The utility model compact conformation, the combustion gasification reaction speed is fast, combustion gasification efficient and thermal efficiency height, the capacity reducing effect is obvious, uses clean and free from extraneous odour, and the dioxin discharging is extremely low, and fuel tolerance is strong.All kinds of to reduce the low calorie fuels environmental pollution, to tap a new source of energy and energy-saving and emission-reduction are that the purpose place all can be used.
Description of drawings
Fig. 1 is energy saving and environment friendly low calorie fuels treating apparatus structural representation.
Below in conjunction with accompanying drawing the utility model is further described.
The specific embodiment:
As shown in Figure 1, low calorie fuels treating apparatus body mainly comprises cylindrical combustion gasification chamber 3, circular all holes resistance slag plate 6, inversion type truncated cone-shaped slag trapping chamber 7 and 2 non-premixed type heat- storage type burners 2 and 5, charging aperture is arranged on the 3 roof face centers, combustion gasification chamber, 3 bottom surfaces, combustion gasification chamber and slag trapping chamber's 7 big underrun resistance slag plates 6 are connected, and slag-drip opening is arranged on the slag trapping chamber 7 handle face centers.The utility model chamber body can be divided into combustion gasification district, constant temperature resistance slag district and Ji Zhaqu. Burner 2 and 5 comprises spherical or cellular heat storage.The gas channel aperture is greater than 3mm, so that prevent liquid substance condensation block airflow passage when selecting cellular heat storage for use.Burner 2 and 5 is generally selecting for use, is arranged symmetrically on the sidewall of combustion gasification chamber 3, and two burner central axis are downward-sloping and prolong and intersect at resistance slag plate 6 central areas.Resistance slag plate 6 can be made up of the resistance slag plate in the even cloth of multilayer hole, and resistance slag plate heat storage performance is good, can constant combustion gasification chamber 3 temperature.Resistance slag plate 6 is drilled with cinder hole, and upper strata resistance slag plate cinder hole is big, and lower floor's material-blocking plate cinder hole is little, and the material-blocking plate cinder hole is staggered up and down.Melt cinder passes resistance slag plate 6 cinder holes and drops to slag trapping chamber 7.
The auxiliary equipment of utility model comprises that 4 combustion gas cut valve 1,4,8 and 9, empty combustion gas reversal valve 10 soon.Combustion gas is cut valve 1 and 4 soon and is installed in respectively on the outside gas pipeline, and combustion gas is cut valve 8 and 9 soon and is installed in respectively on the artificial fuel gas pipeline.Cut outside combustion gas that valve 2 sends into soon and import burner 2 Gas Pipe through combustion gas, cut outside combustion gas that valve 4 sends into soon and cut the part artificial fuel gas that valve 9 sends into soon through combustion gas and import burner 5 Gas Pipe through combustion gas through cutting the part artificial fuel gas that valve 8 sends into soon.
With the burning of right side tissue is example, and combustion gas is cut valve 4 and 9 soon and opened, and combustion gas is cut valve 1 and 8 soon and closed.Air enters burner 5 through empty combustion gas reversal valve 10, enters combustion gasification chamber 3 after passing heat storage and absorbing heat storage high temperature sensible heat.Strong gas-particle heat transfer takes place in the heat storage passage, and air themperature rises to rapidly more than 1000 ℃.In resistance slag plate 6 central area combustion gas, high temperature air with give birth to the reaction of flash combustion gasification through the low-calorific-value solid fuel hybrid concurrency of charging aperture vertical drop.High-temperature flue gas or artificial fuel gas are through left side burner 2 heat storages, and himself sensible heat is passed to heat storage rapidly, be cooled to and be higher than environment temperature 50-100 ℃ temperature levels, enter externally again through burner 2 and empty combustion gas reversal valve 10 back parts, remainder is cut valve 9 soon through combustion gas and is sent into left side burner 5 and act as a fuel.Along with the combustion gasification reaction is carried out, right side burner 5 regenerator temperatures reduce gradually so that air preheat less than 800 ℃, left side burner 2 regenerator temperatures are elevated to more than 1000 ℃ gradually, these space-time combustion gas reversal valve 10 actions, combustion gas is cut valve 4 and 9 soon and is closed, combustion gas is cut valve 1 and 8 soon and is opened, and right side burner 5 reclaims the combustion gas sensible heats and left side burner 2 is organized the flash combustion gasification.
When utility model was used for the fuel combustion processing, combustion gas was cut valve 8 and 9 soon and is closed, and inner body wall can be arranged heating surface.When utility model was used for the fuel gasification processing, valve 1,4,8 and 9 periodically opening and closing were cut in combustion gas soon.
Physical changes such as evaporation destructive distillation take place in fuel when falling, resistance slag plate 6 central area temperature height are the efficient burning gasification zone, and air and fuel contact and fast reaction takes place in this zone.High temperature air is crossed a V font stroke at the chamber body back warp, has prolonged the time of staying of oxidant in the combustion gasification district, has strengthened the combustion gasification reaction, makes reaction more complete.Resistance slag plate 6 can rest on the solid matter of imperfect combustion gasification in the efficient burning gasification zone, has prolonged the solid fuel ignition gasification reaction time effectively.
Bulky fume afterheat convection current retracting device is replaced by heat storage, and plant bulk and floor space are dwindled, and be simple to operate.Air themperature reaches 1000 ℃ of temperature levels, and combustion gasification temperature integral level improves, and the reaction of flash combustion gasification takes place, and combustion gasification efficient and thermal efficiency height are stable, and the macromolecular compound complete decomposition of peculiar smell is arranged, and environment for use is clean.Solid matter in the combustion gasification product discharges out of the furnace with the melt cinder form, can be used for building materials or fertilizer granulation after cooling is condensed.Dioxin and tar reaction of formation are inhibited.Can use low calorie fuels.The environmental pollution of all kinds of minimizing low calorie fuels, tap a new source of energy and the utility model all can be used in the place of energy-saving and emission-reduction.
