酒店厨房安装油烟净化器通风排烟工程系统布置的不合理，会直接影响厨房通风排烟不顺畅，厨房通风排烟工程的系统该如何设计，才能避免这一现象呢？
济南厨房排烟厂家结合相关案例，整理了以下几点，供大家参考。
The unreasonable layout of the ventilation and smoke exhaust engineering system for installing oil fume purifiers in the hotel kitchen will directly affect the smooth ventilation and smoke exhaust in the kitchen. How can the system of the kitchen ventilation and smoke exhaust engineering be designed to avoid this phenomenon? Jinan kitchen smoke exhaust manufacturers have sorted out the following points in combination with relevant cases for your reference.
1、厨房安装油烟净化器防排烟工程中管道的水平段不宜太长。尤其安装上油烟净化器装置风阻会加大，一般水平远距离不应超过15m并且要有2%以上的坡度，水平末端设活接头，以方便清理管道内油垢。新建厨房的油烟净化器安装尽量安装在厨房近端排烟风机的前面以减少排烟管道及风机叶轮的油烟附着，延长管道清洗及风机的维护周期。接排风罩的支管应设风量调节阀。
1. The horizontal section of the pipe in the smoke control and exhaust project of the kitchen installed with the range hood purifier should not be too long. In particular, when the oil fume purifier is installed, the wind resistance will increase. Generally, the horizontal distance should not exceed 15m and there should be a slope of more than 2%. The horizontal end should be provided with a union to facilitate the cleaning of oil dirt in the pipeline. The lampblack purifier in the newly-built kitchen shall be installed in front of the smoke exhaust fan at the near end of the kitchen as far as possible to reduce the lampblack adhesion of the smoke exhaust pipe and fan impeller, and extend the pipe cleaning and fan maintenance period. The branch pipe connected to the exhaust hood shall be provided with an air volume control valve.
2、厨房送风系统应为直流方式，厨房的通风工程系统宜采用变速风机或关联又风机进行送排风。
2. The air supply system of the kitchen shall be DC, and the ventilation engineering system of the kitchen shall adopt variable-speed fans or associated fans for air supply and exhaust.
3、厨房油烟净化器装置选型应该根据厨房排风及灶头数量品配。排烟口布置厨房内送、排风口的布置应按灶具的具体位置加以考虑，不能让送风口对准厨师的头部吹风，避免影响厨师的身体健康及送风射流扰乱灶具的排风性能。
3. The selection of kitchen range hood purifier should be based on the quantity of kitchen exhaust and stove. The arrangement of smoke exhaust outlet: the arrangement of air supply and exhaust outlets in the kitchen should be considered according to the specific position of the cooker. The air supply outlet should not be directed at the chef's head to blow air, so as to avoid affecting the chef's health and disturbing the exhaust performance of the cooker by the air supply jet.
确定送风出口的出口风速时，在距地2m左右时的区域风速<0.25m>较为理想。厨房油烟净化器装置安装通风排烟工程中送风口应沿排风罩方向布置，离开罩子前方小0.7m，而排风口距排风罩越远越好。每个炒菜厨房须有岗位送风。
When determining the outlet wind speed of the air supply outlet, the regional wind speed < 0.25m > at a distance of about 2m from the ground is ideal. In the installation of kitchen lampblack purifier, the air supply outlet shall be arranged along the direction of the exhaust hood, 0.7m away from the front of the hood, and the farther the exhaust outlet is from the exhaust hood, the better. Each cooking kitchen must have post air supply.
4、机房、风机及风管的布置厨房的排风机宜设在厨房的上部，厨房为公共建筑中的一部分时，其排风机宜设在屋，这可以使风道内处于负压状态，避免气味外溢。
4. Arrangement of machine room, fan and air duct: the exhaust fan of the kitchen should be set at the upper part of the kitchen. When the kitchen is a part of a public building, the exhaust fan should be set at the roof level, which can make the air duct in a negative pressure state and avoid odor leakage.
厨房排烟风口尽量离室内空调系统通风口远点，避免厨房气味与空调系统串流，影响空调系统的空气质量。厨房的排风机一般应选用低噪音离心风机。油烟净化器装置、风机与风管链接尽量选择软连接，减少风机运行时连带管道产生噪音影响周围居民。
The smoke exhaust outlet of the kitchen shall be far away from the vent of the indoor air conditioning system as far as possible to prevent the kitchen odor from flowing with the air conditioning system and affecting the air quality of the air conditioning system. Low noise centrifugal fan shall be selected as the exhaust fan of the kitchen. Soft connection shall be selected as far as possible for the hood purifier device, the fan and the air duct, so as to reduce the noise generated by the fan and the associated pipes from affecting the surrounding residents.
必要的情况下排烟管道加装降噪处理。厨房的排风竖井好与防排烟工程的管道靠在一起以加大抽力。
If necessary, the smoke exhaust pipe shall be equipped with noise reduction treatment. The exhaust shaft of the kitchen should be close to the pipes of the smoke control project to increase the pumping force.
How to design the system of kitchen ventilation and smoke exhaust project? We explained the problem through the above four aspects. We hope it will be helpful to you. Please come to our website for more information http://www.jnqsg.com Take a look.
