Wherein, the value of a can make-1, 2, 4 etc., as long as when #N carbonizing chamber is coaling, #N+a carbonizing chamber is in the coking later stage, and | a| represents the absolute value of a, be connected with #N+a carbonizing chamber by smoke guiding bogie when #N carbonizing chamber is coaling, the flue dust produced of being coaling by #N carbonizing chamber imports #N+a carbonizing chamber, and because in each carbonizing chamber | a| I group carbonizing chamber 5 and | the interlaced arrangement of a| II group carbonizing chamber 6, so when #N carbonizing chamber is I group carbonizing chamber 5, #N+a carbonizing chamber must be II group carbonizing chamber 6, and when #N carbonizing chamber is II group carbonizing chamber 6, #N+a carbonizing chamber must be I group carbonizing chamber 5, that is, to I group carbonizing chamber 5 coaling produce flue gas be imported into II group carbonizing chamber 6 by smoke guiding bogie 7, and to II group carbonizing chamber 6 coaling produce flue gas be imported into I group carbonizing chamber 5 by smoke guiding bogie 7.Such as, shown in Fig. 2, N carbonizing chamber flue dust is imported the ammoniacal liquor system layout of N+2 carbonizing chamber, in figure, tamping coke furnace has carbonizing chamber #1, #2, #3, #4, #5, #6, #7, #8, #9, #10 ... I group carbonizing chamber 5 can be #3, #4, #7, #8 ... they are all connected with the first ammonia water pipe 101, now, II group carbonizing chamber 6 is #1, #2, #5, #6, #9, #10 ... they are connected with the second ammonia water pipe 201; Certain I group carbonizing chamber 5 can be #1, #4, #5, #8, #9 ..., so now, #2, #3, #6, #7, #10, #11 ... be II group carbonizing chamber 6.
And when a gets-1, I group carbonizing chamber 5 and II group carbonizing chamber 6 are be numbered the carbonizing chamber of odd number and be numbered the carbonizing chamber of even numbers respectively.
I group carbonizing chamber 5 is supplied separate with the high pressure aqua ammonia of II group carbonizing chamber 6, and both when coalingging, have phase mutual conductance cigarette, that is, the carbonizing chamber of coalingging and be now be separate all the time for leading the high pressure aqua ammonia supply of the carbonizing chamber of cigarette, thus can not have an impact mutually.
In the prior art, because each carbonizing chamber is coaling, interval time is shorter, for ensureing to supply ammoniacal liquor in time when coalingging, ammonium hydroxide delivery pump is in continuous constant pressure running status all the time, this just causes the waste of electric energy, for addressing this problem, as optimal way, the drive-motor of described first ammonium hydroxide delivery pump 1 and the second ammonium hydroxide delivery pump 2 is variable-frequency motor, and described first ammonium hydroxide delivery pump 1 is all connected with coaling operation controller 3 with the drive-motor of the second ammonium hydroxide delivery pump 2.
Under the control of coaling operation controller 3, when non-coaling operation, the first ammonium hydroxide delivery pump 1 and the second ammonium hydroxide delivery pump 2 is made to be in low-speed run state, thus saves energy, also protect the stability of pump machine envelope simultaneously.And when coaling operation, making the first ammonium hydroxide delivery pump 1 and the second ammonium hydroxide delivery pump 2 be in high-speed cruising state, its pressure-controlling is as the criterion being in micro-vacuum state with the coal port flue dust of the carbonizing chamber of coalingging.So, just power consumption can greatly have been saved.
For preventing the first ammonia water pipe 1 and the second ammonia water pipe 2 from having an accident because ammonia pressures is excessive, as optimal way, described first ammonia water pipe 101 being connected with the first safety valve 102, described second ammonia water pipe 201 is connected with the second safety valve 202.
Safety valve is a kind of safeguard protection valve; its opening and closing element is in normally off by under External Force Acting; when the pressure medium in equipment or pipeline raises, automatically open when exceeding prescribed value, exceed specified value by preventing pressure medium in pipeline or equipment to discharge medium outside system.After being provided with safety valve, just can guarantee that the ammonia pressures of the first ammonia water pipe 101 and the second ammonia water pipe 201 is all the time within security value (s).
Because ammonium hydroxide delivery pump is in continuous running status, so easily break down, if ammonium hydroxide delivery pump breaks down, then can cause ammoniacal liquor systemic breakdown, for addressing this problem, as optimal way, this high pressure aqua ammonia Operation system setting for tamping coke oven dust has the first ammonium hydroxide delivery pump 103 for subsequent use and the second ammonium hydroxide delivery pump 203 for subsequent use, described first ammonium hydroxide delivery pump 103 for subsequent use is connected with the first ammonia water pipe 101 by the first stand-by pump valve 105, described second ammonium hydroxide delivery pump 203 for subsequent use is connected with the second ammonia water pipe 201 by the second stand-by pump valve 205, the ammoniacal liquor output port place of described first ammonium hydroxide delivery pump 1 is provided with the first main pump valve 104, the ammoniacal liquor output port place of described second ammonium hydroxide delivery pump 2 is provided with the second main pump valve 204.
When the first ammonium hydroxide delivery pump 1 breaks down, just can close the first main pump valve 104, open the first stand-by pump valve 105, the first ammonium hydroxide delivery pump 103 for subsequent use is made to replace the first ammonium hydroxide delivery pump 1 to work, equally, when the second ammonium hydroxide delivery pump 2 has fault, then the second main pump valve 204 can be closed, open the second stand-by pump valve 205, make the second ammonium hydroxide delivery pump 203 for subsequent use replace the second ammonium hydroxide delivery pump 2 to work.
And be the situation that the stand-by pump solving main pump and this main pump all goes wrong, as optimal way, between described first ammonia water pipe 101 and the second ammonia water pipe 201, be connected with communicating valve 4.
Such as, when the first ammonium hydroxide delivery pump 1 and the first ammonium hydroxide delivery pump 103 for subsequent use all break down, then communicating valve can be opened, close the first main pump valve 104 and the first stand-by pump valve 105, use the second ammonium hydroxide delivery pump 2 to supply ammoniacal liquor to the first ammonia water pipe 101 and the second ammonia water pipe 201 simultaneously, although, so there will be the fluctuation of ammonia spray terminal pressure, in case of emergency can use reluctantly.By arranging ammonium hydroxide delivery pump for subsequent use and communicating valve 4 can provide double insurance for ammonia spray, race against time to greatest extent for repair provides.
In addition, because coaling in process, raw gas generation increases along with the amount increase entering carbonizing chamber of briquette, if open high pressure aqua ammonia too early, certainly will absorb large quantity of air like this enters raw gas system, causes oxygen content of crude gas to increase, and affects subsequent production.For addressing this problem, as optimal way, be connected with coaling operation controller 3 respectively with the oil cylinder of the second T-valve 106 for controlling the first T-valve 106.
So, accurately can control the first T-valve 106 and the second T-valve 206 opening/closing time by coaling operation controller 3, thus prevent from opening high pressure aqua ammonia too early, suck a large amount of outside air.During concrete control, the T-valve opening time of carbonizing chamber of coalingging is more adjacent leads the T-valve opening time of cigarette carbonizing chamber early, and the concrete opening time of high pressure aqua ammonia is in micro-vacuum state with carbonizing chamber mouth and is as the criterion.This avoid raw gas system oxygen level to exceed standard.
For convenience of maintenance, as optimal way, between described first T-valve 106 and the first ammonia water pipe 101, be provided with the first ball valve 107, between described second T-valve 206 and the second ammonia water pipe 201, be provided with the second ball valve 207.When normally running, the first ball valve 107 and the second ball valve 207 are all in normally open, and if ammoniacal liquor system malfunctions, then they can be closed, thus convenient maintenance.
