Flue gas desulfurization is an effective desulfurization method for large-scale industrial application. According to the form of sulfide absorbent and by-products, desulfurization technology can be divided into dry method, semi dry method and wet method. So, what should be paid attention to in the flue gas desulfurization equipment?

Harmful factors of flue gas desulfurization equipment
1. Defects of equipment and facilities: the working conditions of desulfurization absorption tower are poor, including flue gas scouring and chemical reaction between SO2 and limestone slurry. The washing of limestone slurry causes the comprehensive effects of temperature, corrosion and wear of FGD absorption tower to be gradually damaged. Limestone slurry system, pipeline, valve, slurry circulating pump and slurry delivery pump will be corroded and worn by limestone slurry, but the flue gas desulfurization tower will be damaged and burnt.
2. Poisoning and burning: limestone slurry is transported to the absorption tower, and slurry leakage is caused by leakage of pipes, valves and pumps. Easy to burn the human body and pollute the environment; The flue gas leakage is caused by the loose flue and equipment of the flue gas system or the failure of the induced draft fan, and the flue gas contains a large amount of carbon monoxide. Carbon dioxide and a small amount of nitrogen oxides, sulfur dioxide, etc.
3. The flue gas temperature at the inlet of the absorption tower and the flue gas from the outlet to the baffle is low. The moisture content of flue gas is large and it is easy to corrode the flue gas. Therefore, anti-corrosion treatment is required. For key parts, cameras can be installed or regular patrol inspection can be conducted to monitor and record the corrosion of the chimney and flue gas at any time.
4. Noise, dust, etc.: there will be a large amount of limestone dust during the transportation and loading and unloading of limestone powder. If the personal protection of operators is not perfect, long-term operation will endanger the health of operators. Leakage and splashing of slurry system pipeline will cause harm to operators.
The above are the precautions before the operation of the flue gas desulfurization equipment introduced to you in this small edition. Mastering the precautions of the flue gas desulfurization equipment can make the desulfurization equipment better desulfurization effect.
The above is the detailed introduction of dry desulfurization for you. I hope it will help you. If you have any questions, please contact us. We will provide you with services in a professional manner https://www.hneee.net
