Abstract
The utility model relates to a dry coke quenching oven nitrogen-charging device, comprising a main nitrogen input pipe. The main nitrogen input pipe is connected with an annular pipeline, and the annular pipeline is provided with a plurality of nozzles. The diameters of the nozzles are different, and the diameters of the nozzles near the main nitrogen input pipe is larger than that of the nozzles far from the main nitrogen input pipe. The dry coke quenching oven nitrogen-charging device is arranged at the lowest bottom of a dry coke quenching oven. The dry coke quenching oven nitrogen-charging device can enhance evenness and effectiveness for charging nitrogen when a circulation fan stops operating due to fault, the temperature of coke in a cooling chamber is distributed lengthways and reasonably, and self-igniting phenomena due to the downward movement of the high-temperature zone of coke in the cooling chamber is avoided.
Description
Technical field
The utility model relates to a kind of dry quenching(of coke) stove nitrogen charging device, specifically, relates to a kind of dry quenching(of coke) stove nitrogen charging device.
Background technology
The dry quenching(of coke) stove generally all is the bigger close jar of volume.As shown in Figure 1, be the structural representation of dry quenching(of coke) stove.Its epimere is the chamber 1 ' that prestores, and indoor all is red Jiao; The stage casing is annular flue 2 '; Hypomere is a cooling room 3 ', indoor coke from top to down, temperature is more and more lower, the temperature that T4 is ordered in the ordinary production is controlled at below 450, the temperature that T3 is ordered is controlled at below 300.In daily production, in case recirculation blower 4 ' fault stops, the coke high-temperature zone will successively move down in the stove; Again because of the temperature difference of every coke charge in the stove, lowly down highly, formed air-flow naturally and upwards flowed, the bottom produces the situation of negative pressure, and under the relatively poor situation of recycle system tightness, air sucks, and has accelerated the rising of cooling room 3 ' temperature.According to the daily knowhow of dry quenching(of coke) stove, when coke temperature reaches 450 ℃, as long as there is free aspiration to go into, spontaneous combustion will take place in coke.
Under dry quenching(of coke) stove blower fan 5 ' shutdown situation, can open automatically towards nitrogen point 4 ' and to fill the nitrogen operation.But its go into the stove zone dried to put out the stove diameter bigger, so its nitrogen amount far can not stop the coke high-temperature zone of shutting down under the prerequisite to move down phenomenon; Secondly, below 7 ', also there is about 50 tons coke, the nitrogen cooling that this part of coke can't be charged in blast cap and peripheral air channel.
The dry coke quenching discharge mode that adopts mainly contains flashboard type interruption coke discharging mode at present, and its control mode is for to be provided with hydraulic transmission equipment in the outside of gate housing, and this hydraulic transmission equipment is temperature influence not.After coke generation spontaneous combustion, the positive opening gate has been arranged red Jiao in the stove by discharger 6 ', and red Jiao of discharge extinguishes with fire water.Although can avoid the dried stove that puts out to sustain damage, treating processes danger is very big, and repairing will have a strong impact on production output with the time in a week afterwards.
Dry coke quenching discharge mode also has the continuous coke discharging mode of rotary seal valve, and its control mode is to adjust the solenoid of vibratory feeder, and this equipment is subjected to temperatures involved in vibratory feeder housing the inside.When the coke generation nature of cooling room, the solenoid of vibratory feeder damages because of being heated, and the so dried coke that puts out in the stove will have been arranged, and the result not only burns out discharger 6 ', influences output, and the dried stove that puts out also will be damaged.
Summary of the invention
The purpose of this utility model is to provide a kind of dry quenching(of coke) stove nitrogen charging device, it can hinder when shutting down for some reason at recirculation blower, improve the homogeneity and the validity of filling nitrogen, reach that coke temperature rationally distributes longitudinally in the cooling room, avoid cooling room internal cause coke high-temperature zone to move down and dieseling takes place.
For achieving the above object, the dry quenching(of coke) stove nitrogen charging device that the utility model provides, it comprises nitrogen input house steward, and characteristics are, and this nitrogen is imported total pipe coupling one pipeline that goes in ring, and this belt pipeline is provided with plurality of nozzles.
The diameter difference of described nozzle, the nozzle diameter near from nitrogen input house steward is bigger than import house steward's nozzle far away from nitrogen.
Described dry quenching(of coke) stove nitrogen charging device is installed the dried bottommost that puts out stove.
The utility model is installed in dried bottom of putting out stove, and surface-area is very little, is convenient to charge into the reasonable distribution of nitrogen.When shutting down, uses by recirculation blower the utility model, the nitrogen of nozzle ejection is vertical distribution trend of controlled chilling chamber coke temperature effectively, prevent from spontaneous combustion to take place because of the coke heat zone moves down, simultaneously, the nozzle diameter near from nitrogen input house steward is bigger than import house steward's nozzle far away from nitrogen, and nitrogen is evenly sprayed.The utility model also plays the effect that stops air to suck, and helps the dried fire grate that puts out and goes out the safe in utilization of device.
Description of drawings
Fig. 1 is the structural representation of dry quenching(of coke) stove;
Fig. 2 is a structural representation of the present utility model.
Embodiment
Below with reference to the accompanying drawings 2, better embodiment of the present utility model is described.
As shown in Figure 2, the structural representation of the dry quenching(of coke) stove nitrogen charging device 1 that provides for the utility model.It comprises nitrogen input house steward 11, and this nitrogen input house steward 11 connects a belt pipeline 12, and this belt pipeline 12 is provided with four nozzles 131,132,133,134 that become 90 ° of distributions.
Nozzle 131,132,133,134 diameter difference will be greatly than from nitrogen input house steward nozzle 133,134 far away from nitrogen input house steward 11 near nozzle 131,132 diameters.
This dry quenching(of coke) stove nitrogen charging device 1 is installed the dried bottommost that puts out stove.Surface-area is very little, is convenient to charge into the reasonable distribution of nitrogen.When shutting down, uses by recirculation blower the utility model, the nitrogen of nozzle ejection is vertical distribution trend of controlled chilling chamber coke temperature effectively, prevent from spontaneous combustion to take place because of the coke heat zone moves down, simultaneously, the nozzle diameter near from nitrogen input house steward is bigger than import house steward's nozzle far away from nitrogen, and nitrogen is evenly sprayed.The utility model also plays the effect that stops air to suck, and helps the dried fire grate that puts out and goes out the safe in utilization of device.
