Description

Technical Field

[0001] The invention belongs to the technical field of ship auxiliary equipment, and in particular relates to a kitchen sewage treatment system of a car roll-on / roll-off ship and the car roll-on / roll-off ship. Background Art

[0002] At present, due to cooking, the kitchen sewage of car ro-ro ships contains a lot of grease, which condenses inside the pipes, which will inevitably cause the diameter of the ship's pipes to gradually become smaller and eventually become blocked. Due to the special structure of car ro-ro ships, it is difficult to set the slope of the drainage pipes that rely on gravity discharge. The pipes have no slope, resulting in poor sewage flow.

[0003] Because the garage of the car roll-on / roll-off ship needs to be constantly ventilated with the outside world, the temperature inside the garage is relatively low, which causes the pipes to freeze.

[0004] Therefore, how to provide a kitchen sewage treatment system for a car roll-on / roll-off ship and a car roll-on / roll-off ship that can separate grease, ensure smooth kitchen drainage pipes, and protect the environment has become a technical problem that needs to be solved urgently. Summary of the invention

[0005] The embodiment of the present invention provides a kitchen sewage treatment system of a car roll-on / roll-off ship and a car roll-on / roll-off ship, which can separate grease, ensure the smooth flow of kitchen drainage pipes, and protect the environment.

[0006] In one embodiment of the present invention, a kitchen sewage treatment system for a car roll-on / roll-off ship is provided, the system comprising: a backwash discharge unit, a compressed air flushing unit, a steam pipeline flushing unit and an oil skimmer treatment unit arranged in the engine room of the car roll-on / roll-off ship.

[0007] The backwash discharge unit is connected to the drainage pipeline of the galley of the car ro-ro ship, and includes: a backwash discharge cabinet, a flow switch, a liquid level alarm sensor and a centrifugal pump; the centrifugal pump is used to pump the sewage in the backwash discharge cabinet into the drainage pipeline of the galley of the car ro-ro ship to flush the drainage pipeline when the drainage pipeline is blocked and the sewage inside the backwash discharge cabinet triggers a high liquid level alarm;

[0008] The compressed air flushing unit and the steam pipeline flushing unit are connected in parallel to the drainage pipeline of the car ro-ro ship kitchen, and the compressed air flushing unit and the steam pipeline flushing unit alternately flush the drainage pipeline, so that the grease inside the drainage pipeline is discharged into the car ro-ro ship reverse flushing discharge cabinet connected to the end of the drainage pipeline;

[0009] The skimmer processing unit is used for preliminary treatment of sewage entering the engine room of the car roll-on / roll-off ship, removing grease through the upper structure of the skimmer, discharging sludge through the lower sewage outlet, and discharging water through the middle structure of the skimmer.

[0010] Furthermore, the flow switch and the liquid level alarm sensor are respectively connected to the kitchen control system of the car ro-ro ship, and are used to transmit the alarm signal to the kitchen control system to notify the kitchen control system handler of the car ro-ro ship to eliminate the alarm fault.

[0011] Furthermore, a first stop valve, a second stop valve, a compressed air valve and a steam valve are arranged at the inlet of the drainage pipeline of the car roll-on / roll-off ship, the first stop valve is closed, the second stop valve is opened, and the drainage pipeline is alternately flushed through the compressed air valve and the steam valve, so that the grease in the drainage pipeline is discharged into the car roll-on / roll-off ship reverse flushing discharge cabinet connected to the end of the drainage pipeline.

[0012] Furthermore, the black water system of the car roll-on / roll-off ship is connected to the drainage pipeline of the car roll-on / roll-off ship kitchen, and a stop valve is arranged between the black water system and the drainage pipeline to separate them. When the drainage pipeline of the car roll-on / roll-off ship kitchen is blocked, the black water system uses the suction force of the vacuum system to clean the blockage in the drainage pipeline.

[0013] Furthermore, the drainage pipeline is installed adjacent to the air-conditioning heating pipeline in the steam system and is covered with heat-insulating material together.

[0014] Furthermore, the car roll-on / roll-off ship backwash discharge cabinet is provided with a set of ultraviolet disinfection devices for disinfecting sewage.

[0015] In yet another embodiment of the present invention, a car roll-on / roll-off ship is provided, wherein the roll-on / roll-off ship comprises a carbon dioxide fire extinguishing system for a car roll-on / roll-off ship as described in any one of the above items.

[0016] The beneficial effects brought by the present invention are as follows:

[0018] Figure 1 A schematic structural diagram of a kitchen sewage treatment system for a car roll-on / roll-off ship according to an embodiment of the present invention is shown. DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution in the embodiment of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiment of the present invention. Obviously, the described embodiment is a part of the embodiment of the present invention, not all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] like Figure 1 As shown, Figure 1 The present invention is a schematic structural diagram of a kitchen sewage treatment system for a car roll-on / roll-off ship according to an embodiment of the present invention.

[0021] Figure 1 A kitchen sewage treatment system for a car ro-ro ship includes: a backwashing discharge unit, a compressed air flushing unit, a steam pipeline flushing unit and an oil skimmer treatment unit arranged in the engine room of the car ro-ro ship.

[0022] The backwash discharge unit is connected to the drainage pipeline of the galley of the car ro-ro ship, and includes: a backwash discharge cabinet, a flow switch, a liquid level alarm sensor and a centrifugal pump; the centrifugal pump is used to pump the sewage in the backwash discharge cabinet into the drainage pipeline of the galley of the car ro-ro ship to flush the drainage pipeline when the drainage pipeline is blocked and the sewage inside the backwash discharge cabinet triggers a high liquid level alarm;

[0023] The compressed air flushing unit and the steam pipeline flushing unit are connected in parallel to the drainage pipeline of the car ro-ro ship kitchen, and the compressed air flushing unit and the steam pipeline flushing unit alternately flush the drainage pipeline, so that the grease inside the drainage pipeline is discharged into the car ro-ro ship reverse flushing discharge cabinet connected to the end of the drainage pipeline;

[0024] The skimmer processing unit is used for preliminary treatment of sewage entering the engine room of the car roll-on / roll-off ship, removing grease through the upper structure of the skimmer, discharging sludge through the lower sewage outlet, and discharging water through the middle structure of the skimmer.

[0025] In the embodiment of the present invention, the horizontal distance between the kitchen of the car ro-ro ship and the cabin skimmer is more than 70m, the span is extremely large, and the drainage is extremely difficult. Since the density of the grease in the sewage station is small, it floats on the skimmer. The grease can be removed through the hole structure on the skimmer, and can also be discharged through the valve hole structure in the middle of the skimmer. The density of water is medium and can be directly discharged from the skimmer. The density of the sludge is large, and the sludge is discharged from the bottom of the skimmer through the sewage outlet below the skimmer.

[0026] It is understandable that in other implementations of the present invention, depending on the different structures of the oil skimmer, other methods can also be used to separate grease, sewage and sludge, and the specific structural form is not specifically limited here.

[0027] In another embodiment of the present invention, the flow switch and the liquid level alarm sensor are respectively connected to the kitchen control system of the car roll-on / roll-off ship, and are used to transmit the alarm signal to the kitchen control system to notify the kitchen control system handler of the car roll-on / roll-off ship to eliminate the alarm fault.

[0028] In another embodiment of the present invention, a first stop valve, a second stop valve, a compressed air valve and a steam valve are provided at the inlet of the drainage pipeline of the car roll-on / roll-off ship, the first stop valve is closed, the second stop valve is opened, and the drainage pipeline is alternately flushed through the compressed air valve and the steam valve, so that the grease in the drainage pipeline is discharged into the car roll-on / roll-off ship reverse flushing discharge cabinet connected to the end of the drainage pipeline.

[0029] In another embodiment of the present invention, the black water system of the car roll-on / roll-off ship is connected to the drainage pipeline of the kitchen of the car roll-on / roll-off ship, and a stop valve is provided between the black water system and the drainage pipeline to separate them. When the drainage pipeline of the kitchen of the car roll-on / roll-off ship is blocked, the black water system uses the suction force of the vacuum system to clean the blockage in the drainage pipeline.

[0030] In the embodiment of the present invention, the black water system of the car ro-ro ship is a vacuum sewage system, and a pipeline of the vacuum sewage system of the ship is connected to the kitchen sewage drainage pipeline, and the systems are separated by a stop valve. When the kitchen sewage drainage pipeline is found to be blocked, the suction force of the vacuum system is used to clear the blockage in the pipeline.

[0031] In yet another embodiment of the present invention, the drainage pipeline is installed adjacent to the air-conditioning heating pipeline in the steam system and is coated with heat-insulating material together.

[0032] In the embodiment of the present invention, the air conditioning heating pipeline in the steam system and the skimmer drainage pipeline are installed adjacent to each other. The two pipelines are covered with heat insulation together, and the heat of the steam pipeline is used to keep the skimmer drainage pipeline at a higher temperature, so that the grease inside the pipeline remains in a liquid state and is not easy to solidify.

[0033] In yet another embodiment of the present invention, the car roll-on / roll-off ship backwash discharge cabinet is provided with a set of ultraviolet disinfection devices for disinfecting sewage.

[0034] The ultraviolet disinfection device may be an ultraviolet disinfection lamp or other ultraviolet disinfection devices for disinfecting sewage, and is not specifically limited here.

[0035] In the embodiment of the present invention, when the drainage pipeline of the kitchen of the car roll-on / roll-off ship is blocked or the flow is not smooth, the sewage will flow to the backwashing cabinet along the pipeline where the stop valve is located. When the water flows through the flow switch, the flow switch transmits an alarm signal to the kitchen, and the kitchen staff is informed that the sewage main line is blocked or close to being blocked. When the amount of sewage inside the backwashing discharge cabinet increases, a high liquid level alarm will be triggered. After receiving the signal, the kitchen staff will start the centrifugal pump to pump the sewage in the backwashing discharge cabinet into the sewage main line. The operation is completed and the system is restored.

[0036] Among them, the backwash discharge cabinet and the centrifugal pump can also serve as cleaning devices. Fill the backwash discharge cabinet with water and add an appropriate amount of detergent. Turn on the centrifugal pump to pump the cleaning solution in the backwash discharge cabinet into the sewage main line to flush the pipeline. After the operation is completed, restore the system.

[0037] In yet another embodiment of the present invention, there is provided a car roll-on / roll-off ship, the roll-on / roll-off ship comprising any one of the above items.

[0038] In the embodiment of the present invention, a carbon dioxide fire extinguishing system for a car ro-ro ship can ensure that the kitchen sewage pipeline is unblocked, creating a clean and hygienic working and living environment for the crew. In particular, the grease inside the skimmer is processed to protect the environment.

[0039] The above are preferred embodiments of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
