二氧化氯消毒器，是一種水處理消毒設備。在原有基礎上，愛諾環(huán)保研制出第二代二氧化氯消毒器——新型一體化高純型二氧化氯發(fā)生器，它們具有相同工作原理，不過新型設備具有明顯優(yōu)勢特點，更為高效

二氧化氯消毒器是采用化學負壓曝氣工藝、制取以二氧化氯為主，CL2為輔的一種混合消毒劑。

二氧化氯消毒器及廣泛用于自來水、自卑井水、二次供水消毒、醫(yī)院污水處理、游泳池消毒、工業(yè)循環(huán)冷卻水和回用中水的消毒和殺菌黃總，此外還可用于造紙印染行業(yè)的漂白、工業(yè)廢水、生活污水的脫色、去臭、水產(chǎn)養(yǎng)殖廠水體消毒，屠宰行業(yè)污水處理等范圍。

二氧化氯消毒器相對于其它消毒設備來講，設備便宜，殺菌*，是目前的消毒設備。

二氧化氯是一種強氧化劑，在制造二氧化氯過程中伴生的Cl2、O3、H2O2等，同二氧化氯一樣都有有很強的氧化消毒作用。二氧化氯可以破壞細胞的酶而導致細胞死亡。

二氧化氯可以再廣泛的pH值范圍內(nèi)具有廣譜的殺菌能力，在較高的PH值時二氧化氯比氯的殺菌能力高3倍，氧化能力為自由氯的兩倍。二氧化氯由于不予氨氮等化合物作用，故其余氯比較高，消毒效果比CL2好。^[1]

二氧化氯易于揮發(fā)和爆炸，故而二氧化氯應避免氣體逸出，并控制其在空氣中的濃度小于10％和在水中的濃度小于30％，并應密閉貯存。

二氧化氯除了用于消毒外，還可以用于除臭和除色等。

二氧化氯在常溫下是黃色的氣體，具有類似CL2那樣令人不愉快的刺激性氣味在使用時投入多少是很大的一個問題，對此，我們簡單介紹以下二氧化氯消毒器的要求：

(1)二氧化氯投加量:投加量與遠水水質(zhì)和投加目的有關。一般應通過實驗確定。常用投加范圍大致如下：

①消毒：0.1~1.3mg/L;

②消毒兼除臭：0.6~1.3mg/L;

③消毒、除臭及氧化有機物、鐵、錳時1~1.5mg/L;

④投加量應保證管網(wǎng)末端有0.05mg/L的余氯。

(2)投加濃度：氣水溶液應控制在6~8mg/L。

(3)設置二氧化氯發(fā)生裝置的房間應考慮通風換氣良好。換氣次數(shù)為8~10次/L。

一種操作簡單、高轉化率、高純度、多用途、環(huán)保型化學法中、小型二氧化氯多級發(fā)生器。這種二氧化氯發(fā)生器，是由釜式反應器通過耐酸導管和水射式真空機組組成。釜式反應器采用的是兩級或多級反應器，主反應釜內(nèi)設有空氣分布器，副反應釜設置了平衡管，使反應更*，反應后的殘液可達標排放。生成的二氧化氯制得水溶液，也可以制得穩(wěn)定二氧化氯溶液。

做為一種新型的氧化劑和消毒劑，二氧化氯以其高效、廣譜、無殘留、無副產(chǎn)物的消毒能力和脫色、除臭、除異味等強氧化能力已經(jīng)成為水處理領域的*。和紫外線、臭氧、次氯酸鈉、CL2等傳統(tǒng)的消毒劑相比二氧化氯有著*的優(yōu)勢，它越來越成為業(yè)內(nèi)人士的*選擇。

Chlorine dioxide sterilizer is a kind of mixed disinfectant which USES chemical negative pressure aeration technology, the production of chlorine dioxide and CL2 as auxiliary. 
Chlorine dioxide disinfector humbled and widely used in tap water, well water, secondary sewage treatment, swimming pool water disinfection, hospital disinfection, industrial circulating cooling water and recycle water disinfection and sterilization in yellow total, moreover can also be used in the bleaching of paper printing and dyeing industry, industrial wastewater and domestic sewage of decoloring, go smelly water disinfection, aquatic plants, slaughtering industry sewage treatment, etc. 
The chlorine dioxide sterilizer is cheap, sterilizing and is the most popular sterilizing equipment for other sterilizing equipment. 
Chlorine dioxide is a powerful oxidant. Cl2, O3, H2O2, etc., which are associated with chlorine dioxide, have strong oxidation and disinfection. Chlorine dioxide can destroy the enzymes of cells and lead to cell death. 
Chlorine dioxide can have wide spectrum of bactericidal ability within a wide range of pH values, and chlorine dioxide is 3 times more sterilizing than chlorine and twice as much oxidation as free chlorine at higher pH value. Chlorine dioxide is not free of ammonia nitrogen and other compounds, so the remaining chlorine is relatively high and the disinfection effect is better than CL2. [1] 
Chlorine dioxide is easy to volatilize and explode. Therefore, chlorine dioxide should avoid gas escape and control its concentration in air less than 10% and in water concentration less than 30%, and should be sealed and stored. 
Chlorine dioxide is used for deodorization and deodorization. 
 
Chlorine dioxide is a yellow gas at room temperature, with similar CL2 as unpleasant pungent odor when use how much is a big problem, for this, we introduce the following the requirement of chlorine dioxide disinfector:

1 ~ 1.5mg/L for disinfection, deodorant and oxidizing organics, iron and manganese; 
It is necessary to ensure that residual chlorine at the end of the network is 0.05mg/L. 
(2) concentration: the gas solution should be controlled at 6 ~ 8mg/L.

At the same time, some analytical reagents are highly corrosive, and should be careful to avoid splash 
 
4.1 determination of raw material inlet flow 
4.1.1 operation procedure 
The raw material can be connected to the feed by a fixed volume container. Control the liquid level above the initial mark and close the valve of the raw material tank. When the liquid surface reaches the initial mark, start time with the stopwatch, stop the stopwatch and record time (t) when the liquid surface reaches the final mark. The volume difference between the timing time and the two marks is calculated. The measuring time of flow measurement should be over 10 min and three times on average. Calculate the flow. 
4.1.2 calculation of results 
(1) calculation: 
L1 = (V1 - V0)/t / 3600... (1) 
Type: 
L1 - raw material inlet flow, unit for liter per hour (L/h); 
V1 -- the volume shown in the final scale recorded at the time of measurement is liters (L); 
V0 -- the volume shown in the initial calibration of the measured time record is in liters (L); 
T -- the time used for the measurement is in seconds (s). 
4.2 determination of flow of outlet solution 
4.2.1 method feed 
Adjust the output of the generator to the normal production requirement, record the volume of the liquid flowing out of the time, and calculate the flow of the outlet solution 
4.2.2 instruments 
A stopwatch. 
4.2.3 operation procedure 
In a proper volume of the container, the precorrection a marker of volume, connect the generator to eliminate mouth catheter with container, open the valves, liquid level in the initial marking scale (where V0), start the stopwatch, when the liquid surface to end tag scale (V1), stop the stopwatch, write down the time (t). The measuring time of flow measurement should be above 60 s, and the average measurement is 3 times. The relative deviation is not greater than 1%. 
4.2.4 calculation of results 
The output flow L2 of the generator is calculated by formula (2) : 
L2 = (V1 - V0)/t / 3600... (2) 
Type: 
L2 -- the outlet flow of the generator, per hour (L/h); 
V1 -- the volume shown in the final scale recorded at the time of measurement is liters (L); 
V0 -- the volume shown in the initial scale recorded at the time of measurement, the unit is liters (L); 
T -- the time used for the measurement is in seconds (s). 
Production calculation 
5.1 the chlorine dioxide output Q1 is calculated by formula (3) : 
Q1 (c1 = L2/1... (3) 
Type: 
Q1 -- the production of chlorine dioxide per hour (g/h); 
L2 -- the flow of the product during normal operation of the product and the sample during the period of the output of the product is up to an hour (L/h). 
C1 -- the concentration of chlorine dioxide in the volume of the exported solution during normal operation of the generator, per liter (mg/L). 
5.2 effective chlorine yield Q2 is calculated by formula (4) : 
Q2 = L2 times (2.63 times c1 + c2) / 1000... (4) 
Type: 
Q2 - effective chlorine production per hour (g/h). 
L2 -- during normal operation of the product, the flow rate of the outlet solution of the sample during the same period will be increased per hour (L/h). 
C1 -- the concentration of chlorine dioxide measured in the outlet solution during normal operation of the generator is per liter per liter (mg/L). 
C2 -- the concentration of CL2 measured in the outlet solution during normal operation of the generator, per liter (mg/L); 
2.63 - chlorine dioxide is converted into CL2 coefficient.

The quality ratio of chlorine dioxide and CL2 is calculated by equation (5) : 
R = c1 / c2... (5) 
Type: 
C1 -- the concentration of chlorine dioxide measured in the outlet solution during normal operation of the generator is per liter per liter (mg/L). 
C2 -- the concentration of CL2 measured in the outlet solution during normal operation of the generator, per liter (mg/L);
