生物脫硫工藝流程如下:脫硫系統(tǒng)主要由煙氣系統(tǒng)、吸收氧化系統(tǒng)、石灰石/石灰漿制備系統(tǒng)、副產(chǎn)品處理系統(tǒng)、廢水處理系統(tǒng)、公用工程系統(tǒng)(工藝水、壓縮空氣、事故漿液箱系統(tǒng)等組成。)和電氣控制系統(tǒng)。

The process flow of biological desulfurization is as follows: the desulfurization system mainly consists of a flue gas system, an absorption oxidation system, a limestone/lime slurry preparation system, a by-product treatment system, a wastewater treatment system, a utility system (consisting of process water, compressed air, accident slurry tank system, etc.), and an electrical control system.

石灰石-石膏濕法脫硫工藝鍋爐引風(fēng)機排出的原煙氣由增壓風(fēng)機引入脫硫系統(tǒng)，經(jīng)GGH(氣體加熱器)換熱后進(jìn)入吸收塔。

The raw flue gas discharged from the induced draft fan of the limestone gypsum wet desulfurization process boiler is introduced into the desulfurization system by the booster fan, and after heat exchange by the GGH (gas heater), it enters the absorption tower.

鍋爐引風(fēng)機排出的原煙氣由增壓風(fēng)機引入脫硫系統(tǒng)，經(jīng)GGH(氣體加熱器)換熱后進(jìn)入吸收塔。生物脫硫工藝在吸收塔內(nèi)，原煙氣自下而上通過塔體，由噴霧系統(tǒng)噴出的霧狀石灰石漿液逆流混合。脫硫后的凈煙氣由噴淋系統(tǒng)上部的除霧器從吸收塔除去，然后進(jìn)入GGH，經(jīng)GGH換熱升溫后通過煙囪排出

The raw flue gas discharged from the boiler induced draft fan is introduced into the desulfurization system by the booster fan, and after heat exchange by the GGH (gas heater), it enters the absorption tower. The biological desulfurization process is in the absorption tower, where the original flue gas passes through the tower body from bottom to top, and the atomized limestone slurry sprayed by the spray system is mixed countercurrent. The purified flue gas after desulfurization is removed from the absorption tower by the demister on the upper part of the spray system, and then enters the GGH. After heat exchange and temperature rise in the GGH, it is discharged through the chimney

霧化脫硫除塵技術(shù)主要研究煙塵、二氧化硫等有害物質(zhì)的化學(xué)成分和物流運動特性，利用流體力學(xué)、空氣動力學(xué)、化學(xué)、力學(xué)等。

The atomization desulfurization and dust removal technology mainly studies the chemical composition and logistics characteristics of harmful substances such as smoke and sulfur dioxide, using fluid mechanics, aerodynamics, chemistry, mechanics, etc.

它是集固體噴霧技術(shù)、霧化洗滌技術(shù)、冷凝霧化技術(shù)、沖擊湍流技術(shù)、過濾吸收技術(shù)、除霧分離技術(shù)等多科學(xué)、多過程的環(huán)保技術(shù)。生物脫硫工藝該技術(shù)的主要特點是壽命長、效率高、阻力低、節(jié)能、占地面積小、造價低、運行費用低、維護(hù)率低、管理方便、灰水閉路循環(huán)、無二次廢水和粉塵污染。

It is a multi science and multi process environmental protection technology integrating solid spray technology, atomization washing technology, condensation atomization technology, impact turbulence technology, filtration absorption technology, demisting and separation technology, etc. The main characteristics of biological desulfurization technology are long service life, high efficiency, low resistance, energy saving, small footprint, low cost, low operating expenses, low maintenance rate, convenient management, closed-loop circulation of grey water, and no secondary wastewater and dust pollution.

處理后煙塵指標(biāo)低于國家環(huán)保排放標(biāo)準(zhǔn)，符合國家鼓勵環(huán)保產(chǎn)業(yè)發(fā)展的政策通過集除塵、脫硫、脫硝、除霧于一體，達(dá)到控制和凈化大氣污染的目的。

The smoke and dust indicators after treatment are lower than the national environmental emission standards, which is in line with the policy of encouraging the development of the environmental protection industry. By integrating dust removal, desulfurization, denitrification, and defogging, the goal of controlling and purifying air pollution is achieved.

對于減少酸雨、二氧化硫、氮氧化物、氟化物、粉塵、可吸入懸浮顆粒物等有害物質(zhì)具有巨大的環(huán)境、社會和經(jīng)濟(jì)效益，也具有良好的市場前景。

Reducing harmful substances such as acid rain, sulfur dioxide, nitrogen oxides, fluorides, dust, and inhalable suspended particles has enormous environmental, social, and economic benefits, as well as good market prospects.
