Shenzhen Research Laboratory Construction

Oct 18, 2018

The construction of Shenzhen scientific research laboratory, whether it is a new construction, expansion or reconstruction project, it is not simply to purchase reasonable equipment, but also to consider the overall planning, rational layout and graphic design of the laboratory, as well as power supply, water supply and supply. Infrastructure and basic conditions such as gas, ventilation, air purification, safety measures, and environmental protection. Therefore, the construction of the laboratory is a complex system engineering. In modern laboratories, advanced scientific instruments and superior and perfect laboratories are the necessary conditions for upgrading the level of modern science and technology and promoting the growth of scientific research results. “People-oriented, people and the environment” has become a topic of great concern to people. In the "safe, environmentally friendly, practical, durable, beautiful, economic, excellent, leading", the planning and design concept. The planning and design is mainly divided into six aspects: graphic design system, single structure functional design system, water supply and drainage design system, electronic control system, special gas distribution system, and harmful gas output system. The following is explained in the following six aspects.

 

Graphic design system, graphic design We mainly consider the following factors:


1, security

(1) Evacuation, evacuation, escape, smooth, unimpeded, safe passage; construction of scientific research laboratory? General laboratory doors are mainly opened inward, but if there is a room with explosion danger, the door should be opened outwards, the door The material is best to choose pressure glass.

(2) Building requirements The building of the laboratory shall be constructed of fire-resistant or non-combustible materials, and fire insulation shall be considered for partitions and ceilings. The terrazzo floor can be used, the windows should be dustproof, the indoor lighting should be good, the doors should be opened outwards, and the large laboratory should have two exits to facilitate the evacuation of personnel when accidents occur.


(3) Water supply and drainage Water supply must ensure the necessary water pressure, water quality, and water quantity to meet the needs of normal operation of the equipment. The indoor general valve should be located in a position that is easy to operate, and the sewer should be made of acid and alkali resistant materials. There should be a floor drain on the ground.


(4) Ventilation facilities Because toxic or flammable gases are often generated in laboratory work, the laboratory should have good ventilation conditions. There are generally three types of ventilation facilities:

1 Whole room ventilation With exhaust fan or ventilation shaft, the number of air changes is generally 5 times/hour.

2 Partial exhaust hood Generally installed above the hazardous gas part of large instruments. Above the harmful gases generated in the teaching laboratory, a partial exhaust hood is provided to reduce indoor air pollution.

3 Fume hood This is a local exhaust device commonly used in laboratories. There are heating sources, water sources, lighting and other fixtures. The fume hood can be made of metal materials with fireproof and explosionproof, and the anti-corrosion coating is applied inside, and the ventilation pipe should be resistant to acid and alkali gas corrosion. The fan can be installed in the top floor room and should have vibration and noise reduction. The exhaust pipe should be more than 2m above the roof. One?
