Description

Technical Field

[0001] This invention relates to washing technology, and in particular to a waste gas scrubbing tower for removing pollutants that can improve the washing effect. Prior Technology

[0002] In the field of environmental protection, traditional wastewater treatment and exhaust gas purification equipment, such as packed scrubbers, has long faced problems of low efficiency, cumbersome maintenance, and insufficient automation. These devices typically rely on inclined plates at the bottom and water flushing to remove sludge, but as operating time increases, sludge accumulation can obstruct water flow channels, reducing the effectiveness of sludge removal. Although some devices are equipped with automatic cleaning systems, the inclined plate area still requires manual cleaning, increasing maintenance costs.

[0003] Patent CN2796804Y proposes a filling scrubbing tower with an inclined plate at the bottom, utilizing rinsing water and a pneumatic diaphragm pump to improve cleaning efficiency. However, this patented technology still has several shortcomings that urgently need improvement. First, although the patent introduces an automatic cleaning system that introduces rinsing water from the higher side of the inclined plate and extracts deposited sludge, its cleaning effect is still limited by water flow and sludge accumulation. Due to the inclined plate design, sludge accumulates at the bottom, and the cleaning water flow cannot thoroughly rinse every corner, easily leading to sludge buildup in certain areas and causing equipment instability. Second, while the sludge collection area and drainage system in this patent improve sludge treatment in traditional designs, the water quality is still not clean enough. Due to the design of the drainage holes, some sludge may not be completely removed, potentially affecting the overall treatment effect and increasing maintenance difficulty after long-term operation. Furthermore, although the patent mentions that the inclined plate can be manually cleaned, this design does not completely solve the cleaning problem of the inclined plate area. Manual cleaning still requires a significant amount of manpower and cannot guarantee thorough cleaning every time.

[0004] To address the shortcomings of patent CN2796804Y, further technological improvements are needed, such as optimizing water flow design, improving sludge removal efficiency, and reducing manual maintenance requirements. Traditional scrubbing tower designs suffer from problems such as sludge accumulation at the bottom of the tank and the backflow of sludge by the circulating water pump. These problems can be solved through a new generation of more refined structures and efficient sludge treatment systems, thereby improving the stability and efficiency of the system. Summary of the Invention

[0005] The purpose of this invention is to provide a waste gas scrubbing tower for removing contaminants, which can effectively improve scrubbing efficiency and reduce the accumulation of contaminants, while also improving the cleanliness of water that is repeatedly recycled.

[0006] To achieve the aforementioned objectives, the present invention provides a waste gas scrubbing tower for removing contaminants, comprising a scrubbing drum having a chamber, an air inlet and an exhaust outlet respectively communicating with the chamber, and a drain outlet communicating with the chamber; a decontamination unit disposed in the chamber of the scrubbing drum for adsorbing contaminants in the waste gas; a spraying device disposed in the chamber of the scrubbing drum for spraying water onto the decontamination unit; a water tank disposed below the chamber of the scrubbing drum; the water tank having an inclined plate for collecting water and contaminants discharged from the drain outlet of the scrubbing drum, a discharge component facing the lower part of the inclined plate, and a pumping chamber disposed on the higher side of the inclined plate; and a pumping unit having a circulating water motor for pumping water from the pumping chamber, and a pipeline connected to the circulating water motor and supplying water to the spraying device.

[0007] Therefore, the present invention features a clear separation between the pumping chamber and the inclined plate area, each performing distinct functions. The pumping chamber primarily collects and stores wastewater and sludge from the washing process, and uses a circulating water motor to pump water to the spraying device, supplying it to the cleaning unit within the washing drum for washing. This design ensures effective separation of water and sludge, preventing sludge from interfering with water flow during pumping. The inclined plate area, located below the water tank, is specifically designed to guide sludge to concentrate and discharge. The inclined plate design allows sludge to naturally settle to the bottom of the tank for easy discharge. This separation effectively prevents sludge from entering the pumping chamber, ensuring stable water quality and smooth water flow, avoiding sludge interference with the water circulation system, thereby improving the overall system's operating efficiency and ease of maintenance. This separation optimizes sludge discharge and ensures efficient operation of the water circulation system, enabling the equipment to achieve optimal treatment results while maintaining low maintenance costs.

[0008] Preferably, it includes a turbulence spray device connected to the pumping unit for spraying water upwards onto the inclined plate. This further flushes away contaminants on the inclined plate, ensuring that sludge does not accumulate on the surface, thereby improving the cleanliness of the water flow channel and the operating efficiency of the equipment.

[0009] Preferably, the inclined plate forms a filter structure through which multiple water supplies pass. This filter structure design effectively intercepts sludge and impurities, reducing their entry into the downstream system with the water flow, thus helping to maintain water quality and improve equipment efficiency.

[0010] Preferably, it includes a plurality of inclined plate support frames located below the inclined plate. This ensures the stability of the inclined plate and prevents it from shifting or deforming under the impact of water flow.

[0011] Preferably, it includes a level gauge for detecting the liquid level in the tank. This allows the system to automatically activate water replenishment or drainage functions when the liquid level is too high or too low, ensuring the system operates within the optimal liquid level range and preventing liquid level fluctuations from adversely affecting equipment operation.

[0012] Preferably, it includes a conductivity meter installed in the pipeline for detecting conductivity, and a pH meter installed in the pipeline for detecting pH value. Thus, the conductivity meter can reflect the concentration of pollutants in the water, while the pH meter can ensure that the water quality is maintained within an appropriate range, avoiding excessively high or low pH levels from affecting the system's treatment effect.

[0013] Preferably, it includes a water replenishment unit that supplies water to the tank, which can be manually controlled or automatically controlled by detecting the liquid level. This allows for flexible adjustment of the water replenishment amount based on the actual liquid level in the tank, ensuring that the liquid level in the tank is always maintained within the designed range.

[0014] Preferably, it also includes a static pressure gauge installed at the air inlet for detecting pressure, and a differential pressure gauge for detecting the pressure difference between the cleaning unit and the air inlet relative to the pressure difference between the cleaning unit and the exhaust port. Thus, the static pressure gauge can be used to monitor the gas pressure within the system, while the differential pressure gauge can help detect changes in the pressure difference between the airflows. This data helps to understand the system's operating status in real time and can provide timely warnings when system anomalies occur.

[0015] Preferably, it also includes a fan motor disposed at the exhaust port for drawing air, and an anemometer disposed at the exhaust port for detecting airflow. Thus, the fan motor helps draw air to maintain airflow within the system, while the anemometer monitors the airflow volume to ensure stable airflow that meets design requirements.

[0016] Preferably, it also includes a flow meter installed in the pipeline to detect the water flow rate. This allows the flow meter to accurately measure the water flow rate within the system and provide real-time data for necessary adjustments or monitoring, helping to maintain the stability and efficiency of the equipment operation.

[0017] The detailed structure, features, manufacturing, assembly, and usage of the waste gas scrubbing tower purification equipment provided by this invention will be described in the subsequent detailed description of the embodiments. However, those skilled in the art should understand that such detailed descriptions and the specific embodiments listed for implementing this invention are merely illustrative and not intended to limit the scope of the patent application. Simple Explanation of the Diagram

[0018] The following description, with reference to embodiments and accompanying drawings, further illustrates the waste gas scrubbing tower purification equipment provided by the present invention, wherein:

[0019] Figure 1 is a schematic diagram of a preferred embodiment of the waste gas scrubbing tower for removing pollutants according to the present invention. Figure 2 is a schematic diagram of another preferred embodiment of the waste gas scrubbing tower for removing pollutants according to the present invention. Implementation

[0020] First, it should be noted that the technical features provided by this invention are not limited to the specific structures, uses, and applications described in the embodiments. All terms used in the description are illustrative descriptive terms that can be understood by those skilled in the art. The directional terms such as "front," "up," "down," "back," "left," "right," "top," "bottom," "inner," and "outer" mentioned in this specification are merely illustrative descriptive terms based on normal usage directions and are not intended to limit the scope of the claims.

[0021] As shown in Figure 1, the waste gas scrubbing tower cleaning device 1 provided in a preferred embodiment of the present invention mainly includes a scrubbing drum 10, multiple cleaning units 20, a spraying device 30, a demisting unit 40, a water tank 50, a water pumping unit 70, a turbulence spraying device 80, and a water replenishment unit 90.

[0022] The waste gas scrubbing tower pollution removal equipment 1 also includes a static pressure gauge A, a differential pressure gauge B, a fan motor C1, an air volume meter C2, a flow meter D, a conductivity meter E, an acid-base meter F, and a liquid level gauge G.

[0023] The washing drum 10 has a chamber 11, an air inlet 13, an exhaust outlet 14, two windows 15, and a drain outlet 16. The chamber 11 is formed inside the washing drum 10. The air inlet 13 is located on one side of the chamber 11, the exhaust outlet 14 is located on the other side of the chamber 11, the windows 15 are respectively located near the air inlet 13 and the exhaust outlet 14, and the drain outlet 16 is located below the chamber 11.

[0024] The decontamination unit 20 is disposed within the chamber 11 of the washing drum 10 to adsorb contaminants in the exhaust gas. The decontamination unit 20 may include, but is not limited to, Raschig rings. Furthermore, the decontamination unit 20 may use other types of adsorption materials or structures as needed, such as ceramic or metal fillers. These materials typically possess strong adsorption performance and high-temperature resistance, enabling them to operate stably for extended periods in more demanding operating environments. The design of the decontamination unit 20 can be adjusted according to the specific application requirements to achieve a more efficient contaminant adsorption effect.

[0025] A spraying device 30 is installed within the chamber 11 of the washing drum 10 to evenly spray water onto the cleaning unit 20. The spraying device 30 may consist of nozzles, a piping system, and a flow control device, which work together to evenly distribute water across the entire surface of the cleaning unit 20. The nozzle design can be adjusted as needed; for example, different orifice diameters can be used to change the spray range and droplet size to achieve optimal water distribution. To ensure stable spraying, the spraying device 30 may also be equipped with a flow control device to regulate the water flow rate and spray pressure, ensuring even water distribution without damaging the cleaning unit 20.

[0026] A defogging unit 40 is positioned between the cleaning unit 20 and the washing drum 10 to remove mist. Furthermore, to improve defogging efficiency, the defogging unit 40 can be designed to be adjustable, allowing it to automatically adjust according to different operating conditions to achieve optimal defogging performance. For example, the device may be equipped with an automatic humidity sensor to adjust the defogging intensity based on changes in air humidity to maintain stable operation.

[0027] A water tank 50 is located below the chamber 11 of the washing drum 10 to collect water and waste discharged from the drain outlet 16 of the washing drum 10. The water tank 50 has an inclined plate 51, an inclined plate support frame 52, a drain member 53, a full-water drain pipe 54, a water tank partition 55, and a water-drawing chamber 56. The top surface of the inclined plate 51 collects water and waste discharged from the drain outlet 16 of the washing drum 10. The inclined plate 51 may or may not have a filter structure through which multiple water supplies pass. The inclined plate support frame 52 supports the inclined plate 51. The drain member 53 is located at the lower part of the inclined plate 51. The full-water drain pipe 54 drains excess water from the water tank 50 at a predetermined level. The water tank partition 55 isolates the inclined plate 51 in one area. The water-drawing chamber 56 is located in another area of ​​the water tank partition 55 and can communicate with one area of ​​the inclined plate 51 through the top of the water tank partition 55 or any through-hole.

[0028] The pumping unit 70 includes a circulating water motor 71 and a pipeline 72. It pumps water from the water tank 50 and connects to the spraying device 30 to provide a water source. The circulating water motor 71 can be controlled according to the liquid level, flow rate, and pressure, and has interlocking protection functions. For example, when the liquid level is too low, the system will activate an automatic water replenishment mechanism; when the water flow rate or water pressure is abnormal, it will automatically adjust or issue an alarm.

[0029] The turbulence-spraying device 80 is connected to the pumping unit 70 to provide a water source, which sprays water onto the top surface of the inclined plate 51 to impact the sludge and move it to the lower part of the inclined plate 51. The spray angle and flow rate of the turbulence-spraying device 80 can usually be adjusted to be optimally set according to the nature and amount of sludge. In addition, the spraying device can also be designed to be self-cleaning to prevent nozzle clogging after long-term use and ensure stable operation of the equipment.

[0030] The water replenishment unit 90 is used to replenish water to the water tank 50. Water replenishment can be manually controlled or automatically controlled based on the liquid level. The water replenishment unit 90 typically includes components such as a water pump, pipes, valves, and a liquid level sensor. The liquid level sensor monitors the liquid level in the water tank 50 in real time and transmits the data to the control system, which starts or stops the water replenishment process based on the set liquid level range. If the liquid level is too low, the water pump starts, injecting water into the water tank through the valve. When the liquid level reaches the preset standard, the water replenishment process automatically stops.

[0031] A static pressure gauge A is installed outside the air inlet 13 to sense air pressure. A differential pressure gauge B is installed between the cleaning unit and the air inlet relative to the cleaning unit and the exhaust port to sense the pressure difference. A fan motor C1 is installed outside the exhaust port 14 to exhaust air. An airflow meter C2 is installed outside the exhaust port 14 to sense the airflow. A level gauge G is installed in the water tank 50 to sense the liquid level in the water tank 50. A conductivity meter E is installed in a pipe connected to the return water tank 50 to sense conductivity. A pH meter F is installed in a pipe connected to the return water tank 50 to sense pH value. The conductivity meter E and the pH meter F are connected to the return water tank 50 pipe, but can also be connected to the pipe 72 leading to the spraying device 30.

[0032] The drainage of the discharge unit 53 can be manually controlled or automatically controlled, with automatic control based on conductivity and / or liquid level detection. This can be used to determine whether the water quality meets discharge standards. If the ion concentration in the water is too high, indicating poor water quality, the system will automatically activate the drainage mechanism to remove the substandard water.

[0033] With the above structural design, the water pumping chamber 56 of this invention is located on the higher side, opposite to the location of the sludge. Therefore, the water is less susceptible to sludge contamination, resulting in better cleaning performance when reused. This invention effectively improves washing efficiency and reduces dirt accumulation, thus contributing to the achievement of the invention's objectives. The design of the water filtration structure allows water to fall below the inclined plate 51 first, which helps to make the water cleaner and further contributes to achieving the invention's objectives. The inclined plate support frame 52 ensures the stability of the inclined plate, preventing it from shifting or deforming under the impact of water flow.

[0034] By using these various sensors, precise monitoring and control of various parameters can be achieved, thereby improving the operating efficiency and stability of the equipment.

[0035] As shown in Figure 2, another preferred embodiment of the present invention is largely the same as the aforementioned embodiment, except that the washing drum adopts a vertical design, and the shape of the washing drum and the positions of the air inlet and outlet are different. Through the above design, the same function as the aforementioned embodiment can still be achieved, and the objective of the present invention can be accomplished in the same way, namely, improving the operating efficiency and washing effect of the equipment.

[0036] In addition to the above embodiments, the present invention can also be implemented in variations as follows: for example, the number and layout of the decontamination units, spraying devices, or inclined plates can be adjusted. These variations can be adjusted according to actual needs, such as increasing or decreasing the number of these devices or changing their layout under different operating environments or processing requirements, in order to optimize the decontamination effect and processing efficiency.

[0037] Furthermore, to further enhance the performance and stability of the equipment, this invention can also add other monitoring or control devices, such as smart sensors, flow controllers, and temperature and humidity sensors, to monitor the equipment's operating status in real time. These devices can assist in precisely adjusting operating parameters and automatically adapting to environmental changes, thereby ensuring stable and efficient operation of the equipment under various conditions. In addition, these additional devices can provide data feedback to help operators perform maintenance and optimization, improving the long-term reliability of the equipment.

[0038] This invention effectively addresses the shortcomings of traditional systems through a series of innovative technological improvements. Firstly, to improve cleaning efficiency, this invention employs a decontamination unit to adsorb contaminants and incorporates a spraying device to thoroughly rinse the decontamination unit. This design significantly improves cleaning efficiency, reduces sludge accumulation, and enables the equipment to maintain long-term, high-efficiency operation. This not only solves the problem of incomplete sludge removal but also reduces the maintenance burden caused by dirt accumulation.

[0039] Furthermore, the washing equipment of this invention is designed to be more automated, which is one of the biggest differences from traditional systems. While traditional systems have some automatic cleaning functions, they still require manual maintenance, especially in cleaning the drain holes and the inclined plate area. In contrast, the equipment of this invention has automatic dirt removal and rinsing functions, and can automatically adjust operating parameters without frequent manual intervention. This not only improves the operational stability of the system but also significantly reduces labor costs.

[0040] This invention also improves sludge treatment. Through the design of the water tank and pumping unit, wastewater and sludge are effectively discharged, avoiding the incomplete sludge discharge problems common in traditional systems. Furthermore, the equipment is equipped with a dedicated spraying device to remove sediment from the inclined plates, maintaining the system's high efficiency. This design ensures efficient sludge discharge, avoiding the incomplete discharge problems commonly found in traditional systems.

[0041] In terms of precise control, this invention is equipped with multiple sensors, including a level gauge (G), a conductivity meter (E), and an acid-base meter (F), enabling fine monitoring of system operation. These sensors can monitor water quality in real time and automatically adjust operating parameters based on the monitoring results, ensuring the stability of water quality and treatment effectiveness. This allows the system to better meet the treatment needs of different pollutants and improves the reliability of waste gas treatment.

[0042] Furthermore, this invention also considers environmental protection and energy conservation requirements. The system is equipped with an automatic water replenishment function and uses a circulating water system to improve water resource utilization efficiency. This design not only meets modern environmental protection standards but also reduces water waste. The equipment automatically adjusts its operation based on changes in liquid level and flow rate, effectively reducing energy consumption and achieving energy-saving effects.

[0043] Another major advantage of this invention is its ability to treat complex pollutants. Traditional systems have limited effectiveness in treating certain specific pollutants, while this invention, through a more flexible design, can efficiently treat various pollutants, including high-concentration waste gas and wastewater, and can be adjusted according to the characteristics of different pollutants, thus improving overall treatment efficiency.

[0044] In summary, compared with traditional technologies, this invention achieves significant improvements in cleaning efficiency, sludge treatment capacity, and degree of automation. By enhancing automated monitoring, improving sludge treatment efficiency, refining the cleaning process, and increasing system flexibility, it overcomes many shortcomings of traditional technologies, achieving higher treatment efficiency, lower maintenance requirements, and greater environmental benefits. This equipment not only reduces the need for manual maintenance but also greatly improves its processing capacity and operational stability. Furthermore, its environmentally friendly and energy-saving design ensures compliance with modern environmental standards, providing a new direction for the future development of wastewater and waste gas treatment equipment. Therefore, this invention provides a structurally sound and stable waste gas scrubbing tower for pollution removal, effectively achieving its objectives and possessing broad application prospects.
