Abstract

The invention researches and develops a novel negative-pressure aeration device to solve the problems that an air compressor of an existing deep well aeration device is high in power and energy consumption. The novel negative-pressure aeration device comprises an outer shaft, an inner shaft, an aerator pipe, a negative-pressure aerator pipe and an air flow riser pipe, wherein the inner shaft is arranged inside the outer shaft; the bottom end of the inner shaft is opened, and the bottom end of the outer shaft is closed; the air outlet of the negative-pressure aerator pipe and the air outlet of the aerator pipe are formed in the inner shaft at the same time or formed in the outer shaft at the same time; correspondingly, the air outlet of the air flow riser pipe is formed in the outer shaft or the inner shaft, and is upward. The negative-pressure aerator pipe and the air flow riser pipe are additionally arranged on the novel negative-pressure aeration device on the basis of the existing deep well aeration device, and the automatic aeration running can be realized by virtue of negative pressure generated when water flow in an aeration well reaches a certain flow velocity, so that a great number of energy consumption generated during the operation of the air compressor is reduced, energy sources are saved, the running cost of equipment is reduced at the same time, and the market competitiveness is improved.

Description

technical field [0001] The invention belongs to the technical field of sewage deep well treatment equipment, and in particular relates to a new type of negative pressure aeration device which automatically aerates by utilizing the negative pressure generated by high pressure aeration in a deep well, thereby saving energy consumption of high pressure aeration. Background technique [0002] Sewage deep well treatment technology has been introduced and studied in my country since the 1980s. After decades of development, it has been applied in the fields of urban sewage and industrial wastewater such as food, chemical, printing and dyeing, pharmaceutical and other industries and achieved remarkable results. Deep well aeration is the key technology for deep well treatment of sewage. It is to drill the aeration tank deep into the ground, and enter the compressed air into the aeration well through the high-pressure aeration pipe for aeration. The deep well aeration effect is good an...
