Acid alkali waste gas treatment equipment in electroplating plant

Tianlu Environmental ProtectionAcid alkali waste gas treatment equipment in electroplating plantThere are many methods for treating electroplating waste gas, among which wet washing method is widely used and the effect is also very stable.

1、 The principle of Tianlu Environmental Protection Wet Washing Technology:

1. Due to the large amount of water mist and water film formed in the washing device coming into contact with the inhaled gas, pollutant particles collide with the surface of the droplets and adhere to them, increasing the particle volume and effectively separating them from the airflow. At the same time, the acidic gases contained in the exhaust gas also dissolve in the water and combine with the alkaline water mist to form neutral salts, which are separated in full contact with the water phase.

2. The airflow in the system humidifies and enhances the ability of pollutants to aggregate with each other.

3. The turbulent flow of air enhances the diffusion effect of pollution and makes it easy for liquids to adhere.

4. After washing pollutants, the water is recycled. During the recycling process, an appropriate amount of precipitant must be added and the resulting precipitate must be separated. Do not repeatedly add too much precipitate to the cycle to avoid blockage.

2、 Tianlu Environmental ProtectionAcid alkali waste gas treatment equipment in electroplating plantProcess flow description:

The working principle of Tianlu Environmental Protection Waste Gas Treatment Equipment is to separate pollutants from the gas and convert them into harmless substances to achieve the purpose of purifying the gas. It belongs to the differential contact countercurrent type, and the packing inside the tower is the basic component of gas-liquid rain phase contact. It can provide a sufficiently large surface area without causing excessive resistance to gas-liquid flow. Absorbent is the main medium for treating exhaust gas, and its properties and concentration are selected according to the properties of the exhaust gas. The exhaust gas is sucked in by the air duct and passes through the packing layer from bottom to top; The circulating absorbent is sprayed uniformly into the packing layer by the atomized liquid distributor at the top of the tower, and flows downwards along the surface of the packing layer, entering the circulating water tank. Due to the continuous contact between the rising airflow and the descending atomizing absorbent in the packing, the concentration of the fluid in the rising gas becomes lower and lower. The purifier discharges a small amount of harmful substances and dust that have not been adsorbed or absorbed, which are then filtered and adsorbed by activated carbon. After adsorption by activated carbon, the clean gas is discharged to meet the standard.

The lower part of the atomization absorption purifier is equipped with a water storage tank and an automatic water replenishment device. Install a circulating water pump next to the purifier to inject tap water from the storage tank into the top nozzle. After atomization by the nozzle, droplets are formed, increasing the contact area between the exhaust gas and the water mist. Harmful substances and dust in the exhaust gas are more easily absorbed. The harmful substances in the tap water of the water storage tank increase with the use of time and must be cleaned regularly.
