As shown in Figure 2, slurry reactor piece-rate system provided by the invention comprises: paste state bed reactor 10 and equipment for separating liquid from solid, this equipment for separating liquid from solid comprises the inner eddy flow separator 11 that is arranged in the described paste state bed reactor 10, this inner eddy flow separator 11 comprises at least one suction tube 4, and this suction tube 4 can be drawn into the serum materials in the described paste state bed reactor 10 in the described inner eddy flow separator 11 and carry out the solid-liquid cyclonic separation.
Compare with traditional slurry reactor piece-rate system, the main improvements of slurry reactor piece-rate system of the present invention are: be provided with the inner eddy flow separator 11 that is applicable to carry out in this paste state bed reactor 10 inside centrifugation in the inside of paste state bed reactor 10 (dotted line schematically shows in Fig. 2), thereby can carry out centrifugation to the serum materials in the paste state bed reactor 10 in the inside of this paste state bed reactor 10.
The inner eddy flow separator 11 that is arranged in paste state bed reactor 10 sucks the inside of this inner eddy flow separator 11 by at least one suction tube 4 with serum materials, to carry out cyclonic separation.Inner eddy flow separator 11 can utilize suction tube 4 to draw serum materials in the paste state bed reactors 10 by the mode of any appropriate.For example, can utilize the inside and outside pressure differential of inner eddy flow separator 11, can also form negative pressure in the inside of inner eddy flow separator 11 by pump.
This inner eddy flow separator 11 can be can be by suction tube 4 with absorb the arbitrarily cyclone separator of cyclone separator 11 inside of the serum materials in the paste state bed reactor 10.Preferably, the inner eddy flow separator 11 that is arranged in the paste state bed reactor 10 is above-mentioned cyclone separator provided by the present invention.Can both be in any suitable manner combine with the inner eddy flow separator 11 here individually and/or in combination about the above-mentioned feature of cyclone separator provided by the present invention.
For example, preferably, inner eddy flow separator 11 comprises that top is the cylindrical of top closure, the bottom is obconic cyclone separator main body 1, the upper end of suction tube 4 is communicated with eddy flow charging aperture 5 in the cyclone separator main body 1, the lower end of suction tube 4 can extend in the serum materials 12 in the paste state bed reactor 10, the bottom of inner eddy flow separator main body 1 is provided with solid discharge nozzle 3, be connected with baiting valve 6 on this solid discharge nozzle 3, equipment for separating liquid from solid also comprises liquid discharge nozzle 2, one end of liquid discharge nozzle 2 is positioned at cyclone separator main body 1, the other end of liquid discharge nozzle 2 passes the top of cyclone separator main body 1 and is positioned at the outside of paste state bed reactor 10, is delivered to the reactor outside thereby inner eddy flow can be separated the liquid that obtains.
For another example, preferably, the bottom level of solid discharge nozzle 3 is than the high 50-500mm of bottom level of suction tube 4, so that when solid discharge nozzle 3 and suction tube 4 all insert serum materials, mineralization pressure is poor between the bottom of the bottom of solid discharge nozzle 3 and suction tube 4.
Be arranged on the embodiment of described paste state bed reactor 10 according to inner eddy flow separator 11, when carrying out cyclonic separation, need to carry out inner solid-liquid cyclonic separation step, this inside solid-liquid cyclonic separation step comprises being drawn in the inner eddy flow separator 11 by at least one suction tube 4 by reacting the serum materials that produces in the paste state bed reactor 10, in this inner eddy flow separator 11 serum materials that transports is carried out inner solid-liquid cyclonic separation.
Serum materials in the paste state bed reactor 10 generally includes solid catalyst particle and liquid fuel.This serum materials is absorbed behind the cyclone separator 11 by at least one suction tube 4, in this inner eddy flow separator, carry out cyclonic separation, thereby make solid catalyst particle (certainly, it is remaining also may still can be doped with a small amount of liquid in this solid catalyst particle) be deposited on the bottom of inner eddy flow separator 11, and then can discharge in the paste state bed reactor 10 by solid discharge nozzle 3, to continue its catalytic action of performance; Separate the liquid fuel that obtains and then can on the top of inner eddy flow device 11 (being positioned on the solid catalyst particle), can be discharged to the outside by liquid discharge nozzle 2.
This shows, in slurry reactor piece-rate system provided by the present invention, and the inside that utilizes the feed separation method that is used for slurry reactor that this piece-rate system carries out can be implemented in paste state bed reactor realizes the separation to serum materials, thereby overcome the defective that must carry out centrifugation in the outside of paste state bed reactor traditionally and bring.
Preferably, inner solid-liquid cyclonic separation step comprises that also the solid material that the solid-liquid cyclonic separation is obtained is discharged into (this can realize by the baiting valve 6 that connects on the solid discharge nozzle 3) in the described paste state bed reactor 10 off and on, the liquid material that the solid-liquid cyclonic separation is obtained is transported to the outside of paste state bed reactor 10, thereby realizes separating of catalyst granules and liquid fuel product.
For the further degree of purity that improves the liquid material that obtains through the inner eddy flow separating step, and catalyst as much as possible is directly recycled in the Returning reactor, preferably, as shown in Figure 2, be provided with piping filter 13 at liquid discharge nozzle 2.Thereby, utilize piping filter 13 to carry out filtration step to the liquid material that obtains through described inner solid-liquid cyclonic separation, with further realization Separation of Solid and Liquid.
When the liquid material that obtains after separating passes through this piping filter 13 by the pipeline conveying, the tiny solid particle that is entrained in this liquid material is just remained by this piping filter 13, but liquid still allows to pass through, thus make by after the degree of purity of liquid higher.Certainly, if the degree of purity of the liquid material that obtains after the inner solid-liquid cyclonic separation of process has reached required requirement, just need not to arrange in addition piping filter 13, also need to after separation, not carry out filtration step by this piping filter 13.
Piping filter 13 can adopt the filter of realization Separation of Solid and Liquid commonly used, for example, and basket filter, l type filter or y-type filter.Usually, the filtering accuracy of filter (allowing the maximum particle diameter by the particle of this filter) is about the 5-10 micron.
When filtration was carried out a period of time of after, because gathering of tiny solid particle can cause the decline of strainability.Thereby as shown in Figure 2, piping filter 13 is connected with backwash tube 14, and namely backwash tube 14 links to each other with piping filter 13, thereby can utilize the recoil medium by backwash tube 14 that piping filter 13 is recoiled.Separation method provided by the present invention comprises that also utilization recoil medium carries out the recoil step of backflush process to piping filter 13.
The recoil medium can be not affect gas or the liquid that paste state bed reactor 10 internal reactions carry out, and for example, the recoil medium can be any one in nitrogen or the inert gas; The recoil medium can also be the part of the comparatively pure liquid material of acquisition after separating.
For fear of the interference between inner solid-liquid cyclonic separation step and the recoil step, for same inner eddy flow separator 11, inner solid-liquid cyclonic separation step is not carried out simultaneously with the recoil step, and the step that namely recoils and inner solid-liquid cyclonic separation step hocket.
Specifically, as shown in Figure 2, be provided with backwash valve 15 at backwash tube 14, in the pipeline of carrying liquid material, be provided with liquid bleeder valve 16.
When carrying out inner solid-liquid cyclonic separation step, need to be transported to the outside with separating the liquid material that obtains, this moment, backwash valve 15 cut out, and liquid bleeder valve 16 is opened.
And when needs recoiled step, backwash valve 15 was opened, and passed into the recoil medium of relatively high pressure, simultaneously liquid bleeder valve 16 cut out, and medium directly flows away by liquid bleeder valve 16 to prevent from recoiling.At this moment, the recoil medium can only wash by piping filter 13 and to this filter.
As shown in Figure 4, for the recoil medium of gaseous state is provided to backwash tube 14, be provided with the source of the gas (not shown) and be communicated with the also gas buffer tank 20 of stored-gas with this source of the gas, also be provided with heater 21 and air intake control valve 22 in the pipeline between source of the gas and gas buffer tank 20.Because environment temperature is relatively high in the paste state bed reactor, be about 200 ℃ to 300 ℃, gas be heated to by heater 21 with paste state bed reactor in after the close temperature of environment temperature, recycle this gas and recoil, thereby can not affect normally carrying out of paste state bed reactor internal reaction.Gas buffer tank 20 communicates with backwash tube 14 by pipeline, with the recoil medium to backwash tube 14 supply gaseous states.
Gas buffer tank 20 also is provided with gas exhausting valve 23, can control the relatively high pressure gas discharging in the gas buffer tank 20 in atmosphere or other containers.By air intake control valve 22 and gas exhausting valve 23, can regulate the gas pressure in the gas buffer tank 20, so that the gas in the gas buffer tank 20 is applicable to the step that recoils.
Because for same inner eddy flow separator, inner solid-liquid cyclonic separation step can not be carried out simultaneously with the recoil step, therefore in order to ensure the liquid material after can obtaining constantly to separate, preferably, described equipment for separating liquid from solid comprises two described inner eddy flow separators 11 and 11 ' that can be used alternatingly, each described inner eddy flow separator is provided with piping filter and backwash tube, as shown in Figure 3.
That is to say that the inner eddy flow separators 11 and 11 ' that are arranged in the paste state bed reactor 10 are two, thereby so that one of them when carrying out described recoil step, another carries out described inner solid-liquid cyclonic separation step.That is, there is not the stage that is in simultaneously the step that recoils in these two inner eddy flow separators 11 and 11 '.
When carrying out inner solid-liquid cyclonic separation step with reference to 3, one inner eddy flow separators of figure 11, liquid bleeder valve 16 is opened, and backwash valve 15 cuts out.After work a period of time (such as 10-15 minute), liquid bleeder valve 16 cuts out, backwash valve 15 is opened simultaneously, another backwash valve 15 ' cuts out, another liquid bleeder valve 16 ' is opened, at this moment, inner eddy flow separator 11 step that recoils, and another inner eddy flow separator 11 ' carries out inner solid-liquid cyclonic separation step.After the recoil step of inner eddy flow separator 11 is carried out a period of time (such as 5 second-3 minute, the time of the step that recoils is shorter with respect to the time of carrying out inner solid-liquid cyclonic separation step), backwash valve 15 cuts out.At this moment, inner eddy flow separator 11 step that neither recoils is not carried out inner solid-liquid cyclonic separation step yet.When another inner eddy flow separator 11 ' carries out inner solid-liquid cyclonic separation step after a period of time (such as 10-15 minute), again to this another inner eddy flow separator 11 ' step that recoils.So constantly repeat this process, be used alternatingly two inner eddy flow separators 11 and 11 '.
Certainly, also can adjust the time of recoil step, so that there is not out-of-work situation in two inner eddy flow separators 11 and 11 '.
In order to store the liquid material that is transported to the paste state bed reactor outside, preferably, described slurry reactor piece-rate system also comprises the storage tank 17 that is positioned at paste state bed reactor 10 outsides, and this storage tank is communicated with the described other end of liquid discharge nozzle 2.Thereby, after paste state bed reactor 10 interior outputs, this liquid material can be stored into the storage tank 17 that is arranged in described paste state bed reactor 10 outsides at the liquid material after the separation.
Generally, in carrying out course of reaction, the operating pressure in the paste state bed reactor 10 is 2.0-5.0Mpa.Enter in the storage tank for the ease of separating the liquid material that obtains, preferably, pressure in this storage tank 17 slightly is lower than the operating pressure in the paste state bed reactor 10, and further preferably, the operating pressure in the pressure ratio paste state bed reactor 10 in the storage tank 17 hangs down 0.2-0.5Mpa.And, for the gas that makes paste state bed reactor inside is in time discharged after finishing reaction, can also speed to exit (as shown in Figure 4) by pipeline, with the pressure of control paste state bed reactor 10 inside.
In addition, in order to ensure the quality that is stored in liquid material in the storage tank 17, preferably, the temperature in the temperature of storage tank 17 and the paste state bed reactor 10 is consistent substantially.This can realize by in storage tank 17 heater being set.
For the serum materials in the paste state bed reactor 10 is entered in the inner eddy flow separator 11 by suction tube 4, to carry out cyclonic separation, preferably, be provided with pump at liquid discharge nozzle 2, the operation of described pump is so that the serum materials 12 in the paste state bed reactor 10 can enter carries out the solid-liquid cyclonic separation in the inner eddy flow separator 11 and make isolated liquid material can derive paste state bed reactor 10.Thereby, when inner eddy flow separator 11 carries out inner solid-liquid cyclonic separation step, can start this pump, can be in the inner eddy flow separator 11 inner negative pressure that form, thereby the serum materials 12 in the paste state bed reactor 10 can be entered in the inner eddy flow separator 11, also the liquid material that separate to obtain can be pumped to internally the outside of paste state bed reactor 10 in the cyclone separator 11, perhaps this liquid material be transported in the storage tank 17 that stores liquid material (if described piece-rate system is provided with storage tank 17).
Liquid material is being transported in the embodiment of storage tank 17, the negative pressure that can also not utilize pump to produce realizes that serum materials is drawn in the inner eddy flow separator 11.Specifically, the position of storage tank 17 can be arranged so that the liquid level of these storage tank 17 interior liquid materials is lower than the liquid level of serum materials 12 in the paste state bed reactor 10, carry out the solid-liquid cyclonic separation thereby make paste state bed reactor 10 interior serum materials 12 can under the effect of paste state bed reactor 10 inside and outside differential pressures, enter inner eddy flow separator 11, and make isolated liquid material can derive paste state bed reactor 10.
In this case, because the setting of having omitted pump, thereby can save the energy, also can reduce the maintenance cost of piece-rate system.
Certainly, can also adopt various technological means commonly used to realize that pressure in the storage tank 17 is a little less than the pressure in the inner eddy flow separator 17.
In order further to improve the degree of purity of the liquid material that is transported to paste state bed reactor 10 outsides, preferably, described equipment for separating liquid from solid also comprises the outside cyclone separator 18 that is positioned at outside the paste state bed reactor 10, carries out outside solid-liquid cyclonic separation step by this outside cyclone separator 18.
For example, the charging aperture of this outside cyclone separator 18 can be communicated with the described other end of liquid discharge nozzle 2, carrying out further solid-liquid cyclonic separation through the liquid material that inner eddy flow separator 11 separates.In this situation, described outside solid-liquid cyclonic separation step comprises utilizes the 18 pairs of isolated liquid materials of outside cyclone separator that are positioned at outside the paste state bed reactor 10 to carry out further solid-liquid cyclonic separation.Thereby, separating the liquid material that obtains through the inner eddy flow separating step is imported into again in the outside cyclone separator 18, and carry out outside cyclonic separation step by this outside cyclone separator 18, thereby further remove the impurity that is entrained in the liquid material that separation obtains through the inner eddy flow separating step, can further improve its degree of purity.
If be provided with piping filter 13 in liquid discharge nozzle 2, then said external solid-liquid cyclonic separation step comprises that the liquid material that utilizes after being positioned at paste state bed reactor 10 18 pairs outer of outside cyclone separators step being separated after filtration carries out further solid-liquid cyclonic separation.In this embodiment, because the liquid material that separates acquisition through the inner eddy flow separating step has passed through filtration treatment through piping filter 13 time, thereby the fluent material after outside cyclone separator 18 separates can obtain better degree of purity.
For another example, be provided with in the situation of storage tank 17 in piece-rate system, the charging aperture of outside cyclone separator 18 can be communicated with storage tank 17, the material in the storage tank 17 is carried out further solid-liquid cyclonic separation.In this situation, described outside solid-liquid cyclonic separation step comprises utilizes the liquid material that is arranged in the 18 pairs of storage tanks 17 of outside cyclone separator outside the paste state bed reactor 10 to carry out further solid-liquid cyclonic separation.
Said external cyclone separator 18 can have one or more, can be according to the requirement of the requirement of concrete workplace and separation accuracy and selected.Have relatively high degree of purity at the liquid material that separates acquisition through outside cyclone separator 18, this liquid material is used for piping filter 13 is carried out above-mentioned recoil step also as the recoil medium.Then can again be transported in the paste state bed reactor 10 and separate the solid particle (less catalyst granules, usually also may be doped with liquid becomes paste-like) that obtains through outside cyclone separator 18, continue its catalytic action of performance.As shown in Figure 4, by pump 26 this paste-like material is transported in the paste state bed reactor 10 by the first pipeline 24.
In order further to obtain the higher liquid feul of degree of purity, preferably, described equipment for separating liquid from solid also comprises the membrane separator 19 that is positioned at outside the described paste state bed reactor 10 again, and described separation method also comprises the film separating step.
