脫硫塔中（zhōng）的設備主要包括攪拌器，氧化風管，噴淋管，除（chú）霧器，其他方案包括擋板或均勻分布（bù）地板。位（wèi）於脫硫塔底部的攪拌器主要起到泥漿攪動的作用，防止石膏等顆粒的（de）沉積。

氧化管道主要是將空氣（qì）注入塔內的泥（ní）漿（jiāng）池（chí）中，將亞硫酸鹽氧化成硫酸鹽，配套設備是氧化風扇。管道是將漿料（liào）通過循環泵送（sòng）到脫硫塔漿池區，通過噴嘴霧化並分散，然後吸收煙道氣中的SO2氣體。除霧器的主要作用是去除煙道氣中攜帶的液滴，即去除水的作用（yòng）。

脫硫劑的表麵具有活性、催化氧化的作用之外，這種設備（bèi）還（hái）可以直接地促進SO2反應，使CaCO3的（de）溶解加快，促（cù）進CaSO3向CaSO4的快速氧（yǎng）化，使（shǐ）CaSO4的沉積加強，並且還可以讓液氣比，鈣的比例（lì）降（jiàng）低，去硫，減少水的蒸騰作（zuò）用。

當煙氣入口SO2濃度高於（yú）計劃值時，吸收塔（tǎ）反應池中的PH值將降低，並（bìng）且（qiě）當需要更大（dà）的Ca / S比時（shí），無需擴展CaCO3即可迅速溶（róng）解CaCO3。加（jiā）入鈣離子使漿料（liào）的PH值保持在正常範圍內，對pH值有一（yī）定的緩衝（chōng）作（zuò）用。

The equipment in the desulfurization tower mainly includes agitator, oxidation air pipe, spray pipe and demister. Other schemes include baffle or evenly distributed floor. The agitator at the bottom of the desulfurization tower mainly plays the role of slurry stirring to prevent the deposition of gypsum and other particles.

The oxidation pipeline mainly injects air into the mud pit in the tower to oxidize sulfite into sulfate. The supporting equipment is oxidation fan. The pipeline sends the slurry to the slurry tank area of the desulfurization tower through the circulating pump, atomizes and disperses through the nozzle, and then absorbs the SO2 gas in the flue gas. The main function of demister is to remove the droplets carried in flue gas, that is, to remove water.

In addition to the active and catalytic oxidation on the surface of desulfurizer, this equipment can also directly promote the SO2 reaction, accelerate the dissolution of CaCO3, promote the rapid oxidation of CaSO3 to CaSO4, strengthen the deposition of CaSO4, reduce the liquid-gas ratio and calcium ratio, remove sulfur and reduce the transpiration of water.

When the SO2 concentration at the flue gas inlet is higher than the planned value, the pH value in the reaction tank of the absorption tower will decrease, and when a larger Ca / S ratio is required, CaCO3 can be dissolved quickly without expanding CaCO3. Adding calcium ion keeps the pH value of the slurry within the normal range and has a certain buffer effect on the pH value.
