Description
Technical field
The invention belongs to cyclone separator field, especially a kind of Abrasion Resistance Liner of Cyclone skin patching method.
Background method
Petrochemical industry heavy oil catalytically cracking equipment is the main device of oil refining, and the reacting gas containing a large amount of catalyst enters high temperature rotation
Wind separator, cyclone separator is applied very extensive, by being catalyzed after centrifugation as the separation equipment of solid and admixture of gas
Agent is reusable, and oil gas or flue gas then enter next operation.Due to contained urging in the gas of entrance cyclone separator
Agent hardness is higher, and flow velocity is quickly, and the abrasion to metal wall is very big, so being required in high temperature cyclone separator installing tortoise
Metal shell protected by first net high abrasion lining.
At present, the high abrasion lining preparation method of cyclone separator is that first on metal wall, throat thickness is 20mm to 25mm
Mesh sheet (i.e. hexsteel) in tortoise plastron shape, then clogging in the mesh of this mesh sheet by the abrasive material such as corundum or bauxite clinker is main one-tenth
The high abrasion lining material of part.Conventional high abrasion lining material bonding agent mainly includes aluminate cement and phosphate two kinds.By
In being the particle of 3mm-5mm containing maximum gauge, so when making lining, needs pressure repeatedly smears pressure surface, so that surface is put down
Whole, reducing high abrasion backing layer affects the deterioration of separative efficiency.After high abrasion lining uses a period of time, the shortest 1
Within Nian, surface blistering, peeling phenomenon often occur, surface becomes uneven, affects separative efficiency, and serious meeting causes
Catalyst leakage, reduces economic benefit, needs to carry out repair maintenance.Due to high abrasion lining dismounting, reform, repair all ten
Point difficulty, in irregular shape, the narrow space of cyclone separator, various operation are the most limited.And hexsteel dismounting difficulty is big,
Again the high abrasion lining quality of ramming is difficult to guarantee, long construction period, and in most cases the engineering time does not allows.Local is high
High-abrasive material is repaired, and owing to repair layer thickness is little, generally 1mm-3mm, cohesive force is poor, thus repair efficiency is bad.
Summary of the invention
It is an object of the invention to overcome the most methodical weak point, it is provided that a kind of Abrasion Resistance Liner of Cyclone skin patching side
Method, this method speed of application is fast, cohesive force is strong, wearability is good, and service life is long, and effect is notable.
The present invention solves its method problem and takes following methods scheme to realize:
A kind of Abrasion Resistance Liner of Cyclone skin patching method, the steps include:
(1) clear up old wear resistance lining: first that the removing surface of old wear resistance lining is clean, the catalyst, blistering and the bonding that adhere to
Lining material perching knife or hammer drill, hairbrush etc. loosely are removed clean, are then fully soaked on surface with compressed air or clear water,
Reach surface moisture, anhydrous trickling；
(2) full-filling wear-resistant paint: use and manually scratch mode, uses float or little barreled high temperature abrasion material during artificial blade coating,
It is put on cleaver or pressure and firmly smears wear resistance lining surface, or use hairbrush to brush wear resistance lining table after dipping in full high temperature abrasion material
Face；
(3) surface is levelling: carry out carrying out levelling to wear-resistant paint surface with hairbrush；
(4) the later stage processes: should prevent from making moist after high temperature abrasion material construction, after natural draft drying, slowly heats up and dries
Stove is processed, or directly comes into operation.
And, the step (2) artificial blade coating described in full-filling wear-resistant paint replaces with mechanically spraying, i.e. uses spray gun by high-temperature wearable
Coating is sprayed onto wear resistance lining surface, and the high temperature abrasion material at mesh sheet need to fill up.
And, step (2) high temperature abrasion material construction in layer described in full-filling wear-resistant paint, every layer thickness is 1-2mm, last layer
High temperature abrasion material treats underlying surfaces row construction the most again.
And, described high wear resistance coatings include corundum fine powder, carbide fine powder, submicron order and nano level superfine composite micro-powder,
Bonding agent and additive, use inorganic and organic composite bonding agent to be combined into.
And, constituent and the weight fraction of described high wear resistance coatings are respectively as follows:
Corundum fine powder is 50-90%；
Composite micro-powder is 1-15%；
Bonding agent is 5-15%；
Additive is 0.1-2%.
And, described high wear resistance coatings adds carbide fine powder, the weight fraction of carbide fine powder is less than 20%.
And, described corundum fine powder particle diameter be how many scopes be 0.5-0.074mm, carbide fine powder particle diameter is that how many scopes are
0.15-0.074mm。
And, described composite micro-powder composition and weight ratio are SiO2:Al2O3:SiC=1:1:1。
And, described bonding agent is SiO2·Al2O3·0.1Na2O。
And, described additive is by phosphate polymer, silicate polymer, lignosulfonates, melamine class, carboxylic acids etc.
One or more compositions therein.
Advantages of the present invention and good effect be:
1, the present invention removes catalyst, blistering and the bonding lining material loosely that high abrasion liner surface adheres to, then to surface
Carry out clear water wetting, then use the method for manual blade coating or mechanically spraying to carry out skin patching, be dried after having repaired, can be slow
Speed intensification baker or directly come into operation.
2, high wear resistance coatings refractory temperature of the present invention is high, wearability is strong, caking property is strong, and combined binder has the strongest
Cohesive force, add compound additive, it is possible to use little moisture makes bonding agent dispersed, have the strongest viscous after drying
Knot power, even the steel relatively smooth with surface also have stronger cohesive force, can make the thinnest coating, and wear-resistant paint
Particle the least, the thinnest thin layer can be painted, and this high wear resistance coatings wall built-up is strong, it is simple to facade and end face construction, resistance to
Mill coating belongs to visco-plasticity system, and viscosity is relatively big, is difficult to tenesmus, beneficially facade and end face construction, and construction method is various,
