Description
The utility model content belongs to the equipment in the clean comprehensive utilization of energy field, relates to a kind of polynary slurry vapourizing furnace.
Industrialized various airflow bed gasification furnace is that the mode of raw material, pure oxygen gasification is in the majority with coal water slurry or dry coal powder, and the type of furnace is for to constitute full hot wall stove and two kinds of structures of the full cold hearth of water-cooled wall type with refractory materials.In these two kinds of secular application processes of the type of furnace, exposed more equipment and technology problem, concerning full hot wall stove, service temperature is up to 1350～1500 ℃, the molten slag that produces has produced serious erosion to refractory materials and chiller and has washed away, vapourizing furnace such as refractory materials, chiller internals are shorter work-ing life, usually cause vapourizing furnace runtime short, and with the generation of the dangerous factor of production; For full water cooling wall vapourizing furnace, because heat dissipation capacity is big, liquid slag very easily Quench is solidified, and produces problems such as dross and slag block up in the stove.The Quench of the high-temperature gas of outlet of still adopts chilling ring Quench mode, and the chilled water aperture of chilling ring is easily stifled in the use, is often burnt out, and faults such as the uniform distribution control difficulty of chilled water cause vapourizing furnace to stop.The slag tap mode of airflow bed gasification furnace not only produces serious erosion to stove inner members such as refractory materials and chillers and washes away, and with the generation of piece slag, and dreg removing system is standing to be put dregs breaker and guarantee that deslagging is unimpeded.All these problems affect the cycle of operation of gasified boiler system, restricted the Economic development of enterprise.
The purpose of this utility model is intended to overcome the deficiency of existing installation technology, proposes a kind of rational in infrastructurely, and raw material sources are extensive, can use oxygen enrichment to make vaporized chemical, easy handling, and the cycle of operation is long, the polynary slurry vapourizing furnace of long service life.
For realizing the purpose of foregoing invention, the technical solution of employing is such: coil tube type water-cooled parietal layer is set, the polynary material of compound composition between the refractory materials of A. vapourizing furnace liner and the lagging material
Half water wall structure of slurry vapourizing furnace.B. chiller is designed to overflow type, increases the service life.C. be raw material with the polynary slurry, realize the raw material sources variation; With the oxygen enrichment is oxygenant, can reduce the investment of oxygenerator.D. the vapourizing furnace service temperature is 1100～1450 ℃, reduces the oxygen consumption, and the lime-ash of generation is discharged with solid-state form.
Compare with existing technology; innovative point of the present utility model and advantage show: the half water-cooled wall-like structure that A. polynary slurry vapourizing furnace adopts; can effectively reduce the temperature of refractory materials; the protection refractory materials is avoided the erosion of high-temperature gas; reclaim heat simultaneously, improved the heat energy utilization rate of vapourizing furnace.B. the chiller of vapourizing furnace adopts the overflow type structure, and design specifications is reasonable, long service life.C. this vapourizing furnace is raw material with the polynary slurry, realizes the variation of raw material sources, optimizes the configuration of resources, and carries out the change of raw material route easily, and the oxygen enrichment with 60～98% is a vaporized chemical, and supporting available pressure swing adsorption oxygen making device is invested less.D. vapourizing furnace is operated under 1100～1450 ℃ temperature, and temperature is moderate, and the oxygen consumption is low, and no slag produces, and has avoided the erosion of molten slag to stove inner members such as refractory materials and chillers.Its solid lime-ash is entrained with reaction zone by air-flow easily, and it is stifled can not form slag in vapourizing furnace, makes deslagging more unimpeded, because gasification temperature is suitable, and the protection of vapourizing furnace half water-cooled wall-like structure in addition, the long service life of its flame retardant coating and chiller.
Raw material of the present utility model is a polynary slurry, it is characterized in that forming by solid fuel materials more than three kinds or three kinds wherein such as oil (perhaps water), refinery coke, petroleum pitch and coals, its solid-fuelled content 〉=50%, add certain tensio-active agent, can improve pulp density and stability.Form the raw material of slip and can optimize necessary resources easily, reasonably fully utilize local resources.
In conjunction with the accompanying drawings the utility model content is described further.
Referring to accompanying drawing, the polynary slurry vapourizing furnace is a upright cylinder, and the top is an elipse head, and the bottom is the cone end socket, is provided with coil tube type water-cooled parietal layer (5) between refractory materials of liner (6) and the lagging material (4), has constituted half water wall structure of vapourizing furnace.This structure has been drawn the advantage of full hot wall stove and full cold hearth, to protection refractory materials better effects if, and has reclaimed heat in the mode of byproduct steam.The import of polynary slurry and oxygen enrichment (7) is positioned at the top of vapourizing furnace, its midperpendicular overlaps with the cylindrical shell axis of vapourizing furnace, overflow type chiller (3) is between vapourizing furnace reaction zone and bottom water-bath, be intended to cooling down high-temperature gas, make lime-ash wetting, lime-ash separates in water-bath with gas, and lime-ash is discharged vapourizing furnace together with chilled water, and the gas of rough purification leaves vapourizing furnace by outlet (8).Sequence number 2 is the import of vapourizing furnace chilled water among the figure.
