Description
Technical field
The utility model relates to a kind of novel Liquid-phase reactor, be applicable to that mainly liquid-liquid phase, solution-air phase, solid-liquid phase compound react, can in fine chemistry industry and specialty chemicals industry, (comprise fields such as medicine intermediate, agricultural chemicals, biochemical industry, catalyst, various additive, auxiliary agent, coating, dyestuff, reagent, oil field chemical, electronics and photochemistry product) and be extensive use of.
Background technology
There is family more than 20,000 in the enterprise of China's fine chemistry industry and specialty chemicals industry at present, and annual total output reaches about 3,000 ten thousand tons, about 2 trillion yuan of the annual gross output value.China's fine chemistry industry and special-purpose chemical products are produced more than 30,000 kind approximately, because kind is few, have many product qualities low, do not satisfy domestic demand, and annual import volume is also bigger; Small enterprise is many in addition, equipment is little, quality is unstable, energy consumption is high, bigger, the many technological element of a product of pollution are low, competitiveness is lower.
Existing more than 20,000 tame fine chemistry industries of China and specialty chemicals enterprise produce fine chemical product and be unable to do without Liquid-phase reactor (still), a large amount of Liquid-phase reactor are arranged in use in the fine chemistry industry industry.In the production process of fine chemical product, in order to react on request, always require reaction mass even contact and reacting as early as possible in reactor, conditions such as its reaction temperature, concentration, pH value should be done the best evenly and are controlled at specified scope, should pay special attention to prevent that local concentration is too high, local temperature is too high or too low etc.Mix as early as possible and just become key condition.
In the reactor (reactor) of routine, finish, in order to help reactant to react more equably, usually all dispose motor-driven agitator in the reactor, agitator is made up of several blade sheets, in order to improve mixing efficiency, prior art has been innovated many patterns to the shape of blade sheet.In order to improve mixing efficiency, all adopt the rotating speed that improves agitator usually, bigger to the energy consumption that makes motor-driven agitator in the process of reacting.In large-scale reactor, the motor-driven agitator of configuration (adopting the multilayer agitator) is just bigger, energy consumption is just bigger, and the uniformity of mixing of materials is far unsatisfactory in the reactor, and the scale that has restricted reactor is amplified; Big when the viscosity of reaction mass, to reaction generate that grain size number is strict, reactant or product be heat-sensitive materials, when requiring reaction mass to mix rapidly, the conventional Liquid-phase reactor (reactor) of tradition is more difficult meeting the demands just.
The tradition Liquid-phase reactor is restricting the problem of fine chemistry industry industry development, mainly shows:
1. the big small-scale of reactor is restricted, and many enterprises have to use a lot of platform reactors, the multi-series operation.Multi-series operation causes that the total platform number of equipment is many, investment is many, control is numerous and diverse, potential safety hazard increases, total electric energy consumption height, the uniformity decline of product quality, cost rising.
2. the speed and the uniformity that multiple reactant mixes in the reactor is unsatisfactory.The prerequisite of reacting equably is to mix, and in order mixing as early as possible, except that selecting satisfied relatively blade construction, to improve mixed effect and mainly finishes by the rotary speed that improves agitator.From the design feature of reactor, after the agitator rotary speed surpasses certain rotating speed, improve rotating speed again and further improve mixed effect, and the power consumption of driving agitator rotation is quick increase.
3. be crystallization for the big reaction system of reaction mass viscosity, product and have requirement, reactor temperature and uniformity of temperature profile degree to require more strictness etc. that it is more incompatible that at present general structure of reactor just shows to crystallite size.
At present, the mixing of traditional Liquid-phase reactor and reaction efficiency become restriction and influence one of key factor of fine chemistry industry enterprise development.
