Description
Acid alkali amine scrubber working principle
The amine scrubber is suitable for the acid mist treatment scheme. Acid mist exhaust gas is collected by suction hood or other gas collecting device and then passes through PP air duct. Under the action of an anti-corrosion centrifugal fan at the end, acid mist exhaust gas is drawn into a water scrubber, the acid mist exhaust gas flows upstream in the purification tower, the wind speed becomes slow, and the acid-base neutralization reaction takes place in the packing layer with a large specific surface area and a particular concentration of sodium hydroxide alkali solution for absorption, and then passes through the top of the tower to remove mist. The water mist is removed from the layer, and after exiting the tower, it passes through the anti-corrosion centrifugal fan. Under the action of the centrifugal fan, the gas is sent to the chimney system, and then the treated clean gas is discharged at the height of 15 meters.
Features
The amine scrubber has a reasonable structure design, using a new type of multi-faceted hollow ball as the filler, the flow resistance of the acid mist exhaust gas in the water scrubber is small, and the specific surface area of the filler is large, the chemical reaction is perfect, the gas-liquid ratio is reasonable, and the absorption and purification High efficiency, corrosion resistance, good aging resistance, easy installation, and maintenance, etc.
Strong ability to handle acid mist
The amine scrubber is designed with a large cross-sectional area to ensure that the empty tower flow rate meets the design requirements;
High processing efficiency
The acid mist stays in the tower for a long time, ensuring the time required for acid-base neutralization and high purification efficiency;
Simple structure
The amine scrubber adopts a backwash structure, which is suitable for small space installation and occupies a small area;
Stable operation
The amine scrubber is simple in structure, designed with maintenance and inspection ports, automatic control, and stable operation;
Low system resistance
The pressure drop of the amine scrubber gas passing through the packing layer per unit height is small;
Industry application
The amine scrubber produced by XICHENG EP LTD can be used in different industries, including acid mist emitted by different production processes, metal surface treatment, hardware pickling, anodizing, glass panel etching, laboratory fume hood, petrochemical industry Reactor, biopharmaceutical industry, power plant, etc. The following are several application descriptions of amine scrubber manufactured by XICHENG EP LTD.
Installation method
- Basic positioning of amine scrubber to determine the direction of exhaust gas inlet,
- Install the front exhaust pipe and connect it to the exhaust inlet,
- The fan is installed at the back end, and the method of damaging pressure extraction is adopted,
- Chimney installation, installed at the rear of the fan, blowing from the fan into the chimney,
- The drug-device is installed, and the dosing port is passed into the water tank of the amine scrubber,
- The electric control device is installed, and the circulating water pump, fan, and dosing device of the amine scrubber are controlled by the electric control panel,
- Installation of testing port and testing platform,
- Test the machine, and adjust the air volume and flow rate by adjusting the opening of the front air valve.
What kind of waste gas can the wet scrubber for waste gas purification treat?
The amine scrubber is widely used in the washing and purification of NOX, SO2, H2SO4, HCl, HF, SIF4, CO2, and other toxic and harmful gases generated in the chemical, electroplating, hardware, electrical, pharmaceutical, printing, and dyeing, telecommunications, and other mechanical processing industries; It can also be applied to the deodorization treatment of ammonia, hydrogen sulfide, phenolic, formaldehyde, methanol, amines, and other malodorous substances; the purification area of acid mist exhaust gas depends on the treatment volume, and the neutralization and removal effect is 95%; the discharge port is less than 10PPM. Fans and pumps can be flexibly designed and laid out according to the user’s site, featuring convenient maintenance, compact structure, and a small footprint.
