Description

Technical Field

[0001] This utility model relates to the technical field of kitchen fume purification equipment, specifically to a water-washable fume hood electrostatic integrated machine. Background Technology

[0002] In the field of treating oily waste gases such as catering fumes and industrial oil mist, integrated electrostatic precipitators (ESPs) have become widely used core equipment due to their combined function of oil fume collection and purification. The ESP uses a high-voltage electric field to charge particulate matter in the oily waste gas, which is then adsorbed onto the electrode plate surface, achieving efficient separation of oil mist and gas to meet stringent environmental emission requirements. However, in actual operation, existing integrated ESPs face significant maintenance challenges. Due to the complex composition of grease and particulate matter in oily waste gas, a large amount of sticky grease and particulate matter mixture quickly accumulates on the electrode plate surface after long-term operation. This fouling layer not only significantly reduces the conductivity of the electrode plate surface, causing a sharp decline in electric field strength and drastically weakening the equipment's oil fume purification capacity, but also increases the equipment's operating resistance and energy consumption. To ensure purification effectiveness, frequent manual disassembly and cleaning of the electrode plates is required, with cleaning cycles typically as short as one to two months. Frequent manual maintenance not only increases labor costs and cleaning agent consumption, but also requires machine shutdown for each cleaning operation, severely impacting the continuity of equipment use. Therefore, this utility model provides a water-washable fume hood electrostatic integrated machine. Utility Model Content

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0022] like Figure 1 and Figure 2 As shown, a multi-stage purification fume hood electrostatic integrated machine includes: a base box 1 and a top box 2.

[0023] The bottom of the base box 1 is sloping and has a first air inlet, while the top has a first air outlet. Specifically, the base box 1 is a right-angled triangular columnar structure, with one right-angled side for connection to the wall and the other right-angled side serving as the top surface for easy connection to the top box 2.

[0024] The top box 2 is positioned above the bottom box 1, with a second air inlet at the bottom communicating with the first air outlet, and a second air outlet at the top. The top box 2 is preferably a rectangular box structure. The second air inlet is located near the first end of the top box 2, and the second air outlet is located near the second end of the top box 2, allowing airflow to pass within the top box 2.

[0025] like Figure 3 As shown, the base box 1 has a pre-filter 3 at the first air inlet, and a support plate 4 inside, on which several centrifugal oil-throwing discs 5 are mounted. Preferably, the pre-filter 3 is made of stainless steel and uses mechanical damping collision-type oil removal filtration to achieve coarse filtration, filtering out large particulate impurities. The centrifugal oil-throwing discs 5 use centrifugal force to separate grease and filter it out.

[0026] The interior space of the top box 2 is divided into an air inlet chamber, a filter chamber, and a fan chamber along its length. The air inlet chamber is located above the second air inlet.

[0027] like Figure 4 As shown, an electrostatic precipitator 6 is installed inside the filter chamber, which adsorbs particles in the airflow through the action of an electrostatic field. The electrostatic precipitator 6 is existing technology, and its specific structure and principle will not be described in detail here.

[0028] A fan 7 is installed inside the fan compartment, and a second air outlet is located at the top of the fan compartment. Under the action of the fan 7, airflow enters the bottom chamber 1 through the first air inlet, then enters the top chamber 2 through the second air inlet, and finally exits through the second air outlet into the fume hood. The first air outlet is located near the first end of the bottom chamber 1, and the second air outlet is located near the second end of the bottom chamber 1, allowing airflow to pass through the top chamber 2 along its length. Preferably, the fan 7 is a low-noise fan.

[0029] A water washing module is installed on the top of the top box 2. The water washing module is directly opposite the electrostatic precipitator 6 and is used to clean the electrode plates of the electrostatic precipitator 6.

[0030] like Figure 5 As shown, the water washing module includes a water supply pipe 8 and nozzles 9. The water supply pipe 8 is fixedly installed on the top of the top chamber 2, with one end connected to the cleaning fluid source. Several nozzles 9 are connected to the bottom of the water supply pipe 8, extending into the filter chamber through openings in the top surface of the top chamber 2, and positioned above the electrode plates of the electrostatic precipitator 6. Preferably, the nozzles 9 are high-pressure rotating nozzles to ensure cleaning coverage and grease removal rate.

[0031] The water supply pipe 8 includes several parallel branch pipes, and each branch pipe is connected to several nozzles 9 evenly distributed along its length at its bottom, so that all the nozzles 9 are arranged in a matrix to ensure complete coverage of the electrostatic precipitator 6 and ensure cleaning effect.

[0032] The water supply pipe 8 is covered with a protective cover 10, which is fixed to the top of the top box 2 and serves as an isolation and protection function.

[0033] A front box 14 is connected to one side of the bottom box 1, and a light is installed inside the front box 14. At the same time, reinforcing plates 15 are provided on both sides of the bottom box 1 to cover the bottom box 1 and the front box 14, so as to improve the integrity and strength of the fume hood.

[0034] Work process:

[0035] 1. Purification stage: The oil fumes pass through the pre-filter (coarse filtration) → dynamic swirl plate (grease separation) → ESP (particulate adsorption) → low-noise fan (exhausting purified air).

[0036] 2. Cleaning stage: a. Turn off the ESP high-voltage power supply and seal the chamber to isolate and purify the airflow; b. Start the water washing module and spray alkaline cleaning solution to dissolve the grease on the electrode plates; c. The wastewater is recycled after oil-water separation, and the waste residue is discharged to the oil collection tank.

[0037] This invention decouples the purification and cleaning functions, uses a water washing module to specifically solve the maintenance problem of ESP, and combines a low-noise fan and a centrifugal oil slinger design to achieve high-efficiency purification, low energy consumption, and long-term stable technical effects, making it suitable for kitchen fume treatment in the catering industry.

[0038] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
