Problems solved by technology

[0005] However, since the degree of contamination of this filter varies with usage and other conditions, it is impossible to always clean the filter F under the same conditions
For example, in the cleaning condition of a heavily soiled filter, a considerable time loss will occur for the cleaning of a lightly soiled filter
[0006] On the other hand, the short-term cleaning conditions of lightly polluted filters will not be effective enough for heavily polluted filters, and cleaning inside the filter media is sometimes difficult.
[0007] In addition, because the filter F has a frame surrounding the filter media with a complex structure, the contaminants removed from the filter media are reattached to the cleaned filter media, and thus, it is sometimes difficult to completely remove the contaminants

Embodiment Construction

[0033] Such as figure 1 As shown, a support frame 2 of the conveyor units C1 and C2 is provided on a rectangular planar base 1 . Conveyor units C1 and C2 movable in the X and Y directions are installed on the top surface of the support frame 2 . A plurality of guide rails 3 are provided on the base 1 to temporarily accommodate a plurality of filters to be cleaned and cleaned filters. These guide rails 3 are arranged in a plurality of rows in the width direction (X direction) to accommodate a plurality of filters F in the longitudinal direction (Y direction), and each accommodation position is numbered in advance.

[0034] The transportation of the filters to the guide rail 3 is accomplished by a transportation device (not shown) such as a crane or a conveyor belt. The transport unit is equipped with a device for analyzing the degree of contamination of the filter medium (filter insert) to be cleaned. The degree of contamination of the filter medium is determined analytical...

Abstract

In a method and apparatus for cleaning filter, the cleaning is efficiently performed by selecting cleaning steps according to the degree of contamination of the filter media. The degree of contamination of the filter media is analyzed before the filter is carried into the cleaning apparatus. Filter with heavily contaminated filter media is subjected pretreatment before the cleaning process is performed, and the filters with less contaminated filter media is directly subjected to the cleaning process. Then cleaned filter is subjected to restoration process before reuse.

Description

technical field [0001] The present invention relates to a method and apparatus for cleaning filters such as air intake filters and air ventilation filters which are contaminated with dust and other particulates. Background technique [0002] Filters are used in various technical fields in the removal of dust and other particulates from fluids such as air. For example, medium performance filters are used in the air passages of air-conditioning systems in the passages of buildings or underground shopping malls, and in the air intake ducts of power machines such as local gas turbine engines. These filters remove various salts, dust, engine oil particles, fibers and other substances (hereinafter collectively referred to as "pollutants") from the air onto filter media (filter elements) composed of resin fibers or other materials . [0003] Figure 10a and Figure 10b A perspective view showing such a filter. Figure 10a The shown filter F has a filter medium made of a corrugat...
