Embodiment
Below in conjunction with accompanying drawing, be described further with other technical characterictic and advantage with regard to the utility model is above-mentioned.
See also Fig. 1, be the one-piece construction figure of vapourizing furnace described in the utility model.The vapourizing furnace type that the utility model is considered, the reaction zone that mainly comprises the water wall coil pipe pressure-bearing shell formation that contains the high temperature resistant lining material of coating, the carbonaceous material that drops into is under the effect of vaporized chemical, partial oxidation reaction takes place generate synthetic gas, carbonaceous material that part is not oxidized and the inorganic oxide in the raw material at high temperature form the lime-ash of molten state.
As shown in Figure 1, vapourizing furnace 01 mainly is made up of reaction zone 8, trunnion 6, chill zone 2 and bottom water-bath 1.Contain vaporized chemical in the reaction zone 8, for carbonaceous material part oxidation therein, the heat that comprises synthetic gas with generation goes out product.The lower end of reaction zone 8 is provided with at the bottom of the intilted awl 7, importing trunnion 6 downwards will react the high-temperature synthesis gas and the molten state lime-ash that generate.
The function of trunnion 6 is that high-temperature synthesis gas and molten state lime-ash water conservancy diversion are entered chill zone 2 downwards, makes it lower the temperature before discharging chill zone and separate.
Chill zone 2 comprises a downtake 4, and it is positioned at the below of trunnion 6, and spaced apart with trunnion 6, with high-temperature synthesis gas and molten state lime-ash guiding below, enters the water-bath cooling and separates.6 of downtake 4 and trunnions are provided with chilling ring 5, and its effect is to be sprayed to the inwall of downtake 4 by the external chilled water of vapourizing furnace, with protect its with high-temperature synthesis gas be not damaged after the molten state lime-ash contacts.
Through the synthetic gas after the Quench, can carry a certain amount of particulate matter under normal conditions and discharge by vapourizing furnace outlet 9, enter lower procedure and further process.The molten state lime-ash that enters bottom water-bath 1 is deposited on the chill zone bottom because of action of gravity descends gradually, the lime-ash after collecting will regularly be discharged vapourizing furnace.
Trunnion 6 connects to form continuous structure with the awl end 7, downtake 4 and chilling ring 5, rounding off is all adopted in the each several part junction, so that reduce the caused wearing and tearing of molten state lime-ash of temperature flowing, each several part is again relatively independent parts simultaneously, in the present embodiment, above-mentioned four parts are positioned on the central shaft of basically identical.
Please continue to consult Fig. 2, be the structural representation of the vapourizing furnace trunnion that the utility model proposes.As shown in Figure 2, vapourizing furnace trunnion 6 of the present utility model mainly is made up of round shape cinder notch coil pipe 63, tapered water conservancy diversion coil pipe 62 and round shape water conservancy diversion coil pipe 61, these three parts vertically are arranged in order along the vapourizing furnace axis, and right alignment all need satisfy concrete design requirements.Be equipped with parallel or staggered cylinder or rectangle column anchor nails in the inboard of round shape cinder notch coil pipe 63, tapered water conservancy diversion coil pipe 62 (contact high-temperature synthesis gas and molten state lime-ash side), be used for fixing certain thickness high temperature material; And round shape water conservancy diversion coil pipe 61 can be provided with parallel or staggered cylinder or rectangle column anchor nails, also can adopt and not establish the anchor nails structure, also be that round shape water conservancy diversion coil pipe 61 can adopt and lays the high temperature material structure, also can adopt and not lay the high temperature material structure.
Form in the each several part coil pipe of trunnion, preferably carry out pump circulation as heat-eliminating medium with water, the arrangement of trunnion is in order to high-temperature synthesis gas and molten state lime-ash are directly imported bottom water-bath 1, water-bath flow herein must be monitored, and has suitable water to remain in the water-bath 1 of bottom in cooling, sepn process to guarantee synthetic gas and molten state lime-ash.The round-robin heat-eliminating medium can be that single-stage also can be designed as multistage circulation in parallel respectively in round shape cinder notch coil pipe 63, tapered water conservancy diversion coil pipe 62 and round shape water conservancy diversion coil pipe 61, heat-eliminating medium enters each assembly by the collecting tubule distribution in the trunnion outside, and after circulation, also import in another group collecting tubule, the collecting tubule pressure reduction of turnover heat-eliminating medium also should be monitored.
When high-temperature fusion attitude lime-ash after the reaction zone awl enters round shape cinder notch coil pipe 63 in the end 7, because the inboard side towards the fire temperature of cinder notch coil pipe is far below high-temperature fusion attitude ash temperature under the heat-eliminating medium effect of pump circulation, therefore the molten state lime-ash that contacts with round shape cinder notch coil pipe 63 cools off fast, mobile forfeiture rapidly, form solid-state slag blanket, along with the cindery continuous accumulation of molten state, solid-state slag blanket progressive additive surface temperature also increases gradually, when the cindery temperature of molten state reduces the gradient deficiency so that during the lime-ash lost flowability, the solid slag layer thickness no longer increases, this process takes place downwards gradually along the side towards the fire of trunnion 6 inboards, final solid-state slag blanket will cover trunnion 6 whole side towards the fire, follow-up high-temperature fusion attitude lime-ash promptly flows at the solid slag laminar surface, also will no longer produce wearing and tearing to trunnion 6.The high temperature material that is covered in trunnion 6 inboard side towards the fire has completely cut off solid-state slag blanket and metal coil pipe effectively, has avoided high-temperature fusion attitude lime-ash directly to contact with coil pipe, has both alleviated the thermal shock impact and has also avoided the erosion of corrosive goods confrontation coil pipe in the lime-ash.
After high-temperature synthesis gas entered tapered water conservancy diversion coil pipe 62 through round shape cinder notch coil pipe 63, along with the progressively expansion gas speed of taper water conservancy diversion coil pipe 62 diameters reduces gradually, owing to enlarged the area that contacts with water-bath, cooling-down effect was strengthened simultaneously; On the other hand because the shape of tapered water conservancy diversion coil pipe 62, directly fallen into after by round shape cinder notch coil pipe 63 in the water-bath 1 of bottom by a part in the dirty high-temperature fusion attitude lime-ash of gravity separates with synthetic gas, another part is then dirty along taper water conservancy diversion coil pipe 62 and round shape water conservancy diversion coil pipe 61 wall that warms oneself in front of a fire, thereby reduced the possibility that chilling ring 5 and downtake 4 are subjected to the thermal shocking of high-temperature fusion attitude lime-ash, effectively prolong the work-ing life of chilling ring 5 and downtake 4, guaranteed the steady running of vapourizing furnace.
More than explanation is just illustrative for the utility model; and it is nonrestrictive; those of ordinary skills understand; under the situation of the spirit and scope that do not break away from following claims and limited; can make many modifications; change, or equivalence, but all will fall in the protection domain of the present utility model.
