The desulfurization tower deduster's SO2 absorption and purification process handles low-concentration SO2 flue gas, with a considerable volume of flue gas. It requires continuous and effective purification of the flue gas within a short time. Therefore, the chemical reactions involving SO2 should be fast reactions, with high conversion coefficients within the membrane. As the reactions occur within the membrane, it is more suitable to use an absorption tower with a gas phase as the continuous phase, high turbulence, and a large interfacial area for both desulfurization and dedusting towers.

The SO2 emissions from power plants are of great significance in improving the air environmental quality in our country. However, it is easy to encounter structural phenomena at the bottom of the flue gas desulfurization tower, which can affect the smooth implementation of the desulfurization process.

1. Clean the bottom scale of the desulfurization tower

Firstly, clean the dirt at the bottom of the desulfurization tower! Add the cleaning agent to the circulating liquid at the bottom, and use the circulating pump at the bottom of the desulfurization tower to circulate and clean, ensuring the dirt at the bottom of the tower is thoroughly cleaned, and the bottom of the desulfurization tower's drainage pipe is not buried in the scale layer! The cleaning of the scale at the bottom of the desulfurization tower is done in three steps.

2. Cleaning and unblocking of the drain pipes at the bottom of the separator tubes

After the dirt at the bottom of the desulfurization tower is cleaned, proceed with the cleaning and unblocking of the drainage pipes at the bottom of the separator tubes in the separator! First, open the manhole under the pressure of RS2, and while all equipment in the system remains operational, fully utilize the robotic automatic cleaning technology. Control the crawling mechanism (ensuring the cleaning of each separator tube) and pull the flexible polyvinyl chloride spray pipe, making a full circle around the desulfurization tower. Ensure the cleaning mechanism aligns with each separator tube of the tower, with accurate spray positions. Timely spray the cleaning agent, maintaining the process continuously, and monitor the cleaning effect and any potential issues!

3. High-pressure water cleaning is a popular physical cleaning method for desulfurization towers, yielding significant results after cleaning.
