The dual-purpose straw fuel gas gasification installation of air suction type up and down
One, technical field: the utility model relates to straw fuel gas equipment for gasification technical field, particularly a kind of dual-purpose straw fuel gas gasification installation of air suction type up and down.
Two, background technology: stalk is worked as fuel, has accompanied the rural people to live so far.Bavin standing grain buttress is being piled in China rural area, every household, smoke is curling up from the kitchen chimneys in every family already nothing to be surprised at, turn a blind eye to.Along with development of countryside, the straw fuel gas gasification technology is quietly come into the peasant family.Existing straw fuel gas gasification furnace, the gas production height of last air suction type, it is few to contain tar, but tight to demanded fuel, has only the mixture of corncob or corncob, rice husk, wood chip just to be fit to taste.The materials of following air suction type are wide, corncob, corn stalk, straw, rice husk, sorghum straw, wheat straw, wood chip, leaf, sawdust all can, but gas production is lower, it is many to contain tar.Therefore, when the biomass fuel of real estate can not be used entirely, the one side that has is idle, and what have must outsourcing, causes the waste of material resources, manpower, transport power and financial resources.Simultaneously, supporting existing deduster and the filter of gasification furnace is very simple again with it, contains a large amount of impurity and tar in the combustion gas, and air delivering pipeline is had harm, also user environment is polluted.
Three, summary of the invention: technical problem to be solved in the utility model is exactly that existing straw fuel gas gasification furnace materials are not extensive, gas production is low, dedusting and combustion gas are filtered not thorough, with after drawbacks such as tar pollution are arranged, a kind of dual-purpose straw fuel gas gasification installation of air suction type up and down is provided, and this device is by the dual-purpose straw fuel gas gasification furnace of air suction type, dual-purpose deduster, Pyatyi water cooling filter, vavuum pump and multistage filtering case constitute up and down.The body of heater of the dual-purpose straw fuel gas gasification furnace of air suction type is provided with lighting door, air register, ash hole, ash hole and the upper and lower outlet of combustion gas automatically up and down, and the body of heater top is provided with bin gate, is provided with fire grate and striker plate in the body of heater.Dual-purpose deduster is made of inside and outside cylindrical shell, which is provided with the upper and lower import of combustion gas and joins respectively with the upper and lower outlet of the combustion gas of gasification furnace, and the centre is provided with blind plate.Also be provided with ashpit and gas outlet on the outer cylinder body.Be provided with the helical form dust block board between inside and outside cylindrical shell.Pyatyi water cooling filter is made of the upper and lower case that connects, and lower linked box is provided with fuel gas inlet and joins with the gas outlet of deduster.Two ends and upper linked box internal upper part are provided with shower nozzle in the lower linked box, also are provided with the drawer type filter core before last channel showerhead, and last upper linked box body top is provided with gas outlet and joins with the vavuum pump suction inlet.The multistage filtering case is made of upper and lower casing, and lower box is provided with fuel gas inlet and joins with vacuum pump outlet.Be respectively equipped with filter core in the upper box, multiple different filtrate is housed in it.Last upper box top is provided with gas outlet and leads to air accumulator and user.Operation principle: when stalk fuel is suitable for the air suction type gasification, fuel added to fill up by bin gate on the gasification furnace shut up the door carefully behind the burner hearth and seal, open the blind plate between the last fuel gas inlet of gas outlet and deduster on the gasification furnace, the blind plate of closing down simultaneously between the combustion gas import and export (is suitable for air suction type gasification down as if stalk fuel, blind plate and last air suction type is counter closes, but last bin gate blow-by).By lighting door fire fuel (following air suction type by material loading doors fire), regulate the air register intake, fuel in burner hearth, gasify the combustion gas that produced by on (or down) gas outlet enter (or down) import in the combustion gas of deduster, drop to the deduster bottom along inner core, combustion gas is risen along spiral between inside and outside barrel again, because the effect of helical form dust block board, the dust in the combustion gas is blocked by the multilayer dust block board to be fallen, and is removed by ashpit.Combustion gas rising top is entered in the lower box of water cooling filter by the gas outlet of deduster, filter and the drawer type filter element filtering through the upper and lower shower nozzle water-cooled that connects in the case again, most of impurity and tar are filtered down, enter the multistage filtering case by gas outlet through vavuum pump then.Combustion gas is filtered repeatedly through multiple different filtrates in the multistage filtering case, and pure combustion gas enters air accumulator by gas outlet, enters the user by supply air line at last and is employed.Because it is wide to take above-mentioned technical solution, the beneficial effects of the utility model to be to be suitable for fuel, can be according to biomass fuel resources such as local stalks, choose or air suction type gasification down, need not leave unused or the outsourcing part of fuel, laborsaving province fortune province fund reduces the combustion gas cost; This device is owing to take advanced dedusting, the filtration of Pyatyi water cooling and multistage multiple filtrate to filter repeatedly, and the combustion gas impurity and the tar content that are produced are few, and the gas pipeline life-span prolongs, and user's indoor environment is obviously improved.
Four, description of drawings: Fig. 1 is a structural representation of the present utility model.Fig. 2 is the left view of Pyatyi water cooling filter among Fig. 1.
Five, the specific embodiment:, elaborate a preferred embodiment of the present utility model below in conjunction with accompanying drawing.Referring to Fig. 1 as can be known, the utility model is by the dual-purpose straw fuel gas gasification furnace of air suction type, dual-purpose deduster, Pyatyi water cooling filter, vavuum pump and multistage filtering case are constituted up and down, the body of heater 1 of gasification furnace is provided with lighting door 2, air register 4, ash hole 5, ash hole 6 and the upper and lower outlet of combustion gas (8,7) automatically, body of heater 1 top is provided with bin gate 10, is provided with fire grate 3 and striker plate 9 in the body of heater 1.Deduster is made of inside and outside cylindrical shell (14,13), which is provided with the upper and lower import of combustion gas (17,11) and joins respectively with the upper and lower outlet of the combustion gas of gasification furnace (8,7), and the centre is provided with blind plate.Also be provided with ashpit 12 and gas outlet 16 on the outer cylinder body 13.Inside and outside cylindrical shell is provided with helical form dust block board 15 between (14,13).Referring to Fig. 1, Fig. 2 as can be known, the water cooling filter is made of the upper and lower case (21,19) that connects, and lower linked box 19 is provided with fuel gas inlet 18 and joins with the gas outlet 16 of deduster.Two ends and upper linked box 21 internal upper parts are provided with shower nozzle 23 in the lower linked box 19, also are provided with drawer type filter core 20 before last channel showerhead 23, and last upper linked box 21 body tops are provided with gas outlet 22 and join with vavuum pump 24 suction inlets.The multistage filtering case is made of upper and lower casing (27,25), and lower box 25 is provided with fuel gas inlet 26 and joins with vavuum pump 24 outlets.Be respectively equipped with filter core 29 in the upper box 27, multiple different filtrate is housed in it.Last upper box 27 tops are provided with gas outlet 28 and lead to air accumulator and user.
