Description
Technical field
The present invention relates to fluidized-bed combustion boiler equipment technical field more particularly to a kind of electric hoists for fluidized-bed combustion boiler
Device.
Background technology
Circulating fluidized bed boiler is generally divided into forepart and the vertical shaft of tail portion two using single drum, natural circulation mode.Before
Always to hang structure, surrounding is made of portion's vertical shaft fin panel casing.From bottom to top, air compartment, emulsion zone, a dilute-phase zone are followed successively by.
Tail vertical well uses support construction, is connected between two vertical shafts by vertical cyclone separator, separator lower part connection loop back device
And ash cooler.Combustion chamber and separator interior are equipped with abrasionproof liner, forepart vertical shaft Ao's pipe furnace wall, external metal casing,
Tail vertical well light boiler setting bears boiler total weight by eight steel columns.Circulating fluidized bed boiler mainly uses high ash content
Inferior fuel, for coal after hearth combustion, a large amount of grey particle is carried to upper furnace by flue gas, the thicker grey particle of a part
Continue to send burner hearth back to by separator separation, the thinner grey particle of another part cannot be trapped by separator and be escaped, with flue gas
To tail vertical well, tail vertical well lining is equipped with high temperature superheater, reheater, low temperature superheater, economizer, air preheater etc. and changes
Thermal part；This part fine ash particle can all cohere due to various reasons in high temperature superheater, reheater, low temperature superheater, save coal
On the heat exchanger components such as device, air preheater, this phenomenon is " dust stratification "；" dust stratification " can make the heat exchange efficiency of these heat exchanger components big
To reduce or even losing heat exchange function, so as to reduce boiler output, efficiency reduces.In order to avoid the generation of " dust stratification " phenomenon,
Boiler factory would generally use various soot blowers to carry out deashing processing, such as：Steam sootblower, acoustic wave ash ejector, gas explosion pulse
Soot blower, pulse of compressed air soot blower etc. with gradually coming into operation for these soot blowers, make the situation of dust stratification greatly subtract
Gently, good soot blowing effect is played.Especially for the smaller grey particle of those cohesivenesses, effect is especially pronounced.But with
The extension of usage time, the defects of various soot blowers is also completely exposed, and such as steam sootblower soot blowing, blows less than hyperthermia and superheating
The ash at device, reheater, low temperature superheater, economizer, air preheater these heat exchanger components tube bank center, at the end of soot blowing,
Steam, which can condense into water and pass through ash blowing mouth, flows into flue, and ash is made to be set on the pipe of these heat exchanger components and can not remove,
Cause tube failure；For another example pulse of compressed air soot blower soot blowing if the intensity of pulse is excessive, will suffer the sealing of furnace wall
It is damaged, while also has an impact to the health of neighbouring personnel, therefore, pulse of compressed air soot blower is due to strong by pulse
The limitation of degree and pulse wave frequency rate, the effect of soot blowing are had a greatly reduced quality.Also, both soot blowers need to consume mass energy, energy
Consumption is higher.
Publication No. CN 204006043U, publication date disclose one kind for the Chinese patent literature on December 10th, 2014
Boiler steam blowing ash system is related to soot blower system field, including furnace body, air preheater soot blower, steam sootblower main pipe
With SCR soot blowers, it is characterised in that：The furnace body is divided into seven layers, and boiler sootblowing steam is connected on the outside of described seven layers of furnace body of stove
Pipeline, sets that there are one soot blowing manually operated door and a DCS remote operation electrically operated gate, described five layers of stoves of stove on the boiler sootblowing steam pipeline
Ontology is equipped with SCR soot blower jet chimneys, and is equipped with the total manually operated door of SCR soot blowers and pneumatic door, is set on three layers of furnace body of stove
There is air preheater soot blower main air inlet pipe road, the air preheater soot blower main air inlet pipe road is equipped with air inlet pipe manually operated door and check
Door, the air preheater include air inlet pipe and drain pipe, and the drain pipe is equipped with hydrophobic manually operated door and hydrophobic electrically operated gate, the steaming
Vapour soot blower main pipe is equipped with steam soot blowing air source tune valve, and flowmeter is equipped with after the steam soot blowing air source tune valve.
Boiler steam blowing ash system, not only complicated, but also is difficult to blow by steam soot blowing disclosed in the patent document
To the ash at air preheater tube bank center, at the end of soot blowing, steam can condense into water by the ash at air preheater tube bank center
Solidification, causes air preheater to fail, and entire boiler output is caused to reduce, and efficiency reduces.
