[0002] The production of sulfur paste generates a large amount of waste gas containing harmful components such as hydrogen sulfide and sulfur dioxide. These gases have an irritating odor and are harmful to the environment and human health, and must be effectively treated before being discharged. Traditional waste gas treatment methods often employ simple water washing or single adsorption processes, which suffer from low purification efficiency, incomplete treatment, and difficulty in handling high-concentration or complex waste gases. Furthermore, some washing equipment has an unreasonable structural design, lacking effective gas-liquid contact mechanisms and multi-stage purification functions, resulting in unstable treatment effects. Moreover, the equipment is susceptible to corrosion from acidic gases during long-term operation, leading to high maintenance costs.

[0003] In existing technologies, traditional waste gas treatment devices generally suffer from problems such as low purification efficiency, incomplete filtration, and easy corrosion of equipment when treating sulfur-containing waste gas generated during the production of sulfur paste. Some scrubbing towers have simple structures and lack multi-stage filtration and precise flow control, resulting in poor removal of harmful gases such as hydrogen sulfide and sulfur dioxide. At the same time, long-term contact with acidic gases and scrubbing liquids can easily cause corrosion of the inner wall of the equipment, affecting operational stability and service life.

[0014] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0015] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0016] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0017] Example Reference Figures 1-4 This is an embodiment of the present invention, which provides a sulfur paste production waste gas scrubbing tower, comprising, The main body of the storage tank 100 is used to contain the washing liquid and serve as the main reaction chamber for waste gas treatment; The exhaust mechanism 200 includes a drive assembly 201 and a filter assembly 202; The drive assembly 201 includes an air pump 2011 and an air supply pipe 2012. The air pump 2011 is connected to the air inlet of the storage tank body 100 through the air supply pipe 2012, and is used to draw the waste gas generated during the sulfur paste production process into the scrubbing tower. The filter assembly 202 includes a filter screen 2021, a control valve 2022, a filter 2023, and a water spray pipe 2024. The filter screen 2021 is located in the channel through which the exhaust gas enters the main body 100 of the storage tank and is used to intercept particulate matter. The control valve 2022 is located on the gas delivery pipe 2012 and is used to regulate the exhaust gas flow rate. The filter 2023 is located inside the main body 100 of the storage tank and is used to perform multi-stage chemical or physical adsorption purification of the exhaust gas. The water spray pipe 2024 is located at the top of the main body 100 of the storage tank and is used to spray washing liquid into the tower to achieve full gas-liquid contact to remove harmful gases.

[0018] Specifically, the inner wall of the storage tank body 100 is equipped with an anti-corrosion coating, which can resist the corrosion of acidic washing liquid and sulfur-containing waste gas, and extend the service life of the equipment.

[0019] It should be noted that the anti-corrosion coating on the inner wall of the storage tank body 100 is made of epoxy resin or polytetrafluoroethylene material, which can effectively prevent tank corrosion, perforation or structural deterioration under long-term contact with acidic washing liquid and corrosive sulfur-containing waste gas, significantly extending the service life and operational safety of the equipment.

[0020] Specifically, the 2021 filter has a multi-layer stainless steel mesh structure with pore sizes decreasing from the outside to the inside, enabling graded filtration of particles of different sizes.

[0021] It should be noted that the 2021 filter uses a multi-layer stainless steel mesh structure. The outer layer has a larger pore size to intercept large particles of impurities, while the inner layer has a gradually decreasing pore size to capture fine dust, forming a gradient filtration. This not only improves filtration efficiency but also reduces the risk of clogging of a single-layer filter, making it easier for later maintenance and cleaning.

[0022] Specifically, the control valve 2022 is an electric regulating valve that can automatically adjust its opening degree through an external controller to achieve precise control of the exhaust gas flow rate.

[0023] It should be noted that the control valve 2022 is an electric regulating valve, which can automatically adjust the valve opening through a PLC or remote controller, dynamically adjust the airflow rate according to the amount of exhaust gas generated, realize intelligent flow control, and improve the stability and energy efficiency of the system operation.

[0024] Specifically, the filter 2023 is filled with activated carbon or alkaline adsorption material to efficiently remove harmful components such as hydrogen sulfide and sulfur dioxide from the exhaust gas.

[0025] It should be noted that the activated carbon or alkaline adsorbent material such as calcium hydroxide or sodium carbonate particles filled inside the filter 2023 can physically adsorb or neutralize acidic gases such as hydrogen sulfide and sulfur dioxide in the exhaust gas, achieving efficient purification and ensuring that the emitted gas meets environmental protection standards.

[0026] Specifically, the water spray pipe 2024 is equipped with multiple atomizing nozzles, which can atomize the washing liquid into fine droplets, increase the contact area with the exhaust gas, and improve washing efficiency.

[0027] It should be noted that the multiple atomizing nozzles installed on the water spray pipe 2024 can atomize the washing liquid, such as alkali or water, into micron-sized droplets, greatly increasing the gas-liquid contact surface area, promoting the dissolution and reaction of harmful gases, and significantly improving the desulfurization efficiency and purification effect of the scrubbing tower.

[0028] In use, first inject an appropriate amount of washing liquid, such as an alkaline solution or clean water, into the main body 100 of the storage tank, and check whether the connections of each component are sealed reliably. Start the air pump 2011, and draw the sulfur-containing waste gas generated during the sulfur paste production process into the washing tower system through the air supply pipe 2012. Driven by the air pump, the waste gas enters the air intake channel and first passes through the filter screen 2021. Its multi-layer stainless steel mesh structure has a progressively smaller aperture from the outside to the inside, which can effectively intercept dust, particulate matter, and impurities carried in the waste gas, achieving preliminary physical filtration. The control valve 2022 on the air supply pipe 2012 can be adjusted according to the actual waste gas flow requirements. If an electric regulating valve is used, the opening can be automatically controlled by an external controller to achieve precise airflow management. The purified waste gas enters the main body 100 of the storage tank. Inside the 00 section, the water spray pipe 2024 is activated, and multiple atomizing nozzles on it evenly atomize the washing liquid and spray it downwards, forming a high-density liquid mist zone. This allows for full contact between the gas and liquid, and harmful gases such as hydrogen sulfide and sulfur dioxide in the exhaust gas undergo dissolution or neutralization reactions with the washing liquid, achieving efficient removal. Subsequently, the gas continues to rise into the filter 2023 area, where activated carbon or alkaline adsorption materials further adsorb or chemically treat residual harmful components, completing multi-stage purification. The treated gas that meets the standards is discharged from the top of the tower, while the washing liquid carrying pollutants settles at the bottom of the tank, which can be periodically discharged or recycled. Throughout the process, the anti-corrosion coating on the inner wall of the storage tank 100 effectively resists corrosion from the acidic environment, ensuring long-term stable operation of the equipment.

[0029] In summary, by setting up a coordinated structure between the storage tank body 100 and the exhaust mechanism 200, efficient washing and purification of waste gas is achieved. The filter screen 2021 filters particulate matter in stages, the control valve 2022 precisely regulates the airflow, the water spray pipe 2024 atomizes the washing liquid to enhance gas-liquid contact, and the filter 2023 deeply removes harmful gases. The overall device has high purification efficiency, stable operation, and is corrosion-resistant and durable. It effectively solves the problems of incomplete waste gas treatment and easy equipment corrosion in the sulfur paste production process, and improves environmental performance and service life.
