Description
Technical field
The invention belongs to the multi-phase flow technology field that relates in biomass thermal chemical conversion process, be specifically related to the hot gas-liquid-solid phase reaction device that a kind of microwave field and electromagnetic field intercouple.
Background technology
The gas-liquid-solid phase reaction device is multi-phase physics operating means or chemistry and the bioreactor that a class has the essential industry using value.The gas-liquid-solid phase reaction device is by gas phase, liquid phase and solid phase three phase compositions, and wherein liquid phase is continuous phase, and gas phase is discrete phase, and solid particle is suspended in gas phase and liquid phase.When the gas-liquid-solid phase reaction device during as chemical reactor, be no matter gas phase as inert gas, or solid phase is as catalyst, disturbance in enhanced reactor, strengthen contact between phase and phase, for promoting that chemical reaction fast and effeciently carries out significant.
Different from the Dual-Phrase Distribution of Gas olid bed, in the gas-liquid-solid three-phase bed, gas only can pass bed with the form of bubble, this is very disadvantageous for gas phase and contacting of other two-phases, especially for uneven due to cloth wind in bed, the situation that air pocket and local dead band occur, because when bubble passes through bed, only there is the gas at bubble interface to contact with solid-liquid two on every side, and the gas of bubble inside can not directly contact with them, when bubble passed bed fast, this part gas was fled from bed with the short circuit form.For, generally take two kinds of measures to strengthen the mixing of gas-liquid-solid three-phase at present.The first measure is the appropriate design gas distributed system, guarantees that fluidisation is even.When gas entered liquid phase with air-flow by gas distributed system, bubble had just formed.The size of bubble is permitted multifactorial the impact, and as the physical property of gas, liquid and solid particle, the operating condition of bed and the geometry of reactor, the geometry of reactor mainly just refer to the cloth wind system.Simultaneously, when cloth wind is uneven, be prone to local dead band in bed, the appearance in dead band also can suppress the mixing of gas-liquid-solid three-phase greatly.The second measure is that inner member is installed in bed.In bubble moved upward process, on the one hand minute bubbles can become air pocket by coalescence, and on the other hand, air pocket can be out of shape, breaking forms minute bubbles, that is to say, the merging of bubble with break and deposit.The effect of inner member is exactly the poised state of destroying air bubble growth, and the mechanism that makes air pocket split into minute bubbles surpasses the mechanism that minute bubbles are merged into air pocket, thereby promotes the growth of more minute bubbles.
In addition, for the carrying out that promotes to react, actual chemical reaction all carries out at a certain temperature, and this just need to heat reactor.Traditional heating mode is nothing more than dual mode.The first is external heat, is wound around heating wire or adds mounting clip sleeve to flow through hot flue gas reactor is outside, and obviously, this mode of heating heat transfer efficiency is low, and the rate of heat addition is slow, nor is convenient to the amplification of reactor.The second is inner heating, is mainly to adopt the mode of coiled pipe to stretch in bed heat pipe, then leads to steam in pipe, by steam indirect bed internal reaction thing.Although this mode of heating all is greatly improved on the efficiency of heating surface and speed; but stretching in bed, pipe can affect to a great extent the flow behavior of bed inner fluid; further the impact reaction is carried out; simultaneously; the continuous friction of solid particle meeting tube wall in the goods fluid process; to the serious wear of pipe, can affect the safe operation of equipment.

Concrete experimental procedure:
At first catalyst granules and the hot particle of disturbance are put into a body 1 in the 4:1 ratio, open the liquid phase injection apparatus and introduce the water bio oil.10 liquid phase playpipes 10 pass a body 1 wall from bed body 1 left side and enter in a body 1, liquid phase playpipe 10 stretch into be placed on after a body 1 one ends sealings with conduit saddle 7 that bed body 1 Right Inboard top is connected on, and keep the distance of 5mm with the right side wall, liquid phase playpipe 10 near bed body 1 front and back side wall surface is 45mm with the wall distance, and the distance between adjacent liquid phase playpipe 10 is 90mm, offer spray-hole 4 on the tube wall of every liquid phase playpipe 10, spray-hole 4 diameters near bed body 1 left side wall are 4mm, then increase gradually along the mobile direction of jetting fluid, until near bed body 1 right side wall, spray-hole 4 diameters are 8mm, like this, jetting fluid all equates in the pressure drop at spray-hole 4 places, guaranteed that the water bio oil equates from the flow that spray-hole 4 ejects.Spray-hole 4 at pipe end is 45mm with the tube wall distance, and adjacent spray-hole 4 spacings are 50mm, and the direction of adjacent spray-hole 4 and vertical plane angle are ± 30 °.
Simultaneously, fluidized gas hydrogen is introduced female pipe 16, female pipe 16 is dispensed to hydrogen every wind-distributing pipe 14 again.Wind-distributing pipe 14 passes a body 1 wall from bed body 1 right side and enters in a body 1, be placed on the conduit saddle 7 that is connected with the left inside side lower part of bed body 1 after other end sealing, and with the distance of left side wall maintenance 5mm.Like this, wind-distributing pipe 14 length in bed body 1 are 985mm, wind-distributing pipe 14 near bed body 1 front and back side wall surface is 45mm with the wall distance, and the distance between adjacent wind-distributing pipe 14 is 90mm, simultaneously, offer pore 20 on the tube wall of every wind-distributing pipe 14, pore 20 diameters near bed body 1 right side wall are 2mm, then increase gradually along the fluidized gas flow direction, until near wall on the left of the bed body, pore 20 diameters are 6mm, like this, fluidized gas all equates in the pressure drop at pore 20 places, has guaranteed that hydrogen equates from the flow that aperture 20 ejects.Pore 20 at pipe end is 45mm with the tube wall distance, and adjacent pore 20 spacings are 50mm.The pore 20 of adjacent wind-distributing pipe 14 is towards difference, and wind-distributing pipe 14 pores 20 near wall are oriented straight down, and wind-distributing pipe 14 pores 20 that are adjacent are oriented straight up, so the sample interlaced arrangement.Hydrogen enters in a body 1 by pore 15, and keeping apparent cross section gas speed is to change between 0.5 ~ 2m/s, and bed begins fluidisation like this, and hydrogen passes bed with bubble form, and solid particle is suspended in air-flow and liquid stream.
