Abstract
The utility model discloses a discharging and dust removing device for a slag warehouse of a circulating fluidized bed boiler, which comprises an air inlet pipe, a cyclone separator and a discharging chute; the air inlet pipe is arranged on a slag discharging port of the slag warehouse; more than 8 air suction holes are uniformly distributed on the wall of the air inlet pipe along the circumference; the suction hole is communicated with the air inlet of the cyclone separator through a pipeline, the air outlet of the cyclone separator is communicated with the air inlet of the bag-type dust collector at the top of the slag bin through a pipeline, the dust outlet at the bottom of the cyclone separator is communicated with one end of the discharging chute, and the other end of the discharging chute is arranged below the slag tap. Has the advantages that: compared with the slag discharging and dust removing device of the slag warehouse of the circulating fluidized bed boiler, the slag discharging and dust removing device can reduce dust pollution under the condition of not using water, has high dust removing effect, saves water resources, improves the working environment of workers, and does not influence the comprehensive utilization of the future slag.
Description
The technical field is as follows:
the utility model relates to a dust collector especially relates to a dust collector of unloading of circulating fluidized bed boiler slag storehouse.
Background art:
the circulating fluidized bed boiler burns low-heat value coal to generate a large amount of ash slag, generates larger dust during ash discharge, causes serious pollution to the environment, causes serious threat to the body health of on-site slag discharge personnel, and is particularly important for achieving good and bad dust removal effect during slag discharge.
Because the granularity of the bottom slag of the circulating fluidized bed unit is larger than 50 percent of 1mm, the direct connection dust remover is seriously blocked, and the cloth bag dust removal cannot be realized, the existing dust removal method for slag discharge of the circulating fluidized bed boiler is water spraying dust removal, the dust removal is incomplete, a large amount of precious water resources are required, and meanwhile, when the condition that the aluminum content of the ash slag is high is met, the spraying can influence the comprehensive utilization of the later ash slag.
The utility model has the following contents:
an object of the utility model is to provide a circulating fluidized bed boiler slag storehouse dust collector of unloading that can reduce dust pollution under the condition of not using water.
The utility model discloses by following technical scheme implement: a discharging and dust removing device for a slag bin of a circulating fluidized bed boiler comprises an air inlet pipe, a cyclone separator and a discharging chute; the air inlet pipe is arranged on a slag discharging port of the slag warehouse; more than 8 air suction holes are uniformly distributed on the wall of the air inlet pipe along the circumference; the suction hole is communicated with the air inlet of the cyclone separator through a pipeline, the air outlet of the cyclone separator is communicated with the air inlet of the bag-type dust collector at the top of the slag bin through a pipeline, the dust outlet at the bottom of the cyclone separator is communicated with one end of the discharging chute, and the other end of the discharging chute is arranged below the slag tap.
Preferably, a stop valve is arranged on a pipeline between the air outlet of the cyclone separator and the air inlet of the bag-type dust collector.
The utility model has the advantages that: compared with the slag discharging and dust removing device of the slag warehouse of the circulating fluidized bed boiler, the slag discharging and dust removing device can reduce dust pollution under the condition of not using water, has high dust removing effect, saves water resources, improves the working environment of workers, and does not influence the comprehensive utilization of the future slag.
Description of the drawings:
fig. 1 is a schematic view of the overall structure of the present invention.
Fig. 2 is a schematic structural view of an air inlet duct.
The device comprises an air inlet pipe 1, an air suction hole 11, a cyclone separator 2, a discharge chute 3, a slag storage 4, a slag discharge port 41, a bag-type dust remover 42, a stop valve 5 and a slag pulling vehicle 6.
The specific implementation mode is as follows:
example (b): as shown in fig. 1 and 2, the slag storage discharging and dedusting device of the circulating fluidized bed boiler comprises an air inlet pipe 1, a cyclone separator 2 and a discharging chute 3; the air inlet pipe 1 is arranged on a slag tap 41 of the slag storage 4; 8 air suction holes 11 are uniformly distributed on the wall of the air inlet pipe 1 along the circumference; the air suction hole 11 is communicated with an air inlet of the cyclone separator 2 through a pipeline, an air outlet of the cyclone separator 2 is communicated with an air inlet of a bag-type dust remover 42 at the top of the slag storage 4 through a pipeline, and the bag-type dust remover 42 provides negative pressure for the cyclone separator 2 so as to extract dust in ash in the air inlet pipe 1; the pipeline of the air outlet of the cyclone separator 2 and the air inlet of the bag-type dust collector 42 is provided with a stop valve 5, the stop valve 5 controls the start and stop of the cyclone separator 2 for dust removal, one end of the discharging chute 3 at the dust outlet at the bottom of the cyclone separator 4 is communicated, and the other end of the discharging chute 3 is arranged below the slag tap 41.
Instructions for use: when slag is discharged from the slag storage 1, ash falls from the slag discharge port 41 and passes through the air inlet pipe 1, and dust in the ash enters the cyclone separator 2 for gas-solid separation; the large solid particles separated from the dust fall into a slag-pulling vehicle 6 below a slag-discharging opening 41 through a discharging chute 3; the fine dust which cannot be separated by the cyclone separator 2 in the dust enters the bag-type dust collector 42 for secondary dust collection.
Claims (2)
1. A discharging and dedusting device for a slag warehouse of a circulating fluidized bed boiler is characterized by comprising an air inlet pipe, a cyclone separator and a discharging chute; the air inlet pipe is arranged on a slag discharging port of the slag warehouse; more than 8 air suction holes are uniformly distributed on the wall of the air inlet pipe along the circumference; the suction hole is communicated with the air inlet of the cyclone separator through a pipeline, the air outlet of the cyclone separator is communicated with the air inlet of the bag-type dust collector at the top of the slag bin through a pipeline, the dust outlet at the bottom of the cyclone separator is communicated with one end of the discharging chute, and the other end of the discharging chute is arranged below the slag tap.
2. The circulating fluidized bed boiler slag warehouse discharging and dedusting device as claimed in claim 1, wherein a stop valve is arranged on a pipeline between the air outlet of the cyclone separator and the air inlet of the bag-type dust collector.
