Description

[Detailed Description of the Invention] The present invention relates to a mobile multi-room electric collector that allows several single electrostatic precipitators to be assembled into a large-capacity machine of a type corresponding to the purpose of use on site. I'll go.

Conventional dust collectors have the disadvantage that as their capacity increases, their bodies become larger, making them difficult to transport and that they cannot be 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.) Its configuration will be explained with reference to the drawings. 1 Figure 1 shows the mobile multi-chamber electrostatic precipitator of the present invention. FIG.

In the drawing, / is a single long cylindrical unit), and several of these are installed on the left and right (top and bottom), or on the top, bottom, left and right, and are used as seven machines.

Each unit has a suction port 3 and an air exhaust hole with front and rear rotational flow generating parts, each consisting of several radial fall fixed inclined blades, at the front and rear ends of the long cylindrical outer cylinder unit. ) A large number of slits G are provided on the cylindrical surface behind the rotational flow generating section S on the suction port side.
A tapered conical separation cylinder 7 with a discharge rod /θ in the center
m) Install a net-type dust collection pole.

In addition, the wire mesh that constitutes the dust collection pole in the example in the figure has a coarse mesh 9 in front of it.
a) The rear row is knitted with close stitch b.

In addition, an annular space // is provided between the separation cylinder 7 and the inner surface of the outer cylinder on the outside of the separation cylinder 7 and the dust collection pole) 4J1 A part of the dust JJ + outlet / 3 is provided behind the rotating flow generating part B on the air outlet side. An annular dust collecting groove 7.2 is formed therein.

Figures 2 and 3 are side and rear views of a mobile multi-chamber electrostatic precipitator according to the present invention, in which several of the above-mentioned units are installed vertically and horizontally. K) Attach a common hopper, 2/, to the suction port of each unit, and install a blower 22 at the inlet of the hopper.
A common dust collection box 23 is attached to the dust collection groove/2 and the discharge path/3 at the rear end of each unit.

Next, the effect will be explained.

The airflow containing different dusts of various school regulations blown into the hopper 2/) is distributed to each unit 1.

The airflow that has entered each unit turns into a rotating airflow in the rotational flow generating section, and first, large particles of dust are separated and discharged into the sulin l-g space by centrifugal force in the separation cylinder. Airflow containing dust flows through the dust collection section. In between, the dust is charged and attracted to the assembly surface, and the airflow moving in the centrifugal direction from inside the A cylinder creates a space.
/ is discharged.

If the mesh of the section is organized as shown in the figure, the first stage is coarse, and the second stage is a) coarse, and the latter stage is two-stage, or coarse, and the second stage is three-stage, dense. Large-diameter particles that are subjected to a large force are first attracted to the mesh surface and then ejected to the outside.X/
The J diameter particles float inside the cylinder and migrate to the rear, where they are attracted to the highly charged dense mesh. Some of them are released outside the mesh, but a certain amount of ultrafine particles remaining on the mesh surface collects. After that, it is peeled off from the screen surface and sent to the rear of the cylinder along with the airflow advancing inside the cylinder, and a swirling force is further applied at the rotating flow generating part B on the exhaust port side, forming an annular shape together with the dust released into the space. Dust collection groove 7
．． 2, and is discharged to the outside of the unit from J:ll°output path/3.

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

The dust collector of the present invention aggregates the dust in the airflow sucked into the machine and collects it in the common dust collection box 23, so the subsequent disposal etc. Not only is it extremely easy to use, but since each unit is 1" type, it is possible to transport the number of units that can be loaded on trucks with various loading capacities.) At the site, only the required number can be transported according to the situation, depending on the purpose. 1 This makes it possible to apply it to construction sites in tunnels, where the installation space is narrow and requires a large amount of dust treatment, and there is no place to dispose of the collected dust, which was previously considered difficult. effective.
