Description
Technical field
The utility model belongs to thermal power plant coal chute installation fitting applied technical field, and in particular to one kind is applied to
The ceramic elbow knapsack of defeated pulverized coal channel, filled suitable for the defeated pulverized coal channel of generating of power plant 600MW units or 1000MW units
With use, its wear-resisting, high temperature resistant, impact resistance, service life are long and are easily installed and demolition and maintenance.
Background technology
Thermal power plant abbreviation thermal power plant, it is to utilize combustible（Such as coal）As the factory of fuel production electric energy, it
The basic process of production is：Fuel heats water generation steam in burning, the chemical energy of fuel is transformed into heat energy, vapour pressure is pushed
Dynamic steam turbine rotation, heat energy are converted into mechanical energy, and then steam turbine drives generator rotation, and mechanical energy is transformed into electric energy.
Thermal power plant pulverized coal conveying generally use air-flow conveying solid substance coal dust, its conveyance conduit generally include straight tube and changed
Becoming the bend pipe composition of the different angle of the pulverized coal flow direction of motion, existing conveyance conduit generally use seamless steel pipe is made, its is wear-resisting,
Heat-resisting, corrosion resistance and mechanical strength, shock resistance are bad, are mainly shown as that pulverized coal flow changes direction in bend pipe and led
Cause to the strong shock of elbow sidewall, not only make bend pipe wall serious wear, also straight tube is caused to wear, while seriously affect pipeline
The safe operation of system, in addition, must shut down replacing after bend pipe or straight tube breakage, maintenance cost is high, has a strong impact on thermal power generation
The normal operation of factory, the problem of causing low operating efficiency, increase production cost, and this is current urgently to be resolved hurrily.
Therefore, a kind of ceramic elbow knapsack applied to defeated pulverized coal channel is provided based on above mentioned problem, the utility model.
Utility model content
Purpose of utility model：The purpose of this utility model is to provide a kind of ceramic elbow applied to defeated pulverized coal channel and carried on the back
Bag, its design structure rationally and are easy to assembling and demolition and maintenance, and ceramic lining plate body is wear-resisting, heat-resisting, corrosion resistance and machinery
Intensity, shock resistance are forced with long lifespan, high without normal maintenance down operating efficiency, while solve the inconvenience dimension of traditional structure
The phenomenon of shield, can be according to needing to change the ceramic lining plate for impacting, wearing larger elbow position, without being carried out more to overall
Change, reduce financial cost and save maintenance time.
Technical scheme：The utility model provides a kind of ceramic elbow knapsack applied to defeated pulverized coal channel, including elbow, and
Be arranged on elbow and with elbow structure identical enhancement layer, and several ceramic liners being uniformly arranged in elbow upper inside wall
Plate, wherein, the overall structure thickness of elbow, enhancement layer and ceramic lining plate is 25mm, and the thickness of elbow is 6mm, ceramic lining plate
Thickness is 12mm；The ceramic lining plate is uniformly arranged in elbow interior wall using adhesive dress patch or welding manner.
The technical program, the ceramic elbow knapsack applied to defeated pulverized coal channel, in addition to be arranged in enhancement layer
Between auxiliary connecting pole, wherein, aid in a diameter of 12mm, the length 100mm of connecting pole.
The technical program, the middle ceramic lining plate in elbow interior wall is arranged to " n " type structure, and " n "
Type structure both sides are symmetrically arranged with fixed edge.
Compared with prior art, a kind of ceramic elbow knapsack applied to defeated pulverized coal channel of the present utility model has
Beneficial effect is：Its design structure rationally and is easy to assembling and demolition and maintenance, ceramic lining plate body is wear-resisting, it is heat-resisting,
Corrosion resistance and mechanical strength, shock resistance are forced with long lifespan, high without normal maintenance down operating efficiency, are solved simultaneously
The phenomenon that the inconvenience of traditional structure is safeguarded, the ceramic lining plate for impacting, wearing larger elbow position can be changed according to needs,
Without being changed to overall, reduce financial cost and save maintenance time.
