Multi-layer efficient dissolved air releaser

Abstract

The invention discloses a multi-layer efficient dissolved air releaser. The dissolved air releaser comprises a shell, a pipeline pump and an air compressor, wherein a water outlet is formed in the left end of the shell; a water inlet is formed in the right end of the shell; the lower end of the water outlet is connected with an air-dissolved water pipeline; a pipeline pump, a pipeline filter, a first regulating valve, a first flow meter and a pressure gauge are arranged on the outer side of the air-dissolved water pipeline, and are arranged in order from right to left; the upper end of the air-dissolved water pipeline is connected with an air pipeline; the lower end of the air pipeline is connected with an air feeding pipeline, and the outer side of the air feeding pipeline is provided with a second flow meter and a second regulating valve which are sequentially arranged from top to bottom. According to the multi-layer efficient dissolved air releaser, a releasing area can be formed atthe joint of the water inlet, the air-dissolved water pipeline and the air pipeline through the shape structure of the water inlet, the air-dissolved water pipeline and the air pipeline, dissolved air water with released air enters the shell through the water inlet and is finally discharged from the water outlet, and therefore, the air dissolving efficiency is higher.

Description

technical field [0001] The invention relates to the technical field of dissolved air releasers, in particular to a multi-layer high-efficiency dissolved air releaser. Background technique [0002] The dissolved air releaser is the key device in the pressure dissolved air flotation water purification system. The pressure dissolved air flotation water purification method is to introduce a large number of fine air bubbles released from the pressure dissolved air water into the water to be treated, and use them to adhere to solid impurities. The buoyancy of the air bubbles achieves the rapid separation of solid and liquid, and improves the concentration of scum. The pressure dissolved air water can release a large number of fine air bubbles only after the device is depressurized and energy-dissipated. The performance of the releaser is good. Bad, it involves the amount of bubbles released, the fineness of the bubbles and the distribution rate of the bubble size, etc., which dire...

Problems solved by technology

[0004] The purpose of the present invention is to provide a multi-layer high-efficiency dissolved air releaser to solve the above-mentioned background technology. For different sewage, the required amount of air bubble release is also different, and for some sewage pools that require a large number of air bubbles, the dissolved air The speed of gas release in the water has a great influence on the treatment work. If the release speed is too slow, it may lead to insufficient buoyancy for the impurities in the sewage to float, and the long-term use of impurities will block the diffusion tube.
