Double-pulse fundamental wave jet aerator

Abstract

The invention discloses a double-pulse fundamental wave jet aerator. The double-pulse fundamental wave jet aerator comprises an air inlet pipe, a throat pipe and a diffusing pipe which are communicated with one another in sequence; a water outlet is formed in the lower end of the diffusing pipe; the upper end of the air inlet pipe is closed, and an air inlet is formed in the side wall of the upper end of the air inlet pipe; a water inlet pipe is arranged at the upper part of the air inlet pipe; the top end of the water inlet pipe is closed; the lower end of the water inlet pipe penetrates through the top end of the air inlet pipe and extends into the air inlet pipe; a jet nozzle is arranged at the lower end of the water inlet pipe; a water inlet is formed in the side wall of the upper end of the water inlet pipe; one side of the water inlet is connected with a bypass pipeline; the bypass pipeline penetrates through the top end of the water inlet pipe, extends into the lower end of the water inlet pipe and is communicated with the jet nozzle; an electromagnetic valve is arranged on the bypass pipeline. In an alternate powering on and off process of the electromagnetic valve under the control of the aerator disclosed by the invention, a fluid forms alternate instable fluids in the water inlet pipe and the bypass pipeline, so that external and internal fluids at two different flowing speeds can be formed; therefore, the inspiratory capacity is increased, and the jet aeration efficiency is improved.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a double-pulse fundamental wave jet aerator. Background technique [0002] There are many ways of aeration and oxygenation in the aerobic section of general sewage treatment, the usual microporous aeration, diving aeration, surface aeration machine, microporous aeration device is easy to aging and easy to damage, cleaning must empty the pool, diving aeration The aerator is also extremely easy to damage, maintenance must use a crane, and the installation cost is high, the aeration method of the aerator will be blocked, the maintenance cost is high, the oxygen supply is not constant, and it is not efficient. [0003] The current aerators have low oxygenation efficiency, high energy consumption, and low dissolved oxygen rate, so that the oxygen for bacteria to live in sewage treatment is insufficient, which affects the effect of sewage treatment, and the cost of aerobic section of se...
