Specific embodiment:
As shown in Figure 1, chemical catalyst calcining and decompose gas burn all-in-one oven be by preheating section 1, heating decompose section 2,
Calcining at constant temperature activation section 3, cooling down section 4 constitute furnace body and device for transporting objects 5 and by burner 15, gas pipeline 12,
The compositions such as the burner that combustion-supporting air piping 13 and combustion fan 14 are constituted decompose the row's of being provided with decomposition gas at the top of section 2 in heating
The air inlet mouth of pipe of pipeline 7 and row's decomposition gas blower 6, row's decomposition gas blower 6 decomposes feed channel 7 by row and 2 furnace of section is decomposed in heating
Thorax communicates.It is additionally arranged decomposition gas Burning Room 16 below the device for transporting objects of calcining at constant temperature activation section 3, is arranged on Burning Room 16
Decomposition gas branch pipe decomposes feed channel 8 by conveying and is connected with decomposition gas blower 6 outlet mouth of pipe is arranged.In preheating section 1 and heating point
It solves and is provided with Burning Room discharge flue 11 below the material transmitting device of section 2, and be provided with smoke discharging pipe 10 in preheating section 1, it should
Smoke discharging pipe 10 is connected with the smoke exhaust fan 9 for being mounted on furnace roof.
When implementing the utility model, by taking 62m muffle mesh-belt kiln as an example: expanding in the calcining at constant temperature activation section 3 of mesh-belt kiln and increase
If Burning Room 16, it will heat up to decompose by air-introduced machine 6 and be burned in section decomposition gas feeding Burning Room 16, general organic matter incineration temperature
At 500~600 DEG C, salt or other oxides need 800~900 DEG C of burnings, and chemical catalyst calcination temperature generally exists
500~700 DEG C.Therefore it is distinguished in the design process according to different product different decomposition object, when incineration temperature is higher than calcining temperature
The thickness and material of flame isolation layer are considered when spending;When burning required temperature and being lower than calcination temperature, directly improving incineration temperature makes point
Burning of venting one's spleen is faster more abundant.Flue gas after burning can be discharged out of the furnace by bottom flue gas passage in burner preheating section, flue gas
To material bed carry out radiant heating in bottom flue gas passage 11.
Its process is:
(1) calcining and activating furnace is heated up to decompose product in section 2 and heat up 200~250 DEG C of decomposed tail gas and contain organic compounds pumping
It is sent out to burning in Burning Room 16;
(2) decomposition gas organic exhaust gas burns the heat supply calcining at constant temperature activation section 3 generated and uses, and calcining required temperature is
600 DEG C or so;Improve incineration temperature when heat is inadequate, when heat superelevation adds muffle heat preservation, makes to calcine section moderate temperature;
(3) honeycomb ceramic heat accumulator is added in Burning Room 16, is burning the indoor residence time to improve incineration flue gas,
It is burned to achieve the effect that improve decomposition gas;
(4) 200 DEG C or so low-temperature flue gas are discharged out of the furnace from low-temperature prewarming section 1 by smoke exhaust fan 9.
Catalyst decomposition product Correlative data analysis is provided by owner, decomposition product warp >=850 DEG C can reach after high temperature incineration
National environmental standard, design catalyst decompose feeding burner hearth after gas is extracted out by blower and make burning disposal.It is decomposed in view of burning
The temperature of gas is higher than production temperature, special to have been moved off material furnace zone with the kiln and make exhaust gas incineration area, i.e. kiln 49m
It is set as decomposing gas incineration section to 53m, because material calcining area (traditional kiln is cooling section herein) has been left in this region,
Influence of the temperature to material can accomplish the firing and cooling that do not influence material by scientific selection and reasonable masonry construction.
The decomposition gas burn down mode is better than free-standing flue gas incineration furnace, because of the decomposition gas incineration section and production burner hearth
It is not only to have connected together but also relatively independent organism, the high-temperature gas generated when burning and decomposing gas is to walk roaster hearth warp
Smoke exhaust fan discharge, therefore its utilization rate of waste heat is greatly improved (utilization rate up to 85%~95%), and free-standing flue gas burns
The waste heat of furnace is often directly emptied, and heat utilization efficiency and environment protecting are also unsatisfactory.
The kiln 49m to 53m is used as by the decomposition gas incineration section decomposes gas incineration area, will with two high-power burners
The temperature of area jian be raised to >=850 DEG C for burn decompose gas, for make decompose gas be heated more evenly in the area, jian uses bee
Nest ceramics have made 7 flue gas residence walls, and decomposition gas is made to be appropriately extended by the time of high temperature incineration and burn more equal
It is even.
Incineration temperature due to decomposing gas is higher than production temperature and is herein cooling section by original design, in order to
The cooling of material is not influenced, the design selects the covering thermal insulation layer of quality refractory thermal insulation board work decomposition gas incineration section in this section,
And cooling air hose is added in kiln tail, make material reaches original design temperature from kiln temperature degree.
2000~8000m3/h of waste gas decomposition is generated when calcined catalyst on an hourly basis as reference, because of the larger warp of its air quantity
Be afraid of effectively be digested by burner hearth and influence firing temperature when crossing burner hearth, therefore be provided with what past burner hearth leaked out at kiln 49m
Control valve, and the resisting blower of the extra air quantity of extraction, when production, are comprehensively utilized the two to balance furnace pressure, are made
Temperature in burner hearth is controllably run (note: resisting blower herein is opened and do not opened and determined by furnace pressure) by production curve.
In order to show the pressure working condition for decomposing gas incineration section in real time, a U-shaped pressure is installed at the 49m of kiln
Count the pressure working condition to show this section.
