Description
Technical field
The present invention relates to a kind of roasting system and method thereof, especially a kind of energy-conservation carbon anode roasting system and method thereof.
Background technology
At present, domestic anode-baking is undertaken by ring-form calcining furnace and a supporting 1-3 heating system, and in general, 1 jacket heating system is joined by 12-18 firing chamber; The medium-sized ring-form calcining furnace that only has 16-20 firing chamber to form is produced with a heating system usually.
Fig. 1 is the open-type ring-type roasting furnace operation schematic diagram that Room 38 form, and roasting is divided into two flame systems, and each flame system has 19 furnace chambers, and wherein 6 furnace chambers add thermal bake-out, and 9 furnace chambers are cooling, and all the other 4 furnace chambers carry out shove charge, come out of the stove or repair stove.There is at regular intervals 1 furnace chamber that installs green compact to be concatenated in heating system, have simultaneously 1 furnace chamber of having completed heating to leave heating system and enter the state of cooling, 2 of front and back furnace chamber enters the interval time of heating system by being divided by and getting by the heated oven chamber in 1 system total heat time heating time of the heating curve that adopts.
A flame system is comprised of three burning racks 1 and three thermocouples 5, a smoke discharge frame 6, a thermometric rack of measuring pressure 7, a zero-pressure frame 4, an air blast frame 9 and a cooling frame 8, and system configuration as shown in Figure 2.Ring-form calcining furnace uses coal gas, natural gas or heavy oil to be heating fuel.In system's normal course of operation, only need in a heating system to spray into fuel combustion to three firing chambers of hot stage, several firing chambers of back utilize the volatile combustion heating of overflowing in high-temperature flue gas that the high temperature furnace chamber discharges and green compact, and last 1 preheating furnace chamber is connected waste gas flue combustion gas.The waste gas flue is connected with induced-draft fan, produces draft by induced-draft fan and makes last heated oven chamber keep certain negative pressure, and top high temperature furnace chamber also should keep micro-negative pressure, and therefore, in production process, whole heated oven chamber all are in negative pressure state.The automatic control that fuel is supplied with is adjusted according to each quirk, each temperature conditions constantly, simultaneously, volatile matter is also an important fuel source, controls volatile matter in a large amount of burnings in anode preheating section middle part, and is also of crucial importance to utilizing heat energy and controlling the roasting curve.Utilize properly, the part that volatile matter acts as a fuel can account for more than 35% of fuel consumption in whole production process.
The another key that makes burning be controlled at optimum state is providing of air quantity-oxygen.Air quantity is little, and the oxygen amount is few, and fuel can not fully burn, and under negative pressure state, can be drawn in tobacco pipe waste fuel and volatile matter; And combustible component more than needed in flue gas, at the stove rear portion, explosion danger is arranged, in case the flue gas that has infiltration air and high temperature to contain coal gas meets, the thing of blasting, of common occurrence, this situation explanation, volatile matter and coal gas fail fully to burn in the part-heated oven chamber that should burn and anode preheating furnace chamber, and its reason is mainly anoxic.
In actual production process, the required air quantity of combustion system mainly comes from two aspects.the one, enter from the air blast frame, at first this part air quantity absorbs the anode block that enters the state of cooling and fills burnt heat, after fully improving temperature, for combustion system provides fuel combustion requisite oxygen amount, to guarantee front minute-pressure or the zero-pressure state of high temperature (1# burning rack) heated oven chamber due to combustion system, so this part air quantity can only provide enough oxygen amounts for the burning of high temperature (1# burning rack) heated oven chamber, and inferior high-temperature heating furnace chamber (2#, the 3# burning rack) the required oxygen amount significant proportion of fuel combustion and volatile combustion just from another aspect, system air leakage.System air leakage comprises two aspects: quirk leaks out and the hopper wall leaks out, and just needs to rely on the filling air that leaks out when deficiency in draught that air blast blasts, so that fuel and volatile matter fully burn.How much being directly proportional to the size of negative pressure of system air leakage amount, because the volatile matter of carbon anode enters quirk by hopper wall gap, the negative pressure that keeping system is certain, be conducive to the pre-thermogenetic volatile matter of green anode and enter the quirk burning from hopper along the wall gap, the negative pressure deficiency will affect the suction of volatile matter.But negative pressure is excessive, the cold air that sucks outside system is too much, namely inleakage is excessive, can cause that again flue-gas temperature reduces, affect on the contrary the burning of volatile matter, also strengthen exhaust smoke level simultaneously, easily will be taken away by flue gas without the volatile matter of burning, increase the thermal loss of system, increased anode ton consumption, affected on the contrary system temperature and pressure balance.
