Profile Aluminium Anodizing Machine Eco Friendly Electrode Coating Vertical Design

Introduce the technical scheme of exhaust gas for aluminum profile anodizing equipment:
I. Overview: This waste gas treatment tower is mainly used for acid-alkaline gas before anodizing.
The working environment of the workshop will also pollute the surrounding environment and affect the health of the staff. According to the relevant national environmental protection regulations, the gas containing the pollutants needs to be treated and discharged before reaching the standard. To this end, the company will use different treatment methods for different exhaust gases based on the actual situation on site and the relevant experience of the company for exhaust gas treatment for many years. The acid mist gas is absorbed by sodium hydroxide, and the alkali mist gas is absorbed by nitric acid. The wastewater produced will enter the wastewater treatment station for treatment.

Second, the design basis:
The design, construction and installation of this project strictly implement the national professional technical norms and standards.

The main norms and standards are as follows:
1. Technical requirements and information provided by the buyer;
2. The Environmental Protection Law of the People's Republic of China;
3. "Environmental Air Quality Standards" GB3095-1996;
4. "Electroplating Pollutant Emission Standards" GB21900-2008;
5. "Exhaust sampling point setting and sampling method" GB/T16157;
6, the main draft pipe design wind speed according to 15 m / s design.
7. The measurement of the ventilation effect of the production line will be measured according to the wind speed of 1 m/s (measured at a distance of 5 cm from the hood of each slot), and the area of ​​the air outlet of the draft hood should not be less than 50% of the area of ​​the groove.

Third, the processing technology:
1. Treatment method: The cleaning process of the exhaust gas is completed by using the detergent tower lotion and absorption method. According to the actual situation of the user side and the requirements of the user side, only the pre-treatment area needs to be exhausted (a total of one exhaust gas treatment tower).
2. Process: exhaust gas → gas collecting hood → air duct → centrifugal exhaust fan → packed tower and absorption system → discharge.
3. Working principle: The exhaust gas generated in the production process is pumped into the purification tower studio through the exhaust hood and air duct on the production line, and sent to the purification tower processor through the non-equal speed returning air supply system. After the acid-base gas is sprayed, it passes through the filler chips composed of the most novel multi-faceted hollow ball filler, and then sprayed through 1-2 channels to make the gas-liquid two-phase large-area contact and absorption, resulting in a neutralization reaction. The treated gas is then degassed by gas-water separation and then discharged into the atmosphere through a discharge pipe, and the gas emitted at this time is much lower than the national emission standard.
