Abstract
The utility model discloses a dust removing device for a boiler flue. The dust removing device is characterized by comprising a steam soot blowing device arranged at a position of the outer wall of a boiler hearth. Soot is easily accumulated at the position, the steam soot blowing device is provided with a telescopic and rotatable soot blowing gun barrel, and part of the soot blowing gun barrel extends into the boiler hearth. By the aid of the technical scheme, the steam soot blowing device is additionally mounted outside the hearth corresponding to the position of the dust removing device for the boiler flue, a telescopic and rotatable soot blowing gun enters the hearth, and the dust removing device has the advantages that steam is sprayed to realize continuous impact, the accumulated soot and bonded slag are removed, and the like.
Description
Technical field
The utility model relates to chemical field, particularly a kind of boiler flue dust arrester.
Background technology
The dust stratification slagging scorification is the ubiquitous problems of various boilers, and is very big for economy, the safety effects of boiler operatiopn.The collecting ash slagging scorification brought, and immediate problem is to cause the heat exchange efficiency of boiler to descend.At present; The soot blower that generally uses is sonic soot blowing; Utilize sound wave and soot particle and dust stratification that vibration and resonance take place, thereby reach the purpose of deashing, its shortcoming is: the dedusting scope is little, the erecting bed number is many, the maintenance frequent; Actual production is in service, and often boiler working condition is not unstable, tubulation dust stratification booster because of dedusting effect does not significantly cause, and overtemperature is on the low side etc.
Summary of the invention
To the problems referred to above, the purpose of the utility model is to provide the boiler flue that a kind of dedusting effect is good, the purging scope is big dust arrester.
For achieving the above object; The technical scheme that the utility model proposed is: a kind of boiler flue dust arrester; It is characterized in that: comprise and be located at the steam soot-blower that the boiler furnace outer wall is prone to the dust stratification position; Described steam soot-blower is provided with the ash gun pipe of a scalable rotation, and described ash gun tube portion stretches into boiler furnace.
Further, described steam soot-blower also comprises transmission mechanism, roller frame parts, hanger rod part, and described steam soot-blower is fixed in the boiler furnace outer wall through the holder hanger rod part.
Adopt technique scheme; The described boiler flue dust arrester of the utility model is through installing steam soot-blower additional outside being prone to the corresponding burner hearth in dust stratification position; Utilize the ash gun of scalable rotation to get into burner hearth, have ejection steam and continue to impact, advantage such as removing dust stratification and slagging scorification are effective.
Description of drawings
Fig. 1 is installed on the outer sketch map of boiler furnace for the described stove flue of the utility model dust arrester;
Fig. 2 is the described steam soot-blower sketch map of the utility model;
Wherein: 1. warm economizer in boiler, 11. high temperature superheaters, 12. low temperature superheaters, 13. high-temperature economizers, 14., 15. low-level (stack-gas) economizers, 2. steam soot-blower, 21. transmission mechanisms, 22. ash gun pipes, 23. roller frame parts, 24. hanger rod parts.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment, the utility model is further specified.
Like Fig. 1, shown in Figure 2; A kind of boiler flue dust arrester; Comprise and be located at the steam soot-blower 2 that boiler 1 hearth outer wall is prone to the dust stratification position; The ash gun pipe 22 that steam soot-blower 2 is provided with a scalable rotation stretches into boiler 1 burner hearth, and steam soot-blower 1 also comprises transmission mechanism 21, roller frame parts 23, hanger rod part 24, and described steam soot-blower 1 is fixed in boiler 1 hearth outer wall through hanger rod part 24; As shown in Figure 1, the easy dust stratification position of the installing steam soot-blower of present embodiment is on the high temperature superheater 11 of boiler 1, low temperature superheater 12 and 13 of high-temperature economizers, high- temperature economizer 13 and 14 in middle temperature economizer, low-level (stack-gas) economizer 15 downsides.
Adopt technique scheme; The described boiler flue dust arrester of the utility model is through installing steam soot-blower additional outside being prone to the corresponding burner hearth in dust stratification position; Utilize the ash gun pipe of scalable rotation to stretch into burner hearth, ejection steam continues to impact, and removes dust stratification and slagging scorification.The length of ash gun pipe is that the nozzle track is a helix according to the furnace depth design, and the purging scope is big.The shower nozzle part of removing gun barrel when stopping using is in the furnace wall protective sleeve, and all outside furnace wall, gun barrel can the too high distortion of Yin Wendu for all the other.Use the back gas forming amount to increase, bring up to about 430 degree about overtemperature is spent by 405, exhaust gas temperature is reduced to 125 degree.
Although specifically show and introduced the utility model in conjunction with preferred embodiment; But the those skilled in the art should be understood that; In the spirit and scope of the utility model that does not break away from appended claims and limited; In form with on the details the utility model is made various variations, be the protection domain of the utility model.
Claims (2)
