Description
Technical field
The utility model relates to Coal Gasification Technology fields, and in particular to a kind of synthesis gas heat recovering device, and it is a kind of
Gasification furnace including the recyclable device.
Background technique
With the gasification of the carbon raw materials such as the biomass fuels such as the fossil fuel such as coal, petroleum coke, straw or house refuse
Technology, main purpose are the changes for making the chemical energy in carbon raw material be partially converted into produced gas (commonly referred to as synthesis gas)
Learn can, using as fuel carry out using；Or CO and H is made in carbon raw material2, raw material as subsequent technique.Such as, make to contain
Carbon fuel occurs imperfect combustion with gasifying agent at high temperature and reacts, and carbon, protium are largely converted into CO, H in fuel2For
Main synthesis gas, the chemical energy in carbon raw material is there are about the chemical energy that 80% has switched to synthesis gas in the process, and about 20% turn
The sensible heat of synthesis gas and lime-ash is turned to.It is gasification synthesis gas Exposure degree by the technology that this about 20% sensible heat recycles
Technology, the method that heat exchanger is usually used are translated into the sensible heat or latent heat of vapor, are further used for dynamic power, are situated between
Matter heating etc..
The synthesis gas that gasification generates has the characteristics that temperature is high, big containing the grey quantity of slag.Especially with the extensive of coal resources
It uses, the coal being suitble to for current gasification technology becomes that supply falls short of demand, anthracite and gasification reactivity with more high ash melting point
Low petroleum coke it is contour containing carbon resource using extremely urgent, and the gasification condition of this kind of carbon raw material is more harsh, such as gasifies
Temperature is higher, therefore proposes to heat recovering device more harsh.By taking high pressure dried coal powder entrained flow bed gasification technology as an example, gasification
The synthesis gas temperature of generation is generally 1200-1600 DEG C, is 20-200g/Nm containing the grey quantity of slag3, lime-ash is molten under high temperature
State is bonded in heat exchange wall surface easily to which heat exchange efficiency be greatly reduced, therefore to the most urgent of gasification synthesis gas heat recovering device
It highly necessary asks in terms of being presented as the fouling and slagging for reducing heating surface and improving heat exchange efficiency two.
Such as in the prior art, U.S. patent documents US4377132 (Texaco Development Corporation, " Synthesis gas
Cooler and waste heat boiler ") disclose a kind of syngas cooler of inside and outside Dual-drum, high-temperature gasification synthesis
Gas and lime-ash are directly entered cooler inner cylinder, and turn back in inner cylinder lower part into the annular space between inner cylinder and outer cylinder, with water cooling
Wall carries out heat exchange.But high-temperature gasification synthesis gas directly contact water-cooling wall will lead to lime-ash on the wall surface of annular space glue
Knot.
The problem of in order to alleviate lime-ash bonding, there is the side to cool down using water spray to high-temperature synthesis gas in the prior art
Formula.Synthesis gas and ash as disclosed a kind of method for producing synthesis gas in Chinese patent literature CN1923975B, in this method
The mixture of slag be introduced into quenching area, 700-1100 DEG C is quenched under the action of nozzle spray, then enter back into waste heat kettle into
Row heat exchange, so that cooling lime-ash will not be adhered to heat-transfer surface.The disclosed synthesis of Chinese patent literature CN101161792A
In gas heat recovery technique, then it is to export to spray into level-one chilled water in gasification zone, cools down synthesis gas uniformly and quickly with slag
To ash fusion point T1 hereinafter, then entering back into fire-tube type steam generator carries out heat recovery.Chinese patent literature
CN102213409A discloses a kind of recycling of sensible heat, is subtracted in internal layer water-cooling wall and the annular space arrangement water spray of outer layer water-cooling wall
Warm device, when internal layer water-cooling wall heat transfer deterioration, water spray reduces synthesis gas and ash temperature to reduce the dust stratification of annular space.
It is above-mentioned in the prior art by carrying out water-cooled cooling to high-temperature synthesis gas, so that lime-ash cooling loses viscosity, from
Without being easily adhered on heating surface, wall surface slagging is solved the problems, such as.But problem brought by this mode is, because of synthesis
The temperature of gas is lowered, thus the radiation heat transfer ability of synthesis gas can also decline to a great extent therewith.The hot-fluid of known radiation heat transfer is close
Degree is directly proportional to the biquadratic of gas temperature, then roughly estimating, gas temperature is reduced to 1100 DEG C from 1500 DEG C, and radiation is changed
The heat flow density of heat can fall to original 35%.As it can be seen that heat exchange of this method in order to cool down lime-ash, in radiation heat transfer room
Biggish sacrifice is made that in terms of efficiency.
Therefore, how under the premise of reducing heat exchange efficiency loss as far as possible to solve the problems, such as wall surface slagging, this is
One technological difficulties in field.In the prior art, Chinese patent literature CN101821365A discloses a kind of gasification cooling system,
The system is by tangentially spraying into gas into heat exchanger channels, so that high-temperature synthesis gas flows in a ring in annular heat exchange wall,
And by parameters such as flow rate, the vibration frequencies of control spout fluid, synthesis gas is made more uniformly to be distributed to mention in heat pipeline
High heat exchange efficiency；It also uses the mode of acoustic vibration to increase disturbance to enhance heat exchange simultaneously.Cooling system in the patent is logical
It is too strong to be combined to flowing of the gas on heat-transfer surface to achieve the purpose that enhanced heat exchange, enhance the heat convection on heat-transfer surface.But thing
In reality, at high temperature, the intensity of radiation heat transfer is much higher than heat convection, therefore the promotion ten of this heat-exchange system exchange thermal efficiency
Divide limited.And synthesis gas heat exchange efficiency how is further increased, this is the still unsolved problem in this field.
