[0002] In the catering industry, oil fume emissions are an important environmental issue as well as a health and safety issue. In order to maintain environmental hygiene and protect the health of employees and customers, the catering industry usually needs to strictly control oil fume emissions. Oil fume emissions are usually strictly controlled and regulated by local environmental protection laws and regulations. In order to comply with regulatory requirements, the catering industry usually needs to install oil fume purification equipment.

[0003] For example, the utility model patent with announcement number CN217274380U discloses an emission device for detecting oil fume concentration in a restaurant, including a smoke guide frame, a conduction mechanism, a first purification mechanism, a detection mechanism, an adjustment mechanism, a second purification mechanism and a fan mechanism. The conduction mechanism is arranged on the top of the smoke guide frame. The utility model arranges an adjustment frame, a rotating frame, a connecting groove and a motor.

The oil fume purifier is suitable for various kitchens, including home kitchens and commercial kitchens. The oil fume purifier 6 is an existing structure that can be directly purchased on the market, and no further elaboration will be made here.

[0026] refer to Figure 1 , Figure 2 An exhaust passage 11 is fixedly installed on the right side of the oil fume purifier 6, and a connecting plate 2 12 is fixedly installed on one side of the exhaust passage 11 by means of a set bolt 3, and a flexible connection 2 13 is fixedly installed on one side of the connecting plate 2 12, and a fixing plate 14 is fixedly installed on one end of the flexible connection 2 13 away from the connecting plate 2 12, and a U-shaped conduit 15 is fixedly installed on one side of the fixing plate 14 by means of a set bolt 4, and an exhaust pipe 16 is fixedly installed on one side of the U-shaped conduit 15; through the set connecting plate 2 12 and the fixing plate 14, it is convenient to install the U-shaped conduit 15, so that the filtered and purified gas is discharged into the interior of the exhaust pipe 16 through the exhaust passage 11 and the U-shaped conduit 15, and one end of the exhaust pipe 16 is fixed to one side of the fan box, so that the operation of the fan inside the fan box drives the gas circulation, so that the smoke in the kitchen can be filtered, purified and discharged quickly.

[0027] refer to Figure 1 A fume sensor 25 is fixedly installed on the top surface of the exhaust pipe 16, and the detection end of the fume sensor 25 extends to the inside of the exhaust pipe 16; the fume sensor 25 is set to facilitate the detection of the filtered and purified flue gas. The fume sensor 25 is used to detect the fume concentration inside the exhaust pipe 16. It can sense the fume particles in the air and convert them into electrical signals. The fume sensor 25 can be connected to the terminal alarm. When the fume sensor 25 detects that the exhaust fume concentration exceeds the set value, it will feedback an electrical signal, so that the external alarm will sound an alarm, which is convenient for personnel to respond and deal with it in time.

[0028] refer to Figure 1A gas flow sensor 26 is fixedly installed on the side of the exhaust pipe 16, and the detection end of the gas flow sensor 26 extends to the inside of the exhaust pipe 16; the gas flow sensor 26 is used to detect the speed of the gas flow inside the exhaust pipe 16. For example, when the smoke is discharged through the smoke guide pipe 4 on the top of the regulating box 3 and the oil fume purifier 16, the smoke flow rate is detected by the set gas flow sensor 26. The gas flow sensor 26 does not react within the normal range. When the gas flow sensor 26 detects that the smoke flow rate inside the exhaust pipe 16 decreases and exceeds the lower limit of the set value, it is approximately It can be determined that the filter and other components inside the fume purifier 6 are blocked, which hinders the circulation of gas. At this time, the gas flow sensor 26 feeds back a signal to the terminal controller, and the controller controls the electric push rod 21 to start. The electric push rod 21 drives the sealing baffle 21 to move upward to block and seal the smoke duct 4 on the top of the top adjustment box 3. At this time, the smoke flows through the smoke duct 4 at the bottom of the adjustment box 3, so that the smoke in the kitchen can be continuously discharged, which is convenient for personnel to work. When the personnel are free, the smoke duct 4 on the top of the adjustment box 3 and the fume purifier 6 can be inspected and maintained separately to improve convenience.

[0029] The implementation principle of the embodiment of the restaurant oil fume detection and emission equipment of the present application is as follows: the user first starts the fan installed at one end of the exhaust pipe 16. When the fan is running, the smoke inside the kitchen enters the interior of the oil fume purifier 6 through the smoke hood 1, the connecting pipe 2, the regulating box 3 and the smoke guide pipe 4 for filtering and purification. The smoke after filtering and purification will be discharged through the U-shaped duct 15 and the exhaust pipe 16. When the smoke is discharged, the concentration in the smoke will be detected by the oil fume sensor 25. The oil fume sensor 25 can be connected to the terminal alarm. When the oil fume sensor 25 detects that the concentration of the discharged smoke exceeds the set value, it will feedback an electrical signal. The external alarm sounds an alarm, which makes it easy for personnel to respond and handle it in time. When the oil fume purifier 6 needs to be disassembled and cleaned after long-term use, the personnel will unscrew the bolts on the mounting plate 10 and the fixing plate 14, so that it is convenient to fold and store the flexible connection 1 9 and the flexible connection 2 13, so that it is convenient for personnel to disassemble and remove the oil fume purifier 6 to replace or clean the filter, electrostatic dust collector and activated carbon filter layer inside it. The device has a simple structure and is easy to operate. The oil fume purifier 6 is easy to disassemble and install, making it more convenient for personnel to maintain and clean the oil fume purifier 6, thereby improving convenience.

[0030] By setting up the gas flow sensor 26, it is convenient to detect the gas flow rate discharged from the exhaust pipe 16. When the gas flow sensor 26 detects that the flue gas flow rate inside the exhaust pipe 16 decreases and exceeds the lower limit of the set value, it can be roughly determined that the filter and other components inside the fume purifier 6 are blocked and hinder the flow of gas. At this time, the gas flow sensor 26 feeds back a signal to the terminal controller, and the controller controls the electric push rod 21 to start. The electric push rod 21 drives the sealing baffle 21 to move upward to block and seal the smoke guide pipe 4 on the top of the top adjustment box 3. At this time, the smoke entering the adjustment box 3 will flow and be discharged through the smoke guide pipe 4 at the bottom. In this way, the smoke in the kitchen can be continuously discharged, which is convenient for personnel to work. When the personnel are free, the smoke guide pipe 4 on the top of the adjustment box 3 and the fume purifier 6 can be inspected and maintained separately, so that the work of the kitchen personnel will not be interrupted.
