Description

Technical Field

[0001] The utility model relates to the technical field of residential building oil fume treatment, in particular to an oil fume purification device for a residential building. Background Art

[0002] In recent years, the contribution of restaurant fumes to atmospheric PM2.5 has continued to increase. As the space for emission reduction from other pollution sources has been significantly narrowed, the control of fume emissions has received great attention. Fume emissions from residential buildings have become a source of pollution emissions that cannot be ignored. The purification efficiency of household range hoods is lower than that of commercial fume purifiers. Incompletely purified cooking fumes are directly discharged into the atmosphere through the flue, causing a certain impact on the air quality around the residential buildings. Although installing ordinary commercial fume purifiers on the roofs of residential buildings can achieve secondary treatment of cooking fumes and reduce emissions of pollutants such as fumes and particulate matter, the cooking time of residents is not completely unified, and the fume emission concentrations are different at different times of the day. Most ordinary commercial fume purifiers have fixed processing capacities and cannot meet the purification needs of dynamic fume emissions from residential buildings, and they also have high energy consumption.

[0011] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the utility model.

[0012] like Figure 1 As shown, in an embodiment of the utility model, a fume purification device for a residential building comprises a smoke exhaust connecting pipe 2 and a tee 5, one end of the smoke exhaust connecting pipe 2 is connected to a building chimney 1, the other end of the smoke exhaust connecting pipe 2 is connected to an unpowered exhaust fan 4, one end of the tee 5 is connected to the smoke exhaust connecting pipe 2, and the other two ports of the tee 5 are respectively connected to one end of a ventilation duct 1 6 and one end of a ventilation duct 2 7, the other end of the ventilation duct 1 6 is connected to one end of an air purification and exhaust integrated machine 12, the other end of the ventilation duct 2 7 is connected to one end of an air purification and exhaust integrated machine 2 13, the other end of the air purification and exhaust integrated machine 12 and the other end of the air purification and exhaust integrated machine 2 13 are connected to an exhaust pipe 19 through a reducer 18, the air purification and exhaust integrated machine 12 is provided with a purification section 14 and a power section 16, and the air purification and exhaust integrated machine 2 13 is provided with a purification section 2 15 and a power section 2 17.

[0014] Furthermore, a fire damper 8 is provided in the ventilation duct 1 6 , and a fire damper 10 is provided in the ventilation duct 2 7 .

[0015] Specifically, when the utility model is used, during the peak cooking period of residents, the electric valve 3 is in a closed state, the electric valve 9 and the electric valve 11 are in an open state, and the power section 16 in the purification and exhaust integrated machine 12 and the power section 17 in the purification and exhaust integrated machine 2 13 provide power.
