Problems solved by technology

The dissolved air flotation technology currently used in the market mainly relies on increasing the dissolved air pressure to increase the amount of dissolved air. The water produced by air flotation needs to be pressurized to the dissolved air pressure. This is most of the energy consumption of the air flotation process, and it also makes the air flotation process usually It is 2-3 times of the energy consumption of the precipitation process, so that the application and popularization of air flotation is limited due to energy consumption

The device comprise a dissolved air tank, an air compressor, a dissolved air water conveying pipeline,an air-liquid conveying pipeline and a bubble releaser, which form a dissolved air loop and a bubble releasing loop. The device and the system have the technical characteristics of energy saving, high-efficiency gas dissolving and convenient gas filling.

Description

technical field [0001] The invention relates to an energy-saving dissolved air type air flotation device and system. Background technique [0002] Such as Figure 4 As shown, in the current dissolved air type air flotation system, in order to enhance the air flotation effect, part of the air flotation produced water is pressurized and dissolved in air and then returns to the inlet. The return flow usually accounts for 10-50% of the air flotation inlet water flow, and the pressure is About 0.5-0.6MPa. The dissolved air flotation technology currently used in the market mainly relies on increasing the dissolved air pressure to increase the amount of dissolved air. The water produced by air flotation needs to be pressurized to the dissolved air pressure. This is most of the energy consumption of the air flotation process, and it also makes the air flotation process usually It is 2-3 times of the energy consumption of the precipitation process, so that the application and popula...
