School canteens, shopping malls, canteens, government kitchen and other equipment fume purifier exhaust works if arranged unreasonable, it is easy to affect the kitchen exhaust smoke.
This is also one of the reasons for the outbreak of catering kitchen. What should we pay attention to when designing commercial kitchen exhaust systems?
1, the kitchen smoke fume purifier, smoke exhaust equipment on the device will increase the resistance of oil fume purifier, so the ordinary level interval should be 15cm, the slope should be above 2%.
The end of the level is provided with a live joint to facilitate cleaning up the waste in the pipeline. If the new kitchen fume purifier equipment should be as far as possible in front of the kitchen exhaust fan.
It is necessary to add fume attachment to exhaust pipe and fan impeller, extend pipeline cleaning and maintenance period of fan. The air inlet regulating valve should be installed in the branch pipe of the air exhaust hood.
2, the kitchen air supply system should be DC method. The ventilation system of the kitchen should choose a variable speed fan or a relevant fan to stop the exhaust.
3, according to the kitchen exhaust and kitchen stove quantity, choose the kitchen fume purifier. According to the detailed location of the cooker, arrange the layout of the air supply and outlet in the kitchen.
Note: in order to avoid the health of the chef and the exhaust air of the cooker, the air inlet can not be directed at the head of the chef.
4, the kitchen is part of the public building, the engine room, fans and wind pipes should be located on the roof layer. This design can make the air duct in a negative pressure shape and avoid odor spillover.
Note: in order not to affect the air quality of the air conditioning system, to avoid kitchen odor and indoor air flow, kitchen exhaust should be kept away from indoor air conditioning as far as possible.
When the fan is running, it is easy to make noise along with the pipes. In order to avoid affecting the surrounding residents, when choosing the kitchen exhaust fan, we should choose the low noise centrifugal fan, the range hood equipment,
The connection between fan and air duct should be selected by soft connection. When necessary, smoke exhaust pipes can be installed for noise reduction.
