Problems solved by technology

After the pressure dissolved air water passes through the dissolved air releaser to reduce the pressure and dissipate energy, a large number of bubbles are released, but the dissolved air releaser is easily blocked and needs to be removed for cleaning, which seriously affects the production efficiency

Abstract

The invention provides an improved sewage air floatation device without a releaser. The device comprises a sewage tank and a gas dissolving water pipe, a mixing device is arranged at the front end ofthe gas dissolving water pipe, the mixing device comprises a flaky assembly, a plurality of water outlet holes are formed in the upper surface of the flaky assembly, a plurality of water division pieces are arranged on the flaky assembly, a plurality of water holes are formed in the water division pieces, and the water holes of the water division pieces are not overlapped; a plurality of oblique water outlet holes are formed in the lower surface of the flaky assembly; a plurality of water outlet pipes are arranged at the front end of the flaky assembly; wavy fins are arranged on the inner wallof the water outlet pipes; the water outlet pipes are arranged obliquely and downward; and the gas dissolving water pipe is provided with a spiral stirring device at the lower part of the mixing device to mix the gas dissolving water and the sewage thoroughly. The collecting efficiency of impurities is high and the blockage does not easily occur.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to an improved releaser-free sewage air flotation device. Background technique [0002] Air flotation, as an efficient and fast solid-liquid separation technology, started from ore dressing flotation technology. It is to introduce a large number of dense micro-bubbles into the water to make them adhere to impurities and flocs to form a flotation whose overall specific gravity is smaller than that of water. Floating body, and rely on buoyancy to make it float to the water surface, so as to complete the solid and separated water purification technology. Initially, this technology was mainly used for the removal of fat, oil, fiber, grease and other substances with a density less than water. In the late 1960s, this process was promoted in sewage treatment and drinking water treatment. Now it has been widely used in oil refining, In the treatment of papermaking, printing and dy...
