Abstract
The utility model relates to a gasifier cross prevents that stifled ash sweeps device, comprises a housin, the cross that the level that is equipped with in the casing set up, the casing outside is equipped with nitrogen gas provides the device, nitrogen gas provides the device and passes through the connecting pipe connection three -way pipe in the casing, the three -way pipe blows grey spout device through the pipe connection to a plurality of, blow grey spout device with the cross corresponds the setting, blow grey spout unit bit in the top of cross, each it includes a spray tube and one spouts the core to blow grey spout device, the spray tube is just right the cross sets up. On from spray tube spun nitrogen gas direct injection to the cross to clear away the dust on the cross, solved the stifled grey coking phenomenon of cross, this operation need not stop the gasifier operation to gasifier cycle of operation has been prolonged.
Description
Technical field
This utility model relates to a kind of gasification furnace cross anti-blocking ash blow device, for gasification furnace.
Background technology
Because of cross place dust stratification after existing gasifier operation a period of time, and affect gasifier operation, ultimately result in blowing out, when carrying out clearing up, not only waste time and energy, and expense is high.Each blowing out, blow-on direct cost are no less than 1,000,000 yuan.
It is therefore desirable to design a kind of gasification furnace cross anti-blocking ash blow device, to overcome the problems referred to above.
Utility model content
The purpose of this utility model is in that to overcome the defect of existing structure, it is provided that one can extend the gasifier operation cycle, solves the gasification furnace cross anti-blocking ash blow device of cross stifled ash coking phenomenon.
This utility model is achieved in that
This utility model provides a kind of gasification furnace cross anti-blocking ash blow device, including a housing, horizontally disposed cross tee it is provided with in described housing, described hull outside is provided with nitrogen and provides device, described nitrogen provides device to connect the tee T in described housing by connecting tube, described tee T is connected to multiple soot blowing spout device by pipeline, described soot blowing spout device and described cross tee are correspondingly arranged, described soot blowing spout device is positioned at the top of described cross tee, each described soot blowing spout device includes a jet pipe and a spray core, described cross tee is just arranged by described jet pipe.
Further, described nitrogen provides the position that device is connected with described housing to be provided with sleeve pipe.
Further, described nitrogen provides the pipeline that device is connected with described housing to be provided with nitrogen adjustment valve.
Further, the quantity of described tee T is two, and each tee T is connected to two soot blowing spout devices.
Further, the inwall of described housing is provided with water-cooling wall.
Further, described cross tee includes four steel pipes, and four steel pipes are that cross is arranged.
This utility model has the advantages that
Described soot blowing spout device is positioned at the top of described cross tee, and each described soot blowing spout device includes a jet pipe and a spray core, and described cross tee is just arranged by described jet pipe.It is directly injected to cross tee from the nitrogen of jet pipe ejection, thus the dust removed on cross tee, solves cross stifled ash coking phenomenon；This operation need not stop gasification furnace operation, thus extending the gasifier operation cycle.
Accompanying drawing explanation
In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, the accompanying drawing used required in embodiment or description of the prior art will be briefly described below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the premise not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings.
The front view of the gasification furnace cross anti-blocking ash blow device that Fig. 1 provides for this utility model embodiment；
The top view of the gasification furnace cross anti-blocking ash blow device that Fig. 2 provides for this utility model embodiment.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model, rather than whole embodiments.Based on the embodiment in this utility model, all other embodiments that those of ordinary skill in the art obtain under the premise not making creative work, broadly fall into the scope of this utility model protection.
Such as Fig. 1 and Fig. 2, this utility model embodiment provides a kind of gasification furnace cross anti-blocking ash blow device, including a housing 1, is provided with horizontally disposed cross tee 2 in described housing 1, being provided with nitrogen outside described housing 1 and provide device (not shown), nitrogen provides device to be gasification furnace nitrogen header.In this preferred embodiment, the inwall of described housing 1 is provided with water-cooling wall 8.
Such as Fig. 1 and Fig. 2, described nitrogen provides device to connect the tee T 6 in described housing 1 by connecting tube 5, and described nitrogen provides the position that device is connected with described housing 1 to be provided with sleeve pipe 4.Described nitrogen provides the pipeline that device is connected with described housing 1 to be provided with nitrogen adjustment valve 3, for regulating the flow of provided nitrogen.In this preferred embodiment, the quantity of described nitrogen adjustment valve 3 is two, and namely described nitrogen provides device to connect the inside of described housing 1 by two pipelines.
Such as Fig. 1 and Fig. 2, described tee T 6 is connected to multiple soot blowing spout device 7 by pipeline, and described soot blowing spout device 7 is correspondingly arranged with described cross tee 2, and described cross tee 2 includes four steel pipes, four steel pipes are that cross is arranged, and a soot blowing spout device 7 and a steel pipe are correspondingly arranged.Described soot blowing spout device 7 is positioned at the top of described cross tee 2, each described soot blowing spout device 7 includes a jet pipe (i.e. nozzle) and a spray core (controlling the part of internal gas flow), described cross tee 2 is just arranged by described jet pipe, for by nitrogen jet to cross tee 2, thus the dust on cross tee 2 is purged, solve cross stifled ash coking phenomenon.
Such as Fig. 1 and Fig. 2, in this preferred embodiment, the quantity of described tee T 6 is two, and each tee T 6 is connected to two soot blowing spout devices 7.The nitrogen that one opening of described tee T 6 connects outside by connecting tube 5 provides device, and Open Side Down arranges for two other, and is connected to two soot blowing spout devices 7 respectively through pipeline.
In concrete application, nitrogen provides the nitrogen pressure that device provides to be 0.6MP, after installing soot blowing spout device 7 additional, can reach 1.8MP from the nitrogen pressure of jet pipe ejection, it is possible to cross tee 2 tube wall is purged, reaches the purpose of not dust stratification noncoking.
In sum, described gasification furnace cross anti-blocking ash blow device is directly injected on cross tee by the nitrogen sprayed from jet pipe, thus the dust removed on cross tee, solves cross stifled ash coking phenomenon；This operation need not stop gasification furnace operation, thus extending the gasifier operation cycle.
The foregoing is only preferred embodiment of the present utility model; not in order to limit this utility model; all within spirit of the present utility model and principle, any amendment of making, equivalent replacement, improvement etc., should be included within protection domain of the present utility model.
