Large-flow recycling filter element and matched cleaning process equipment and operation method

Abstract

The invention discloses a large-flow recycling filter element and matched cleaning process equipment and an operation method. The product comprises an outer support barrel, wherein an inner support barrel is mounted in the outer support barrel, a filter material is contained between the outer support barrel and the inner support barrel, the bottom of the outer support barrel is connected with a lower end cover connected with a support frame, the top of the inner support barrel is connected with a sealing head, the sealing head is connected with an upper end cover, the upper end cover is connected with the outer support barrel, and the outer support barrel, the inner support barrel, the filter material and the sealing head constitute a cleaning filter element. The equipment is used for filter element cleaning.

Description

Technical field: [0001] The invention relates to a large-flow reuse filter element and its matching cleaning process equipment and operation method. Background technique: [0002] The filter cleaning element is the heart of the filter. The cleaning element has a wide range of filtration accuracy and a large degree of selection, which can meet various applications. However, it is necessary to ensure that the cleaning element has a large flow rate, low pressure difference and long service life during use. [0003] The pleated or push-pleated cleaning filter element greatly increases the filter area of ​​the cleaning filter element from the installation structure of the filter material, which can ensure that the cleaning filter element has a large circulation, low pressure difference and high filtration efficiency during the service cycle. Natural gas chemical companies are widely used. The filter medium is a large flow of oil, water or natural gas. After working for a period of time...

AI Technical Summary

Problems solved by technology

After working for a period of time, a large amount of oil sand and other sediments have accumulated on the surface of the filter material, which blocks the pores of the cleaning filter element and greatly reduces the effective flow area of ​​the cleaning filter element. It cannot work normally, which significantly affects the operating efficiency and safety of the equipment. Therefore, it is necessary to clean the cleaning filter element regularly

Due to the special structure of the pleated or push-pleated cleaning filter element, the surface of the filter material is wrinkled, irregular and smooth, and the trapped blockage is relatively viscous, so it is difficult to clean thoroughly with the existing cleaning methods

[0004] In the prior art, the large-flow cleaning filter element generally adopts the push pleat type, which has the defects of low filtration accuracy and incomplete cleaning; at the same time, in the existing cleaning technology, most of the cleaning methods are manually brushed or rinsed with nozzles, but the manual cleaning effect It is not ideal, the cleaning is not clean, and the water is easy to scatter around, the sewage is not easy to be treated centrally, and it is easy to cause secondary pollution, which cannot meet the cleaning quality requirements of the pleated or push pleated cleaning filter element
