煙氣脫硫設(shè)備需要注意哪些事項(xiàng)呢?

煙氣脫硫是工業(yè)大規(guī)模應(yīng)用的有效脫硫方法。按照硫化物吸收劑及副產(chǎn)品的形態(tài),脫硫技術(shù)可分為干法、半干法和濕法三種。那么,煙氣脫硫設(shè)備需要注意哪些事項(xiàng)呢?

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?
煙氣脫硫設(shè)備裝置有害因素
Harmful factors of flue gas desulfurization equipment
1.設(shè)備、設(shè)施缺陷:脫硫吸收塔工作條件惡劣,既有煙氣沖刷,又有SO2與石灰石漿液化學(xué)反應(yīng)。石灰石漿液的洗刷造成煙氣脫硫吸收塔溫度、腐蝕、磨損綜合作用逐步損壞。石灰石漿液系統(tǒng)、管道、閥門、漿液循環(huán)泵、漿液輸送泵都會受到石灰石漿液的腐蝕和磨損,然而造成煙氣脫硫塔損壞、燒毀。
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、灼傷:石灰石漿液輸送至吸收塔,若管道、閥門、泵泄漏造成漿液泄漏。易燙傷人體、污染環(huán)境;煙氣系統(tǒng)煙道、設(shè)備等不嚴(yán)密或引風(fēng)機(jī)故障造成煙氣泄漏,煙氣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.吸收塔入口煙道及出口至擋板的煙道,煙氣溫度較低。煙氣含濕量較大,容易對煙道產(chǎn)生腐蝕,需進(jìn)行防腐處理,對重點(diǎn)部位可考慮安裝攝像頭或者定期進(jìn)行巡檢,對煙囪、煙道的受腐蝕情況隨時(shí)進(jìn)行監(jiān)控記錄。
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、粉塵等:石灰石粉在運(yùn)輸及裝卸過程中會存在大量的石灰石粉塵,操作人員如個(gè)人防護(hù)不完善,長期操作會使操作人員健康受到危害。制漿系統(tǒng)管道如泄漏噴濺就會造成操作人員身體的危害。
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.
以上就是本小編給大家介紹的煙氣脫硫設(shè)備操作運(yùn)行前的注意事項(xiàng),掌握好煙氣脫硫設(shè)備注意事項(xiàng)能夠使脫硫設(shè)備更好的脫硫效果。
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.
