Abstract

The invention discloses a detachable underwater jet aeration device with laval spraying pipes. The detachable underwater jet aeration device comprises a jet device, a plurality of jet aeration pipes, a water inlet connecting flange and an air inlet connecting flange; the jet device is detachably arranged on a counterweight base; the jet aeration pipes which are detachably arranged on the jet device are the laval spraying pipes; the water inlet connecting flange is vertically arranged at the top of the jet device; the air inlet connecting flange is arranged on the lateral side of the jet device. The detachable underwater jet aeration device with the laval spraying pipes has the advantages of solving the problem that the traditional jet aeration pipes are difficult to be replaced due to the fact that the traditional jet aeration pipes are fixedly arranged at the pool bottom which is under the water surface, enabling the detachment to be convenient due to the detachably arranged jet device and jet aeration pipes and being capable of enhancing the pressure and increasing the flow velocity due to the laval spraying pipes.

Description

technical field [0001] The invention discloses a detachable underwater jet aeration device, in particular to a detachable underwater jet aeration device using a Lafal nozzle. Background technique [0002] A new process for the biological treatment of wastewater by activated sludge method. In the aeration tank, the jet diffuser is used for oxygenation. Its advantages are strong agitation and mixing ability, high oxygen transfer efficiency, good activated sludge settling performance, suitable for medium-scale aeration tanks, and medium cost. The disadvantage is that the geometric size of the aeration tank is limited, and the nozzles will be blocked. Blast type jet aeration requires a blower and a pump, while suction type jet aeration can save the blower. At present, there are devices in China that use the jet aeration method to treat urban sewage and printing and dyeing wastewater. [0003] The front half of the Rafal nozzle shrinks from large to small to a narrow throat i...
