Abstract

The utility model relates to a steam soot-blower, which comprises a pipeline 2, a valve 3, a pipeline 4, a valve 5, a pipeline 5, a pipeline 6, a valve 7, a pipeline 8, a first T-shaped nozzle 9, a pipeline 10, and a second T-shaped nozzle 11. The utility model is characterized in that: the upper part of the pipeline 2 is connected with a steam pocket 1 on the boiler, while the lower part is connected with the valve 3; the valve 3 is connected with the valve 5 through the pipeline 4; the valve 5 is connected with the pipeline 10; the second T-shaped nozzle 11 is connected with the end of the pipeline 10; in addition, the pipeline 4 is also connected with the pipeline 6 which is connected with the valve 7; the valve 7 is connected with the pipeline 8, the end of which is connected with the first T-shaped nozzle 9. The first T-shaped nozzle is designed to remove the ash deposition in the super-heater, while the second T-shaped nozzle is designed to remove the ash fouling in the coal economizer. The utility model has the advantages that the device can be directly extended into the coal economizer and the super-heater to purge the inner surfaces thereof; the purging result is fairly good; since no furnace shutdown is required, the production is not affected. Thus the utility model is an ideal steam soot-blower for cleaning up coal economizers and super-heaters of power generating steam boilers.

Description

Steam sootblower

One, technical field

The utility model relates to a kind of dust remover, particularly a kind of economizer of generation driving force steam boiler, the steam sootblower of superheater.

Two, background technology

At present, the generation driving force steam boiler in power plant is after operation a period of time, economizer, superheater surface can be amassed the last layer black dirt, have influenced economizer greatly, the endothermic effect of superheater, many heat energy have been slatterned in vain, and this situation is risen as can be seen by exhaust gas temperature.On cleaning dust stratification problem, many power plant all do not have concrete scheme, even the operation of many small power plants all do not clear up in 2 years, and this is a waste greatly to fuel obviously, and this is the defective of prior art.

Three, summary of the invention

The purpose of this utility model is the economizer of a kind of generation driving force steam boiler of design, the steam sootblowers of superheater, and the dust stratification in order to cleaning economizer, superheater overcomes the steam boiler economizer in present power plant, the defective that the superheater dust stratification can't be cleared up.

The purpose of this utility model can reach by following embodiment: this soot blower utilizes boiler steamdrum saturated vapor to originate as steam, form by pipeline 2, valve 3, pipeline 4, valve 5, pipeline 6, valve 7, pipeline 8, T-shaped shower nozzle first 9, pipeline 10, T-shaped shower nozzle second 11, it is characterized in that the steamdrum 1 on pipeline 2 tops and the boiler joins, bottom and valve 3 join, valve 3 joins by pipeline 4 and valve 5, valve 5 joins with pipeline 10, and pipeline 10 ends connect T-shaped shower nozzle second 11; In addition, pipeline 4 goes back and pipeline 6 joins, and pipeline 6 joins with valve 7, and valve 7 is taken over roads 8, and pipeline 8 ends connect T-shaped shower nozzle first 9; T-shaped shower nozzle first is used to clear up the dust stratification in the superheater, and T-shaped shower nozzle second is used to clear up the dust stratification in the economizer.

Advantage of the present utility model for can directly stretch into economizer, superheater is indoor that its surface is purged, and is respond well, and without blowing out, do not influence production, the effect of this soot blower cleaning dust stratification can descend 30 ℃ from exhaust gas temperature and significantly find out.

Four, description of drawings

Below in conjunction with accompanying drawing the utility model is described in further detail.

Fig. 1 is an overall structure schematic diagram of the present utility model

Five, the specific embodiment

As shown in Figure 1, this soot blower utilizes the saturated and steam of boiler steamdrum 1 to originate as steam, by forming by pipeline 2, valve 3, pipeline 4, valve 5, pipeline 6, valve 7, pipeline 8, T-shaped shower nozzle first 9, pipeline 10, T-shaped shower nozzle second 11, it is characterized in that the steamdrum 1 on pipeline 2 tops and the boiler joins, bottom and valve 3 join, valve 3 joins by pipeline 4 and valve 5, and valve 5 joins with pipeline 10, and pipeline 10 ends connect T-shaped shower nozzle second 11; In addition, pipeline 4 goes back and pipeline 6 joins, and pipeline 6 joins with valve 7, and valve 7 is taken over roads 8, and pipeline 8 ends connect T-shaped shower nozzle first 9.T-shaped shower nozzle first 9 is used to clear up the dust stratification in the superheater 12, and T-shaped shower nozzle second 11 is used to clear up the dust stratification in the economizer 13.
