Description
Technical Field
The utility model relates to a coking technical field, in particular to a device for preventing hardening of dust removal ash of a dust pelletizing system of a dry quenching furnace.
Background
The dust removal ash phenomenon that hardens often appears in dust pelletizing system of dry quenching stove, causes the water-cooling sleeve pipe to arrange the ash not smooth, needs the manual work to clear through the processing, and there is certain potential safety hazard in the clear in-process of high temperature dust removal ash, causes a dust removal fault rate high, and the processing degree of difficulty is big, and is great to putting out the stove normal production influence futilely, and the dust removal ash of once removing dust is not in time handled simultaneously, will aggravate dry coke quenching boiler pipe and circulating fan system wearing and tearing.
Disclosure of Invention
The utility model aims to solve the technical problem that a prevent to put out device that a dust pelletizing system dust removal system of stove hardens futilely, prevent the dust removal burning.
In order to achieve the above object, the utility model adopts the following technical scheme:
a device for preventing hardening of dust removal ash of a primary dust removal system of a dry quenching furnace comprises a primary dust remover, an ash bin, an upper ash bin of a water-cooling sleeve, a lower cooling section of the water-cooling sleeve, a grid valve and an ash conveying scraper; the annular purging pipe is arranged outside the ash bin at the upper part of the water-cooling sleeve and communicated with the ash bin at the upper part of the water-cooling sleeve through a plurality of purging branch pipes, the purging branch pipes are uniformly distributed along the circumference of the periphery of the ash bin at the upper part of the water-cooling sleeve, the annular purging pipe is provided with an air inlet pipe, and the air inlet pipe is respectively connected with a nitrogen pipe and a dry quenching furnace circulating air pipe.
And a support frame is arranged between the annular purging pipe and the outer wall of the ash bin at the upper part of the water-cooling sleeve.
The number of the blowing branch pipes is 3-8.
Compared with the prior art, the beneficial effects of the utility model are that:
the utility model discloses a mode is swept to the dust removal ash in water-cooling sleeve upper portion ash storehouse to the wind and is cooled down, avoids dust pelletizing system dust removal ash to take place the burning and causes the phenomenon that hardens.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a partial plan view of the present invention.
In the figure: the device comprises a primary dust remover 1, an ash bin 2, an upper ash bin 3 of a water-cooling sleeve, a lower cooling section 4 of the water-cooling sleeve, a grid valve 5, an annular blowing and sweeping pipe 7 of an ash conveying scraper 6, a blowing and sweeping branch pipe 8, an air inlet pipe 9, a circulating air pipe 10, a nitrogen pipe 11 and a support frame 12.
Detailed Description
The following description of the embodiments of the present invention will be made with reference to the accompanying drawings:
referring to fig. 1-2, the device for preventing hardening of dust removed by a primary dust removal system of a dry quenching furnace comprises a primary dust remover 1, an ash bin 2, an upper ash bin 3 of a water-cooling sleeve, a lower cooling section 4 of the water-cooling sleeve, a grid valve 5 and an ash conveying scraper 6; an annular purging pipe 7 is arranged outside the ash bin 3 at the upper part of the water-cooling sleeve, the annular purging pipe 7 is communicated with the ash bin 3 at the upper part of the water-cooling sleeve through a plurality of purging branch pipes 8, the purging branch pipes 8 are uniformly distributed along the circumference of the periphery of the ash bin 3 at the upper part of the water-cooling sleeve, and a support frame 12 is arranged between the annular purging pipe 7 and the outer wall of the ash bin 3 at the upper part of the water-cooling sleeve.
An air inlet pipe 9 is arranged on the annular purging pipe 8, and the air inlet pipe 9 is respectively connected with a dry quenching furnace circulating air pipe 10 and a nitrogen pipe 11.
Examples
A device for preventing hardening of dust removal ash of a primary dust removal system of a dry quenching furnace comprises a primary dust remover 1, an ash bin 2, an upper ash bin 3 of a water-cooling sleeve, a lower cooling section 4 of the water-cooling sleeve, a grid valve 5 and an ash conveying scraper 6; the outside in water-cooling sleeve pipe upper portion ash bin 3 is equipped with annular and sweeps pipe 7, and annular sweeps pipe 7 and water-cooling sleeve pipe upper portion ash bin 3 and sweeps branch pipe 8 intercommunication through 6, sweeps branch pipe 8 along water-cooling sleeve pipe upper portion ash bin 3 periphery circumference equipartition, and annular sweeps and is equipped with support frame 12 between pipe 7 and the water-cooling sleeve pipe upper portion ash bin 3 outer wall.
An air inlet pipe 9 is arranged on the annular purging pipe 8, and the air inlet pipe 9 is respectively connected with a dry quenching furnace circulating air pipe 10 and a nitrogen pipe 11. Valves are respectively arranged on the dry quenching furnace circulating air pipe 10 and the nitrogen gas pipe 11. The double-gas-source structure of the circulating air pipe 10 and the nitrogen pipe 11 of the dry quenching furnace avoids the phenomenon of gas interruption.
The dedusting ash in the ash bin at the upper part of the water-cooling sleeve is cooled in an air sweeping mode, and the hardening phenomenon caused by combustion of the dedusting ash of a dedusting system is avoided.
Above utility model, to the ordinary technical personnel in this technical field, can also be right without deviating from the principle of the utility model, these improve and decorate and also fall into the protection scope of the utility model claims. The above description is only the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can substitute or change the technical solution and the concept of the present invention within the technical scope disclosed in the present invention.
