Abstract: Disclosed is a method for treating sulfur-containing organic wastewater by integrating an energy supply unit and a treatment unit into an integrated device. The treatment unit is used to purify sulfur-containing organic wastewater with an initial concentration of organic sulfur, so that the organic sulfur content in the treated sulfur-containing organic wastewater is within a preset range to enable the device to efficiently purify and treat sulfur-containing organic wastewater with different initial concentrations of organic sulfur, the efficiency of purifying sulfur-containing organic wastewater can be improved to a certain extent, the purification cost can be reduced, and the competitiveness of enterprise can be enhanced.

Abstract: Disclosed are a cross-flow air duct and an air outlet device. The cross-flow air duct includes a volute and a volute tongue. The volute includes a first body, a first side of the first body is an air inlet side, and a second side of the first body is an air outlet side. The volute tongue includes a second body, a first side of the second body is an air inlet side, and a second side of the second body is an air outlet side. An air inlet port is formed between the first sides, and an air outlet port is formed between the second sides. According to the cross-flow air duct, multiple groups of air outlet areas in different directions are formed, the air outlet width is enlarged as a whole, and the air supply range is increased.

Abstract: The present invention discloses a heat exchanger capable of automatically adjusting heat exchange area, which relates to the field of heat exchangers. The key points of the technical solution of the present invention include a heat exchange wall, which includes a fixed heat exchange wall, and a self-adjusting heat exchange wall that can automatically expand and contract according to the flow or temperature of the fluid to change the heat exchange area. The present invention can automatically change the heat exchange area, and timely respond and adapt to different working conditions, having simple structure, low production cost and good stability.
