工業(yè)光化學(xué)為了什么?
WHY INDUSTRIAL PHOTOCHEMISTRY?
為了加快反應(yīng)從而提高生產(chǎn)效率,大量的化學(xué)反應(yīng)是在 100 ~ 250 °C進(jìn)行, 可是在這樣的溫度下, 分解過(guò)程已經(jīng)開(kāi)始, 由此引起產(chǎn)率的損失和產(chǎn)生副產(chǎn)品。
A large number of chemical reactions are carried out at temperatures between 100 and 250 °C in order to achieve a fast reaction and thus high productivity. At these temperatures, however, decomposition processes already start with corresponding losses in yield and undesired by-products.
在催化劑的幫助下, 即使在較低的溫度下也能起動(dòng)反應(yīng), 但運(yùn)行成本比較高。
With the help of catalysts, reactions can be activated even at lower temperatures, but are expensive to procure and to handle.
光化學(xué)提供了另一種漂亮的替代方法,并允許新的合成。 不用熱和催化劑, 而是用光能觸發(fā)反應(yīng),這樣的反應(yīng)通常在低于100 °C, 時(shí)常甚至在常溫條件下進(jìn)行, 采用這種工藝, 分解反應(yīng)或副產(chǎn)品的產(chǎn)生可降至或根本不產(chǎn)生。
Photochemistry offers an elegant alternative and allows new syntheses. Not heat or catalysts, but the energy of light activates the reaction, which can then take place at temperatures well below 100 °C and often even at room temperature. By this process, decomposition or by-products are reduced to a minimum or do not arise at all.
采用光而不是熱,這種原理可用于很多種產(chǎn)品的合成, 如:氯化、磺化、磺化氧化或亞硝基化
Light instead of heat, this principle can be applied to a variety of syntheses such as chlorinations, sulfonations, sulfoxidations or nitrosylations.
EKATO光反應(yīng)器交鑰匙工程
THE TURNKEY EKATO-PHOTOREACTOR
EKATO帶攪拌的光反應(yīng)器由光能觸發(fā)合成反應(yīng), *的攪拌技術(shù)確保反應(yīng)器內(nèi)很高的循環(huán)量。 這種新的攪拌反應(yīng)器的概念對(duì)于含有液體、氣體和固體的多相反應(yīng)是相當(dāng)理想的。這種反應(yīng)器的光源浸入在液體中, 操作安全, 兼顧了高效和靈活性。反應(yīng)器容積至50 m3的設(shè)計(jì)已經(jīng)過(guò)實(shí)際驗(yàn)證, 我們的專家還可以作進(jìn)一步的安全放大。
The stirred photoreactor from EKATO allows syntheses by the energy of light and an advanced stirring technique which ensures high circulation rates in the reactor. The concept of this new stirred reactor is ideal for multiphase reactions involving liquids, gases and solids. It combines high productivity and flexibility with the safe operation of immersed light sources. Reactors up to 50 m3 are realized with this proven design and a safe scale-up by our specialists enables further reactor sizes.
紫外線光源 - 安全操作
The UV light sources - safe operation
光源是經(jīng)ATEX安全認(rèn)證的水銀蒸汽或LED燈組件, 這光源是由我們的合作方 Peschl Ultraviolet GmbH (工業(yè)領(lǐng)域紫外光源專家)提供。
The light sources are ATEX-certified mercury vapor or LED lamp modules, which we obtain via our cooperation partner, Peschl Ultraviolet GmbH (the global expert in the field of industrial UV light sources).
紫外光源組件安裝在有保護(hù)作用的石英玻璃管內(nèi), 石英玻璃管由容器頂上的管口插入, 通過(guò)上面的管口與電源和冷卻系統(tǒng)相連。 浸入液體的紫外燈泡的功率有5~60 kW, 因此玻璃管內(nèi)需要冷卻, 不然光源會(huì)由于表面高溫而損壞。 工業(yè)上使用的光反應(yīng)器通常配備有4~20根這樣的玻璃管。
The UV light modules are housed in protection tubes made of quartz glass, which are inserted through nozzles in the top of the vessel, where they are also connected to the power supply and the cooling system. These UV immersion lamps have a power of 5 - 60 kW. Therefore, a cooling within the glass tube is required, otherwise the sensitive molecules can be damaged by high surface temperatures. Industrial reactors are equipped with 4 to 20 of such glass tubes.
安裝有光源的玻璃管在帶攪拌的容器中將經(jīng)受流體力和熱應(yīng)力,這種條件下, 將紫外燈穩(wěn)妥地安裝進(jìn)反應(yīng)器中, 是一個(gè)特別的挑戰(zhàn)。
The glass tubes with their light sources are exposed to hydraulic and thermal loads in the stirred vessel. A particular challenge in this case is secure mounting of the UV immersion lamps on the reactor.
EKATO開(kāi)發(fā)了特殊的固定裝置,并取得,該裝置確保容器內(nèi)的元器件在任務(wù)操作條件下不出現(xiàn)超過(guò)允許的應(yīng)力和振動(dòng)。即使最不可能發(fā)生的象玻璃管泄漏這種情況, 危險(xiǎn)的物料馬上被檢測(cè)到, 且不會(huì)通過(guò)電或冷卻通道流出容器。 在EKATO技術(shù)中心,這些設(shè)計(jì)的可靠性經(jīng)受了各種的測(cè)試, 并在許多項(xiàng)目中得到了充分的驗(yàn)證。
Special holders developed and patented by EKATO to ensure that in any operating condition impermissible stresses or vibrations will not occur in the component. Dangerous reactants are detected immediately even in the unlikely event of a glass breakage and do not reach the outside via the electrical connections or the cooling. In EKATO’s technical center the reliability of these designs was investigated by tests and it has been comprehensively confirmed in numerous operational assignments.
攪拌系統(tǒng) - 需要高的循環(huán)速率
THE AGITATOR SYSTEM - HIGH CIRCULATION RATES REQUIRED
紫外線輻射只有輕度地穿透進(jìn)物料, 所以這種反應(yīng)器的攪拌混合系統(tǒng)是單別設(shè)計(jì)的,可以確保大的循環(huán)量, 從而保證反應(yīng)物料流動(dòng)經(jīng)過(guò)光源的情況。
The UV radiation penetrates only slightly into the product. The mixing system is individually tailored to the reactions and ensures through the high circulation rates that the reactants are optimally transported to the light sources.
EKATO組合加氣槳葉系統(tǒng), 帶有自吸式渦輪槳, 用于加氣的應(yīng)用, 如氯化工藝。 氣體的反應(yīng)物如Cl2, O2 或 SO2被高效地分散在液體中, 從而達(dá)到的傳質(zhì)以實(shí)現(xiàn)高的時(shí)空產(chǎn)量。
The EKATO Combined Gassing System with its self-priming turbine is used for gassed application such as chlorination processes. Gaseous reactants such as Cl2, O2 or SO2 are efficiently dispersed to achieve maximum mass transfer for high space-time yields.
固體的均勻分散(如聚合物)和反應(yīng)器內(nèi)熱量的擴(kuò)散也是反應(yīng)器和攪拌機(jī)設(shè)計(jì)中的一個(gè)重要的挑戰(zhàn), EKATO光反應(yīng)器地解決了這些技術(shù)問(wèn)題。
The homogeneous distribution of solids (e.g. Polymers) and the dissipation of the heat of reaction are also an important challenge when designing the vessel and agitator. This is optimally solved by the EKATO photoreactor.
當(dāng)使用危險(xiǎn)品物料(如氯氣) 時(shí), 密封和安全的問(wèn)題是優(yōu)先級(jí)的, 這是需要重點(diǎn)關(guān)注的大局問(wèn)題。
When using hazardous substances, e.g. Chlorine gas, questions about the sealing and safety concept are at the top of the list of priorities. It is important to keep an eye on the big picture.
攪拌機(jī)軸與大氣環(huán)境間的密封是一個(gè)操作安全的關(guān)鍵點(diǎn)。 EKATO采用自己生產(chǎn)制造的特殊的雙端面或三端面機(jī)械密封, 或磁力驅(qū)動(dòng)。
The sealing of the agitator shaft to the atmosphere is a key element for operational safety. EKATO uses special double-acting or triple-acting mechanical seals or even magnetic drives from our own production.
EKATO光化學(xué)反應(yīng)器可以由多種材料制造, 常用的材料有:鋼涂陶瓷、不銹鋼、鎳基材料或鈦
EKATO photoreactors can be manufactured from numerous material variants. Common materials are: enameled steel, stainless steels, Ni-base materials or titanium.
