【発明の属する技術分野】
本発明は、ごみ焼却,各種の化学操作や物理操作において発生する粉塵を含んだガスから粉塵を除去する洗浄集塵装置に係り、特に、筒状塔体にガスを供給しこの筒状塔体内でガス中に含まれる粉塵を洗浄液で洗浄して捕集する洗浄集塵装置に関する。
【0002】
【従来の技術】
一般に、この種の洗浄集塵装置としては、例えば、図4に示すように、所謂ベンチュリースクラバーといわれるものが良く知られている。この洗浄集塵装置Taは、筒体1のガス供給部2からガスを供給し筒体1の開口面積を絞った絞り部3を通過させるとともに、絞り部3の手前から水などの洗浄液を噴射ノズル4から噴射し、この噴射される洗浄液を液滴にしてガスとを混合した混合ガスにし、粉塵をこの液滴で捕集して洗浄するとともに、この混合ガスを後流のサイクロン分離器5を通し洗浄液とガスとを分離し、ガスをガス排出部6から排出し、洗浄液は筒体下部の排出口7から排出させるようにしている。
【0003】
また、一般に、この種の洗浄集塵装置としては、例えば、図5に示すように、所謂転流式スクラバーといわれるものも良く知られている。この洗浄集塵装置Tbは、筒状塔体10の下部内部に洗浄液を溜め、溜められた洗浄液へガス供給部11からガスを高速で衝突させ、衝突による慣性集塵作用とその際に生じる液滴による洗浄効果で粉塵を捕集し、ガス中の液滴はエリミネータ12で分離し、ガスを筒状塔体10の上部に設けたガス排出部13から排出するようにしている。
【0004】
更に、従来において、洗浄集塵装置としては、例えば、特許文献1(特開平6−170142号公報)に掲載されたものもある。この洗浄集塵装置Tcは、図6に示すように、筒状塔体20の下部内部に洗浄液を溜め、溜められた洗浄液中へガス供給部21からガスを吹き込み、この洗浄液で先ず粉塵を捕集するとともに、筒状塔体20の内部空間に網状部材22を多段に設け、各網状部材22にスプレーノズル23から洗浄液を供給して液膜を形成し、この網状部材22に形成された液膜にガスを通過させて、液膜により粉塵を捕集して洗浄するとともに、このガスをエリミネータ24を通して洗浄液とガスとを分離し、ガスを筒状塔体20の上部に設けたガス排出部25から排出するようにしている。
【0005】
【特許文献1】
特開平6−170142号公報
【0006】
【発明が解決しようとする課題】
ところで、上記従来の洗浄集塵装置にあって、先ず、最初の所謂ベンチュリースクラバーといわれるタイプの洗浄集塵装置Taでは、液滴の発生する所は絞り部3の1ヶ所であり、そのため、粉塵を液滴で十分に捕集しきれないという問題があった。特に、ガス中に含まれる粉塵の径のバラツキが大きいときや、性質の異なる粉塵が混ざっているときなどには、捕集効率が悪くなり、所要動力を増加させる等の問題があった。
【0007】
また、上記従来の洗浄集塵装置にあって、第二に挙げた所謂転流式スクラバーといわれるタイプの洗浄集塵装置Tbにあっても、液滴の発生する所はガスが衝突する洗浄液面14のところの1ヶ所であり、そのためこのタイプのものでも、粉塵を液滴で十分に捕集しきれないという問題があった。特に、ガス中に含まれる粉塵の径のバラツキが大きいときや、性質の異なる粉塵が混ざっているときなどには、捕集効率が悪くなり、所要動力を増加させる等の問題があった。
【0008】
一方、上記従来の洗浄集塵装置にあって、第三に挙げた洗浄集塵装置Tcにあっては、液膜を形成する網状部材22を多段に設けているので、ガスがその都度液膜に接することから、上記の2つの周知のスクラバーTa,Tbに比較して、ガスの流速が比較的緩やかなので、液膜を通過するだけで洗浄液との混合が不十分になってしまい、このタイプのものでも、粉塵を十分に捕集しきれないという問題があった。特に、ガス中に含まれる粉塵の径のバラツキが大きいときや、性質の異なる粉塵が混ざっているときなどには、捕集効率が悪くなり、所要動力を増加させる等の問題があった。
【0009】
本発明は、このような問題に鑑みてなされたもので、液膜や液滴の発生する箇所を多段に設けるとともに、この箇所のガスの流速を、通過口の面積を変えることによって変化させ、発生する液滴の粒度を必要に応じて調節する。この液滴は粉塵とともにガスによって部分空間へ送られ、上部仕切り板と衝突して渦流となり、流動層を形成し、ガス中の粉塵と液滴の接触頻度を高め、粉塵の捕集効率を向上させた洗浄集塵装置を提供することを目的とする。
【0010】
【課題を解決するための手段】
上記のような課題を解決するための本発明の技術的手段は、筒状塔体の下部内部に洗浄液を溜め、該筒状塔体の下部に設けたガス供給部から上記溜められた洗浄液へガスを供給するとともに上記筒状塔体の上部に設けたガス排出部からガスを排出してガス中に含まれる粉塵を洗浄液で洗浄して集塵する洗浄集塵装置において、上記筒状塔体の内部空間を複数の仕切り板により上下に仕切って部分空間を形成し、隣接する部分空間間にガスが通過する通過口を形成し、上記溜められた洗浄液の液面より上位の通過口をガスの流速が大きくなるよう狭隘に形成し、上記内部空間に洗浄液を噴射する噴射ノズルを設けた構成としている。
【0011】
これにより、集塵を行なうときは、噴射ノズルから洗浄液を噴射させ、この状態で、ガス供給部からガスを供給する。ガスは、先ず、溜められた洗浄液内を通って通過口から次の部分空間内に吹き出していく。この場合、ガスが洗浄液と衝突する際粒径の大きな粉塵は慣性力で洗浄液中に捕集される。
【0012】
一方、比較的粒径の小さい粒子は一部、ガスや液滴と一緒に飛び出し、順次上位の部分空間内に流入していく。この場合、溜められる洗浄液の液面より上位の通過口は、ガスの流速が大きくなるよう狭隘に形成されているので、この通過口において、混合ガスの流速が大きくなり、高速となる。そのため、噴射ノズルからの洗浄液が高速のガス流によって、霧吹きの原理で細かい液滴となる。そして部分空間でガスは上部の仕切り板と衝突し渦流となり、ガス,粉塵,液滴の流動層を形成する。
【0013】
この流動層は、部分空間内に充満する状態となる。そのため、ガスと液滴とが良く混合し、これによって、粉塵の液滴に対しての接触頻度が高くなり、粉塵が液滴によく捕集されていく。このようにして、ガスが部分空間に順次流入することで、粉塵が確実に洗浄液に捕集されていくことになる。即ち、液膜や液滴の発生する箇所が多段に設けられ、しかも、この箇所のガスの流速を必要に応じて変え、発生する液滴の粒度を調整して流動層を発生させることができるので、ガス中の粉塵と洗浄液との接触頻度を高め、粉塵の捕集効率を向上させることができる。
【0014】
そして、必要に応じ、上記各複数の仕切り板を、下方に向けて傾斜形成し、該仕切り板の先端部側に上記通過口を形成した構成としている。仕切り板を下方に向けて傾斜形成したので、洗浄液は仕切り板を伝わってこの仕切り板の先端部から流下するようになる。そのため、仕切り板の先端部から流下する洗浄液の液膜を、狭隘な通過口を通過する高速のガス流によって巻き上げ、液滴を生成して、ガスと液滴とを激しく流動させることができ、より一層、粉塵の捕集効率を向上させることができる。
【0015】
また、必要に応じ、上記複数の仕切り板を、上位の仕切り板の先端部が下位の仕切り板の上面に対峙するように上記筒状塔体の対向する壁面から交互に突出させ、上記上側の仕切り板の先端部と下側の仕切り板の上面との間に上記狭隘の通過口を形成した構成としている。通過口が左右交互に形成されるので、ガスの流動層が蛇行するようになり、限られた空間内で流動層を数多く形成することができ、ガス中の粉塵と洗浄液との接触頻度を高め、粉塵の捕集効率を向上させることができる。
【0016】
更に、必要に応じ、上記噴射ノズルを、上記各狭隘の通過口毎に洗浄液を噴射するよう複数設けた構成としている。狭隘の通過口毎に洗浄液が供給されるので、各通過口での高速のガス流によって液滴を発生させることができ、このため、より一層、粉塵と洗浄液との接触頻度を高め、粉塵の捕集効率を向上させることができる。
【0017】
更にまた、必要に応じ、上記噴射ノズルの噴射口を上記狭隘の通過口の上側近傍に設けた構成としている。洗浄液が狭隘の通過口近傍から供給されるので、高速ガスによって発生する液滴は、粉塵とともにガスによって部分空間へ送られ上部仕切り板と衝突して渦流となり、流動層を形成する。
【0018】
また、必要に応じ、上記最下位の仕切り板をその先端部が上記溜められた洗浄液内に位置するように設けるとともに、ガス供給部のガス出口を上記最下位の仕切り板の下側であって上記溜められた洗浄液の液面より上側に位置するように設けた構成としている。これにより、ガス供給部からガスが供給されると、粉塵を含むガスは仕切り板の下面に沿って洗浄液の液面と衝突するとともに、部分空間の圧力が高くなるので、ガスは、洗浄液内を通って通過口から次の部分空間内に吹き出していく。そのため、この洗浄液に衝突することで、ガス内の粉塵を慣性作用で捕集することができるようになり、この点でも、粉塵の捕集効率を向上させることができる。
【0019】
【発明の実施の形態】
以下、添付図面に基づいて本発明の実施の形態に係る洗浄集塵装置を説明する。
本発明の実施の形態に係る洗浄集塵装置は、図1に示すように構成される。この洗浄集塵装置Tは筒状塔体30を備えている。塔体30の下部内部には、水や薬液などの洗浄液Wが溜められる。31は塔体30下部に設けられ溜められた洗浄液Wを排出弁31aの操作により適時に排出する排出口である。
【0020】
この塔体30の下部には、溜められた洗浄液Wへガスを供給するガス供給部32が設けられている。ガス供給部32は、その外部から内部に延びるガス供給管33を備えている。また、塔体30の上部にはガス排出部34が形成されている。
【0021】
筒状塔体30の内部空間Sは、複数の仕切り板40(40a,40b,40c,40d)により上下に仕切られており、この仕切り板40(40a,40b,40c,40d)により部分空間Sa,Sb,Sc,Sd,Seが形成されている。また、隣接する部分空間Sa,Sb,Sc,Sd,Se間には、ガスが通過する通過口41が形成されている。この通過口41のうち溜められる洗浄液Wの液面より上位の通過口41は、ガスの流速が大きくなるよう狭隘に形成されている。
【0022】
詳しくは、各複数の仕切り板40(40a,40b,40c,40d)は、下方に向けて傾斜形成され、上位の仕切り板40の先端部42が下位の仕切り板40の上面43に対峙するように筒状塔体30の対向する壁面30a,30bから交互に突出させられている。そして、仕切り板40(40a,40b,40c,40d)の先端部42側に通過口41を形成している。そして、上側の仕切り板40の先端部42と下側の仕切り板40の上面43との間の通過口41が、狭隘に形成されている。
【0023】
即ち、図1に示す集塵装置TをA−A方向から見ると、図2に示すように、塔体30が角筒の場合、壁面30aから突出した上側の仕切り板40dの先端部42は、壁面30bから突出した下側の仕切り板40cの取付部側に位置し、上側の仕切り板40dの先端部42と下側の仕切り板40cの上面43との間の通過口41が、狭隘に形成されている。
【0024】
また、塔体30が円筒の場合も、図3に示すように、図1に示す集塵装置TをA−A方向から見ると、壁面30aから突出した上側の仕切り板40dの先端部42は、壁面30bから突出した下側の仕切り板40cの取付部側に位置し、上側の仕切り板40dの先端部42と下側の仕切り板40cの上面43との間の通過口41が、狭隘に形成されている。
【0025】
更に、各仕切り板40(40a,40b,40c,40d)の傾斜角度は、仕切り板40上に落下した洗浄液Wが通過口41へ向けて流下できるように適度な角度に設定される。
【0026】
また、最下位の仕切り板40aは、その端部が溜められた洗浄液W内に位置するように設けられている。即ち、溜められる洗浄液Wは、最下位の仕切り板40aの先端部42が洗浄液W内に没入するように塔体30内に注入されている。
この最下位の仕切り板40aの先端部42により形成される通過口41(A)には、この仕切り板40aの先端部42に対峙してガスを上位の部分空間Sbに導くガイド板44が設けられている。
【0027】
そして、ガス供給部32のガス供給管33の出口33aは、最下端の部分空間Saに開口しており、即ち、最下位の仕切り板40aの下側であって溜められた洗浄液Wの液面より上位に位置するように設けられている。
【0028】
更に、本装置Tにおいては、内部空間Sに洗浄液Wを噴射する噴射ノズル50が設けられている。噴射ノズル50は、各狭隘の通過口41毎に洗浄液Wを噴射するよう複数設けられている。噴射ノズル50の噴射口51は、狭隘の通過口41の上側近傍に設けられている。即ち、噴射ノズル50は最下位の部分空間Saより上位の部分空間Sc,Sd,Se毎に狭隘の通過口41の上側近傍で洗浄液Wを噴射するよう設けられている。
【0029】
噴射ノズル50は、塔体30に溜められる洗浄液Wが循環して供給するポンプ装置52に接続されている。また、ポンプ装置52は、新鮮な洗浄液Wの供給管路53にも接続されており、切換えにより、噴射ノズル50に新鮮な洗浄液Wを補充できるように構成されている。
【0030】
更にまた、最上位の部分空間Seにおいて、ガス排出部34の前位には、洗浄液Wとガスとを分離する周知のエリミネータ54が設けられている。
【0031】
従って、上述したような構造の洗浄集塵装置Tでは、次のようにしてガスの集塵が行なわれる。
ポンプ装置52は常時作動しており、噴射ノズル50からは、洗浄液Wが噴射されている。これにより、噴射された洗浄液Wは仕切り板40(40a,40b,40c,40d)に落下し、仕切り板40(40a,40b,40c,40d)を伝わって流下していく。
この状態で、ガス供給部32のガス供給管33からガスが供給されると、ガスは、最下位の部分空間Sa内に供給される。これにより、粉塵を含むガスは仕切り板40aの下面に沿って洗浄液Wの液面と衝突するとともに、部分空間Saの圧力が高くなるので、ガスは、洗浄液W内を通って通過口41から次の部分空間Sb内に吹き出していく。この場合、先ず、この洗浄液Wに衝突することで、ガス内の粉塵が捕集される。次にまた、この洗浄液Wを通過することで、ガス内の粉塵が捕集される。このとき、比較的粒径の大きな粉塵は水中で捕集されるが、比較的粒径の小さい粒子は一部、ガスや液滴と一緒に部分空間Sb内に吹き出していく。
【0032】
通過口41(A)には、ガスを導くガイド板44が設けられているので、この部位が狭隘になっており、そのため、ガスが上位の部分空間Sb内に噴出していく。これにより、洗浄液Wが液滴となって、部分空間Sb内に流動することになる。そのため、ガスと液滴とが良く混合し、これによって、粉塵の液滴に対しての接触頻度が高くなり、粉塵が液滴によく捕集される。
【0033】
次に、液滴とガスとが混合した混合ガスは、通過口41から次の部分空間Sc内に流入する。この場合、通過口41は狭隘に形成されているので、この通過口41において、混合ガスの流速が大きくなり、高速となる。そのため、洗浄液Wは仕切り板40bを伝わって流下しているが、この仕切り板40bを伝わってその先端部42から流下する洗浄液Wの液膜は、高速のガス流によって、巻き上げられ、細かい液滴となる。更に、通過口41近傍からは噴射ノズル50から洗浄液Wが噴出しているので、この噴出する洗浄液Wも高速のガス流によって細かい液滴となり部分空間Sc内で、ガス,液滴,粉塵は渦流となり流動層を形成する。
【0034】
この流動層は、部分空間Sc内に充満する状態となる。そのため、ガスと液滴とが良く混合し、これによって、粉塵の液滴に対しての接触頻度が高くなり、粉塵が液滴によく捕集されていく。この流動層で捕集されなかった粉塵はガスと一緒に、更に次の通過口41から次の部分空間Sd内に流入する。
【0035】
この場合も、通過口41は狭隘に形成されているので、この通過口41において、混合ガスの流速が大きくなる。一方、部分空間Sdで、流動後分離された洗浄液Wは仕切り板40cを伝わって流下しているが、この仕切り板40cを伝わってその先端部42から流下する洗浄液Wの液膜は、高速のガス流によって、巻き上げられ、細かい液滴となる。更に、通過口41近傍からは噴射ノズル50から洗浄液Wが噴出しているので、ここから噴出する洗浄液Wも高速のガス流によって細かい液滴となり、高速の液滴や粉塵を含むガスは上部の仕切り板40dと衝突して渦流となり流動層を形成する。
【0036】
この流動層は、部分空間Sd内に充満する状態となる。そのため、ガスと液滴とが良く混合し、これによって、粉塵の液滴に対しての接触頻度が高くなり、粉塵が液滴によく捕集される。このようにして、部分空間Sa,Sb,Sc,Sd,Seに順次流入することで、粉塵が確実に洗浄液Wに捕集されていくことになり、粉塵の捕集効率を向上させることができる。
【0037】
また、仕切り板40(40a,40b,40c,40d)を筒状塔体30の対向する壁面30a,30bから交互に突出させたので、通過口41が左右交互に形成されることになり、そのため、ガスの流動層が蛇行するようになることから限られた空間内に多数の流動層を発生させることができ、この点でも、ガス中の粉塵と洗浄液Wとの接触頻度を高め、粉塵の捕集効率を向上させることができる。
【0038】
更に、噴射ノズル50を、各狭隘の通過口41毎に洗浄液Wを噴射するよう複数設け、狭隘の通過口41毎に洗浄液Wが供給されることにより、各通過口41での高速のガス流によって細かい液滴を多く形成できることから、より一層、粉塵と洗浄液Wとの接触頻度を高め、粉塵の捕集効率を向上させることができる。
【0039】
ガスが、最上位の部分空間Seからガス排出部34に至ろうとすると、エリミネータ54により洗浄液Wとガスとが分離され、洗浄液Wは落下して、次の捕集用に供されるとともに、ガスはガス排出部34から塔体30の外部に排出されていく。
【0040】
実験によれば、通常の集塵では、塔体30を2枚の仕切り板40で仕切り、洗浄液Wの溜められる下位の部分空間を含めて3個の部分空間を持つことで十分な集塵が可能で所要動力も少なくできることが確認された。ガス中の粉塵の径が、非常に小さい場合や粉塵が洗浄液Wに濡れにくい場合は、仕切り板40と仕切り板40の間隔を狭くしたり、仕切り板40の数を増やし、部分空間の数を増やすことによって満足の行く集塵が可能となる。また、洗浄液Wとガスとの分離後の下流側に所謂バクフィルタを設けることも不要になる。即ち、ガス中の粉塵径や濃度,粉塵の性質,除塵率に応じた集塵装置の設計が可能であるから、所要動力も制作費も少なくすることが可能な集塵装置である。
【0041】
尚、上記実施の形態において、噴射ノズル50の噴射口51は、狭隘の通過口41の下側近傍に設けても良い。また、最下位側の部分空間Sa,Sbにも設けるようにしても良い。また、噴射ノズル50の数は上述したものに限定されず、例えば、最上位の部分空間Seにのみ設けたり、各部分空間Sa,Sb,Sc,Sd,Se毎に複数設ける等、適宜変更して差支えない。また、取り扱うガスは、ごみ焼却,各種の化学操作や物理操作において発生するどのようなガスであってもよいことは勿論である。
【0042】
【発明の効果】
以上、説明したように、本発明に係る洗浄集塵装置によれば、筒状塔体の内部空間を複数の仕切り板により上下に仕切って部分空間を形成し、隣接する部分空間間にガスが通過する通過口を形成し、溜められる洗浄液の液面より上位の通過口をガスの流速が大きくなるよう狭隘に形成し、内部空間に洗浄液を噴射する噴射ノズルを設けた構成としたので、ガス中の粉塵を、先ず、溜められた洗浄液で捕集できるとともに、狭隘の通過口を通過させてガスの流速を高速とし、噴射ノズルからの洗浄液を高速のガス流によって細かい液滴とし、高速の液滴,粉塵を含むガスを上部の仕切り板と衝突させて渦流を発生させ、流動層を形成することができ、そのため、粉塵の液滴に対しての接触頻度を高め、粉塵を確実に洗浄液に捕集することができるようになる。即ち、本発明によれば、液膜や液滴の発生する箇所を多段に設け、しかも、この箇所のガスの流速を速くして細かい水滴を発生させ、部分空間内でガス,液滴,粉塵の流動層を発生させ、ガス中の粉塵と洗浄液との接触頻度を高め、粉塵の捕集効率を向上させることができるのである。

[Problems to be solved by the invention]
By the way, in the above-mentioned conventional cleaning and dust collecting apparatus, first, in the first type of cleaning and dust collecting apparatus Ta of a so-called Venturi scrubber, a place where a droplet is generated is one place of the throttle unit 3, and therefore, There is a problem that liquid droplets cannot be sufficiently collected. In particular, when the diameter of the dust contained in the gas has a large variation or when dusts having different properties are mixed, there is a problem that the collection efficiency is deteriorated and the required power is increased.
[0007]
Further, in the above-mentioned conventional cleaning and dust collecting apparatus, even in the cleaning dust collecting apparatus Tb of the type referred to as a so-called commutation type scrubber, the place where the droplets are generated is the cleaning liquid level where the gas collides. There is a problem in that the dust cannot be sufficiently collected by droplets even with this type. In particular, when the diameter of the dust contained in the gas has a large variation or when dusts having different properties are mixed, there is a problem that the collection efficiency is deteriorated and the required power is increased.
[0008]
On the other hand, in the above-mentioned conventional cleaning and dust collecting apparatus, in the cleaning and dust collecting apparatus Tc described above, since the mesh member 22 for forming the liquid film is provided in multiple stages, the gas is discharged each time. Since the gas flow rate is relatively slow as compared with the above-mentioned two known scrubbers Ta and Tb, mixing with the cleaning liquid is insufficient only by passing through the liquid film. However, there was a problem that dust could not be sufficiently collected. In particular, when the diameter of the dust contained in the gas has a large variation or when dusts having different properties are mixed, there is a problem that the collection efficiency is deteriorated and the required power is increased.
[0009]
The present invention has been made in view of such a problem, and in addition to providing multiple locations where liquid films and droplets are generated, and changing the gas flow rate at this location by changing the area of the passage port, The particle size of the generated droplet is adjusted as needed. These droplets are sent to the subspace by the gas together with the dust, collide with the upper partition plate and form a vortex, forming a fluidized bed, increasing the frequency of contact between the dust and the droplets in the gas, and improving the dust collection efficiency It is an object of the present invention to provide a cleaning and dust collecting apparatus which is made to perform the cleaning.
[0010]
[Means for Solving the Problems]
The technical means of the present invention for solving the above-mentioned problem is to store a cleaning liquid inside a lower portion of a cylindrical tower body, and from a gas supply unit provided at a lower portion of the cylindrical tower body to the stored cleaning liquid. In the cleaning and dust collecting apparatus for supplying gas and discharging gas from a gas discharge unit provided at an upper portion of the cylindrical tower body to wash and collect dust contained in the gas with a cleaning liquid, the cylindrical tower body The internal space is divided up and down by a plurality of partition plates to form a partial space, a passage port through which gas passes between adjacent partial spaces is formed, and a passage port higher than the liquid level of the stored cleaning liquid is formed by gas. Is formed so as to be narrow so as to increase the flow velocity, and an injection nozzle for injecting the cleaning liquid into the internal space is provided.
[0011]
Thus, when dust collection is performed, the cleaning liquid is injected from the injection nozzle, and in this state, the gas is supplied from the gas supply unit. First, the gas passes through the stored cleaning liquid and blows out from the passage port into the next partial space. In this case, when the gas collides with the cleaning liquid, dust having a large particle diameter is collected in the cleaning liquid by inertia.
[0012]
On the other hand, some particles having a relatively small particle diameter jump out together with the gas and the liquid droplets, and sequentially flow into the upper partial space. In this case, the passage above the liquid level of the stored cleaning liquid is formed so as to be narrow so that the flow velocity of the gas is increased. Therefore, the flow velocity of the mixed gas is increased at this passage, thereby increasing the speed. Therefore, the cleaning liquid from the injection nozzle is turned into fine droplets by the principle of atomization due to the high-speed gas flow. Then, in the partial space, the gas collides with the upper partition plate to form a vortex, forming a fluidized bed of gas, dust, and droplets.
[0013]
The fluidized bed fills the subspace. As a result, the gas and the droplets are well mixed, whereby the frequency of contact of the dust with the droplet increases, and the dust is collected by the droplet. In this way, the gas flows into the partial space sequentially, so that the dust is surely collected by the cleaning liquid. That is, the location where the liquid film or the droplet is generated is provided in multiple stages, and the fluid velocity can be changed by changing the gas flow rate at this location as needed, and adjusting the particle size of the generated droplet. Therefore, the frequency of contact between the dust in the gas and the cleaning liquid can be increased, and the dust collection efficiency can be improved.
[0014]
If necessary, each of the plurality of partition plates is formed to be inclined downward, and the passage port is formed at the tip end side of the partition plate. Since the partition plate is inclined downward, the cleaning liquid flows down the partition plate and flows down from the tip of the partition plate. Therefore, the liquid film of the cleaning liquid flowing down from the leading end of the partition plate is wound up by the high-speed gas flow passing through the narrow passage, and droplets are generated, so that the gas and the droplets can violently flow, The dust collection efficiency can be further improved.
[0015]
Further, if necessary, the plurality of partition plates are alternately protruded from opposing wall surfaces of the cylindrical tower body such that the tips of the upper partition plates face the upper surfaces of the lower partition plates, and The narrow passage opening is formed between the tip of the partition plate and the upper surface of the lower partition plate. Since the passage openings are formed alternately on the left and right, the fluidized bed of gas is meandering, and a large number of fluidized beds can be formed in a limited space, increasing the frequency of contact between the dust in the gas and the cleaning liquid. In addition, dust collection efficiency can be improved.
[0016]
Further, if necessary, a plurality of the spray nozzles are provided so as to spray the cleaning liquid to each of the narrow passage ports. Since the cleaning liquid is supplied to each of the narrow passages, droplets can be generated by the high-speed gas flow at each of the passages, and therefore, the frequency of contact between the dust and the cleaning liquid is further increased, and the dust is removed. The collection efficiency can be improved.
[0017]
Furthermore, if necessary, the injection port of the injection nozzle is provided near the upper side of the narrow passage port. Since the cleaning liquid is supplied from the vicinity of the narrow passage, the droplets generated by the high-speed gas are sent to the partial space by the gas together with the dust and collide with the upper partition plate to form a vortex, thereby forming a fluidized bed.
[0018]
Further, if necessary, the lowermost partition plate is provided so that the tip end thereof is located in the stored cleaning liquid, and the gas outlet of the gas supply unit is below the lowermost partition plate. It is configured to be provided above the liquid level of the stored cleaning liquid. Thus, when the gas is supplied from the gas supply unit, the gas including dust collides with the liquid surface of the cleaning liquid along the lower surface of the partition plate, and the pressure in the partial space increases. Pass through and blow out from the passage into the next subspace. Therefore, by colliding with the cleaning liquid, dust in the gas can be collected by inertia, and in this respect, the dust collection efficiency can be improved.
[0019]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, a cleaning and dust collecting apparatus according to an embodiment of the present invention will be described with reference to the accompanying drawings.
The cleaning and dust collecting apparatus according to the embodiment of the present invention is configured as shown in FIG. The cleaning and dust collecting apparatus T includes a tubular tower 30. A cleaning liquid W such as water or a chemical liquid is stored in the lower part of the tower 30. Reference numeral 31 denotes a discharge port provided at a lower portion of the tower body 30 for discharging the stored cleaning liquid W in a timely manner by operating the discharge valve 31a.
[0020]
A gas supply unit 32 that supplies gas to the stored cleaning liquid W is provided below the tower 30. The gas supply unit 32 includes a gas supply pipe 33 extending from the outside to the inside. Further, a gas discharge part 34 is formed in an upper part of the tower 30.
[0021]
The internal space S of the cylindrical tower body 30 is vertically divided by a plurality of partition plates 40 (40a, 40b, 40c, 40d), and the partial space Sa is defined by the partition plates 40 (40a, 40b, 40c, 40d). , Sb, Sc, Sd, and Se are formed. A passage 41 through which gas passes is formed between the adjacent partial spaces Sa, Sb, Sc, Sd, and Se. The passage port 41 of the passage port 41, which is higher than the level of the cleaning liquid W stored therein, is formed to be narrow so as to increase the gas flow velocity.
[0022]
More specifically, each of the plurality of partition plates 40 (40a, 40b, 40c, 40d) is formed so as to be inclined downward, so that the distal end portion 42 of the upper partition plate 40 faces the upper surface 43 of the lower partition plate 40. And protrude alternately from opposing wall surfaces 30a, 30b of the cylindrical tower body 30. And the passage opening 41 is formed in the front-end | tip part 42 side of the partition plate 40 (40a, 40b, 40c, 40d). Further, the passage opening 41 between the distal end portion 42 of the upper partition plate 40 and the upper surface 43 of the lower partition plate 40 is formed narrow.
[0023]
That is, when the dust collector T shown in FIG. 1 is viewed from the AA direction, as shown in FIG. 2, when the tower body 30 is a rectangular tube, the distal end portion 42 of the upper partition plate 40d protruding from the wall surface 30a is The passage 41 between the distal end portion 42 of the upper partition plate 40d and the upper surface 43 of the lower partition plate 40c, which is located on the mounting portion side of the lower partition plate 40c protruding from the wall surface 30b, is narrow. Is formed.
[0024]
Also, when the tower body 30 is a cylinder, as shown in FIG. 3, when the dust collector T shown in FIG. 1 is viewed from the AA direction, the distal end portion 42 of the upper partition plate 40 d protruding from the wall surface 30 a The passage 41 between the distal end portion 42 of the upper partition plate 40d and the upper surface 43 of the lower partition plate 40c, which is located on the mounting portion side of the lower partition plate 40c protruding from the wall surface 30b, is narrow. Is formed.
[0025]
Further, the inclination angle of each partition plate 40 (40a, 40b, 40c, 40d) is set to an appropriate angle so that the cleaning liquid W dropped on the partition plate 40 can flow down toward the passage 41.
[0026]
Further, the lowermost partition plate 40a is provided such that its end is located in the stored cleaning liquid W. That is, the stored cleaning liquid W is injected into the tower 30 so that the distal end portion 42 of the lowermost partition plate 40a is immersed in the cleaning liquid W.
A guide plate 44 that guides gas to the upper partial space Sb is provided at the passage opening 41 (A) formed by the distal end portion 42 of the lowermost partition plate 40a, facing the distal end portion 42 of the partition plate 40a. Have been.
[0027]
The outlet 33a of the gas supply pipe 33 of the gas supply part 32 is open to the lowermost partial space Sa, that is, the liquid level of the stored cleaning liquid W below the lowermost partition plate 40a. It is provided to be positioned higher.
[0028]
Further, in the present apparatus T, an injection nozzle 50 for injecting the cleaning liquid W into the internal space S is provided. A plurality of spray nozzles 50 are provided so as to spray the cleaning liquid W for each narrow passage port 41. The injection port 51 of the injection nozzle 50 is provided near the upper side of the narrow passage port 41. That is, the injection nozzle 50 is provided so as to inject the cleaning liquid W near the upper side of the narrow passage port 41 in each of the partial spaces Sc, Sd, Se higher than the lowermost partial space Sa.
[0029]
The injection nozzle 50 is connected to a pump device 52 that circulates and supplies the cleaning liquid W stored in the tower 30. Further, the pump device 52 is also connected to a supply pipe 53 for fresh cleaning liquid W, and is configured to be able to replenish the injection nozzle 50 with fresh cleaning liquid W by switching.
[0030]
Furthermore, in the uppermost partial space Se, a well-known eliminator 54 that separates the cleaning liquid W and the gas is provided in front of the gas discharge unit 34.
[0031]
Therefore, in the cleaning and dust collecting apparatus T having the above-described structure, gas dust is collected as follows.
The pump device 52 is constantly operating, and the cleaning liquid W is injected from the injection nozzle 50. As a result, the sprayed cleaning liquid W falls onto the partition plate 40 (40a, 40b, 40c, 40d) and flows down the partition plate 40 (40a, 40b, 40c, 40d).
In this state, when gas is supplied from the gas supply pipe 33 of the gas supply unit 32, the gas is supplied into the lowermost partial space Sa. As a result, the gas containing dust collides with the liquid surface of the cleaning liquid W along the lower surface of the partition plate 40a, and the pressure in the partial space Sa increases. Blows out into the subspace Sb. In this case, first, dust in the gas is collected by colliding with the cleaning liquid W. Next, the dust in the gas is collected by passing through the cleaning liquid W. At this time, dust having a relatively large particle diameter is collected in water, but a part of the particles having a relatively small particle diameter is blown out into the partial space Sb together with the gas and the droplet.
[0032]
The passage 41 (A) is provided with the guide plate 44 for guiding the gas, so that this portion is narrow, so that the gas blows out into the upper partial space Sb. As a result, the cleaning liquid W becomes droplets and flows into the partial space Sb. As a result, the gas and the droplets are well mixed, thereby increasing the frequency of contact of the dust with the droplet, and the dust is well collected by the droplet.
[0033]
Next, the mixed gas in which the droplet and the gas are mixed flows into the next partial space Sc from the passage 41. In this case, since the passage 41 is formed to be narrow, the flow velocity of the mixed gas at the passage 41 is increased and the speed is increased. For this reason, the cleaning liquid W flows down the partition plate 40b, and the liquid film of the cleaning liquid W flowing down from the distal end portion 42 along the partition plate 40b is wound up by the high-speed gas flow, and fine droplets are formed. It becomes. Further, since the cleaning liquid W is jetted from the injection nozzle 50 from the vicinity of the passage port 41, the jetted cleaning liquid W also becomes fine droplets by the high-speed gas flow, and the gas, the droplets, and the dust are swirled in the partial space Sc. To form a fluidized bed.
[0034]
This fluidized bed fills the partial space Sc. As a result, the gas and the droplets are well mixed, whereby the frequency of contact of the dust with the droplet increases, and the dust is collected by the droplet. Dust not collected by this fluidized bed flows into the next partial space Sd from the next passage 41 together with the gas.
[0035]
Also in this case, since the passage 41 is formed narrow, the flow velocity of the mixed gas at the passage 41 is increased. On the other hand, in the partial space Sd, the cleaning liquid W separated after flowing flows down the partition plate 40c, and the liquid film of the cleaning liquid W flowing down from the distal end portion 42 along the partition plate 40c has a high speed. The gas flow causes the liquid to be rolled up and formed into fine droplets. Further, since the cleaning liquid W is jetted from the injection nozzle 50 from the vicinity of the passage port 41, the cleaning liquid W jetted from the jet nozzle 50 is also turned into fine droplets by the high-speed gas flow, and the gas containing the high-speed droplets and dust is removed from the upper portion. It collides with the partition plate 40d and becomes a vortex to form a fluidized bed.
[0036]
This fluidized bed fills the partial space Sd. As a result, the gas and the droplets are well mixed, thereby increasing the frequency of contact of the dust with the droplet, and the dust is well collected by the droplet. In this way, by sequentially flowing into the partial spaces Sa, Sb, Sc, Sd, Se, the dust is surely collected by the cleaning liquid W, and the dust collection efficiency can be improved. .
[0037]
Further, since the partition plates 40 (40a, 40b, 40c, 40d) are alternately projected from the opposing wall surfaces 30a, 30b of the tubular tower 30, the passage openings 41 are formed alternately left and right. Since the fluidized bed of the gas is meandering, a large number of fluidized beds can be generated in a limited space. In this regard, the frequency of contact between the dust in the gas and the cleaning liquid W is increased, and the The collection efficiency can be improved.
[0038]
Further, a plurality of injection nozzles 50 are provided so as to inject the cleaning liquid W into each of the narrow passages 41, and the cleaning liquid W is supplied to each of the narrow passages 41. Thus, many fine droplets can be formed, so that the frequency of contact between the dust and the cleaning liquid W can be further increased, and the dust collection efficiency can be further improved.
[0039]
When the gas tries to reach the gas discharge section 34 from the uppermost partial space Se, the cleaning liquid W and the gas are separated by the eliminator 54, and the cleaning liquid W falls and is used for the next collection, and the gas is removed. Is discharged from the gas discharge part 34 to the outside of the tower 30.
[0040]
According to the experiment, in the ordinary dust collection, sufficient dust collection is achieved by dividing the tower 30 with two partition plates 40 and having three partial spaces including the lower partial space in which the washing liquid W is stored. It was confirmed that it was possible and required less power. When the diameter of the dust in the gas is extremely small or when the dust is difficult to get wet with the cleaning liquid W, the distance between the partition plates 40 and the partition plates 40 is reduced, or the number of the partition plates 40 is increased, and the number of partial spaces is increased. Satisfactory dust collection becomes possible by increasing. Further, it is not necessary to provide a so-called back filter on the downstream side after the separation of the cleaning liquid W and the gas. That is, since the dust collector can be designed according to the dust diameter and concentration in the gas, the nature of the dust, and the dust removal rate, the required dust and the production cost can be reduced.
[0041]
In the above embodiment, the injection port 51 of the injection nozzle 50 may be provided near the lower side of the narrow passage port 41. Further, it may be provided in the lowermost partial spaces Sa and Sb. Further, the number of the injection nozzles 50 is not limited to the above, and may be appropriately changed, for example, provided only in the uppermost partial space Se, or provided plurally for each of the partial spaces Sa, Sb, Sc, Sd, Se. I can do it. Further, the gas to be handled may be any gas generated in refuse incineration, various chemical operations and physical operations.
[0042]

First, the dust inside can be collected by the stored cleaning liquid, and at the same time, the gas flows at a high speed by passing through a narrow passage, and the cleaning liquid from the injection nozzle is formed into fine droplets by a high-speed gas flow, and the high-speed A gas containing droplets and dust collides with the upper partition plate to generate a vortex, thereby forming a fluidized bed.
