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?

烟气脱硫设备装置有害因素

Harmful factors of flue gas desulfurization equipment

1.设备、设施缺陷：脱硫吸收塔工作条件恶劣，既有烟气冲刷，又有SO2与石灰石浆液化学反应。石灰石浆液的洗刷造成烟气脱硫吸收塔温度、腐蚀、磨损综合作用逐步损坏。石灰石浆液系统、管道、阀门、浆液循环泵、浆液输送泵都会受到石灰石浆液的腐蚀和磨损，然而造成烟气脱硫塔损坏、烧毁。

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.中毒、灼伤：石灰石浆液输送至吸收塔，若管道、阀门、泵泄漏造成浆液泄漏。易烫伤人体、污染环境；烟气系统烟道、设备等不严密或引风机故障造成烟气泄漏，烟气中含有大量的一氧化碳。二氧化碳和少量的氮氧化物、二氧化硫等。

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.吸收塔入口烟道及出口至挡板的烟道，烟气温度较低。烟气含湿量较大，容易对烟道产生腐蚀，需进行防腐处理，对重点部位可考虑安装摄像头或者定期进行巡检，对烟囱、烟道的受腐蚀情况随时进行监控记录。

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.噪音、粉尘等：石灰石粉在运输及装卸过程中会存在大量的石灰石粉尘，操作人员如个人防护不完善，长期操作会使操作人员健康受到危害。制浆系统管道如泄漏喷溅就会造成操作人员身体的危害。

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.
