Description
The present invention relates to a kind of vitrifying and power generation system of being used for.The present invention particularly advantageously is applicable to vitreous toxic waste and the system that uses waste oil to act as a fuel.When furnace charge not with waste material during as its raw material, the present invention is equally applicable to the general gas furnace operating.
Various glass melting furnaces are arranged, and many kinds wherein all are applicable to the poisonous widely feedstock production glass of employing.In order when keeping the glass work output, to be suitable for raw material widely, offer the amount of the fuel gas or the oil of stove by change, will change condition in the stove.
Be shaped and fusion cast glass, need make glass reach 1350 ℃ temperature range.In order to realize this temperature, effluent gas temperature must be in about 1550 ℃ of temperature.Because temperature is high like this, the energy when stack gas is left stove is very high.Therefore, glass industry is being repaid examination always and is being come the recovery part heat by using accumulation of heat or heat exchange air preheating system.In this case, stack gas will be passed through a regenerator, and general regenerator comprises two chambers that are made of refractory brick, the air that the chamber heating is sent here, and it will be admitted in the stove, and the hot flue gases of stove is left in another chamber cooling.Because flowing through this chamber, stack gas can make the brick heating, so periodically open these chambers.When in a single day the temperature of brick reaches predetermined temperature, will change through the flow of this regenerator, make be input to this chamber be used for incendiary gas by hot brick preheating.When this process was carried out, second regenerator was used for removing heat from stove discharge gas.Passage by these two regenerator replaces continuously.Generally, the air preheating temperature value and is in 1450-1550 ℃ in the temperature of the stack gas on the top of regenerator between 1200-1300 ℃.Even air preheating temperature is so high, the temperature of leaving the stack gas of regenerator also is in the 450-600 ℃ of scope.This is equivalent to about 25% of the input of fuel energy in the stack gas.Why such reason be the thermal capacitance flux of fuel gas and this air under these temperature ratio more than 1.2: 1, this efficient that limits any regenerator is about 70 or 80%.
The interchanger that number of different types is arranged.Wherein a kind of interchanger is a metal construction, and it also can be built with refractory materials.In this interchanger, the waste gas of heat by flue, is equipped with metal or fire resisting material tube continuously in this flue.Air and waste gas adverse current are passed through this pipe continuously, thereby make its preheating.
Preheating 650-700 ℃ technological specification is that the temperature of combustion gas is 950-1050 ℃.So can see that this interchanger is effective not as regenerator.Therefore, they can not be widely used for the recovery of heat in the glass industry.
In order to guarantee that this heat do not lose, the energy in flue gases of furnace can be used for heating raw, heating boiler or is used for other Waste Heat Recovery System (WHRS), and this system is not connected with glass furnace.
Unfortunately, stack gas is used for the preheating furnace charge, normally stack gas is directly contacted with raw material, make that the water in raw material is discharged to chimney with hot flue gases along its passage.Yet when containing foxic waste in raw material, organic toxin also can be discharged with water.And international law stipulates any poisonous gas and all will it be disappeared destroys being exposed under the high temperature (its temperature is at least 1200 ℃) the one given period (this time was greater than for 2 seconds) under the excess of oxygen existence condition, and this just means that this selection was unacceptable when foxic waste was a part of in the furnace charge.
One of method of utilizing this energy is to come heating boiler with it.This boiler can be used to produce steam, generates electricity with driving steam turbine.Although the multipotency of common glass furnace produces the power of 1.5MW, it can prove and be difficult to use a common glass furnace that the output of one constant power is provided probably.If this energy will be effectively utilized, the power that produces by this equipment need be constant and predictable so.
Problem has occurred in the time will increasing the output of this boiler.The temperature that can raise in its kiln is conditional, because the refractory lining of the too high kiln of temperature can be damaged.The stack gas of similarly, discharging from stove is as if can not directly sending into boiler in the operating temperature range that is not reduced to the boiler permission.For example, for some stack gas, boiler can not be operated being higher than under 1200 ℃ the temperature.Then all the more so when containing volatile heavy metal and sour gas in the gas.If more gas is provided, promptly offer the gas of fuel by increase, then reduced the temperature in the kiln thus, this means from the gas gross of boiler output to increase equally.Yet, importantly will keep minimum from the gas volume of boiler feeding, because all such gases must be handled, to remove any remaining toxin, this toxin is not removed in vitreous.
Related equipment and technology is very expensive when handling such gas, is very important so handle the gas of minimum.
Up to now, proved that it is impossible wanting these three prerequisites of balance, that is:
(ⅰ) to from kiln, prepare the glass of maximum production;
(ⅱ) to from boiler, produce the power of predetermined constant amount; And
(ⅲ) to from boiler, produce the stack gas of minimum.
According to the present invention, a kind of vitreous and power generation equipment are provided, comprising:
One forming of glass kiln, comprising material inlet and gas feed, this gas comprises fuel gas or oil and preheated air and is used for feeding the kiln flue gas outlet;
Heat reclamation device, furnace flue gas install its temperature through this to be reduced, and this heat reclamation device also preheating is sent into the air of kiln; With
A boiler that links to each other with heat reclamation device comprising gas feed, is admitted to boiler by its furnace flue gas, and vapour outlet and pneumatic outlet are sent by this exhaust pass gas, and the stack gas of boiler is sent to a gas treating system;
Wherein boiler flue outlet and two outlet streams link to each other with the device that is used to be divided into two streams, make a stream that boiler flue is delivered to gas treating system, import, the outlet of kiln or the import of boiler of second stream guiding kiln, thus make the part of the stack gas of boiler form recirculation.
According to method of the present invention, its step comprises: feeding glass forms furnace charge, fuel gas or oil and preheating gas; Through heat reclamation device furnace flue gas (temperature of stack gas reduces in this device) is sent in the boiler, produce steam herein and export boiler flue, this vaporizer stack gas is sent to an air treatment system, thus, the recirculation of part boiler flue is entered the import of kiln import, kiln outlet or this boiler.
Take a part of boiler flue from the exit away, can reduce total volume of air of sending into gas treating system like this, and can reduce the cost of final gas processing thus.
If stack gas is sent into the kiln import, then increased the volume of air of sending into by kiln, this means that the air capacity that needs to add in the fuel gas may reduce.So just reduced the total air of sending in the system.
On the other hand, the stack gas of boiler is recycled to the kiln outlet, so that it can mix with the furnace flue gas phase before entering regenerator.In addition, also can when leaving regenerator, the boiler inlet place be admitted to furnace flue gas at it.
Separate a part of air-flow from boiler export and leave air handling feeding stream, thereby reduce the amount that to handle air.
Though first and second aspects of the present invention can independently be used, such system is dumb, and can not use kiln raw material widely.
The 3rd aspect of the present invention is that first and second aspects of the present invention are combined, wherein that part of in the glass handling will be sent in the stack gas of boiler, separated into two parts, a part is directly delivered to the import of kiln, and second section is delivered to the import of boiler.This system can be used for the part air-flow is introduced the kiln import, will partly introduce boiler inlet simultaneously.Yet, an on-off mechanism is preferably arranged, it is arranged at carries out switch between these streams.An efficient system so just is provided, thereby for example, in 1000 tons of glass of preparation, has produced the power of 36MW, and do not produce too much waste gas.
Boiler can be the water pipe type, also can be fire-tube type, and this depends on the size and the power of system.
Heat reclamation device can be common regenerator or interchanger, but preferably regenerator is uncurrent, and brick that need not effective volume in this regenerator seals, and would rather only use a spot of brick, so that a spot of heat of recovery from the stack gas of kiln only.Have additional benefit like this, guaranteed in all time waste gas is required regulation in 2 seconds of temperature maintenance more than 1200 ℃ without the regenerator of brick sealing.
Should be noted that usually the most effective heat exchange is to be that 3.3 times of kiln transverse section are realized by the volume that brick is provided.Yet for efficient system so too, brick will be drawn too many heat, and this will make the air themperature Tai Gao of preheating-too high for kiln.Therefore, be that this regenerator will be less than preferably effective volume with the meaning of the brick of " on a small quantity ".
According to all four aspects of the present invention, the example of vitreous and generation power system describes with reference now to accompanying drawing:
