Description
Technical field
The present invention relates to a kind of combustion furnace technical field of industrial low calorific value waste gas burning processing, especially a kind of synthesis
Ammonia, methanol, hydrogen peroxide and other fine chemical products are using high in blowing-out gas caused by fixed bed batch-type gas making furnace and emptying
The combustion furnace of calorific value waste gas burning, produce high-temperature flue gas and provide condition for follow-up waste heat recovery.
Background technology
Existing industrial low calorific value waste gas (such as nitrogen fertilizer plant's fixed-bed intermittent formula Gas-making Furnace blowing-out gas) due to combustible component is low,
Temperature is low, recycles that value is not high, and most of producer is directly vented, and environment is polluted and the wasting of resources, due to environmental protection
The newly-built air blown gas recovery unit of pressure some producers, but furnace design is that flat-top is flat, and heat-insulation layer and recuperation layer are not
Rationally, cause high heating value gas consumption high, combustion instability, if high heating value gas supply is insufficient, when furnace temperature is too low, Shi Youfa
Raw explosion accident.
The content of the invention
The present invention is for the problem of industrial low calorific value waste gas burning processing is present at present, there is provided a kind of low-heat of highly effective and safe
It is worth waste gas burning stove.A kind of low calorific value waste gas combustion furnace of highly effective and safe is mainly fired by upper cone, low-heat valve burner, high heating value
Burner, heat-insulation layer, recuperation layer, lower cone are formed.It is characterized in that 1. low-heat valve burner and high heating value burner are provided separately, it is first
First be advantageous to air and the premix of combustion gas, improve efficiency of combustion；Next is easy to adjust, and high heating value combustion is adjusted according to in-furnace temperature
Throughput, avoid consuming a large amount of high heating value combustion gas, be advantageous to save；Temperature in high heating value gas flow control stove is finally adjusted at any time
Degree, it is ensured that low calorific value waste gas is stable to burn, and ensures safety.2. low calorific value waste gas combustion furnace uses the structure of cone bottom and the vertex of a cone, it
Than same diameter, its combustion space of the flat-tope structure combustion furnace of identical cylinder height and residence time increase by more than 20%, it is negative
Lotus is also just corresponding to improve more than 20%.Cone structure combustion furnace, the gravity of furnace roof and furnace roof inner thermal insulating layer is fallen into body of heater to prop up
Hold, then pass to basis, therefore furnace roof and furnace wall are all not easy crack of collapsing or have, it is fool proof reliable；Bottom structure is bored again than flat
The other structures combustion furnace of the same diameter of bottom structure and identical simplified height, there is bigger combustion space, in overall structure,
Low calorific value waste gas combustion furnace gravity is fully fallen on the ring-like beams of concrete on body of heater periphery, bores bottom not by gravity, therefore can be big
The big material for saving furnace bottom and basis and safe and reliable.3. low calorific value waste gas combustion furnace inner thermal insulating layer uses composite construction, and
Reserved dilatation joint measure, avoid producing crack, so as to greatly improve heat insulation effect and security performance, ensure equipment long period safety
Operation, while be the most effective method for improving burning in-furnace temperature and flue gas tapping temperature again.Otherwise, heat spreads out of stove from crack
Outside, radiation loss, also potential safety hazard are increased.4. recuperation layer is made up of arch ring, deflection plate, checker brick, using accumulation of heat brick body
Multistage deflection plate checker brick arrangement mode, it both can guarantee that repeatedly mixing contacted ignition and burning repeatedly for fuel gas and air
To the greatest extent, dust stratification while is eliminated again to block, and reaches the good result of long-term operation.
The structure and operation principle of a kind of low calorific value waste gas combustion furnace of highly effective and safe be：Above and below low calorific value waste gas combustion furnace
Push up as cone-shaped structure, centre is cylinder body of heater, and upper cone, lower cone and furnace interior set heat-insulation layer, heat-insulation layer composite construction
Be to be made up of heat-resisting high-alumina brick, insulating brick, alumina silicate heat-preservation cotton, can reduce thermal loss to greatest extent, recuperation layer by arch ring,
Deflection plate, checker brick are formed, and arch ring supports checker brick and deflection plate above in lower portion of furnace body, and checker brick use light weeight alumina brick
Amount of stored heat is big again and permeability is not easily blocked well for grid-like arrangement, i.e. high temperature resistant, and deflection plate uses High-Alumina baffling brick, it is ensured that
Repeatedly mixing contacts ignition and burning-up to combustible exhaust gas repeatedly with air, and upper of furnace body sets low-heat valve burner and height respectively
Calorific value burner, it is ensured that low calorific value waste gas and high heating value combustion gas are sufficiently mixed with air, reach the purpose of completely burned, lower cone
Bottom is provided with dust inlet, and so as to ash discharge, upper cone top is provided with explosion-proof manhole, prevents so that maintainer enters stove inspection and safety
It is quick-fried.
