【従来の技術】[Prior art]

図3に従来の空気・灰分離装置の1例を示す。 図において石炭灰の混入した空気はサイクロン23の上部位置に送られ、ここ で第一段の灰・空気のサイクロンによる分離がなされ、分離された灰は下方に落 下しゲート25を経てホッパ26に排出される。 FIG. 3 shows an example of a conventional air / ash separation device. In the figure, the air mixed with coal ash is sent to the upper position of the cyclone 23, where the ash and air in the first stage are separated by the cyclone, and the separated ash drops downward and passes through the gate 25 and the hopper 26. Is discharged to.

【0003】 一方該サイクロン23で分離された空気は該サイクロン頂部に接続された配管 を経てバグフィルタ21に移送される。On the other hand, the air separated by the cyclone 23 is transferred to the bag filter 21 via a pipe connected to the top of the cyclone.

【考案が解決しようとする課題】[Problems to be solved by the device]

ところで前述のような従来装置においては次に示すようないくつかの不具合点 がある。 (1)図3に示すゲート25,24はサイクロン23とバグフィルタ21の2段 階分離のためゲート2式を必要とするが、該ゲートは真空下でシールを行ない、 かつ連続的に灰を排出せねばならないため特殊仕様であり極めて高価であるため 装置全体がコスト高となる。 By the way, the conventional device described above has some problems as follows. (1) The gates 25 and 24 shown in FIG. 3 require two sets of gates to separate the cyclone 23 and the bag filter 21 into two stages, but the gate is sealed under vacuum, and the ash is continuously removed. Since it has to be discharged, it has a special specification and is extremely expensive, which increases the cost of the entire device.

【0009】 (2)真空源に機械式ブロワ(ルーツブロワ)を用いるので50mg/m3 程度 以下の灰濃度にする必要があるが、サイクロン一段では、灰と空気が前記許容で きる灰濃度にまで分離できず、どうしてもバグフィルタが必要となる。(2) Since a mechanical blower (roots blower) is used as the vacuum source, it is necessary to set the ash concentration to about 50 mg / m 3 or less, but in the cyclone one stage, the ash and air can reach the above-mentioned allowable ash concentration. It cannot be separated, and a bug filter is absolutely necessary.

【0010】 (3)またバグフィルタ一段では入口の灰濃度が高すぎる(入口灰濃度は数10 kg/m3 が空気輸送では一般的)ので、濾過風速を下げる(即ちフィルタ濾面 の面積を大きくする)ことが必要となる。(なお濾過風速は入口濃度数kg/m 3 において1〜1.5m/min程度)その結果生産性が低下する。(3) Further, the ash concentration at the inlet is too high with a single bag filter (the ash concentration at the inlet is several tens kg / m 2.3However, it is necessary to reduce the velocity of the filtering wind (that is, increase the area of the filtering surface). (Note that the filtration air velocity is several kg / m at the inlet concentration. 3 As a result, the productivity is reduced.

【0011】 本考案はこれら上記各不具合を解決し、コストダウンを図ると共に性能的に全 く変らない新たな石炭灰の真空輸送用空気・灰分離装置を提供することを目的と している。An object of the present invention is to solve the above-mentioned problems and to provide a new air / ash separation device for vacuum transportation of coal ash, which achieves cost reduction and does not change the performance completely.

The air thus introduced is introduced and separated into air and ash by the cyclone separator, and the separated ash falls downward due to its own weight.

【0014】 一方分離された空気はバグフィルタ上部に配設したフィルタにより更に濾過分 離されたのち真空ブロワにより機外に吸引排出される。On the other hand, the separated air is further filtered and separated by a filter arranged above the bag filter, and then sucked out of the machine by a vacuum blower.
