Description
Technical field
The utility model relates to a kind of grate device that back and forth pushes away.
Background technology
The direct combustion technology of rice husk, difference according to boiler combustion mode can be divided into fluidized-bed combustion boiler and grate firing boiler, but the problem that rice husk burns and exists easy firing, after-flame section lime-ash easily to carry coke secretly in fluidized-bed combustion boiler, chain-grate boiler, conventional reciprocating-grate boiler.
CFBC is a kind of combustion process of physics with chemistry of complexity, use general about about 850 ℃ of the interior temperature of fluidized-bed combustion boiler combusting rice hull stove, belong to the low-temperature burning level, though efficiency of combustion height, NOx discharge capacity are low, combustion heat intensity height, load adjustment ability are good, the after-flame degree is poor, the unburned combustible in fly ash height but exist, the easy coking of material returning device, flying dust amount are big, shortcomings such as heating surface wear is serious, equipment power consumption height, maintenance cost height; The characteristics of grate furnace burning are that fire grate burning and space combustion exist simultaneously, and burning has periodically; The chain furnace single face is ignited, and rice husk burns from top to bottom, and after-flame section lime-ash is easily carried coke secretly; Back and forth push away grate and realized the relative motion of rice hull fuel, during combusting rice hull, the NOx discharge capacity is low, combustion heat intensity is big, but the after-flame degree is poor.
The utility model content
The purpose of this utility model provides the big ladder of a kind of special combustion rice husk and back and forth pushes away the grate device, and rice husk after-flame degree is poor, after-flame section lime-ash is easily carried coke secretly to solve, equipment power consumption height, the combustion apparatus life-span is short and maintenance cost is high problem.
The utility model is to solve the problems of the technologies described above the technical scheme of taking to be: described fire grate device comprises the fire grate transmission mechanism; Described fire grate device also comprises a plurality of big notch cuttype fire grates, described each big notch cuttype fire grate is by the fixed grate framework, big ladder movable furnace grate plate, big ladder fixed grate film, the fixed grate crossbeam, moving grate crossbeam and roller constitute, the front end of described big ladder movable furnace grate plate is connected with big ladder fixed grate film, the afterbody of described big ladder movable furnace grate plate is contained on the moving grate crossbeam, the two ends of described moving grate crossbeam are connected with roller respectively, the afterbody of described big ladder fixed grate film is contained on the fixed grate crossbeam, described fixed grate crossbeam is contained in the upper end of fixed grate framework, adjacent two big notch cuttype fire grates connect by the moving grate crossbeam, and described fire grate transmission mechanism is connected with the lower end of moving grate crossbeam.
The utlity model has following beneficial effect: 1. the utility model possesses good top ignition condition, because the fire grate segment ladder is higher, and fire grate segment body and head have air supply hole, make the fire grate segment head cool off, be difficult for scaling loss, the combustion apparatus life-span is long, reduced the cost of maintenance, improved the ability of poking fire, big notch cuttype fire grate segment makes rice husk catch fire and has " bottom catches fire " factor that ignition condition is better in the process of relative motion, the after-flame that helps rice husk, after-flame section lime-ash is not with coke.2. the utility model combusting rice hull makes full use of agricultural wastes, reduces environmental pollution, reaches energy-saving and emission-reduction, improves the purpose of comprehensive benefit.
