The installation of smoke exhaust in hotels is based on the number of kitchen stoves to configure the model of range hoods and the caliber of flue, and it is also determined according to the pipe size of the house.

all hotels need to be approved by the environmental protection department before opening, which is a necessary procedure, and obtaining environmental protection approval is also a prerequisite for the owner to apply for a business license. The environmental protection department requires that the hotel sewage must be discharged into the municipal sewage pipe network through the oil-water separator, and the hotel must also install an oil fume purifier that has passed the quality certification of the national environmental protection department.

according to the relevant regulations, some restaurants that are too close to residents are not allowed to engage in cooking and barbecue, but this situation needs to be analyzed in detail. Although the hotel has been approved before opening, the function of the fume purifier may be somewhat weakened after a period of time, and there is a problem of incomplete purification.
