Description

Technical Field

[0001] This application relates to the technical field of cruise ship kitchen equipment, and in particular to a debugging method for a cruise ship kitchen air collecting hood system. Background Art

[0002] The automatic cleaning air collecting hood system of a cruise ship kitchen is a new type of air collecting hood system. It includes a system control cabinet, a water washing hood control cabinet and an air collecting hood. It can completely automatically clean the oil stains and waste in the air collecting hood, and maintain the equipment in an unattended manner, so as to ensure the high efficiency, convenience and reliability of the system. The whole process is controlled by the system control cabinet. The system control cabinet is designed and manufactured according to the USPH (U.S. Public Health Service) guidelines, and is made of 1.5 mm AISI304 stainless steel. The electrical and hydraulic components are respectively arranged in independent compartments. One system control cabinet can manage up to 16 air collecting hoods, and is equipped with a dedicated (Internet of Things) platform, which has advanced all-weather remote monitoring functions, and can realize the automatic management of the ventilation, filter and exhaust chamber cleaning cycles of the air collecting hood. A touch screen is installed on the door of the system control cabinet, providing an intuitive and efficient interface between the control system and the user. The system control cabinet is also equipped with an interface for connecting to the ship automation system, which can realize remote monitoring and management. The system control cabinet is connected to the solenoid valve of the exhaust port damper through a cable, and automatically closes all solenoid valves when receiving a fire alarm signal. In the water washing hood control cabinet, the system control cabinet can realize highly precise control of the drug dosage and washing intensity by controlling the solenoid valves of the hot water supply and the detergent tank. When the water pressure is insufficient, the built-in booster pump can ensure good washing effect, providing guarantee for the periodic washing cycle.

[0003] The high degree of automation of the air collecting hood system greatly facilitates the kitchen operation activities and the management of the ship system. However, at the same time, the complex pipelines also bring more difficulties to the construction and subsequent debugging. The existing debugging process of the air collecting hood system is complex and messy, which not only wastes time and cost, but also easily leads to debugging omissions, and cannot ensure the use safety of the cruise ship kitchen.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0041] The following specific embodiments are provided to help the reader obtain a comprehensive understanding of the methods, devices, and / or systems described herein. However, after understanding the disclosure of this application, various changes, modifications, and equivalents of the methods, devices, and / or systems described herein will be obvious. For example, the order of operations described herein is merely exemplary, and it is not limited to the order set forth herein. Rather, changes that will be obvious after understanding the disclosure of this application can be made, except for operations that must occur in a specific order. In addition, descriptions of features known in the art may be omitted for the sake of clarity and conciseness.

[0042] The features described herein can be implemented in different forms and should not be construed as limited to the examples described herein. Rather, the examples described herein are provided only to illustrate some of the many possible ways of implementing the methods, devices, and / or systems described herein that will be apparent after understanding the disclosure of the present application.

[0043] Throughout the specification, when an element (such as, a layer, region, or substrate) is described as being "on" another element, "connected to" another element, "coupled to" another element, "above" another element, or "covering" another element, it can be directly "on", "connected to", "coupled to", "above", or "covering" the other element, or there can be one or more other elements intervening therebetween. In contrast, when an element is described as being "directly on" another element, "directly connected to" another element, "directly coupled to" another element, "directly above" another element, or "directly covering" another element, there can be no other elements intervening therebetween.

[0044] As used herein, the term "and / or" includes any one of the listed related items and any combination of any two or more of them.

[0045] Although terms such as "first", "second", and "third" may be used herein to describe various components, elements, regions, layers, or parts, these components, elements, regions, layers, or parts are not limited by these terms. Rather, these terms are only used to distinguish one component, element, region, layer, or part from another. Thus, a first component, element, region, layer, or part referred to in the examples described herein may also be referred to as a second component, element, region, layer, or part without departing from the teachings of the examples.

[0046] For ease of description, spatial relationship terms such as "above", "upper", "below", and "lower" may be used herein to describe the relationship of one element to another as shown in the figures. Such spatial relationship terms are intended to include different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, an element described as "above" or "upper" relative to another element will then be "below" or "lower" relative to the other element. Thus, the term "above" includes both the orientation of "above" and "below" depending on the spatial orientation of the device. The device may also be positioned in other ways (e.g., rotated 90 degrees or at other orientations), and the spatial relationship terms used herein will be interpreted accordingly.

[0047] The terms used herein are for describing various examples only and are not intended to limit the present disclosure. Unless the context clearly indicates otherwise, the singular forms are also intended to include the plural forms. The terms "comprising", "including" and "having" enumerate the stated features, quantities, operations, components, elements and / or combinations thereof that exist, but do not preclude the existence or addition of one or more other features, quantities, operations, components, elements and / or combinations thereof.

[0048] Due to manufacturing techniques and / or tolerances, variations in the shapes shown in the drawings may occur. Therefore, the examples described herein are not limited to the specific shapes shown in the drawings, but include changes in shape that occur during manufacturing.

[0049] The features of the examples described herein can be combined in various ways that will be apparent after understanding the disclosure of the present application. In addition, although the examples described herein have various configurations, other configurations are possible as will be apparent after understanding the disclosure of the present application.

[0050] The commissioning method of the cruise ship kitchen exhaust hood system of the present application can be combined with the actual situation of the shipyard to design a regular, concise and fast commissioning method, which can save time and cost more quickly and effectively, and there will be no omission in commissioning, thus ensuring the use safety of the cruise ship kitchen.

[0051] Refer to the following Figure 1 and Figure 2 to describe the structures and functions of the water wash hood control cabinet and the exhaust hood of the present application.

[0052] As Figure 1 shown, the self-cleaning exhaust hood structure and functions of the present application are as follows:

[0053] Air inlet 1, when the work starts, air is supplied from air inlet 1.

[0054] Heat source 2, when the cooking equipment works, oil fumes, water vapor, sundries, etc. rise.

[0055] Blow outlet 3, the lateral wind is blown out from the blow outlet 3 on the left side of the exhaust hood, driving the rising oil fumes, water vapor, sundries, etc. into the right cleaning chamber.

[0056] Centrifugal filter 4 (KSA filter), the centrifugal filter 4 removes grease and sundries through a honeycomb cross-section, causing the air flow to rotate inside the filter, thus generating a "centrifugal" effect.

[0057] Mesh filter 5, the mesh filter 5 disperses and balances the air flow, fills the space, enabling the filter to repeatedly filter more air flow. The mesh filter 5 and the centrifugal filter 4 together form a double-filter effect.

[0058] UV filter 6. The UV filter 6 filters. Most oil and gas molecules are first mechanically filtered by the centrifugal filter 4 and the mesh filter 5. The remaining oil and gas will be filtered by the ultraviolet filtration technology. The ultraviolet system destroys the oil molecules by generating UVC radiation and ozone. The UVC radiation dissolves the protein chains in the oil, and the ozone reacts with the particles in the passing air stream.

[0059] Exhaust port 7. The filtered and cleaned air stream is discharged through the exhaust port 7. The cleaned air stream contains a small amount of ozone, which will continue to clean the subsequent air stream and water stream. Eventually, all the ozone will be converted into oxygen.

[0060] Washing pipe 8. Nozzles are provided on the washing pipe 8. After the gas collection is completed, the gas collection is stopped and the cleaning starts according to the schedule of the water washing hood control cabinet. Hot water with mild detergent is pumped into the gas collection hood spray head to clean the necessary parts, including the drain port 9, the UV lamp and the filter. To ensure the cleaning effect, the gas cut-off valve must be adjusted to the minimum during the cleaning.

[0061] Drain port 9. The waste liquid generated after cleaning is discharged through the drain port 9.

[0062] Ventilation port 10. There is also a ventilation port 10 on the front panel of the gas collection hood, which blows low-speed air to ventilate the working area.

[0063] As Figure 2 shown, the structure and functions of the water washing hood control cabinet of this application are as follows:

[0064] Water inlet pipe 11. Water supply enters the water washing hood control cabinet.

[0065] Booster pump 12. The booster pump 12 is used to increase the water pressure.

[0066] Detergent pump 13. The detergent pump 13 adds detergent to the water.

[0067] Solenoid valve 14. The solenoid valve 14 controls the mixture of detergent and water to enter the gas collection hood.

[0068] Outlet pipe 15. It is used to connect the washing pipe 8 of the gas collection hood.

[0069] PLC 16. A control system based on PLC 16 is used to control various functions.

[0070] Through the technical principle analysis of the kitchen air hood system of the first domestic large cruise ship and combined with the situation of the shipyard, this application focuses on the commissioning and inspection stages here, mainly analyzing the commissioning and inspection of the water-washing hood control cabinet and the air hood. In addition to the complex body structure, the air hood also needs to be connected to a control system, which is integrated in a system control cabinet. The system control cabinet body needs to be installed separately on the bulkhead for operating the air hood and selected technologies such as ultraviolet lamps, water flushing systems, and demand-controlled ventilation, MARVEL technology, etc.

[0071] It should be noted here that the structures and functions of the above system control cabinet, water-washing hood control cabinet, and air hood are all prior arts and are all common general knowledge.

[0072] The commissioning method of this application for the cruise ship kitchen air hood system is as follows:

[0073] The commissioning method includes:

[0074] Preparation steps:

[0075] In order to carry out commissioning quickly and effectively, some tasks should be completed in advance. It is necessary to check whether there is any damage to the appearance of the system control cabinet, water-washing hood control cabinet, and air hood; and check the working states of the system control cabinet, water-washing hood control cabinet, and air hood respectively; and connect the system control cabinet, water-washing hood control cabinet, and air hood for preliminary testing.

[0076] Specifically, in the preparation steps, visually check whether there is any damage to the system control cabinet, water-washing hood control cabinet, and air hood during transportation and storage. If there is damage, install spare parts for the damaged or missing components before commissioning. Ordering spare parts during commissioning will inevitably prolong the commissioning cycle.

[0077] Remove the deflector 91 and check whether the installation positions of the centrifugal filter 4, mesh filter 5, and UV filter 6 of the air hood are correct, and whether they are all at the air outlet 7 of the air hood (near the engine hood).

[0078] Check whether the number of the air hood corresponds to the number of the system control cabinet (one system control cabinet controls multiple air hoods at the same time).

[0079] Connect the system control cabinet, water-washing hood control cabinet, and air hood to build the entire communication network; power on the cruise ship kitchen air hood system and check whether the air dampers (including solenoid valves and damper blades) at the air outlet 7 of the air hood are operating normally and moving unobstructedly. If some communication functions are required between the system and the local system and need to be tested, cables need to be connected and the system needs to be ready for testing.

[0080] The commissioning method includes:

[0081] Inspection and commissioning steps of the air hood cleaning system:

[0082] Inspection steps of the air hood cleaning system: Check the operating status of each component of the air hood and clean each cleaning pipeline of the air hood.

[0083] Specifically (hardware commissioning of the cleaning system), temporarily remove the deflector 91 of the air hood, check and clean the washing pipe 8, the cleaning chamber and the drain pipe ( Figure 1 at the middle drain port 9) of the air hood, and remove all obstacles. Among them, the centrifugal filter 4, the mesh filter 5 and the UV filter 6 of the air hood are accommodated in the cleaning chamber.

[0084] Commissioning steps of the air hood cleaning system:

[0085] In the commissioning steps of the air hood cleaning system, turn on the control cabinets of the air hood and the water washing hood, and commission the air hood cleaning system. Connect the outlet pipe 15 of the water washing hood control cabinet to the washing pipe 8 of the air hood to clean the washing pipe 8, the cleaning chamber and the drain pipe of the air hood. During the cleaning process, check the spray quality and direction of the nozzles of the washing pipe 8.

[0086] Specifically (hardware commissioning of the cleaning system), connect the outlet pipe 15 of the water washing hood control cabinet to the washing pipe 8 of the air hood, and water should be provided from the hot water circuit. For testing, the temperature of the washing water does not need to be very high. During the commissioning process, clean the washing pipe 8, the cleaning chamber and the drain pipe of the air hood, and a temporary drain pipe can be used for testing. Leakage may occur during the washing process. If it is not the pipeline of the air hood, invisible pipes can be checked, such as behind the ceiling or wall panels. During the cleaning process, check the spray quality and direction of the nozzles if necessary.

[0087] The commissioning methods include:

[0088] Inspection and commissioning steps of the air hood exhaust system:

[0089] Inspection steps of the air hood exhaust system: Detect the operating status of each component of the air hood. Specifically (testing program software commissioning), turn on the manual switch of the air damper of the air hood and observe whether the air damper of the air hood opens and whether the display of the system control cabinet is correct; and check the position of the pressure sensor.

[0090] That is, check the mechanical functions of the damper of the air damper at the air outlet 7 of the air hood and its actuator, that is, check whether the (open / closed) displayed on the control panel (screen) of the system control cabinet, the manual switch (open / closed) of the air damper of the air hood, and the air damper of the air hood (open / closed) correspond to each other.

[0091] Commissioning steps for the air hood exhaust system: In the commissioning steps for the air hood exhaust system, turn on the air hood and commission the air hood exhaust system. Check whether the alarm system of the system control cabinet alarms and whether the air damper of the air hood closes immediately when the exhaust pressure of the air hood exhaust system is abnormal.

[0092] Specifically, when commissioning the air hood exhaust system (during the functional commissioning of the UV system), the exhaust should be running and the balancing should be completed. If the exhaust is not running or is abnormal, it means that the pressure detected by the pressure sensor exceeds the maximum pressure value or is lower than the minimum pressure value. At this time, the alarm system of the system control cabinet will alarm and control the air damper of the air hood to close immediately. After commissioning, it is difficult to achieve exhaust balancing at a single exhaust port 7 (on the engine hood) because the balance damper is in the fireproof and closed state, and the UV tube (the UV tube is connected to the pressure sensor) will prevent air flow from entering the damper.

[0093] In addition, when commissioning the air hood exhaust system, the functions of two magnet switches (NTC temperature sensors), the pressure sensor, and the infrared sensor should also be checked. This function is used to cut off the power supply of the UV tube. The infrared sensor is used to detect the temperature of the heat source 2.

[0094] In addition, the network signal and setting commissioning should be checked, the display integrity and settings should be checked, the network signal of the system control cabinet should be checked, and the R / TH sensor should be checked.

[0095] In addition, it is necessary to check whether the fire fuse at the exhaust port 7 of the air hood is intact. When the system control cabinet receives a fire alarm signal, whether the alarm system of the system control cabinet alarms and whether the air damper of the air hood closes immediately.

[0096] In addition, the commissioning method also includes the commissioning steps for the water wash hood control cabinet before the commissioning steps for the air hood cleaning system. The commissioning steps for the water wash hood control cabinet include:

[0097] Check the integrity and functions of the display and operation switches of the water wash hood control cabinet. Check the functions of the manual valve position, the detergent level switch, the booster pump 12, the detergent pump 13, and the solenoid valve 14. The washing pressure will be regulated by the pressure valve. Check the functions of the temperature and pressure gauges and clean the filter.

[0098] The commissioning method includes:

[0099] Commissioning test point records:

[0100] During the commissioning process, necessary data needs to be recorded for subsequent commissioning and inspection requirements.

[0101] The air hood includes the CCW model, and the recorded data is as follows in the table.

[0102]

[0103]

[0104] In summary, the debugging method of the exhaust hood system for the cruise ship kitchen in this application can design a regular, simple and fast debugging method in combination with the actual situation of the shipyard, which can save time and cost more quickly and effectively, and there will be no omission in debugging, thus ensuring the use safety of the cruise ship kitchen.

[0105] Finally, it should be noted that the above-described embodiments are only specific implementation manners of this application, used to illustrate the technical solutions of this application, rather than limiting it. The protection scope of this application is not limited thereto.
