[0002] During machining, an emulsion made of oil and water is used to lubricate and cool the workpiece. During machining, a large amount of flue gas containing emulsion will be generated due to high-temperature evaporation and splashing, polluting the environment. Currently, filters used in the market to treat such flue gas mainly use two types of filter elements: wire mesh media filter elements or plate electrostatic filter elements.

[0003] The filtration efficiency of wire mesh media filter is low. In order to meet the emission concentration requirements, a high-efficiency filter element is usually installed at the back end.

However, because the emulsion contains a large amount of water, after working for a period of time, the accumulated water in the filter element will cause short circuits between the metal plates, resulting in reduced filtration efficiency and even failure to continue working.

DETAILED DESCRIPTION

[0025] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0026] Combination Figure 1 , Figure 2 , Figure 3 ,as well as Figure 4 As shown together, an emulsion air purifier includes a shell 1 with two open ends. The shell 1 is preferably made of a hot-dip galvanized sheet with a thickness of 1.5 mm, and the surface is sprayed with plastic as a whole. A hanging ear 12 is also provided on the top of the shell 1. Along the gas flow direction, the inner cavity of the shell 1 is divided into a filter chamber 4 and a fan chamber 5 from bottom to top. A fan 10 is provided in the fan chamber 5, and the top of the fan chamber 5 is an air outlet 7.

[0027] The bottom end of the housing 1 is provided with a base 3, and the side of the base 3 is provided with an air inlet 6, which is connected to the filter chamber 4. The filter chamber 4 is provided with a primary filter unit and a secondary filter unit in sequence from bottom to top.

[0028] The primary filter unit includes two wire mesh filter plates arranged up and down, and the two wire mesh filter plates are preferably made of 50 mm thick stainless steel. The two wire mesh filter plates are defined as a first wire mesh filter plate 81 and a second wire mesh filter plate 82, respectively. The first wire mesh filter plate 81 is arranged in parallel with the second wire mesh filter plate 82, and the first wire mesh filter plate 81 is located below the second wire mesh filter plate 82.

[0029] Preferably, the first wire mesh filter plate 81 and the second wire mesh filter plate 82 are both arranged to be inclined relative to a horizontal plane.

[0030] Further preferably, the inclination angles of the first wire mesh filter plate 81 and the second wire mesh filter plate 82 relative to the horizontal plane are both 10°±5°.

[0031] The first wire mesh filter plate 81 and the second wire mesh filter plate 82 capture the air flow containing emulsion mist entering from the air inlet 6, and filter out oil mist or impurities larger than 5um. The captured liquid mist or impurities grow from small to large. The first wire mesh filter plate 81 is located on the second wire mesh filter plate 82 and is arranged inclined relative to the horizontal plane, so that the droplets collected by the first wire mesh filter plate 81 during the filtration process of the second wire mesh filter plate 82 slide down under the action of gravity and fall into the base for collecting oil.

[0032] The secondary filtration unit includes a micro-electrostatic filtration device. The micro-electrostatic filtration device in this embodiment is an external component, and its specific structure is not described in detail. The micro-electrostatic filtration device includes an ionization module 91 and a dust collection module 92. The ionization module 91 and the dust collection module 92 are placed horizontally up and down, and the dust collection module 92 is located above the ionization module 91. The ionization module 91 and the dust collection module 92 are both covered with plastic material to form an insulating layer, which is not easy to short-circuit.

[0033] The micro-electrostatic filtration device of this embodiment first generates a circumferential corona by discharging at the tip of the needle-shaped structure of the ionization module 91, thereby charging the particles in the airflow containing the emulsion mist, which are then adsorbed by the strong electric field force generated by the dust collecting module 92, accumulated on the high-voltage positive plate of the dust collecting module 92, and continuously aggregated to form large particles that drip into the base.

[0034] The micro electrostatic filtration device of this embodiment has an adsorption efficiency of up to 99.9% for particles below PM10, and can be directly rinsed or cleaned with water. It does not need to be replaced for a long time and has a very long service life.

[0035] In this embodiment, the micro-electrostatic module used - Intense Field Dielectric - refers to a strong electric field filter using a dielectric material as a carrier. The dielectric material forms a hollow microchannel, and the dielectric wrapped electrode sheet forms a strong electric field in the channel, which exerts a huge attraction on the charged particles moving in the air. While generating only minimal airflow impedance, it can adsorb almost 100% of the moving particles in the air, and is particularly effective in removing fine particle pollutants.

[0036] The housing 1 is also provided with an electric control box 2, which is an outsourced component, and its specific structure and working principle are not described here. The electric control box 2 is used to control the micro electrostatic filter device, and the electric control box 2 is electrically connected to the micro electrostatic filter device.

[0037] The electric control box 2 is used to control the fan 10, and the fan 10 is electrically connected to the electric control box 2. The fan 10 is preferably a DC adjustable speed fan, and the DC adjustable speed fan is equipped with a 10-speed speed regulator on the electric control box 2, and the wind speed can be adjusted on site according to the actual working conditions to match the wind speed and wind pressure that are more suitable for the working conditions on site, so that the emulsion air purifier of this embodiment can achieve a better purification effect.

[0038] The electric control box 2 of this embodiment is an outsourced component, and is provided with power supply, micro-static, fan operation indicator light, fan start and stop buttons, fan speed knob, etc., so that the emulsion air purifier of this embodiment has a very good human-machine interface. The specific structure and working principle of the electric control box 2 will not be described in detail here.

[0039] The electric control box 2 is connected to the outside of the housing 1 by using a hinge and a buckle with a self-locking function. The hinge and the buckle with a self-locking function are outsourced parts and will not be described in detail here.

[0040] Combination Figure 1 , Figure 5 , Figure 6 ,as well as Figure 7 As shown together, a joint assembly 11 for communicating with an external pipeline (not shown in the figure) is provided at the air inlet outside the base 3 .

[0041] Preferably, the joint assembly 11 includes a flange 111 connected to the base, and the flange 111 can be fixedly connected to the base 3 by bolts, and of course, it can also be fixedly connected to the base 3 by other conventional connection methods. An inner flange ring 112 and an outer flange ring 113 are arranged on the flange 111, and the length of the inner flange ring 112 is greater than the length of the outer flange ring 113, and there is a gap between the inner flange ring 112 and the outer flange ring 113, and the inner cavity of the inner flange ring 112 is connected to the air inlet 6.

[0042] Further preferably, the inner flange ring 112 extends toward the air inlet 6 to form a sealing limit portion 1121 . When in use, the sealing limit portion 1121 is inserted into the air inlet 6 .

[0043] A return port 115 is also provided on the flange 111. The return port 115 is provided in the gap between the inner flange ring 112 and the outer flange ring 113, and the opening of the return port 115 is communicated with the inner cavity of the inner flange ring 112. When in use, the return port 115 is located at the bottom of the flange 111, and the return port 115 is communicated with the inner cavity of the base 3.

[0044] The outer circumference of the inner flange ring 112 is sleeved with an air duct 114. The air duct 114 is preferably made of nylon cloth and is preferably fixedly connected to the inner flange ring 112 using a clamp 116.

[0045] After the emulsion air filter of this embodiment has been used for a long time, a small amount of overflowed airflow containing emulsion will condense into droplets, and then drip into the inner cavity of the base 3 through the reflux port 115, so as to prevent the condensate from overflowing.

[0046] The following is a detailed description of the process of using the emulsion air purifier of the utility model to purify and filter the air flow containing the emulsion:

[0047] The first wire mesh filter plate 81 and the second wire mesh filter plate 82 capture the air flow containing emulsion mist entering from the air inlet 6, and filter out oil mist or impurities larger than 5um. The captured liquid mist or impurities gather and grow from small to large. The first wire mesh filter plate 81 and the second wire mesh filter plate 82 are arranged at an angle relative to the horizontal plane, so that the droplets collected during the filtering process of the first wire mesh filter plate 81 and the second wire mesh filter plate 82 slide down under the action of gravity and fall into the base 3 for collecting oil.

[0048] The micro-electrostatic filtration device first generates a circumferential corona by discharging at the tip of the needle-shaped structure of the ionization module 91, charging the particles in the airflow containing the emulsion mist, and then adsorbing them through the strong electric field force generated by the dust collecting module 92, accumulating on the high-voltage positive plate of the dust collecting module 92, and continuously gathering to form large particles that drip into the base 3.

[0049] The micro electrostatic filtration device of this embodiment can achieve an adsorption efficiency of 99.9% for particles below PM10.
