A kind of high concentration salty organic waste liquid burning boiler

Technical field

This utility model relates to a kind of chemical industry, the high concentration salty organic waste liquid of paper industry carries out the environment protection energy-saving equipment of burning disposal and energy recovery, refers more particularly to a kind of high-concentration chemical industry organic waste liquid containing salt burning boiler.This utility model relates to a kind of chemical industry, oil refining, the high concentration salty organic waste liquid of paper industry carry out the environment protection energy-saving equipment of burning disposal and energy recovery, refers more particularly to a kind of high concentration salty organic waste liquid burning boiler.

Background technology

In recent years, fast development along with industries such as chemical industry, oil refining, papermaking, in its production process, often produce substantial amounts of high-concentration chemical industry salty organic waste liquid, these waste liquids are discharged in the Nature containing a large amount of non-biodegradable Organic substances and high concentration salty organic waste liquid, necessarily to environment, destroy ecological environment, infringement health, thus find a kind for the treatment of technology reasonable, effective, thus reduce the pollution to environment of this waste liquid, promote that industry value chain is significant.At present, industrial wastes processing method is mainly used biodegradation, method to deep under ground high-pressure injection and burning.The way of domestic usual employing burning disposal, burns toxic waste liquid by incinerator, makes waste liquid be decomposed into non-toxic gas in combustion, enter air.Why high concentration salty organic waste liquid burning boiler becomes the process difficult problem that environmental protection is burned, and also a major reason is: burn the alkaline metal salt containing a large amount of low melting points in the high-temperature flue gas generated.These materials all produce strong corrosiveness to furnace lining and heat-transfer surface, furnace lining can be caused to be burned or heating surface fouling and clogging, and cause system to be not normally functioning.

Analyzing after deliberation, the fusing point of pure sodium salt is at 801 DEG C-894 DEG C, but its fusing point to be reduced to 600 DEG C-750 DEG C under combinational environment, though fusing point following sodium salt bonding, under this state, sodium salt has fragility, and corresponding soot blower can be used to be removed.The melting temperature 600 DEG C-750 DEG C that the flue-gas temperature entering convection bank falls farther below sodium salt under combinational environment to this end, to try one's best just is conducive to boiler safety reliability service.

Patent CN103047659A proposes a kind of burning process processing high concentration salty organic waste liquid and burning boiler, including descending adiabatic furnace, multi-stage irradiation cooling chamber, convection heat-exchange chamber, soot blower, soda pop fairlead and drum, but the liquid waste incineration boiler described in this patent has the disadvantage in that (1) descending adiabatic furnace volume from top to bottom is excessive, for ensureing combustion temperature in hearth, a large amount of auxiliary fuel must be consumed, thus result in treatment cost of waste liquor and increase；(2) if arrange between descending adiabatic furnace and the first radiant cooling room by dry tablet number vertically with tilt deflector, this deflector easily cause vertically with tilt the molten state inorganic salt blocking that deflector is incinerated in rear flue gas, cause the equipment cannot be properly functioning.(3) block without smoke wall between descending adiabatic furnace and the first radiant cooling room, uncovered turn of descending adiabatic furnace is to the first radiant cooling room, due to heat radiation effect, the burning of descending adiabatic furnace is played negative effect by the first radiant cooling room, it is difficult to make the burning of descending adiabatic furnace to reach a high temperature burning stage, unless consumed a large amount of auxiliary fuel just can ensure that the incineration temperature of descending adiabatic furnace, if strengthening auxiliary fuel consumption, exhaust gas volumn is made again to increase, flue gas flow rate increases therewith, the most not only cause tail temperature too high, the most detrimentally flue gas flow rate increase causes flue gas to take away a large amount of fused salt to rear portion multi-stage irradiation cooling chamber, cause multi-stage irradiation cooling chamber salification serious, harm safe and reliable operation.If do not strengthen auxiliary fuel consumption will cause descending adiabatic furnace temperature of lower it is difficult to ensure that, slag tap difficulty, even result in slag-drip opening blocking cannot deslagging；(4) heating surface is not arranged in multi-stage irradiation cooling chamber, on the one hand due to the physical property feature of fused salt could be less in adhesiveness when the temperature of fused salt is well below the fusing point of fused salt solid granulates, but flue gas carries the most tiny fused salt granule, by on the furnace wall wall adhering to multi-stage irradiation cooling chamber what radiant cooling room especially front along journey, cause multi-stage irradiation cooling chamber heating surface pickup to affect radiation cooling effectiveness, and cause ash bucket bottom the blocking of multi-stage irradiation cooling chamber and multi-stage irradiation cooling chamber cannot normally work because fused salt blocking is tied.On the other hand the heating surface of fused salt pickup radiant cooling room causes radiant heat transfer to weaken, and reduces waste heat recovery efficiency, causes burning boiler bulky, increases construction investment；(5) this burning boiler only arranges the convection current tube panel of parallel baffled at low-temperature space, and heat-transfer effect is excessively poor, thus causes high fume temperature, and boiler thermal output is low.(6) on the right side of descending adiabatic furnace bottom, uncovered liquid state slag discharging device is set, this liquid state slag discharging device is difficult to reliability service, on the one hand the viscosity of fused salt is the least along with the viscosity of the highest fused salt of temperature when temperature is far above the fusing point of fused salt, but the temperature that this apparatus structure feature determines descending adiabatic furnace is difficult to the fusing point far above fused salt, so auxiliary fuel consumption must be strengthened when running could meet the requirement of slag tap with the temperature improving descending adiabatic furnace；The most uncovered liquid state slag discharging device is to atmospheric radiation heat exchange, and this process is very fast, causes fused salt easily to stick on the pipeline of liquid state slag discharging device because of cooling, starts local stoppages, and gradually wholly liquid state slag-draining device cannot be properly functioning.
