Application of High Voltage Power Supply in Sliding Arc Plasma
The treatment of organic wastewater and waste gas is still a thorny problem, which plagues the chemical and pharmaceutical industries. There are many methods for treating wastewater and waste gas in the prior art, and the conventionally recommended biochemical methods, electrolysis methods, and flocculation methods are difficult to solve. The problem of waste water and waste gas treatment is also an urgent problem to be solved in environmental protection.
High-voltage power supply sliding arc discharge plasma is a new technology that has just emerged in recent years and has been applied in environmental protection technology. This method can generate non-equilibrium plasma at atmospheric pressure or higher pressure, and it is useful Technical treatment of H2S, SO2, N2O and other waste gases, there are research reports at home and abroad on the use of sliding arc discharge to treat waste water and waste gas pollution.
The generation method, physical properties and basic principles of the sliding arc discharge of Teslaman high-voltage power supply, as well as the structure of the sliding arc reactor and the application of the reactor in environmental pollution control projects such as waste gas and wastewater treatment, using Dalian Teslaman DC high-voltage power supply A self-made gas-liquid two-phase flow sliding arc discharge plasma degradation mechanism experiment device was used to conduct preliminary treatment tests on pharmaceutical wastewater and concentrated waste liquid of DSD acid. The results showed that CODCr, BOD5, The removal rate of NH3-N can reach more than 99%, which has a good application prospect.
High-voltage power supply sliding arc plasma wastewater treatment Compared with the current wastewater treatment industry that mainly uses biochemical methods, the plasma wastewater processor has higher advantages. (1) It can continuously treat wastewater without long residence time, and remove organic pollutants No selectivity; (2) The raw materials for manufacturing electrodes are cheap, the system occupies a small area, and the operation and maintenance are convenient, and automatic control can be easily realized to ensure the quality of the treatment; (3) No need to add consumables such as medicaments, only Need electricity, convenient and easy to get.
