How to prevent the water wall of the circulating fluidized bed boiler furnace from wearing and bursting is the key of the device which can safely and stably operate for a long time. At present, in a circulating fluidized bed boiler z, a water wall is a common component, namely a water wall pipe, which is called a water wall and is also called a riser. The boiler heating surface is generally vertically paved on the inner wall surface of a furnace wall and is mainly used for absorbing radiant heat emitted by flame and high-temperature flue gas in the furnace. Is the main type of the evaporation heating surface of various modern boilers and is also the basic component in a boiler water circulation loop. The anti-abrasion technology of the anti-abrasion plate is that the low-carbon high-chromium high-nickel alloy plates are transversely and longitudinally arranged to prevent abrasion, so that the flow speed and the flow direction of wall-attached particles are damaged, and a good anti-abrasion effect is achieved.

However, most of the wear-resistant plates at the present stage are flat plates, and even if the fan is additionally arranged above the wear-resistant plates, the light and thin thickness of the wear-resistant plates and the pressure borne by the wear-resistant plates in the vertical direction are still unbalanced. However, the applicant believes that the wear-resistant plate in the prior art still has the problems of single function and poor mechanical property, and particularly, the service life of the wear-resistant plate at the junction is low and the wear degree is large.

Detailed Description

The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are described herein for the purpose of illustration and explanation and not limitation.

Example 1

An anti-abrasion guide plate with wave grooves is designed, referring to fig. 1 to 6, and comprises guide plate unit blocks 1 which are mutually lapped, wherein semicircular through grooves 3 matched with fin pipes of a water-cooled wall are formed in the guide plate unit blocks 1, and at least two layers of semicircular annular bulges or grooves 2 are concentrically arranged on the guide plate unit blocks and the semicircular through grooves 3. In the design of this embodiment, the massive plane has been avoided, has improved the mechanical properties on equipment surface through the design of recess 2 and protruding. The overall hardness is higher. And simultaneously plays a role in guiding hot air mass. When the material flow falls down, the speed is reduced when the material flow passes through the groove 2, and because the speed is reduced, the impact on the root is smaller than that in a high-speed state, so that the protection effect is realized.

The bulges or the grooves 2 form an insertion channel so as to insert insertion blocks 5 above the guide plate unit blocks 1, the insertion blocks 5 are perpendicular to the horizontal plane and the wall surface, and the distance between the insertion blocks 5 is 30-80 cm. The design can divide the hot air flow left from the upper part into zones to form air mass flowing like a ball at the junction between the guide plate and the wall surface, then the hot air flow at the rear part flows like a ball below smoothly passing the air mass above the air mass, in the process, the air mass cleans the guide plate, and the air flow flowing like the lower part at the rear part flows downwards in a relatively gentle flow direction.

Oblique guide strips 8 are arranged on two sides of the inserting block 5. Further facilitating the formation of air pockets.

The height of the insert block 5 is less than 20 cm. Too short is not easy to form air mass, too long self weight causes burden to the deflector unit block 1.

The inserting block 5 comprises a stop block at the top and an inserting block at the bottom, the inserting block is matched with the shape and position sizes of the bulges or the grooves 2, and the inserting block is matched with the stop block through a polygonal fixing column and a matched polygonal column hole. In the installation process, the installation angle is inserted at different angles according to different installation angles, the debugging is carried out in advance, and then the installation at the later stage is rapid.

The cross section of the protrusion or the groove 2 is square or round.

Example 2

In this embodiment, the cross-sectional shape of the protrusion or groove 2 is replaced by 3/4 spherical cap shape. An inclined support 6 is arranged between the lower part of the guide plate unit block 1 and a wall body, and the top of the inclined support 6 is a spherical crown matched with the cross section of the bald or groove 2 and provided with a spherical surface/shape and position size of the groove 2. The design can further realize clamping and bottom support.
