Description

The method for the treatment of solid material at high temperatures
The present invention relates at high temperature to handle solid material for example refuse and biological sludge, from said process, reclaim the method for the process gas (process gas) that heat and cooling produce.
Because for example increase of MSW amount of solid material, handle them by burning and become the energy that utilizes in the refuse, for example be used to produce the more and more significant method of steam, at this, municipal waste except the municipal waste of reality, also refer to industry, biological mud with other etc.The refuse amount constantly increases, and the capacity that unrestrictedly increases the landfill place is irrational at economic aspect.In addition, for example a large amount of environmentally harmful materials can discharge from refuse.Therefore be proved to be when handling, as far as possible effectively to utilize again a kind of significant method of the refuse that produces by the method for burning (incineration) processing refuse.Because related material is extremely impure, so incineration of waste just produces reluctant flue gas, and flue gas also can discharge some restrictions and/or make the material that is difficult to reclaim effectively the heat that produces in the burning process.
By in the burning disposal refuse process, the energy that produces in the burning process can be recovered in the heat transferring medium.But because the various materials that exist, for example chlorine-containing compound causes the danger of heat exchange surface corrosion, causes in the cooling of gas problem complicated.Just be absorbed in very difficult state when heat exchange surface contacts with the refrigerating gas that contains corrosive deposit, its durability may be very poor in this case.
Advised that the process that destroys municipal waste with burning carries out in utilizing the incinerator of fluidization.But fluidized combustion requires before burning refuse to be carried out preliminary treatment, and this is that refuse will grind enough carefully at least because when using fluidization.But this not enough under multiple situation, and for example refuse also must be classified before burning, and this is because the content and the size distribution of untreated refuse all may be very inhomogeneous.Equally, in the fluidized combustion process, because the cause flue gas maximum temperature of its feature reaches about 1000 ℃.When temperature was higher, the material of bed was for example fusible, and therefore perturbation operation, adopts the temperature that is lower than described temperature usually.
86471 suggestions of FI patent use fluid bed fluidized bed furnace (flui dized bedboiler) to handle refuse, and what burn in stove is the burning part (incineration fraction) that produces in independent refuse preprocessing process.The biological part (biological fraction) that obtains in same preprocessing process is because of processing forms methane, and advised utilizing biogas to improve the temperature of the exhaust gases passes behind the fluid bed fluidized bed furnace.According to above-mentioned patent, by carrying out the generation that this aftercombustion (afterburning) can reduce environmentally harmful polyaromatic.Above-mentioned aftercombustion with make the same exhaust gases passes behind the combustion chamber of steam superheating in carry out.
But in this device, problem is that chlorine compound causes that corrosion is dangerous in the flue gas, and is particularly all the more so when the overtemperature of steam improves.Almost always produce chlorine compound in the incineration of waste process, in fact, the existence of chlorine compound has stoped brings up to sufficiently high temperature on a certain predetermined temperature with overtemperature.
Incineration of waste also can be carried out in fire grate formula burning (grate incineration).Owing to can on fire grate, burn untreated refuse, so this is a kind of advantageous method.The rapid process of multistep that the preliminary treatment of refuse is normally complicated, thus fully not this process the fire grate formula is burned have tangible advantage at economic aspect than fluidized combustion.In the fire grate formula was burned, temperature even can bring up to 1200 ℃ had so just guaranteed effective burning.But, in this case, because flue gas also contains the corrosion compound, chlorine for example, so only burn by the fire grate formula, the overtemperature of steam can not be brought up to about more than 400 ℃, can not bring up to 300-420 ℃ more accurately, this is because the corrosion of superheating surface will increase excessively, and the equipment processing safety reduces greatly.
In fact, burning is untreated the capacity of refuse, though fire grate formula incinerator is very flexible, in producing the superheated steam process, when bringing up to overtemperature more than 420 ℃, this device is impossible in known technical scope.
Therefore, the purpose of this invention is to provide a kind of simple but effective method of at high temperature handling the solid material of refuse and other, it is easy to use and the heat that produces in this process is mainly used in production steam.
The present invention also aims to provide fire grate formula to burn the method that reclaims heat, wherein compare, obtained the superheated steam of higher temperature with method with prior art with refuse.
The purpose of this invention is to provide a kind of method of at high temperature passing through the processing refuse of incinerating waste material on fire grate, form with superheated steam reclaims the heat that produces thus, and in the method, when being used to generate electricity, the generating efficiency of resulting device is higher than prior art.
The basic design of method of the present invention is: refuse can burn at high temperature by the fire grate formula and handle, Fu Za refuse preprocessing process is no longer necessary thus, but the heat that untreated basically refuse can be burned and produce can be used to produce hyperthermia and superheating steam, and hyperthermia and superheating steam can be further used for again for example generating electricity.
More particularly, the feature of the inventive method is that described method comprises following at least step: unpretreated solid material is added in the Burning Room for the treatment of solid material at high temperatures basically; Be higher than 1000 ℃ temperature and in the presence of oxygen-containing gas, heating or the burning solid material; So that flue gas infeeds recycle stock with the mode that recycle stock (circulating material) mixes effectively mutually, contact with the flue gas that produces; In this process, continue to transmit the mixture of flue gas and recycle stock, therefrom reclaim heat simultaneously; Separating cycle material from flue gas; Transmit flue gas with further processing; Be sent to cooling procedure with the recycle stock that will separate from flue gas, wherein the heat of recycle stock is used for improving the temperature of the steam that produces at fire grate formula incinerator.
According to a preferred embodiment of the present invention, can in burning process, carry out waste disposal, refuse wherein, for example municipal waste is burned by the fire grate formula, thus refuse can be unfiled basically and not be carried out any pretreated mode and burned.In addition, but the incineration temperature of the incineration of waste that maintenance bond was used.If desired, the process gas (process gas) that produces can be heated to the temperature more than 1000 ℃, even the temperature more than 1200 ℃, for example be used to destroy environmentally harmful compound, as chlorinated hydrocarbon.The process gas that produces in fire grate formula burning process contacts with recycle stock, and the latter absorbs at least a portion heat of flue gas and heats up simultaneously.The recycle stock that contacts with process gas mixes effectively mutually with process gas sends into a separator, and this separator is preferably cyclone separator.At least a portion solid material separates with process gas, and again by in the above-mentioned separated portions at least a portion being imported the cooling procedure of carrying out recycle stock in the cooler, this cooler is preferably fluidized bed cooler.If desired, the part of the recycle stock of separation can directly be returned technical process, and contacts with the gas that produced in the fire grate formula burning process.And another part of the recycle stock that separates can be discharged fully from technical process.
The separator of recycle stock is preferably cyclone separator, wherein produces effectively air whirl.Because the effect of described air whirl, can be with the air conditioning that adds to approaching very much stoichiometric number, this is because because effective immixture of cyclone separator, unburned material in the flue gas, mainly be that carbon monoxide contacts with unreacted oxygen effectively, therefore and can be owing to accurately having regulated combustion air, and reduced the unnecessary discharging that produces by airborne nitrogen, almost be retained in the flue gas simultaneously without any unburned oxygen.And because effectively immixture causes having taken place burning fully, so can shorten the body of heater after the fire grate formula burning process, this is because the separator behind the body of heater has guaranteed effectively and completely to burn.
In the cooler of recycle stock, heat-exchanger rig is set, is preferred for superheated steam.Treat that overheated steam preferably produces by being arranged in the steam raising plant that is connected with fire grate formula incinerator.The steam that imports the heat-exchanger rig of cooler can be by overheated (presuperheated) or saturated steam in advance.For cooler, the heating surface of intermediate superheating steam also can be set if desired, for example, if device is connected to two stage turbine.In cooler, recycle stock cooling, the simultaneously overheated steam that in heat-exchanger rig, flows.
According to a preferred embodiment of the present invention, when the cooler of recycle stock is the fluidized bed type cooler, the fluidized gas of recycle stock can be infeeded cooler, the heat-exchanger rig that is arranged in the steam superheater operation so promptly is in heat exchange with recycle stock and contacts.Like this, the heat in the recycle stock just can reclaim with the form that is higher than 420 ℃ hyperthermia and superheating steam, and does not have obvious corrosion danger on superheating surface.The fluidized gas that imports the recycle stock cooler can derive from fluidized bed cooler, for example, return body of heater again or return near the fire grate, as the incineration of waste process once, secondary or tertiary air.
Chilled recycle stock or return with flue gas that fire grate formula burning process produces contacts, or removes from technical process wholly or in part.Main improvement on prior art is, by utilizing method of the present invention, available fire grate formula burning process burns unpretreated refuse, and produces superheated steam simultaneously, and wherein the overtemperature of superheated steam can be higher than the overtemperature that the method with prior art obtains.By utilizing method of the present invention, vapor (steam) temperature even can bring up to 420-550 ℃, preferred 500-550 ℃, and on the superheating surface without any the danger of corrosion.Utilize this device, compared with prior art, can improve the temperature of superheated steam significantly.
By using the cooler of recycle stock, can be outside the technical process of reality, at corrosive fume that fire grate formula burning process produces in one's power outside the scope, the cool cycles material, thereby also make steam superheating simultaneously, thereby the condition in the external treatment device does not depend on the condition of actual waste treatment process, therefore the overtemperature of steam can be brought up to more than 420 ℃, even 420-550 ℃ temperature, preferred 500-550 ℃, because corrosive deposit that discharges in waste treatment process such as chlorine do not exist.In cooler (preferred fluidized bed cooler), can select the non-aggressive material as fluidized gas.Possible fluidized gas for example is a noble gas, as nitrogen, or if desired, also can use oxygen as fluidized gas.But air is the preferred fluidized gas of using.Will can improve in this way with the overheated vapor (steam) temperature of recycle stock, and the do not corrode heating surface danger of (for example because chlorine).
