Technical solution for vacuum drainage system in prisons
Hangzhou Juchuan Environmental Technology Co., LTD
I. Project Background
In the construction and renovation of correctional facilities such as prisons, detention centers and drug rehabilitation centers, special requirements such as high safety, water conservation, ease of control and maintenance have been put forward for the drainage system. The traditional gravity drainage system has the following main problems when applied in these places:
1. Risk of intercommunication of drainage - the drainage branch pipes of each cell are interconnected and can be exploited to pass contraband, clog pipes and disrupt order;
2. High water consumption and difficult management - ordinary toilets use 6 to 9 liters each time, which not only wastes water but also makes it difficult to monitor usage.
3. High rate of pipe clogging - the drainage system is prone to scaling and clogging after long periods of operation, and maintenance requires breaking walls and floors, disrupting regulatory order;
4. Difficult to renovate - Traditional gravity drainage requires a continuous slope, and expansion or renovation is severely restricted by the building structure.
To address these issues, the vacuum drainage system provided by Juchuan Environmental Protection is a new type of drainage solution that integrates water conservation, safety, intelligence and flexibility, and is particularly suitable for high-security places such as correctional facilities, prisons, detention centers and supervision centers.
2. System Principles
A vacuum drainage system is a closed drainage system that uses the difference between vacuum negative pressure and atmospheric pressure to transport sewage. When the user presses the flush button, the control system opens the vacuum valve, and atmospheric pressure quickly sucks the dirt in the toilet into the vacuum network and sends it to the vacuum collection tank; The vacuum pump maintains negative pressure in the system to ensure fast and stable delivery. When the water level in the collection tank reaches the set value, the sewage is discharged through the discharge pump into the municipal sewage network or sewage treatment station. The process is fully automatic, fast, low-noise, odorless, and the flushing volume is only about 2 liters per time, which is a quarter of that of traditional systems.
3. System Composition
1. Vacuum toilet: Flush ≤2L/ time, made of stainless steel explosion-proof or high-strength ceramic, explosion-proof, splash-proof and sound-proof.
2. Vacuum valve unit: Opens instantly upon receiving the control signal and uses the vacuum difference to draw the wastewater into the main pipe.
3 Vacuum pipe network: Smaller pipe diameter (DN40 to DN75), no slope required, flexible layout.
4. Vacuum collection center: Composed of vacuum tank, vacuum pump set, sewage discharge pump and control cabinet.
5. Intelligent control system: It is equipped with remote monitoring of valves, flushing counting, and alarm linkage functions, and can be centrally managed.
4. System Advantage Analysis
1. Water and energy saving: Only 1L per flush saves about 70% of water resources;
2. Safety control: Separate discharge from each cell to prevent the transfer of contraband;
3. Manageable: Limits on the number of flushes or time periods;
4. Easy to maintain: The pipe network is not prone to clogging, and fault points can be precisely located;
5. Hygienic and environmentally friendly: No splashing, no odor, improving environmental hygiene.
V. Analysis of water conservation and economic benefits
A medium-sized prison with 500 inmates as an example:
If each person uses the toilet 10 times a day, the vacuum system flushes 2 liters per flush, and the traditional system flushes 6 liters, then the annual water savings are:
(6L - 2L) × 10 times × 500 people × 365 days = 7,300,000 liters (about 7,300 tons)
Based on water and sewage charges of 6 yuan per ton, the annual cost savings amount to approximately 43,800 yuan. Combined with maintenance and construction savings, the total economic benefits increase by approximately 20% to 30%.
6. Security and Control advantages
1 Prevent cross-room communication and stop the passing of contraband;
2. The flushing function can be turned off in zones for easy security checks;
3. The system can record the number of flushes and locate blocked rooms;
4. Prevent collective flushing from damaging the pipelines;
5. Splash-free flushing ensures environmental hygiene.
7. Design and construction services
Juchuan Environmental Protection provides full-process services from design to operation and maintenance:
1. Scheme design stage: Provide system selection, piping advice and hydraulic calculation;
2. Equipment supply and installation guidance: Provide commissioning and installation training;
3. System commissioning and acceptance: Complete system testing and acceptance reports;
4. Operation and maintenance training and after-sales: Provide operation training, remote diagnosis and regular maintenance.
