Description

Technical Field

[0001] The present application relates to the technical field of oil fume purification, and more specifically, to a restaurant oil fume purification treatment system and a control method thereof. Background Art

[0002] The treatment of restaurant fume is an important project for urban air quality. In order to boost domestic consumption, many shopping malls have set up catering departments. However, most shopping malls are located in densely populated office or residential areas. Therefore, local environmental departments and relevant testing agencies strictly monitor the fume emission indicators of shopping malls.

[0003] In order to achieve the oil fume emission indicators, a purification system specifically for kitchen oil fumes is basically installed. At the same time, considering the convenience of maintenance, a modular oil fume purification system is often used. At present, the oil fume purification system generally includes: a dynamic interceptor, a pre-filtered air distribution network, an electric field purification module, a deep purification module and an exhaust port. Among them, the dynamic interceptor is mostly set separately above the stove, while the other parts are combined in the form of modules and set outdoors. Among them, the electric field purification module uses high-voltage static electricity to intercept oil fumes, so that the oil fume particles are loaded on the metal plate or metal cylinder that emits high-voltage static electricity. Therefore, the electric field purification module needs to be dismantled at least every two months and sent back to the factory for cleaning.

[0004] The general design of the catering fume purification system is designed for full-load use. However, according to the actual dining situation, there will be changes in dining peaks and low peaks during the day's business. Correspondingly, the catering fume purification system also has high and low peaks when treating flue gas, that is, it is impossible for the catering fume purification system to reach full load use. At present, there are generally few adjustments specifically for treating the high and low peaks of flue gas. Therefore, there is no time to treat enough fume, which occupies a large amount of usage time of each module and causes a significant reduction in the service life of each module of the system. Even if there is an adjustment method, it is currently only based on human judgment to adjust the exhaust volume periodically. Obviously, this human adjustment lacks flexibility, and the adjustment range is difficult to determine, which may affect the exhaust effect. Summary of the invention

[0005] In order to solve the problem that the existing catering oil fume purification treatment system has no adjustment for the high and low peaks of oil fume or is only roughly adjusted manually, which leads to a reduction in service life, or the rough manual adjustment has poor flexibility and poor amplitude control, which affects the smoke exhaust effect, the present application provides a catering oil fume purification treatment system and its control method.

[0034] The restaurant fume purification system and control method provided in this application have the following technical effects:

[0047] In order to solve the problem that the existing restaurant oil fume purification treatment system 100 has no adjustment for the high and low peaks of oil fume or is only roughly adjusted manually, resulting in a shortened service life, or the rough manual adjustment has poor flexibility and poor amplitude control, which affects the smoke exhaust effect, the present application provides a restaurant oil fume purification treatment system 100 and a control method thereof.

[0048] In this embodiment, the restaurant fume purification system 100 includes at least: a smoke exhaust detection device 110, an air distribution network 120, an air distribution network control device 130, an electric field purification module 140, a purification module use monitoring device 150, and an exhaust port 160. In the subsequent description of the embodiment of the present application, the corresponding front and back relationship is set according to the direction of smoke emission. In this embodiment, the smoke exhaust detection device 110 is arranged in the front area of ​​the air distribution network 120. Specifically, the front area is the area between the confluence of the flues of each stove head and the front side of the air distribution network 120. The air equalizing net 120 is installed at the air inlet 141 of the electric field purification module 140. In the present embodiment, the air equalizing net 120 covers the entire air inlet 141 of the electric field purification module 140. A plurality of through holes are evenly distributed on the air equalizing net 120. Its function is to evenly distribute the oil smoke on the front side through the air equalizing net 120 to reach each processing unit of the electric field purification module 140. In addition to ensuring the purification effect, it also helps to ensure the service life of each subsequent processing module.

[0049] In this embodiment, the electric field purification module 140 includes: at least two purification submodules 143, each of which is independently connected to the upstream and downstream modules. Figure 2 As shown, the electric field purification module 140 includes four purification submodules 143, each purification submodule 143 is installed at a different position on the mounting frame 144, and each purification submodule 143 is wrapped with a module shell along the four side walls of the flue gas discharge, that is, each purification submodule 143 is independent of each other. Each purification submodule 143 has its own air inlet 141 and air outlet 142, that is, each purification submodule 143 is independently connected to the upstream and downstream modules.

[0050] Correspondingly, the wind-balancing net 120 includes: at least two wind-balancing subnets 121. Each wind-balancing subnet 121 is installed at the air inlet 141 of the corresponding purification submodule 143. In this embodiment, the wind-balancing net 120 is connected to the wind-balancing net control device 130, which can independently switch the state of opening or closing each wind-balancing subnet 121 according to the received wind-balancing net control device 130, so that the corresponding purification submodule 143 can be freely switched between the state of use or not use, so as to achieve the purpose of flexible adjustment, and also help to improve the overall service life of the electric field purification module 140.

[0051] refer to Figure 3 In the catering fume purification system 100, the exhaust volume detection device 110 is respectively connected to the air distribution network control device 130 and the exhaust port 160, and the air distribution network control device 130 is respectively connected to the air distribution network 120 and the purification module use monitoring device 150.

[0052] The air distribution network control device 130 obtains the detection data of the exhaust volume detection device 110, generates the purification capacity corresponding to the current exhaust volume, and calculates the required number of openings of the purification submodules 143. The exhaust port 160 can adjust its rotation speed according to the detection data of the exhaust volume detection device 110.

[0053] The design basis for the purification capacity of the catering oil fume purification treatment system 100 is: generally, the exhaust volume corresponding to one stove is 2000 square meters / hour, and the purification capacity of a catering oil fume purification treatment system 100 is generally 40000-100000 square meters / hour, thereby determining the number of stoves that the corresponding catering oil fume purification treatment system 100 can handle.

[0054] Based on this design basis, a single purification submodule 143 and its upstream and downstream processing modules form an independent passage. For example, the detection data currently obtained from the smoke exhaust detection device 110 shows that the current exhaust volume is 2000 square meters / hour. Combined with the processing capacity of the restaurant fume purification treatment system 100, it can reach 40,000 square meters / hour, and the electric field purification module 140 includes 4 purification submodules 143, that is, the processing capacity corresponding to each purification submodule 143 is 10,000 square meters / hour. Therefore, it can be calculated that only 2 purification submodules 143 are currently needed for purification processing.

[0055] In addition, the wind-equalizing network control device 130 obtains the use parameters of each purification submodule 143 from the purification module use time monitoring device, and the use parameters include: the use time of the purification submodule 143, whether the corresponding wind-equalizing subnetwork 121 is equipped, the current opening and closing state parameters of the corresponding wind-equalizing subnetwork 121, etc., and confirms whether each purification submodule 143 can be used according to the use parameters. The wind-equalizing network control device 130 marks the purification submodules 143 that can be used, and according to the calculation result of the number of openings of the required purification submodules 143, sends a use confirmation message to the wind-equalizing subnetworks 121 of the corresponding number of marked purification submodules 143. The wind-equalizing subnetwork 121 forms any state control signal for adjusting the wind-equalizing subnetwork 121 to open, continue to open, close, and continue to close according to the current opening and closing state parameters, so as to control the on and off of the purification submodule 143 corresponding to the wind-equalizing subnetwork 121.

[0056] For the purification submodule 143 that cannot be used, a replacement reminder message is issued. The replaced part only occupies a part of the passage of the entire electric field purification module 140, so that the normal use of the entire catering oil fume purification treatment system 100 will not be delayed due to the replacement and maintenance operation. Moreover, it is less difficult than cleaning the entire electric field purification module 140 at one time, and the separation of a single small area of ​​the wind-distributing subnet 121 has a better effect on the uniform distribution of the smoke.

[0057] Based on the catering fume purification treatment system 100 provided by the present application, an electric field purification module 140 that was originally only a whole is divided into at least two purification submodules 143 that are independent of each other, and the wind-distributing network 120 is also divided into at least two wind-distributing submodules 121, and is installed at the air inlet 141 of the corresponding purification submodule 143, so that each purification submodule 143 is independently connected with its upstream and downstream modules to form an independent passage. And the wind-distributing network control device 130 receives the detection data of the smoke exhaust detection device 110 and the use parameters of each purification submodule 143 of the purification module use monitoring device 150, determines the purification submodule 143 that needs to be opened, and converts the state of the wind-distributing submodule 121 corresponding to the purification submodule 143 that needs to be opened to open or close. Specifically, for the purification submodule 143 that needs to be used, it is opened or kept in an open state; for the purification submodule 143 that does not need to be used, it is closed or kept in a closed state, which can improve the applicability of the smoke exhaust volume of the adjustment system.

[0058] Based on the above-mentioned embodiments, the wind-equalizing network control device 130 in the embodiments provided in the present application further includes: a baffle 131. The baffle 131 is arranged on one side of the corresponding wind-equalizing subnet 121, that is, the front side or the rear side along the emission direction of the flue gas. The size of the baffle 131 corresponds to the corresponding wind-equalizing subnet 121. Specifically, the size of the baffle 131 is consistent with the area and shape of the corresponding wind-equalizing subnet 121, or it may be smaller than the area and shape of the corresponding wind-equalizing subnet 121, but the coverage range of the baffle 131 can cover all through holes of the corresponding wind-equalizing subnet 121. In the present embodiment, the baffle 131 is movable. When the baffle 131 is closed to the corresponding wind-equalizing subnet 121, it is close to one side of the wind-equalizing subnet 121 to prevent the flue gas from entering the corresponding purification submodule 143 from the through holes of the wind-equalizing subnet 121. When the shielding plate 131 is opened to the corresponding air-distributing subnet 121, the shielding plate 131 can form a certain angle with the corresponding air-distributing subnet 121, or move to the area of ​​other air-distributing subnets 121, exposing the through holes of the air-distributing subnet 121, so that the smoke can enter the corresponding purification submodule 143. Therefore, the corresponding air-distributing subnet 121 can be opened or closed by the state change of the shielding plate 131, so as to flexibly adjust the use state of the purification submodule 143.

[0059] Furthermore, the shielding plate 131 includes at least two shielding sub-plates 1311. One shielding sub-plate 1311 corresponds to one air distribution sub-network 121. The air distribution network control device 130 obtains the detection data of the smoke exhaust volume detection device 110, and sends an opening or closing control signal to the corresponding shielding sub-plate 1311 separately. The shielding sub-plate 1311 can only switch between the opening and closing states for the corresponding air distribution sub-network 121, so that the entire system can open and close the purification sub-module 143 corresponding to each air distribution sub-network 121 more accurately.

[0060] Regarding the setting of the shielding plate 131, two more specific design solutions are provided below:

[0061] Option 1, reference Figure 4 The shielding plate 131 is located at the rear side of the wind balancing net 120, and the shielding plate 131 includes: a plurality of first shielding sub-plates 1311a. Each wind balancing sub-net 121 corresponds to a first shielding sub-plate 1311a, that is, each wind balancing sub-net 121 is equipped with a corresponding first shielding sub-plate 1311a.

[0062] In this embodiment, one end of the first shielding sub-plate 1311a is fixed to the wind-distributing sub-net 121 in a hinged manner, and the opposite end is a free end. The free end can be magnetically closed with the wind-distributing sub-net 121. The wind-distributing net control device 130 receives the detection data of the smoke exhaust volume detection device 110, and energizes the free end of the first shielding sub-plate 1311a according to the detection data to form and maintain a magnetic field. At this time, the first shielding sub-plate 1311a is in a closed state with respect to the wind-distributing sub-net 121, as shown in FIG. Figure 4 or, cancel the power supply of the free end of the first shielding sub-plate 1311a or keep it unpowered, so that the magnetic field disappears, or maintains a state without a magnetic field. At this time, the first shielding sub-plate 1311a is in an open state for the wind-averaging sub-net 121 ', such as Figure 4 The first shielding sub-plate 1311a' below.

[0063] When no magnetic field is formed, based on the effect of the flue gas, the first shielding sub-plate 1311a opens toward the corresponding purification sub-module 143, so that the flue gas can enter the purification sub-module 143. Figure 4 The first shielding sub-plate 1311a' below is in an open state with respect to the air distribution sub-net 121'. When a magnetic field is formed, under the action of the magnetic field, the first shielding sub-plate 1311a and the air distribution sub-net 121 are in a tightly closed state, preventing the flue gas from passing into the corresponding purification sub-module 143. Figure 4The upper first shielding sub-plate 1311a is in a closed state with respect to the wind-distributing sub-net 121. In this embodiment, the material of the first shielding sub-plate 1311a is metal. The material of the wind-distributing sub-net 121 can also be metal, or a magnetic material can be set at the movable closing position with the first shielding sub-plate 1311a.

[0064] Option 2, reference Figure 5 The shielding plate 131 is located at the front side of the wind equalizing network 120 . The shielding plate 131 includes: at least one second shielding sub-plate 1311b, a connecting rod 132 and at least one rotating ring 133 .

[0065] Among them, the connecting rod 132 is vertically arranged at the intersection of multiple air-equalizing sub-nets 121. In the present embodiment, the air-equalizing sub-nets 121 are on the same plane. The rotating ring 133 can be rotatably mounted on the connecting rod 132, and a second shielding sub-plate 1311b is installed on each rotating ring 133. Regardless of whether the air-equalizing sub-net 121 is opened or closed, the second shielding sub-plate 1311b is always parallel to the air-equalizing net 120. The rotating ring 133 is connected to the air-equalizing net control device 130, and receives the angle adjustment data obtained by the air-equalizing net control device 130 according to the detection data of the smoke exhaust volume detection device 110 and the use parameters of each purification sub-module 143 of the purification module use monitoring device 150, so that the respective second shielding sub-plates 1311b are turned to or moved away from the front side of the corresponding air-equalizing sub-net 121, thereby allowing smoke to pass into the corresponding purification sub-module 143, or preventing smoke from entering the purification sub-module 143. Figure 5 In the embodiment, the second shielding sub-plate 1311b is in an open state with respect to the wind-sharing sub-network 121, and the second shielding sub-plate 1311b' is in a closed state with respect to the wind-sharing sub-network 121'.

[0066] refer to Figure 6 , Figure 6 A schematic diagram of the steps of a control method for a restaurant fume purification system provided in one embodiment of the present application.

[0067] Based on the restaurant fume purification system 100 provided in all the above embodiments, a corresponding restaurant fume purification control method is provided. The steps of the method at least include:

[0068] S1, the air distribution network control device 130 obtains the detection data of the smoke exhaust volume detection device 110, and calculates the required number of the purification submodules 143 to be opened according to the detection data;

[0069] S2, the air-equalizing network control device 130 obtains the usage parameters of each of the purification submodules 143 from the purification module usage time monitoring device, determines the purification submodules 143 that can be used, determines the purification submodules 143 to be used according to the calculation result of the opening quantity, and forms the usage confirmation information; wherein, the usage parameters include: the usage time of the purification submodule 143, whether the corresponding air-equalizing subnetwork 121 is equipped, and the current opening and closing state parameters of the corresponding air-equalizing subnetwork 121;

[0070] S3. The wind-sharing network control device 130 controls the corresponding wind-sharing sub-network 121 to be in a corresponding state of opening, continuing to open, closing and continuing to close according to the use confirmation information.

[0071] Based on the control method of restaurant fume purification treatment provided by this embodiment, the use parameters of each purification submodule 143 obtained by the purification module usage time monitoring device are used to determine the purification submodule 143 that can be used, and the number of corresponding purification submodules 143 opened is obtained in combination with the real-time detection data of the smoke exhaust volume detection device 110, and the corresponding number of purification submodules 143 are selected, and the opening and closing state of the air distribution subnet 121 corresponding to the purification submodule 143 is controlled by the air distribution network control device 130. Based on the above design, the closing of the corresponding purification submodule 143 can be flexibly and accurately controlled, so that the restaurant fume purification treatment system 100 can open part of the purification submodule 143 based on the current smoke exhaust volume, and put other purification submodules 143 in a standby state, so as to improve the applicability of the smoke exhaust volume of the adjustment system, and while meeting the purification needs of the fume, it can also effectively extend the service life of the purification submodule 143, and can effectively reduce the use cost of the electric field purification module 140.

[0072] Based on the above embodiment, step S2 further includes:

[0073] The air distribution network control device 130 obtains the usage time of each purification submodule 143 from the purification module usage monitoring device 150, and compares it with the set usage time;

[0074] If the usage time is less than the set usage time, the air-equalizing network control device 130 marks the purification submodule 143;

[0075] According to the calculation result of the opening quantity, a corresponding number of marked purification submodules 143 are selected;

[0076] According to the current opening and closing state parameters of the air-balancing subnet 121, the shielding plate 131 corresponding to the selected and marked purification submodule 143 sends control information for opening or keeping the open state;

[0079] The wind-sharing network control device 130 controls the shielding sub-panel 1311 to be opened or closed according to the use confirmation information, so that the corresponding wind-sharing sub-network 121 is in a corresponding state of opening, continuing to open, closing and continuing to close.

[0080] Using the above-mentioned solution 1, the step of sending a closing control message to the shielding plate 131 corresponding to the unselected purification submodule 143 includes:

[0081] Sending a closing control message to the first shielding sub-plate 1311a corresponding to the unselected purification sub-module 143;

[0082] The wind-equalizing network control device 130 supplies power to the free end of the first shielding sub-plate 1311a, so that the free end of the first shielding sub-plate 1311a forms a magnetic field and closes with the corresponding wind-equalizing sub-network 121 under the action of the magnetic field.

[0083] Using the above-mentioned solution 2, the step of sending a closing control message to the shielding plate 131 corresponding to the unselected purification submodule 143 includes:

[0084] Sending a closing control message to the second shielding sub-plate 1311b corresponding to the purification sub-module 143 that is not in use;

[0085] The wind-equalizing network control device 130 sends corresponding angle control information to the rotating ring 133 connected to the second shielding sub-plate 1311b. The rotating ring 133 receives the angle control information and drives the connected second shielding sub-plate 1311b to rotate to the corresponding position of the wind-equalizing sub-network 121.
