Description
Technical Field
The utility model relates to the technical field of boiler bottom slag ash removal, in particular to a dust removal device applied to a slag cooler and a slag conveying belt.
Background
The amount and performance of ash produced by a power plant varies significantly due to the nature of the fuel and the combustion process. In addition, various desulfurizing agents or NOx removing agents are often added into the circulating fluidized bed, and a large amount of substances such as calcium oxide, calcium sulfate and the like are contained in ash residues. Under the condition of large ash quantity, a large amount of fine ash can be contained in the bottom slag of the boiler, and the conditions of fine ash escape, ash leakage and the like are easy to occur, so that the environment around slag removing equipment is polluted.
Disclosure of Invention
In order to solve the problem of environmental pollution caused by fine ash escape in the existing bottom slag, the utility model provides a dust removing device applied to a slag cooler and a slag conveying belt, which can effectively reduce the leakage of fine ash escape so as to avoid pollution around slag discharging equipment.
The technical scheme is as follows: be applied to cold sediment machine and defeated sediment belt's dust collector, it is including the cold sediment machine of connecting the boiler, cold sediment machine below is provided with defeated sediment belt machine, its characterized in that, the last outlet pipe of the slag tap body of cold sediment machine connects the dust cover, the dust cover is located the belt top of defeated sediment belt machine, the dust cover with the dust removal pipeline is all connected at the slag tap body top of cold sediment machine, the afterbody flue is connected to the dust removal pipeline.
The dust cover is arranged above the conveying end of the slag conveying belt conveyor;
a gate valve is arranged at the joint of the dust removal pipeline and the tail flue;
gate valves are arranged between the dust cover and the dust removing pipeline and between the slag tapping machine body and the dust removing pipeline;
the dust removing pipeline is arranged above the slag cooler.
After the utility model is adopted, fine ash generated by ash residues in the slag cooling machine and the slag conveying belt conveyor can be sucked into the tail flue through the dust removing pipeline, the dust cover can prevent the fine ash from diffusing outwards, the fine ash is easier to collect and suck away, the escaping condition can not occur, and the pollution around slag discharging equipment is avoided.
Drawings
FIG. 1 is a front view of the present utility model;
FIG. 2 is a top view of the present utility model;
FIG. 3 is a schematic diagram of a slag cooler.
Detailed Description
See fig. 1, fig. 2 and fig. 3 show, a dust collector for cold slag machine and defeated sediment belt, it is including the cold slag machine 2 of connecting boiler 1, cold slag machine 2 side by side interval arrangement is two in this embodiment, cold slag machine 2 is including advancing sediment organism 2-1, barrel 2-2 and slag tap organism 2-3, cold slag machine 2 below is provided with defeated sediment belt 3, the exit tube of slag tap organism 2-3 bottom is connected dust cover 4, the tip of defeated sediment belt 3 also is provided with dust cover 4, dust cover 4 and the dust removal pipeline 5 is all connected at the slag tap organism 2-3 top of cold slag machine 2, dust removal pipeline 5 connects afterbody flue 6. In the figure, 9 is a slag bin, and the waste slag discharged by the slag cooler 2 is sent to the slag bin 9 through the slag conveying belt conveyor 3.
A first gate valve 7 is arranged at the joint of the dust removal pipeline 5 and the tail flue 6; a second gate valve 8 is arranged between the dust cover 4 and the dust removing pipeline 5 and between the slag tapping machine body 2-3 and the dust removing pipeline 5; because of the large pressure difference between the tail flue 6 and the slag cooler 2, the ash flow rate in the dust removing pipeline 5 is large, and the abrasion to the pipe fitting is large, so that a pipe made of wear-resistant ceramic materials is needed.
The dust removing pipeline 5 is arranged above the slag cooler 2.
The working principle is as follows: the boiler 1 has produced the lime-ash in the operation process, and on the lime-ash was discharged to defeated sediment belt feeder 3 after cold sediment machine 2 cooling, the lime-ash can all produce some fine ash in cold sediment machine 2 and on conveyer belt feeder 3, because be the negative pressure in the afterbody flue 6, the fine ash of production is inhaled in the afterbody flue 6 after passing through dust removal pipeline 5, can enter into the dust remover at the back in the back together according to the flue gas in the afterbody flue 6 and remove dust to the condition that fine ash escaped the hourglass has been reduced, pollution around the slag discharging equipment has been avoided.
