Description
XICHENG EP LTD specializes in the production of acid fume scrubbers, which can be used to treat acid mist waste gas generated in industrial production workshops. In the working principle of packing absorption, the acid fume scrubber body adopts a vertical structure, and the acid mist exhaust gas enters from the lower part of the tower body, and passes through the packing layer, spray layer, and defogging layer from the bottom to top and then is discharged from the top exhaust port. The HCl gas scrubber is made of a PP sheet reel after forming and welding. The body is designed with a circulating water tank, an acid mist inlet, a packing layer, a packing bearing grille, a spray layer, a demisting layer, an exhaust gas outlet, and a discharge port, Filling inlet, observation window, etc.
Working principle
The acid fume scrubber is suitable for an 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 exhaust gas purification in the formaldehyde scrubber, the acid mist exhaust gas flows upstream in the scrubber, and 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 certain 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 a height of 15 meters.
Features
The acid fume 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 HCL gas 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 acid fume 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 acid fume scrubber adopts a backwash structure, which is suitable for small space installation and occupies a small area;
- Stable operation
The acid fume scrubber is simple in structure, designed with maintenance and inspection ports, automatic control, and stable operation;
- Low system resistance
The pressure drop of the acid fume scrubber gas passing through the packing layer per unit height is small;
product structure
The acid fume scrubber body part contains: a water storage tank, packing layer, spray layer, defogging layer, observation window, base, etc.;
The circulating water part contains a vertical circulating water pump, UPVC circulating water pipeline, PP spiral nozzle, water tank level control, floating ball valve, etc.; The dosing system includes PH online detector, dosing metering pump, dosing mixing barrel, etc.
