4, the liquid distribution trough structure adopted is simple, process easy and result of use good, rectifying column reaction product is evenly distributed, stable.
5, the side line structure of reactor adopted is simple, process easy and result of use good, install lay convenient.
6, the upper column body structure of rectifying column tower body is simple, reasonable in design and input cost is lower, result of use is good, the top of top tower body is boundling rectifying section and its underpart is upper column plate laying section, be divided into multiple in the vertical boundling rectification zone to laying in boundling rectifying section, upper column plate is laid section and is communicated with by multiple described boundling rectification zone with between tower body top, top, and each boundling rectification zone is a small-bore rectifying column; Upper column plate to be laid in section by upper to being arranged with polylith column plate.Study discovery by analysis: traditional multitower saves single tower series rectification tower, tower effect is very low, for packed tower, the reason causing low tower to imitate is a lot, to be phegma form wall stream from the tower wall that tower section temperature is minimum to main cause, and the gas phase that rises of tower from tower intervening resistance minimum quickly through, gas-liquid exchange efficiency is very poor, although make many efforts on tower internals, eventually fail to obtain the breakthrough that the number of plates order of magnitude improves.
In boundling rectifying section of the present invention, multiple small-bore rectifying column is in parallel, achieve boundling rectifying, the principle of boundling rectifying is as follows: because packed tower is from the mass transfer apparatus of the filler in tower as gas-liquid two-phase Contact component, liquid sprays filler from tower top through liquid distribution trough, and flows down along filling surface; At the bottom of tower, uprising gas and liquid are the space that adverse current continues through packing layer, and on filling surface, gas-liquid two-phase close contact carries out mass transfer; Like this, two phase compositions are along tower height consecutive variations, and under normal operating condition, gas phase is continuous phase, and liquid phase is decentralized photo.
During actual use, when liquid flows downward along packing layer, have gradually to the trend that tower wall is concentrated, near making tower wall, flow quantity increases gradually, and this phenomenon is called wall stream.Wall stream effect causes gas-liquid two-phase skewness in packing layer, thus mass-transfer efficiency is declined, and especially when packing layer is higher, tower diameter is larger, rectification efficiency meeting degradation, even loses separating effect.Adopt in boundling rectifying section of the present invention and forms a major diameter rectifying column by multiple small-bore rectifying column parallel connection and replace single straight through tower greatly, inner-tower filling material diameter is reduced, avoids wall stream and be inclined to, thus the separative efficiency of tower is significantly improved.
Boundling rectifying has following characteristics: mass-transfer efficiency is high, equipment volume is little, and the time of staying is short, and liquid holdup is changeable, anti-stifled ability is strong, operating parameter elasticity is large, easy to maintenance, is applicable to the difficult material, heat sensitive material, high-viscosity material etc. that are separated, also solve lab scale poor in advance to the calculating of industry amplification, boundling rectifying can be accomplished substantially, and during lab scale, tower height is how many, amplifies tower height after producing and is still how many.Therefore after industrial rectifying adopts this new technology, the effect highly significants such as the saving equipment brought and rapidoprint, investment reduction, reduction investment risk, reduction per Unit GDP Energy Consumption, minimizing land resource.
Boundling rectifying is grafted directly to laboratory in industrial production without the trourelle of wall stream, gas-liquid total exchange through high-efficient spiral-screen column, the corresponding expanding requirement brought because tower reactor strengthens is amplified for overcoming industry, the mode of boundling parallel connection is adopted to solve, so both ensure that the high tray-number of the small-bore tower in laboratory, prevent again because of industry amplify tower diameter bring tower effect loss, thus avoid with tower height mend tower imitate traditional rectifying pattern.The tower effect of small-bore rectifying column in parallel is imitated with traditional heavy caliber rectifying tower and is differed multiple order of magnitude, and that is for the heavy caliber rectifying column of former 10 meters high, the tower body height of boundling rectifying only needs 1 meter; For the heavy caliber column in series of tradition 20 meters high, the tower body height of boundling rectifying only needs 2 meters, and remaining person analogizes.Because tower height becomes the order of magnitude to decline, the operating temperature of tower reactor also declines to some extent, thus boundling Finestill energy-saving successful.
7, overall construction design is reasonable, the top of rectifying column tower body is divided into boundling rectifying section and is positioned at below boundling rectifying section and section laid by the upper column plate being provided with polylith column plate from top to bottom, rectifying column tower body bottom is lay section by the upper lower column plate to being arranged with polylith column plate, during actual use, multiple column plate can ensure that gas-liquid two-phase effectively contacts, and obtains good mass transfer effect.And be provided with multiple packing section from top to bottom between upper column plate laying section and lower column plate laying section, a packed bed is provided with in each packing section, the catch tray that this packed bed comprises packing layer, is positioned at the liquid distribution trough directly over packing layer and is positioned at immediately below packing layer, the liquid distribution trough inside that in neighbouring two packing section, in superposed upper packing section, the catch tray filled and the lower packing section being positioned at bottom fill is communicated with and the two forms liquid collection and redistributor; Simultaneously, the installation position of multiple side line reactor respectively with the installation position one_to_one corresponding of multiple packing section, and multiple side line reactor communicates with multiple packing section inside respectively, thus reaction of high order and multi-stage separation treatment can be carried out to product, thus can increase substantially reaction conversion ratio and product yield.When adopting the present invention to produce polymethoxy dimethyl ether, can effectively improve polymethoxy dimethyl ether (PODE
3-8) reaction conversion ratio and product yield, in side line reactor, used catalyst is modified cation-exchange resin is catalyst, makes the yield of polymethoxy dimethyl ether reach 95%, wherein polymethoxy dimethyl ether (the PODE of n=3-8
3-8) product can reach 80% ~ 95%.To sum up, rectifying column tower body is divided into boundling rectifying section (i.e. boundling rectifying section), extraction section (namely go up column plate lay section), reaction zone (i.e. multiple packing section and each packing section inside communicate multiple side line reactors) and air lift district (namely descending column plate laying section) from top to bottom by the present invention, thus can effectively provide reaction conversion ratio and product yield.
8, result of use is good and practical value is high, can effectively improve reaction conversion ratio and product yield, and industrialization degree is higher simultaneously, and raw material availability is higher, and production cost is lower.
