DETAILED DESCRIPTION
[0022] The utility model is further illustrated below in combination with the drawings and specific embodiments.
[0023] As shown in Figure 1 and Figure 2 , a multiple purification fume hood electrostatic integrated machine comprises a bottom box 1 and a top box 2.
[0024] The bottom box 1 is inclined at the bottom and is provided with a first air inlet, and the top is provided with a first air outlet. Specifically, the bottom box 1 is in the shape of a right-angled triangular column, one right-angled side is used to connect with the wall, and the other right-angled side is used as the top surface, facilitating the connection of the top box 2.
[0025] The top box 2 is arranged above the bottom box 1, the bottom is provided with a second air inlet in communication with the first air outlet, and the top is provided with a second air outlet. The top box 2 is preferably in the shape of a rectangular box. The second air inlet is close to the first end of the top box 2, and the second air outlet is close to the second end of the top box 2, so that the airflow passes through the top box 2.
[0026] As shown in Figure 3 and Figure 5 , the bottom box 1 is provided with a front filter screen 3 at the first air inlet, and is provided with a support plate 4 inside, and a plurality of centrifugal oil throwing discs 5 are arranged on the support plate 4. Preferably, the front filter screen 3 is made of stainless steel, and adopts a mechanical damping collision type oil removal filter. When the stainless steel front filter screen 3 is filtering, the oil fume is under the action of the fan suction force, and is high-speedly rushed to the stainless steel front filter screen. The large-particle oil mist drops and oil dirt particles, due to their large mass and inertia, cannot change direction in time when they contact the filter screen, and directly impact the surface of the filter screen, achieving filtering separation. The centrifugal oil throwing disc 5 is arranged behind the front filter screen 3 and is made of stainless steel, and separates the oil-water mixture through centrifugal force.
[0027] The internal space of the top box 2 is divided into an air inlet chamber, a filter chamber and a fan chamber along the length direction thereof. The air inlet chamber is located above the second air inlet.
[0028] As shown in Figure 4As shown, the filter bin bottom surface is provided with a base 6, and the top surface is opposite to the base 6. The base 6 and the top surface are provided with a plurality of installation grooves 8, and the installation grooves 8 are provided with a metal primary filter screen 9, a HEPA filter screen 10, an activated carbon filter screen 11 and an electrostatic precipitator 12 in sequence from the air inlet bin to the fan bin.
[0029] The metal primary filter screen 9 is a double-layer stainless steel structure, which intercepts large oil stains. The HEPA filter screen 10 is a H12 high-efficiency material, which is used for removing PM2.5 and oil smoke fine particles. The activated carbon filter screen 11 is a modified honeycomb activated carbon layer, which adsorbs formaldehyde, benzene substances and odor molecules. The electrostatic precipitator 12 (ESP) is a high-voltage electrostatic field, which adsorbs 0.1-10 μm particulate matter.
[0030] Preferably, the top box 2 is provided with a bin opening on the filter bin side wall, and the bin opening is provided with a detachable bin door 16. The bin door 16 can facilitate replacement of the filter screens.
[0031] The fan bin is provided with a fan 13, and the second air outlet is provided on the top of the fan bin. Under the action of the fan 13, the airflow enters the bottom box 1 from the first air inlet, enters the top box 2 from the second air inlet, and finally is discharged from the second air outlet. The first air outlet is close to the first end of the bottom box 1, and the second air outlet is close to the second end of the bottom box 1, so that the airflow passes through the top box 2 along the length direction of the top box 2, so as to better contact with the filter screens.
[0032] One side of the bottom box 1 is provided with a front box 14 connected thereto, and the front box 14 is provided with a lighting lamp. At the same time, the bottom box 1 and the front box 14 are covered by a reinforcing plate 15 arranged on both sides of the bottom box 1, so as to improve the integrity and strength of the smoke hood.
[0033] The purification process of the present application is as follows: first-level physical interception: the oil fume passes through the front filter screen, the centrifugal oil throwing disc and the metal primary filter screen in sequence, to remove large particles and oil-water mixture. Second-level fine filtration: the HEPA filter screen intercepts PM2.5 and above particulate matter. Third-level chemical adsorption: the activated carbon filter screen decomposes VOCs and odor. Fourth-level electrostatic purification: the electrostatic precipitator completely adsorbs residual particles, and discharges clean air.
[0034] The airflow direction is as follows: step 1: after the oil fume enters the equipment, the front filter screen 3 intercepts large particles.
[0035] Step 2: the centrifugal oil throwing disc 5 separates the oil-water mixture, and the oil stains are collected to the bottom oil groove.
[0036] Step 3: the metal primary filter screen 9 further intercepts the oil stains, and the HEPA filter screen 10 removes PM2.5 particles.
[0037] Step 4: activated carbon filter 11 adsorbs odor and VOCs, and electrostatic precipitator 12 ionizes residual particles.
[0038] Step 5: clean air is discharged to the outside through fan 13.
[0039] The above describes preferred embodiments of the present application in detail. It should be understood that those skilled in the art can make many modifications and changes without creative labor according to the concept of the present application. Therefore, any technical solution obtained by logical analysis, reasoning or limited experiment on the basis of the existing technology according to the concept of the present application shall be within the protection scope defined by the claims.
