Abstract
The invention discloses an abrasion resistant device of a boiler water wall tube, and belongs to the field of boiler water wall tube protection. The abrasion resistant device of the boiler water wall tube is composed of a water wall tube and an abrasion resistant plastic material laid on the water wall tube. As the technical characteristics of the invention, the abrasion resistant plastic material laid on the water wall tube protrudes toward the opposite direction of the water wall tube; the protruding part of the abrasion-resistant plastic material is externally provided with a fixed cover; the water wall tube is externally provided with a seal box. According to the invention, through the technical improvement above, abrasion resistant device has the following beneficial effects that the water wall tube is externally laid with the abrasion resistant plastic material under the condition of guaranteeing that the original configuration of a screen-type overheater is not changed, and the erosion and abrasion is relieved and reduced, so that the boiler abrasion is reduced; the boiler stopping and maintaining times is reduced; the production is convenient; the production efficiency is improved.
Description
Technical field
The invention belongs to boiler water wall protection of pipe field, is a kind of shoe of boiler water-wall tube specifically.
Background technology
In production, because the boiler operatiopn time is long, the wearing and tearing of water screen tube various degrees.Due to the abrasion mechanism of CFBB, generally can be divided into adhesive wear, abrasive wear, corrosive wear, contact fatigue wearing and tearing, erosive wear and fretting wear etc., wherein the wearing and tearing of CFBB be take erosive wear especially as main.So-called erosive wear refers to that fluid or solid particle impact the wearing and tearing that caused or claim impact wear material surface with certain speed and angle.Erosive wear has two kinds of fundamental types, a kind of erosive wear that is called, and another kind is brinelling, and the microscopic appearance of the loss process on the erosion surface of these two kinds of wearing and tearing is incomplete same.Erosive wear is that Particle Phase is less to the surface of solids angle of shock, even approaches parallel.Particle is inserted into by impacted object it perpendicular to minute speed of the surface of solids, and the tangent minute speed of particle and the surface of solids makes it along body surface, slide, and within two minutes, the synthetic effect of speed plays a kind of planing effect.If the object being impacted is unable to undergo this effect, be cut a fritter, so, through effect in a large number, repeatedly, the surface of solids will produce wearing and tearing.Brinelling refers to that Particle Phase is larger for surface of solids angle of attack, or when vertical, with certain movement velocity, clashing into the surface of solids makes it produce small plastic deformation or micro-flaw, under long-term, a large amount of particles clashes into repeatedly, make gradually plastic deformation layer's full wafer come off and the wearing and tearing that form.
Summary of the invention
In order to address the above problem, the present invention aims to provide a kind of in the situation that guaranteeing not change the original layout of pendant superheater, adopts the outside shoe that corrosive-proof plastic material solves the boiler water-wall tube that alleviates, reduces erosive wear that lays.
In order to achieve the above object, the present invention has adopted following technical scheme: the shoe of boiler water-wall tube, by water screen tube with lay corrosive-proof plastic material thereon and form, as technical characterictic of the present invention, the corrosive-proof plastic material laying on water screen tube protrudes to water-cooled tube wall rightabout, and the projection outside of corrosive-proof plastic material is provided with fixed cover; Water screen tube outside is provided with seal box.
As a further improvement on the present invention, all water screen tubes that corrosive-proof plastic material is laid in seal box are outside.
As a further improvement on the present invention, the gap of seal box and water screen tube is filled with alumina silicate fiber felt.
The present invention is through above-mentioned technological improvement, reached following beneficial effect: by the situation that guaranteeing not change the original layout of pendant superheater, adopt water screen tube outside to lay corrosive-proof plastic material and alleviate, reduce erosive wear, thereby reduce the wearing and tearing of boiler boiler, reduce the number of times that boiler stops production and keeps in repair, convenient production, has improved production efficiency.
Accompanying drawing explanation
Fig. 1 is the shoe side view of boiler water-wall tube of the present invention;
Fig. 2 is the shoe top view of boiler water-wall tube of the present invention.
The specific embodiment
The shoe of boiler water-wall tube, by water screen tube 1 with lay corrosive-proof plastic material 2 thereon and form, the corrosive-proof plastic material laying on described water screen tube 1 protrudes to water-cooled tube wall 1 rightabout, and the projection outside of corrosive-proof plastic material 2 is provided with fixed cover 3; Water screen tube 1 outside is provided with seal box 4.
Described corrosive-proof plastic material 2 all water screen tubes 1 outside in seal box 4 that is laid in.
Described seal box 4 is filled with alumina silicate fiber felt 5 with the gap of water screen tube 1.
In Fig. 1 and Fig. 2, the position of pendant superheater 6 does not change.
Because outer the laid corrosive-proof plastic material of water screen tube 1 is protruding, changed the falling direction of the thin ash particle of the adherent vertical drop of upper furnace, thereby reduced wearing and tearing.
