Yet, to the coking chamber C1 of pit kiln C loading coal the time and doing, has slipped the back when coking chamber C1 discharges coke, still the dust that have generation to emit from the kilneye of pit kiln C more.
That is to say, when loading coal, under the state of the tegillum on open bell 102 tops, owing to make the height homogenizing of coal in the coking chamber C1, promptly carry out smooth operation, so increase from a side of configuration kickoff mechanism, the dust of promptly emitting from the kilneye C2 of host computer side by the finisher of kickoff mechanism.
On the other hand, when discharging coke, because in a side of configure host side and Guide vehicle, promptly the both sides of coke side, because bell 102 takes off from coking chamber C1, red heat coke in the coking chamber C1 just is the state that exposes to the outside in the total length that kilneye C2 runs through coking chamber C1 above-below direction, thus, a lot of dust can take place in the coke from red heat.And then, by the driving of the pressure head of kickoff mechanism with coke when coking chamber C1 releases, because the red heat coke discharges to coke ca from the kilneye of coke side through Guide vehicle, so the dust of being emitted from the kilneye C2 of coke side is just very many.
When such dust is multiple, in order to make and can to collect dust effectively as the corresponding kilneye cover 103 of the coking chamber C1 of object, the switching adjustment doors 104a of common blocked state is set respectively in each contact pipeline 104, and just the kilneye cover 103 of control of dust object is carried out open operation.Thus, for example when coking chamber C1 discharges coke, the dust of being emitted from this coking chamber C1, open adjustment doors 104a is that the kilneye cover 103 of open state is collected, imports the control of dust treater that is provided with on the ground by aggregation pipe 105, carries out the control of dust processing.
But, in above-mentioned stove mouth dust collection device 100 always, because each kilneye cover 103 is arranged on the top of the kilneye C2 of each coking chamber C1, so under the state that takes off bell 102, quite long from the red heat coke that exposes outside lengthwise to the distance of kilneye cover 103, so, the hot gas flow that comprises the dust that is taken place from the red heat coke is before arriving kilneye cover 103, for example when being subjected to interference effects such as upsweep leg, dust outwards spread in the gas before arriving kilneye cover 103, was difficult to it is collected reliably.So practical situation are that stove mouth dust collection device 100 does not always reach the antipollution effect of ideal.
So, be the scheme of having considered to increase kilneye cover 103, having enlarged the capture range of dust with above-mentioned kilneye dust collection manner always, but do like this that the kilneye cover can be with mechanically moving, be interference such as kickoff mechanism and Guide vehicle, so be actually irrealizable.
Summary of the invention

In addition,, can also list under the state that bell is installed on the coking chamber after coke is discharged, when feed coal is packed this coking chamber into from furnace roof by the car of packing into, make the smooth operation of the height homogenizing of the coal in the coking chamber as the operation of kickoff mechanism inherent.Carrying out these a series of operating periods, though emitted a large amount of dust from the kilneye of pit kiln to the outside, stove mouth dust collection device of the present invention is just in order effectively to be collected in the device of these dust of control of dust.
Like this, 1 described invention according to the present invention, by being provided with the dust gathering arrester of kilneye as object a side of kickoff mechanism and Guide vehicle or both sides (following they are generically and collectively referred to as work mechanism), can move to the state of the coking chamber of the manipulating object of emitting a large amount of dust by opening of bell at work mechanism, make this dust gathering arrester be the state relative, so a large amount of dust of being emitted from coking chamber red heat coke can be collected by dust gathering arrester reliably with the kilneye of coking chamber.
In addition, particularly being provided with a side of kickoff mechanism (main frame one side), when loading coal in coking chamber, carried out smooth operation for the height homogenizing that makes coal in the coking chamber.Though this moment, dust was also discharged to the outside from the open tegillum of bell, by dust gathering arrester is set on kickoff mechanism, can collect the dust of emitting from this tegillum effectively.
Like this, 1 invention according to the present invention, can solve existing in existing fixed formula furnace side cover, for from the kilneye of open bell or the problem that dust that the tegillum mouth under the bell state emitted can not be collected reliably is installed, can prevent reliably that thus dust from from the dispersing of pit kiln, making big contribution to air conservation.
The present invention's 2 described inventions are in the present invention's 1 described invention, it is characterized in that described dust gathering arrester can cover the top and the both sides of operating area in the kilneye.
In this invention, the operating area of so-called kilneye, be meant with comprising and discharge corresponding and operating area that set in the stokehold, a plurality of chambers of coking chamber of a plurality of kilneyes of the kilneye that becomes manipulating object of coke operation from coking chamber, in this operating area, the operator discharges described a series of operations such as coke.
Like this, 2 invention according to the present invention, because dust gathering arrester can cover the top and the both sides of the operating area of kilneye, so at work mechanism under the state that the coking chamber of manipulating object moves, in the operating area, stokehold that comprises this coking chamber, be not only the dust of emitting, and the dust that described a series of operation the time is taken place in the operating area also can be collected by the dust gathering arrester of the top in overwrite job zone and both sides from kilneye.Can will carry out control of dust at almost whole dust that the operating area took place more reliably.
So only be provided with in the particle collector of cover on kilneye top existing, the problem that the sidepiece of the kilneye that meeting generation dust never all covers is emitted to the outside, but 2 invention according in the present invention just can not produce such problem, and the collection effciency of dust is greatly improved.
The present invention's 3 described inventions are in the present invention's 2 described inventions, it is characterized in that, and described dust gathering arrester, and then also have the bottom wrapper plate that covers of bottom of dust in the kilneye being emitted more the zone.
In this invention, so-called dust is emitted the zone more, be meant in described operating area the zone that from kilneye, particularly emits a lot of dust, particularly, be that the kilneye of discharging the coking chamber of object with coke is a benchmark, have identical width, zone above the specified altitude position to being less than this benchmark kilneye.
Like this, 3 invention according to the present invention, can cover the bottom wrapper plate that described dust is emitted the bottom in zone more owing in dust gathering arrester, be provided with, so dust of emitting from kilneye, its major part all is induced into this wrapper plate place, bottom, and be not subjected to the influence of foeign element, can reliably be collected into dust gathering arrester.
So, in the past, emit the zone at dust is not provided with in the fixed dust gathering arrester of pit kiln of bottom wrapper plate more, emit dust in case emit the zone at dust from kilneye more, then owing to there is not the wrapper plate that guides this dust, so the outer air-flow from downside will enter in the dust gathering arrester, thus, have the problem that to collect dust by dust gathering arrester effectively.But 3 invention by the present invention just can not produce such problem.
The present invention's 4 invention, the present invention 1～3 in any described invention, it is characterized in that,, be provided with and be fixed on the pit kiln and can prevent from the dust that the dust that kilneye is emitted disperses to the outside anti-locking apparatus that disperses in the top position of described kilneye.
According to this invention, the gas that contains dust of emitting from open kilneye, at high temperature proportion reduces and becomes lighter than extraneous air, rise in surface from kilneye along pit kiln thus, the gas that contains dust of this rising, owing to dispersing in the dust gathering arrester of anti-collected work mechanism one side that leads of locking apparatus, so can more effectively collect from the dust of kilneye by being fixed on dust on the pit kiln.
In addition, in pit kiln one side dust not being set disperses under the situation of anti-locking apparatus, be necessary the part on top, the overwrite job in the dust gathering arrester of the work mechanism one side zone surface with pit kiln is joined, but surface at pit kiln, clamping kilneye and be provided with the member (concrete is strut) that is used to support body of heater, avoid with this member interferential state under, not only at mobile machine, be to be provided with on the work mechanism that to replace the disperse device of anti-locking apparatus of described dust very difficult, and promptly allow to accomplish, cost is increased substantially.For the raising of operating device cost, it is useful that the dust anti-locking apparatus that disperses is set on pit kiln.
The present invention's 5 invention, be in the present invention's 4 described inventions, it is characterized in that, described dust gathering arrester, have and the disperse upper guard-plate of anti-locking apparatus opposite face of described dust, this upper guard-plate have its leading section can and dust disperse that anti-locking apparatus joins join posture and with remove the releasing of joining and work as and connect the structure that alters one's posture between the posture.
According to this invention, under the state of the kilneye opposite face of the coking chamber of work mechanism and manipulating object, the anti-locking apparatus that the dust of the leading section of upper guard-plate and furnace side dispersed by the state that upper guard-plate is set at the posture of joining joins, thus, because dust gathering arrester is emitted zone with the dust of kilneye more and is the state that covers fully from top by the dust anti-locking apparatus that disperses, so the dust of emitting from kilneye can be reliably collected by dust gathering arrester.
Like this, when work mechanism moves, because by become the state that removes the posture of joining that connects from the posture of joining with upper guard-plate, and make dispersing of this upper guard-plate prevent being removed joining of locking apparatus for dust, so work mechanism can make upper guard-plate not disperse with dust and prevent that locking apparatus takes place to disturb and successfully move.
The stove mouth dust collection device of the present invention's 6 described pit kiln, attract and carry out control of dust and handle collecting from the dust of emitting by the kilneye of each coking chamber that is arranged side by side the pit kiln that a plurality of coking chambers constitute, it is characterized in that: dispose on the work mechanisms such as being located at the kickoff mechanism that when each coking chamber is discharged coke, uses, Guide vehicle and machine that dust and airflow are attracted simultaneously on pipeline, with the connecting tube that is connected with pipeline on this machine, and the fixed precipitron body that is connected with this connecting tube.
According to this invention, on the basis that the dust that kilneye took place of pit kiln is being collected, absorbed by pipeline on the machine with airflow, and import fixed precipitron body by this connecting tube, carry out control of dust at this precipitron body and handle.Like this, because the precipitron body is a stationary device, so compare with the situation that precipitron is set on the machine of work mechanism, can adopt the restriction that is not subjected on the machine, the main equipment with excellent control of dust ability, the dust that the kilneye at pit kiln can be taken place is collected and control of dust more reliably thus.
The present invention's 7 described inventions are in the present invention's 6 invention, it is characterized in that described connecting tube moves even have described work mechanism, with the state of outer hermetic seal under also can keep the structure of the state that is connected with pipeline on the machine continuously.
According to the present invention, even for example among work mechanism moves, owing to can keep the connection state of pipeline and connecting tube on the machine, can not send into problems such as precipitron body so can not occur in the moving of work mechanism collected dust, see from secular viewpoint and can improve comprehensive dust collecting efficiency.
In addition, by always physical construction with machine under pipeline and the situation that connecting tube is connected, syndeton with the corresponding number of number of coking chamber is set on connecting tube, simultaneously, the switching adjustment doors is set in each syndeton, on the other hand, must be on machine pipeline one side attended operation mechanism is set and opens and closes the opening and closing operations mechanism of adjustment doors, this not only makes and is arranged on the cost rising, and only consider from physical construction, the connection portion is sealed fully also very difficult, so gas outside in connecting tube, attracting, the air quantity of Zeng Jiaing thus, thereby the load of precipitron body is increased, can produce the problems such as running cost rising of precipitron body thus, but in the present invention's 7 invention, even since in the moving of work mechanism also can with the state of outer hermetic seal under keep the connection state of pipeline and connecting tube on the machine continuously, so there is no need to be provided with a lot of switching adjustment doors etc., this just can contribute to the cost that reduces equipment, simultaneously, can also avoid because the outer gas that enters from the gap increases air quantity, thereby make the problems such as running cost increase of precipitron body.
And then, 7 invention according to the present invention, by the precipitron body that in the moving of the work mechanism that does not carry out the kilneye control of dust, also remains in operation, make and the air of kilneye operating area can be sucked, often new air is sent into the operating area, so the compulsory replacement by this air, the temperature to the machine of face portion that can control with the work mechanism of pit kiln opposite face raises, and therefore can prevent the aging and damage of the machine that caused by high temperature etc. effectively.

In the present embodiment, above-mentioned sidepiece covering lid 21, size is provided with forr a short time than the size up and down of operation zone Z1 about it, simultaneously, its length dimension (with the perpendicular direction of the stove column direction of pit kiln C), be provided with and the sidewall of strut 101 and kickoff mechanism body 91 between size basic identical, thus, the both sides of the width of the position, stokehold of a plurality of the part of pit kiln C (being operating area Z1) are all covered by a pair of sidepiece covering lid 21.
Said machine casing 22, have than the lower end edge portion of the kilneye cover 103 base plate 22b on the top board 22a that is provided with of lower position, and opposite parallel with this top board 22a slightly in the bottom, cover the backplate 22c of the hinder marginal part of top board 22a and base plate 22b, and the framework 22d that supports them, and between top board 22a and base plate 22b, be formed with the attraction path of pipeline 30 on the dust importing machine that will between them, collect.
In this casing 22, as shown in Figure 5, be the leading section of pipeline 30 on the above-mentioned machine of two strands of shapes, connect by backplate 22c.And, in each top board 22a, be provided with to the pit kiln C that extends at the central part fore-and-aft direction of width and the inclination recess 22e that front end rises in this inclination recess 22e, is equipped with cylinder assembly 25.
Above-mentioned upper guard-plate 23 is that baffle body 23a of " ヘ " type and the support 23b that is provided with from the hinder marginal part of this baffle body 23a oblique upper projection backward constitute by lateral plan.This upper guard-plate 23, its base end side around the back shaft that extends to the horizontal direction parallel with the pit kiln of the front end upper edge that is arranged on described framework 22d row, free to rotate support by axle, simultaneously, on leading section below the leading section of kilneye cover 103 state and of joining for joining for removing this state that joins, front-end edge portion to the releasing form of joining that the front lower place tilts, can between these two, change posture.
In Fig. 5, represented is with the top of high order end and low order end by the join example of setting state posture of the releasing of upper guard-plate 23.Simultaneously, Zhong Yang two upper guard-plate 23 is the posture of the state that joins.
Such upper guard-plate 23, width dimensions is compared with the pitch (strut 101 of adjacent setting is the distance of direction extension medullary ray up and down) of pit kiln C, can be set to short size, also can be set to long size.In example shown in Figure 5, expression be the situation that the width dimensions of upper guard-plate 23 is provided with identically with the pitch of pit kiln C, but the present invention is not limited to this, for example, the width dimensions of upper guard-plate 23 can be provided with to such an extent that be 1.5 times of pitch of pit kiln C etc., can set as the case may be and aptly.
In the present embodiment, above-mentioned under shield 24, width dimensions are set to identical substantially with the pitch of pit kiln C, with the corresponding state of kilneye C2 of each coking chamber C1 under, be fixed in the leading section of the framework 22d that supports above-mentioned base plate 22b.This under shield 24 descends and forms towards the pit kiln front end, as shown in Figure 5, and position, the slightly upper opposite face of leading section and bell 102.Like this, under upper guard-plate 23 is set to join the state of posture, the hot hot gas flow of dust-laden that the kilneye C2 that open from bell 102 are taken place, because with respect to air is heated state, so difference in specific gravity that causes and it is risen obliquely upward, through the kilneye 103 of the anti-locking apparatus that disperses as dust, between under shield 24 and upper guard-plate 23, through casing 22 and importing machine upper conduit 30.
Above-mentioned cylinder assembly 25 being provided with on the top board 22a of casing 22 that depression is provided with and extending and the cylinder barrel 25a that installs, the piston rod 25b that protrudes from the leading section of this cylinder barrel 25a along the fore-and-aft direction of inclination recess 22e.The rearward end of cylinder assembly 25a, can support with axle around the coupling shaft 25d that is connected with the support 25c that is provided with at inclination recess 22ed rear portion with rotating freely, simultaneously, the leading section of piston rod 25b, the coupling shaft 23c that can be connected around the support 23b with projection setting on above-mentioned upper guard-plate 23 supports with axle with rotating freely.
So, by driving piston rod 25b is retreated by cylinder assembly 25, baffle body 23a rotates around back shaft 26 along clockwise direction by support 23b, thus, shown in solid line among Fig. 6, be set front-end edge portion and kilneye cover 103 and be the state of the posture of joining of joining, on the other hand, by retreating of piston rod 25b, baffle body 23a is rotated around back shaft 26 in the counterclockwise direction by support 23b, thus, shown in two 2 lines among Fig. 6, be set to the join state of posture of releasing that the end of front-end edge portion descends.
And, the part of surrounding by thick two dot chain line among Fig. 6, promptly at the lower position of dust gathering arrester 20, work mechanisms such as bell assembling/disassembling machine 94 (Fig. 2) and bell scavenger are installed, promptly set so-called mechanical region M, because being formed with above-mentioned backplate 22c at the rear of this mechanical region M prolongs the wall of setting downwards, so dust can not be emitted to the outside by mechanical region M.
Fig. 7 is for the explanatory view of effect of the present invention is described.(A) being to be set under the state of the posture of joining at upper guard-plate 23, is the situation of upstream from the dust-contained airflow of pit kiln C.(B) being to be set under the state of the posture of joining at upper guard-plate 23, to the situation of slightly emitting in horizontal direction, is to be set above-mentioned two kinds of situations under the state of removing the posture of joining at upper guard-plate 23 from the dust-contained airflow of pit kiln C (C).
At first, under the situation that the dried slide of feed coal in coking chamber C1 finishes, take off bell 102, the coke of red heat will be in the outside state (can play second coking chamber C1 with reference to the right side among the figure 1) that is exposed to, still, and in this state, shown in Fig. 7 (A), rise to the operating area Z1 of kilneye C2 from the dust of coking chamber C1 with hot gas flow S1, the kilneye cover 103 by the anti-locking apparatus that disperses as dust is collected into upper guard-plate 23, is attracted in the machine upper conduit 30.
In contrast to this, when the time continuously to coking chamber C1 loading coal, open tegillum 106 under the state of bell 102 (playing second coking chamber C1 with reference to a left side among the figure 1) is installed on coking chamber C1, in this state, because the finisher 93 (Fig. 2) of kickoff mechanism 90 inserts in the coking chamber C1 and to-and-fro movement from the tegillum mouth, promptly, carry out smooth operation, so, shown in Fig. 7 (B), when finisher 93 retreats, may contain the situation of the coal gas stream of superfine pulverized coal from the ejection of tegillum mouth.This raw coal air-flow S2, though be to eject with the state of keeping straight on obliquely upward from the tegillum mouth, but this raw coal air-flow S2, because it is collected and import in the dust gathering arrester 20 by the baffle plate 24 of bottom, so can prevent from not exist the raw coal air-flow S2 that taken place under the situation of baffle plate 24 and the face side of kickoff mechanism 90 directly to impact, and can prevent the problems such as deterioration of the Working environment that causes thus reliably in the bottom of existing apparatus.
In addition, by under shield 24 is set on dust gathering arrester 20, air is from 20 interior the entering and can be stoped effectively by this under shield 24 of mechanical region M side direction dust gathering arrester, so can avoid owing to air flows into the following degradation problem that dust gathering arrester 20 interior diluting effects make the collection effciency of hot gas flow S1 and raw coal air-flow S2.
Like this, under the situation of mobile kickoff mechanism 90, the under shield 24 of, join posture as in Fig. 7 (C) two dot chain line shown in 103 that join with the kilneye cover is by the driving of cylinder assembly 25 (Fig. 5), shown in solid line among Fig. 7 (C), changing to joins removes the state of posture.Thus, kickoff mechanism 90 can not be subjected to the interference of kilneye cover 103 at upper guard-plate 23, and walking successfully.
In addition, join posture and remove the upper guard-plate 23 that posture changes mutually by being provided with to make, for example hinder for some reason and wait under the situation about stopping at precipitron body 50, owing to remove the state of posture by upper guard-plate 23 being made as join, between upper guard-plate 23 and kilneye cover 103, form the gap, make natural ventilation in the Z1 of operating area, circulate with ambient atmos, produce inappropriate high temperature etc. so can prevent the Working environment in the Z1 of operating area, simultaneously, can also prevent mechanical thermal ageings such as bell assembling/disassembling machine 94 and clearer etc. effectively.
By above detailed description as can be known, the present invention is the dust that the kilneye C2 to each coking chamber C1 of the pit kiln that forms from being arranged side by side a plurality of coking chamber C1 is emitted, collect the stove mouth dust collection device 10 that attracts and carry out the pit kiln of control of dust processing by dust gathering arrester 20, because above-mentioned dust gathering arrester 20 is arranged on part with the above-mentioned kilneye C2 opposite face of employed kickoff mechanism (work mechanism) 90 when each coking chamber C1 discharges coke, so, kickoff mechanism 90 move to emit a large amount of dust manipulating object (for example when feed coal being packed into coking chamber C1, after dried slide disposes when coking chamber C1 discharges coke K) the state of coking chamber C1 under, this dust gathering arrester 20 can be the state on opposite with the kilneye C2 of coking chamber C1, can eliminate by the fixed furnace side cover of existing apparatus and can not can collect a large amount of dust reliably by dust gathering arrester 20 corresponding to problems such as the multiple moment of dust.
Like this, by dust gathering arrester 20 being set at the top of the operating area Z1 that can cover kilneye C2 and the shape of both sides, the kilneye C2 of pit kiln can be covered at the dust gathering arrester 20 with the part setting of kilneye C2 opposite face, so dust of being emitted to kilneye C2 from coking chamber C1, compare with the situation that cover only is set on the top of kilneye C2 of existing apparatus, can not take place never to cover fully and from the side of kilneye C2 outside problem such as effusion, can collect by dust gathering arrester 20 more reliably.
And, top position at kilneye C2, also dispose be fixed on the pit kiln C, as the disperse kilneye cover 103 of anti-locking apparatus of dust, thus, the dust that coking chamber C1 is emitted can be drawn by the high sidewall 103 of this weak point and is directed to dust gathering arrester 20, so the dust of being emitted from the kilneye C2 of pit kiln C almost can be eliminated fully.
Like this, dust gathering arrester 20, be provided with upper guard-plate 23 with described kilneye cover 103 opposite faces, this upper guard-plate 23 has the join posture and leading section and kilneye cover 103 that leading section and kilneye cover 103 join and removes the structure that can change between the releasing posture of joining, thus, under the state of kickoff mechanism 90 and the kilneye C2 opposite face of the coking chamber C1 of manipulating object, state joins the leading section of upper guard-plate 23 and kilneye cover 103 by upper guard-plate 23 being set to join, thus, dust gathering arrester 20 and under shield 24 teamworks, emit regional Z2 by the dust of 103 couples of kilneye C2 of kilneye cover more and be the state that surrounds fully, so, emitted from kilneye C2, with the dust that hot gas flow rises, can be collected by dust gathering arrester 20 reliably.
Like this, when kickoff mechanism 90 moves, remove the state of posture by upper guard-plate 23 being changed to join, can remove joining of 23 pairs of kilneye covers 103 of upper guard-plate, so kickoff mechanism 90 can make upper guard-plate 23 successfully not move with the interference of kilneye cover 103.
The present invention is not limited to the above embodiments, also comprises following content.
