Embodiment Construction

[0044] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0045] In the examples cited in the present invention, there is the sharing of pipelines, so the pipelines connecting various parts cannot be clearly marked, but through the description of the instructions and drawings, those skilled in the art can easily obtain the distribution mode and layout path of each pipeline And shared situation; The direction of the arrow is the determined liquid flow direction under the circumstances given by the embodiment, but it is also limited to the situation given by the embodiment. If the pipeline layout or system structure changes, the direction of the liquid flow should also change accordingly. At the same time, other modifications that do not depart from the essence and spirit of the present invention should also be considered to be included in the present invention.

[0046] In a preferred embodiment, as figure 1 A...

Abstract

The invention relates to the field of liquid treatment, in particular to a filtration system and a filtration method. The filtration system comprises a filter chamber, a process fluid tank and a backwash liquid tank, wherein a sewage discharge pipeline controlled by a control valve is arranged on a first filter pipeline for communicating the process fluid tank with a filter inlet of the filter chamber; the filter chamber is used for filtering process fluid; backwash liquid is used for backwashing the filter chamber and discharging filter residues in the filter chamber from the sewage discharge pipeline; a plurality of pipelines are arranged among the filter chamber, the process fluid tank and the backwash liquid tank; the filtration process and the backwashing process can be performed separately as a plurality of control valves are arranged on the pipelines, so as to achieve the automatic control of the filtration process and the backwashing process while reducing the production costs.

Description

technical field [0001] The invention relates to the field of liquid treatment, in particular to a filtration system and a filtration method. Background technique [0002] Filtration is when the liquid (or gas) in the suspension (or the heating gas containing solid particles) penetrates the medium under the action of driving force or other external force, and the solid particles and other substances are trapped by the filter medium, so that the solid and other substances and the liquid ( or gas) separation operation. When the process fluid passes through the filter material, particles larger than the pores of the filter layer are retained; then, the pores of the filter layer gradually become smaller, and smaller particles are also retained, but this will make the filter impurities highly residual in the filter medium and difficult to clean. This results in a high filter system replacement rate and increased costs. Each pipeline of the filtration system exists independently,...
