[0002] In the field of industrial waste gas treatment, spray towers, as the mainstream gas-liquid contact reaction devices, are widely used in industries such as chemical and power. However, traditional technologies have multiple bottlenecks: the single-stage spray structure results in short gas-liquid contact time and incomplete reaction, low removal rate of fine particles (such as oil mist below 2μm), easy formation of secondary pollution, and high equipment resistance, high energy consumption, and easy corrosion; the siphon drainage system relies on complex pipelines or additional power to maintain, increasing costs and energy consumption, and is prone to blockage and leakage due to improper installation; demisters (such as flat plate type and ridge type) are prone to "secondary entrainment" under high-speed airflow, and blade design or flushing defects exacerbate blockage, resulting in liquid carrying in the emitted gas; the stirring system mostly relies on natural mixing or traditional single-shaft mechanical stirring, which easily forms dead zones and slurry sedimentation, affecting reaction efficiency; the level of automation monitoring is low, lacking real-time monitoring and automatic adjustment of parameters such as liquid level, pH, and flow rate, resulting in large fluctuations in treatment effect and energy waste; in addition, problems such as nozzle blockage and slurry impurity accumulation require frequent shutdowns for cleaning, and wastewater discharge further aggravates the environmental burden. In view of this, in-depth research was conducted on the above problems, which led to this case. Utility Model Content

[0009] Beneficial effects
[0010] This utility model provides a waste gas treatment spray tower mechanism. It possesses the following beneficial effects: this waste gas treatment spray tower mechanism, through the deep integration of a multi-stage segmented treatment structure and an intelligent control system, achieves a balance between high-efficiency purification, stable operation, and low energy consumption. It employs partition plates to construct multi-segmented purification zones, combined with spiderweb-like diversion pipes and J-shaped siphon exhaust pipes to achieve gradual gas lifting and forced droplet settling. This, combined with the atomization neutralization of the circular spray pipes and the physical interception of the corrugated metal sheets, forms a triple purification path of "chemical neutralization - inertial collision - centrifugal separation," significantly improving the removal efficiency of acidic / alkaline pollutants. The siphon balance pipe and the liquid level differential pressure sensor constitute an intelligent liquid level control system, automatically maintaining the liquid level balance between the spray tower and the mixing tank. To avoid flooding or dry tower formation; the ultrasonic vibrator and mechanical agitator work together to effectively prevent nozzle clogging and neutralized liquid sedimentation, and the ultrasonic anti-clogging monitoring module provides real-time early warning; the integrated PLC / DCS control system with multiple parameter sensors such as liquid level, pH, pressure, flow rate, and humidity can dynamically adjust the spray pump frequency, valve opening, and agitator speed, and has fault self-diagnosis and alarm functions; the structured diversion components (such as horn-shaped diversion plates and conical blocks) reduce the pressure drop in the demisting section, and combined with the non-powered siphon drainage design, the overall energy consumption is reduced by about 30% compared with traditional equipment; the modular design is suitable for high humidity acidic waste gas treatment scenarios such as chemical and power industries, and supports the expansion of treatment capacity as needed.

[0014] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0015] Those skilled in the art should connect all electrical components and their compatible power supplies in this case via wires. Appropriate controllers and encoders should be selected according to the actual situation to meet control requirements. The specific connection and control sequence should refer to the working principle described below, where the electrical components are connected in sequence. The detailed connection methods are well-known in the art. The following mainly introduces the working principle and process, and will not describe the electrical control further.
[0016] Example
[0017] Please see Figure 1-2 Traditional spray towers typically employ a single-stage spray structure, resulting in short gas-liquid contact time and incomplete reaction. This is particularly problematic for removing fine oil mist particles smaller than 2μm, leading to contaminants escaping with the gas and causing secondary pollution. Furthermore, these equipment suffer from high resistance and energy consumption, and long-term operation is prone to corrosion and rust, affecting their lifespan. Existing siphon drainage devices require complex piping designs or additional power (such as pumps) to maintain siphon conditions, increasing equipment costs and energy consumption. Improper installation (e.g., incorrect pipe elevation or inferior materials) can also cause blockages, leaks, or siphon failure, making maintenance difficult.
[0018] Therefore, this application protects a waste gas treatment spray tower mechanism, which guides the smoke and waste gas to the bottom of the spray tower 1, divides the spray tower 1 into multiple sections by multiple partition plates, guides the smoke upward through the upward guide pipe 16, diverts the smoke through the spider web diversion pipe 17, siphons the smoke through the siphon exhaust pipe 18 above the spider web diversion pipe 17, and guides the liquid inside the mixing tank to the annular spray pipe 11 through the spray pump 12, and discharges the smoke through multiple... The atomizing nozzle 15 atomizes and neutralizes the smoke. The liquid is then directed to the distribution pipe 13 by the spray pump 12. From there, the liquid is directed to multiple feeding valves 14. Opening these valves allows the liquid to flow into the inner side of the annular spray pipe 11. Simultaneously, excess liquid is siphoned out through the upward drainage pipe 16, the spiderweb distribution pipe 17, and the siphon exhaust pipe 18. Finally, the siphon balance pipe 19 connects the spray tower 1 with the liquid inside the mixing tank. The gas is drawn upwards and mixed with the neutralized liquid by an agitator inside the mixing tank. The agitator drives the gear set on the drive end of the agitator, which in turn drives multiple agitator shafts. The fixed agitator shafts drive the agitator discs on them, which in turn drive the agitator blades on them. The agitator blades drive the spray tower 1 and the inside of the mixing tank to mix the gas and the neutralized liquid. At the same time, the gas containing moisture is guided by the horn-shaped guide plate 10 to multiple corrugated metal plates 3 on the demister support 2. The multiple corrugated metal plates 3 limit the flow of liquid. The gas is also diverted to multiple conical blocks 9 by the cooperation of the horn-shaped guide holes 7 on the inner side of the sealing plate 4 on the inner side of the spray tower 1 and the guide pipes 5 on the inner side of the guide block 6. The gas is then discharged and the liquid is drained by directing the gas to the conical blocks 9.
[0019] In summary, the waste gas is introduced from the bottom of the tower, divided into multiple treatment zones by several partition plates, and gradually lifted by the upward guide pipe 16. After the gas is diverted by the spider web diversion pipe 17, the flow rate is reduced by the J-type siphon exhaust pipe 18, which also promotes droplet settling. The spray pump 12 draws neutralizing liquid from the mixing tank and delivers it to the annular spray pipe 11 via the diversion pipe 13 and the feeding valve 14. The atomizing nozzle 15 atomizes the liquid and allows it to fully contact the waste gas to neutralize acidic / alkaline pollutants (such as SO2 and NOx). Excess liquid is discharged through... The siphon balance pipe 19 returns the liquid to the mixing tank to maintain liquid level balance; the stirrer (driven by a stirring motor) inside the tank mixes the raw materials with the neutralizing liquid, and the ultrasonic vibrator operates synchronously to prevent nozzle clogging and enhance atomization; the gas carrying droplets after treatment enters the demister, is physically intercepted by the corrugated metal sheet 3, guided by the horn-shaped guide plate 10, and further discharged by the centrifugal separation action of the conical block 9 and the horn-shaped guide hole 7 inside the guide pipe 5, and finally the dried gas is discharged; in terms of equipment monitoring, the core component (spray pump 1) 2. The stirring drive, ultrasonic vibrator, and feeding valve 14) need to monitor parameters such as flow rate, pressure, speed, and open / closed status. These parameters, along with real-time data feedback from level sensors, pH sensors, and pressure / flow sensors, are controlled automatically via a PLC or DCS system. This includes linkage adjustment of the spray pump 12's start / stop, valve opening, and stirring speed, and includes a fault alarm function. The filtration principle integrates multiple mechanisms: physical interception (corrugated metal sheet 3 traps droplets along a tortuous path), inertial collision (spider web diverter 17 forces droplet separation through siphon effect), centrifugal sedimentation (cone block 9 impacts droplets with eddy current), and chemical neutralization (atomized liquid reacts with pollutants to generate soluble salts). A siphon balance system automatically adjusts the liquid level to prevent flooding or dry tower operation. Multi-stage segmented treatment improves reaction efficiency. J-shaped pipes and balance pipes work together to achieve unpowered drainage. Mechanical stirring and ultrasonic vibration enhance mass transfer and prevent sedimentation. Structured flow diversion components reduce demisting energy consumption. Overall, it is suitable for treating high-humidity acidic waste gas in industries such as chemical and power, offering advantages of high efficiency, low consumption, and high automation.
