Description

[Detailed description of the invention] This invention relates to an electrostatic precipitator equipped with multiple rooms.
This is intended to facilitate gas flow into the inlet of the dust collection chamber and to ensure that dust-containing water is collected when cleaning dust from the dust collection section.

In general, in electrostatic precipitators, an increase in the degree of dispersion in gas flow rate causes a decrease in dust collection performance, which in turn makes it necessary to increase the size of the dust collector.

In the case of a multi-chamber type, it is required to have a small loading load due to its structure.

In addition, if the type is equipped with a continuous room, dust and cleaning water may fall, especially if the
A drainage collection device that does not have to worry about splashing is required.

The present invention is provided to address these problems and demands, and its gist is that the electrostatic precipitator 3 is installed directly on the upper part 1 of the factory communication room, and the above-mentioned A plurality of primary drainage gutters 6 are arranged below each dust collection plate 4 in the electrostatic precipitator section and extend in a direction perpendicular to the thickness of the dust collection plate at regular intervals, A long cover T having an A-shaped cross-sectional shape or a shape similar to the above is provided at an interval t2 above the upper end of the primary drainage gutter 6 at the upper part of each interval of the primary drainage gutter. , the long cover (.) is provided so as to cover the interval part of the primary drainage gutter 6 and to have a constant interval t0 between the long covers, and is provided inside the long cover 7 and the primary drainage gutter. A plate 8 is provided as a water droplet in the vertical direction to be located at the center of each gap between the gutters 6 to partition the primary drain gutters 6, and a plate 8 is provided below each gap between the primary drain gutters 6. A continuous factory room characterized in that the water droplet tray is provided with a secondary drainage gutter 9 directly below the plate 8, and a gas flow path is formed by the spaced portions t1, t2, and t3. Located in the upper dust collector.

The present invention will be described below based on embodiments shown in the drawings.

In the figure, 2 is an electrostatic precipitator installed above the continuous room 1, and 5 is a discharge electrode.

Reference numeral 6 denotes a primary drainage gutter, which receives the dust and drainage water that falls when the dust collecting plate 4 is washed, and discharges it to the outside of the system.

The secondary drainage gutter 6 is provided so as to extend in a direction perpendicular to the width direction of the dust collecting plate 4, and a plurality of the primary drainage gutter 6 are arranged in a plane at regular intervals.

A wedge-shaped cover 7 is provided at a distance t2 above the secondary drainage gutter 6.

At that time, the covered 7 comrades that were horizontally spaced at a constant interval t
4 is provided.

Next, inside this cover 7, a plate 8 is provided as a water drip tray.

That is, the plate 8 of this water droplet tray is vertically provided inside the cover 7 and located at the center of each interval of the secondary drain troughs 6 so as to partition the troughs 6 from each other.

Next, a secondary drainage gutter 9 is provided below each interval of the secondary drainage gutter 6.

At this time, an interval t3 is provided in the upper direction between the secondary drainage gutter 6 and the secondary drainage gutter 9.

The above-mentioned interval part t1. t2. t3 becomes a gas flow path.

With this configuration, the gas can flow in smoothly and the drainage water and dust that fall can be reliably collected by reading the flow.

That is, the dust-containing gas rising inside the building is transferred to the space t3 between the drain gutter and the auxiliary gutter, between the drain gutter and the water drip pan, and further to the space t2. While passing through tl, the flow velocity distribution is made uniform, and the gas advances to the electrostatic precipitator 3, where it is collected and released into the atmosphere as clean gas.

On the other hand, the dust in the gas collected by the dust collecting plate 4 in the electrostatic precipitator 3 is removed from the dust collecting plate 4 with washing water by a cleaning device and collected in the drain gutter 6.

At this time, when water droplets hit the drainage gutter 6, water droplets are generated and scattered, but these are reliably collected by the water droplet tray 8 and the secondary gutter 9.

The drainage gutter drains the reading water to the outside of the machine and connects it to a collection gutter (not shown).
is sent to the wastewater treatment equipment.

Next, in the above configuration, the shape of the primary drainage gutter 6 is not particularly limited, but there are examples such as those shown in FIGS. 6-1 to 6-4.

In addition, as the hemlock-shaped cover 7, a hemlock-shaped cover 7 in a particularly strict sense is used.
It is not limited to 1, but also includes skewer type 7-2, etc.

Next, as the plate 8, the water drip tray may be a plate-shaped plate extending in the longitudinal direction of the gutter and provided in a straight position (although not limited to this, for example, as shown in Figs. 8-1 to 8-7). Something like this will be chosen.

That is, 8-2 is a hanging chain, and 8-3 is a hanging rod or wire.

(Note that figure a shows a side view, and figure b shows a cross section.

Next, as for the shape of the secondary drainage gutter 9, for example, FIG.
Those shown in Nos. 1 to 9-4 are appropriately selected.

According to the present invention as described above, there are the following effects.

■ It is possible to prevent washing water from falling into the building.

■ Easier to adjust wind speed distribution.

■ It is possible to adjust the wind speed distribution with the minimum necessary pressure loss, ensuring maximum ventilation capacity.
