た夛、また排出装置を設けない場合等は、シーズン終了
後の水槽の清掃に重労働を要していた。Most conventional wet dust collectors are of the type that combines a circulation tank and a settling tank, and the capacity of this water tank is 10 to 2 times the amount of circulating water.
They were often designed with a 0 minute capacity and required very large water tanks. As a result, sludge discharge equipment has become expensive, and in cases where a sludge discharge device is not installed, cleaning the aquarium after the season ends requires hard labor.
また、水槽からの排水も一度に大量の水を排水しなけれ

テム化したものである。In the embodiment shown in the figure, a net mist catcher (2) is installed on the open ceiling of the dust removal chamber (1), and a water spray shower (
3) At t-1, furthermore, install regulators (4) below the shower (3) and collect dust in the area below the regulator (4) on the side wall of the dust removal chamber (1). An air inlet (5) is provided, and an eave (6) is provided on the upper edge of the inlet (5), and a sedimentation chamber (7) is connected to the air inlet (5) via a duct (8). The bottom wall (9) of the dust removal chamber (1) is sloped so that the lower part of the eaves (6) is lowered, and a gutter (10) is attached to the hem edge of this bottom wall (9), and the dust removal chamber (1) K
A circulation tank α-ken with a front end wall (13 tilted upward toward the front and the other walls standing upright) is installed in parallel, and a box-shaped drainboard I with the front half of the wall tilted upwards is placed above the circulation tank a3. Portrait: r(
14) A coarse garbage application conveyor α is provided on the upper surface, and a coarse garbage falling member is provided at the front end of the same drainboard (14), and a partition wall fin is erected in the rear part of the circulation tank A barrel to separate the partition. A sludge pump is installed in the rear part of the wall αη, and a first sludge scraping conveyor a9 and a scum removal pump mt- are installed in the front part, as well as a circulation tank (first sludge drop port 31 at the front end of 13). In addition, a sedimentation tank (c) with a front end wall tilted upward toward the front and other walls upright is installed in the circulation tank a3, and a second sludge [scraping conveyor] is installed in this sedimentation tank (to). The same sedimentation 4 for cl bleeding! A second sludge fall port (c) is provided at the front end of each I (to), and a water supply pipe (1) to the circulation tank, and the washing water collected in the gutter α is transferred to a coarse dirt filtration conveyor (L!). Washing water pipe guided above 9 ■, for filtering scum water from the scum removal pump (2) for coarse dirt;

作 用〕
即ち、循環槽は循環水量の１〜２分容量程度であって従
来の方法の１７１０程度の容量でよい。[Function] That is, the circulation tank has a capacity of about 1 to 2 minutes of the amount of circulating water, and may have a capacity of about 1,710 times the amount of circulating water.

ジを汚泥かき出し；ンペアにて排出する。Water is used in circulation, and coarse waste such as straw waste is filtered out by a conveyor before it flows into the circulation tank, and foaming and scum generation in the circulation tank is suppressed by installing a scum removal pump, etc. , part of the circulating water from the circulation tank (1 to 1 of the circulating water amount)
The sludge is sent to a sedimentation tank using a sludge pump, and allowed to stay in the sedimentation tank for a sufficient time (30 to 60 minutes), and the settled sludge is scraped out and discharged using a pump.

利点がある。Further, the water that has been separated by sedimentation WK is allowed to overflow and returned to the circulation tank, and is also drained. Therefore, according to this method, dust in the 20 to 50 micron class, which was conventionally difficult to settle, can be settled and separated, and the tank capacity can also be reduced, making it easier to clean the tank in the off-season. This method has the advantage of requiring less installation space compared to conventional methods.
