Description

Technical Field

[0001] The present invention relates to the technical field of ship design, and in particular to a ship boiler water feeding device. Background Art

[0002] In traditional container ships, the equipment layout of the boiler feed water system is relatively scattered, and this design has many problems. The two abandoned boiler feed water pumps and the two auxiliary boiler feed water pumps are not only far apart, but also have a large number of pipe connections, which not only increases the cost of laying pipes, but also wastes a lot of pipes. In addition, this decentralized layout also leads to poor coordination between equipment, increasing the complexity and maintenance difficulty of the system. In ships with smaller engine room areas such as liquefied gas ships, the problem of the inability to centrally arrange equipment is more prominent. Due to the limited space in the engine room, the decentralized layout of equipment further increases the space occupancy. This not only limits the installation and layout of other equipment, but may also cause mutual interference between equipment, affecting the overall performance and safety of the ship.

[0003] This decentralization of traditional design also brings a series of other problems. Due to the wide distribution of equipment, multiple hoisting operations are required during the installation process, which not only increases the difficulty and risk of construction, but also may lead to delays in the construction period. In addition, the decentralized equipment layout also increases material waste because more pipes and connectors are required to connect equipment. These factors combined not only increase the construction cost of the ship, but also reduce the operating efficiency of the ship. In short, the traditional boiler feed water system equipment layout cannot achieve integrity and completeness. Its decentralized equipment layout not only increases space occupancy and material waste, but also leads to an extension of the construction period and an increase in maintenance costs. Summary of the invention

DETAILED DESCRIPTION

[0031] The following describes the embodiments of the present invention through specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention.

[0032] It should be noted that the illustrations provided in this embodiment only illustrate the basic concept of the present invention in a schematic manner. Although the illustrations only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation, the form, quantity, positional relationship and proportion of each component in actual implementation can be changed at will under the premise of realizing the technical solution of this party, and the component layout form may also be more complicated.

[0033] This embodiment provides a ship boiler water supply device, referring to Figures 1 to 5 The ship boiler water supply device includes a main boiler group 003 and an auxiliary boiler group 004, which are arranged on the iron stern base 01 at intervals. The main boiler group 003 includes a main boiler 03, a main water pipe 1 and a main boiler feed water pump 3, the main water pipe 1 is connected with the main boiler 03 and the hot well 02 of the ship, and the main boiler feed water pump 3 is arranged on the main water pipe 1; the auxiliary boiler group 004 includes an auxiliary boiler 04, an auxiliary water pipe 2 and an auxiliary boiler feed water pump 4, the auxiliary water pipe 2 is connected with the auxiliary boiler 04 and the hot well 02, and the auxiliary boiler feed water pump 4 is arranged on the auxiliary water pipe 2. In order to make the ship boiler water supply device structure balanced and easy to maintain, in an optional embodiment of the present embodiment, the main boiler feed water pump 3 and the auxiliary boiler feed water pump 4 are symmetrically arranged on the iron stern base 01.

[0034] In an alternative embodiment of this embodiment, refer to Figure 5, the length of the stern base 01 is between 2000mm and 2500mm, the height of the stern base 01 is between 1000mm and 1500mm, and the width of the stern base 01 is between 1000mm and 1500mm. Preferably, the length of the stern base 01 is 2166mm, the height of the stern base 01 is 1453mm, and the width of the stern base 01 is 1271mm. The auxiliary boiler feed pump 4 and the main boiler feed pump 3 are the core of the ship boiler feed water device. The auxiliary boiler feed pump 4 and the main boiler feed pump 3 are mainly used to provide a stable water supply for the main boiler 03 and the auxiliary boiler 04. When the auxiliary boiler feed pump 4 and the main boiler feed pump 3 heat fresh water by burning fuel or using waste heat from exhaust gas, steam is generated, which is then transported to various user ends on the ship to meet different process requirements. In the process of steam being transported to the user and completing heat exchange, its own latent heat of vaporization will be transferred to the user, thereby achieving effective heat transfer. In this process, the steam will gradually cool and turn into condensed water. These condensed water will not be wasted, but will be collected and returned to the hot well 02 through the condensation system. However, during the operation of the main boiler 03 and the auxiliary boiler 04, the total amount of boiler water will gradually decrease due to the continuous evaporation of boiler water. In order to ensure that the main boiler 03 and the auxiliary boiler 04 can operate continuously and stably and avoid safety problems caused by water shortage, the main boiler 03 and the auxiliary boiler 04 must be replenished with water in time. The auxiliary boiler feed water pump 4 and the main boiler feed water pump 3 play a key role in this link. The auxiliary boiler feed water pump 4 and the main boiler feed water pump 3 transport the steam condensed water collected in the hot well 02 back to the main boiler 03 and the auxiliary boiler 04 through pipelines, thereby replenishing the water lost by the boiler due to evaporation. This process not only ensures the stability of the water level in the main boiler 03 and the auxiliary boiler 04, but also ensures that the main boiler 03 and the auxiliary boiler 04 can continue to generate steam and maintain the normal operation of the ship's boiler water supply device. The stable operation of the auxiliary boiler feed pump 4 and the main boiler feed pump 3 is the basic guarantee for the efficient and safe operation of the entire ship's boiler water supply device.

[0035] Reference Figures 1 to 4The feedwater pump control button group 5 includes a main boiler feedwater pump control button 51 and an auxiliary boiler feedwater pump control button 52. The main boiler feedwater pump control button 51 is connected to the main boiler feedwater pump 3, and the auxiliary boiler feedwater pump control button 52 is connected to the auxiliary boiler feedwater pump 4. When the ship boiler feedwater device needs to extract condensate or replenish feedwater from the main boiler 03 or the auxiliary boiler 04, the operator can start the main boiler feedwater pump 3 or the auxiliary boiler feedwater pump 4 through the main boiler feedwater pump control button 51 or the auxiliary boiler feedwater pump control button 52 to transport water to the main boiler 03 or the auxiliary boiler 04. When it is not necessary to supply water to the main boiler 03 and the auxiliary boiler 04 or the main boiler feed pump 3 or the auxiliary boiler feed pump 4 needs maintenance, the operator can stop the main boiler feed pump 3 or the auxiliary boiler feed pump 4 through the main boiler feed pump control button 51 or the auxiliary boiler feed pump control button 52, which can prevent the main boiler feed pump 3 and the auxiliary boiler feed pump 4 from continuing to operate when not needed, thereby saving energy and avoiding unnecessary wear. In the event of remote control failure, such as a failure of the central control system of the ship or an interruption of the communication line, the main boiler feed pump control button 51 and the auxiliary boiler feed pump control button 52 can be used as a backup means to ensure that the operator can still directly control the operating status of the main boiler feed pump 3 and the auxiliary boiler feed pump 4. During the installation and commissioning stage of the ship boiler feed water device or when maintaining the ship boiler feed water device, the main boiler feed pump control button 51 and the auxiliary boiler feed pump control button 52 can easily operate the main boiler feed water pump 3 and the auxiliary boiler feed water pump 4 separately. For example, when checking whether the mechanical performance, motor operation status or pipeline connection of the main boiler feed pump 3 and the auxiliary boiler feed pump 4 are normal, the operator can operate the main boiler feed pump control button 51 and the auxiliary boiler feed pump control button 52 to start or stop the main boiler feed pump 3 and the auxiliary boiler feed pump 4 for a short time, so as to carefully observe and adjust the main boiler feed pump 3 and the auxiliary boiler feed pump 4 to ensure the normal operation of the main boiler feed pump 3 and the auxiliary boiler feed pump 4. In order to increase the reliability of the ship boiler feed water device, the ship boiler feed water device includes 2 main water pipes 1, 2 auxiliary water pipes 2, 2 main boiler feed water pumps 3 and 2 auxiliary boiler feed water pumps 4.

[0036] Reference Figures 1 to 4The ship boiler water supply device also includes an operation and maintenance platform 11 and a dosing device 12. The operation and maintenance platform 11 is located on the iron wing base 01 and is arranged between the main boiler water supply pump 3 and the auxiliary boiler water supply pump 4 to repair the ship boiler water supply device. The dosing device 12 is located on the iron wing base 01 and is connected to the main boiler 03 and the auxiliary boiler 04. In an optional embodiment of this embodiment, two dosing devices 12 are provided, which are respectively connected to the main boiler 03 and the auxiliary boiler 04. The dosing device 12 adds scale inhibitors and other agents to make it difficult for calcium, magnesium and other ions in the water to form scale, thereby avoiding deposition on the heating surfaces of the main boiler 03 and the auxiliary boiler 04, thereby improving the heat transfer efficiency of the main boiler 03 and the auxiliary boiler 04, reducing energy waste, and extending the service life of the main boiler 03 and the auxiliary boiler 04. In addition, the addition of corrosion inhibitors can form a protective film on the metal surface of the main boiler 03 and the auxiliary boiler 04, preventing dissolved oxygen, carbon dioxide, etc. in the water from corroding the metal of the main boiler 03 and the auxiliary boiler 04, thereby ensuring the structural integrity and safety of the main boiler 03 and the auxiliary boiler 04. In addition, the dosing device 12 can add alkaline agents as needed to adjust the pH value of the feed water to keep it within a suitable range to prevent acid corrosion, and also help maintain the chemical balance in the water to ensure that the water quality meets the requirements for the operation of the main boiler 03 and the auxiliary boiler 04.

[0037] Reference Figures 1 to 4 The main boiler group 003 and the auxiliary boiler group 004 also include a vacuum gauge group 6, a pressure gauge group 7, a pressure switch group 8, an inlet stop check valve 9 and a return water throttling orifice plate 10.

[0038] The vacuum gauge group 6 includes a main boiler vacuum gauge 61 and an auxiliary boiler vacuum gauge 62. The main boiler vacuum gauge 61 is connected to the main boiler feed water pump 3, and the auxiliary boiler vacuum gauge 62 is connected to the auxiliary boiler feed water pump 4. The pressure gauge group 7 includes a main boiler pressure gauge 71 and an auxiliary boiler pressure gauge 72. The main boiler pressure gauge 71 is connected to the main boiler feed water pump 3, and the auxiliary boiler pressure gauge 72 is connected to the auxiliary boiler feed water pump 4. The vacuum gauge group 6 and the pressure gauge group 7 are installed at the inlet and outlet positions of the main boiler feed water pump 3 and the auxiliary boiler feed water pump 4, respectively. The vacuum gauge group 6 is used to measure the pressure at the inlet of the main boiler feed water pump 3 and the auxiliary boiler feed water pump 4, usually expressed in the form of negative pressure. When the inlet pressure is too low, the suction performance of the main boiler feed water pump 3 and the auxiliary boiler feed water pump 4 may be reduced, or even cavitation may occur, thereby affecting the normal operation of the main boiler feed water pump 3 and the auxiliary boiler feed water pump 4. The pressure gauge group 7 is used to measure the pressure at the outlet of the main boiler feed pump 3 and the auxiliary boiler feed pump 4. By observing the readings of the pressure gauge group 7, the operator can intuitively understand whether the output pressure of the main boiler feed pump 3 and the auxiliary boiler feed pump 4 meets the requirements of the ship's boiler feed system. If the outlet pressure is too high or too low, it may indicate that the ship's boiler feed system has a fault or is operating abnormally. Therefore, the accurate indication of the vacuum gauge group 6 and the pressure gauge group 7 is crucial for timely detection and handling of problems.

[0039] Reference Figures 1 to 4 The pressure switch group 8 includes a main boiler pressure switch 81 and an auxiliary boiler pressure switch 82. The main boiler pressure switch 81 is connected to the main boiler feed water pump 3 and is arranged adjacent to the main boiler pressure gauge 71. The auxiliary boiler pressure switch 82 is connected to the auxiliary boiler feed water pump 4 and is arranged adjacent to the auxiliary boiler pressure gauge 72. Taking the working process of the main boiler pressure switch 81 as an example, when the ship boiler feed water device is operating normally, the main boiler feed water pump 3 is responsible for supplying water. When one of the main boiler feed water pumps 3 fails, the feed water pressure will drop rapidly. At this time, the main boiler pressure switch 81 will keenly sense the pressure change. When the pressure drops below the set threshold, the main boiler pressure switch 81 will immediately output a control signal to start another main boiler feed water pump 3. This process is completed almost instantly, ensuring the continuity of the feed water supply and avoiding the serious impact on the operation of the main boiler 03 caused by the interruption of the feed water. This automatic switching function of the pressure switch group 8 greatly improves the reliability and safety of the ship boiler feed water device.

[0040] Reference Figures 1 to 4The inlet stop check valve 9 includes a hot well inlet stop check valve 91, a main boiler inlet stop check valve 92 and an auxiliary boiler inlet stop check valve 93. The inlet stop check valve 9 is arranged on the main water pipe 1 and the auxiliary water pipe 2; the return water throttling orifice 10 is arranged adjacent to the hot well inlet stop check valve 91. In the process of water supply backflow, the pressure of the return water is usually high. If the return water is directly introduced into the hot well 02, it may have an adverse effect on the liquid level control and system stability of the hot well 02. The return water throttling orifice 10 effectively reduces the return pressure by utilizing the throttling resistance increase principle. At the same time, the return water throttling orifice 10 can also adjust the flow conditions of the main boiler feed water pump 3 and the auxiliary boiler feed water pump 4 by changing the characteristics of the pipeline. This adjustment method can not only optimize the operating efficiency of the main boiler feed water pump 3 and the auxiliary boiler feed water pump 4, but also flexibly adjust the water supply according to the needs of the ship boiler feed water system, ensuring that the operation of the ship boiler feed water device is more stable and efficient.

[0041] Reference Figures 1 to 5 , taking the water supply process of the auxiliary boiler feed pump 4 as an example, the operation mechanism of the ship boiler feed device can be more clearly understood. In this embodiment, the ship boiler feed device has a total of two auxiliary boiler feed pumps 4. One of the auxiliary boiler feed pumps 4 is the main operation pump, and the other auxiliary boiler feed pump 4 is the standby pump. During normal operation, the main operation pump extracts qualified condensed water from the hot well 02. After the condensed water is pressurized by the main operation pump, it is sent to the auxiliary boiler 04 for use through the control of the auxiliary boiler inlet stop check valve 93. During the operation of the auxiliary boiler 04, excess steam will be generated, and this steam will directly flow back to the hot well 02 for cooling so that it can be recycled again. However, there may be some unqualified water in the hot well 02. This water will also pass through the operation of the main operation pump, through the return pipe and the return water throttling orifice 10, and be controlled by the hot well inlet stop check valve 91, and finally flow back to the hot well 02 for treatment. In this process, the auxiliary boiler vacuum gauge 62 and the auxiliary boiler pressure gauge 72 monitor the inlet and outlet pressures of the main operation pump respectively to ensure that the main operation pump is in good operating condition. The auxiliary boiler pressure switch 82 is ready to start the standby pump at any time when the main operation pump fails to ensure the continuous supply of feed water. The return water throttling orifice plate 10 plays an important regulating role in the return process to ensure that the pressure and flow of the ship boiler feed water device remain within a reasonable range.

[0042] When starting the main boiler feed pump 3 and the auxiliary boiler feed pump 4, the operator needs to pay special attention to some key steps. First, the inlet valve should be opened to ensure that the main boiler feed pump 3 and the auxiliary boiler feed pump 4 can smoothly inhale the fluid. At the same time, the outlet valve should be closed to prevent the motor from generating too high a starting current due to excessive load at the moment of starting, thereby protecting the motor from damage. After the main boiler feed pump 3 and the auxiliary boiler feed pump 4 are started, the operator needs to closely observe the changes in the outlet pressure. Once the outlet pressure is stable, the outlet valve can be slowly opened to gradually adjust the flow and head so that the main boiler feed pump 3 and the auxiliary boiler feed pump 4 can smoothly enter the normal operation state. In addition, it should be noted that the idling time of the main boiler feed pump 3 and the auxiliary boiler feed pump 4 should not be too long without fluid discharge, otherwise it will cause the water temperature in the main boiler feed pump 3 and the auxiliary boiler feed pump 4 to rise, which may cause cavitation or other faults, affecting the service life and operation efficiency of the main boiler feed pump 3 and the auxiliary boiler feed pump 4.

[0043] The ship boiler water supply device of the present invention significantly reduces the number of pipeline layout and outfitting parts in a limited space through optimized design, realizes one-time hoisting and installation, greatly improves the accuracy of pipeline connection, and enhances the integration degree of the ship boiler water supply device.

[0044] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention.
