Definitions
- the present invention relates to a nozzle, and more particularly, to a nozzle for cleaning the surface of a filter paper in a water purification plant, in which a washing water is supplied from a surface washing water supply pipe to remove sludge on the surface of the filter paper generated during water purification in a water treatment plant.
- the filter paper of the water treatment plant processes a large amount of water every day, the filtration capacity is degraded by sludge adhering to the surface of the filter paper over time, and thus periodic cleaning is required.
- the surface wash of the upper part of the filter paper is used together with the backwash.
- the washing water is sprayed on the surface of the filter medium to wash the surface of the sludge, and the backwash water then flows back through the filter medium to remove the suspended matter held in the filter medium pores. .
- the surface wash water and the backwash water used for the surface washing and the back washing of the upper part of the filter medium of the water purification plant are introduced into the recovery tank together with the crushed sludge and the suspended substance.
- the washing water is ejected through the nozzle 10 in a state where the nozzle 10 is screwed to the tip of the surface washing water supply pipe 3. To sludge adhering to the surface of the filter medium.
- the washing water supplied from the surface washing water supply pipe 3 collides with the wing member 50 installed in the upper portion of the nozzle hole 43, which is an inner space of the nozzle head member 40, and generates vortex and discharges laterally. Increase the cleaning effect.
- the present invention is to solve the above problems, during the filter paper cleaning process of the water purification plant, during the reverse washing to prevent the filter paper surface sludge splashed up through the inside of the nozzle to the surface washing water supply pipe, while washing water under the same water pressure It is an object of the present invention to provide a nozzle for cleaning a filter paper surface of a water purification plant that increases the discharge efficiency of the sludge and effectively removes the crushed sludge from the surface.
