Detailed description of the invention

The utility model is described in further detail below in conjunction with the accompanying drawings:

A kind of vertical pyrolysis gasification furnace, including feed mechanism 10, tapping mechanism 9, described Vertical Heat is vented one's spleen

Change and be evenly arranged several mozzles 11 avoiding pyrolysis gas Airflow obstruction on the inboard wall of furnace body of stove, described mozzle 11 connects formation backflow with water leg 12, described vertical pyrolysis gasification furnace also includes sealing mechanism, working region and rabbling mechanism, described sealing mechanism includes first hermatic door the 1, second hermatic door 2, the second described hermatic door 2 is arranged on V-type prominence, body of heater upper end, and described first hermatic door 1 can not be opened with the second hermatic door 2 simultaneously;Described working region includes dry section 4, pyrolytic gasification district 5, combustion zone 6, the body of heater of described dry section 4 upper end being provided with exhaust opening 3;Described rabbling mechanism includes slag pan 7 and spice dish 14, described goes out slag pan 7 and spice dish 14 is arranged in same rotating shaft, be provided with in described rotating shaft communicate with the external world for hollow structure.

Further, described pyrolysis gasification furnace also includes combustion-supporting mechanism 13, and described combustion-supporting mechanism 13 is made up of oil tank, oil pump and burner;The energization solenoid 15 of absorption magnetic metal material it is provided with on described feed mechanism 10 4 wall;Being provided with double roller feeder between described second hermatic door 2 and dry section 4, the gap between two rollers can adjust;Described pyrolytic gasification district 5 uses the inverted round table shape and structure that footpath mouth is tapered.

The described slag pan 7 that goes out is arranged on bottom combustion zone 6, and described spice dish 14 is arranged on pyrolytic gasification district 5

Middle part, described goes out slag pan 7 and spice dish 14 is all beveled structure, goes out slag pan 7 and spice dish 14 upper surface is additionally provided with convex teeth portion.This utility model mozzle 11 connects formation backflow with water leg 12, extend its service life, this temperature that will result in outside is too low, and the temperature drift at center, thus have impact on the response time, this utility model installs a spice dish 14 rotated additional in pyrolytic gasification district 5, relies on the effect of centrifugal force to enable the rubbish outer wall motion of inside, rely on the gravity of rubbish self simultaneously, enable the rubbish on top to move to bottom.

The first described hermatic door 1 and the second hermatic door 2 are interlocks, are i.e. only in closedown when upper strata door

State time, lower floor door just could be opened;The second described hermatic door 2 uses smoke exhaust fire damper or butterfly valve structure to make, and the first hermatic door 1 is closed when producing electric signal, and the second hermatic door 2 is opened.Owing to pyrolytic gasification is carried out under reducing atmosphere, therefore, it should be noted that prevent the infiltration of air when charging.This utility model have employed two-door structure.When charging, the second hermatic door 2 is closed, and the first hermatic door 1 is opened, and after upper strata hopper filled by rubbish, the first hermatic door 1 is automatically switched off, and the second hermatic door 2 automatically turns on, and rubbish falls under gravity into working region.

By ASMESEC II (boiler and pressure vessel code), the body of heater of this utility model pyrolysis gasification furnace uses SA387Gr11CL2 heat resisting steel, because the existence of Gr, Mo element, improve elevated temperature strength and creep rupture strength that steel works at a temperature of higher than 350 DEG C, this material also has good resistant to hydrogen corrosive power simultaneously.In all of chrome-molybdenum steel, the toughness of SA387Gr11CL2 sheet material, intensity, welding performance are relatively good, so the case material as reative cell uses.

A kind of household-garbage processing process using vertical pyrolysis gasification furnace, comprise the steps: that charging-vertical pyrolysis gasification furnace pyrolytic gasification-second-time burning-waste heat recovery-chilling deacidification-bag-type dust-detection enters air, combustion air is heated to about 200-300 DEG C by air cooler and is re-fed into vertical pyrolysis gasification furnace by the flue gas part after described waste heat recovery, to reduce combustion-supporting oilconsumption.

When being embodied as, enter the flue gas drying that first rubbish of pyrolysis gasification furnace risen by dry section 4, moisture evaporation therein in dryer section;Being decomposed into the combustible such as carbon monoxide, gaseous hydrocarbons in pyrolytic gasification district 5 and form mixed flue gas, mixed flue gas is inhaled into dual firing chamber's burning.

Residue after pyrolytic gasification (inorganic dirt that tar liquid, purer carbon element and rubbish itself contain and inert substance etc.) sinks to combustion zone 6 and fully burns, temperature is up to 1100-1300 DEG C, and its heat is used for providing energy needed for dry section 4, pyrolytic gasification district 5.Combustion zone 6 burn after the coking shape residue mechanical presses through going out slag pan 7, the block that is broken into below 100mm be expelled in the water sealed tank of furnace bottom, discharge through wet type slag-tapping system.

The hollow structure going out slag pan 7 is connected with air cooler by blower fan, on the one hand cools down the coking shape residue after burning, moreover it is possible to provide sufficient combustion-supporting oxygen to combustion zone 6.Air goes upward to pyrolytic gasification district 5 after combustion zone 6 consumes a large amount of oxygen, and defines the oxygen debt or anoxia condition that pyrolytic gasification reaction occurs.

The mixed flue gas that pyrolysis gasification furnace produces enters dual firing chamber by exhaust opening 3, through secondary wind oxygenating, fully burning, in-furnace temperature controls more than 850 DEG C, high-temperature flue gas after burning temperature after the energy is reclaimed in fire tube heat recovery steam generator heat absorption is down to 600 DEG C, combustion air is heated to about 200-300 DEG C by air cooler and is re-fed into vertical pyrolysis gasification furnace by a part, another part enters chilling tower water-spraying control to 200 DEG C, jet respectively activated carbon, sodium ascorbyl phosphate, activated carbon has bigger serface, the dioxin in flue gas and heavy metal can be adsorbed, and sodium ascorbyl phosphate and smoke contacts react, the oxysulfide in flue gas can be reduced, the stripping quantity of the pollutant such as hydrogen chloride, last flue gas enters sack cleaner, dust removal by filtration, air is entered after the most up to standard.

The technique that this utility model is used destroys clearance by fire>99%, dioxin concentration<0.1TEGng/Nm3

Above-described embodiment of the present utility model; only clearly demonstrate the citing that this utility model is done; but being not limited to protection domain of the present utility model, the technical scheme of all equivalents falls within category of the present utility model, and scope of patent protection of the present utility model should be limited by each claim.
