Device for removing hydrogen sulfide gas in dark culvert river surge based on ultraviolet oxidation and using method thereof

Abstract

The invention discloses a device for removing hydrogen sulfide gas in a dark culvert river surge based on ultraviolet oxidation and a using method thereof. The device comprises a fixed support, a solar cell panel, an ultraviolet lamp, a small hydroelectric generation device, a storage battery and a control system. The hydroelectric generation device and the solar cell panel are respectively connected to the energy storage battery; the energy storage battery and the control system are respectively connected to the ultraviolet lamp; and the ultraviolet lamp is supported by the fixed support. Clean energy such as hydrodynamic force and solar energy is used for supplying power to the ultraviolet lamp, so that the microwave ultraviolet wireless lamp is promoted to irradiate to generate ozone and hydroxyl radicals in water to oxidize hydrogen sulfide and convert the hydrogen sulfide into substances such as sulfate radicals. The device is suitable for decomposing poisonous and harmful gas generated by corruption of pollution impurities in the dark culvert river surge, so that the purpose of eliminating potential safety hazards is achieved, and the technical problem that an existing devicedifficultly removes hydrogen sulfide gas with clean energy, low cost and high efficiency is solved.

Description

technical field [0001] The invention relates to a device for removing toxic gas from a culverted river, in particular to a device for removing hydrogen sulfide gas from a culverted river based on ultraviolet light oxidation and its application method. Background technique [0002] With the acceleration of urban construction and development, the rainwater pipe network system is responsible for collecting and transporting rainwater during the city's heavy rain, which is closely related to whether the urban living environment and the natural environment can live in harmony and balance. [0003] At present, my country's rainwater pipe network system mainly adopts the direct drainage method, and rainwater grates are built on both sides of the road to collect rainwater, and then the rainwater is confluent to the hidden river or rainwater pipeline under the road, and finally discharged into nearby rivers or lakes. [0004] The pollution of urban water environment is mainly due to t...
