Description
本考案はメッキ廃液処理の分野に属し、具体的にはメッキ廃液の混合処理装置に関する。 The present invention belongs to the field of plating waste liquid treatment, and specifically relates to a mixing treatment apparatus for plating waste liquid.
物質移動は化学反応における不可欠なプロセスであり、物質移動の良否は化学反応の効率に直接影響を及ぼす。メッキ廃液分野において、物理化学的処理部で化学反応に主に慣用されている反応装置は機械的撹拌機を配設した廃液処理槽である。通常の機械的撹拌では、撹拌速度が低く、メッキ廃液の物理化学的処理部による物質移動の効果が悪いため、槽体の容積増加、反応滞留時間の延長でしか所期の混合効果を達成できない。しかし、槽体の容積増加によって槽体の敷地面積が増大し、それに加えて、反応槽体の移動が困難であることから、明らかに敷地面積が限られている一部の業者に不便をもたらす。 Mass transfer is an indispensable process in a chemical reaction, and the quality of mass transfer directly affects the efficiency of the chemical reaction. In the field of plating waste liquid, the reactor mainly used for chemical reactions in the physicochemical treatment unit is a waste liquid treatment tank provided with a mechanical stirrer. In normal mechanical stirring, the stirring speed is low and the effect of mass transfer by the physicochemical treatment section of the plating waste liquid is poor, so the desired mixing effect can only be achieved by increasing the volume of the tank and extending the reaction residence time. .. However, the increase in the volume of the tank body increases the site area of the tank body, and in addition, it is difficult to move the reaction tank body, which causes inconvenience to some contractors whose site area is clearly limited. ..
高効率な混合設備であるスタティックミキサは、従来の撹拌器と異なり、その内部に運動部材がなく、その動作メカニズムは、管路内に固定される特殊な構造部材で流体の管路内での流動状態を変更することで、二種以上の流体間の分散および混合という目的を達成する。他の設備に比べ、スタティックミキサは、効率が高く、体積が小さく、エネルギー消費が少なく、無駄な投資が省け、連続生産を実現しやすいなどの利点を有し、混合プロセスのみならず、気気混合、液液抽出、気液反応、伝熱促進および液液反応などを含むプロセスに用いることもできる。しかしながら、一般的なスタティックミキサは供給位置に制約があるため、二種以上の流体の流量が近くまたは流量の差が小さい稼働条件にしか適用できず、廃液処理業界としては、薬剤の使用量が廃液の質量の０．０１％〜１％であり、同時に、原料供給においても、二つの流体の流量の大きな差により混合が不均一になり、混合の効果に影響を及ぼす。 Unlike conventional stirrers, static mixers, which are highly efficient mixing equipment, do not have moving members inside, and their operating mechanism is a special structural member that is fixed in the pipeline and in the fluid pipeline. By changing the flow state, the purpose of dispersion and mixing between two or more kinds of fluids is achieved. Compared to other equipment, static mixers have advantages such as high efficiency, small volume, low energy consumption, unnecessary investment, and easy realization of continuous production. It can also be used in processes including mixing, liquid-liquid extraction, gas-liquid reaction, heat transfer promotion and liquid-liquid reaction. However, since a general static mixer has a limited supply position, it can be applied only to operating conditions where the flow rates of two or more kinds of fluids are close or the difference in flow rate is small, and the amount of chemicals used is large for the waste liquid treatment industry. It is 0.01% to 1% of the mass of the waste liquid, and at the same time, even in the raw material supply, the mixing becomes non-uniform due to the large difference in the flow rates of the two fluids, which affects the effect of the mixing.
本考案の目的はメッキ廃液の混合処理装置を提供することであり、段階的に供給し、混合液を部分的に還流させる方法で、従来のスタティックミキサの異なる流体の流量の大きな差により混合が不均一になり、混合の効果に影響を及ぼすという問題を効果的に回避でき、混合効率が向上し、同時に、従来の機械的撹拌機を配設した混合槽を用いた処理方法よりも優れ、応用上の価値が高い。 An object of the present invention is to provide a mixing treatment apparatus for plating waste liquid, which is a method of supplying the mixed liquid in stages and partially refluxing the mixed liquid, in which mixing is performed due to a large difference in the flow rates of different fluids of a conventional static mixer. The problem of non-uniformity and affecting the effect of mixing can be effectively avoided, the mixing efficiency is improved, and at the same time, it is superior to the processing method using a mixing tank equipped with a conventional mechanical stirrer. High application value.

従来技術に比べ、本考案は以下の有益な効果を有する。 Compared with the prior art, the present invention has the following beneficial effects.
本考案はスタティックミキサのもとに改良を行ったものであり、段階的に供給し、混合液を部分的に還流させる方法を用い、かつ角管の内部に「八」字形の通路を成すように第一液仕切り板を設け、「人」字形の液仕切り板を成すように第二液仕切り板を設けており、「八」字形の通路で流体が混合され、その速度が高められ、流体に背向する「人」字形の液仕切り板によって、流体が分けられて双方向のスパイラル還流が生じる。本考案の混合処理装置は、従来のスタティックミキサの異なる流体の流量の大きな差により混合が不均一になり、混合の効果に影響を及ぼすという問題を効果的に回避でき、混合効率が向上し、連続化のレベルが向上する。同時に、「八」字形の通路、「人」字形の液仕切り板を構成する液仕切り板は、いずれも角管両側の管壁と接続されず、それによって死角の形成、固体沈着物の発生、設備の汚れによる詰まりの発生が回避される。本考案の混合処理装置は従来の機械的な撹拌混合手段を代替でき、メッキ廃液処理業界の物理化学的処理部、特に流量差が大きな二つ以上の原料を同時に供給する場合に適する。 The present invention has been improved based on a static mixer, and uses a method of supplying the mixture in stages, partially recirculating the mixture, and forming an "eight" -shaped passage inside the square tube. The first liquid partition plate is provided in the above, and the second liquid partition plate is provided so as to form a "human" -shaped liquid partition plate. A "human" shaped liquid divider facing back separates the fluid and creates a bidirectional spiral return.

In the operation step of performing the mixing process using the mixing treatment device for the plating waste liquid of this embodiment, the plating waste liquid is continuously pumped into the mixing treatment device by the hydraulic feed pump, and the chemicals are continuously pumped into the mixing treatment device by the hydraulic feed pump according to the set flow rate. The fluid is gradually supplied from the drug inlet 4 into the mixing treatment device, and after the fluid flows into the mixing treatment device, it is made to flow into the "eight" -shaped passage from the open end to increase the flow velocity in the passage, and "human". A high-speed impact on a "shaped liquid divider" separates the fluid, causing bidirectional spiral recirculation, and controlling the mixture to partially recirculate during mixing, further improving the effectiveness of the mixing. Including that. The mixed liquid is finally discharged from the mixed
