Abstract
The utility model relates to a deslagging and dedusting device of a slag cooler for a boiler. The deslagging and dedusting device comprises a slag cooler (2) connected with a boiler (1), wherein a slag inlet (3) of the slag cooler (2) is connected with a deslagging port (4) of the boiler (1), and a slag outlet (5) is arranged on the slag cooler (2). The deslagging and dedusting device is characterized by further comprising a dust suction inlet (6) arranged above the slag outlet (5), and the dust suction inlet (6) is provided with a pipeline (7) which is communicated with a dust outlet (8). The deslagging and dedusting device has the benefits as follows: the dust suction inlet, the pipeline and the dust outlet which are communicated with a flue of the boiler are arranged at the slag outlet of the slag cooler, so that fine ash and dust which are produced during deslagging are discharged from the flue of the boiler, the problem of secondary pollution on the surrounding environment is avoided, and harm to the health of a worker is reduced.
Description
Technical field
The utility model relates to a kind of residue extraction mechanism of boiler slag-cooling machine, especially a kind of deslagging dust arrester of boiler slag-cooling machine.
Background technology
Cold slag machine is a kind of continuous discharging slag equipment of boiler of power plant, and it reclaims heat of slags and has reduced deslagging temperature and reduced the deslagging heat loss and improve boiler thermal output in tapping process.Cold slag machine in the continuous discharging slag process because of have coal-fired in burner hearth repeatedly circulating combustion formed a large amount of thin ashes, thin ash is mixed in the slag and discharges by slag notch through cold slag machine recovery heat treatment, the thin ash of heat expanded and forms airborne dust when slag was discharged, because the close secondary pollution source that has formed surrounding environment of slag notch seal closure bad sealing, also waste the input of manpower and materials, also jeopardized the healthy of worker simultaneously.
The utility model content
The purpose of this utility model provides a kind of airborne dust that produces can in time remove deslagging time the and the deslagging dust arrester of avoiding surrounding environment is caused the boiler slag-cooling machine of secondary pollution.
In order to finish above-mentioned purpose, the technical solution adopted in the utility model is:
A kind of deslagging dust arrester of boiler slag-cooling machine, comprise the cold slag machine that links to each other with boiler, the cinder notch of going into of cold slag machine links to each other with the slag-drip opening of boiler, and cold slag machine is provided with slag notch, also comprise the suction port that is arranged on the slag notch top, suction port is provided with pipeline and communicates with the dust mouth.
Described dust mouth links to each other with the flue of boiler.
Described pipeline is provided with valve with the dust mouth and links to each other.
The beneficial effects of the utility model are: owing to be provided with suction port, pipeline and the dust mouth that communicates with boiler flue at cold slag machine slag notch, the thin grey airborne dust that produces when making deslagging is discharged from boiler flue, avoided surrounding environment is caused secondary pollution problem, alleviated the harm to worker health.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure, 1, boiler, 2, cold slag machine, 3, go into cinder notch, 4, slag-drip opening, 5, slag notch, 6, suction port, 7, pipeline, 8, the dust mouth, 9, flue, 10, valve.
The specific embodiment
The utility model is a kind of deslagging dust arrester of boiler slag-cooling machine, owing to be provided with suction port, pipeline and the dust mouth that communicates with boiler flue at cold slag machine slag notch, the thin grey airborne dust that produces when making deslagging is discharged from boiler flue, avoided surrounding environment is caused secondary pollution problem, alleviated the harm to worker health.
Below in conjunction with accompanying drawing the utility model is described further.
Specific embodiment, as shown in Figure 1, a kind of deslagging dust arrester of boiler slag-cooling machine, comprise the cold slag machine 2 that links to each other with boiler 1, the cinder notch 3 of going into of cold slag machine 2 links to each other with the slag-drip opening 4 of boiler 1, and cold slag machine 2 is provided with slag notch 5, also comprise the suction port 6 that is arranged on slag notch 5 tops, suction port 6 is provided with pipeline 7 and communicates with dust mouth 8, dust mouth 8 is linked to each other with the flue 9 of boiler 1, and be provided with valve 10 link to each other between pipeline 7 and dust mouth 8.When boiler 1 deslagging, slag-drip opening 4 is gone into cinder notch 3 with what waste residue entered cold slag machine 2, waste residue is discharged from slag notch 5 after cold slag machine 2 coolings, owing to be provided with suction port 6 above slag notch 5, suction port 6 links to each other with dust mouth 8 by pipeline 7, and dust mouth 8 communicates with the flue 9 of boiler 1 again, be negative pressure in the flue 9, so the thin grey airborne dust of discharging from slag notch 5 is discharged into flue 9 discharges from pipeline 7, thereby has avoided surrounding environment is caused secondary pollution problem, has alleviated the harm to worker health.
Claims (3)
1. the deslagging dust arrester of a boiler slag-cooling machine, comprise the cold slag machine (2) that links to each other with boiler (1), the cinder notch (3) of going into of cold slag machine (2) links to each other with the slag-drip opening (4) of boiler (1), cold slag machine (2) is provided with slag notch (5), it is characterized in that: also comprise the suction port (6) that is arranged on slag notch (5) top, suction port (6) is provided with pipeline (7) and communicates with dust mouth (8).
2. the deslagging dust arrester of a kind of boiler slag-cooling machine according to claim 1, it is characterized in that: described dust mouth (8) link to each other with the flue (9) of boiler (1).
