【発明に属する技術分野】
この発明は、重油を燃料とするディーゼル機関の入口に配置される従来の複式燃料油逆洗コシ器に周波数100KHz近傍の超音波装置を組み込み、コシ器の通油抵抗が設定差圧値以上に上昇した場合に超音波装置が作動し、
コシ網に付着したスラッジ分を粉砕、除去して、通油抵抗を正常に戻す機能をもたせた超音波スラッジ粉砕燃料油コシ器に関するものである。
【0002】
【従来の技術】
従来、重油の清浄系統には遠心分離機によりスラッジ分を除去したのち、または、重油を一旦ミキサー又はホモジナイザー等で攪拌、粉砕したのちこの燃料油コシ器で不純物を除去していた。
【0003】
【発明が解決しようとする課題】
これには次のような欠点があった。
(イ)スラッジは石油精製過程で混入したアルミナ、シリカ、カーボン等の固形分と、その後、燃料タンク貯蔵、加熱中に析出するワックス、アスファルテン成分が凝集し、これらの固形分を被覆増殖するため燃料油との比重差が無くなり、遠心分離機によるスラッジの除去が不十分のまま燃料コシ器に送り込まれるため、必然的にコシ網の目詰りを早めた。
(ロ)通油中にコシ網に付着したスラッジは逆流洗浄工程でコシ網より除去されて器外に排出されるため、これを被覆または凝集したワックス、アスファルテン成分は廃油として処理されたので不経済であった。
(ハ)コシ網(40〜50ミクロン精度)に一旦固着した微小固形分は逆流洗浄工程でも除去困難となり、これを除去するにはコシ網を取り出し、化学洗浄を必要とした。
(二)燃料油をミキサーまたはホモジナイザーを使用してスラッジを粉砕する場合でも、凝集してスラッジ化したワックス、アスハルテンは燃料油に十分には溶解出来ずにコシ網に付着した。
本発明は、以上の点を解決するためのものである。
【0004】
【課題を解決するための手段】
従来の複式燃料油コシ器の内部中央に超音波振動子(1)と、この超音波をコシ網の内面方向に反射させる円錐形上部,下部反射板(2)(3)とをセットにして(コシ器の寸法が大きい場合は複数組)を1本の中空軸(4)に取り付け、超音波を起動させるコシ器の差圧発信器(6)を設ける。
本発明は,以上の構成よりなる超音波スラッジ粉砕燃料油コシ器である。
【0005】
【発明の実施の形態】
以下、本発明の実施の形態について説明する。
従来の複式油コシ(日本工業規格F−7202)の形状、または此れに類似した形状をもつ複式燃料油逆洗コシ器(9)のコシ網(10)の中央に、超音波100KHz近傍の周波数と共振する市販の、音圧強度50W/cm相当(外径約80mm)の円板形圧電振動子(1)と、この振動子の外径寸法とほぼ同じ外径の円錐形上部下部反射板(2)(3)を振動子を間に挟んで中空軸(4)に取付ける。
反射板(2)(3)の位置は超音波反射方向(14)がコシ網内面に照射出来る様に配置する。又この材料は銅材を使用して超音波の非透過性をもたせる。振動子(1)の電極リード線(5)は中空軸(4)の中空部を通して外部の超音波発信器(7)に配線する。
コシ器の出入口差圧発信器(6)、1号2号コシ器切り換え電磁弁(11)、ドレン電磁弁(12)と、これらの作動を時間的に制御する60秒タイマー付制御盤(8)をコシ器(9)の外部に設ける。
本発明は以上のような構成からなり、これが使用されるときは、
通油によりコシ器(9)の出入口差圧が所定の差圧制限値に達すると差圧発信器(6)により制御盤(8)を介して超音波発信器(7)および制御盤内のタイマーが作動して振動子(1)の上面、下面より超音波を放射する。
放射された超音波は上部、下部反射板(2)(3)でコシ網内面を照射しながら、先ず、約20秒間は付着したスラッジの粒子を超音波加速度により粉砕し、ワックス、アスファルテン成分は燃料油に溶解させ、コシ網(10)で漉されて、清浄油としてエンジンに送られる。
次ぎの10秒間では、先ず、コシ器切換え電動弁(11)及びドレン電磁弁(12)が作動し、通油中の1号コシ器入口を遮断し、切り替えられた2号コシ器の通油圧により、1号コシ器のコシ網に付着、固着した残留スラッジは逆流洗浄により除去され、絞り弁(13)を経て器外に排出される。
この逆洗工程の完了でドレン電磁弁(12)が閉弁して超音波が停止する。
【0006】
【発明の効果】
タンク貯蔵中にスラッジ化したワックス,アスファルテン成分は通油中に燃料油に溶解し、逆洗行程で排出されたドレンは別置きドレンタンクのコシ網で固形分だけが除去され、残りは燃料油として回収されるので、次のような効果をもたらす。
(ア)省エネ効果を有する。
(イ)スラッジの陸揚げ処理費を削減する。
(ウ)コシ網を化学洗浄する必要がなく、省力化をもたらす。
(エ)音圧パワーは約50W/cm程度で且つ作動がスラッジ排出工程だけであるので省電力化となる。
(オ)超音波発生装置の構造が非常に簡単である。

TECHNICAL FIELD OF THE INVENTION
The present invention incorporates an ultrasonic device having a frequency of about 100 KHz into a conventional double fuel oil backwashing stiffener arranged at the entrance of a diesel engine using heavy oil as a fuel, and the oil passing resistance of the stiffener becomes equal to or higher than a set differential pressure value. When it rises, the ultrasonic device is activated,
The present invention relates to an ultrasonic sludge pulverized fuel oil stiffener having a function of pulverizing and removing sludge adhering to a koshi net to restore oil flow resistance to normal.
[0002]
[Prior art]
Conventionally, in a heavy oil cleaning system, after removing sludge by a centrifugal separator, or once stirring and pulverizing heavy oil with a mixer or a homogenizer or the like, impurities have been removed with this fuel oil stiffener.
[0003]
[Problems to be solved by the invention]
This had the following disadvantages.
(A) Sludge is used to solidify the solids such as alumina, silica, and carbon mixed in the oil refining process, and the wax and asphaltene components that precipitate during storage and heating of the fuel tank. The difference in specific gravity from fuel oil disappeared, and the sludge was not sufficiently removed by the centrifugal separator.
(B) Sludge adhering to the stiffener net during the oil passing is removed from the stiffener net in the backwashing process and discharged outside the vessel. The wax or asphalten component covering or coagulating the sludge is treated as waste oil, so it is unreasonable. It was economic.
(C) The fine solids that once adhered to the stiffener (accuracy of 40 to 50 microns) became difficult to remove even in the backwashing step. To remove the stiffness, the stiffener was taken out and chemical cleaning was required.
(2) Even when the fuel oil was pulverized into sludge using a mixer or a homogenizer, the coagulated sludge wax and asharten were not sufficiently dissolved in the fuel oil and adhered to the koshi net.
The present invention is to solve the above points.
[0004]
[Means for Solving the Problems]
An ultrasonic vibrator (1) is provided in the center of the inside of a conventional dual fuel oil stiffener, and conical upper and lower reflectors (2) and (3) for reflecting the ultrasonic waves toward the inner surface of the stiffener net are set. A plurality of sets (when the size of the stiffener is large) are attached to one hollow shaft (4), and a stiffener differential pressure transmitter (6) for activating ultrasonic waves is provided.
The present invention is an ultrasonic sludge pulverized fuel oil stiffener having the above configuration.
[0005]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described.
In the center of a stiffness net (10) of a double fuel oil backwash stiffener (9) having a shape of a conventional double oil stiffness (Japanese Industrial Standard F-7202) or a shape similar thereto, an ultrasonic wave near 100 KHz is provided. A commercially available disk-shaped piezoelectric vibrator (1) having a sound pressure intensity equivalent to 50 W / cm 2 (outer diameter of about 80 mm) that resonates with the frequency, and a conical upper and lower part having an outer diameter almost the same as the outer diameter of the vibrator The reflectors (2) and (3) are attached to the hollow shaft (4) with the vibrator interposed therebetween.
The positions of the reflectors (2) and (3) are arranged so that the ultrasonic wave reflection direction (14) can be applied to the inner surface of the elastic net. Also, this material is made of a copper material so as to have an ultrasonic impermeability. The electrode lead wire (5) of the vibrator (1) is wired to the external ultrasonic transmitter (7) through the hollow portion of the hollow shaft (4).
A differential pressure transmitter (6), a No. 1 and No. 2 stiffener switching solenoid valve (11) and a drain solenoid valve (12) for a stiffener, and a control panel with a 60-second timer (8) for temporally controlling the operation of these. ) Is provided outside the stiffener (9).
The present invention has the above configuration, and when this is used,
When the inlet / outlet differential pressure of the stiffener (9) reaches a predetermined differential pressure limit value due to oil flow, the ultrasonic transmitter (7) and the control panel are controlled by the differential pressure transmitter (6) via the control panel (8). The timer operates to emit ultrasonic waves from the upper and lower surfaces of the vibrator (1).
The radiated ultrasonic waves irradiate the inner surface of the stiff mesh with the upper and lower reflectors (2) and (3), and firstly, the sludge particles adhered are crushed by ultrasonic acceleration for about 20 seconds, and the wax and asphaltene components are removed. It is dissolved in fuel oil, filtered through a koshi net (10), and sent to the engine as clean oil.
In the next 10 seconds, first, the stiffener switching electric valve (11) and the drain solenoid valve (12) are operated to shut off the No. 1 stiffener inlet during oil flow, and to switch the hydraulic pressure of the switched second stiffener. As a result, the residual sludge adhering and sticking to the stiffness net of the No. 1 stiffener is removed by backwashing, and discharged out of the stiffener through the throttle valve (13).
Upon completion of this backwashing step, the drain solenoid valve (12) closes and the ultrasonic wave stops.
[0006]
【The invention's effect】
The wax and asphaltene components sludged during storage in the tank are dissolved in the fuel oil during the passage of oil, and the drain discharged in the backwashing process is removed only by the solid net in the separate drain tank, and the remainder is fuel oil The following effects are obtained.
(A) It has an energy saving effect.
(B) Reduce the disposal cost of sludge.
(C) There is no need to chemically clean the koshi net, resulting in labor saving.
(D) Since the sound pressure power is about 50 W / cm 2 and the operation is only the sludge discharging step, power is saved.
(E) The structure of the ultrasonic generator is very simple.
