Description
Technical field
The utility model belongs to field of chemical equipment, relates to a kind of reaction unit, particularly relates to a kind of serialization ultralow temperature reaction unit.
Background technology
Organic phosphine class, boric acid compound are the important intermediates of a class in pharmacy, electronic chemical product, catalyst field, and most of reaction needed is reacted under the condition of ultralow temperature of-80 DEG C.At present, the low-temp reaction still that the 500L of employing band stirs more is in the industrial production produced, and the structure of reactor is: add coil pipe in still, passes into liquid nitrogen and lowers the temperature; Still outer jacketed is vacuum state in chuck.Due in course of reaction, air-teturning mixed phenomenon is serious, and temperature in the kettle is once higher than reaction temperature, and side reaction aggravates, and causes target product yield to reduce.In course of reaction, the temperature of charge near coil pipe is extremely low, and the temperature of charge away from coil pipe is higher, and cooling-down effect is poor.All need cleaning reaction owing to producing at every turn, again feed intake, drop to-80 DEG C from normal temperature repeatedly to reactor, production efficiency is low, and energy waste is extremely serious, and cost of labor remains high.For meeting industrial production demand, be badly in need of at present improving it.
Summary of the invention
Not enough for prior art, it is simple that the utility model object is to provide a kind of structure, consumes energy low, simple to operate, steady quality, operating efficiency is high, be particularly suitable for ultra low temperature state under continuous prodution organic phosphine class, boric acid series products device.
For realizing the purpose of this utility model, concrete technical scheme is as follows:
This reaction unit comprises low head and kettle.Its feature is: upper cover has man-hole opening, mirror mouth, noble gas import, charging aperture, is provided with static column plate in charging aperture pipeline, and charging aperture pipe end is connected with distributing device.Different liquid charging stocks enters pipeline by charging aperture, the static column plate in charging aperture pipeline mixes, by being delivered continuously in reactor after distributing device.Kettle is made up of tubulation, external jacket, thermo detector, and tubulation is vertically arranged in parallel, isometric with kettle, and the upper orifice of every root tubulation is corresponding with the circular hole that upper cover base plate distributes to be connected, and lower nozzle is corresponding with the circular hole on low head base plate to be connected.Fill solid catalyst or solid reaction raw material or solid inert filler in every root tubulation, bottom tubulation, install screen pack additional; Be full of liquid nitrogen between tubulation, thermo detector is positioned at the outer side of kettle, and one end is connected with tubulation outer wall; Be provided with vacuum jacket layer outside kettle, play protection heat-blocking action.Low head is provided with mirror mouth, Pressure gauge, inert gas outlet, discharging opening.Upper low head is with bolts with kettle respectively.
Described distributing device adopts gondola water faucet structure with holes, is evenly distributed in by liquid charging stock in reactor tube side.Thermo detector upper, middle and lower are uniformly distributed in the outer side of kettle, as point for measuring temperature observing and controlling temperature in the kettle at any time.
The utility model device innovative point and principle are: reaction raw materials is by charging aperture pipeline Homogeneous phase mixing, carried by gondola water faucet distributing device and flow into tubulation, load solid catalyst or solid material or solid inert filler in tubulation, liquid nitrogen is full of between tubulation outer wall, circulation is imported and exported by liquid nitrogen, reaction temperature can be regulated well, maintain low-temperature condition, under low-temperature condition, liquid charging stock at the uniform velocity down contacts with solid catalyst in tubulation or solid material in flow process in tubulation, gradual reaction in tubulation tube side, reacted material enters subsequent processing by discharging opening.
The invention has the beneficial effects as follows: adopt tubular structure in still, different material mixes in charging aperture, can continuity periodic duty, cold media uses the liquid nitrogen of-198 DEG C, and under tubulation is in protection of liquid nitrogen state, heat transfer efficiency is high, consumes energy extremely low; Fill solid catalyst or solid material or solid inert filler in tubulation, augmenting response contact area, because material is without air-teturning mixed phenomenon, avoids side reaction aggravate, and main reaction can be carried out preferably, thus the production yield that acquisition is higher.Organic phosphine class, boric acid series products is produced, steady quality, high, the applicable industrial application of operating efficiency under ultra low temperature state.
