Referring again to fig. 8, 9 and 10, fig. 8, 9 and 10 show another embodiment of the dust and oil remover with 5 layers of screens. The filter screen straight wire B2.1 is parallel to the front and rear cabinet side plates B1.3, in fact, in the embodiment of fig. 6, the filter screen a2 and the air-equalizing partition plate a10 are rotated by 90 ° to form the filter screen B2, the filter screen straight wire B2.1 is connected with the cross wire B2.2 and the air-equalizing partition plate B10, and the filter screen B2 is perpendicular to the upper cabinet side plate B1.1 or the lower cabinet side plate B1.2 and is placed at an acute angle θ with the air-equalizing partition plate B10 or the front and rear cabinet side plates B1.3.

Referring again to fig. 11 and 12, another embodiment of a de-dusting de-oiler with 5 layers of screens is shown. In fact, in the embodiment of fig. 8, the cabinet is placed horizontally, the left and right sides C1.2.1 and C1.2.2 of the lower cabinet side plate C1.2 are tilted upward, the lower part of the cabinet is in a basin shape, and a plurality of drain holes C6 are directly arranged below the lower part; when the front and the back of the filter screen are provided with liquid discharge holes and the liquid containing box C7 is sealed and sealed, 2 liquid containing boxes C7 are used separately, so that grease and dust are prevented from leaking to the back of the filter screen from the liquid discharge holes. The rest of the structure is the same as in fig. 8.
The embodiment of fig. 6-12 illustrates a dust-removing oil remover with a multi-layer filter screen structure by taking 5 layers of filter screens as an example, which is suitable for the case of large air volume or shortened case length, namely, the overlapping combination of wet dust-removing oil removers with a plurality of single-layer filter screens.
It should be noted that the terms of orientation of the upper case side plate, the lower case side plate, the front case side plate, and the rear case side plate, such as up, down, front, and rear, are used in the above embodiments as a relative position, and the position of the side plates should not be limited. In summary, the chassis includes two sets of chassis side plates disposed oppositely, one set is an upper chassis side plate and a lower chassis side plate, the other set is a front chassis side plate and a rear chassis side plate, and the two sets of side plates may be interchanged.
As mentioned above, the wet dust-removing oil remover of the utility model adopts a novel structure, as shown in the enlarged schematic diagram of figure 2, the filter screen 02 and the lower case side plate (or the air-equalizing baffle) 03 are placed at a relative inclination angle theta 02, and the filter screen straight wire 02.1 with a rectangular cross section is adopted. Under the action of a lower case side plate (or an air-equalizing partition plate), the direction of oily air flow entering from an air inlet or sprayed dusty water-containing air flow keeps a smaller acute angle theta 02 with a filter screen, the oily air flow or the sprayed dusty water-containing air flow is reduced to low-speed air flow V05 after impacting a filter screen straight wire 02.1 by high-speed air flow V04, the oily air flow or the sprayed dusty water-containing air flow is bent upwards at a large angle and then turns to flow out of a pipe by high-speed air flow V06, and grease, dust and water mist pass through a low-speed V05 air flow layer by virtue of the inertia of the high-speed air flow V04. It can be known that the higher the wind speed is, the higher the purification efficiency is, but the wind speed can not be designed to be too high, otherwise the resistance is large, or the liquid can not be dropped smoothly, or the water film on the straight wire of the filter screen can be blown off, or the noise is generated.
The utility model discloses a figure 2 design and the traditional design of figure 1 do the analysis comparison down:
the gap d01 of the blade 01 in fig. 1 and the gap d02 of the straight wire 02 of the screen in fig. 2 are preferably as small as possible, but are too small to easily block, and the same gap is preferably used here.
1. Under the same resistance, the working speed of the design chart 2 is higher than that of the traditional design chart 1, and the purification efficiency is also high; or conversely, the FIG. 2 design is much less resistive than the FIG. 1 design when operating at the same speed;
this is because the resistance of both designs is mainly the dynamic pressure loss (static pressure is converted into dynamic pressure when the wind speed is converted into high wind speed, and the energy loss is not large) when the maximum wind speed is reduced into low wind speed, so the resistance here is mainly the maximum wind speed in the device.
When the inclination angle theta 01 of the blade 01 in FIG. 1 is too small, the airflow rotation angle is too small and the efficiency is low; however, if the inclination angle is too large, the operating speed V01 increases to a speed V02 which is too high and causes a large drag. For example, if the compromise is 45 °, V02 ≈ 1.4V 01. When the drag loss is the same, i.e., V02 ═ V04, the operating speed is V04 ≈ 1.4V 01. If V01 is increased by a factor of 1.4 to achieve the same operating speed, the resistance increase for the design of FIG. 1 is 1.42I.e. 2 times, or fig. 2The resistance of the meter is less than half of the design of figure 1.
2. The quantity of the straight wires 02 of the filter screen in the figure 2 is several times larger than that of the blades 01 in the figure 1, and the purification efficiency can be much higher:
the smaller the inclination angle theta 02 in fig. 2 is, the larger the number of the straight filter screen filaments 02 is, the smaller the inclination angle theta 02 can be within 10 degrees, and the speed V05 of passing through the filter screen in fig. 2 is several times smaller than the speed V02 in fig. 1, so that the number of the straight filter screen filaments 02 in fig. 2 is several times larger than the number of the blades 01 in fig. 1 when the same air volume is treated, that is, the air flow layer distributed and treated by each straight filter screen filament is several times thinner.
3. The turning angle of the air flow after impacting the mesh can reach about 70 degrees in the design of figure 2, and the purification efficiency is higher than 45 degrees in the design of figure 1.
4. Grease and dust with low speed V01 in FIG. 1 is difficult to pass through the V02 airflow layer which is increased to 1.4 times of high speed, while grease and dust with high speed V04 in FIG. 2 easily passes through the V05 airflow layer which is decreased to several times of low speed, and the purification efficiency is higher than the design of FIG. 1.
From the above principle analysis, it can be known that in the fourth aspect of purification efficiency, the utility model of fig. 2 has a great improvement than the design of the traditional fig. 1, generally has some advantages as follows:
1. the dust and oil removing performance is better.
2. The structure is compact, the volume is small, the material consumption is less, the weight is light, and the air duct can be hung and installed.
3. It mainly loses the kinetic energy of primary air intake, so the resistance is very small, energy is saved, and the running cost is low.
4. Because the resistance is small, the dust remover can be connected in series in multiple stages to improve the dust removing efficiency, for example, the penetration rate of dust with certain particle size is K1The penetration rate of n-stage series connection is Kn＝KnE.g. first order penetration K140%, the total penetration rate after 3-stage series connection is K3＝(40％)3The total dust removal efficiency of the dust with the grain size is improved from 60 percent to 93.6 percent by 6.4 percent.
5. Can be used in combination with other dust collectors, such as: pre-treating for dedusting as the front stage of the high-efficiency electrostatic precipitator; and water mist is removed after the dust remover is sprayed.
6. The filter screen straight filament seam can achieve good dust and oil removing effect when the gap is large, and the mesh is not easy to block and does not need to be cleaned at ordinary times. If the machine case side plate needs to be cleaned, the machine case side plate can be disassembled, the high-pressure water is used for rushing the filter screen to wash or taking out the filter screen to clean, and the maintenance workload is small.
