DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0020] In the description of the embodiments of the present application, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, which are only for the convenience of describing the embodiments of the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application. The terms "first", "second", and "third" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance. In addition, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be a connection between the two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0021] The embodiment of the present application provides a central processing station for oil fume and oil mist, such as Figure 1 and Figure 2 The oil fume and oil mist central processing station includes a plurality of start-stop controllers 12 , a pre-mechanical filter 26 , a purifier 28 , a ventilator 32 , a plurality of electric control valves 16 and a variable frequency electric control box 56 .

[0022] The multiple start-stop controllers 12 correspond to the oil fume ducts 10 of the multiple users one by one, and are electrically connected to the variable frequency electric control box 56. Specifically, the multiple start-stop controllers 12 are respectively installed near the multiple users, and the oil fume ducts 10 are located above the users. When the user uses the user to cook, the start-stop controller 12 is operated to send a start signal to the variable frequency electric control box 56; when the user finishes cooking, the start-stop controller 12 is operated to send a stop signal to the variable frequency electric control box 56. The start-stop controller 12 can be a button switch.

[0023] The inlet of the pre-mechanical filter 26 is connected to the oil fume ducts 10 of multiple users. The oil fume gas generated by the users during the cooking process enters the pre-mechanical filter 26 through the oil fume duct 10. The pre-mechanical filter 26 performs a filtering process on the oil fume gas to filter out large particles of oil in the oil fume gas.

[0024] The inlet of the purifier 28 is connected to the pre-mechanical filter 26. The gas filtered once by the pre-mechanical filter 26 enters the purifier 28, and the purifier 28 performs secondary purification on the oil fume gas, that is, it processes the tiny particles of oil and fat in the oil fume gas, so that the treated oil fume gas can meet the environmental protection requirements. Among them, the purifier 28 can be an electrostatic oil fume purifier, which can use an ionizer to ionize the gas, and the strong electric field makes the particulate matter charged to become charged particles. The charged particles collide with the collector plate and are adsorbed by the collecting electrode. In the electrostatic oil fume purifier, particles with a particle size greater than 0.1 microns are effectively collected, so that the treated oil fume becomes a gas that can meet the environmental emission requirements.

[0025] It should be noted that the purifier 28 is formed by combining one or more purification modules, and the number of the plurality of purification modules can be adjusted according to the total number of users that the oil fume and oil mist central processing station needs to serve.

[0026] The oil fume gas generated by the user is filtered by the pre-mechanical filter 26 for the first time, and then filtered by the purifier 28 for the second time. This filtering mode is multi-stage filtering. Multi-stage filtering can improve the purification and filtering efficiency of oil fume, and the pre-mechanical filter 26 performs the first filtration on the oil fume, which greatly reduces the workload of the purifier 28, thereby extending the life and maintenance cycle of the purifier 28.

[0027] The inlet of the ventilator 32 is connected to the outlet of the purifier 28. When the ventilator 32 is working, it generates power to make the gas flow, so that the oil smoke generated during the cooking process can be sucked into the purifier 28, and the oil smoke processed by the purifier 28 can be discharged into the air. Among them, the ventilator 32 can be a low-noise cabinet centrifugal ventilator.

[0028] A plurality of electric control valves 16 are installed one by one on the oil fume ducts 10 of a plurality of users, and are electrically connected to the variable frequency electric control box 56. Each electric control valve 16 can open and close the installed oil fume duct 10. When the user does not operate the start-stop controller 12, the electric control valve 16 is in a closed state. When the user operates the start-stop controller 12 to make the start-stop controller 12 send a start signal, the variable frequency electric control box 56 receives the start signal sent by the start-stop controller 12, and the variable frequency electric control box 56 controls the electric control valve 16 corresponding to the start-stop controller 12 that sends the start signal to open; when the user operates the start-stop controller 12 to make the start-stop controller 12 send a stop signal, the variable frequency control box controls the electric control valve 16 corresponding to the start-stop controller 12 that sends the stop signal to close. Among them, the electric control valve 16 can be a normally closed electric control valve.

[0029] The variable frequency electric control box 56 is electrically connected to a plurality of start-stop controllers 12, a purifier 28, a ventilator 32 and a plurality of electric control valves 16; wherein, the variable frequency electric control box 56 is configured to control the electric control valve 16 corresponding to the start-stop controller 12 that sends the start signal to be opened after the start-stop controller 12 is operated and a start signal is sent to the variable frequency electric control box 56, and to control the electric control valve 16 corresponding to the start-stop controller 12 that sends the stop signal to be closed after the start-stop controller 12 is operated and a stop signal is sent to the variable frequency electric control box 56, and to control the purifier 28 and the ventilator 32 to operate at the corresponding preset power according to the number of electric control valves 16 in the open state.

[0030] For example, Figure 1 The situation of three users is shown in the figure. The following describes the oil fume and oil mist central processing station based on the situation of three users. Three oil fume pipes 10 correspond to three users respectively, and the three oil fume pipes 10 are connected to the pre-mechanical filter 26; three electric control valves 16 are installed on the three oil fume pipes 10 respectively, and the three electric control valves 16 are electrically connected to the variable frequency electric control box 56; three start-stop controllers 12 correspond to the three users, and the three start-stop controllers 12 are connected to the variable frequency electric control box 56. Figure 1 Among the three users shown, when at least one user is cooking and operates the start-stop controller 12 so that the start-stop controller 12 sends a start signal to the variable frequency electric control box 56, the variable frequency electric control box 56 controls the electric control valve 16 corresponding to the user who is cooking to open; when at least one user has completed cooking and operates the start-stop controller 12 so that the start-stop controller 12 sends a stop signal to the variable frequency electric control box 56, the variable frequency electric control box 56 controls the electric control valve 16 corresponding to the user who has completed cooking to close. If the number of the electrically-controlled valves 16 in the open state is one, the frequency conversion electric control box 56 controls the purifier 28 and the fan 32 to operate at a first preset power; if the number of the electrically-controlled valves 16 in the open state is two, the frequency conversion electric control box 56 controls the purifier 28 and the fan 32 to operate at a second preset power; if the number of the electrically-controlled valves 16 in the open state is three, the frequency conversion electric control box 56 controls the purifier 28 and the fan 32 to operate at a third preset power; if all three electrically-controlled valves 16 are in a closed state, the frequency conversion electric control box 56 controls the purifier 28 and the fan 32 to close.

[0031] The oil fume and oil mist central treatment station can purify the oil fume of multiple users, and can selectively purify the oil fume according to the number of users actually using it. At the same time, there is no need to set up a purification device for each user, and the cost is low.

[0032] Continue to refer to Figure 1The oil fume and oil mist central processing station provided in the embodiment of the present application further includes a plurality of metering devices 14, which are respectively installed in the oil fume pipes 10 of a plurality of users in a one-to-one correspondence, and the metering devices 14 are configured to measure the oil fume flow passing through the installed oil fume pipes 10. The metering devices 14 may be gas flow meters.

[0033] The metering device 14 installed on the oil fume duct 10 can measure the oil fume flow through the oil fume duct 10 when the electric control valve 16 is in an open state, and then the fee to be charged to each user can be determined according to the metering result of the metering device 14 corresponding to each user.

[0034] For example, Figure 1 The situation of three users is shown; Figure 1 In the figure, three oil fume pipes 10 correspond to three users respectively. The oil fume and oil mist central processing station includes three metering devices 14. The three metering devices 14 are respectively installed on the three oil fume pipes 10. The metering device 14 installed on each oil fume pipe 10 is used to measure the oil fume flow of the corresponding user processed by the oil fume and oil mist central processing station.

[0035] like Figure 1 and Figure 2 As shown, the oil fume and oil mist central treatment station provided in the embodiment of the present application also includes an online monitor 66 and an online monitoring probe 38 for oil fume concentration. The online monitoring probe 38 for oil fume concentration is arranged at the outlet of the ventilator 32 and is electrically connected to the online monitor 66 for monitoring the oil fume concentration at the outlet of the ventilator 32 and transmitting the oil fume concentration data to the online monitor 66. The online monitor 66 is used to display the oil fume concentration index at the outlet of the ventilator 32 and judge whether the oil fume purification treatment meets the standard according to the oil fume concentration index.

[0036] When the oil fume concentration detected by the oil fume concentration online monitoring probe 38 is greater than the normal emission oil fume concentration, it means that the oil fume purification efficiency is reduced, and the pre-mechanical filter 26 or the plate of the purifier 28 of the oil fume mist central treatment station needs to be cleaned or replaced so as to timely maintain the purification efficiency of the oil fume mist central treatment station.

[0037] like Figure 1 and Figure 2 As shown, the oil fume and oil mist central processing station provided in the embodiment of the present application also includes a wind pressure monitoring probe 40, which is arranged at the outlet of the ventilator 32 and is electrically connected to the variable frequency electric control box 56, for monitoring the wind pressure at the outlet of the ventilator 32 and transmitting the wind pressure data to the variable frequency electric control box 56, and the variable frequency electric control box 56 is used to adjust the power of the ventilator 32 according to the wind pressure data.

[0038] The wind pressure monitoring probe 40 can determine the operating status of the oil fume and oil mist central processing station by real-time monitoring the wind pressure at the outlet of the ventilator 32. When the wind pressure data is found to be reduced, it is usually caused by two reasons. One is that the power of the ventilator 32 is too low, and the data of the wind pressure monitoring probe 40 will be transmitted to the frequency conversion control box 56. The frequency conversion control box 56 will compare the monitored wind pressure data with the preset wind pressure threshold, thereby adjusting the operating power of the ventilator 32, and then making the wind pressure at the air outlet reach a reasonable and stable range; the other is that it indicates that the oil fume discharge is blocked, and the filter or purifier 28 of the oil fume and oil mist central processing station needs to be cleaned or replaced, so that the purification efficiency of the oil fume and oil mist central processing station can be maintained in time.

[0039] like Figure 1 As shown, the oil fume and oil mist central processing station provided in the embodiment of the present application also includes a box body 18, and the pre-mechanical filter 26, the purifier 28, the ventilator 32 and the variable frequency electric control box 56 are all installed in the box body 18.

[0040] The box 18 is used to isolate the pre-mechanical filter 26, the purifier 28, the ventilator 32 and the frequency conversion electric control box 56 from the outside air to prevent the outside wind and rain from affecting the normal operation of the oil fume and oil mist central processing station. At the same time, it can block the noise and heat generated by the oil fume and oil mist central processing station during operation from propagating to the outside of the box 18, thereby reducing the impact of the oil fume and oil mist central processing station on users.

[0041] Specifically, Figure 1 As shown, the box body 18 includes an outer shell 20 and a first sound-absorbing layer 22 , and the first sound-absorbing layer 22 is disposed on the inner wall of the outer shell 20 .

[0042] like Figure 1 and Figure 2 As shown, the oil fume and oil mist central processing station provided in the embodiment of the present application also includes a heat sink 42, which is installed inside the box 18 and is electrically connected to the variable frequency electric control box 56. The heat sink 42 is configured to monitor the temperature inside the box 18 and transmit the monitored temperature data to the variable frequency electric control box 56, and when the temperature data monitored by the heat sink 42 is greater than a preset temperature threshold, the variable frequency electric control box 56 controls the heat sink 42 to cool the box 18.

[0043] The oil fume and oil mist central processing station is responsible for processing the oil fume generated by multiple users, which may cause the oil fume and oil mist central processing station to be in working state for a long time, thereby generating a large amount of heat, making the temperature inside the box 18 high, and the high temperature may cause the oil to spontaneously combust. The heat dissipation device 42 installed inside the box 18 cools the box 18 when the temperature inside the box 18 is high, so as to avoid the spontaneous combustion of oil due to high temperature.

[0044] Exemplarily, the preset temperature threshold may be 55°C.

[0045] Specifically, refer to Figure 2 The heat dissipation device 42 includes a temperature sensor 44, a heat dissipation pipe 46 and a fan 54; the temperature sensor 44 is located inside the box 18 and is electrically connected to the variable frequency electric control box 56, for monitoring the temperature inside the box 18 and transmitting temperature data to the variable frequency electric control box 56; the heat dissipation pipe 46 is at least partially located inside the box 18, and one end of the heat dissipation pipe 46 is connected to the outside of the box 18; the fan 54 is installed on the heat dissipation pipe 46 and is electrically connected to the variable frequency electric control box 56; wherein the variable frequency electric control box 56 is configured to control the fan 54 to start when the acquired temperature data is greater than a preset temperature threshold.

[0046] When the temperature inside the box 18 is greater than the preset temperature threshold, the fan 54 is controlled to start by the variable frequency electric control box 56, and the fan 54 discharges the hot air inside the box 18 out of the box 18 through the heat dissipation duct 46, and then the cold air from the outside enters the box 18, causing the temperature inside the box 18 to drop.

[0047] like Figure 2 As shown, the heat dissipation pipe 46 includes a first branch pipe 48, a second branch pipe 50 and a heat dissipation main pipe 52. The first end 52a of the heat dissipation main pipe 52 is connected to the outside of the box body 18, and the fan 54 is installed on the heat dissipation main pipe 52. The first branch pipe 48 and the second branch pipe 50 are located inside the box body 18, one end of the first branch pipe 48 and one end of the second branch pipe 50 are both connected to the second end 52b of the heat dissipation main pipe 52 relative to the first end 52a, and the other end of the first branch pipe 48 and the other end of the second branch pipe 50 extend in opposite directions perpendicular to the flow direction of the oil smoke.

[0048] When the variable frequency electric control box 56 controls the fan 54 to start, the hot air in the box body 18 enters the heat dissipation main pipe 52 from the first branch pipe 48 and the second branch pipe 50, and is discharged from the heat dissipation main pipe 52. The arrangement of the first branch pipe 48 and the second branch pipe 50 enables the hot air to flow around the purifier 28 and the ventilator 32 and then enter the first branch pipe 48 and the second branch pipe 50, so that the hot air can take away the heat on the surface of the purifier 28 and the ventilator 32 while being discharged from the box body 18, thereby achieving a better cooling effect.

[0049] like Figure 1 and Figure 2 As shown, the oil fume and oil mist central processing station provided in the embodiment of the present application further includes an exhaust pipe 34, one end of the exhaust pipe 34 is connected to the outlet of the fan 54, and the other end of the exhaust pipe 34 is located outside the box 18, and the oil fume concentration online monitoring probe 38 and the wind pressure monitoring probe 40 are both installed inside the exhaust pipe 34. The gas exhausted from the outlet of the ventilator 32 passes through the exhaust pipe 34 to the outside of the box 18.

[0050] Furthermore, the oil fume and oil mist central treatment station provided in the embodiment of the present application further includes a second silencing layer 36, which is wrapped around the outer side of the exhaust duct 34. Since the gas discharged from the outlet of the ventilator 32 has a high wind speed, resonance will occur between the gas and the exhaust duct 34, so that the exhaust duct 34 emits a large noise. The second silencing layer 36 can reduce the propagation of noise, thereby reducing the impact of the oil fume and oil mist central treatment station on surrounding residents.

[0051] like Figure 1 and Figure 2 As shown, the oil fume and oil mist central processing station provided in the embodiment of the present application further includes a rainproof cap 64, which is installed at the end of the exhaust pipe 34 located outside the box body 18. Further, the oil fume and oil mist central processing station further includes a third sound-absorbing layer arranged inside the rainproof cap 64; the gas discharged from the exhaust pipe 34 will hit the rainproof cap 64, causing the rainproof cap 64 to vibrate and emit a sound, and the third sound-absorbing layer can reduce the spread of the noise generated by the rainproof cap 64.

[0052] like Figure 1 and Figure 2 As shown, the oil fume and oil mist central processing station provided in the embodiment of the present application further includes a shock absorbing mechanism 58 , which is disposed inside the box body 18 , and the ventilator 32 is connected to the shock absorbing mechanism 58 .

[0053] Since the ventilator 32 generates vibrations when working, the shock absorbing mechanism 58 provided inside the housing 18 can slow down the transmission of the vibrations of the ventilator 32 to the housing 18 and the purifier 28, thereby reducing the generation of noise and avoiding damage to the connection between the ventilator 32 and other structures.

[0054] Specifically, the shock absorbing mechanism 58 includes a spring shock absorber 60 and a connecting hose 62; the spring shock absorber 60 is arranged at the bottom of the box body 18, and the ventilator 32 is installed on the spring shock absorber 60; the two ends of the connecting hose 62 are respectively connected to the outlet of the purifier 28 and the inlet of the ventilator 32.

[0055] The ventilator 32 generates vibrations when working, and the spring shock absorber 60 can reduce the vibrations transmitted to the box 18. The connecting hose 62 can reduce the vibrations transmitted to the purifier 28 while connecting the purifier 28 and the ventilator 32, thereby avoiding damage to the purifier 28.

[0056] The various embodiments in this specification are described in a progressive manner, and the same or similar parts between the various embodiments can be referenced to each other. Each embodiment focuses on the differences from other embodiments.

[0057] The above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit the present application. Although the present application has been described in detail with reference to the aforementioned embodiments, a person of ordinary skill in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some or all of the technical features thereof may be replaced by equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the present application.
