Indoor vacuum collection and discharge system

Project background:

Application background of indoor vacuum blowdown Technology

There are many problems if apply the traditional gravity drainage method in the new large space, long-apan and large-scale underground buildings:

• The slope of the pipeline affects the indoor floor height, thus hinders the space utilization and decoration effect

• Increase of civil structure cost caused by sewage lifting

• The pipe diameter is enlarged step by step to reduce the flow rate and cause impurities to accumulate and block

• Structural beams and columns, professional pipelines and other restrictions on the direction of drainage pipes

• Health and safety problems caused by leakage caused by defects of pipe and construction quality

• Underground civil air defense space is used, no holes are allowed, and gravity flow pipelines cannot be arranged

• The gravity flow in the underground space is easy to cause the problems of poor drainage, full of odor, and the breeding of flies and mosquitoes

• For the reconstruction of existing buildings, gravity flow is difficult to expand, construction is difficult, investment is high, and the period is long

What is a vacuum drainage system?

Juchuan vacuum drainage system provides unlimited freedom and flexibility in building layout, design and construction, pumping sewage through vacuum negative pressure pipes to vacuum units and then discharging to sewage treatment facilities. Juchuan vacuum vacuum drainage system provides architects and designers with the freedom to locate the pipeline "at will", allowing an open building environment, flexible spatial planning, can realize the rapid design of drainage system, rapid transformation, construction, solve the problem of sewage, and maximize the use of building space.

Juchuan vacuum drainage system, through its system of negative pressure suction, closed pipe characteristics, to prevent indoor air pollution and virus transmission, simply put, for the people in the building to provide a better level of health conditions, improve the quality of life. The vacuum toilet of Juchuan vacuum drainage system can save water significantly, save 90% of water, save water charges, save the construction of sewage treatment facilities and sewage treatment costs, can realize the same layer drainage without a large number of lifting devices, the system has online monitoring device, when the sewage leakage can be found to locate the fault point in time and eliminate the fault. Can greatly reduce the difficulty of maintenance and maintenance costs.

Flexible collection of all kinds of sewage

When it comes to our vacuum drainage technology, the first thing we always mention is the extraordinary ability to meet all requirements.

Through two key features, we can adapt to every design task:

• We can lift sewage up to 4-7 meters

• he transfer sewage has the climbing ability to transport sewage over long distances within the horizontal range without the need to increase the lifting pump.

This flexibility is ideal for every designer: bathrooms can be placed where they need them, floors can be designed for completely different uses, and reconfiguration doesn't affect the rest of the building.

Simply put: Vacuum drainage systems provide the best sewage collection solution for your building!

Effectively improve indoor sanitation

Although the design and construction of vacuum drainage system is very flexible, whether it can improve the sanitary environment in the building is also an important factor to be considered in the drainage system. All traditional gravity water flusher will produce virus-containing aerosols in the air when flushing the toilet, bringing odor, environmental pollution, and the risk of virus transmission.

It is well known that the recoil of conventional toilets can cause the spread of bacteria and viruses in indoor air. But in fact, this also happens in washbasins and showers, when a large amount of sewage enters the drainage pipe, it will cause pollution in the sewer air to break through the trap, back into the room, and spread all kinds of bacteria and viruses.

This is not the case with our vacuum toilets, which rely on the mechanical closure of the diaphragm valve.

The vacuum pipe is a closed negative pressure pipe. When the vacuum toilet flushes, it only sucks out the sewage and carries away 60 liters of contaminated air. No splashing, no aerosol transmission -- a common way for viruses to spread. Washbasins and showers are separated by mechanical diaphragm valves and drains without recoil, effectively reducing the spread of bacteria.

In short, vacuum drainage systems can provide a better sanitary condition for buildings and improve the business environment!

Lower construction and operation costs

Vacuum drainage system can be long-distance transmission, no need to slope and increase the lifting device, the number of equipment is small, while maximizing the use of space, can effectively save the cost of civil construction, ceiling decoration and equipment. Cost saving at the same time, improve the efficiency of construction projects.

Vacuum drainage pipe laying flexible, can shorten the design, construction cycle, save manpower and management costs.

Vacuum urinals can effectively save water by 90%. For commercial centers, high-speed railway stations and airports with frequent use of toilets, they can greatly save water charges and the construction and treatment costs of sewage treatment facilities at the back end, saving and environmental protection.

The whole drainage system, only the vacuum unit part has a vent pipe, a sewage pipe, reduce the municipal connection cost, the system also adds an online monitoring system, can detect equipment failure in time, effectively reduce the difficulty and cost of operation and maintenance.

Simply put: vacuum drainage system for your project effectively save construction and operation costs!

Application field of vacuum collection and discharge system

Compared with the traditional gravity drainage system, the vacuum drainage system not only can effectively save water and protect the water environment, but also has the advantages of the pipe network not limited by the terrain, convenient installation, not easy to block, relatively small pipe diameter, good economic performance and so on.

Application of indoor vacuum drainage

• Fixed space: underground commercial space, subway, environmental toilet, shopping mall / office building, commercial reconstruction, old urban reconstruction.

• Mobile space: train, high-speed rail, ship, offshore oil drilling platform, container barracks, etc.

Outdoor vacuum drainage application

Water source protection area, rural sewage collection, villa sewage collection, industrial zone sewage collection, river sewage treatment, etc.

Application of vacuum drainage:

At present, the mainstream application is mainly divided into indoor vacuum drainage and outdoor vacuum drainage, which make use of the different characteristics of vacuum drainage in different application scenarios.

Indoor vacuum drainage is mainly used in building drainage, from the current situation, the main application of underground space development drainage, underground toilet, underground commercial catering drainage, building on the same floor drainage, hospital drainage on some special occasions (for example, infection department, radiology department, negative pressure ward, etc.).

Underground space, underground toilet, underground commercial catering vacuum drainage application

The situation of underground space is more complicated, many drainage points have drainage difficulties, if the traditional gravity flow is used, the cost of civil construction may be relatively high, and the vacuum drainage pipeline is flexible, which can save a lot of civil construction costs. In addition, the underground space is also a closed space, the underground dining and toilet sewage is easy to produce odor, causing air pollution in the indoor space, affecting the indoor environment, and causing serious impact on the underground business environment, which is also an important factor for the underground space to use vacuum drainage. Finally, the underground commercial catering drainage is easy to block the problem, because the catering wastewater contains heavy grease, in the case of cooling and slow flow rate will solidified on the drainage pipe wall, with the increase, will cause the drainage pipe network blockage, maintenance trouble. And the grease in the pipe is easy to breed bacteria, resulting in odor overflow, breeding mosquitoes and flies, the vacuum drainage situation is much better, because the vacuum drainage uses the gas-liquid two-phase drainage method, the sewage flow rate is high (4-7 meters/second), the flushing power is strong, it is not easy to block. Therefore, in addition to the underground toilet with vacuum drainage, in fact, more and more underground commercial catering oily wastewater, but also gradually began to use vacuum drainage system to collect.

Hospital vacuum drainage application

The hospital has always been a particularly complex building in civil buildings, and the drainage pipe must have many equipment rooms, clean areas, wards must be bypassed, can not take the drainage network, so the traditional gravity flow whether it is designed, construction will be more difficult, and the cost is high.

In addition, the sewage composition of the hospital is very complex, and there are often toxic, harmful, radioactive, heavy metals and other sewage, which needs to be collected and discharged separately, and can not be leaked, otherwise it will cause serious pollution risk. Therefore, the vacuum drainage pipeline is flexible, the pipeline is closed, clean and sanitary characteristics, for the hospital this special complex drainage situation, is a more ideal drainage method.

Building transformation of the same floor drainage

For buildings that are needed, there is a need for a change of use, such as from non-catering to catering and from offices to hotels. In this special case, there is no reserved drainage conditions, so it must be a large area of the same layer drainage, in this case, the vacuum drainage system transformation is more convenient, the vacuum drainage pipe can be as flexible as the water pipe layout, so it is very convenient to complete the drainage transformation.

Other indoor vacuum drainage system applications

Indoor vacuum drainage application scenarios are very many, can not enumerate one by one, this only roughly enumerate its application scenarios.

Supermarkets, fresh stores, the store inside the condensate, cooked food area, seafood area will have a lot of wastewater, and the layout of the supermarket is often adjusted, so now there are some fresh stores, the supermarket uses vacuum drainage system.

Underground civil air defense space, this main civil air defense space can not be worn down, must be drained on the same layer.

In buildings in arid and water-scarce areas, vacuum toilets can save water significantly. Some areas will carry out water-saving transformation, and some vacuum drainage systems are also adopted.
