Application of vacuum drainage system of Juchuan ship
Background of ship drainage project
At present, the sewage system of domestic ships mainly adopts vertical pipes, and the layout of toilets is greatly limited, even some toilets far from the collection box have to be cancelled. In addition, due to the large amount of scour water, the volume of sewage collection tank required by the ship is relatively large, and the space occupied by the ship is large, especially the ships that need to navigate or park in the restricted sea area for a long time, which will inevitably result in the reduction of the effective loading volume.
Compared with the traditional gravity pipeline, the vacuum blowdown system can not only save water and protect the environment, but also has the advantages of relatively small pipe diameter, convenient pipe network installation, not easy to block, good economic performance, etc. it has been widely used in the field of aircraft, ships, trains and other transportation. For ships with precious space, the advantages of vacuum blowdown technology are especially obvious. The matching vacuum equipment and accessories technology is becoming more and more mature. Only in daily life, pay attention to prevent foreign matters from blocking and carry out simple maintenance, the vacuum blowdown system can operate reliably. With the improvement of people's living comfort and consideration of water conservation, the vacuum sewage system will gradually replace the gravity sewage system as the ship sewage system.
Introduction to Marine vacuum
drainage systems
Vacuum drainage system is a completely closed negative pressure system, relying on the role of pressure difference, the sewage and the surrounding gas is sucked into the vacuum tube at high speed and then discharged to the sewage treatment system through the CAM pump in time; The sewage does not remain in the pipeline, and the real-time discharge of sewage is realized. The intelligent central vacuum drainage system can effectively overcome many shortcomings of the traditional drainage system.
Comparison of ship vacuum and gravity blowdown
Comparison program | Traditional gravity sewage system | Vacuum blowdown system |
Design | Limited by hydraulic gradient, it is difficult to lift sewage, or it is necessary to lift pumps and structures Inconvenient design in the same floor drainage design | Vacuum suction, not affected by gravity, can lift sewage at will Drainage pipeline can be arranged as required, flexible and changeable |
Pipe diameter | Large diameter, high cost and large-scale excavation Slow flow rate and easy scaling Pipeline laying takes up a large space and cannot bypass obstacles at will Deep excavation of pipe trench, long construction period, great difficulty and high cost | The vacuum pipe diameter is small, usually 50-200mm, which can be made of PVC or PE with low cost Fast flow rate, self flushing ability, not easy to scale The pipeline can be laid flexibly, the direction is not limited by the terrain, and the obstacles can be easily bypassed Shallow buried depth, small construction earthwork, simple and economic construction |
Install and repair | Complicated installation, large quantities of work and imperceptible leakage | The installation is relatively small and the maintenance is simpler. The pipeline is in a vacuum state and there is no leakage of transmission medium |
Odor problem | The pipe network system is semi open, with poor sealing performance, odor escaping, breeding mosquitoes and flies | The pipe network is negative pressure and completely closed, and the odor will not escape |
Reconstruction of existing buildings | Difficult construction, high investment and long construction period | Easy to expand, easy to construct and short construction period |
Vacuum system ship application scenarios
Features of vacuum drainage system for Juchuan ships
The flushing water volume of the toilet is small, and the single flushing water volume is about 1.5L
The sewage pipe laying is not affected by gravity, has the sewage vertical lifting capacity, does not need the large slope design of the conventional gravity drainage system for the horizontal laying of the pipe, and is not affected by the inclination or turbulence of the hull.
The pipeline installation is very flexible, which can easily avoid obstacles and allow upward lifting of the laying, thus reducing the installation time and saving the installation cost
The blowdown pipe diameter is small, and the pipeline is allowed to be laid horizontally for a long distance, which reduces the setting of the riser.
The layout of toilet is relatively loose, which facilitates the overall layout design of the system
Full negative pressure closed system, no odor leakage
Improve the comfort of toilet environment, clean and odorless
The total amount of sewage produced by the system is reduced, and the cost of subsequent sewage treatment is reduced
Juchuan environmental protection vacuum drainage system features
Juchuan Environmental Protection has produced more than 3600 sets of vacuum drainage system, has been a lot of use, after years of experience accumulation and improvement, the product has been very mature and stable. It has the characteristics of high equipment integration, compact design, small footprint and convenient installation. Also carried out Chinese localization production, can stably control the quality and price of products. Juchuan vacuum unit in the design of the full consideration of the stability of the equipment, the use of redundant backup design, vacuum pump groups backup each other, sewage pump groups backup each other, the use of different sensors for backup, and between the pump groups alternate work, while strictly control the pump group start frequency, extend the life of the pump station. At the same time, the system adopts high reliability industrial PLC control system, reliable operation, high degree of automation.
