Today, as environmental pollution becomes increasingly severe, waste gas treatment is an indispensable part of industrial production, and its importance is self-evident. As an important equipment for treating industrial waste gas, the improvement of the efficiency of waste gas treatment scrubbers is directly related to the effect of waste gas purification and the realization of environmental protection goals. Among the many factors that affect the efficiency of the scrubber, the optimization of the spray strategy, the efficient operation of the circulation pump and the recycling of the washing liquid are particularly critical.

The spray strategy is one of the core links in the design of waste gas treatment scrubbers, which is directly related to the contact efficiency and purification effect between the washing liquid and the waste gas. A reasonable spray strategy can ensure that the washing liquid forms a uniform and dense spray area inside the scrubber, thereby maximizing the gas-liquid contact area and improving the purification efficiency.

The layout of the nozzle is the primary task of spray strategy optimization. During the design process, it is necessary to accurately calculate and determine the optimal installation position of the nozzle according to the size, shape and flow characteristics of the scrubber. These positions should ensure that the washing liquid can fully cover the waste gas channel and avoid spray blind spots or overlapping areas. At the same time, the spacing between the nozzles needs to be considered to ensure the uniformity and density of the spraying area.

The adjustment of the spray angle and frequency is the key to further optimize the spraying effect. The selection of the spray angle should take into account the flow direction and speed of the exhaust gas, as well as the atomization effect and distribution uniformity of the scrubber. By adjusting the spray angle, the scrubber can be sprayed into the exhaust gas at the best angle, increasing the gas-liquid contact area and improving the purification efficiency. In addition, the adjustment of the spray frequency is also crucial. Too high a spray frequency may lead to waste of scrubber and increased energy consumption, while too low a spray frequency may not meet the purification needs. Therefore, it is necessary to reasonably set the spray frequency according to the actual situation to ensure that both the purification requirements are met and resources are saved.

As the core component of the scrubber circulation system, the efficient operation of the circulation pump is of great significance to ensure the spraying effect. The main function of the circulation pump is to extract the scrubber from the reservoir and pressurize it to the nozzle for spraying. Therefore, the performance of the circulation pump directly affects the spraying effect of the scrubber and the overall efficiency of the scrubber.

In order to ensure the stable circulation and efficient spraying of the scrubber, a high-efficiency circulation pump should be selected. These pumps usually have the characteristics of low energy consumption, high head, and large flow, which can ensure that the washing liquid forms a stable circulation flow inside the scrubber. At the same time, the corrosion resistance and wear resistance of the circulating pump need to be considered to deal with the corrosive substances and particulate matter that may be present in the washing liquid.

In addition to selecting a high-efficiency circulating pump, its operating parameters need to be optimized to ensure its efficient operation. This includes adjusting the pump speed, the opening of the inlet and outlet valves, and the pipeline layout. By setting these parameters reasonably, it can be ensured that the circulating pump operates under the best working conditions, reduce energy consumption and improve the circulation efficiency of the washing liquid.

The recycling of washing liquid is one of the important means to save energy and reduce environmental pollution in the exhaust gas treatment scrubber. By recycling the washing liquid, not only can the consumption and treatment cost of fresh washing liquid be reduced, but also the wastewater discharge and environmental pollution risk can be reduced.

In order to achieve the recycling of washing liquid, an effective circulation system needs to be established. This includes setting up equipment and pipelines such as liquid storage tanks, circulating pumps, filters, etc. The liquid storage tank is used to store and recycle the washing liquid; the circulating pump is responsible for extracting the washing liquid from the liquid storage tank and pressurizing it to the nozzle for spraying; the filter is used to remove impurities and particulate matter in the washing liquid to ensure its recycling effect.

In order to ensure the normal operation and effect of the washing liquid recycling system, it is necessary to strengthen its management and maintenance. This includes regularly checking the concentration, pH value and other parameters of the washing liquid to ensure that it meets the use requirements; regularly cleaning and replacing the filter element to prevent blockage and pollution; timely replenishing fresh washing liquid and treating wastewater. Through these measures, the long-term stable operation and efficient purification effect of the washing liquid recycling system can be ensured.

The optimization of the spraying strategy, the efficient operation of the circulating pump and the recycling of the washing liquid are the key ways to improve the efficiency of the exhaust gas treatment scrubber. By reasonably arranging the nozzle position, adjusting the spraying angle and frequency, and selecting a high-efficiency circulating pump, it can be ensured that the washing liquid forms a uniform and dense spraying area inside the scrubber, thereby maximizing the gas-liquid contact area and improving the purification efficiency. At the same time, by establishing an effective scrubbing liquid circulation system and strengthening its management and maintenance, the operating cost and environmental impact can be reduced, and the sustainable development of the exhaust gas treatment scrubber can be achieved. In the future, with the continuous advancement of science and technology and the continuous improvement of environmental protection requirements, the road to improving the efficiency of exhaust gas treatment scrubbers will be broader and brighter.
