Design of system engineering exhaust system

Mar 20, 2018

Laboratory ventilation system engineering:
Design of the system engineering exhaust system: In the new or renovation project of the laboratory, participate in the planning stage to send professional engineers to the site to contact the relevant personnel according to the number of ventilation carriers in the laboratory, such as fume hood, hood, row The hood designs a complete ventilation plan. The plan includes the location of the reserved exhaust pipe wells in the building and the distribution and size of the pipes.
4. Design of gas pipeline system: According to the experimental needs of gas supply, the gas supply system design scheme is provided in conjunction with the on-site layout to precisely regulate gas pressure and flow while ensuring gas purity.
5. Environmental protection design: Provide a complete exhaust gas purification and treatment solution so that the exhaust gas generated in the experiment can be effectively solved in line with the environmental protection emission indicators.
6, product personality design: According to the experimental process and the special requirements of personnel to adjust the product structure and function to design a personalized product to meet the needs of different users.
7. Design of safety facilities: Rationally configure safety cabinets, drug cabinets and emergency items in the laboratory in accordance with international standards.

In the laboratory ventilation engineering, mechanical ventilation is generally used. Ventilation power devices, general ventilation, and local ventilation devices are mainly used, such as: fume hoods, atomic absorption hoods, and universal exhaust hoods.

Main ventilation equipment:

Fume Hoods: Fume hoods are an important safety device in the laboratory and provide an effective local ventilation method.
Use environment: Inflammable, explosive and volatile toxic and harmful gas test operation, detection of unknown performance items, qualitative and quantitative experimental operation.
The structure of the fume hoods: Three-stage bench top (top cabinet, console top, bottom cabinet); table-type fume hood walk-in/floor-standing fume hood.
Types of fume hoods: steel wood fume hoods, all-steel fume hoods, glass steel fume hoods, PP fume hoods.

Ventilation treatment system engineering:

In the daily operation process, laboratories will generate corresponding exhaust gas. If they are discharged into the atmosphere without treatment, they will inevitably cause pollution to the surrounding environment and cause damage to the human body. The inorganic exhaust gas and organic exhaust gas contained in the exhaust gas will be subject to exhaust gas. Different types of exhaust gas treatment solutions are made accordingly.

Inorganic waste:
Nitrogen oxides, sulfides, hydrogen chloride, hydrogen cyanide, sulfur dioxide and other inorganic waste gas.
A friend who purifies workshop engineering may not know what system components of the decontamination system are the main components of the (decontamination) system. Through the introduction of this article, I hope that my friends will be helpful in understanding the decontamination process. Better understanding of the purification system
The main components of the inter-depuration project are six major parts, namely: the wind pipe system, ground system, electrical system, automatic control system, water supply and drainage system, and air filtration system.

Ground system:
Epoxy resin is generally used to clean the floor. Enclosed structure system: it is simply the top, wall, and ground three parts, that is, the six surfaces that constitute the three-dimensional enclosed space. The detailed description includes doors and windows, decorative arcs, etc.;

Water supply and drainage system:
Water supply, drainage pipes, facilities and control devices;

Duct system:
Including air supply, return air, fresh air, exhaust ducts, control devices, etc.; air-conditioning systems: including cold (hot) water units (including water pumps, cooling towers, etc.) (or air-cooled pipes, etc.), piping, modular Purification of air-conditioning boxes (including mixed flow section, early efficiency section, heating section, refrigeration section, dehumidification section, pressurization section, mid-effective section, static pressure section, etc.);

Electrical System:
Lighting, power, weak current, including clean lamps, sockets, electrical cabinets, lines, monitoring, telephone and other strong and weak electricity systems;

Automatic control system:
Including temperature control, temperature control, wind pressure control, opening sequence and time control;
Air Filtration System: Other high purification filters and other purification equipment: such as ultraviolet light, ozone, transmission window, air shower (including cargo shower), clean bench, interlocking and other auxiliary cleaning equipment.
