INTRODUCTION

The waste gas purification tower, as a key equipment in the field of industrial waste gas treatment, usually has an upright tower-like structure. Its design is scientific, reasonable and quite practical, enabling it to fit well into various industrial production environments. Its outer shell is mostly made of high-quality materials such as fiberglass reinforced plastic, carbon steel or stainless steel. These materials possess good corrosion resistance, sturdiness and sealing performance, which can effectively resist the erosion of waste gas and external environmental factors and ensure the long-term stable operation of the equipment.

The internal structure is ingenious. Depending on different treatment processes, it is equipped with multiple layers of core components with different functions, such as packing layers, spraying devices and demisters. The packing layers can increase the contact area between waste gas and the absorption liquid, allowing them to fully react. The spraying devices can evenly spray the absorption liquid, enabling the pollutants in the waste gas to be better captured and removed. The demisters are responsible for removing the droplets entrained in the purified gas to ensure that the discharged gas is dry and clean. Through the coordinated operation of various components, the waste gas purification tower can efficiently handle a variety of industrial waste gases and is widely used in the waste gas treatment links of numerous industries.

WORKING PRINCIPLE

When industrial waste gas containing pollutants enters the waste gas purification tower from the air inlet at the bottom of the tower, it will first flow upward under the guidance of the air flow and enter the area of the packing layers. At this time, the spraying device will evenly spray the pre-prepared absorption liquid. The waste gas and the absorption liquid will fully contact on the surface of the packing layers and begin to undergo a series of physical and chemical reactions.

For example, for waste gas containing acidic pollutants (such as sulfur dioxide, nitrogen oxides, etc.), an alkaline absorption liquid can be used. After the two come into contact, an acid-base neutralization reaction will occur, converting the pollutants into relatively harmless salt substances that dissolve in the absorption liquid. For organic waste gas, specific components in the absorption liquid will intercept the organic pollutants through adsorption, dissolution and other effects. After being fully treated by the packing layers, the gas continues to rise and passes through the demister. The demister will remove the droplets entrained in the gas to avoid secondary pollution caused by the carried droplets or affecting the operation of subsequent equipment. Finally, the purified clean gas is discharged from the air outlet at the top of the tower, realizing the effective purification of waste gas.

MAIN PERFORMANCE AND FEATURES

(I) High Purification Efficiency

The waste gas purification tower has an excellent purification effect on many common industrial waste gases, such as acidic waste gas, alkaline waste gas, organic waste gas and dusty waste gas. For different types of waste gas, by selecting appropriate absorption liquids and optimizing operating parameters, its purification efficiency can reach about 80% - 98%, which can significantly reduce the content of pollutants in waste gas and make it meet strict environmental protection emission standards, playing an important role in improving the quality of the atmospheric environment.

(II) Wide Application Range

It almost covers all fields where industrial waste gas is generated and can play a significant role in industries such as chemical industry, steel industry, power industry, printing and dyeing industry, and pharmaceutical industry. Whether it is the harmful waste gas with complex components generated in chemical production, the waste gas such as smoke and sulfur dioxide in the steel smelting process, or the odorous gas emitted by printing and dyeing factories, the waste gas purification tower can conduct targeted treatment according to the actual situation, with extremely strong versatility and meeting diverse waste gas treatment needs.

(III) Stable and Reliable Operation

The structural design of the equipment is mature, and the connections between various components are tight, which is not prone to problems such as loosening and leakage. Meanwhile, it relies on simple and stable physical and chemical principles for waste gas treatment and does not have complex and easily damaged mechanical transmission structures, reducing the risk of shutdowns caused by equipment failures. As long as the daily maintenance and operation are carried out in accordance with the specifications, it can operate stably for a long time, ensuring the continuity of industrial waste gas treatment work.

(IV) Simple and Convenient Operation

The operation interface is clear and intuitive. Operators only need to undergo simple training to master basic operations such as starting, stopping, replacing the absorption liquid and adjusting the spraying volume of the equipment. Moreover, the daily maintenance work mainly focuses on checking the operating status of various components, regularly cleaning the packing layers and demisters, and replenishing the absorption liquid. It does not require complex professional skills and cumbersome operation procedures, which is convenient for enterprises to manage and maintain.

(V) High Degree of Customization

The waste gas purification tower can be flexibly customized in multiple aspects such as the size of the tower body, the type of packing, the configuration of the spraying system and the treatment air volume according to the actual working conditions of different enterprises. For example, for enterprises with a large treatment air volume, a large purification tower with stronger treatment capacity can be customized. For waste gas with complex specific pollutant components, a more targeted combination of packing and absorption liquid can be selected to achieve the best purification effect and adapt to different usage scenarios.

(VI) Cost-Effectiveness Advantage

In terms of construction cost, compared with some high-end and technically complex waste gas treatment equipment, the waste gas purification tower has a relatively low cost, which is more suitable for the investment budgets of numerous small and medium-sized enterprises. Moreover, during the operation process, its energy consumption mainly focuses on the power consumption of the spraying device and the recycling of the absorption liquid. Through reasonable operation and optimization, the operation cost can be effectively controlled. Meanwhile, with its good purification effect, it can help enterprises avoid high fines due to excessive waste gas emissions. In the long run, it has significant cost-effectiveness advantages.
