Description

Technical Field

[0001] The utility model relates to the technical field of ship cleaning, in particular to a ship flue cleaning system. Background Art

[0002] The discharge of oil fume in the ship galley depends on the flue system. Long-term use will inevitably lead to a large amount of oil dirt and grease accumulating in the flue. These oil dirt and grease will not only reduce the smoke exhaust efficiency of the flue, but also easily deteriorate and corrupt when accumulated inside for a long time, thus generating peculiar smells. They will also increase the fire risk. Once the grease encounters an open flame at high temperature, a violent fire will occur, causing property losses and safety hazards to the ship.

A drain pipe is connected to the lower side wall of the ventilation air duct near the gas collecting hood end. The drain pipe is communicated with an oil-water separator.

[0006] Further, the cleaning system further includes a compressed air tank. The compressed air tank is communicated with the chemical liquid mixing pipe through a compressed air pipe.

[0007] Further, the ventilation air duct includes a horizontal air duct and a vertical air duct. One end of the horizontal air duct is communicated with the gas collecting hood. The chemical liquid mixing pipe is communicated with the vertical air duct.

[0008] Further, the chemical liquid mixing pipe includes a main pipe, two secondary main pipes and a plurality of branch pipes. The two secondary main pipes are communicated with the main pipe. The plurality of branch pipes are divided into two groups and are respectively communicated with one of the secondary main pipes. The two groups of branch pipes are arranged on opposite sides of the vertical air duct. Each group of branch pipes is arranged at intervals along the height direction of the vertical air duct.

[0009] Further, a plurality of branch pipes in the two groups of branch pipes are arranged in a vertically staggered manner on opposite sides of the vertical air duct.

[0010] Further, the branch pipes penetrate through the vertical air duct, and a spray head is connected to the outlet pipe of the branch pipes.

[0011] Further, stop check valves are provided on the compressed air pipe, the hot water pipe and the drain pipe.

[0012] The ship flue cleaning system of the utility model uses the hot water in the hot water tank, sends the mixed water into the flue through the mixed medicine tank, sprays it into the interior of the flue through the nozzle to dissolve the oil dirt in the flue, and then discharges the cleaned sewage into the oil-water separator through the flue discharge pipe. Then, compressed air is used to clean the residual water in the pipeline and the flue. The stop check valves of the hot water pipe and the compressed air pipe can prevent the reverse passage of the medium in the pipeline. The stop valve of the discharge pipeline is opened during cleaning and closed at other times. Description of the Drawings
