Laboratory purification is a comprehensive project, involving civil engineering, power distribution, water supply and drainage, ventilation, lighting, safety measures, three wastes treatment and supporting installation of indoor experimental facilities. According to ED purification, in spite of all kinds of work, to build an excellent laboratory purification, we should focus on the key basic work of laboratory purification scale, environment, infrastructure, ventilation, safety and environmental protection.
1、 Design of laboratory purification cabinet
Laboratory bench and fume hood are the main equipment for laboratory purification, and the quality directly affects the experimental work and safety. Volab laboratory purification furniture is produced by advanced sheet metal flexible production line. The products are firm, acid and alkali resistant, and have heat-resistant and flame-retardant properties. Therefore, high requirements are put forward for the table top, cabinet body and support foot of the experimental platform. Compared with the wooden and stone table top in the past, the synthetic materials have a higher grade in chemical corrosion resistance, heat resistance, impact resistance and water-proof properties.
2、 Ventilation design
Most schools adopt the way of setting up independent ventilation pipe on the experimental platform. The advantage is that the harmful gas on the working platform can be quickly discharged. The disadvantage is that the whole laboratory purification environment has not been improved. Volab is to cancel the ventilation hood on the experimental platform, replace with a new type of fan, readjust the air volume and wind speed, adopt a comprehensive ventilation mode, control the diffusion of harmful gas through organized air flow movement, basically control the gas flow rate at about 0.5 m / s, and achieve 5-8 times / h of laboratory purification. As the measures of shock absorption and noise reduction have been strengthened in the project of fan installation, the noise of laboratory purification and air exchange equipment is less than 40 decibels when operating, which ensures that the air index and noise index can meet the relevant national health standards when the laboratory personnel operate.
3、 Three wastes treatment of laboratory purification
Three wastes treatment is an important problem in safety and environmental protection, especially in chemical and biological experiments, which have impact on the environment and potential safety hazards. In the process of construction and transformation of laboratory purification, we must pay full attention to it and take effective measures to prevent it.
1. Exhaust gas
The exhaust gas is usually discharged directly after dilution. For toxic and harmful gases, we try to use the physical adsorption and absorption methods in the "solid surface separation method" and "liquid phase separation method" to discharge. We choose to install activated carbon adsorption device at the end of the air outlet of the organic chemistry laboratory for pilot emission, and the effect is very good.
2, waste water
Waste acid and alkali solution shall be neutralized. After adsorption, complexation and concentration, other waste liquids, together with waste organic solvents, must be regularly submitted to the environmental protection department for fixed-point treatment.
3. Waste
It is relatively easy to collect and treat the waste generated in the experiment. Generally, it can be collected and sent to a third party for treatment.
