Efficient energy-saving jet aerator

Abstract

The invention discloses an efficient energy-saving jet aerator which comprises a water flow inlet pipe, a reducing pipe, a hollow throat, an increasing pipe and a gas-liquid mixed outlet pipe, wherein the diameter of the hollow throat is less than that of the water flow inlet pipe and the gas-liquid mixed outlet pipe, the hollow throat is connected with the water flow inlet pipe through the reducing pipe and is connected with the gas-liquid mixed outlet pipe through the increasing pipe, an admission port is arranged on the outer wall of the hollow throat, and a water flow cutter is fixedly arranged at the connection of the reducing pipe and the hollow throat. The aerator disclosed by the invention has the beneficial effects that the water flow cutter is arranged in a pipeline to increase the gas-liquid contact area, and in equal pressure drop, the admission amount is greatly improved, and meanwhile, the shearing effect is further enhanced. The admission port is designed, so that gas paste is easier to be sheared by a high speed shearing water flow so as to obtain a better mass-transfer effect, and therefore, smaller bubbles are cut, and the dissolving efficiency is higher.

Description

technical field [0001] The invention relates to multiple technical fields such as sewage sludge treatment, flue gas treatment, aeration and oxygen enhancement, and in particular to a high-efficiency and energy-saving jet aerator. It can be widely used in various oily and suspended solid sewage treatment, papermaking waste treatment, printing and dyeing wastewater treatment, aeration of sewage treatment plants, aeration grit chamber, desulfurization and dust removal flue gas treatment aeration oxidation, activated sludge treatment, sewage treatment Mud mixed liquid supplementation and mixing, and seafood and agricultural products breeding oxygenation, etc. Background technique [0002] In the field of sewage treatment, the traditional blower aeration, mechanical aeration and jet aeration devices all have large diameter bubbles, small dispersion, low gas (oxygen, etc.) solvent velocity, unsatisfactory dissolution and mixing effects, resulting in air flotation or The aeration ...

AI Technical Summary

Problems solved by technology

[0002] In the field of sewage treatment, the traditional blower aeration, mechanical aeration and jet aeration devices all have large diameter bubbles, small dispersion, low gas (oxygen, etc.) solvent velocity, unsatisfactory dissolution and mixing effects, resulting in air flotation or The aeration efficiency is not high, and the structure is complex, there are many moving parts, and the failure rate is high.
