Description

Dust removal equipment

This creation is about a kind of dust removal equipment, especially one that can filter out pollutants in stages and adsorb fine dust by static electricity.

According to the general processing plant, in the process of manufacturing, more or less will generate exhaust gas, dust, and exhaust gas dust contains gas and particulate pollutants harmful to the human body and the environment, in order to maintain air quality and ensure the health of the human body, Exhaust gas and dust containing contaminants must be treated to reduce the concentration to a safe standard before discharge; for example, in the paint factory, generally, in the painting and painting work, the paint that is not attached to the painted article during the painting process will form. Dust, such as direct discharge, will cause air pollution. Therefore, most of the painting and painting operations are carried out in the painting room where the water-washing type spray booth is installed. The structure of the conventional water-washing paint booth is provided with a water curtain screen, a sump, and a pipe. The fan group, and the water curtain screen is formed by a water pipe to form a water wall, and the water flowing along the water curtain screen is attached to the paint dust which is scattered at the time of the painting process, so that the dust flows into the water collecting tank along with the water flow, and at the same time borrows The suction force generated by the fan group can make most of the dust and paint generated during the painting work adhere to the water wall of the water curtain screen, and The water flows down into the sump and the clean air is discharged from the pipe to the outside air; however, although most of the paint dust can be carried into the sump by the water stream, a small portion is not attached to the water stream. The dust discharges the outside air through the pipeline, which fails to fully absorb the gas and granular pollutants in the dust, and still has a non-negligible influence on human health and the environment. Now, the environmental protection requirements are increasingly severe, and it still improves. Space and necessity.

The main purpose of this creation is to solve the above problems, and to provide a dust removal device. The main technology and purpose are: to let the dust pass through the spoiler, the metal filter unit, and the electrostatic dust collection unit in sequence, so that the step is gradually increased from coarse to subdivided. In addition, it can effectively absorb pollutants to reduce environmental pollution and avoid harm to the environment and human body.

According to the above object of the present invention, there is provided a dust removing device for treating exhaust gas and dust, comprising: a box body having an inlet and an outlet at each end; a spoiler disposed in the box and adjacent to the box a plurality of uniformly arranged through holes are disposed on the surface; at least one metal mesh unit is disposed at a rear end of the spoiler; and at least one electrostatic dust collecting unit is disposed at a rear end of the metal mesh unit The exit.

In an embodiment of the present invention, the two sides of the spoiler are not attached to the box to form a channel space.

In an embodiment of the present invention, a first collecting groove is disposed at a bottom of the box to correspond to the metal mesh unit.

In an embodiment of the present invention, the first collecting trough has a discharge hole.

In an embodiment of the present invention, a dumping plate is disposed at the bottom of the electrostatic precipitator unit.

In an embodiment of the present invention, a second collecting groove is disposed at a bottom of the box to correspond to the dumping plate.

In an embodiment of the present invention, the second collecting trough has a discharge hole.

According to the above structure, the exhaust gas and the dust can pass through the dust removing device and pass through the electrostatic dust collecting unit, so that the pollutants are adsorbed and collected, thereby achieving an efficient filtering and dust removing effect.

In order to enable the review board to have a better understanding of the present work, a preferred embodiment will be described in conjunction with the drawings. Details are as follows: Please refer to Figures 1 to 4, which includes a case 11 with one at each end. An inlet 12 and an outlet 13; a spoiler 14 is formed in a plate shape and disposed in the casing 11 and adjacent to the inlet 12, and a plurality of uniformly arranged through holes 141 are disposed on the surface thereof, and the spoiler 14 is The side is not attached to the casing 11 to form a passage space 142; at least one metal screen unit 15 is disposed at the rear end of the spoiler 14, and the bottom of the casing 11 is provided with a first discharge hole 171. The collecting tank 17 corresponds to the metal screen unit 15; and at least one electrostatic precipitating unit 16 is disposed at the rear end of the metal screen unit 15 and adjacent to the outlet 13. The bottom portion is provided with a dumping plate 18, and the tank 11 is provided. A second collecting groove 19 having a discharge hole 191 is disposed at the bottom corresponding to the dumping plate 18; by the above structure, the exhaust gas and the dust can pass through the dust removing device 10 and pass through the electrostatic dust collecting unit 16 to cause the pollutant to be adsorbed. Collect and achieve efficient filtration and dust removal.

The composition and function of the above embodiment are described in detail as follows: Referring to Figures 1 to 4, firstly, the present invention introduces exhaust gas and dust from the inlet 12 into the casing 11, passes through the spoiler 14 and passes through the spoiler 14 The through hole 141 and the passage space 142 on both sides form a split flow, which blocks the exhaust gas and the dust to slow down the speed, thereby increasing the overall time of passing through the metal screen unit 15 and the electrostatic precipitator unit 16, and the exhaust gas, The dust can be evenly dispersed in the box 11, so that the optimal filtering effect can be achieved; and when the exhaust gas and dust pass through the metal screen unit 15, the larger and coarser pollutants can be filtered first, and Can be received by the first collecting trough 17 at the bottom of the box 11 The contaminants dropped by the metal screen unit 15 or having a high water content are liquid, and are excluded from the discharge holes 171 of the first collection tank 17 to be externally collected.

According to the above, the exhaust gas and the dust are passed through the electrostatic precipitator unit 16, and the smaller and finer contaminants can be collected and filtered, and guided by the dumping plate 18 to be dropped by the electrostatic precipitator unit 16. Contaminants that fall or have a high water content in liquid form fall into the second collecting tank 19, and are excluded from the discharge holes 191 of the second collecting tank 19 to be externally collected. In detail, the electrostatic precipitator unit 16 utilizes the property of attracting light and small objects by static electricity, and firstly imparts a certain amount of charge (ionization) to the dust particles of the exhaust gas and the dust, and then applies an electric field to the applied electric field. Such charged contaminants are attracted to an electrostatic precipitator unit 16 having an opposite charge to the contaminant; then, the filtered air is then discharged to the outside air via the outlet 13.

As described above, the present invention slows down the dust flow rate by the spoiler 14, and filters out the coarser contaminants by the metal screen unit 15, and then filters out the finer contaminants by the electrostatic precipitator unit 16 Step-by-step segmentation filtering can efficiently absorb pollutants in exhaust gas and dust. According to this creation, the environmental pollution can be reduced and the environment and human body can be harmed.

However, the above-mentioned ones are only preferred embodiments of the present invention, and are not intended to limit the features of the present creation. The re-creation of the technical means and creation principles related to the creation is still the creative equivalent of the creation. .

In summary, the structure of this creation does have excellent practicality and enhanced efficiency. It is in line with the provisions of the Patent Law, and it is submitted in accordance with the law.
