Technical field

The present invention relates to be used in carbon based substances is changed into the fluid flow bed in the process of Sweet natural gas and activated carbon, relate more particularly to the speed of fluid flow.

Background technology

For a long time, coal is used as fuel source.Along with the searching of alternative fuel is increased, several contrivers have sought to relate to the further development technique of the use of coal.These contrivers begin to recognize that the Sweet natural gas of in coal, finding is not limited to coal; But find that in various forms of artificial and naturally occurring materials said material includes but not limited to municipal solid wastes, sewage, timber waste, biomass, paper, plastics, danger wastes, tar, pitch, active sludge (activated sludge), rubber tyre and oil base resistates.

Problem generally is not where people should seek Sweet natural gas, but how to discharge Sweet natural gas.This has just caused several kinds of different limited gasification liquefaction technologies.These system overview ground comprise lower suction type gasification, updraft type gasification and fluidized-bed gasification.

The lower suction type gasification is also referred to as " forward flow configuration system ", relies on gravity to move raw material, and said raw material perhaps is a coal.Combustion system flows with raw material, thereby makes resulting ash or slag fall the bottom.Said ash or slag are that danger wastes and former state are handled.This partial combustion system has obtained low BTU gas, and said gas must clean comprehensively.

The updraft type gasification is also referred to as " contracurrent system ", uses gas blower to guide said raw material upwards through said system.Combustion Source is usually along opposite with said raw material or vertical direction channeling conduct.Ash and slag are fallen the bottom, and it is collected as danger wastes here.This is the partial combustion system, and it causes low BTU gas and tar, and said gas and tar must clean before use.

Conventional fluidized-bed uses sand, charcoal or its some combinations.Fluid, normally air or steam guide to the raw material above it through sand.The common anoxic of environment, thus partial combustion caused.Temperature is low relatively, thereby causes low BTU gas, and said gas must clean before use comprehensively.Ash is corrosive, thus cause ls use so that infection minimize.Some instances of fluidization are following:

Giglio (No. the 2006/0130401st, U.S. Patent application) discloses the method for co-production activated carbon in the circulating fluidized bed gasifying process.Blacking is handled in fluidized-bed, thereby forms synthetic gas and charcoal.

utilizes steam and carbonic acid gas that charcoal is become activated carbon in step subsequently.The Giglio instruction uses activated carbon to clean synthetic gas and divided gas flow and activated carbon.The synthetic gas and the solids constituent that cleaned leave.Giglio uses separator that activated carbon is separated with said raw material with Sweet natural gas.That is, the air-flow through fluidized-bed is not used for the composition according to the density separation blacking.

People such as Jha (USP the 5th, 187, No. 141) disclose the method for being made activated carbon through gentle gasification and hydrogenation by coal.At first coal being heated to water is evaporated to and is lower than the temperature of volatilization between removing.Mainly be in the nonoxidizing atmosphere dry coal to be heated to volatilize and to remove contained volatile matter and produce charcoal then.In second step, charcoal is carried out hydrogenation process so that the carbon activation.Air-flow through fluidized-bed is not used for according to the composition of density separation blacking.

People such as Ueno (No. the 2003/0027088th, U.S. Patent application) disclose the method for handling combustible waste material.Combustible waste material comprises paper, plastics, coal, tar, pitch, active sludge and oil base resistates.

combustible waste material carbonization under about 400～600 ℃ temperature.The material of carbonization is about 1000～1300 ℃ temperature of experience under inert atmosphere then.This has just driven volatile matter away and possibly make the carbon activation.The product of carbonization is blown to exhaust for example in the volatile matter, with purifying exhaust gas.(exhaust is preferably from waste incineration, power house, steel-smelting electric furnace, fragment smelting furnace and sinter machine.Although) admit to contain objectionable impurities among them, will said volatile matter as the thermal source of carburising step.

The speed of fluid flow is not considered the benefit of fluid flow rate (flow rate) usually without discussion yet.Needed is the flow of gas in the fluidized-bed between carbon based material to natural gas and activated carbon transition phase, and it has obtained extending beyond the useful result of burning or conversion rate.Make us desirably, said flow is suspended in needs material on the fluidized-bed and does not need material sepd in bed.

Summary of the invention

The present method that blacking is processed into Sweet natural gas and activated carbon can comprise following steps: raw material is placed on the fluidized-bed; The guiding non-oxidized gas is through said fluidized-bed; Regulate the speed of said gas, make that said gas must be enough to said raw material is stayed on the said fluidized-bed and must be enough to remove activated carbon and volatile matter soon slowly.

In a preferred method, said method can comprise following steps: raw material is placed on the fluidized-bed; Guiding superheated non-oxidized gas is through said fluidized-bed; Regulate the speed of said overheated gas, make that said gas must be enough to said raw material is stayed on the said fluidized-bed and must be enough to remove activated carbon and volatile matter soon slowly; Use said activated carbon to obtain cleaning, thereby form the Sweet natural gas and the activated carbon of cleaning by volatile matter; Said Sweet natural gas is separated with said activated carbon; Said fluidized-bed is got back in the said Sweet natural gas recycling of a part; Collect the part of the not recycling of said Sweet natural gas; And the said activated carbon of collection.

Advantageously, be connected to glibly and the pressure cabin (plenum) that is communicated with away from fluidized-bed can be in the position of rising with respect to fluidized-bed, directly mix with activated carbon to allow volatile matter, thus Sweet natural gas that obtains cleaning and activated carbon.

As another advantage, said speed makes fluidized-bed maintain the fresh supply of blacking and finished material is cleaned out (purge) from fluidized-bed.

As another advantage, said method does not have water and oxygen fully, thereby avoids partial combustion, and for example charing, or perfect combustion are for example grey, thereby make blacking directly be transformed into activated carbon.

As another advantage, said speed plays a role as gravity separator, and said gravity separator relies on the variable density between the mixture of said raw material and activated carbon and volatile matter.

These advantages will be through reading following description and becoming high-visible with reference to accompanying drawing with other advantages.

Description-technology/treater

Reference numeral 110-126 is used to represent process step, is illustrated on the schema of specifying Fig. 1.Reference numeral 130 to 300 is used for the indication equipment assembly, is illustrated on Fig. 2 to Fig. 4.

The present method that raw material 134 is processed into the carbon material 157 of first volatile matter 154 and poor hydrogen can comprise first step 110, selects raw material 134, and is as shown in Figure 1.The suitable material that is used for producing raw material 134 includes but not limited to: coal, municipal solid wastes, sewage, timber waste, biomass, paper, plastics, danger wastes, tar, pitch, active sludge, rubber tyre and oil base resistates.Coal is a preferred feedstock.The grade of coal is unimportant, because this is not to relate to partially or completely incendiary technology.Yet, comprise that the material of the humidity of coal should be in addition dry.

Then, raw material 134 is placed on the fluidized-bed 144, on Fig. 1, is expressed as step 112.This step is preferably carried out with controlled way, in order to avoid oxygen and/or water are along with raw material 134 gets into together.For example, raw material 134 can get into through air lock system 135.

Air lock system 135 can comprise hopper 136, wimble 138, rotation vent plug 140 and have sleeve 142a and the sliding gate 142 of aperture 142b.Raw material 134 from hopper 136 is directed into rotation vent plug 140 by wimble 138.Rotate rotation vent plug 140, raw material 134 is dropped to the aperture 142b of sliding gate 142.Through sleeve 142a, the vibration of sliding gate 142 is directed into raw material 134 on the skewed slot 184, and raw material 134 drops on the fluidized-bed 144 there.When arriving skewed slot 184, raw material 134 can run into the barometric point that increases slightly.The atmosphere of this pressurization is guaranteed all to keep outside direction through any air-flow of air lock system 135, rather than inwardly.Other air lock systems all are that those of ordinary skill in the art knows, and can replace air lock system 135 disclosed herein to use.

Raw material 134 is suspended in the superheated Sweet natural gas 149 of fluidized-bed 144.The raw material 134 that is suspended on the fluidized-bed 144 should suspend by this way: make raw material 134 receive and be in for example superheated Sweet natural gas 149 supports of gasiform material.Raw material 134 swims in the air-flow.Be directed to raw material 134, possibly formed air-flows and be preferred gaseous substance by the superheated gas 149 of hydrogen or water expansion.

Referring to 114 on Fig. 1, superheated Sweet natural gas 149 is conducted through fluidized-bed 144, and this fluidized-bed 144 changes into raw material 134 in the carbon 157 of first volatile matter 154 and poor hydrogen.The carbon 157 of poor hydrogen is activated carbon 156 preferably, and also is applicable to the carbon 157 of poor hydrogen for the description of activated carbon 156.Consider the granularity of raw material, need to select temperature, because volatile matter 154 should all enough be discharged soon, so that with the carbon activation.The diameter of raw material 134 should be between 1/16 to 5/8 inch, and diameter dimension is preferably between 1/8 to 1/4 inch.This can be called as hurried heating.Superheated Sweet natural gas 149 cleans, and can be the Sweet natural gas 149 that is obtained by technology of the present disclosure, is called recycling here.Superheated Sweet natural gas 149 can be heated to the temperature of 1000-1500 ° of F, is preferably 1000-1200 ° of F.Why ideal is because they with raw material 134 hurried heating, for example remove volatile matter apace in the several seconds to these temperature.The rapid evaporation of volatile matter 154, expansion are with the carbon activation.

Key element 116 referring to Fig. 1; The speed of superheated Sweet natural gas 149 is adjusted to this state: Sweet natural gas 149 is slowly to being enough to that raw material 134 is stayed on the fluidized-bed 144; Near the mixture that is enough to remove activated carbon 156 and volatile matter 154, wherein separate and when any feedstock conversion becomes volatile matter 154 and activated carbon 156, to carry out.Based on the density of material, for example the less material of density blows away (with controlled way), and this speed has been separated raw material 134, activated carbon 156 and volatile matter 154.The density of raw material 134 is greater than activated carbon 156, and the density of activated carbon 156 is then greater than volatile matter 154.Thereby the speed of setting air-flow, so that with the density materials with smaller, for example the mixture of volatile matter 154 and activated carbon 156 moves and for example is transported to first pressure cabin (plenum) 152, lets raw material 134 be retained on the fluidized-bed 144, is used for further processing.This speed is slowly to not removing raw material 134.Along with fluidized-bed 144 continues volatile matter 154 is separated with raw material 134, raw material 134 has directly changed into activated carbon 156, and need not the intermediate steps of charing.Because anoxic, this system can partially or completely not burn, thereby can not form charcoal or ash.Flow depends on the size of fluidized-bed.The flow that very little bed can have 10 cubic feet/min; And the flow that very big bed can have 20,000 cubic feet/min.Ideally, speed most preferably is about 6000 cubic feet/min between the 5500-6500 cubic feet/min.

Displacing device (displacer) 182 can be arranged in the skewed slot 184, but perhaps is vertical vibration, and the size that can be used for regulating open base area and be fluidized-bed 144 is volume for example.This has improved the speed of Sweet natural gas 149 again, supposes that the for example mobile volume maintenance of total flux is constant.Displacing device 182 helps more efficiently from fluidized-bed 144 de-carbon that gets on, and keeps fluidized-bed 144 to clean more.In fact, the effect of displacing device 182 realizations surpasses through using one or more gas blower 168 raising performances to come change speed.Preferred gas blower 168 is described in this joint of description-gas blower at title as follows.

Activated carbon 156 mixes from fluidized-bed 144 with volatile matter 154, until the whirlpool separator that will discuss 158, referring to the key element 118 of Fig. 1.Activated carbon 156 cleaning volatile matters 154 in the mixture (or blended gleanings) of volatile matter 154 and activated carbon 156 are so that form the Sweet natural gas 149 and activated carbon 156 of cleaning.The compound of hazardous compound such as mercury, chlorine and sulphur pools together, and is collected and is stored in wherein by activated carbon 156.Known at hazardous compound that raw material 134 is normally found in the coal only in burning or be applied under the condition of strong acid and just can discharge, and in the present invention, both of these case all not have discovery.So can believe: hazardous compound can not discharge from raw material 134, but is retained in the activated carbon 156, can not become the part of volatile matter 154 forever.Test to this technology does not show that any hazardous compound is arranged in the volatile matter 154, and the volatile matter 154 that leaves fluidized-bed 144 is Sweet natural gases 149 of cleaning.Should be noted that raw material 134 possibly contain inflammable gas, it can be a volatile matter 154, but the carbochain longer than Sweet natural gas 149.Yet, but allowing to clean, limit is that any objectionable impurities can discharge really.Can begin as early as possible to adopt activated carbon 156 to clean volatile matter 154 so that form the Sweet natural gas 149 and activated carbon 156 of cleaning, when when volatile matter 154 and activated carbon 156 to be ready leaving fluidized-bed 144, cleaning course lasts till till the completion always at least.

In whirlpool separator 158, activated carbon 156 is separated with Sweet natural gas 149, referring to the key element among Fig. 1 120.The size of whirlpool separator 158 and mode all are that those skilled in the art knows.Sweet natural gas 149 can extract with gas blower 168 through being connected to second pressure cabin 162 of whirlpool separator 158, and activated carbon 156 then comes out from the bottom settlings of separator 158.Resulting Sweet natural gas 149 is a moderate BTU Sweet natural gas (1000Btu/SCF).The activated carbon of collecting from the bottom of whirlpool separator 158 156 can be cooled, screening, classification/process and pack are for sale, perhaps can keep being heated and hydrogenation, thereby form other Sweet natural gas 149.The diameter dimension of activated carbon 156 changes between powder to 1/4 inch.Activated carbon 156 can cool off in closed cooling transporting belt.

Recirculation step 122 in Fig. 1, a part of Sweet natural gas 149 of about 10% can be recycled gets back to fluidized-bed 144; About 5% or a part of Sweet natural gas still less 149 can recycling get into burners 180 and burn, burner 180 is used for the gas of superheated fluidized-bed 144.There is not that part of Sweet natural gas 149 of recycling to be collected, shown in the step 124 among Fig. 1.Collecting step 124 can comprise: with the Sweet natural gas cooling, compress and pack for sale.The activated carbon of collecting from the bottom of whirlpool separator 158 156 can be packed for sale, shown in the step 126 among Fig. 1.

More than disclosed be the preferred method that raw material 134 is processed into Sweet natural gas 149 and activated carbon 156.This technology is not to be burning or partially combusted technology, and is based on the separating technology of temperature and density.What below describe is the preferred equipment 130 of implementing disclosed technology.Will be with reference to figure 2.

Treater 130 can have the hopper 136 that is connected to air lock system 135.Air lock system 135 can have wimble 138, rotation vent plug 140 and sliding gate 142, and this sliding gate 142 is arranged in sleeve 142a and defines aperture 142b.Raw material 134 operable communication in wimble 138 and the hopper 136 and place of working are connected to rotation vent plug 140, and said rotation vent plug 140 can be worked and is connected to aperture 142b.Rotating screw brill 138 moves to rotation vent plug 140 with raw material 134 from hopper 136.Rotating rotation vent plug 140 drops to raw material 134 among the aperture 142b of sliding gate 142.Sliding gate 142 in the vibration sleeve 142a lets raw material 134 landing pass aperture 142b, falls into skewed slot 184 and drops on the fluidized-bed 144 again.

The substituting air lock system 135 that can use those of ordinary skill in the art to know.There are not air or moisture through air lock system 135.Both of these case all can cause burning, and burning is not the part of this technology.

After air lock system 135, raw material 134 arrives fluidized-bed 144.Usually, fluidized-bed all is the bed that relies on sand or charcoal to pass through as gas.The present invention adopts metal grate 146, and it all over spreads all over aperture 148; Aperture 148 is littler than feed particles 134.Can also use oxygen-free substituting gas, Sweet natural gas 149 can be through fluidized-bed 144 guiding and by superheated to above-mentioned temperature.Sweet natural gas 149 can be through 151 guiding of one or more conduits, and the quantity of bed conduit and structure make Sweet natural gas 149 on fluidized-bed 144, keep moving with even velocity through selection, and do not have the dead point basically.Above-mentioned speed suspends raw material 134, and volatile matter 154 and activated carbon 156 are blown into first pressure cabin 152.The first pressure cabin work is connected to fluidized-bed 144.Raw material 134 is on the fluidized-bed 144, and superheated Sweet natural gas 149 has then passed through fluidized-bed 144.

Sweet natural gas 149 through fluidized-bed 144 has speed.This adjustable-speed joint is to such point, and promptly Sweet natural gas 149 is slowly to being enough to that raw material 134 is stayed on the fluidized-bed 144, but near being enough to remove volatile matter 154 and activated carbon 156.So, Sweet natural gas 149 stream has just become to let the separator of raw material 134 and the mixture separation of activated carbon 156 and volatile matter 154, this isolating density that is based on.

Make us desirably; Volatile matter 154 is in general uniform mixing with activated carbon 156 152 li of first pressure cabins and arranges; The cloud that for example comprises volatile matter 154 and activated carbon 156 is arranged (cloud arrangement); So that cleaning volatile matter 154, if any hazardous compound is released to the words in the middle of the cleaning Sweet natural gas 149.(after the test, do not find that hazardous compound is released during this technology and on any point in the equipment as herein described, so volatile matter 154 is cleaning Sweet natural gases 149.) pressure cabin 152 is communicated with fluidized-bed 144 fluids, as the susceptor of isolating volatile matter 154 and activated carbon 156 mixtures therefrom.First pressure cabin 152 that is communicated with fluidized-bed 144 fluids can be arranged in the point that is higher than fluidized-bed 144 and have certain size and be suitable for accepting volatile matter 154 and activated carbon 156.Allow remaining volatile matter 154 to separate with the activated carbon 156 of 152 li of first pressure cabins, first pressure cabin remains on about temperature or its of fluidized-bed 144.

First pressure cabin 152 is connected to and is emptied in the whirlpool separator 158, and whirlpool separator 158 is volatile matter/activated carbon separators 138.Whirlpool separator 158 preferably is heated to keep the temperature of Sweet natural gas 149.Should be noted that the activated carbon 156 in the whirlpool separator 158 is in the temperature of rising, and itself can in nonoxidizing atmosphere, carry out hydrogenation, thereby form other Sweet natural gas 149.Whirlpool separator 138 separates volatile matter 154 (Sweet natural gas 149) and activated carbon 156 based on proportion.(note: volatile matter 154 after the activated carbon 156 with 152 li of first pressure cabins mixes, be cleaning Sweet natural gas 149, and after first pressure cabin 152, volatile matter 154 has been exactly interchangeable term with Sweet natural gas 149.) in essence, activated carbon 156 can drop out from the aperture 160 of whirlpool separator 158 bottoms.Volatile matter 154 is drawn into second pressure cabin 162 that is connected to whirlpool separator 158.Said second pressure cabin 162 is designed for cooling, compression, recycling, packing Sweet natural gas, will describe it now.

Second pressure cabin 162 can comprise and is placed the one or more gas blowers 168 that are used for keeping or regulating Sweet natural gas 149 speed.Second pressure cabin 162 is connected with the 4th pressure cabin 166 with the 3rd pressure cabin 164 respectively.A part of Sweet natural gas 149 of about 10% can be conducted through the 3rd pressure cabin 164, arrives heat exchanger 170, and returns fluidized-bed 144.(thermofin 147 can be around fluidized-bed 144 or entire equipment 130.) before Sweet natural gas 149 gets into fluidized-bed 144, heat exchanger 170 superheated Sweet natural gases 149.All the other that part of Sweet natural gases 149 of about 90% are imported into the 4th pressure cabin 166, and this part Sweet natural gas can interact with heat exchanger 172, low pressure compressor 174 and large vol holder 176 with cooling there, prepares to sell.The burner 180 that gas pipeline 178 links from large vol holder 176 guiding and heat exchanger 170.Burner 180 gas-firing 149 and heat exchanger 170 heat supplies.Burned gas from burner 180 can upwards be imported chimney 150.Should be noted that fluidized-bed can be connected with the relation of sealing with each pressure cabin, thereby form closed loop system, unique discharging of wherein coming from said system is from chimney 150.
