After the laboratory is put into use, due to the complex internal environment of the laboratory, it will to some extent shorten the service life of the instruments, equipment, and experimental benches. In order to improve scientific research technology, it is necessary to renovate and design the laboratory. So how to carry out laboratory renovation on the basis of existing laboratories? What design details need to be paid attention to during the laboratory renovation process?
1、 Laboratory safety design
Ventilation system: A good ventilation system is an important component of any laboratory, especially when dealing with chemicals and harmful gases. The laboratory should be equipped with efficient exhaust cabinets and ventilation ducts to ensure that harmful gases and volatile substances can be discharged from the laboratory in a timely manner. Using a local exhaust system to directly capture the source of pollution and further improve ventilation efficiency. This is a very important part of laboratory renovation.
1. Fire protection system: The fire protection system in the laboratory must be comprehensive and effective. In addition to fire extinguishers, the laboratory should also install smoke alarms, emergency evacuation routes, and automatic sprinkler systems. Fire doors and fire rolling shutters should also be installed in important areas to prevent the spread of fire. These measures need to be considered during laboratory design.
2. Emergency eye wash and shower equipment: In chemical laboratories or areas handling hazardous substances, emergency eye wash and shower equipment are essential. These devices should be placed in prominent and easily accessible locations to ensure that laboratory personnel can quickly use them in the event of an accident. When renovating the laboratory, the installation positions of these equipment need to be designed and arranged reasonably.
3. Explosion proof design: In laboratories handling flammable and explosive substances, special attention should be paid to explosion-proof design. All lighting fixtures, appliances, and switches should adopt explosion-proof models and ensure that the electrical equipment in the laboratory meets relevant explosion-proof standards.
2、 Laboratory design layout
1. Functional zoning: Functional zoning based on different experimental properties is an important principle in laboratory layout. For example, separating the chemical experimental area, biological experimental area, and physical experimental area to avoid cross contamination and interference. Each functional area should have clear division and identification, so that experimenters can quickly find the required equipment and materials. This is a special part that needs to be done during laboratory renovation.
2. Channel design: The channels inside the laboratory should be spacious and unobstructed, ensuring easy access for personnel and equipment. The channel design should consider the need for emergency evacuation to avoid congestion in emergency situations.
3. Workbench height and layout: The design of the workbench should comply with ergonomic principles to ensure that experimenters can maintain a comfortable posture during prolonged operations. The height of the experimental platform should be adjustable to meet different experimental needs. In addition, the layout of the workbench should be reasonable, ensuring that experimental equipment and equipment are placed in an orderly manner and easy to operate. These design details should be fully considered during laboratory renovation.
3、 Design water supply and drainage systems
1. Pure water system: Many experiments have strict requirements for water quality, therefore, installing pure and ultra pure water systems is very important. The pure water system should be able to provide stable and reliable pure water to ensure the accuracy of experimental results. The ultra pure water system is used for experiments with higher requirements, such as biomedical research and high-precision analysis experiments. The design of the water supply system is an important part of laboratory renovation.
2. Wastewater treatment: Laboratory wastewater often contains harmful substances and must be treated before being discharged. Design a reasonable wastewater treatment system to ensure the effective removal of harmful substances in wastewater and avoid environmental pollution. The wastewater treatment system should include multiple processes such as neutralization, filtration, and disinfection, and wastewater treatment is an indispensable part of laboratory design.
4、 Design power system
1. Stable power supply: Laboratory equipment usually has a high demand for electricity and needs to ensure the stability of the power supply. It is recommended to install a backup power supply to cope with sudden power outages and ensure uninterrupted experiments, especially in some precision experiments where the reliability of the power system is crucial for laboratory decoration.
2. Leakage protection: To prevent electric shock accidents, laboratories should install leakage protection devices and regularly check the safety of the power system. All electrical equipment should be well grounded, and wires should have good insulation protection. The safety of the power system is very important in laboratory design.
3. Power socket layout: Reasonably arrange the position of power sockets according to equipment requirements to avoid messy wires. The sockets should be evenly distributed and have sufficient quantity to meet the usage needs of experimental equipment. A reasonable socket layout is a basic requirement for laboratory renovation.
5、 Selection of decoration materials
1. Corrosion resistant materials: Corrosion resistant materials should be used for experimental benches, floors, walls, etc., especially in chemical laboratories. The corrosion resistance of materials not only extends the service life of laboratories, but also reduces safety hazards caused by material corrosion. Material selection is crucial in laboratory decoration.
2. Anti slip flooring: Anti slip materials should be selected for laboratory flooring to reduce the risk of accidental slipping. Anti slip flooring not only improves safety, but also facilitates cleaning and maintenance. The design of the flooring is part of the laboratory renovation.
In the process of laboratory renovation, detailed design principles and precautions can ensure a safer, more efficient, and applicable environment after laboratory renovation, providing strong support for scientific research work.
