Description

[Detailed Description of the Invention] The present invention relates to a mobile multi-room electrostatic precipitator that allows several individual electrostatic precipitators to be assembled into a large-capacity machine of a type corresponding to the purpose of use on site. It is.

Conventional dust collectors have the drawback that as their capacity increases, their bodies become larger, which not only makes them difficult to transport, but also prevents them from being used in narrow sites such as tunnels.

The present invention was invented for the purpose of obtaining a large-capacity dust collector that does not have the above-mentioned drawbacks, and its configuration will be explained with reference to the drawings. Figure 1 shows the mobile multi-chamber electric dust collector of the present invention. FIG.

In the drawing, 1 is a long cylindrical single body, and several of these are installed on the top and bottom, left and right, or on the top and bottom and left and right to be used as a single body.

Each unit 1 has a suction port 3 and an exhaust port 4 provided at the front and rear ends of an elongated cylindrical outer cylinder 2, respectively, with front and rear rotating flow generating parts 5 and 6 each consisting of several radial fixed inclined blades. A tapered conical separating cylinder 7 having a large number of slits 8 on the cylinder surface and a cylinder mesh type dust collecting electrode 9 having a discharge rod 10 at the center are sequentially installed behind the rotational flow generating part 5 on the suction port side.

The wire mesh constituting the dust collection pole 9 in the illustrated example is knitted with a coarse mesh 9a at the front stage and a dense mesh 9b at the rear stage.

Further, an annular space 11 is provided on the outside of the separation tube 7 and the dust collection electrode 9 between the inner surface of the outer tube 2, and a dust discharge passage 13 is provided in a part behind the rotational flow generating section 6 on the exhaust port side. An annular dust collecting groove 12 is formed therein.

Figures 2 and 3 are side and rear views of an embodiment of the mobile multi-chamber electrostatic precipitator of the present invention, in which several of the above-mentioned units 1 are arranged side by side in the upper, lower, left and right directions, and each unit 1 is arranged in several rows. They are assembled in several stages and fixed by appropriate means, and a common hopper 21 is attached to the suction port of each unit, a blower 22 is arranged at the inlet of the hopper, and a discharge path of the dust collection groove 12 at the rear end of each unit is installed. 13 with a common dust collection box 23 attached thereto.

Next, the effect will be explained.

The airflow containing different dust particles of various particle types sucked into the hopper 21 is distributed to each unit 1.

The airflow that has entered each unit 1 becomes a rotational airflow in the rotational flow generation part 5, and first, large particles of dust are separated and released into the space 11 from the slit 8 by centrifugal force in the separation cylinder 7, and the remaining airflow containing dust is collected. It flows through the tube network of the spark pole 9. During this time, the dust is charged and attracted to the cylinder screen surface, and is discharged into the space 11 by the airflow moving in the centrifugal direction from inside the cylinder.

If the mesh of the tube mesh is organized in two stages, such as coarse mesh 9a in the front stage and dense mesh 9b in the rear stage, or three stages of coarse, medium, and dense mesh, as shown in the figure, the centrifugal force will be generated in the coarse mesh part where the amount of charge is small. The large-diameter particles, which receive a large amount of electricity, are first attracted to the mesh surface and then discharged to the outside, while the small-diameter particles float inside the cylinder and migrate to the rear, where they are attracted to the dense mesh with a large amount of electrical charge. The ultrafine particles that are discharged to the outside but remain on the mesh surface gather in a certain amount and then peel off from the mesh surface and are sent to the rear of the cylinder along with the airflow progressing inside the cylinder, where they are further collected in the rotating flow generator 6 on the exhaust port side. The turning force is applied and the dust released into the space 11 is released into the annular dust collection groove 12, and is discharged to the outside of the unit through the discharge passage 13.

Dust discharged from each unit is collected in a common dust collection box 23.

The dust collector of the present invention can intensively separate the dust in the airflow sucked into the machine in each unit 1 and collect them in the common dust collection box 23.
Not only is subsequent disposal extremely easy, but each unit 1 is small, so it is possible to transport as many units as possible on trucks with various loading capacities.
At the site, it is possible to assemble the required number in a manner according to the purpose depending on the situation, and this allows the installation space to be narrow, which was previously considered difficult, and requires large-capacity dust treatment. It has the advantage that it can be applied to construction sites inside tunnels where there is no place to dispose of dust.
