Embodiment Construction

[0009] The present invention will be described in further detail below in conjunction with the embodiments shown in the accompanying drawings.

[0010] as attached figure 1 A pressure-type mechanical filtration system is formed, and the main equipment includes a high-level raw water tank (1), a check valve (2), a mechanical filter (3), a solenoid valve (4), a low-level clean water tank (5), and a backwash pump (6) and check valve (7) constitute. (8) is backwashing sewage pipe.

[0011] During forward filtration, the raw water enters the mechanical filter (3) from the high-level raw water tank (1) through the check valve (2) for filtration, and the filtered clean water flows into the low-level clean water tank ( 5). Due to the effect of the check valve (7), clear water will not pass through the backwash water pump (6).

[0012] When the filter system is cleaning the filter, the electric control system controls the solenoid valve (4) and the backwash water pump (7) to perfor...

Abstract

The invention discloses a pulsating cleaning method used for filtering equipment, which mainly relates to the cleaning of water treatment filtering equipment. The invention belongs to the technical field of water treatment, and can also be used for the cleaning process of the fluid filtering equipment for gas, oil materials and the like. The invention has the technical scheme that the pulsating cleaning method disclosed by the invention is characterized in that a back flushing mode and a positive flushing mode are alternately adopted in the cleaning cycle of the filtering equipment, and in addition, the invention has the advantages of simplicity and easy implementation. The invention uses the cleaning process of water treatment mechanical filters, can effectively improve the cleaning effect, shorten the time, and save water.

Description

Technical field [0001] The invention discloses a pulsation cleaning method for filters, mainly relates to the cleaning of water treatment filter equipment, belongs to the technical field of water treatment, and can also be used in the cleaning process of fluid filter equipment such as gas and oil. Background technique [0002] The filter equipment can effectively intercept the suspended impurities in the fluid in the filter material layer. When the impurities intercepted by the filter material reach a certain amount, it is necessary to use the flushing method to remove the impurities blocked in the filter material layer, so that the filter material can be cleaned again. . The cleaning methods of the currently used water treatment mechanical filters mainly include: mechanical agitation hydraulic backwash, large flow hydraulic backwash, compressed air plus dissolved air water backwash, compressed air or steam backwash. Mechanical agitation hydraulic backwashing must consume a...
