  1. 油烟罩设计:
  1. Fume hood design:
  根据厨房的大小,厨房的长度为8.7米,厨房的长度为3.3米,共12米。排风罩设计成排烟与新风供应相结合,新风出口可向各个方向调节。根据厨师所在的工位,可随意调整出料口的方向和风量。房屋结构美观,价格低于分体式可拆式房屋。宽1450,厚550,起升高度1800。汽提塔罩由1.0优质不锈钢板制成,型号304/2b。为了确保即使空气吸收,防止炉灶开火或异物夯进排气罩的释放,生产安全风险,尤其是在释放的排气罩使用行错位式油阻止竞争委员会,可以随意拆卸清洗。
  According to the size of the kitchen, the length of the kitchen is 8.7 meters, the length of the kitchen is 3.3 meters, a total of 12 meters. The exhaust hood is designed to combine exhaust smoke with fresh air supply, and the outlet of fresh air can be adjusted in all directions. According to the position of the chef, the direction and air volume of the outlet can be adjusted at will. The structure of the house is beautiful and the price is lower than that of the split-type detachable house. Width 1450, thickness 550, rise 1800. The stripper cover is made of 1.0 high quality stainless steel plate, model 304/2b. In order to ensure that even if the air is absorbed, prevent the stove from firing or the release of foreign body ramming into the exhaust hood, production safety risks, especially in the exhaust hood released by the use of staggered oil to prevent the Competition Commission, can be freely disassembled and cleaned.
  2. 抽风机设计:
  2. Exhaust fan design:
  根据国家油烟排放标准及抽油烟机预计面积计算,厨房废气量及蒸汽柜内蒸汽量应达到24000 m3/h以上。考虑到风道及设备阻力损失,公司设计配置了gh-25型低噪声排风机箱。风箱参数为:流量31000m3/h,总压700Pa,电机功率11KW/380V,风机转速700r/min,噪音<72dB。由于风机运行时系统噪声较大,为降低整个排气系统的运行噪声,在风机进出口处增设了简单的消声器。
  According to the national oil fume emission standard and the predicted area of the hood, the kitchen exhaust gas and steam in the steam cabinet should reach more than 24 000 m3/h. Considering the resistance loss of air duct and equipment, the company has designed and equipped gh-25 low noise exhaust fan box. The parameters of bellows are: flow rate 31000m3/h, total pressure 700Pa, motor power 11KW/380V, fan speed 700r/min, noise < 72dB. Because of the large noise of the system when the fan is running, in order to reduce the noise of the exhaust system, a simple muffler is added at the inlet and outlet of the fan.
  3.静电油烟净化器设计:
  3. Design of electrostatic lampblack purifier:
  通过对油烟排放的计算,设计了烟道主烟道油烟净化装置,采用yy - 10p /JD滤清器+高压处理相结合的方式进行净化处理。风量可达24000 m3/h,净化率为>90%,功耗0.75KW。另一主烟道为蒸汽与油烟废气混合,可采用一套烟油净化器与yy - 8p /JD滤清器+高压处理相结合进行净化。风量可达18000 m3/h,净风量为>90%,电耗0.55KW。
  By calculating the fume emission, a fume purifying device for flue gas was designed, which was purified by yy-10p/JD filter combined with high pressure treatment. The air volume can reach 24 000 m3/h, the purification rate is over 90%, and the power consumption is 0.75 KW. The other main flue is the mixture of steam and fume exhaust gas. A set of fume purifier and yy-8p/JD filter plus high pressure treatment can be used to purify the fume. The air volume can reach 18000 m3/h, the net air volume is over 90%, and the power consumption is 0.55KW.
  4. 消防设备:
  4. Fire fighting equipment:
  为保证消防安全,公司在主风道入口处设计安装了消防阀,以避免因油烟温度过高或明火窜改风道内表面而引起火灾事故。消防阀温度控制点280℃。
  In order to ensure fire safety, the company designed and installed fire valves at the entrance of the main air duct to avoid fire accidents caused by the high temperature of oil fume or the alteration of the inner surface of the air duct by open fire. Fire valve temperature control point 280 C.

  5. 排气管道设计:
  5. Exhaust pipe design:
  根据风箱排风量计算,设计的主风道截面为780*600-600*600,风道内流量控制在17 m/s。由于流速快,主风管材质为1.0镀锌钢板,每长1.25米,30*3角钢法兰连接。该风道折X肋加强,不仅可以增加强度,还可以防止气流产生风道噪声。型材350*350-300*300出口支管,支管材质为0.75镀锌钢板,30*3角钢法兰连接。空气柜、油烟净化器室外塔采用钢架平台,主钢架采用10-8 #工字钢。所述风柜的出风口缠绕在原有楼层的室内主烟道上。设备及管路布置见设计简图。
  According to the calculation of the exhaust volume of the bellows, the cross section of the main duct is 780*600-600*600, and the flow rate in the duct is controlled at 17 m/s. Because of the fast flow rate, the main air duct is made of 1.0 galvanized steel sheet, each length of 1.25 meters, 30*3 angle steel flange connection. Strengthened X-ribs in the duct can not only increase the strength, but also prevent the airflow from generating duct noise. Profile 350*350-300*300 outlet branch pipe, branch pipe material is 0.75 galvanized steel plate, 30*3 angle steel flange connection. The outdoor tower of air cabinet and oil fume purifier adopts steel frame platform, and the main steel frame adopts 10-8_I-shaped steel. The air outlet of the air cabinet is wound in the main indoor flue of the original floor. The layout of equipment and pipeline is shown in the design sketch.
  6. 新风管道设计:
  6. Fresh air pipeline design:
  为了补充厨房配套的新鲜空气,公司设计并安装了一台sfg5-4管道轴流风机在切割配套加工间。轴流风机参数为:流量10000 m3 /h,满压200Pa,电机功率0.75kw /380V,风机转速1450r/min。由于蒸煮和烧蜡之间的管道较长,所以配备了gh-18型气箱。风箱参数为:流量12000m3/h,全压400Pa,电机功率3KW/380V,风机转速750r/min。2台风机均沿楼盖吊装,风机进、出口均安装简易消声器,主风道设计660*300,底部出风口200*200,出风口采用铝合金双层可调百叶窗。设备及管路布置见设计简图。
  In order to supplement the fresh air in kitchen, the company designed and installed a sfg5-4 pipeline axial flow fan in the cutting matching processing room. The parameters of axial flow fan are: flow rate 10000 m3/h, full pressure 200 Pa, motor power 0.75 kw/380V, fan speed 1450 r/min. Because of the long pipeline between cooking and wax burning, gh-18 gas tank is equipped. The parameters of bellows are: flow 12000m3/h, full pressure 400Pa, motor power 3KW/380V, fan speed 750r/min. Two fans are hoisted along the floor. Simple mufflers are installed at the inlet and outlet of the fans. The main duct is 660*300, the bottom outlet is 200*200, and the outlet is made of double-layer adjustable louvers made of aluminum alloy. The layout of equipment and pipeline is shown in the design sketch.
