[0002] Fume is the black substance produced by the incomplete combustion of oil. The fume generated in kitchens and restaurants usually is a large number of thermal oxidation decomposition products of cooking oil and food under high-temperature conditions. During cooking, when the oil is heated and the temperature reaches the smoking point of cooking oil, which is 170 °C, the initial decomposed blue smoke appears. As the temperature continues to rise, the decomposition speed accelerates. When the temperature reaches 250 °C, a large amount of fume appears, and the fume contains a large number of carcinogens, which is harmful to human health.

[0003] An existing fume treatment system is mostly composed of components such as a flue gas collector hood, a connecting pipe, a fume purifier, and a fan. When in use:

[0004] 1. A large amount of fume particles are easily adsorbed on the inner wall of the connecting pipe in front of the fume purifier and the flue gas collector hood, and it is necessary to clean them frequently.

[0005] 2. A large amount of heat is generated during the fume generation process, and the existing fume treatment system does not reuse the heat, which is a waste of energy. Content of the Utility Model

[0006] The purpose of the utility model is to provide a fume treatment system, which has the characteristics of increasing the cleaning cycle of fume particles and reusing heat.

[0007] To achieve the above purpose, the utility model provides the following technical solution: A fume treatment system includes a flue gas collector hood. A water collecting tank is fixedly connected to the lower end of the flue gas collector hood. Two guiding mechanisms are fixedly connected inside the flue gas collector hood, which are distributed left and right and are located above the water collecting tank. The guiding mechanism includes a plurality of guiding plates that are distributed up and down and are inclined. There are gaps between the plurality of guiding plates. The lower end of the guiding plate located above is arranged outside the guiding plate located below. The lower end of the guiding plate located below extends into the interior of the water collecting tank;

[0008] A temporary storage box is fixedly connected inside the flue gas collector hood and is located above the guiding plate. Spray heads are communicated with the left and right side walls of the temporary storage box;

[0009] A heat reuse mechanism is arranged on one side of the flue gas collector hood.

[0010] In order to reuse the heat in the cooking fume, as an optimization of the cooking fume treatment system of the present utility model, the heat reuse mechanism includes a water tank arranged on the right side of the flue gas collecting hood. A heat conducting plate is fixedly connected inside the water tank, and the heat conducting plate divides the interior of the water tank into a circulation chamber and a water storage chamber;

[0011] A delivery pipe and a return pipe are respectively communicated between the circulation chamber and the temporary storage box and the water collecting tank.

[0012] In order to purify the cooking fume, as an optimization of the cooking fume treatment system of the present utility model, the upper end of the flue gas collecting hood is communicated with a cooking fume purifier through a pipe, and the right side wall of the cooking fume purifier is communicated with a fan through a pipe.

[0013] In order to pump the water in the circulation chamber into the temporary storage box through the delivery pipe, as an optimization of the cooking fume treatment system of the present utility model, one end of the delivery pipe extends to the lower end inside the circulation chamber and is provided with a water pump.

[0014] In order to filter the cooking fume particles in the water in the water collecting tank, as an optimization of the cooking fume treatment system of the present utility model, a filtering device is arranged on the outer wall of the return pipe. The filtering device includes a filtering box. A notch is formed through the upper end face of the filtering box. A fixing plate is detachably connected to the upper end face of the filtering box, and an activated carbon filtering frame extending to the lower end inside the filtering box is fixedly connected to the lower end face of the fixing plate.

[0015] In order to facilitate the injection of water into the circulation chamber and the water storage chamber, as an optimization of the cooking fume treatment system of the present utility model, two water inlet pipes respectively communicated with the circulation chamber and the water storage chamber are fixedly connected to the upper end face of the water tank.

[0016] In order to facilitate the discharge and use of the water in the water storage chamber, as an optimization of the cooking fume treatment system of the present utility model, a faucet communicated with the water storage chamber is fixedly connected to the right side wall of the water tank.

[0017] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0018] During use, the water pump pumps the water in the circulation chamber into the temporary storage box through the delivery pipe, and then sprays the water through a nozzle, so that a filtering layer is formed at the upper end inside the flue gas collecting hood;

[0019] Then, the fan is used to drive the flow of the cooking fume, so that the cooking fume passes through the filtering layer formed by the water, and the particles in the cooking fume are adsorbed by the water, thereby reducing the content of particles in the cooking fume, preventing a large amount of cooking fume particles from being adsorbed on the inner walls of the pipeline and the flue gas collecting hood, and effectively increasing the cleaning cycle of the cooking fume particles;

[0020] Meanwhile, the sprayed water flows into the water collecting tank through the flow guiding plate. Since the oil fume is in a high-temperature state, while filtering the oil fume, the water can exchange heat with the oil fume, causing the temperature of the water flowing into the water collecting tank to rise. Then, the water in the water collecting tank flows back to the circulation cavity through the return pipe, and then the heat in the water in the circulation cavity is conducted to the water storage cavity through the heat conducting plate to heat the water in the water storage cavity. The water in the water storage cavity can be used for domestic water, thus recycling the heat in the oil fume. Brief Description of the Drawings

[0028] A temporary storage box 4 located above the guiding plate 3 is fixedly connected inside the flue gas collecting hood 1. Spray heads 5 are communicated with the left and right side walls of the temporary storage box 4;

[0029] A heat reuse mechanism is arranged on one side of the flue gas collecting hood 1.

[0030] In this embodiment: During use, a water pump 14 pumps water in the circulation cavity 8 into the temporary storage box 4 through a delivery pipeline 10, and then sprays the water through the spray heads 5, so that a filter layer is formed at the upper end inside the flue gas collecting hood 1;

[0031] Then, an air blower 13 is used to suck the oil fume, so that the oil fume passes through the gaps between the plurality of guiding plates 3 and enters the flue gas collecting hood 1. The guiding plates 3 can guide the water and prevent the water from flowing out of the flue gas collecting hood 1. Then, the oil fume passes through the filter layer formed by the water, and the particles in the oil fume are adsorbed by the water, thereby reducing the content of particles in the oil fume, preventing a large amount of oil fume particles from being adsorbed on the inner walls of the pipeline and the flue gas collecting hood, effectively increasing the cleaning cycle of the oil fume particles, and then the oil fume with removed particles reaches the oil fume purifier 12 through the pipeline. The oil fume is purified by the oil fume purifier 12, and then the purified oil fume is discharged through the air blower 13;

[0034] A delivery pipeline 10 and a return pipeline 11 are respectively communicated between the circulation cavity 8 and the temporary storage box 4 and the water collecting tank 2.

[0035] In this embodiment: The ejected water flows into the water collecting tank 2 through the diversion plate 3. Since the oil fume is in a high-temperature state, while the water filters the oil fume, the water can exchange heat with the oil fume, causing the temperature of the water flowing into the water collecting tank 2 to rise. Then, the water in the water collecting tank 2 flows back into the circulation cavity 8 through the return pipe 11, and then the heat in the water in the circulation cavity 8 is conducted into the water storage cavity 9 through the heat conducting plate 7 to heat the water in the water storage cavity 9. The water in the water storage cavity 9 can be used for domestic water, thus recycling the heat in the oil fume.

[0036] As a technical optimization scheme of the present utility model, the upper end of the flue gas collecting hood 1 is connected to an oil fume purifier 12 through a pipe, and the right side wall of the oil fume purifier 12 is connected to a fan 13 through a pipe.

[0038] As a technical optimization scheme of the present utility model, one end of the conveying pipe 10 extends to the lower end inside the circulation cavity 8 and is provided with a water pump 14.

[0039] In this embodiment: The water pump 14 can pump the water in the circulation cavity 8 into the temporary storage box 4 through the conveying pipe 10.

[0040] As a technical optimization scheme of the present utility model, a filtering device 15 is provided on the outer wall of the return pipe 11. The filtering device 15 includes a filtering box 18. A notch 19 is formed through the upper end surface of the filtering box 18. The upper end surface of the filtering box 18 is detachably connected to a fixing plate 20, and the lower end surface of the fixing plate 20 is fixedly connected to an activated carbon filtering frame 21 extending to the lower end inside the filtering box 18.

[0041] In this embodiment; When the water in the water collecting tank 2 flows back into the circulation cavity 8 through the return pipe 11, the water in the water collecting tank 2 flows through the filtering box 18, causing the water in the water collecting tank 2 to pass through the activated carbon filtering frame 21, and the activated carbon filtering frame 21 filters the oil fume particles in the water in the water collecting tank 2.

[0042] As a technical optimization scheme of the present utility model, two water inlet pipes 16 respectively communicating with the circulation cavity 8 and the water storage cavity 9 are fixedly connected to the upper end surface of the water tank 6.

[0043] In this embodiment: The water inlet pipes 16 facilitate filling water into the circulation cavity 8 and the water storage cavity 9.

[0045] In this embodiment: The faucet 17 facilitates discharging the water in the water storage cavity 9 for use.

[0046] Working principle: During use, the water pump 14 pumps the water in the circulation chamber 8 into the temporary storage box 4 through the conveying pipeline 10, and then sprays the water through the nozzle 5, so that the water forms a filtering layer at the upper end inside the smoke collecting hood 1;

[0047] Then, the smoke is drawn by the fan 13, so that the smoke passes through the gaps between the plurality of flow guiding plates 3 and enters the smoke collecting hood 1. The flow guiding plates 3 can guide the water flow to prevent the water from flowing out of the smoke collecting hood 1. Then, the smoke passes through the filtering layer formed by the water, and the water adsorbs the particles in the smoke, thereby reducing the content of particles in the smoke, preventing a large amount of smoke particles from adsorbing onto the inner walls of the pipeline and the smoke collecting hood, effectively increasing the cycle of cleaning the smoke particles, and then the smoke with removed particles reaches the oil fume purifier 12 through the pipeline. The oil fume purifier 12 purifies the oil fume, and then the purified oil fume is discharged through the fan 13;

[0048] Meanwhile, the sprayed water flows into the water collecting tank 2 through the flow guiding plates 3. Since the oil fume is in a high-temperature state, when the water filters the oil fume, heat exchange can occur between the water and the oil fume, causing the temperature of the water flowing into the water collecting tank 2 to rise. Then, the water in the water collecting tank 2 flows back into the circulation chamber 8 through the return pipeline 11, and then the heat in the water in the circulation chamber 8 is conducted to the water storage chamber 9 through the heat conducting plate 7 to heat the water in the water storage chamber 9. The water in the water storage chamber 9 can be used for domestic water, thereby reusing the heat in the oil fume.
