Description

Technical Field

[0001] This utility model relates to an oil fume treatment device, and more particularly to a shared oil fume chamber emission device. Background Technology

[0002] The diversification of business formats and the pursuit of enjoyment in consumption have guided the upgrading and transformation of commercial real estate, forming a new creation of leisure commercial clusters—commercial complexes. Commercial complexes integrate three or more functions of urban living spaces, such as urban commerce, offices, catering, hotels, and apartments, and are characterized by large building volume, complex spatial structure, and a wide variety of business formats.

[0003] A major issue for commercial complexes is the treatment and emission of cooking fumes. Under the new economic circumstances, the proportion of restaurants in commercial spaces has significantly increased, and according to leasing requirements, this proportion is generally controlled at over 30%. For example, an 80,000-square-meter commercial complex, with an average usable floor area ratio of 55% and a 35% restaurant ratio, would generate approximately 1 million cubic meters of cooking fumes. Assuming each fume extraction unit handles 30,000 to 40,000 cubic meters of airflow, this would require approximately 30 or more fume extraction devices. This would significantly restrict the rooftop landscape and outdoor spaces due to issues with fume treatment, equipment noise, and equipment placement. Currently, fume extraction equipment is typically centrally located for centralized maintenance and management. However, this requires long ductwork (commercial fume treatment generally involves high-voltage electrostatic purification to remove oil, followed by UV oxidation and decomposition to remove odors. The UV oxidation and decomposition time needs to be controlled to be over 2 seconds to achieve optimal removal; if designed for a 10-meter wind speed in the fume extraction duct, at least 20 meters of ductwork is required), resulting in scattered fume emissions and significant noise pollution. Therefore, there is an urgent need to develop an oil fume exhaust system that can effectively save pipeline installation space and reduce the noise of oil fume exhaust. Utility Model Content

[0004] The purpose of this invention is to provide a shared fume exhaust device. This invention effectively saves on piping and reduces noise from fume exhaust.

[0005] The technical solution of this utility model is as follows: a shared fume chamber emission device, including a purification unit, the purification unit being connected to an odor removal unit; the odor removal unit includes a shared fume chamber, and an odor removal device is provided inside the shared fume chamber.

[0006] In the aforementioned shared fume exhaust device, the purification unit includes a first row of fume ducts, an oil removal device, and a second row of fume ducts connected in sequence. The second row of fume ducts is connected to a third row of fume ducts via an exhaust fan, and the third row of fume ducts is connected to an odor removal unit.

[0007] In the aforementioned shared fume chamber exhaust device, the shared fume chamber includes a fume chamber body, in which an upper baffle and a lower baffle are arranged in a staggered manner. A lower exhaust chamber is provided below the lower baffle, a middle exhaust chamber is provided between the lower baffle and the upper baffle, and an upper exhaust chamber is provided above the upper baffle. A drain outlet is provided at the bottom of the lower exhaust chamber, and the side of the lower exhaust chamber is connected to a purification unit. An exhaust port is provided at the top of the upper exhaust chamber.

[0008] In the aforementioned shared fume extraction device, the drain outlet is connected to a drain pipe.

[0009] In the aforementioned shared fume exhaust device, the deodorizing device is located on the cavity wall of the lower exhaust cavity.

[0010] Compared with existing technologies, this invention, by setting up purification and deodorization units, centrally treats and discharges oil fumes, thereby effectively saving pipelines and installation space. Simultaneously, by using a shared fume chamber, oil fumes and noise are centrally controlled within a single exhaust cavity, preventing fumes from spreading and reducing noise impact. Specifically, the oil fumes are sequentially purified by the purification units and then centrally discharged into the shared fume chamber. A deodorization device installed on the inner wall of the chamber removes odors from the oil fumes. While ensuring effective oil and odor removal, it also centrally manages and discharges oil fume and noise, reducing noise levels. In summary, this invention effectively saves on pipelines and reduces noise from oil fume discharge. Attached Figure Description

Detailed Implementation

[0013] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0014] Example. A shared fume extraction device, configured as follows: Figure 1 As shown, it includes a purification unit and an odor removal unit. The purification unit includes first, second, and third exhaust ducts, an oil removal device, and an exhaust fan; the odor removal system includes an odor removal device and a shared fume chamber.

[0015] The purification unit includes first, second, and third exhaust ducts, an oil removal device E1, and an exhaust fan E2. The first exhaust duct L1 and the second exhaust duct L2 are connected via the oil removal device E1, and the second exhaust duct L2 and the third exhaust duct L3 are connected via the exhaust fan E2. The oil removal device E1 removes oil fumes from the first exhaust duct L1, and the exhaust fan E2 increases the exhaust pressure head to overcome the resistance of the exhaust system.

[0016] The shared fume chamber C1 includes upper, middle and lower exhaust chambers and upper and lower baffles.

[0017] The lower baffle B1 divides the fume chamber into a lower exhaust chamber T1 and a middle exhaust chamber T2. The lower baffle B1 serves to separate the fume chamber and also increases the length of the fume chamber, prolonging the oxidation and decomposition time of the fumes and reducing the noise along the way in the fume system.

[0018] The upper baffle B2 divides the fume chamber into a middle exhaust chamber T2 and an upper exhaust chamber T3. The upper baffle B2 serves to separate the fume chamber and also increases the length of the exhaust chamber, prolonging the oxidation and decomposition time of the fumes and reducing the noise along the way in the fume system.

[0019] The lower exhaust chamber T1 is equipped with a deodorizing device E3 to remove the odor from the fumes.

[0020] The bottom of the lower exhaust chamber T1 is provided with a drain outlet D1 and a drain pipe D2.

[0021] An exhaust port D3 is provided at the top of the upper exhaust chamber T3.

[0022] The shared fume extraction system is divided into an oil removal unit and an odor removal unit by setting up an oil removal device E1 and an odor removal device E3. The oil removal unit is connected to the oil removal device E1 and the exhaust fan E2. The oil removal device E1 removes oil particles from the fume system, and the exhaust fan E2 increases the exhaust pressure head to overcome the resistance of the exhaust system. The oil removal device E1 is connected to the first exhaust duct L1 on its left and the second exhaust duct L2 on its right. The exhaust fan E2 is connected to the second exhaust duct L2 on its left and the third exhaust duct L3 on its right. The third exhaust duct L3 is connected to the shared fume chamber C1 on its right. The shared fume chamber C1 is divided into upper, middle, and lower exhaust chambers, with the lower part being the lower exhaust chamber T1. The odor removal device E3 is installed on the wall of the lower exhaust chamber T1 to remove odors from the oil fumes. The bottom of the lower exhaust chamber T1 is equipped with a drain outlet D1 and a drain pipe D2 to remove rainwater and remaining oil fume particles that fall into the shared fume chamber C1 from the outside. Above the lower exhaust chamber T1 is the middle exhaust chamber T2, which is separated in the middle by a lower baffle B1. Above the middle exhaust chamber T2 is the upper exhaust chamber T3, which is separated in the middle by an upper baffle B2. The top of the upper exhaust chamber T3 is equipped with an exhaust vent D3. After the oil and odor are removed and the emission standards are met, the oil fumes are finally discharged into the atmosphere through the exhaust vent D3.

[0023] The control strategy of the shared fume extraction system is as follows: The fumes generated in the kitchen enter the oil removal device E1 through the first fume duct L1. After removing the oil fume particles, they enter the exhaust fan E2 through the second fume duct L2. The exhaust fan E2 raises the pressure head and enters the lower exhaust chamber T1 of the shared fume chamber C1 through the third fume duct L3. The lower exhaust chamber T1 is equipped with a deodorizing device E3. After being catalyzed by the deodorizing device E3, the fumes are oxidized and decomposed while passing through the middle exhaust chamber T2, and finally arrive at the upper exhaust chamber T3. After the fumes have been fully oxidized, decomposed and deodorized in the three exhaust chambers to meet the emission standards, they are discharged into the atmosphere through the exhaust port D3.
