      kong气jing化工程应注意节neng
      Energy saving in air purification engineering
      kongdiaojing化shi一项nenghao大的工程,在设计和施工中应注意节neng措施。在设计,xi统和地区部门,song风liang计suan,温度和相对湿度的ce定,清洁shui苆iang木鲂暮蚹ong气变化,kong气比,管dao保温,风dao咬形成的泄漏lv,影xiang的主要分支连接kong气阻力的影xiang,法兰接toushi否漏气和kongdiao箱,如风shan、冷shui机等设备祅an≡駓unenghao有关,这xie细节都必xu加以kao虑。
      Air conditioning purification is a project with large energy consumption. Energy saving measures should be paid attention to in design and construction. In design, system and regional departments, air supply calculation, measurement of temperature and relative humidity, determination of cleaning level and air change, air ratio, pipeline insulation, leakage rate caused by air duct bite, influence of air resistance of main branch connection, leakage of flange joint and selection of air conditioning box, such as fan, chiller and other equipment are related to energy consumption, these details must be considered.
      这种管dao既需要经ji又需要效lv
      This kind of pipeline needs both economy and efficiency
      在集中或kongdiaojing化xi统中,对管dao的要qiushi经ji和有效的kong气gong应。前者的要qiuti现在jia格低,施工方便,运行成本高,内表面阻力小。后者shi指yan格良hao,不漏风、不song尘、不shou尘、不污染,ke防火、耐腐蚀、耐湿。
      In the centralized or air-conditioning purification system, the requirement of the pipeline is economic and effective air supply. The requirements of the former are low price, convenient construction, high operation cost and small internal surface resistance. The latter refers to strict and good, no air leakage, no dust delivery, no dust collection, no pollution, fire prevention, corrosion resistance and moisture resistance.
    kong气jing化工程
      在运行中,有时管件的局部阻力远远高yu管dao沿硉ao枇Γ枰慕9芗饕型鋞ou、yi径三通、四通等。弯tou曲lv半径应大yu矩形管dao的边长,圆形直径应为1.25倍。大截面风dao应加导叶以减shao阻力。但在实ji安装施工中,这样的chu理较shao。对yu渐缩管,不keneng突然改变管径,yi采用渐缩管。渐缩管每边的伸缩jiao应大yu15度,渐缩管每边的伸缩jiao应不大yu30度。矩形风管的三通管应沿气流弯曲管进行弯曲划分,支管也应ju有一定的曲lv半径。如果要90度jiao分开,应在肘部用一个导叶。
      In operation, sometimes the local resistance of pipe fittings is much higher than that along the pipeline, which needs to be improved. Pipe fittings mainly include elbow, reducing tee, cross, etc. The radius of curvature of the elbow Center shall be greater than the side length of the rectangular pipe, and the circular diameter shall be 1.25 times. Guide vane should be added to large section air duct to reduce resistance. But in the actual installation and construction, such treatment is less. For the reducer, it is impossible to change the pipe diameter suddenly, so the reducer should be used. The expansion angle of each side of the reducer shall be greater than 15 degrees, and the expansion angle of each side of the reducer shall not be greater than 30 degrees. The tee pipe of rectangular air duct shall be divided by bending along the air flow bending pipe, and the branch pipe shall also have a certain radius of curvature. If you want a 90 degree angle separation, use a guide vane at the elbow.
      根据气hou条件选择kongdiao机箱
      Select air conditioning cabinet according to climate conditions
      关yukongdiao箱祅an≡瘢ao虑气houhuanjing。如果在冬天气温低,kong气灰尘在北方,新的kong气预热段应该添加到襤ua愕膋ongdiao机组,和喷shuikong气chu理方式应采用使它不仅洗kong气灰尘,也使它产生热liang和温度jiao换达到所需的温度和湿度。在chao湿气hou,nan部地区的kong气粉尘浓度hen低,不需要预热新xian的kong气在冬天,kong气guo滤和温度、湿度diao整主要shi使用guo滤,冷却表面温度和湿度的diao整,也ke以加qiang温度除湿guo程,然后通guo介质guo滤效lv和终端guo滤效lv或sub-high效lv高。kongdiao箱配tao风机genghao采用变频风机,这不仅节约neng源,还nengling活diao节风liang风ya。
      As for the selection of air conditioning box, the climate environment should be considered. If the temperature is low in winter and the air dust is in the north, the new air preheating section shall be added to the general air conditioning unit, and the spray air treatment method shall be adopted to make it not only wash the air dust, but also generate heat and exchange temperature to the required temperature and humidity. In the humid climate, the air dust concentration in the south is very low, and there is no need to preheat the fresh air in winter. Air filtration and temperature and humidity adjustment mainly use filtration, cooling surface temperature and humidity adjustment, and can also strengthen the temperature dehumidification process, and then through the medium filtration efficiency and terminal filtration efficiency or sub high efficiency. It is better to use variable frequency fan for the matching fan of air conditioning box, which can not only save energy, but also flexibly adjust the air volume and pressure.
      自动控制装置,充分diao节
      Automatic control device, fully regulated
      目前,一xie制造商使用手动mo式来控制风liang簍ou鐈adiao整,但由yu控制风liang簍ou鐈a控制阀ji术层,天花板也shi彩se钢板软上xian,主要shi在安装和diao试diao整,因为,大多数mei有diao整,蔿v瞪喜籲engdiao整。为保证无砵ing礿ian的正常生产和工作,应设置一tao较为完备的自动控制装置,实现以下功neng:kong气清洁度、蝜v取a差监ce、气阀diao节;高纯气ti、纯shui、循huan冷却shui的温度、ya力、流liang检ce;气ti纯度、纯shuishui质监ce。
      At present, some manufacturers use the manual mode to control the air volume and air pressure adjustment, but because of the control of air volume and air pressure control valve technology layer, the ceiling is also the soft upper limit of color steel plate, mainly in the installation and commissioning adjustment, because most of them are not adjusted, in fact, they cannot be adjusted. In order to ensure the normal production and work of the dust-free workshop, a set of relatively complete automatic control device shall be set to realize the following functions: air cleanliness, temperature and humidity, pressure difference monitoring, air valve regulation; temperature, pressure and flow detection of high-purity gas, pure water and circulating cooling water; gas purity and pure water quality monitoring.
      kongdiaojing化xi统中的kong气滤清器随着运行时jian的增加而增大,需要diao整xi统中的kong气阀以保持风liang。xi统diao试时,为了使风机kong载启动,需要关闭风机出风口的kong气阀。风机启动后,由yu气阀ya力guo大,hennan启动风机。song风liangdiao节方便,song风ya力wen定。
      The air filter in the air-conditioning purification system increases with the increase of operation time. It is necessary to adjust the air valve in the system to maintain the air volume. During the system commissioning, in order to make the fan start without load, it is necessary to close the air valve at the air outlet of the fan. After the fan is started, it is difficult to start the fan due to the excessive pressure of the air valve. The air supply volume is easy to adjust and the air supply pressure is stable.
      这xie监ce装置ke以设计为单一xi统的celiang和控制xi统,也ke以设计为分瞛ijiang募苨uan机控制和管理xi统。当kongdiaojing化xi统关闭,无风、无超蝜v保缂尤绕鱤ui继续song电加热,造成设备损huai甚至qi火。为了避mian这种qing况,应设置无风、超温秞i绫;ぁⅫ/div>
      These monitoring devices can be designed as single system measurement and control system, or distributed computer control and management system. When the air conditioning purification system is closed, there is no wind or over temperature, the electric heater will continue to send electricity for heating, causing equipment damage or even fire. In order to avoid this kind of situation, no wind and over temperature power-off protection should be set.
      mei有电hua和火警bao警设备
      No telephone and fire alarm equipment
      无砵ing礿ian内的电hua和对讲机,ke以减shao洁jing区域内的走动人数,减shao粉尘liang,bing在发生火灾时ji时yu外jie接触,为正常工作接触创造条件。另外,要建立火灾bao警xi统,防止火灾在shi外nan以发现,造成zhong大经ji损失。
      The telephone and walkie talkie in the dust-free workshop can reduce the number of people walking in the clean area, reduce the amount of dust, and timely contact with the outside in case of fire, so as to create conditions for normal working contact. In addition, a fire alarm system should be established to prevent the fire from being difficult to be found outdoors and causing significant economic losses.
      多台冷shui机gengling活
      Multiple chillers are more flexible
      如果冷shui机需要较大的制冷liang,则不yi选择单台冷shui机。采用多机gou,采用变频diao速jiang低qi动功lv。许多机器ke以ling活使用,以mianlang费neng源。
      If the chiller needs large cooling capacity, it is not suitable to choose a single chiller. Adopt multi mechanism and frequency control to reduce starting power. Many machines can be used flexibly to avoid wasting energy.
      kongdiaoshi应在jing化shi的一侧
      The air conditioning room should be on one side of the purification room
      kongdiao房的位置应在jing化房的一侧,这样不仅ke以节约neng源,还ke以方便风dao的布置,使song风geng加合理,同时ke以节约工程成本。
      The air conditioning room shall be located on one side of the purification room, which can not only save energy, but also facilitate the arrangement of air duct, make the air supply more reasonable, and save the project cost.
