The specific embodiment

Clearer for technical problem, technical scheme and beneficial effect that the utility model is solved, below in conjunction with accompanying drawing and embodiment, the utility model is further described.Should be appreciated that embodiment described herein is only for explaining the utility model, and be not used in restriction the utility model.

As Figure 1-3, the compound refuse pyrolysis melting furnace of a kind of vertical shaft, comprise the body of heater 1 of vertical coaxial structure, in body of heater 1, be provided with the dual firing chamber 3 of main combustion chamber 2 and main combustion chamber 2 outsides, main combustion chamber 2 is horizontal complex coaxial structure with dual firing chamber 3, between it, be provided with ring-type burning melting burner hearth 4, when the flue gas of main combustion chamber 2 is when entering dual firing chamber 3, flue-gas temperature can not decline, effectively avoided hot loss of energy in flue gas, make heat energy be concentrated and make full use of, be conducive to burn the stable of melting burner hearth 4 and dual firing chamber's 3 temperature; Do not add auxiliary fuel when carrying out the incineration disposal of house refuse advantage and basic guarantee are provided.

Interior high-temperature fusion wall 5 and the rotary fire grate 6 of arranging of burner hearth 4, links up the calorifics space of two combustion chambers effectively, takes full advantage of thermal-radiating principle, effectively improve temperature in stove, during operation, do not need to add auxiliary fuel, can be up to standard by refuse spontaneous combustion, greatly reduce operating cost.

The bell 7 at body of heater 1 top is provided with shaftless helical feed blanking device 8, and bottom is provided with slag removal mechanism 9, and the outside of body of heater 1 is provided with the drive unit 10 of rotary fire grate.

Dual firing chamber 3 is provided with labyrinth flue 11, labyrinth flue 11 arranges the flame hole 12 of multiple contractions, the immixture of strengthening Secondary Air and flue gas, make flue gas under the hot environment of >850 ℃, have the sufficient time to carry out oxidation fusion combustion reaction, guaranteed gas residence time >2S.Be conducive to the deposition of flying dust and flue dust in flue gas simultaneously.

The ignition temperature of dual firing chamber 3 is 1050 ℃ ± 50 ℃, and the temperature of floss hole is not less than 850 ℃, and gas residence time exceedes 2S, can interrupt the strand of bioxin, suppresses bioxin and generates.Meanwhile, also help the deposition of flying dust and flue dust in flue gas.

As shown in Figure 4, rotary fire grate 6 is with 360 ° of circle rotations, makes the slag burning enter uniformly slag removal mechanism 9.Also play the rotation tipping effect of the bed of material, further strengthen the burning of refuse simultaneously.Prior effect is also played the junk that makes to add in body of heater and is evenly distributed on burning zone, reaches the balance of body of heater heat and temperature.Meanwhile, rotary fire grate 6 also has the function of broken arch ventilation slagging-off.

Slag removal mechanism 9 comprises water seal scarfing cinder bucket 13 and is located at the scraper slagging machine 14 of water seal scarfing cinder bucket 13 lower ends, water seal scarfing cinder bucket 13 interior water are by cooling of furnace slag, the position that this mechanism is connected with body of heater 1 keeps stablizing good Butt sealing state, in whole slag removal, there is no dust and pollution, and convenient and swift Maintenance free again.

During work, rubbish drops in feed bin from body of heater top, and by shaftless helical feed blanking device 8, rubbish is continuously evenly added in stove.Along with the rotation of shaftless helical feed blanking device 8, add the junk in stove can evenly be sprinkling upon on any one surface on the interior circular section of burner hearth 4.Main combustion chamber 2 is followed successively by drying layer 15, pyrolytic layer 16, oxidation fusion burning zone 17, warm sludge layer 18, cold slag discharge layer 19 from top to bottom.The rubbish entering in stove can enter every aspect by from top to down, and air blast combustion air is sent into furnace bottom, can through cold slag, discharge layer from bottom to up, enter again warm sludge layer, in cooled slag, combustion air is heated, and the combustion air after heating is sent into oxidation fusion burning zone.Just entered in its top-down movement of rubbish of stove, be first subject to the effect of high temperature hot gas stream from bottom to top, can heat up rapidly, and evaporate moisture, be warmed up to 600 ℃, under the situation of anoxic, organic matter starts pyrolytic gasification melt-combustion.The pyrolysis gas producing is mixed into body of heater 3 with flue gas and steam from bottom to top.Along with the carrying out of dry thermal cracking, the temperature of rubbish raises step by step, and after organic substance pyrolysis, remaining carbon residue reaches after burning-point and burnt by bottom drum wind action, and now its top has again new rubbish to enter and above dropping on.The burning of these residue carbon residues provides thermal source to again the rubbish that has just entered stove, along with carbon residue burning is further violent, forms the gasification melt-combustion band of certain thickness aspect in stove, and the temperature of this melt-combustion band can reach 1100 ℃ of left and right.After this high-temperature fusion combustion zone, residue carbon residue and the complete after-flame melting of incendivity thing, the non-combustible materials such as remaining inorganic dirt also can be by while igneous fusion to 1100 ℃, fusing point all merges lower than the material of this temperature, the air stream that continues to rise with furnace bottom in moving down forms convection current, and air is heated, and residue dividend is cooling gradually, cooled residue becomes cellular, discharged by the attrition crushing of rotary fire grate 6 by scraper slagging machine 14.

The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all any modifications of doing within spirit of the present utility model and principle, replace and improvement etc. on an equal basis, within all should dropping on protection domain of the present utility model.
