Description

Features of asphalt paint wet scrubber:

The asphalt paint wet scrubber fully contacts the waste gas with the liquid and uses its solubility in water or chemical reaction to reduce its concentration, thereby becoming a clean gas that meets the national emission standards. It is mainly used to treat inorganic waste gas, such as sulfuric acid mist, hydrogen chloride gas, nitrogen oxide gas with different valence states, dust waste gas, etc.

Asphalt paint wet scrubbers are also known as scrubbers, waste gas treatment towers, spray towers, waste gas absorption towers, and waste gas scrubbers. The wet swirl plate exhaust gas purification tower is more advanced in wet dust removal technology. The effect of dust removal, desulfurization, and spray paint removal on boilers is particularly significant. It is also widely used. Compared with other wet processes, the dust removal effect is better. lower. It not only removes more than 95% of paint dust but also ensures low gas humidity and simple water filtration.

Asphalt paint wet scrubber is the simplest equipment for industrial dust removal or waste gas treatment. It has a simple structure, low cost, low gas pressure drop, and no blockage.

The working principle of asphalt paint wet scrubbers can be divided into three forms: co-current, counter-current, and cross-current. Among them, the most commonly used is countercurrent spraying: acid or alkaline acid mist waste gas is introduced into the purification tower through the air duct, passes through the packing layer, and the waste gas is fed from the bottom of the tower. continuous through the voids of the packing layer. On the surface of the filler, the gas-liquid two phases are fully contacted to absorb and neutralize the reaction to adsorb the acidic or alkaline pollutants contained in the exhaust gas. After the acid mist exhaust gas is purified, the clean gas is discharged from the fan into the atmosphere after dehydration and demisting by the defogging plate. Insoluble viscose particles and dust are poured into the collection tank, suspended particles are discharged from the overflow outlet, and the collected sediment is discharged from the sewage outlet. The absorption liquid is pressurized by the water pump at the bottom of the tower and sprayed down at the top of the tower, and finally refluxed to the bottom of the tower for recycling.

Advantages of asphalt paint wet scrubber:

The asphalt paint wet scrubber has low noise, stable operation, simple and convenient operation; the water-washing waste gas treatment system is cheap and the treatment method is simple; the gaseous, liquid and solid pollution sources can be treated; the system has a low-pressure loss, suitable for large air volume; Type filling layer design to deal with mixed pollution sources. It can treat acid and alkaline waste gas economically and effectively, and the removal rate can be as high as 92% or more.

Working principle of asphalt paint wet scrubber:

Dust-laden gas and black smoke tail gas enter the bottom of the asphalt paint wet scrubber through the flue pipe, and the smoke and dust are washed by the spray system. The mist is combined with the circulating spray water to further fully mix in the main body. At this time, the dust particles in the dust-laden gas are captured by the water, and the dust and water are centrifuged or filtered off and flow into the circulating pool through the tower wall due to gravity. The purge gas is discharged. The wastewater is regularly scooped up and transported out of the sludge in the circulating pool.

Asphalt paint wet scrubber applicable industries:

Electronic industry, semiconductor manufacturing, PCB manufacturing, LCD manufacturing, steel metal industry, electroplating and metal surface treatment industry, pickling process, dye/pharmaceutical/chemical industry, deodorization/chlorine neutralization, combustion exhaust gas SOx/NOx Removal and treatment of other water-soluble air pollutants.
