Embodiment Construction
[0019] The jet aerator provided by the invention is aimed at optimizing the aeration dead angle problem of the jet aerator, and at the same time, the structure of the nozzle is improved, so that the aerator increases turbulent flow and bubbles.
[0020] The jet aerator is designed as a two-stage double-nozzle jet aerator, combining the principles and advantages of two traditional jet aerators, and adopts the mixing method of "two gases and one liquid". "Two gases" refers to compressed air and air blower, and "one liquid" refers to the sewage to be treated by the circulating water pump. After two times of liquid-gas mixing, the oxygen is fully dissolved. Due to the use of compressed air, the use of blowers is reduced, the load of the blowers is reduced, and the aeration load is reduced. The aeration load is 50-70% of the total load of the sewage treatment plant, so reducing the load of the blower is economical. The sex is considerable.

The invention provides an efficient jet aerator. The aerator is provided with a circulating water port; the left side of a compressed air mixing cavity is provided with the circulating water port, andthe circulating water port is connected to a circulating water nozzle in the compressed air mixing cavity; the right side of the compressed air mixing cavity is provided with a low-pressure air mixing cavity, and the low-pressure air mixing cavity is internally provided with a secondary jet orifice; the right side of the low-pressure air mixing cavity is provided with a dissolved oxygen mixing cavity; a partition baffle of the low-pressure air mixing cavity and the dissolved oxygen mixing cavity is provided with an overflow hole; a turbulent flow generation pipe is arranged in the dissolved oxygen mixing cavity; the outer end of the turbulent flow generation pipe is fixedly connected to an air-water release nozzle; the compressed air mixing cavity is externally connected to compressed airthrough a compressed air channel; and the low-pressure air mixing cavity is externally connected to an air blower for aeration through a low-pressure air channel. The efficient jet aerator has the advantages that an air-water mixed solution jetted out by the efficient jet aerator has larger kinetic energy, water in the horizontal direction is stirred more violently, the dead angle is small, gas is cut violently by the structure, and the amount of generated bubbles is large.
Description
technical field [0001] The invention relates to industrial production sewage treatment aeration equipment, in particular to a high-efficiency jet aerator. Background technique [0002] The jet aerator is an aeration device that integrates suction and mixed reaction. It sucks and compresses the gas through the liquid jet to bring air / oxygen into the water to oxygenate the sewage. Because the jet aeration equipment has both oxygenation and push flow functions, its power efficiency is higher than that of the rotary brush aerator, and its maintenance is simpler than that of the microporous aerator. It has been adopted in large foreign sewage plants as early as. However, domestic research on the jet aeration method is relatively late, and a series of jets professionally used for sewage treatment has not yet formed. Although the jet aeration technology for sewage treatment in my country has developed to a certain extent in recent years, there is still a big gap with developed coun...
