Efficient gas dissolving pipe

Abstract

The invention discloses a high-efficiency gas-dissolving pipe, which comprises an air-dissolving pipe and an air control cabinet. The air-dissolving pipe is horizontally arranged above the air-control cabinet. Both ends of the air-dissolving pipe are respectively sealed by flanges. Water inlet, the bottom of the other end is provided with a water outlet, the inner bottom of the dissolved gas pipe is provided with a pipe frame, the pipe frame is vertically provided with several uniformly arranged air distribution pipes, and several air outlet holes are uniformly arranged on the air distribution pipe, so An air control device is provided in the air control cabinet, and the air control device is connected to each air distribution pipe through a pipeline. A spray head is provided on the top of the air-dissolving pipe, and a spray pipe is connected to the spray head. One end of the spray pipe is connected to the spray pipe. The tube is connected, and the other end is connected with a nebulizer. The air-dissolving water of the present invention has good effect, simple debugging, convenient operation and maintenance, can replace the traditional pressure-dissolving air tank, improves the processing capacity by more than 30%, greatly improves the efficiency and effect of the dissolved air water, and has a good external Dust removal effect.

Description

technical field [0001] The invention belongs to the technical field of dissolved air flotation equipment for sewage treatment, and in particular relates to a high-efficiency dissolved air pipe. Background technique [0002] The core part of the pressure dissolved air flotation equipment is how to dissolve the air into the water to the maximum extent so as to form highly efficient dissolved air water. At present, all domestic dissolved air flotation equipment uses pressure dissolved air tanks for high-pressure dissolved air. When the high-pressure return water enters the pressure tank from the water inlet, it meets the high-pressure gas generated by the air compressor entering the inlet, and uses the turbulence or obstruction of the packing or grille to make the water and gas mix and contact to the maximum. The pressure difference between water and air dissolves the air in the water. The dissolved air water comes out from the water outlet, and then releases under reduced pr...

Problems solved by technology

There are many disadvantages in this technology, which makes its operation complicated and troublesome. If the air pressure, water pressure, and water volume are not well controlled, it will cause the water to be insoluble or full of air, without water, resulting in air flotation. The effect of the device is unstable, resulting in abnormal operation
