Abstract
The utility model discloses a dry-slag removing device for a power plant to solve the technical problem that elbows in the existing negative pressure ash removing pipeline are easy to wear to cause leak. The dry-residue removing device comprises a boiler (1), a steel band machine (2) used for conveying slags, an intermediate slag warehouse (3), a negative pressure conveying pipeline (4) used for conveying the slags, and a slag warehouse (5), wherein a lateral wall of an elbow of the negative pressure conveying pipeline (4) is provided with a back arc plate (5), the back arc plate (5) is fixedly connected to the negative pressure conveying pipeline (4) through a flange (6), and an internal surface of the back arc plate (5) is provided with a wear-resisting composite layer. By adopting the dry-slag removing device of the utility model, the back arc plates of the elbows can be regularly replaced according to degree of wear of the elbows, thereby reducing equipment maintenance costs as well as overhauling and maintenance workload.
Description
Technical field
The utility model relates to a kind of deslagging device, particularly a kind of pnenmatic slag handling device that is applied to the thermal power plant.
Background technology
The slag in thermal power plant is with the operation that removes the gred of the dried slag dedusting of negative pressure of ash disposal system, because of a plurality of elbows are usually arranged in the dedusting of negative pressure pipeline, slag is under the effect of negative pressure, impact these elbow interior wall with certain impulsive force, particularly elbow porch and medium impact site are because leakage phenomenon takes place through regular meeting in serious wear, cause dried slag induction system to be leaked out, influence unit load; In addition, because elbow weight is heavier, when the elbow of breakage is changed, exist workload big, the problem that working strength is high.
Summary of the invention
The utility model provide a kind of power plant the pnenmatic slag handling device solves the ducted elbow of existing dedusting of negative pressure be worn easily and the technical problem revealed.
The utility model overcomes the above problems by following scheme:
A kind of pnenmatic slag handling device of power plant, the negative pressure transportation pipeline and the slag storehouse that comprise boiler, the steel band machine of carrying slag, middle slag storehouse, conveying slag, be provided with back of the body arc plate at the lateral wall place of the elbow of described negative pressure transportation pipeline, this back of the body arc plate is to be fixed together by flange and negative pressure transportation pipeline.
The inner surface of described back of the body arc plate is provided with wear-resistant composite bed.
The utility model has reduced equipment maintenance cost and repair and maintenance workload according to elbow degree of wear periodic replacement elbow back arc plate, improves the equipment operational reliability, the equipment that reaches operation steady in a long-term.
Description of drawings
Fig. 1 is a structural representation of the present utility model
The specific embodiment
A kind of pnenmatic slag handling device of power plant, the negative pressure transportation pipeline 4 and the slag storehouse 5 that comprise boiler 1, the steel band machine 2 of carrying slag, middle slag storehouse 3, conveying slag, be provided with back of the body arc plate 5 at the lateral wall place of the elbow of described negative pressure transportation pipeline 4, this back of the body arc plate 5 is to be fixed together by flange 6 and negative pressure transportation pipeline 4.The inner surface of described back of the body arc plate 5 is provided with wear-resistant composite bed.
The utility model at the wear-resisting back of the body arc of this Position Design plate, requires back of the body arc plate wearing layer and inner-walls of duct to seamlessly transit according to elbow abrading section and medium and tube wall projected angle of impact, reduces the media flow resistance, installs and adopts flange to connect, and is convenient to change and installs.After adopting the elbow back plate structure, only change elbow back arc plate according to the elbow abrasion condition, improve operation hours and standby time, little to the complete equipment influence, device security stable operation is improved.
Claims (2)
1. the pnenmatic slag handling device of a power plant, the negative pressure transportation pipeline (4) and slag storehouse (5) that comprise boiler (1), the steel band machine (2) of carrying slag, middle slag storehouse (3), conveying slag, it is characterized in that, be provided with back of the body arc plate (5) at the lateral wall place of the elbow of described negative pressure transportation pipeline (4), this back of the body arc plate (5) is to be fixed together by flange (6) and negative pressure transportation pipeline (4).
