protrusion facing the axial direction of the tower body 1 so that a symmetrical guide slope is formed on the inner ring surface.

[0021] Specifically, such as Figure 1As shown, an air filling pipe 11 connected to the interior of the tower body 1 is provided at the lower part of the tower body 1, an exhaust pipe 12 connected to the interior of the tower body 1 is provided at the upper part of the tower body 1, and a guide ring 4 is coaxially arranged inside the tower body 1 to be located between the mounting plate 2 and the guide ring 4, and a flow groove 22 for gas flow is provided on the mounting plate 2. When the acid mist gas is filled into the interior of the tower body 1 from the air filling pipe 11, the spray head 21 sprays the treatment liquid downward, and the acid mist gas first rises through the support plate 31 and the packing layer 32 to perform preliminary impurity filtration and cleaning, and then the acid mist gas continues to rise close to the mounting plate 2. The treatment liquid sprayed from the spray head 21 cleans and environmentally treats the acid mist gas. The acid mist gas near the inner side of the tower body 1 easily flows upward along the guide slope below the inner annular surface of the guide ring 4, while flowing toward the middle of the tower body 1 to form a turbulent flow. As a result, during the spray treatment process, the acid mist gas on the outer side and the middle of the tower body 1 can flow relative to each other to form a turbulent flow, thereby improving the treatment effect and efficiency of the acid mist gas. This avoids the problem of insufficient contact time between the acid mist gas and the treatment liquid caused by the acid mist gas flowing upward along the inner wall of the tower body 1, thereby improving the treatment efficiency. Secondly, when the treatment liquid sprayed from the spray head 21 flows vertically downward along the inner wall of the tower body 1, the treatment liquid easily flows back along the guide slope above the inner annular surface of the guide ring 4 to the middle of the tower body 1 and falls vertically downward to form a secondary spray, thereby further increasing the contact area and time between the treatment liquid and the acid mist gas, improving the treatment effect of the acid mist gas, and improving the utilization rate of the treatment liquid.

[0022] In the above technical solution, the guide ring 4 is used to allow the acid mist gas on the sides and the middle of the tower body 1 to flow relative to each other to form a turbulent flow, thereby improving the treatment effect and efficiency of the acid mist gas, avoiding the problem of insufficient contact time between the acid mist gas and the treatment liquid caused by the acid mist gas flowing upward along the inner wall of the side of the tower body 1, and improving the treatment efficiency. Secondly, when the treatment liquid sprayed by the spray head 21 flows vertically downward along the inner wall of the tower body 1, the treatment liquid easily flows back to the middle of the tower body 1 along the guide slope on the upper side of the inner ring surface of the guide ring 4 and falls vertically to form a secondary spray, thereby further increasing the contact area and time between the treatment liquid and the acid mist gas, improving the treatment effect of the acid mist gas, and improving the utilization rate of the treatment liquid.

[0023] As a further embodiment provided by the present invention, the guide ring 4 is axially rotatably arranged in the tower body 1, and the inner ring surface of the guide ring 4 is provided with air guide grooves 41 arranged in a circumferential array, and the air guide grooves 41 are arranged vertically.

[0024] Specifically, such as Figure 1As shown, the guide ring 4 is rotatably arranged on the tower body 1, and an air guide groove 41 is provided on the guide ring 4. The air guide groove 41 is arranged vertically so that the acid mist gas in the middle of the tower body 1 can rise vertically along the air guide groove 41, avoiding the problem of rising pressure inside the tower body 1 due to excessive rising obstruction of the acid mist gas. Secondly, the guide ring 4 can be driven to rotate axially. At this time, the guide ring 4 can pass through the air guide groove 41 to drive the acid mist gas between the mounting plate 2 and the supporting plate 31 to rotate as a whole about the axis of the tower body 1 to achieve uniform flow of the acid mist gas in the tower body 1, further increase the contact area and time between the acid mist gas and the treatment liquid, and improve the treatment effect of the acid mist gas.

[0025] As an embodiment further provided by the present invention, a helical gear component 71 and a drive motor 72 are rotatably arranged in the tower body 1, a helical tooth portion 412 is coaxially arranged on the guide ring 4, the helical tooth portion 412 is coupled to the helical gear component 71, and the helical gear component 71 is coaxially fixed with the output shaft of the drive motor 72.

[0026] Specifically, such as Figure 2 As shown, a helical gear member 71 and a drive motor 72 are rotatably arranged in the tower body 1, and a helical tooth portion 412 is coaxially arranged on the guide ring 4. The output shaft of the drive motor 72 rotates to drive the helical gear member 71 to rotate, and the helical gear member 71 drives the guide ring 4 to rotate along its axis to evenly distribute the acid mist gas in the tower body 1, thereby improving the rotation operation stability of the guide ring 4.

[0027] As a further embodiment provided by the present invention, a rotating ring 5 is provided on the inner ring surface of the guide ring 4 so as to rotate toward the guide slope surface of the support plate 31 .

[0028] Specifically, a rotating ring 5 is rotatably provided on the inner ring surface of the guide ring 4 facing the guide slope surface of the support plate 31. When the helical gear member 71 drives the guide ring 4 to rotate axially, the rotating ring 5 is rotatably provided on the guide ring 4, so that the rotating ring 5 has a relative rotational movement relative to the guide ring 4, and then the relatively delayed rotational movement of the rotating ring 5 relative to the guide ring 4 is utilized to reduce the impact force of the guide ring 4 when the rotation starts or stops, thereby reducing the vibration of the tower body 1 and improving the service life of the tower body 1. When the flow rate of the acid mist gas near the inner side of the tower body 1 is relatively low, the acid mist gas easily passes over the rotating ring 5 along the guide slope on the lower side of the inner ring surface of the guide ring 4 and flows upward while flowing toward the middle of the tower body 1 to form a turbulent flow; and if the flow rate of the acid mist gas inside the inner side of the tower body 1 is relatively high, when the acid mist gas contacts the rotating ring 5 along the guide slope on the lower side of the inner ring surface of the guide ring 4, the inertia generated by the high flow rate of the acid mist gas will cause the high-flow-rate acid mist gas to be blocked and flow quickly toward the middle of the tower body 1 to form a blocking flow, thereby reducing the flow rising speed of the acid mist gas in the middle of the tower body 1, thereby achieving turbulent flow deceleration for the high-flow-rate acid mist gas, avoiding the problem of insufficient contact time with the treatment liquid due to excessive gas flow rate, and improving treatment efficiency.

[0029] As an embodiment further provided by the present invention, the guide ring 4 is provided with connecting holes 42 arranged in a circular array, the first end of the connecting hole 42 is inclined upward and connected to the air guide groove 41 to form an outflow port 421, and the second end of the connecting hole 42 is connected to the guide slope of the inner ring surface of the guide ring 4 facing the support plate 31 to form an inflow port 422, and the inflow port 422 is located between the rotating ring 5 and the support plate 31.

[0030] Specifically, such as Figure 2 As shown, the upper end of the connecting hole 42 is the first end, and the lower end is the second end. The flow outlet 421 at the upper end of the connecting hole 42 is located in the air guide groove 41, and the flow inlet 422 is located on the guide slope of the guide ring 4 between the rotating ring 5 and the supporting plate 31. When the acid mist gas contacts the rotating ring 5 along the guide slope on the lower side of the inner ring surface of the guide ring 4, part of the acid mist gas is blocked and flows into the connecting hole 42 from the flow inlet 422 and is ejected from the flow outlet 421 of the air guide groove 41. Since the guide ring 4 is driven to rotate to apply a circumferential rotational force to the acid mist gas entering the connecting hole 42, when the acid mist gas in the connecting hole 42 is ejected from the flow outlet 421 to the middle of the tower body 1, the acid mist gas will still move to a certain extent following the rotation direction of the guide ring 4 due to inertia, so that the gas ejected from the connecting hole 42 is used to block, slow down and turbulent the acid mist gas on the side of the air guide groove 41, thereby further improving the treatment efficiency of the acid mist gas.

[0031] As an embodiment further provided by the present invention, a rubber stopper 6 is movably provided in the guide ring 4, and the first end of the rubber stopper 6 extends into the communicating hole 42. A circumferential array of protrusions 51 is provided on the rotating ring 5. The rotating ring 5 is driven to rotate axially relative to the guide ring 4 so that the protrusions 51 rotate circumferentially in sequence to push the first end of the rubber stopper 6 to intermittently block the communicating hole 42.

[0032] Specifically, such as Figure 2 As shown, the upper end of the rubber stopper 6 is the first end, and the lower end is the second end. Figure 3 As shown, a circumferential array of protrusions 51 is provided on the rotating ring 5. Since the guide ring 4 is driven to rotate, and the rotating ring 5 is in rotational contact with the guide ring 4 only by friction, when the guide ring 4 rotates, the rotating ring 5 will randomly rotate relative to the guide ring 4 due to the change in the resistance of the acid mist gas, thereby causing the protrusions 51 to rotate circumferentially in sequence to push the second end of the rubber stopper 6. The first end of the rubber stopper 6 is pushed and randomly and intermittently blocks the connecting hole 42, thereby making the flow of the acid mist gas located in the middle of the guide ring 4 more chaotic, further improving the treatment efficiency of the acid mist gas.

[0033] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
