小編給大家引見了脫硫過程中常用脫硫劑的類型及特性，但是僅僅知道這些就夠了嗎?當(dāng)然不是的，在脫硫過程中或多或少還會(huì)呈現(xiàn)問題，這就懇求脫硫人員在實(shí)施脫硫前，全 面了解脫硫過程的一些留意事項(xiàng)，避免呈現(xiàn)問題。
Xiaobian introduces the types and characteristics of commonly used desulfurizers in the desulfurization process, but is it enough to know these? Of course not, there will be more or less problems in the desulfurization process, so we implore desulfurization personnel to fully understand some matters needing attention in the desulfurization process before implementing desulfurization, so as to avoid problems.
(1)進(jìn)、出粗脫硫系統(tǒng)時(shí)煤氣粉塵、焦油要少，煤氣得到凈化處置。往常較為常用的多為在濕法脫硫系統(tǒng)的進(jìn)出口增加靜電除塵器，將煤氣中的塵埃、焦油類物質(zhì)中止捕集凈化煤氣，減少雜質(zhì)對(duì)加壓風(fēng)機(jī)、脫硫溶液系統(tǒng)的影響。
(1) When entering and leaving the crude desulfurization system, the gas dust and tar should be less, and the gas should be purified. Usually more commonly used is to add electrostatic precipitator at the inlet and outlet of the wet desulfurization system to stop the collection of dust and tar in the gas and purify the gas, so as to reduce the influence of impurities on the pressurized fan and desulfurization solution system.
(2)為了安穩(wěn)脫硫液成份，減少副鹽含量，將硫泡沫中止先機(jī)械分別后間歇熔硫，盡可能減少對(duì)脫硫液中止加熱升溫。
(2) in order to stabilize the components of desulphurizing liquid and reduce the content of secondary salt, the sulfur foam should be stopped before mechanical treatment and then intermittent sulphur melting, so as to reduce the heating up of desulphurizing liquid as far as possible.
在往常大多數(shù)廠家中的變脫系統(tǒng)都是變脫后脫硫液靠本身壓力直接進(jìn)入放射器，這種規(guī)劃在工作上不會(huì)呈現(xiàn)大問題，但脫硫液質(zhì)量及硫泡沫生成不是很好。變脫系統(tǒng)的規(guī)劃中應(yīng)思索增設(shè)富液槽，將脫硫液降至常壓后，再用泵保送至再生槽，在富液槽中一方面釋放很多的CO2氣體，另一方面，保證脫硫液在系統(tǒng)中滿意的停留時(shí)間，便于構(gòu)成豐厚的硫泡沫層。
In most of the manufacturers, the degaging system of the majority of the plants is deactivated, and the desulfurizing liquid will directly enter the radiator by its own pressure. This plan will not present great problems in the work, but the quality of the desulfurizing liquid and the formation of sulfur foam are not very good. In the planning of the disconnecting system, we should think about adding rich liquid tanks, lowering the desulfurizing solution to atmospheric pressure, and then pump it to the regeneration tank, releasing a lot of CO2 gas on the one hand. On the other hand, it ensures the satisfactory residence time of the desulfurizing liquid in the system, and is easy to form a thick sulfur foam layer.
脫硫技術(shù)有很多種，每種脫硫技術(shù)在實(shí)施過程中需求留意的點(diǎn)也是不一樣，這就懇求大家在實(shí)施脫硫之前一定要做足了功課，避免不測(cè)的發(fā)作。
There are many kinds of desulfurization technologies, and the points that need to be paid attention to in the implementation process of each desulfurization technology are also different, so we implore everyone to do enough homework before the implementation of desulfurization to avoid unexpected attacks.
