Description
Technical field
This utility model belongs to boiler technology field, cleans double-cyclone coal gas burner device online particularly to one.
Background technology
At present in clean burn gas boiler and blending gas boiler, double-cyclone gas burner is widely used.This kind of burner is relatively easy due to structure, fuel gas and air mixability are higher, catch fire stable, power is big, efficiency of combustion is high, but this style of burner is big due to design resistance, and spinning disk angle and spinning disk installation site are relatively fixed, and user cannot be from Row sum-equal matrix, therefore, this kind of burner only adapts to the cleaner gaseous fuel that burns；Its fuel type mainly has: blast furnace gas, coke-stove gas and coal gas of converter.In actual use, it has been found that due to many factors, above-mentioned fuel is caused to there is two categories below outstanding problem: one is that coal gas sidespin flow clogging is serious；Two is that coal gas sidespin flow is fragile, boiler continuous operating time is restricted, boiler output declines, boiler safety stable operation also can be affected time serious, a lot of use unit is caused to be forced the frequent blowing out of short cycle, need to expend and be manually entered burner hearth cleaning burner in a large number, simultaneously because seriously corroded, the use cycle time of burner, need to often change burner, cause spare part expense too high.
Summary of the invention
The purpose of this utility model to solve above-mentioned technical problem.
The purpose of this utility model is achieved in that online cleaning double-cyclone coal gas burner device, including compressed air arm, come arm, burner hearth, it is characterized in that: after described compressed air arm is in parallel with carrying out arm, access purge circuit house steward, purge circuit house steward divides two-way to pick out, one tunnel is connected with upper row's burner purge circuit arm after connecing stop valve again, and another road is connected with lower row's burner purge circuit arm after connecing stop valve again；After upper row's burner purge circuit arm connects stop valve, a point two-way picks out, one tunnel connects the right half spinning disk purge circuit arm of burner, the other end of the right half spinning disk purge circuit arm of burner is connected by the right half spinning disk distribution endless tube of stop valve and burner, and the other end of the right half spinning disk distribution endless tube of burner is provided with two spinning disk purge nozzle；Another road connects the left half spinning disk purge circuit arm of burner, the other end of the left half spinning disk purge circuit arm of burner is connected by the left half spinning disk distribution endless tube of stop valve and burner, and the other end of the left half spinning disk distribution endless tube of burner is provided with two spinning disk purge nozzle, leaves gap between spinning disk purge nozzle and burner hearth.
After described lower row's burner purge circuit arm connects stop valve, a point two-way picks out, one tunnel connects the right half spinning disk purge circuit arm of burner, the other end of the right half spinning disk purge circuit arm of burner is connected by the right half spinning disk distribution endless tube of stop valve and burner, and the other end of the right half spinning disk distribution endless tube of burner is provided with two spinning disk purge nozzle；Another road connects the left half spinning disk purge circuit arm of burner, the other end of the left half spinning disk purge circuit arm of burner is connected by the left half spinning disk distribution endless tube of stop valve and burner, and the other end of the left half spinning disk distribution endless tube of burner is provided with two spinning disk purge nozzle.
This utility model is rational in infrastructure, the blocking of energy Hand scarf Dual-cyclone combustor spinning disk, and the continuous cycle of operation of burner can be made to increase substantially；On-line operation is simple to operate, and system maintenance amount is little；Extending the boiler operatiopn cycle, reduce operation and maintenance cost, popularization and application have good economic and social benefit.
