Referring to a kind of gas retort shown in Fig. 1-4, gas retort inside division is the carbonization being in both sides by heat conduction partition wall 13 Room 12 and the combustor being clipped between two carbonization chambers 12；Combustor is divided into several quirks by quirk partition wall 4, in combustor bottom Separated by first baffle 6 and the first cavity 10 being connected with each quirk 5 is set；First baffle 6 is provided with and several fire The through hole 61 of the corresponding equal sizes in road 5；Air inlet 7 is connected with the first cavity 10.

Heat smoke enters from air inlet 7, in the presence of first baffle 6, produces certain in the first cavity 10 after circling round Pressure, just can be evenly distributed in the first cavity 10 in the short period, enable the high-temperature flue gas of entrance combustor quick Formation steady pressure region；First baffle 6 is provided with the through hole 61 corresponding with each quirk, and in the first cavity 10, distribution is equal Even hot combustion gas enter each quirk of combustor 5 by through hole 61 and are redistributed, and so in each quirk, exhaust gas volumn is essentially identical, And the uniformity of temperature profile on combustor horizontal direction；This intake method saves big quantity space simultaneously, also allows in combustor The regulation of temperature and control.

In the present embodiment, burning interior is provided with 3 road quirk partition wall 4,3 road quirk partition wall and combustor is divided into 4 quirks 5. Because heat conduction partition wall 13 is subject to the lateral shear stress in coal seam in carbonization chamber 12 and bigger apart from the nearlyer shear stress of furnace bottom, so fire Burn the quirk partition wall 4 in room and act the effect supporting heat conduction partition wall 13, strengthen the stability in the large of gas retort.

Specifically, air inlet 7 is the nozzle of horn-like structure, and the wide mouth position of horn-like structure is with the first cavity 10 even Connect, above-mentioned inlet structure makes flue gas in the vertical direction have component velocity vector, thus reducing the lateral velocity of flue gas, more holds Heat smoke is easily made quickly to diffuse to form the region of pressure stability, rapid homogeneity in the first cavity.

More preferably, in order to ensure not having dead angle in each quirk 5, carbonization chamber 12 is heated evenly, corresponding every on first baffle 6 The through hole 61 of individual quirk 5 is provided with 2, and first baffle 6 has altogether 8 through holes 61.

Through hole 61 size on first baffle 6 can be calculated by parameters such as the admission pressure of hot combustion gas and charge flow rates Go out.

In the present embodiment, because gas retort is the bottom coke discharging of furnace roof feed furnace, and furnace bottom limited space, hot combustion gas should not be adopted Spray into burner hearth immediately below furnace bottom, therefore adopt the horizontal intake method of the first cavity from gas retort combustor, specifically, entering , located at the one side of the first cavity, not only structure is simple for above-mentioned intake method, and is easy to control for QI KOU 7.

Improve embodiment as a kind of, referring to shown in Fig. 1 and Fig. 5, the top of combustor separated by second baffle 3 and The second cavity 11 being connected with 4 quirks 5 is set, and second baffle 3 is provided with 4 through holes 31 to be passed through for flue gas, each through hole 31 Corresponding 1 quirk, the top of the second cavity 11 is provided with several gas outlets, and the setting of the second cavity 11 makes the flue gas in combustor Pressure span is stable, reduces due to the impact of extraneous flue gas blower fan draft.

More preferably, some gas outlets are connected with going out gas branch pipe 2, are correspondingly arranged to give vent to anger for 4 with 4 quirks of the present embodiment and prop up Pipe 2,4 going out gas branch pipes 2 are connected with smoke evacuation supervisor 1, so ensure that the uniformity that gas fume of combustion chamber is discharged, reduce to burning The impact of flow of flue gas in room, improves stability.

It should be noted that because the heat transfer wall of bottom of combustion chamber is maximum by the lateral shear stress in coal seam in carbonization chamber 12 , the reasonable altitudes of the first cavity 10 should be the 1/7-1/4 of combustor height, if the first cavity 10 excessive height, that is, is more than combustion The 1/4 of burning room height, and there is no the support of quirk partition wall 4, the stability in the large of body of heater can be greatly reduced；If the first cavity 10 Highly too low, that is, it is less than the 1/7 of combustor height, easily causes that in the first cavity 10, local pressure is too high, may lead to burn In each quirk in room, the distribution of flue gas is not uniform.

The work process of the hot combustion gas of above-described embodiment is as follows：Heat smoke enters the first cavity 10 from air inlet 7, through combustion Burn each quirk 5 in room, enter top of combustion chamber the second cavity 11, high-temperature flue gas are gradually incoming by heat during rising In carbonization chamber, flue-gas temperature constantly reduces, and discharges low-temperature flue gas finally by going out gas branch pipe 2, smoke evacuation supervisor 1.

Obviously, above-described embodiment is only intended to clearly illustrate example, and the not restriction to embodiment.Right For those of ordinary skill in the art, can also make on the basis of the above description other multi-forms change or Change.There is no need to be exhaustive to all of embodiment.And the obvious change thus extended out or Change among the protection domain created still in this utility model.
