Description
The utility model relates to a kind of movable water-cooling reciprocation stove grate that is used for coal-burning boiler and stove.
At present, existing reciprocal grate cooling technology is outside ventilation cooling or fixed water cooling.Outside ventilation Cooling Heat Transfer efficient is very low, does not reach the cooling purpose, so often cause reciprocating furance row significantly by high-temperature oxydation and the accident of dissolving, has seriously influenced the normal operation of boiler or kiln.Fixed water cooling is to have the fixed water-cooled grate plate in angle of inclination one section of the primary zone of fire grate area arrangements, thereby has lost the burning feature that the reciprocal grate automatic movable pokes fire, and has reduced the thermic load of reciprocal grate.For example China Patent No. is 85205269 combined type water-cooling reciprocation stove grate device.
The purpose of this utility model is to avoid above-mentioned weak point of the prior art and a kind of scaling loss, good cooling results of being difficult for is provided, and the life-span is long, and is reliable, make simple, the movable water-cooling reciprocation stove grate that is used for coal-burning boiler and stove that cost is low.
The utility model is achieved through the following technical solutions: easy high-temperature oxydation is a fire grate segment with the main part that dissolves in the reciprocal grate, and the damaged location of fire grate segment is at head, employing is carried out recirculated water cooling mode to the fire grate head, reduce the operating temperature of fire grate segment, can prevent effectively that fire grate segment is by high-temperature oxydation and the generation of dissolving phenomenon, owing to be to carry out effectively cooling at fire grate segment localized hyperthermia position, cause the reduction of its thermal efficiency so can not influence the normal combustion of boiler or kiln simultaneously.Movable water-cooling reciprocation stove grate includes motor 1, decelerator 2, shackle rod 3, coal bunker 4, seamless stove sheet 5, seam stove sheet 6 is arranged, walking beam 7, built-in beam 8, furnace grate support 9 and side seal plate 10, set up water inlet pipe 11 simultaneously, flexible steel in flat section tubing 12, water cooled furnace plate 13, cooling tube 14, return pipe 15 and control valve 16 are formed, cooling tube 14 is arranged on seamless stove sheet 5 and the head of seam stove sheet 6 is arranged, and by cooling tube 14 the fire grate on single laterally polyphone get up, cooling tube 14 on the different rows is connected in turn by flexible steel in flat section tubing 12, two that water cooled furnace plate 13 is arranged on horizontal fire grate is connected with return pipe 15 with water inlet pipe 11 respectively, in order to control the flow size of cooling water in the cooling recirculation system, water inlet pipe is provided with control valve 16.Cooling tube 14 can all or part ofly selectively be arranged on the most flimsy head in the fire grate segment of reciprocal grate.Concrete cooling procedure is: the cooling water of being supplied with by coolant circulation pump enters water cooled furnace plate 13 by control valve 16 and water inlet pipe 11, enter cooling tube 14 again, the high-temperature region of each fire grate segment on the cooling tube polyphone reciprocal grate, under the effect of cooling water, cause the operating temperature of fire grate segment high-temperature region to reduce, thereby prevented fire grate segment high-temperature oxydation and dissolve, cooling water enters cooling bay by return pipe after fire grate segment is carried out cooling, has finished a complete cooling work process.
The utility model has the advantages that simple in structure, cost is low, cooling effect is remarkable, reliable, be convenient to Operation and maintenance, do not influence boiler thermal output, the fire grate of various reciprocating-grate boilers and kiln all can use, thoroughly solved reciprocal grate easy high-temperature oxydation of fire grate that exists for a long time and the problem of dissolving, created condition, reduced user's operating cost for the range of application that enlarges reciprocal grate.
Below in conjunction with drawings and Examples movable water-cooling reciprocation stove grate is described in further detail.
Fig. 1 is the front view of movable water-cooling reciprocation stove grate;
Fig. 2 is the vertical view of movable water-cooling reciprocation stove grate;
Fig. 3 is the scheme of installation of fire grate segment;
Fig. 4 is the cutaway view of Fig. 3 along the A-A line.
Haul of the present utility model system forms like this: coal gets off to be input on the fire grate from coal bunker 4, seamless stove sheet 5 and have seam stove sheet 6 to take respectively on the built-in beam 8 and walking beam 7 that is placed on aligned identical.Each fire grate segment head is upwards raised certain angle, and takes and be placed on the front-seat fire grate segment, and whole show beam 7 and linked into an integrated entity by the shackle rod 3 that two angle steel are formed is installed on the furnace grate support 9.Motor 1 starts, drive shackle rod 3 by decelerator 2, the fire grate segment that is placed on the whole show beam 7 is taken in driving makes it do vertically to move back and forth along taking the fire grate segment that is placed on the row's built-in beam 8 of back, make coal in the coal bunker 4 constantly be transported to each combustion zone on boiler or the kiln fire grate, the both sides of fire grate segment are equipped with side seal plate 10, for fear of burning out of fire grate segment head, make a call to a hole in the centre of each fire grate segment head, by cooling tube they laterally are together in series, cooling tube 14 on the different rows is connected in turn by flexible steel in flat section tubing 12, two that water cooled furnace plate 13 is arranged on horizontal fire grate is connected with return pipe 15 with water inlet pipe 11 respectively, in order to control the flow size of cooling water in the cooling recirculation system, on water inlet pipe, be provided with control valve 16.The cooling water that coolant circulation pump is supplied with enters water cooled furnace plate 13 by water inlet pipe 11, enter cooling tube 14 again, after like this cooling being carried out in this grate furnace screening, cooling water enters in the cooling tube 14 in next grate furnace screening by flexible steel in flat section tubing 12, cooling successively, cooling water enters cooling bay by return pipe 15 at last and cools off, and so just finishes whole cooling work processes.
