Fresh air pre-treatment fan in the working area - provides the hotel working area (staff working position) with pretreated fresh air.
该机提供约占排油烟风量的20%排油烟风机—排去煮食区油烟罩的油气。各风管的接驳处需采取防漏风措施。为保证设备的传染效力与设备进出风口毗连的变径风管要尽量平顺。为保证设备的传染效力，必须装配长度比管径大4倍以上的直管，并采用平顺的管道来连接，所以设备轻风机的风管连接时必须采用软连接。设备运行时受到振动将不能正常任务。
This machine provides a lampblack exhaust fan that accounts for about 20% of the lampblack exhaust air volume - to exhaust the oil and gas from the lampblack hood in the cooking area. Air leakage prevention measures shall be taken at the connection of each air duct. In order to ensure the infectious effect of the equipment, the variable diameter air duct adjacent to the equipment inlet and outlet shall be as smooth as possible. In order to ensure the infectious effect of the equipment, straight pipes with a length more than 4 times the pipe diameter must be assembled and connected with smooth pipes. Therefore, flexible connection must be used when connecting the air pipes of the equipment's light fans. The equipment will not work normally if it is subject to vibration during operation.
餐饮行业的厨房油烟主要以气溶胶的形态漂浮在空气中，是城市大气中可吸入颗粒物污染的重要来源之一，济南排烟管道对大气环境及人体健康会造成极大的危害。
Kitchen lampblack in catering industry mainly floats in the air in the form of aerosol, which is one of the important sources of inhalable particulate matter pollution in urban atmosphere. Jinan smoke exhaust pipe will cause great harm to the atmospheric environment and human health.
济南厨房排烟为油烟治理提供了法律依据，使城市中餐饮业油烟污染得到了有效的控制。但在实际行动中，仍有相当一部分的油烟净化器设备由于设计不合理或管理不善，净化效率低，没有达到预想的效果。
Jinan kitchen smoke provides a legal basis for lampblack control, which effectively controls the lampblack pollution of urban Chinese food and beverage industry. However, in practice, there are still a considerable number of lampblack purifiers that have not achieved the expected effect due to unreasonable design or poor management and low purification efficiency.
防爆灯、UV灯可以经常用湿抹布擦干净，含有挡水板、运水扇、油网、过滤网等前端净化部件的和排烟罩面板一样，济南排烟管道都需要先将表面油垢铲干净，然后放在火碱水里泡，待油泥完全泡除后，再用高压水枪(清水)洗净。据经验证明，80%左右的厨房排烟不畅主要原因是油烟净化器的内置过滤网不洁堵塞。所以前端净化器的部件清洁是非常重要的。
Explosion proof lamps and UV lamps can often be wiped clean with a wet rag. Those containing water baffle, water fan, oil screen, filter screen and other front-end purification components are the same as those of the smoke exhaust hood panel. Jinan smoke exhaust pipes need to shovel the oil dirt on the surface first, and then soak in caustic water. After the oil sludge is completely soaked, they can be cleaned with a high-pressure water gun (clean water). According to experience, about 80% of kitchens have poor smoke exhaust, which is mainly caused by the dirty and blocked filter screen inside the oil smoke purifier. Therefore, it is very important to clean the components of the front-end purifier.
每家的厨房里都有烟道，同时烟道也有主副之分，主烟道贯穿整个楼体，而副烟道是相对独立的。一般家里的油烟会先到副烟道里，然后再通过隔板上的孔进入主烟道，这样可保证每户的油烟是隔离开来的。而如果将副烟道直接连接主烟道，就会由于压力过低而导致倒烟或串烟现象。
Each kitchen has a flue, and the flue can be divided into main flue and auxiliary flue. The main flue runs through the whole building, while the auxiliary flue is relatively independent. Generally, the lampblack in the home will go to the auxiliary flue first, and then enter the main flue through the hole on the partition board, so as to ensure that the lampblack in each household is isolated. If the auxiliary flue is directly connected to the main flue, the pressure will be too low, which will lead to the phenomenon of back smoke or smoke.
Jinan smoke exhaust hood focuses on the production and processing of kitchen smoke exhaust hood and other products. For more highlights, please click here: http://www.jnqsg.com , we will have more wonderful content for you to check
