Description

Technical Field

[0001] This utility model relates to the technical field of municipal solid waste incineration equipment, and in particular to a highly clean waste incineration subseawater cooling system. Background Technology

[0002] Freshwater resources are precious in coastal areas, and with the expansion of industry along the coast, the application of subsea water for industrial cooling is becoming increasingly widespread. However, compared to freshwater, subsea water cooling water has higher salinity and more complex microbial communities. Using it as cooling water in waste-to-energy incineration may lead to metal corrosion and scaling in pipelines, affecting incineration efficiency and equipment safety. Furthermore, due to its high salinity, subsea water concentrates upon heating during cooling, exacerbating salt scaling and significantly impacting the long-term stable operation of waste incineration systems, necessitating improvements. Utility Model Content

[0003] To address the shortcomings of the aforementioned technologies, this utility model provides a highly clean waste incineration subseawater cooling system, comprising a subseawater inlet pipe, a subseawater purification tower, and a cooling water delivery pipe. The subseawater inlet pipe and the cooling water delivery pipe are respectively installed on the top and bottom side walls of the subseawater purification tower. The subseawater purification tower is equipped with purification devices both inside and outside. Each purification device includes a neutralization liquid tank, a sedimentation collection tank, several transfer pumps, several solenoid valves, a drive cylinder, a movable filter screen, a connecting rod, a neutralization liquid inlet pipe, and a sedimentation discharge pipe. The neutralization liquid tank is connected to the interior of the subseawater purification tower via the neutralization liquid inlet pipe and the transfer pumps. The sedimentation collection tank is connected to the interior of the subseawater purification tower via the sedimentation discharge pipe, and a solenoid valve is installed on the sedimentation discharge pipe. The drive cylinder is located at the top of the subseawater purification tower. The movable filter screen is located inside the subseawater purification tower and connected to the piston rod of the drive cylinder via the connecting rod. The shape and size of the movable filter screen match the inner wall of the subseawater purification tower. A transfer pump is also installed at the connection point between the cooling water delivery pipe and the subseawater purification tower.

[0004] The above technical solution involves a purification device including a neutralizing liquid tank, a sedimentation collection tank, several transfer pumps, several solenoid valves, a drive cylinder, a movable filter screen, a connecting rod, a neutralizing liquid inlet pipe, and a sedimentation discharge pipe. Submarine seawater is introduced into the purification tower through an inlet pipe, and then neutralizing liquid is injected into the tower according to a specific ratio. Impurities in the submarine seawater react chemically with the neutralizing liquid to produce sediment. After the reaction and settling, the drive cylinder activates, controlling the movable filter screen to move downwards to below the cooling water delivery pipe. At this time, the transfer pumps on the cooling water delivery pipe start, transferring the neutralized submarine seawater out. During the transfer process, the sediment at the bottom is separated by the filter screen. When the water level drops to the bottom of the cooling water delivery pipe, the transfer of submarine seawater is complete. Then, the solenoid valve on the sedimentation discharge pipe opens, discharging the sediment into the sedimentation collection tank. After the sediment is discharged, new submarine seawater can be introduced and the above steps repeated. This process effectively removes impurities from the submarine seawater, minimizing metal corrosion and scaling in the pipes, and reducing the impact on waste incineration efficiency and equipment safety.

[0005] A further feature of this invention is that the cooling water conveying pipeline is also equipped with a dynamic salt concentration adjustment device, which includes a freshwater tower, a water pump, a neutralization pipeline, a neutralization tower, and a salinity meter. The cooling water conveying pipeline is connected to the neutralization tower, and the freshwater tower is connected to the neutralization tower through the water pump and the neutralization pipeline. The salinity meter is installed inside the neutralization tower and is electrically connected to the water pump through a PLC controller.

[0006] By adopting the above technical solution, a dynamic salt concentration adjustment device is also installed on the cooling water conveying pipeline. The dynamic salt concentration adjustment device includes a freshwater tower, a water pump, a neutralization pipeline, a neutralization tower, and a salinity meter. The cooling water conveying pipeline is connected to the neutralization tower, and the freshwater tower is connected to the neutralization tower through the water pump and the neutralization pipeline. The salinity meter is installed inside the neutralization tower and is electrically connected to the water pump through a PLC controller. After the sub-seawater with impurities removed is transferred into the neutralization tower, the salinity content in the sub-seawater is monitored in real time by the salinity meter. Based on the comparison of the salinity content with the installed threshold, the water pump is controlled to start and inject freshwater from the freshwater tower into the neutralization tower to neutralize the sub-seawater. After the salinity content reaches the standard, it is used as cooling water. This avoids excessively high salt concentration, which can cause scale precipitation during use and thus avoids affecting the long-term stable operation of waste incineration.

[0007] A further feature of this invention is that a cleaning water pipe is provided on the top side of the subsea water purification tower near the neutralizing liquid inlet pipe, and a cleaning nozzle is provided at the end of the cleaning water pipe.

[0008] By adopting the above technical solution, since a cleaning water pipe is provided on the top side of the subsea water purification tower near the neutralizing liquid inlet pipe, and a cleaning nozzle is provided at the end of the cleaning water pipe, the movable filter screen can be sprayed and cleaned regularly after long-term operation, thus avoiding the problem of decreased filtration effect caused by clogging of the movable filter screen.

[0009] A further feature of this invention is that a mounting frame is provided above the sedimentation collection tank, and the subsea water purification tower is mounted on the mounting frame.

[0010] By adopting the above technical solution, since there is an installation frame above the sedimentation collection tank and the subsea water purification tower is installed on the installation frame, the discharge of sediment is more complete, and at the same time, the sediment can be prevented from clogging the sedimentation discharge pipe.
