1、制藥廢氣---顆粒污染物:廢氣通過管道系統(tǒng)送至布袋除塵器內(nèi),大顆粒的污染物依靠重力的作用沉積到除塵器底部,然后小顆粒的污染物依靠布袋的過濾作用,被截留在布袋的外表面,積累到一定的時間后,反吹灰系統(tǒng)自動打開,從而將布袋表面的灰塵,振打下來,這樣反復(fù)操作。潔凈的空氣通過風(fēng)機(jī)增壓后外排至室外大氣環(huán)境響水縣濱??h印刷廢氣處理效果好。
2、制藥廢氣----酸堿廢氣:廢氣通過管道系統(tǒng)送至噴淋洗滌塔,廢氣自下而上通過噴淋塔,堿(酸)液自上部噴淋而下,經(jīng)過逆洗后,氣體中的酸性或堿性物質(zhì)被中和而溶解在噴淋液中,達(dá)到凈化的目的。凈化后的氣體被除去水霧后再通過風(fēng)機(jī)增壓后外排至室外大氣環(huán)境。
3、制藥廢氣----二噁英或重金屬:因制藥廢氣物焚燒后產(chǎn)生極少量的二噁英或重金屬廢氣,只是在主要工藝提升排放指標(biāo)時使用,且二噁英和重金屬含量極低,所以一般是采用活性炭吸附的方法去除此類污染物。響水縣濱??h印刷廢氣處理效果好

Waste gas treatment in Jiangyin printing shop, the main nitrogen oxides in the atmosphere are nitric oxide (NO) and nitrogen dioxide (NO2) in the nitrogen oxides of the industrial waste gas treatment equipment. The determination of nitrogen oxides in the atmosphere first oxidizing nitric oxide with oxidant (such as chromium oxide, three) to nitrogen dioxide, then measured and measured the concentration of nitrogen oxides in the air with the concentration of nitrogen dioxide.
Introduction of nitrogen oxides in industrial waste gas treatment
China's industrial waste gas treatment is specified by the naphthyl ethylenediamine hydrochloride colorimetric method as a standard method for the determination of nitrogen oxides in the atmosphere. The principle is to absorb nitrogen dioxide in a solution prepared by glacial acetic acid, p-Aminobenzene Sulfonic Acid and naphthalene ethylenediamine hydrochloride. Nitrogen dioxide is used to form nitrite ion in the solution and reacts with p-Aminobenzene Sulfonic Acid, and then the azo dye is coupled with naphthalene ethylenediamine hydrochloric acid, orange rose red, and colorimetric quantitative. The time absorbed liquid was 5mL and the sampling speed was 300mL/min. When the absorption liquid is slightly red, the sampling time is recorded and the sampling volume is calculated. The standard sodium nitrite is used to prepare the equivalent standard solution of various concentrations. It can also be diluted into the standard gas of all kinds of concentration by the method of dynamic distribution of nitrogen dioxide permeable pipe and then absorbed into the absorption liquid to show the color. At the same time, the calibration value of the reagent blank sample was measured, and the standard colorimetric curve after the correction of the reagent blank sample was used to calculate the microgram number of Bs per unit absorbance equivalent to nitrogen dioxide. The determination method of air sample is the same as that of standard gas. The concentrations of NOx (calculated as NO2, mg/m3) were measured respectively.
NO2=Bs (A-A0) / (0.76V)
Formula A - -- absorbance of sample solution;
A0 - -- absorbance of reagent blank solution;
V -- -- the volume of air sample under standard condition, L;
0.76 -- -- the coefficient of NO2 gas converted to NO2 in solution;
Bs - -- - Computing factor.
The continuous automatic monitoring instruments for nitrogen oxides include dynamic Kulun instruments and chemiluminescent detectors.
