Abstract
The utility model provides a stalk gasified gas device which is composed of a gasification stove, a dust remover, a cooling tower, a washing tower, a filter, a blower fan, a water sealing device and a gas storage tank, wherein the gasification stove is composed of an inner chamber and an outer wall; both sides of the upper end of the outer wall of the gasification stove are provided with gas outlets, the inner side face is provided with a fire resistant heat-insulating layer, and a high-temperature zone is formed between the heat-insulating layer and the inner chamber to further promote tar oil in gas to crack and be carbonized. A water inlet pipe, a spraying baffle plate, a gas choking baffle plate and a bottom drain valve are additionally installed between a gas inlet and a gas outlet of the dust remover to ensure that tar oil and dust deposited in the dust remover can be cleaned thoroughly so as to further improve the performance of the complete device. In addition, the utility model also has the advantages of convenient operation, high purity of generated gas and power saving.
Description
Technical field
The utility model relates to a kind of biomass pyrogenation gasification technical field, especially a kind of gasifying stalk gas combustion apparatus.
Background technology
Biomass gasification technology is that biomass material burns under anoxic condition and the conversion process of energy of reduction reaction, and it can be converted into the solid biologic raw material inflammable gas easy to use and cleaning.Disclosed at present various stalk gasifiers, its structure mainly are following suction lower-discharging types, that is to say raw material from pyrolysis, oxidation, reduction, and the combustion gas that is produced is directly discharged from the below of stove.This structure cracking process is very short, makes the coke tar cracking carbonization in the combustion gas not thorough, makes in the combustion gas oxygen level higher, and this suction lower-discharging type structure down also causes gas outlet to be stopped up by ash easily; Traditional in addition fly-ash separator has only single dedusting function, and its tar and dust deposit also cause the obstruction of fly-ash separator gas outlet easily in fly-ash separator.
Summary of the invention
The utility model provides a kind of combustion gas purity height, the better gasifying stalk gas combustion apparatus of dust removing effects for solving the technical problem that exists in the known technology.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
A kind of gasifying stalk gas combustion apparatus, by gasification burner, fly-ash separator, cooling tower, washing tower, strainer, gas blower, water seal arrangement, and gas holder is formed, gasification burner is made of interior thorax and outer wall, there are opening for feed and porthole in the upper end of interior thorax, the lower end of interior thorax is a fire grate, several inlet mouths are arranged on the side of interior thorax, interior thorax inside is equipped with the combustion zone inlet pipe that is connected with each inlet mouth, the outer wall of gasification burner is equipped with gas outlet, lower end one side of fly-ash separator has fuel gas inlet, there is gas outlet the upper end of fly-ash separator, and the gas outlet of described gasification burner outer wall is installed in both sides, outer wall upper end, and thermal insulation layer has also been built in gasification burner outer wall inboard; Upper end one side in the described fly-ash separator also is equipped with water inlet pipe, and the below of water inlet pipe is equipped with choke baffle plate and spray baffle plate, and fly-ash separator fuel gas inlet the inner is a horizontal pipe, and downside is shaped on opening.
The utility model can also adopt following technical measures:
The section of thorax is trapezoidal in described.
Advantage and the positively effect that the utlity model has are: owing to double gas port being set on the outer wall of gasification burner, being provided with refractory insulating layer in the outer wall inboard, form a high-temperature zone in making between the thermal insulation layer of thorax and outer wall, the combustion gas that thorax is produced like this can be passed through in interior thorax high-temperature zone on every side equably, help the further cracking carbonization process of tar, also prevented the obstruction of gas outlet; On the basis of traditional fly-ash separator, add spray in addition, make combustion gas and water butt head-on fully, form the aqueous vapor haze, the temperature of combustion gas sharply descends, tarry vapours moment changes into liquid tar, along with the dust that enters in the fly-ash separator is taken away by water, has eliminated obstruction hidden danger greatly.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1 gasification burner; 2 fly-ash separators; 3 cooling towers; 4 washing towers; 5 strainers; 6 gas blowers; 7 water seal arrangements; 8 gas holders; 9 thermal insulation layers; 10 high-temperature zones; 11 gas outlets; 12 opening for feeds; 13 inlet mouths; 14 inlet pipe; 15 fire grates; 16 portholes; 17 spray baffle plates; 18 choke baffle plates; 19 water discharge valves; 20 fuel gas inlet; 21 gas outlets; 22 water inlet pipes.
Embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1, gasification burner 1, fly-ash separator 2, cooling tower 3, washing tower 4, strainer 5, gas blower 6, water seal arrangement 7, gas holder 8 connect successively by pipeline.Gasification burner 1 is made of interior thorax and outer wall, there are opening for feed 12 and porthole 16 in the upper end of interior thorax, there is fire grate 15 lower end of interior thorax, and circumference side, interior thorax top is provided with several inlet mouths 13, the inlet pipe 14 of thorax bottom (oxidation zone) in each inlet mouth the inner all is connected with and leads to.At gasification burner outer wall medial surface block refractory insulating layer 9 is arranged, form a high-temperature zone 10 in making between thorax and the outer wall thermal insulation layer, in both sides, gasification burner outer wall upper end two gas outlets 11 are set also, after combustion gas is come out from interior thorax again through the high-temperature zone, discharge from top gas outlet, not only make the tar in the combustion gas can be in interior thorax bottom (zone of oxidation) cracking carbonization, again can cracking carbonization in the high-temperature zone, and prevented the obstruction of dust to gas outlet.As shown in Figure 1, lower end one side of fly-ash separator is equipped with fuel gas inlet 20, and the fly-ash separator upper end is equipped with gas outlet 21.For dedusting more effective, in the fly-ash separator upper end water inlet pipe 22 that leads to inside is installed, the water inlet pipe below is equipped with choke baffle plate 18 and spray baffle plate 17, make the horizontal pipe of open lower side in fuel gas inlet the inner of fly-ash separator lower end, one side is equipped with water discharge valve 19 in the bottom of fly-ash separator, make the combustion gas of fly-ash separator fuel gas inlet and water butt head-on fully like this, tarry vapours moment is changed into liquid tar, along with the dust that enters fly-ash separator is taken away by water together, prevented that tar and dust from stopping up the gas outlet of fly-ash separator, further improved machine performance.
