Description

Technical Field

[0001] The utility model relates to a front-end processing device of an oil fume purification system, belonging to the technical field of oil fume processing equipment. Background Art

[0002] When a restaurant is open, cooking various dishes generates a large amount of cooking fumes, which need to be promptly discharged. To protect the environment, cooking fumes must be purified before they can be discharged. Therefore, a cooking fume purification system is necessary. This system primarily purifies cooking fumes by combining two components. The first component, located at the front end of the system, draws in cooking fumes from the hood and sprays water to remove dust. The second component, located at the back end of the system, removes dust using an electrostatic field.

[0003] In practice, it is found that the existing front-end treatment device only relies on spraying water mist for treatment, which is not effective. Moreover, if used for a long time, the water consumption is large, which does not meet the requirements of sustainable development. Utility Model Content

[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0020] In the description of the present invention, it should be noted that the terms "upper", "lower", "inside", "outside", "front end", "rear end", "two ends", "one end", "the other end", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings. They are only for the convenience of describing the present invention 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. Therefore, they cannot be understood as a limitation on the present invention.

[0021] The utility model relates to a front-end processing device of an oil fume purification system, which is a processing device located at the front end of the oil fume purification system used in a restaurant.

[0022] like Figure 1 As shown, the device includes an air collecting hood 1 and a main water tank 8. The air collecting hood 1 is used to collect and gather oil smoke, and a processing chamber 2 is arranged inside the air collecting hood 1. The processing chamber 2 has an air inlet. A nozzle 3 is arranged at the air inlet of the processing chamber 2, and the nozzle 3 is connected to the upper water pipe 4, which can spray water mist to purify the smoke in the oil smoke. A cyclone separator 5 is also provided in the processing chamber 2, and the cyclone separator 5 can cause the oil smoke to generate a swirl, and realize the separation of gas and solid smoke by centrifugal action. The air outlet of the cyclone separator 5 is connected to the air duct 6, and the oil smoke that has undergone preliminary solid-gas separation enters the air duct 6 and is sent to the next processing device.

[0023] The wind collecting hood 1 has a certain length, a plurality of cyclone separators 5 are provided, and a plurality of corresponding nozzles 3 can also be provided.

[0024] A return port is located at the lower end of the treatment chamber 2. The mist sprayed by the nozzle 3 falls to the lower portion of the treatment chamber 2 and flows out through the return port. This return port is also connected to a return pipe 7, which further connects to the main water tank 8. This allows water to be returned to the main water tank 2 for recycling, improving water efficiency and conserving water. After the water in the main water tank 8 has been used for a period of time, it is drained and replaced with clean water.

[0025] Water in the main water tank 8 is supplied to the nozzle 3 via the upper water pipe 4. The main water tank 8 is connected to the upper water pipe 4. Specifically, a drain outlet 13 is provided at the lower portion of the main water tank 8. This drain outlet 13 is connected to the water inlet of the high-pressure water pump 9 via a pipe. The water outlet of the high-pressure water pump 9 is then connected to the upper water pipe 4. The high-pressure water pump 9 provides the power for the water flow and sprays the water mist through the nozzle 3.

[0026] When setting up the piping for the main water tank 8, it is further preferred to connect the water outlet of the high-pressure water pump 9 to the electric three-way valve 10 through a pipe. The electric three-way valve 10 is easy to control. One of the ports of the electric three-way valve 10 is connected to the water supply pipe 4; the other port of the electric three-way valve 10 is connected to other water-consuming parts to supply water to other water-consuming parts.

[0027] In the present invention, in a specific implementation, a heating rod and a temperature sensor are usually provided in the main water tank 8. The heating rod is used to heat the water, because hot water has a better degreasing effect. The temperature sensor is used to monitor the water temperature.

[0028] In the present invention, the main water tank 8 needs to be drained after a period of use, so a drainage pipeline is required. Accordingly, a drainage branch pipe is provided on the pipe connected to the drain port of the main water tank 8, and a drain valve 11 is connected to the outer end of the drainage branch pipe. When the sewage needs to be drained, the drain valve can be opened.

[0029] The main water tank 8 in the present invention needs to be emptied of sewage after a period of use. After the sewage is discharged, it needs to be refilled with clean water. Accordingly, a water filling port 12 needs to be provided at the upper portion of the main water tank 8. Furthermore, a solenoid valve can be provided at the water filling port 12 to control the water flow.

[0030] This utility model is a front-end treatment device for oil fume purification system. Through the cyclone separator and the water mist spraying from the nozzle, it can achieve preliminary purification of oil fume with good treatment effect. The water circulation setting of the main water tank improves the utilization rate of water and achieves the effect of water conservation.

[0031] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention.
