Temperature reduction of steel structure factory building is a comprehensive type of problem, it must be symptomatic treatment for steel structure treatment, first of all, to find out the key elements that endanger the temperature of steel structure factory building, mainly its management methods, and then select the appropriate way purposeful... Temperature reduction of steel structure factory building is a comprehensive type of problem, steel frame structure treatment must be on it. For symptomatic treatment, the first thing is to find out the key factors that endanger the temperature of steel plant, mainly its management method, and then select the appropriate way to solve the relative primary and secondary factors purposefully, in order to exceed the excellent indoor air and the maximum cost-effective ratio. 1. Insulation and heat preservation of steel structure factory buildings can prevent large units of natural light radiation sources and heat transfer, and reduce global warming in the room.
Then, the temperature of industrial plant is greatly reduced and the natural environment of steel plant is improved. Today, there are two common ways to choose: to seal the flat roof of steel plant insulation material, usually flat roof insulation material is glass fiber cotton, common thickness of 50 m m, 75 mm, 100 mm, relative density of 10 kg/m installation can usually reduce room temperature by 5-8 C, the whole process of construction is more complex, if this old industry. For the renovation of thermal insulation and heat preservation, the original flat roof must be dismantled, the steel mesh must be pulled up, the fiberglass cotton should be paved on the steel mesh, and the original color steel roof should be covered by the steel frame structure, and then the moisture-proof solution should be done. High efficiency heat insulation and thermal insulation reflective coatings are sprayed on colored steel roofs.
This kind of commodity has excellent heat preservation and insulation function. Steel frame structure can be coated on various surface layers of metal materials, concrete, lime wall, wood structure, asbestos tile, plastic, FRP, vulcanized rubber, etc. The coating is 0.25mm thick, and its actual effect is the same as that of 10 cm-15cm glass fiber cotton. It can reflect 99.5% infrared induction, 92.5% invisible light, the maximum actual effect of sound insulation and noise reduction is 68%, and the actual effect of symmetrical sound insulation and noise reduction of steel plant is about 50%. Fire safety class A, completely non-flammable. Non-toxic safety, high efficiency and durability, service life of about 15 years (the actual recommendation can refer to the construction material file). If this method is used, the project construction can moisten the intestines and relax the bowels, without destroying the original flat roof, and can prevent the embrittlement of the flat roof.
After construction and before construction, the temperature difference between the surface layer of the slab and the room reaches 20 C, 8 - 10 C, and the energy consumption of the steel plant can be reduced by 30 - 70%. 2. The ventilation and cooling of steel plant is due to the heat and water vapor generated by some equipment in the steel plant. If the heat and water vapor are not discharged immediately, they will accumulate in the industrial plant, thereby causing the temperature rise of the steel plant to endanger the natural environment of the steel plant. The way to deal with this problem is to ensure fair ventilation in industrial buildings and install appropriate ventilation system software. Fair installation of ventilation system will obviously improve the natural gas environment of steel plant and greatly reduce the temperature of steel plant.
Installation of flat roof small elevator ventilator small elevator ventilator is based on the basic principle of gas thermal convection to carry out ventilation of this kind of ventilation equipment, when the natural environment of outdoor gas is different, it will cause gas theme activities, and then remove the organic exhaust gas and heat flow in the room. Its advantage is that it does not need additional power engineering and is more environmentally friendly. However, the natural environment is more helpful, so the forced exhaust system can not be used. The key commodities are booster ventilator, strip ventilator (lighting belt ventilation), roof ventilator and so on. The centrifugal fan driven by the forced smoke exhaust fan on flat roof is a kind of ventilation equipment driven by electric power engineering. Its exhaust system is easy to use and can be integrated into all natural environment ventilation.
Mini-elevator ventilator is a kind of ventilation equipment which relies on the basic principle of gas thermal convection. When the natural environment of outdoor gas is different, it will cause the theme activity of gas, and then remove the organic waste gas and heat flow in the room. Its advantage is that it does not need additional power engineering and is more environmentally friendly. However, the natural environment is more helpful, so the forced exhaust system can not be used. The key commodities are booster ventilator, strip ventilator (lighting belt ventilation), roof ventilator and so on. 3. Compulsory cooling of steel plant means installing industrial air-cooler on flat roof of industrial plant. Industrial air-cooler is a kind of equipment that uses the basic principle of cooling water to cool air and transmits air-cooler to room by strong exhaust fan.
It can keep the room temperature of steel plant quiet at 26-30 C. Its electricity consumption is about one-eighth of that of central air conditioning. The project cost is 1/2 of the central air-conditioning, and it is a good way to reduce the compulsory temperature of industrial plant.
