Description

High-efficient dissolved gas release device Technical Field The utility model belongs to the technical field of sewage treatment, and particularly relates to a high-efficiency dissolved gas release device. Background The dissolved air releaser is a key device in the pressure dissolved air floatation water purification system. The pressure dissolved air floatation water purifying method is a new water treatment technology and has been widely used in China and many advanced industrial countries. The pressure dissolved air water can release a large amount of micro bubbles only after the pressure is reduced and the energy is dissipated through the dissolved air releaser, and the quality of the releaser performance relates to the quantity of released bubbles, the fineness of the bubbles, the distribution law of the size of the bubbles and the like, and directly influences the water purifying effect of an air floatation method and the consumption of electric energy. The existing dissolved gas releaser is not provided with a filtering treatment mechanism for inflow water, so that the doped particulate matters in the sewage are easy to directly enter the dissolved gas releaser to be accumulated to cause blockage, the dissolved gas releaser is required to be disassembled for cleaning, and the working efficiency is reduced. Disclosure of utility model The utility model aims to provide a high-efficiency dissolved gas releasing device, which solves the problems that the prior dissolved gas releaser provided in the background art is not provided with a filtering treatment mechanism for inlet water, so that the doped particulate matters in sewage are easy to directly enter the dissolved gas releaser to be accumulated to cause blockage, and the dissolved gas releaser is required to be disassembled for cleaning, and the working efficiency is reduced.
