In actual production process, need repairing if waste heat boiler 6 is out of joint, by intelligent controller 7, transmit an order to the water vapour pump in public steam-pipe so, water vapor pump, to steam jet device 3, for activation furnace 1, is not delayed to production work.
Below the method for Slapple activating furnace 1 cascaded utilization of energy energy saver:
Step one-level: the useless furnace gas main component of Slapple activating furnace 1 that in the past directly entered atmosphere by chimney 8 is water vapor approximately 40%, carbonic acid gas approximately 20%, carbon monoxide, hydrogen and methane class aromatic hydrocarbons approximately 40%, now a part for above-mentioned Slapple activating furnace 1 useless furnace gas is adopted to steam jet device 3, rely on when commutation to pass into self pressure of regenerator 2 bottom water steam, send together the useless furnace gas of 25%-35% back to regenerator 2 bottoms in company with water vapor, reenter the reaction that participates in carbon and water vapor in stove alive, reach and reduce steam consumption and optimize activation phenomenon in stove, improve the object of gac quality.The amount that useless furnace gas enters is to regulate by the pressure of waste heat boiler 6 internal water steams, large the just more of furnace gas inlet of giving up of the pressure of water vapour, and the less amount that useless furnace gas enters of water vapour pressure is just less; The pressure of water vapour will be controlled within the scope of 0.4-0.6 Mpa, pressure is too little, return to the useless furnace gas of regenerator 2 very little, there is no the water vapour in the useless furnace gas of abundant recycle, pressure is too high to be brought too much useless furnace gas into and returns to regenerator 2 and cause total system unstable, the quality to gac and the safety of whole system be have dysgenic.
Step secondary: the useless composition of fumes that the useless furnace gas of Slapple activating furnace 1 does not return to the approximately 75%-65% of regenerator 2 is water vapor approximately 30%, carbonic acid gas approximately 25%, carbon monoxide, hydrogen and methane class aromatic hydrocarbons approximately 45%, 360 DEG C of furnace gas temperatures, these useless furnace gases contain suitable heat, if not accumulation of heat air distribution, direct heat exchange efficiency is very low, so this part useless furnace gas is passed in heat-accumulation combustion chamber 5, first accumulation of heat reaches burning-point, rear air distribution fully burns it, the heat producing is through waste heat boiler 6 heat exchange, the water vapor that waste heat boiler 6 produces, judge vapor pressure sensor by intelligent controller 7, the signal that steam flow sensor transmission comes, control water vapour flow distribution control valve, select the production of a certain amount of water vapour supply activation furnace 1, other needs remaining water vapour supply plant area, as steam turbine power generation or heating installation etc., finally reach cascaded utilization of energy, reduce costs, the object that energy-saving and emission-reduction and efficient circulation are utilized.Temperature 850-950 DEG C in the stove of rear heat-accumulation combustion chamber 5, after waste heat boiler 6 heat exchange, the outer furnace gas temperature of arranging, at 220 DEG C, is arranged outward by blower fan, and the composition of efflux gas is water vapour approximately 30%, carbonic acid gas approximately 55%, nitrogen 15%, 220 DEG C of temperature.Last outer row's furnace gas temperature is too high or too low, equipment is had to impact, if outer grate furnace gas excess Temperature, affect the work-ing life of the equipment such as blower fan, high temperature is larger on equipment impact, makes the unstable potential safety hazard that exists of total system, if outer grate furnace temperature is spent low, lower than dew-point temperature, can produce containing sour steam and cause the corrosion to equipment; And the flue-gas temperature of 220 DEG C is moderate, neither can as high-temperature flue gas, cause damage also can as low-temperature flue gas, not produce corrodibility containing sour water vapour to equipment.
The Slapple activating furnace 1 of the utility model application at present, every Slapple activating furnace 1 is equipped with 3 two, steam jet device, completes useless furnace gas step one-level recycle, reduces the 25%-35% of steam usage quantity; The useless furnace gas of Slapple activating furnace 1 is by the guiding of flue and gate shape reversing system 4, enter a set of heat-accumulation combustor that coupling is equipped with below, in heat-accumulation combustion chamber 5, the first accumulation of heat of useless furnace gas reaches burning-point, after air distribution, make it fully burn, heat carries out after heat exchange at waste heat boiler 6, useless furnace gas is outer row again, completes useless furnace gas step secondary utilization.
The utility model has a kind of embodiment that plural Slapple activating furnace 1 flue is aggregated in a heat-accumulation combustion chamber 5, fully burns and waste heat exchange.
One ton of conventional index gac of the utility model Slapple activating furnace every production of 1 exhaust energy cascade utilization energy saver after tested, waste heat boiler 6 can produce 11 tons of overheated steams, substitute that coal firing boiler meets activation furnace 1 completely self with vapour, can reduce products production cost 15%, practical, there is huge economic worth.
