Description
Technical Field
The utility model relates to a power plant's slag storehouse raise dust collecting system.
Background
A thermal power plant is a plant that produces electric energy using coal, oil, natural gas, and the like as fuel. The slag particles generated after the coal is fired in the boiler are thicker, and are generally cooled by a slag cooler and then are input into a slag warehouse nearby. The slag (containing a large amount of fly ash) collected in the slag warehouse is transported away by a bulk machine slag loading vehicle at the bottom of the slag warehouse.
When the slag is discharged from the slag warehouse, a large amount of dust is scattered, and the surrounding environment is easily influenced. The following reasons exist for flying of slag-discharging flying dust in the slag warehouse: when the slag ash falls, the slag ash is influenced by the surrounding exposed environment, and the flying dust is scattered due to the blowing of the transverse wind; due to the action of gravity, when slag ash descends to the bottom of the slag car, an impact effect is generated, and flying dust is generated by impact; the scattered flying dust forms random movement and spreads to the periphery, and the like. Therefore, a technique for collecting the dust generated during the slag discharge is needed to protect the environment.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome the above-mentioned not enough that exists among the prior art, and provide a reasonable in structural design's power plant's slag storehouse raise dust collecting system, can collect the raise dust when unloading the sediment.
The utility model provides a technical scheme that above-mentioned problem adopted is: the utility model provides a power plant's slag storehouse raise dust collecting system which characterized in that: comprises an isolation cloth, a screw, a first filter screen, a slag dropping pipe, an air suction hood, an exhaust pipe, a second filter screen and an exhaust fan; the isolation cloth is fixed around the bottom of the air suction cover by screws to surround the periphery of the bottom of the air suction cover; the first filter screen is arranged at the bottom of the air suction cover; the slag dropping pipe is fixedly arranged in the air suction hood, the inlet of the slag dropping pipe extends out of the air suction hood, and the outlet of the slag dropping pipe extends out of the first filter screen; the exhaust pipe is connected with the air suction cover; exhaust fan and No. two filter screens are all installed on the exhaust pipe, and No. two filter screens are located the place ahead of exhaust fan.
The air suction cover of the utility model is horn-shaped and is made of stainless steel.
The air suction cover of the utility model is made of stainless steel.
The isolation cloth is made of flame-retardant rubber cloth.
The slag falling pipe of the utility model is in a shape of Chinese character 'ren', and the part of the slag falling pipe in the air suction cover is branched to form two outlets.
The exhaust fan adopt an axial flow exhaust fan.
Compared with the prior art, the utility model, have following advantage and effect: can collect dust during slag unloading, and protect the environment. Utilize isolation cloth to carry out large tracts of land sealing treatment around the air-suction hood for raise dust and all ring edge borders are kept apart when unloading the sediment, filter the raise dust through the filter screen, carry out the processing of airing exhaust to the air in the air-suction hood through the exhaust fan.

Detailed Description
The present invention will be described in further detail by way of examples with reference to the accompanying drawings, which are illustrative of the present invention and are not intended to limit the present invention.
The embodiment of the utility model provides a including isolation cloth 2, screw 3, filter screen 4, the sediment pipe 5 that falls, the cover 6 that induced drafts, exhaust pipe 7, no. two filter screens 8 and exhaust fan 9.
The air suction cover 6 is in a horn shape with a small upper part and a big lower part and is made of stainless steel.
The isolation cloth 2 is fixed around the bottom of the air suction cover 6 by screws 3, and surrounds the periphery of the bottom of the air suction cover 6. The isolation cloth 2 is made of flame-retardant rubber cloth.
The first filter screen 4 is arranged at the bottom of the air suction hood 6.
The slag dropping pipe 5 is fixedly arranged in the air suction hood 6, the inlet of the slag dropping pipe 5 extends out of the air suction hood 6, and the outlet of the slag dropping pipe 5 extends out of the first filter screen 4. The slag falling pipe 5 is in a herringbone shape, and the part positioned in the air suction cover 6 is branched to form two outlets and rapidly fall slag.
The exhaust pipe 7 is connected with the air suction hood 6. Exhaust fan 9 and No. two filter screens 8 all install on exhaust pipe 7, and No. two filter screens 8 are located the place ahead of exhaust fan 9, and exhaust fan 9 adopts the axial compressor exhaust fan. The flying dust and air quality of the flying dust of the slag unloading system can not meet the requirement of directly discharging the flying dust to the outside, so the flying dust can not be directly discharged to the outside, and a second filter screen 8 is required to be arranged in front of the exhaust fan 7.
When the slag discharging device is used, an inlet of the slag discharging pipe 5 is connected with an outlet of the slag storage 11, the bottom of the air suction cover 6 is aligned to a hopper of the slag car 1, and the periphery of the top of the hopper is surrounded by the isolation cloth 2. An outlet electromagnetic valve 10 of the slag storage 11 is opened, a corresponding exhaust fan 9 is opened, slag ash in the slag storage 11 falls into the slag car 1 through a slag falling pipe 5, the dust flying of the slag ash is isolated from the surrounding environment through an isolation cloth 2, negative pressure is generated in an air suction cover 6, most of the flying dust is filtered by a first filter screen 4 and then is exhausted through a second filter screen 8, and the electromagnetic valve 10 is closed after the slag car 1 is filled with the slag. Under the condition that the system runs for a long time, the non-combustible isolation cloth 3 can be detached and cleaned through the screw 2, and the first filter screen 4, the second filter screen 8, the exhaust fan 9 and the like can be cleaned, maintained and the like.
