Description
Technical field
The utility model is related to mineral hot furnace waste heat boiler technical field, and in particular to a kind of flexible deashing rag deashing
The horizontal mineral hot furnace waste heat boiler of device.
Background technology
Mineral hot furnace occupies very important status in industrial furnace system, and it mainly includes ferrosilicon, ferrochrome, silicomanganese, work
The ore deposit heat boiler such as industry silicon, according to Over About Chinese Ferroalloy Industry association relevant statistics, China is the first in the world ferroalloy big producer,
National 2435.5 ten thousand tons of ferroalloy yield in 2010, increases by 10.23% on a year-on-year basis, accounts for more than the 50% of World Ferroalloy total output.
The product of China's the ferroalloy industry 90% or so is produced using mineral hot furnace electrothermal way, and energy resource consumption is higher, is national energy-saving emission reduction
Key industry.The power consumption of mineral hot furnace accounts for the 2% of national generating capacity, and power consumption receives much concern, and how to make full use of ore deposit heat
The waste heat of stove, is the power-saving technology that a country actively encourages to widely popularize using cogeneration technology, not only saves the energy, more
Be conducive to environmental protection.Therefore, promote the field transformation and grassroot project mineral hot furnace constantly towards boiler UTILIZATION OF VESIDUAL HEAT IN and
Develop under the main trend of clean burning and improve.
During the ore deposit heat boiler electric furnace smelting such as ferrosilicon, industrial silicon, the waste heat smoke components produced by it, which are removed, mainly to be included
Outside the gas componants such as vapor, carbon dioxide, oxygen, nitrogen, sulfur dioxide, also containing with SiO2Based on (being commonly called as silicon powder)
The exhaust gas dust of composition is wanted, these exhaust gas dust average grain diameters only have 200~400nm, very carefully, and dust content concentration is higher, there is 8
~12g/Nm3, specific surface area is big, and thermal insulation is strong, light weight and very glutinous, easily adsorbs and has electrostatic, and its cohesiveness is with temperature
The rise of degree and strengthen, therefore mineral hot furnace waste heat boiler easily deposits in boiler heat exchange tube wall, adheres to above-mentioned exhaust gas dust, greatly
Big heat exchange, the heat transfer efficiency for reducing boiler, reduces the utilization rate of boiler afterheat, thus in terms of mineral hot furnace UTILIZATION OF VESIDUAL HEAT IN,
It is also mineral hot furnace waste heat always using this timely and effectively to remove the exhaust gas dust during boiler works and improve its fume afterheat
The key technology that boiler is studied.
Existing mineral hot furnace waste heat reset mode mainly has steel ball deashing, shock-wave ash-clearing and mechanical tube brush deashing, and steel ball is clear
Grey mode need not set deashing device due to interbank, and its manufacture requires low, because it dispatches from the factory for loose mail, transport into also that this is low,
But clean, deashing rate is not below 60% for steel ball deashing, and steel ball and carbon particle enter SILICA FUME, and sintering caking is easily caused cigarette
Gas channel blockage, while high-altitude is overturned during steel ball lifting system accident, is easily caused personnel casualty accidentses；Shock-wave ash-clearing mode second
Alkynes consumption is very big, and operating cost expense is very high, and deashing is not thorough, and high fume temperature, utilization rate of waste heat is low, it is impossible to adapt to ore deposit
The need for hot stove furnace UTILIZATION OF VESIDUAL HEAT IN.
Mechanical tube brush purge mode is the focus studied at this stage in each ash-clearing technology, and its cleaning efficiency is of a relatively high；Example
Such as, Chinese patent CN104296592A discloses a kind of mechanical airflow formula exchanging pipe of boiler by waste clearing apparatus, and it cleans dress
Put including two clamping limbs, metal steel wire cleaning ball and steel wire lump state keeper, its steel wire lump state keeper and metallic steel
Silk cleaning ball is abutted against；Chinese patent CN201555501U also discloses a kind of exchanging pipe of boiler by waste group and filled with mechanical sweeper
Put, it includes deashing brush holder, brush holder elevating mechanism etc., and dust cleaning brush is set on deashing brush holder, in the reciprocal fortune of brush holder elevating mechanism
Act the every heat exchanger tube with lower cleaning set of heat exchange tubes；Chinese patent CN 204922925U disclose a kind of heating furnace flue waste heat
Recovery boiler prevents the steel brush ash-cleaning device of dust stratification, and it includes enclosing the steel structure frame for being located at boiler tube bundle periphery, shuttled
Girder steel between boiler tube bundle in neutral gear, and the stainless steel brush on the girder steel, the girder steel is in each neutral gear
It is equidirectional arranged in parallel, and be upper and lower, upper and lower rule dislocation arrangement, every 4 stainless steel brushes surround a boiler
Tube bank；Chinese patent CN202733862U discloses a kind of hot waste heat boiler of horizontal ore deposit with brusher deashing device, the waste heat
The deashing device of boiler is equally the fixing device with a frame-type brush, provided with upper and lower ends point in its fixing device
Multiple wire brushes on framework are not fixed on, and the brush fixing device of the frame-type moves up and down under the driving of transmission mechanism
Carry out deashing.
Above-mentioned cited patent document its be heat exchanger tube using the brush deashing mechanism of mechanical tube to waste heat boiler
Cleaned, and partial monopoly also discloses that its brush is fixed on brush holder for multiple stainless steel brushes or steel wire ball brush, in transmission
Under the motion of drive mechanism, brush holder moves back and forth and its heat exchanger tube is cleaned, but existing above-mentioned mechanical tube brush cleaner
Its order of contact and coverage degree, the lifting type of drive of steel wire brush holder, steel wire not no to wire brush or steel wire ball brush and heat exchanger tube
Brush or steel wire lump material etc. are rationally designed, or even also unclear to tube brush to the modes of emplacement (vertical or horizontal) of waste heat boiler
The influence of grey mode is accounted for, therefore already to there is cleaning efficiency not high enough for the mechanical tube brush purge mode of existing waste heat boiler
The service life of (being not reaching to more than 99%), wire brush or steel wire ball brush is short, and brush such as is inconvenient to change at the technical problem.
The first CN103471073A of granted patent of the related invention people of the application discloses a kind of with multiple vertical
The waste heat boiler of module, the waste heat boiler has mechanical brush ash removing mechanism, and several heat exchanger tubes of the deashing mechanism have edge
The coiled pipe membrane wall structure of horizontal direction arrangement or the multilayer tube bundle unit of single extended surface tube structure composition, hanging is installed on every
Between two layers of tube bundle unit can the dust stratification of horizontal direction reciprocating bar shaped brush unit exchange heat pipe wall cleaned with water；But hair
Person of good sense institute it is found out that, the vertical exhaust-heat boiler is when using mechanical tube brush purge mode deashing, in prolonged deashing process
The boiler heat exchange pipe of horizontality is bent because the weight body of itself easily dangles along position of centre of gravity, makes the bar of horizontal reciprocating movement
Shape brush unit is easily stuck so that the cleaning efficiency of the mechanical brush ash removing mechanism of vertical exhaust-heat boiler has declined.
