Description

Technical Field

[0001] This utility model relates to the field of oil fume collection and sampling technology, specifically to an oil fume collection device for detecting oil fume emissions. Background Technology

[0002] Cooking fumes contain a large number of harmful substances, such as particulate matter (including PM2.5 and PM10) and volatile organic compounds (VOCs). These substances, when released into the atmosphere, lead to a decline in air quality, the formation of smog, and reduced visibility. For example, in cities, if a large number of catering businesses emit untreated or substandard cooking fumes, it will make the surrounding air polluted, harming the respiratory health of residents and the overall environmental quality of the city. Therefore, it is necessary to sample and test the emitted fumes to determine whether they meet emission standards.

[0003] Chinese Patent 202023105162.1 discloses a fume detection device, comprising a main unit housing, a fume collection bottle, and a handle. A display is mounted on one side wall of the main unit housing, an operation panel is mounted on one side of the display, a power switch is mounted on one side of the operation panel, a battery cover is mounted on the bottom of the main unit housing, a fixing buckle is mounted on one side of the battery cover, and a battery box is mounted on the top of the battery cover. The advantages are: by incorporating a rubber pad, an exhaust fan, and a second air vent, the fume sensor can be kept in a sealed environment, making the detection more accurate. Simultaneously, when ventilation is needed, removing the rubber head of the second air vent and turning on the exhaust fan of the first air vent facilitates ventilation, thereby improving the device's performance. The fume collection bottle and the main unit housing are connected by threads, making the device easy to disassemble and clean, thus extending the device's lifespan and demonstrating good practicality.

[0004] Existing oil fume emission detection devices typically have only one inlet when collecting oil fume. Only oil fume directly facing the inlet can enter the collection bottle for testing, while oil fume drifting from other directions cannot enter. Sampling from a single direction may lead to biased test data. Furthermore, when the oil fume is temporarily stored inside the collection bottle before being tested, its temperature decreases, and some components condense and adhere to the inner wall of the collection bottle, resulting in a decrease in the concentration of certain components in the collected oil fume and affecting the test results.

[0005] To address the aforementioned issues, a fume collection device for detecting oil fume emissions is proposed. Utility Model Content

[0006] The purpose of this invention is to provide an oil fume collection device for detecting oil fume emissions, which solves the problem in the prior art of inaccurate sampling due to a single sampling direction or the condensation of certain components in the oil fume when the temperature of the oil fume decreases, thus affecting the subsequent detection results.

[0007] To achieve the above objectives, the present invention provides the following technical solution: an oil fume collection device for detecting oil fume emissions, comprising a multi-directional air intake assembly, wherein the multi-directional air intake assembly comprises an air intake cylinder, one end of which is connected to a first air intake port, and the outer wall of the air intake cylinder is connected to a second air intake port, the inner wall of the air intake cylinder is fixedly connected to a guide plate, and the other end of the air intake cylinder is connected to a threaded outer ring.

[0008] Preferably, the end of the multi-directional air intake component is connected to a flue gas collection component, the flue gas collection component includes a collection cylinder inner liner, an electric heating wire is fixedly connected to the outside of the collection cylinder inner liner, and a collection cylinder outer shell is fixedly connected to the outside of the electric heating wire. A temperature control panel is installed on the outer wall of the collection cylinder outer shell, and a battery is electrically connected to the bottom of the temperature control panel. An exhaust fan is installed inside the collection cylinder inner liner, and a threaded connector is connected to one end of the collection cylinder inner liner. An exhaust port is connected to the other end of the collection cylinder inner liner, and a second threaded sealing cap is threadedly connected to the outside of the exhaust port.

[0009] Preferably, both the first air inlet and the second air inlet are funnel-shaped, and the second air inlet is arranged in a ring array relative to the outer wall of the air inlet cylinder.

[0010] Preferably, the heating wire and the exhaust fan are electrically connected to the battery, and the heating wire is spirally distributed around the outer wall of the inner liner of the collection cylinder.

[0011] Preferably, the inner liner of the collecting cylinder is made of aluminum-copper alloy, and the inner wall of the collecting cylinder is uniformly coated with an anti-stick coating, wherein the anti-stick coating is made of nano-ceramic coating.

[0012] Preferably, the outer wall of the threaded joint is threadedly connected to a multi-directional air intake assembly or a first threaded sealing cap. The multi-directional air intake assembly is used to allow oil fumes from various directions to enter the fume collection assembly through the threaded joint during collection. The first threaded sealing cap is used to seal the threaded joint after collection is completed.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. The present invention provides an oil fume collection device for detecting oil fume emissions. During sampling, multiple first air inlets and second air inlets are set up with different orientations. This allows oil fume to be collected from different angles, avoiding data deviation caused by sampling from a single direction. For complex airflow situations in the flue, multi-directional sampling can more comprehensively reflect the true state of oil fume.

[0015] 2. The present invention provides an oil fume collection device for detecting oil fume emissions. After the oil fume enters the inner liner of the collection cylinder through the multi-directional air intake component, the heating wire can be adjusted to a suitable temperature through the temperature control panel to heat the inside of the collection cylinder. This helps to prevent certain components in the oil fume collected inside from condensing upon contact with cold before being tested, effectively maintaining the original state of the oil fume at the time of sampling, thereby ensuring the accuracy of subsequent test data.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.

[0024] Example 1

[0025] Please see Figure 2 and Figure 3 This utility model discloses an oil fume collection device for detecting oil fume emissions, comprising a multi-directional air intake assembly 1. The multi-directional air intake assembly 1 includes an air intake cylinder 101, one end of which is connected to a first air intake port 102, and the outer wall of the air intake cylinder 101 is connected to a second air intake port 103. A guide plate 104 is fixedly connected to the inner wall of the air intake cylinder 101, and the other end of the air intake cylinder 101 is connected to a threaded outer ring 105. The first air intake port 102 and the second air intake port 103 are both flared, and the second air intake port 103 is arranged in a ring array about the outer wall of the air intake cylinder 101.

[0026] Please see Figure 1 and Figure 5 This utility model discloses an oil fume collection device for detecting oil fume emissions. The outer wall of the threaded joint 207 is threadedly connected to a multi-directional air intake component 1 or a first threaded sealing cap 3. The multi-directional air intake component 1 is used to allow oil fumes from various directions to enter the fume collection component 2 through the threaded joint 207 during collection. The first threaded sealing cap 3 is used to seal the threaded joint 207 after collection is completed.

[0027] During sampling, unscrew the first threaded sealing cap 3 and the second threaded sealing cap 209, and simultaneously screw the outer threaded ring 105 onto the outer wall of the threaded connector 207, connecting the multi-directional air intake assembly 1 and the flue gas collection assembly 2 together. Start the exhaust fan 206, which exhausts the gas inside the collection cylinder liner 201 through the exhaust port 208, creating a negative pressure state inside the collection cylinder liner 201. At this time, the external oily fumes will be drawn into the air intake cylinder 1 through the first air intake port 102 and the second air intake ports 103 facing different directions. Inside 01, guided by the baffle 104, the reasonable shape and position of the baffle can guide the flue gas entering from each air inlet toward the collection bottle, preventing the flue gas entering from some air inlets from flowing out from other outlets. The flue gas entering from all angles eventually faces the threaded outer ring 105 and enters the inner liner 201 of the collection cylinder through the threaded connector 207 for collection. After collection is completed, the second threaded sealing cap 209 is screwed on and the threaded outer ring 105 is unscrewed. Then, the first threaded sealing cap 3 is screwed onto the end of the threaded connector 207 for sealing.

[0028] During sampling, multiple first air inlets 102 and second air inlets 103 are set up with different orientations. This allows for the collection of oil fumes from different angles, avoiding data deviation caused by sampling from a single direction. For complex airflow conditions within the flue, multi-directional sampling can more comprehensively reflect the true state of the oil fumes.

[0029] Please see Figure 1 and Figure 4 This utility model discloses an oil fume collection device for detecting oil fume emissions. The end of the multi-directional air intake component 1 is connected to a fume collection component 2. The fume collection component 2 includes a collection cylinder inner liner 201. An electric heating wire 202 is fixedly connected to the outside of the collection cylinder inner liner 201, and a collection cylinder outer shell 203 is fixedly connected to the outside of the electric heating wire 202. A temperature control panel 204 is installed on the outer wall of the collection cylinder outer shell 203, and a storage battery 205 is electrically connected to the bottom of the temperature control panel 204. An exhaust fan 206 is installed inside the collection cylinder inner liner 201, and a threaded connector 207 is connected to one end of the collection cylinder inner liner 201. An exhaust port 208 is connected to the other end of the collection cylinder inner liner 201, and a second threaded sealing cap 209 is threadedly connected to the outside of the exhaust port 208.

[0030] Please see Figure 4 This utility model discloses an oil fume collection device for detecting oil fume emissions. The heating wire 202 and the exhaust fan 206 are electrically connected to the battery 205. The heating wire 202 is spirally distributed around the outer wall of the inner liner 201 of the collection cylinder. The inner liner 201 is made of aluminum-copper alloy. The inner wall of the inner liner 201 is uniformly coated with an anti-stick coating, and the anti-stick coating is made of nano-ceramic coating material.

[0031] After the oily exhaust gas enters the inner liner 201 of the collection cylinder through the multi-directional air intake component 1, the heating wire 202 can be adjusted to a suitable temperature through the temperature control panel 204 to heat the inside of the inner liner 201. This helps to prevent certain components in the oily exhaust gas collected inside from condensing upon contact with cold before being tested, effectively maintaining the original state of the oily exhaust gas at the time of sampling, thereby ensuring the accuracy of subsequent test data.
