Description

Wear-resistant plate for boiler water-cooled wall pipeline

Technical Field

The invention belongs to the technical field of wear plates, and particularly relates to a wear plate for a boiler water wall pipeline.

Background

The water cooling wall is the main heated part of the boiler and consists of a plurality of rows of steel pipes which are distributed around the boiler furnace. The interior of the boiler is flowing water or steam, and the outside receives heat of flame of a boiler hearth. Mainly absorbs the radiant heat of high-temperature combustion products in the hearth, and the working medium moves upwards in the hearth and is heated and evaporated.

The wear-proof plate, also called wear-proof cover, wear-proof tile, wear-proof protection tile, wear-proof cover plate, boiler climbing pipe, wear-proof pressing plate, etc., is a common fitting for heating surface pipes of power station boiler, and is matched with the clamping ring for use.

The wear-resistant plate is mainly used on windward sides of heating surface pipes such as a superheater, a reheater, an economizer, a water wall pipeline and the like of a boiler, and also can be used (the consumption is small) for an induced draft fan, and mainly aims to protect the windward sides of the boiler pipelines, reduce abrasion caused by erosion of the pipelines by smoke in the boiler and prolong the service life of the heating surface pipes. The industry generally refers to "wear shoes" and "wear plates" in general. The wear-resisting plate is a special part of a boiler, is commonly used for power station boilers, is used for small boilers, and is used for some coal chemical industry.

The existing anti-abrasion plate is fixed on the water wall pipeline and used for protecting the windward side of the water wall pipeline, so that smoke in the boiler is blown on the anti-abrasion plate, direct blowing of the water wall pipeline is reduced, the surface of the existing boiler anti-abrasion plate is smooth, friction force is large when the existing boiler anti-abrasion plate contacts with the smoke, the anti-abrasion plate is also easy to abrade, and meanwhile the smoke is blown on the surface of the traditional anti-abrasion plate to generate noise, so that noise is generated inside the boiler in production, and worker operation is affected.

Disclosure of Invention

The invention aims to: the invention aims to provide an anti-wear plate for a boiler water-cooled wall pipeline, which aims to solve the technical problems that the existing anti-wear plate is not wear-resistant and generates noise due to contact friction with smoke.

The utility model provides a boiler water-cooled wall is abrasionproof board for pipeline, includes the abrasionproof board, the abrasionproof inboard is equipped with the water-cooled wall pipeline, and the abrasionproof board protects its characterized in that to the windward side of water-cooled wall pipeline: the anti-abrasion plate is internally provided with a group of evenly densely distributed ball seats, balls are arranged in the ball seats, the balls can rotate in the ball seats, when smoke is blown to the balls on the anti-abrasion plate, the balls rotate on the ball seats, the balls always rotate in the ball seats, the bottom of the ball seats is provided with an air inlet pipe, part of smoke enters the ball seats through gaps between the ball seats and the balls, the anti-abrasion plate is internally provided with a silencing chamber, the air inlet pipe is communicated with the silencing chamber, silencing cotton is arranged in the silencing chamber, two sides of the anti-abrasion plate are provided with fixing plates, an exhaust pipe is arranged in the fixing plates, the exhaust pipe is communicated with the silencing chamber, the smoke in the ball seats enters the silencing chamber through the air inlet pipe, and noise generated by smoke friction enters the exhaust pipe after being absorbed by the silencing cotton and is discharged through the exhaust pipe.

Furthermore, the back of the wear-resistant plate is provided with a clamping ring, a water wall pipeline is arranged between the wear-resistant plate and the clamping ring, and the water wall pipeline is fixed on the inner side of the wear-resistant plate through the clamping ring.

Further, the snap ring both sides are equipped with the cardboard, be equipped with the perforation on the cardboard, be equipped with the bolt on the fixed plate, the bolt passes the perforation, be equipped with the nut on the bolt, pass the perforation through the bolt to through the threaded connection of nut and bolt, make fixed plate and cardboard fixed.

Compared with the prior art, the invention has the following advantages:

through ball seat and ball that evenly distributes on the abrasionproof board for the flue gas that blows in the boiler blows the ball and rolls on the ball seat, makes originally the sliding friction that the flue gas blown to on the abrasionproof board become with the rolling friction of ball, and rolling friction is far less than sliding friction, so the wearing and tearing of flue gas to the abrasionproof board also reduce greatly, has prolonged the life of abrasionproof board.

Through the ball seat and the ball design on the wear prevention plate, the surface area of the wear prevention plate is increased, and the smoke is evenly dispersed by the ball, so that the impact force of the smoke is evenly dispersed, the impact force is slowed down, and the wear of the wear prevention plate is reduced.

The ball is rotated in the ball seat to the flue gas blowing, and the ball is inlayed all the time in the ball seat and is not broken away from the ball seat for part and the friction of abrasionproof board produce the flue gas of noise by pivoted ball winding get into in the ball seat through the gap between ball seat and the ball, in the rethread intake pipe gets into the silence room, make the noise in the flue gas absorbed by the amortization cotton in the silence room, reach the function of making an uproar to the boiler inside.

The technical problems that an existing wear-resistant plate is not wear-resistant and noise is generated due to contact friction with smoke are solved.
