<p>A cleaning system for a ventilating duct, especially an automatic cleaning system for a ventilating duct, mainly comprises the ventilating duct (1), a water pipe system and a control system. The ventilating duct (1) is mounted in a horizontally inclined manner; a sewage conduit (2) is arranged at the undermost part of the horizontally inclined ventilating duct; the water pipe system comprises water channel pipes (3), connecting pipes (4) and flexible rubber hoses (5); tee pipe couplings (6) are arranged between the water channel pipes; one ends of the tee pipe couplings are connected with the connecting pipes (4); the connecting pipes (4) are communicated with the flexible rubber hoses (5) through water pipe connectors (7); the flexible rubber hoses (5) are placed in the ventilating duct through corresponding through holes of the ventilating duct (1). After water enters under the pressure of a booster pump, water pressure prompts the flexible rubber hoses (5) to spray water at random to achieve the duct cleaning effect; and after cleaning, sewage flows into the sewage conduit in the inclining direction of the ventilating duct to achieve the blowdown effect. Therefore, the whole automatic cleaning system for the ventilating duct is simple to operate, and greatly reduces the cleaning cost without other appliances and manual treatment.</p> |
