Waste gas from acid washing of gold and jewelry

Composition of waste gas from jewelry and gold jewelry processing: Waste gas from jewelry and gold jewelry processing is mainly generated during the acid washing process of the product after removing dirt from the polishing process. Acid washing: uses acid solution to treat the surface of the jewelry, making it whiter (white) and brighter. During this process, acid containing waste gas and acid washing waste liquid will be generated. Main components: The main pollutant is sulfuric acid mist.

Waste gas treatment process for jewelry and gold jewelry processing:

Jewelry and gold jewelry processing waste gas treatment equipment:

The acid mist treatment spray tower equipment is currently mostly used for the treatment of corrosive gases (such as acid and alkaline waste gases) through liquid absorption method. The key to using liquid absorption method to treat this waste gas lies in the selection of waste gas treatment equipment. This waste gas treatment process and product have the characteristics of simple structure, low energy consumption, high purification efficiency, and wide applicability. The acid mist waste gas is introduced into the acid mist purification tower through an air duct, passes through a packing layer, and undergoes gas-liquid two-phase contact absorption and neutralization reaction with sodium hydroxide solution. After purification, the acid mist waste gas is dehydrated and defogged by a defogging plate, and then discharged into the atmosphere by a fan. The absorption liquid is pressurized by a water pump at the bottom of the tower, sprayed down from the top of the tower, and finally refluxed to the bottom for recycling.

The acid mist treatment spray tower equipment adopts a packed tower for exhaust gas treatment, which is suitable for continuous and intermittent exhaust gas treatment; The organic waste gas treatment method is simple, and the management, operation, and maintenance are quite convenient and concise, without causing any impact on the production of the workshop; Widely applicable and capable of purifying multiple types of pollutants simultaneously; Low pressure drop, high operational flexibility, and excellent defogging performance; The tower body can be made of materials such as FRP/PP/PVC according to the actual situation; The packing adopts efficient and low resistance Ball rings, which can thoroughly remove odors, harmful substances, etc. from the gas.
