Domain.
Background technology
Economizer is the important equipment in large coal-fired boiler, and economizer is installed on boiler back end ductwork lower part for recycling
The waste heat discharged fume, economizer absorb the heat of high-temperature flue gas, reduce the exhaust gas temperature of flue gas, play and save the energy, carry
Efficient effect.It finds in actual use, the economizer hopper flow field of large coal-fired boiler is due to reasons in structure, by flue gas
High velocity influences, and has from the ash content under ash bucket overhead stream and is greatly blown away by high velocity smoke, can not fall into lower part ash bucket, make
It is bad into large coal-fired boiler ash bucket dedusting effect.Air matter is greatly affected in air since the ash content in flue gas descends slowly and lightly
Amount, causes environmental pollution, it would be highly desirable to solve.
Utility model content
The utility model is related to a kind of boiler economizer ash bucket collection apparatus for ash, this collection apparatus for ash can be effectively improved large size

Boiler ash bucket dedusting effect improves boiler ash bucket ash disposal ratio.
Solving the technical solution of above-mentioned technical problem is：
A kind of boiler economizer ash bucket collection apparatus for ash, it includes dust collecting box and ash conveying pipe, and dust collecting box is rectangular box,
The upper face of dust collecting box is evenly equipped with the grey hole of multiple collection, collects grey hole and is connected with the babinet chamber of dust collecting box, ash conveying pipe is connected to
The box back of dust collecting box, dust collecting box are placed on the upward sloping portion above boiler economizer ash bucket, the length side of dust collecting box
To the upward inclined direction along boiler economizer ash bucket, dust collecting box rear end connection ash conveying pipe, the upper end of ash conveying pipe and collection
The babinet chamber of cinder box is connected, and the lower end of ash conveying pipe is connected with boiler economizer ash bucket.
Above-mentioned boiler economizer ash bucket collection apparatus for ash, the dust collecting box and ash conveying pipe are one or more, multiple collection ashes
Case is placed in parallel the upward sloping portion above boiler economizer ash bucket, and multiple ash conveying pipes are connected respectively with multiple dust collecting boxes
It connects.
Above-mentioned boiler economizer ash bucket collection apparatus for ash, it also has deflector, and deflector is rectangle steel plate, and deflector is located at
The back upper place of dust collecting box, the length direction of deflector is parallel with the length direction of dust collecting box, deflector and boiler economizer ash bucket
Side wall is vertically fixed.
Above-mentioned boiler economizer ash bucket collection apparatus for ash, the deflector is one or more, multiple deflector parallel verticals
The top of boiler economizer ash bucket is fixed on, deflector is located at the back side top of dust collecting box.
The beneficial effects of the utility model are：
The dust collecting box of the utility model is placed at the climbing of economizer hopper, and the upper plane of dust collecting box is evenly equipped with multiple collection
Grey hole can be fallen into dust collecting box from the grey hole of collection by the ash content of plane on boiler economizer ash bucket and be collected, prevent ash content
It is lost in；Deflector is perpendicularly fixed at the side wall of dust collecting box, and the length direction of deflector is along boiler economizer ash bucket to updip
Tilted direction, deflector can optimize the air velocity distribution above ash bucket, reduce flue gas flow rate at dust collecting box, improve the grey effect of collection.
The utility model is simple in structure, easy to use, collection ash works well, and can be effectively improved large coal-fired boiler and save coal
Ash bucket top ash content is effectively collected in flow field at device ash bucket, prevents the secondary loss of top ash content.The utility model significantly adds
The strong dedusting effect of boiler economizer ash bucket, improves boiler economizer ash bucket except ash ratio, being worth in industry promoting makes
With.
