Description

Technical Field

[0001] The present application relates to the technical field of ship desulfurization circulation systems, and more specifically, to a modularized ship desulfurization circulation device and system. Background Art

[0002] In traditional designs, due to the large size of the equipment in the desulfurization circulating water system, the conventional desulfurization circulating water system design usually arranges the circulating water pump and the desulfurization circulating water cooler separately. This not only increases the number of hoisting operations, pipeline materials, and construction periods, but also fails to ensure construction safety.

[0003] Taking a container ship as an example, the 4 pumps for desulfurization circulating water are hoisted separately, using independent bases, and there are numerous connecting pipes. Hoisting and installation both consume a large amount of manpower and material resources. Even during commissioning, it can only start after the system integrity is completed, and the schedule is arranged later, which is not conducive to controlling the production cycle. Summary of the Invention

[0004] The purpose of the present application is to provide a modularized ship desulfurization circulation device and system, which realizes the integrated and modular design of ship desulfurization circulation-related equipment. It can be independently assembled and commissioned, and then hoisted and installed as a whole onto the ship, reducing the on-site commissioning workload, lowering the construction difficulty, and improving the construction efficiency.

[0005] In a first aspect, a modularized ship desulfurization circulation device is provided, including an outfitting frame and desulfurization equipment integrally installed on the outfitting frame. A hoisting part is provided on the outfitting frame; the desulfurization equipment includes a system pipeline, a desulfurization circulating pump, and a desulfurization circulating water cooler; the system pipeline is installed on the outfitting frame and includes a main inlet and a main outlet; a desulfurization circulating pump is arranged upstream of the system pipeline, and a desulfurization circulating water cooler is arranged downstream of the desulfurization circulating pump.

[0006] In an implementable solution, a parallel pipe section part is provided on the system pipeline upstream of the desulfurization circulating water cooler. The parallel pipe section part includes at least two pipelines, and each pipeline is provided with a desulfurization circulating pump.

[0007] In an implementable solution, multiple desulfurization circulating pumps and desulfurization circulating water coolers are uniformly arranged along the longitudinal extension direction of the outfitting frame.

[0008] In an implementable solution, the system pipeline is arranged at the edges on both transverse sides of the outfitting frame and extends longitudinally.

[0009] In an implementable solution, the outfitting frame includes a frame body and a grille structure installed on the frame body.

[0010] In an implementable solution, the grille structure extends transversely and is located between adjacent desulfurization circulating pumps and between the desulfurization circulating pump and the desulfurization circulating water cooler.

[0011] In an implementable solution, there are no obstructions in the upper space above the desulfurization circulating pump and the desulfurization circulating water cooler.

[0012] In an implementable solution, the skid-mounted ship desulfurization circulating device further includes a strengthening structure. The desulfurization circulating pump is connected to the outfitting frame through a number of strengthening structures, and the desulfurization circulating water cooler is connected to the outfitting frame through a number of strengthening structures.

[0013] In a second aspect, there is also provided a skid-mounted ship desulfurization circulating system, including the aforementioned skid-mounted ship desulfurization circulating device, and installed at a predetermined position on the ship; the ship desulfurization circulating system further includes a circulating water tank and a scrubbing tower; the circulating water tank buffers the liquid after scrubbing, and the circulating water tank is connected to the main inlet of the system pipeline of the skid-mounted ship desulfurization circulating device; the main outlet of the system pipeline of the skid-mounted ship desulfurization circulating device is connected to the scrubbing tower.

[0014] Compared with the prior art, the beneficial effects of the present application at least include:

[0015] For the skid-mounted ship desulfurization circulating device of the present application, by using the outfitting frame as a common base for each desulfurization device, the desulfurization circulating pump, the desulfurization circulating water cooler and related system pipelines are integrally installed on the same common base (i.e., the outfitting frame), reducing the pipeline length, improving the pipeline connection accuracy, reducing the space occupancy rate, and improving the ship integration and modularization level. At the same time, after the skid-mounted ship desulfurization circulating device integrates the pipelines and equipment, the maintenance points are concentrated, which is more convenient for future maintenance and repair work.

[0016] Moreover, due to the integrated design of the skid-mounted ship desulfurization circulating device of the present application, the installation and commissioning of the desulfurization circulating related equipment can be carried out independently of the ship construction, without the need to be carried out in the shipyard, and can be carried out in a more comfortable and clean environment, thus effectively reducing the quality problems caused by construction errors or environmental interference. After the commissioning is completed, since the system pipeline of the skid-mounted ship desulfurization circulating device of the present application is provided with an external main inlet and a main outlet, after the overall lifting and installation to the predetermined position of the ship, only the relevant equipment needs to be connected to the reserved interfaces on the device, without the need for repeated commissioning, thus also improving the construction efficiency and construction safety and reducing the construction difficulty.

Obviously, the described embodiments are some, but not all, of the embodiments of the present application. Usually, the components of the embodiments of the present application described and illustrated in the accompanying drawings here can be arranged and designed in various different configurations.

[0028] Accordingly, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the claimed present application, but merely represents selected embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts fall within the scope of protection of the present application.

[0029] As Figure 1 and Figure 8 shown, an embodiment of the present application provides a skid-mounted ship desulfurization circulation device, which includes an outfitting frame 1 and desulfurization equipment integrally installed on the outfitting frame 1. A lifting part (not shown in the figure) is provided on the outfitting frame 1, and the lifting part is used for lifting the skid-mounted ship desulfurization circulation device as a whole.

[0030] Among them, the desulfurization equipment includes a system pipeline 2, a desulfurization circulation pump 3, and a desulfurization circulating water cooler 4. The system pipeline 2 is installed on the outfitting frame 1 and includes a main inlet 21 and a main outlet 22. A desulfurization circulation pump 3 is provided upstream of the system pipeline 2, and a desulfurization circulating water cooler 4 is provided downstream of the desulfurization circulation pump 3.

[0031] For the skid-mounted ship desulfurization circulation device of the present application, by using the outfitting frame 1 as a common base for each desulfurization equipment, the desulfurization circulation pump 3, the desulfurization circulating water cooler 4 and the related system pipeline 2 are integrally installed on the same common base (i.e., the outfitting frame 1), reducing the pipeline length, improving the pipeline connection accuracy, reducing the space occupancy rate, and improving the ship integration and modularization level. At the same time, after the pipeline and equipment of the skid-mounted ship desulfurization circulation device are integrated, the maintenance points are concentrated, which is more convenient for future maintenance and repair work.

[0032] Moreover, due to the integrated design of the skid-mounted ship desulfurization circulation device of the present application, the installation and commissioning of the desulfurization circulation-related equipment can be carried out independently of the ship construction, without the need to be carried out in the shipyard, and can be carried out in a more comfortable and clean environment, thus effectively reducing the quality problems caused by construction errors or environmental interference. After the commissioning is completed, since the system pipeline of the skid-mounted ship desulfurization circulation device of the present application is provided with an external main inlet and main outlet, after the whole is lifted and installed at the predetermined position of the ship, only the relevant equipment needs to be connected to the reserved interfaces on this device, without the need for repeated commissioning, thus also improving the construction efficiency and construction safety and reducing the construction difficulty.

[0033] In one embodiment, as Figure 8As shown in the figure, a parallel pipe section is provided on the system pipeline 2 upstream of the desulfurization circulating water cooler 4. The parallel pipe section includes at least two pipelines, and each pipeline is provided with a desulfurization circulating pump 3. The setting of multiple desulfurization circulating pumps 3, on the one hand, helps to improve the circulation efficiency by starting multiple desulfurization circulating pumps 3, and on the other hand, multiple desulfurization circulating pumps 3 are backup to each other, which helps to improve the system redundancy ability.

[0034] In this embodiment, as Figure 8 shown, a pneumatic butterfly valve A1 can be provided at the main inlet 21 of the system pipeline 2, and a pneumatic butterfly valve D2 can be provided at the main outlet 22. In each parallel pipe section where the desulfurization circulating pump 3 is installed, a manual butterfly valve B1 can be provided at the front end of the desulfurization circulating pump 3, and a pressure sensor B3, a check valve B4, and a manual butterfly valve B2 can be sequentially provided at the rear end of the desulfurization circulating pump 3. The manual butterfly valve B1 and the manual butterfly valve B2 can be used to select whether to connect the desulfurization circulating pump 3 in the current branch. The pressure sensor B3 can transmit the outlet pressure signal to the main control device to facilitate centralized monitoring of the operation status of the pump. At the same time, an inlet pressure gauge P31 can be provided at the inlet of the desulfurization circulating pump 3, and an outlet vacuum pressure gauge P32 can be provided at the outlet of the desulfurization circulating pump 3 to indicate the pressure values at the inlet and outlet when the desulfurization circulating pump 3 is working, so as to judge whether the working state of the pump is normal.

[0035] In this embodiment, as Figure 8 shown, between the parallel pipe section and the desulfurization circulating water cooler 4, that is, a manual butterfly valve C1 can be provided at the hot side inlet of the desulfurization circulating water cooler 4, and a manual butterfly valve C2 and a temperature sensor D1 can be sequentially provided at the hot side outlet of the desulfurization circulating water cooler 4. The temperature sensor D1 is used to remotely transmit the outlet temperature signal to the main control device to facilitate monitoring of the operation status.

[0036] In this embodiment, as Figure 8 shown, a pressure gauge P41 and a thermometer T41 can be provided on the cooling seawater inlet side (cold side inlet) of the desulfurization circulating water cooler 4, a pressure gauge P42 and a thermometer T42 can be provided on the cooling seawater outlet side (cold side outlet), a pressure gauge P43 and a thermometer T43 can be provided on the hot side inlet of the desulfurization circulating water cooler 4, and a pressure gauge P44 and a thermometer T44 can be provided on the hot side outlet of the desulfurization circulating water cooler 4, so as to monitor the temperature and pressure of the cold / hot side medium at the inlet and outlet, and facilitate personnel to control the operation status of the desulfurization circulating water cooler 4.

The circulating medium can be alkaline seawater containing NaOH. After the scrubbing seawater is sprayed and washed with the exhaust gas in the scrubber, it is discharged into the circulating water tank, then enters the system pipeline 2 through the pneumatic butterfly valve A1, and then through each branch pipe of the parallel pipe section, and successively passes through the manual butterfly valve B1, the desulfurization circulating water pump 3, the pressure sensor B3, the check valve B4, and the manual butterfly valve B2 and converges. It is transported to the hot side inlet of the circulating water cooler 4 through the manual butterfly valve C1, is discharged after being cooled by exchanging heat with the cooling seawater in the cooler, and is transported to the scrubber through the manual butterfly valve C2, the temperature sensor D1 and the pneumatic butterfly valve D2. Part of it is sent to the venturi branch pipe at the flue gas inlet to pre-cool the relatively hot flue gas and preliminarily absorb impurities such as Sox and carbon black particles, and the other part is sent to the main tower body for deep scrubbing treatment of the flue gas.

[0038] In one embodiment, as Figure 2 and Figure 3 shown, multiple desulfurization circulating pumps 3 and desulfurization circulating water coolers 4 are evenly arranged along the longitudinal extension direction of the outfitting frame 1.

And, as Figure 6 shown, after the skid-mounted ship desulfurization circulation device of the present application is installed on the ship, only transfer lifting lugs 6 are provided on the top wall of the cabin above the desulfurization circulating pump 3 and the desulfurization circulating water cooler 4 to facilitate the hoisting and maintenance of the desulfurization circulating pump 3 and the desulfurization circulating water cooler 4. Among them, Figure 7 the arrow direction in indicates the hoisting transfer path of the desulfurization circulating pump 3.

The desulfurization circulation pump 3 is connected to the outfitting frame 1 through a plurality of strengthening structures 5, and the desulfurization circulation water cooler 4 is connected to the outfitting frame 1 through a plurality of strengthening structures 5.

[0044] The skid-mounted ship desulfurization circulation device of the present application can be installed and debugged independently of the construction of the ship hull structure. First, assemble according to the mechanical structure and circuit structure of the skid-mounted ship desulfurization circulation device. Before the test, it is necessary to check and confirm the installation integrity and tightness of the pipeline system, check that the control box and wiring are installed completely and powered on, and check the normality of the individual functions of each device. Then, conduct a linkage test on the system pipeline 2, the desulfurization circulation pump 3, the desulfurization circulation water cooler 4, and each valve and sensor. After there is no problem, hoist the whole device to the predetermined position of the ship, connect the reserved interface of the system pipeline 2 to the corresponding equipment on the ship, and connect the electrical circuit to the ship circuit to complete the debugging and installation of the skid-mounted ship desulfurization circulation device.
