Backwashing-free filtering device utilizing bubble technology and process of backwashing-free filtering device

Abstract

The invention relates to the technical field of filtering devices, and discloses a backwashing-free filtering device utilizing a bubble technology, the backwashing-free filtering device comprises a cylinder, the right side of the top of the cylinder is communicated with a water inlet pipe, the top of the cylinder is fixedly provided with a skimming mechanism located on the left side of the water inlet pipe, and the left side of the cylinder is fixedly provided with a bubble generator; the bottom of the bubble generator is communicated with a connecting pipe, an air pump is fixedly installed on the left side of the barrel, the air inlet end of the air pump is communicated with the connecting pipe, the air outlet end of the air pump is communicated with a flow guide pipe with one end penetrating through and extending into the cylinder, and the top of the flow guide pipe is communicated with a plurality of air outlet pipes located in the cylinder. According to the backwashing-free filtering device utilizing the bubble technology and the process of the backwashing-free filtering device, a gravel layer is replaced by the bubble layer of the whole device, so that backwashing operation is omitted, energy consumption is correspondingly reduced, and the device is light and easy to install and carry due to the fact that the device is simple in structure and free of the gravel layer.

Description

technical field [0001] The invention relates to the technical field of filtering devices, in particular to a backwash-free filtering device using air bubble technology and a process thereof. Background technique [0002] Sewage treatment is the process of purifying sewage to meet the water quality requirements of being discharged into a certain water body or reused. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment and catering. field, and more and more into the daily life of ordinary people. [0003] At present, most of the sewage is discharged directly after concentration. There are a lot of impurities and some nutrient-rich substances in the sewage. Discharging into nature will cause great pollution to the environment and destroy the natural ecological balance. The existing municipal sewage The treatment of sewage needs to be filtered fir...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a backwash-free filter device and process using air bubble technology, which has the advantage of no backwash, and solves the need to filter the sewage first in the treatment of existing municipal sewage , but after a period of time, impurities are easy to adhere to the surface of the filter element for filtration, which affects the filtering effect of the filter element. At this time, the filter element needs to be replaced and cleaned manually, which affects the filtration efficiency of sewage
