Description

New and effective reciprocal promotion grate cooler

Technical field the utility model relates to the new and effective reciprocal promotion grate cooler of a kind of cement mill firing system.

The background technology grate cooler is a kind of grog cooling apparatus the most frequently used in the present new type dry kiln cement producing line, and it has multiple actions such as cooling, recovery of heat, conveying, fragmentation.Modern grate cooler requires to have high cooling efficiency, high heat recovery rate, high characteristics such as operation factor, and the efficient of this equipment is saved energy and reduce the cost to the cement mill very important effect.Because grate cooler is a kind of complex structure, require the more Thermal Equipment of function.Up to the present, also not have both at home and abroad really can to describe the analytic solution or the numerical solution of the multiparameter mathematical model of the alternate mechanical movement of the inner gas-solid of grate cooler two and heat passage (radiation, convection current, conduction) two process mechanisms, this has caused certain difficulty with regard to the design optimization that solves grate cooler to people theoretically.In this case, have only, constantly sum up and grope, approach the target of optimization in practice gradually by practice repeatedly.A large amount of facts have proved, at present existing in the grate cooler of each cement mill operation, the main outstanding problem that exists has: (1). one of them main function of grate cooler be by supply with cooling air fully the cooling down high-temperature grog make its drop temperature that reaches regulation (envrionment temperature+65 ℃), so the rational Design on Plane of air feed system is given full play to it to grate cooler and high-effect very important effect is arranged.Particularly the quality of elevated temperature heat recovery zone air feed system is directly connected to the heat recovery rate of grate cooler.Present grate cooler, the air feed system of elevated temperature heat recovery zone ladder resistance force grid is by a certain given wind speed and supplies with cooling air to grate plate.Seem too high again this given wind speed " for the wind speed that helps the gas-solid heat exchange (requiring lower) ", and seem too low " the sufficiently high wind speed of needs " for helping bed of material uniform distribution.Because the wind speed of the cooling air of supplying with in the elevated temperature heat recovery zone is high more, the residence time of cooling air in the high temperature chamotte layer is just short more, be unfavorable for the gas-solid heat exchange, be unfavorable for improving secondary air temperature and the tertiary air temperature of going into the preheater decomposing furnace, be unfavorable for improving the heat recovery rate of grate cooler into kiln.Be because rotary kiln is the tilting rotator on the other hand, cause its discharging particulate eduction, make grog fall into behind the grate cooler skewness on comb bedside degree and length direction, and the bed of material pockety easily forms " Red River " phenomenon, easily cause the cooling air short circuit, be unfavorable for the gas-solid heat exchange of next process of cooling machine, be unfavorable for improving the cooling efficiency of grate cooler, therefore require to supply with sufficiently high wind speed again at the grate cooler feed end.Obviously, can't satisfy above two conditions simultaneously by a certain given wind speed.(2). grate plate directly is connected by bolt with comb board roof beam, makes joint bolt be subjected to shearing force when the grate plate pusher, the phenomenon that so frequent generation joint bolt is cut off, the Serious Accident that causes grate plate to come off has seriously influenced the operation factor of grate cooler.In addition, this mode of connection makes that the spacing of hot grog of comb board roof beam and grate plate upper surface is nearer, comb board roof beam is vulnerable to the thermal radiation of hot grog, cause the deflection of beam distortion, thereby vertical gap and lateral clearance between grate plate have been strengthened, leakage material between grate plate is increased, aggravated the wearing and tearing of grate plate, net result is the working life that has reduced grate plate widely.(3). because design has leakage material machine for zipper under the air compartment, make that the height of grate cooler is higher, thereby increased in the kiln hood, kiln of firing system, the civil engineering costs of kiln tail.In addition, many operational outfits will increase the failure rate of complete machine, have promptly reduced the operation factor of grate cooler.Also corresponding raising of cost that also has equipment.(4). former rows adopt the grate cooler of ladder resistance force grid, because the opening of the seam of combing is towards the top, the fine particle grog easily falls in the inflation beam of ladder resistance force grid, cause the obstruction in air channel and can't remove, and have a strong impact on the operation factor of grate cooler.And it is extremely inhomogeneous to stitch the air-flow that upwards blows to grog by combing, easily cause the fountain shape of fine particle grog to fly upward, increase the dust circulation between grate cooler and rotary kiln, the red heat grog also can not get sufficient quenching, has influenced the cooling efficiency and the heat recovery rate of grate cooler.

The technology contents the technical solution of the utility model is: (1). at the air feed problem of elevated temperature heat recovery zone ladder resistance force grid, design provides a kind of controlled stream pulse air feed system, the wind speed that makes the cooling air that grate cooler elevated temperature heat recovery zone ladder resistance force grid supplies with by a certain frequency from low to high, back and forth change from high to low again, so both guaranteed " requiring ", guaranteed " needing sufficiently high wind speed for bed of material uniform distribution " again for the low wind speed that helps the gas-solid heat exchange.(2). at the grate plate fixation problem, design provides a kind of novel high strong band of comb board, has increased the distance between grate plate and the comb board roof beam, has reduced the thermal radiation of red heat grog to comb board roof beam thereby reach, and has reduced the purpose of the bending deformation quantity of comb board roof beam; And on the comb board roof beam that grate plate is installed, stopper slot is set simultaneously, make the bolt that connects grate plate and comb board roof beam avoid shearing force.(3). at leaking the material transportation problem, under novel grate plate condition, design provides a kind of method of leaking the material machine for zipper of cancelling, supportingly on novel cooling machine designed novel electronic arc air valve, can directly fall into transfer roller by this device grog, so just reduce the height of whole set equipment, thereby saved the construction investment expense of firing system.In addition, lack the failure rate that an operational outfit will reduce complete machine, promptly improved the operation factor of grate cooler.(4). adopt ladder resistance force grid air channel to stop up the uneven problem of gentle distributions at former rows, design provides a kind of ladder resistance force grid that blows the seam of combing with horizontal, can prevent effectively that the fine particle grog from filling the air falls in the inflation beam and causes the air channel to stop up, make the air-flow that blows to the grog layer by the seam of combing distribute more even, more help quenching and gas-solid heat exchange, the fountain shape of having eliminated the fine particle grog flies upward, and has significantly reduced the dust circulation between grate cooler and rotary kiln.

Because what controlled stream pulse air feed system was supplied with prolongs the residence time of air-flow in the elevated temperature heat grog than low speed cooling wind energy, help grate cooler elevated temperature heat recovery zone and carry out sufficient gas-solid heat exchange, can reclaim more heat in the elevated temperature heat grog with less cooling air, thereby improved two effectively, the tertiary air temperature, improve the heat recovery rate of grate cooler, and reduced the consumption (promptly reduce energy consumption) of cooling air; The sufficiently high cooling wind energy of wind speed that controlled stream pulse air feed system is supplied with makes elevated temperature heat grog timely uniform coming on the bed of combing of unloading from rotary kiln, and obtain express quenching, help eliminating " Red River " phenomenon, and uniform hot grog is beneficial to the gas-solid heat exchange of the follow-up bed of combing.High strong band of comb board has increased the distance between grate plate and the comb board roof beam, reduced of the thermal radiation of red heat grog thereby reach to comb board roof beam, reduced the bending deformation quantity of comb board roof beam, vertical gap and lateral clearance that grate plate is asked have been guaranteed, thereby reduced the wearing and tearing of grate plate, prolonged the working life of grate plate; On the comb board roof beam that grate plate is installed, stopper slot is set simultaneously, makes the bolt that connects grate plate and comb board roof beam avoid shearing force, avoided bolt to be cut off the major accident that causes grate plate to come off, help improving the operation factor of grate cooler.After the material machine for zipper is leaked in the grate cooler cancellation, supportingly on novel cooling machine designed novel electronic arc air valve, grog during the ash awl struggles against down by this device can directly fall into transfer roller, so just reduced the height of whole set equipment, thereby saved the construction investment expense of firing system, lack the failure rate that an operational outfit will reduce complete machine, helped improving the operation factor of grate cooler.The ladder resistance force grid that the band horizontal is blown the seam of combing can prevent effectively that the fine particle grog from filling the air and fall in the inflation beam and cause the air channel to stop up, make the air-flow that blows to the grog layer by the seam of combing distribute more even, more help quenching and gas-solid heat exchange, the fountain shape of having eliminated the fine particle grog flies upward, and has significantly reduced the dust circulation between grate cooler and rotary kiln.
