[0002] The on-line oil fume monitor is installed for the purpose of environmental protection department's supervision of the oil fume emissions in the catering industry. The supervisor monitors whether the oil fume purification equipment works normally and whether the emissions exceed the standard by detecting and reporting the oil fume concentration and the equipment status in real time through this device. This device works in a highly polluted oil fume environment, so it needs to be maintained regularly to ensure that the device can work stably and reliably.

[0003] When this device works in a cooking environment with a lot of water and oil, such as the catering type of pasta, it is very easy to form condensation in the sampling pipe and the diversion pipe, resulting in water accumulation and oil accumulation. In severe cases, the "oil plug" phenomenon occurs, resulting in poor air passage, thus causing the air pump to be suffocated and damaged, and the sensor shows a low value; it will also happen that the oil and water are sucked into the internal air path and optical path of the sensor, causing the sensor to be contaminated and damaged.

[0004] Therefore, the failure rate of the on-line oil fume monitor is relatively high, causing great operation and maintenance pressure on the operation and maintenance party. Content of the Utility Model

[0005] The purpose of the utility model is to provide a filtering device and an on-line oil fume monitor to alleviate the technical problem of high failure rate of the existing on-line oil fume monitor.

[0026] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. Components of the embodiments of the present utility model usually described and illustrated in the accompanying drawings here can be arranged and designed in various different configurations.

[0027] Therefore, the following detailed description of the embodiments of the present utility model provided in the drawings is not intended to limit the scope of the present utility model claimed, but merely represents selected embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts fall within the protection scope of the present utility model.

[0028] It should be noted that: like reference numerals and letters denote like items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0029] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship in which the utility model product is usually placed during use. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present utility model. In addition, the terms "first", "second", "third", etc. are only used for descriptive distinction and cannot be understood as indicating or implying relative importance.

[0030] In addition, terms such as "horizontal" and "vertical" do not mean that the components are required to be absolutely horizontal or hanging, but can be slightly inclined. For example, "horizontal" only means that its direction is more horizontal relative to "vertical", and does not mean that the structure must be completely horizontal, but can be slightly inclined.

[0031] In the description of the present utility model, it should also be noted that unless otherwise clearly specified and defined, the terms "set", "installed", "connected", and "coupled" 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 directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0032] As Figure 1 shown, the filtering device provided by the present utility model is used to connect the collection probe and the oil fume sensor, and includes: an oil storage tank, on which an air inlet pipe 3 and an air outlet pipe 4 communicating inside and outside are provided. The outer port of the air inlet pipe 3 is connected to the collection probe, and the outer port of the air outlet pipe 4 is connected to the oil fume sensor.

[0033] The smoke collected by the collection probe enters the oil storage tank through the air inlet pipe 3. The oil and water vapor in the smoke are liquefied and fall to the bottom of the tank, and the liquefied gas enters the oil fume sensor along the air outlet pipe 4. Through the oil storage tank, the problems of water accumulation and oil accumulation in the pipeline of the oil fume online monitor can be effectively solved, and the problems of oil accumulation in the subsequent pipeline and oil ingress and damage of components can be avoided.

[0034] Along the depth direction of the oil storage tank, the inner port of the air inlet pipe 3 is lower than the inner port of the air outlet pipe 4, so as to leave more time for the smoke to liquefy, ensure that a large amount of water vapor and oil remain in the oil storage tank, and reduce the impact on the subsequent pipeline.

[0035] The orientation of the inner port of the air inlet pipe 3 and the orientation of the inner port of the air outlet pipe 4 are arranged at an angle to avoid the gas flowing out from the inner port of the air inlet pipe 3 directly flowing out from the inner port of the air outlet pipe 4. With the angle setting between the two, the gas path is bent, realizing the buffering of the air flow, increasing the time for the gas to stay in the oil storage tank, and improving the oil removal effect.

[0036] Specifically, the orientation of the inner port of the air inlet pipe 3 is consistent with the depth direction of the oil storage tank, and the orientation of the inner port of the air outlet pipe 4 is perpendicular to the orientation of the inner port of the air inlet pipe 3. The upward-in and horizontal-out air flow direction is more conducive to the accumulation of oil and water in the pipeline in the oil storage tank.

[0037] The oil storage tank includes a tank body 1 and a bottle cap 2. The tank body 1 and the bottle cap 2 are detachably connected, for example, by threaded connection. The air inlet pipe 3 and the air outlet pipe 4 are both connected to the bottle cap 2, which is convenient for users to remove the bottle tank and clean the inner cavity.

[0038] The material of the oil storage tank can be a transparent material, which is convenient for viewing the oil accumulation situation in the tank.

[0039] The filtering device further includes a liquid level detection module for detecting the liquid level in the storage oil tank. The liquid level detection module can be connected to the processor and then report the status to the supervision platform through the wireless module, timely informing the operation and maintenance personnel to arrange operation and maintenance disposal; compared with the operation and maintenance personnel through regular inspection methods, it is more efficient and accurate.

[0040] The liquid level detection module includes a capacitive liquid level sensor 6. The capacitive liquid level sensor 6 is connected to the outer wall of the storage oil tank to achieve non-contact liquid level detection, that is, the sensor does not contact the oil-water mixture, and the liquid level change can be detected. This sensor only needs to be pasted on the storage oil tank wall and will not damage the sealing of the storage oil tank.

[0041] In an implementable solution, as Figure 2 shown, a blocking net 5 is arranged in the storage oil tank. The blocking net 5 is located above the inlet port of the intake pipe 3 and below the inner port of the outlet pipe 4. The blocking net 5 contacts the upward moving smoke, increasing the contact area, and enabling more water vapor and oil to cool and liquefy.

[0042] As Figure 3 shown, the on-line fume monitor provided by the present utility model includes the above-mentioned filtering device. Since the on-line fume monitor provided by the present utility model incorporates the above-mentioned filtering device, the on-line fume monitor provided by the present utility model also has the advantages of the filtering device.

[0043] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present utility model, rather than to limit it; although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: it is still possible to modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some or all of the technical features; and 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 embodiments of the present utility model.
