Abstract
A strike flow reactor of vertical circulation pertains to a technical device of chemical reaction. The reactor can create good micromixing and is adaptable to the need of mass reaction systems. The basic elements include a cylindrical container 1 whose upside keeps gas phase space, an upper guide canister and a lower guide canister 2 which are arranged in the container 1 and immerged below the craft medium, and two propellers 3, 4 whose spiral directions are opposite and which are arranged in the upper and lower guide canisters. The two propellers 3, 4 push liquid to circulate and flow through the guide canisters respectively up and down and impact each other vis-a-vis in the middle part of the container 1, thus promoting the mixing and alternated contact. The reactor can intermittently, semicontinuously and continuously process the operation of pressurization and decompression, can randomly set up a detention time and can exchange heat. The reactor applies to the multiphase reaction process of liquid phase or continuity by liquid phase. The cylindrical design makes the forced condition of the container warm and deep and easy to be designed and made into a device which can work under the forced condition.
Description
The utility model is called " vertical circulation impact flow reactor ", belongs to the chemical reaction technical equipment.
For reaction of carrying out in liquid phase and liquid-solid phase system and processes such as reaction-precipitation and crystallization, the mixing on the troubled water in the reactor, the especially molecular scale is that microcosmic is mixed with material impact.The industrial conventional apparatus that is widely used in this class process is stirred tank reactor (brief note is STR).This reactor relies on the single or multiple lift paddle that rotates to drive fluid and rotatablely moves normally in a height and diameter container about equally, makes between the stream group and produces relative motion between the liquid-solid phase, thereby mix.Because relative motion is violent inadequately between the stream group that this mode produces and between liquid-solid phase, mix, especially the microcosmic troubled water is undesirable, thereby the said process efficient of carrying out in liquid phase and the liquid-solid phase is not high enough; Simultaneously, the centrifugal force that rotation causes makes most of the consumption at fluid and wall of the mechanical energy of paddle input collide, and capacity usage ratio is not high yet.Wu Yuan has researched and developed a kind of " submergence circulation impact flow reactor ", and (ZL00230326.4) patents.This reactor has following key property and advantage: the special fluidal texture of (1) complete mixing flow-no mixed flow series circulation; (2) the percussion flow microcosmic mixes strong; (3) by the arrangement of circulation, can be set the reaction time as required arbitrarily, adapt to the requirement of most of reaction systems; (4) can be intermittently, also can continued operation; (5) can provide heat transfer boundary condition.It has demonstrated superior performance in producing application such as superfine powder; Also has the low advantage of power consumption.Yet also there is certain limitation in this reactor aspect commercial Application.Subject matter is that the sidewall of reactor shape has sizable a part of plane, and stressing conditions is relatively harsher.When being used for the process of carrying out under pressurization or vacuum, wall certainly will be done very thickly, increases weight of equipment, material consumption and investment greatly.
The purpose of this utility model is to overcome above-mentioned deficiency, by changing structure, a kind of advantage and performance that can keep submergence circulation impact flow reactor being provided, is convenient to design and manufacture the reaction technology equipment that can work again under the pressurized condition.
Fig. 1 is the structural representation of the vertical circulation impact flow reactor of the utility model.
Below in conjunction with accompanying drawing, content of the present utility model and implementation method are described.
The basic element of character of the present utility model comprises cylindrical pressure vessel 1, vertical coaxially be installed in upper and lower two guide shells 2 in the container 1 and be installed in last screw 3 and following screw 4 in two guide shells coaxially respectively, their hand of spiral is opposite, promptly one left-handed, another dextrorotation.Adorn processing medium in the container 1, liquid level the guide shell of not going up, and constituted the dischargeable capacity district of reaction or other process; Its top remains gas-phase space, to adapt to the requirement of most of reaction systems.For improving flow efficiency, preventing the dead angle, hemispherical can be made in container 1 bottom.Two screws 3 and 4 propelling fluids (processing medium) flow to container 1 middle part from the upper and lower through guide shell 2 respectively, and at this place bump in opposite directions, around striking face, form impingement region IZ.In this district from relative motion violent between the stream of different directions group make between stream group with liquid-solid phase between mix effectively and contact chemical reaction or other process that promotion is wherein carried out.Behind the bump, fluid returns the two ends up and down of container 1 respectively through guide shell 2 up and down and the ring casing between container 1 inwall, is carried by guide shell 2 up and down by screw 3 and 4 respectively again then to flow to container 1 middle part and bump once more, circulates so repeatedly.
Reactor of the present utility model can intermittently operated, also can continued operation.During intermittently operated, an amount of a collection of adding container 1 of reaction mass; After the process certain hour was finished reaction, material drew off by bottom vomit pipe 5.Raw material liq or suspended substance add reactor continuously by its top feed pipe 6 during continued operation, flow out continuously by sidewall discharge nozzle 7 through the material that reacts; By controlling suitable feed rate, mean residence time can be set arbitrarily.Can also operate by semi-batch (semicontinuous), promptly one or more reactants once add earlier reactor, and another kind of or several reactants then limit border ring add by feed pipe 6; Whole materials drew off by bottom discharge pipe 5 after question response was finished.If there is gas to produce, can discharge in the course of reaction by top blast pipe 11.
Reactor wall of the present utility model is provided with heat exchange jacket 10 outward, can during reaction heat or the process for cooling medium.Take over 8 by the bottom during cooling and feed cold water or other cooling medium, take over 9 through top after the heat exchange and discharge; It is opposite when the turnover pipe of heat medium is with cooling when needing heating.In case of necessity, can also arrange coiled pipe heat exchange (not drawing among the figure) outside the guide shell 2.
Reactor of the present utility model is provided with top cover 12.By to container 1 and top cover 12 mechanical strengths and the suitable design of connecting mode between them, this reactor is applicable to operating under pressurization or vacuum.For the uncovered process of carrying out of needs, top cover 12 can be cancelled.
The vertical circulation impact flow reactor of the utility model has traditional stirred tank reactor can be provided with mean residence time, airtight, pressurization or vacuum, heating or cooling, continuously or all functions such as intermittently operated arbitrarily; Also kept the microcosmic of submergence circulation impact flow reactor to mix characteristics such as strong and special fluidal texture.In addition, because the reaction vessel body changes cylinder type into, force-bearing situation is gentle and kind, designs and manufacture the equipment of working under the pressurized condition easily, has overcome submergence circulation impact flow reactor limitation in this respect.Compare with submergence circulation impact flow reactor, the utility model also has the advantage of two propeller coaxials, a shared drive motors, makes the operation of device more convenient to a certain extent.
