Description
Technical Field
The utility model relates to a water well sealing structure for CSSD in hospitals, in particular to a special cooling water well sealing structure for the CSSD in hospitals outdoors.
Background
The hospital disinfection supply Center (CSSD), also called "central (disinfection) supply", is a department in the hospital that undertakes the cleaning, disinfection, sterilization and supply of sterile items of all reusable medical instruments, instruments and items for each department. The waste water discharged from the CSSD interior mainly comprises 3 types: 1. sewage in the decontamination area is soaked in various waste water discharged by a sewage soaking tank, a cleaning tank, a full-automatic cleaning machine, an ultrasonic cleaning machine, a large-scale full-automatic vehicle disinfection cleaning machine, an eye washer and the like; 2. preparing various back washing and back washing regeneration wastewater discharged between pure water; 3. the waste water discharged from a pulse vacuum sterilizer, a medical boiling sterilizer and the like in the packaging and sterilization area is inspected. Wherein, the discharge temperature of the first two kinds of waste water is not high, and the waste water contains medical detergent, disinfectant, inorganic salt, other solid pollutants and the like; the wastewater discharged from the type 3 pulse vacuum sterilizer and the like is mainly high-temperature wastewater.
According to the regulations of the current national design standard GB 50015-plus-water-discharge design standard 2019: the sewage with the water temperature of more than 40 ℃ can be discharged to an outdoor sewage pipe network after being subjected to cooling treatment; the drainage of medical sterilization equipment, the drainage pipe of the equipment and a domestic drainage pipeline system adopt an indirect drainage mode. In order to meet the requirements of national design standards, an air partition is mostly arranged between a water outlet and a drainage pipeline of the equipment of the pulse vacuum sterilizer, and a sewage discharging and cooling pond is arranged indoors. When equipment drainage, because the drainage temperature is higher, and is mostly two-phase steam-water, can be at indoor scattered steam, influence the cleanliness factor of indoor air. For this reason, some hospital disinfection supply Centers (CSSD) have to eliminate the air separation between the facility drain and the drain line and instead connect them directly. Indeed, whether the air separation is provided indoors as required by regulations or the connection is direct, it is disadvantageous for the disinfection supply Center (CSSD).
Disclosure of Invention
The utility model aims to provide a special cooling water seal well structure for a CSSD (clean water storage) outdoor unit of a hospital, which meets the regulation of GB50015-2019 'design standard for water supply and drainage of buildings'.
In order to achieve the purpose, the utility model can adopt the following technical scheme:
the utility model relates to a special cooling water seal well structure for a CSSD (compact disc SD) outdoor of a hospital, which comprises a vertical well arranged outdoors and a cover plate hermetically arranged on the mouth of the vertical well, wherein an overflow ridge is transversely arranged on the bottom plate of the vertical well, and separates the vertical underground part to form a mixing tank and a water inlet tank; the anti-mixing retaining wall is longitudinally arranged on the water inlet tank bottom plate and divides the water inlet tank into a normal-temperature wastewater water inlet tank and a high-temperature wastewater water inlet tank, and the height of the anti-mixing retaining wall is greater than that of the overflow ridge; a drain pipe communicated with a hospital underground sewage pipe network is arranged at the bottom of the mixing tank; and the normal-temperature wastewater inlet and the high-temperature wastewater inlet are respectively arranged at the lower parts of the normal-temperature wastewater inlet tank and the high-temperature wastewater inlet tank.
Further, vertical well lateral wall upper portion is provided with normal atmospheric temperature waste water inlet tube and high temperature waste water inlet tube respectively, the mouth of pipe of normal atmospheric temperature waste water inlet tube and high temperature waste water inlet tube communicates downwards respectively has 90 return bends, the mouth of pipe of 90 return bends is located the lower part of normal atmospheric temperature waste water intake groove and high temperature waste water intake groove respectively to form normal atmospheric temperature waste water inlet and high temperature waste water inlet.
Preferably, the height of the overflow ridge is respectively greater than the height of the normal-temperature wastewater inlet and the height of the high-temperature wastewater inlet by 100mm, so that effective water seal protection is formed; the height of the anti-mixing retaining wall is greater than the height of the overflow ridge by 100 mm.
The advantages of the utility model are embodied in the following aspects:
1. by adopting a three-grid design, a normal-temperature wastewater drainage pipe and a high-temperature wastewater drainage pipe from a disinfection supply Center (CSSD) respectively enter a cooling water seal well, and are separated by an anti-mixing retaining wall in the cooling water seal well to form respective relatively independent water seals so as to avoid mutual doping of the two.
2. The overflow ridge is coordinated with the elevation of the normal-temperature wastewater inlet and the elevation of the high-temperature wastewater inlet to form an effective water seal.
3. Set up cooling water seal well outdoors, the sewage in decontamination area soaks drainage facilities such as groove, washing tank, and the lower part can no longer set up trap (S type trap or P type trap), has both satisfied the regulation of relevant design standard, also does benefit to indoor drainage smoothly.
4. The traditional pollution discharge cooling pool needs to be provided with a special cold water supply pipeline, and a certain amount of cold water (usually tap water) needs to be consumed during cooling. According to the design, the normal-temperature waste water with large water discharge (namely the 1 st and 2 nd waste water discharged from the CSSD inside accounts for more than 80% of the water used in the disinfection supply center) and the high-temperature waste water with small water discharge (namely the 3 rd waste water discharged from the CSSD inside accounts for no more than 5% of the water used in the disinfection supply center) can be directly discharged after being mixed and cooled in the cooling water seal well, and the water resource is saved.
