Technical field
This utility model belongs to coal drying and dehydrating device field, is specifically related to a kind of coal handling system coal-fired dewatering system online.
Background technology
Boiler as-fired coal moisture is too high is one of subject matter restricting boiler economic operation.As-fired coal moisture is too high, makes coal pulverizer
Output drop, power consumption increases；Raw coal moisture height makes the free-running property of coal be deteriorated, and causes stokehold coal bunker, coal spout felt jam, fortune
Row blocks, has a strong impact on coal-supply system and run.Former moisture in coal is too high, causes boiler combustion room temperature to reduce, coal dust
Ignition point is postponed, and flue gas volume increases, so that heat loss due to exhaust gas increases, aggravates the cold end corrosion of back-end surfaces, pot simultaneously
The efficiency of furnace reduces.
At present, power plant or heating plant result of the above problems are mainly by solving as-fired coal moisture mistake at coal yard blending dry coal
High problem, but exist trucking expenses increase, mix uneven, cannot accurately regulate moisture, less economical.
Summary of the invention
The purpose of this utility model is to provide a kind of wet dust removal, online dry, the coal handling system fire coal online of good energy saving property to take off
Water system.
This utility model solves its technical problem and be the technical scheme is that a kind of coal handling system coal-fired dewatering system, bag online
Include No. 1 ribbon conveyer of plant area, surge bunker, steam rotary dryer, No. 2 ribbon conveyers of plant area, described plant area 1 band
Formula conveyer is provided with belt plow, is provided with surge bunker below belt plow, and the discharging opening of surge bunker passes through 1# belt conveying
Machine is connected with feeding spiral conveyer, and feeding spiral conveyer is connected with air preheater, and feeding spiral conveyer also returns with steam
The entrance turning drying machine connects, and the outlet of steam rotary dryer passes sequentially through 2# ribbon conveyer, 3# ribbon conveyer with electronic
No. 2 ribbon conveyers of threeway and plant area are connected, and the top of steam rotary dryer connects wet scrubber, and wet scrubber leads to
Cross air-introduced machine to be connected with exhaust duct.
Specifically, the top of described surge bunker connects has storehouse to push up sack cleaner.
Specifically, described air preheater is provided with steam inlet and natural air entrance, the bottom of air preheater and condensate pipe
Net connects.
Specifically, described 3# ribbon conveyer is arranged over transfer station sack cleaner.
With plant area's exhaust steam as thermal source, by indirect type heat transfer type, the heat of steam is passed to granule, after granule absorbs heat
Temperature raises.Material raises along with temperature, completes to be dried in steam rotary dryer.Hot blast and the steam of dry run are drawing
Wet scrubber is entered with this under fan action, after degree of depth dedusting, a small amount of solid dust carried secretly in the lower tail gas of washing, tail gas
Qualified discharge.
This utility model has the advantages that online coal-fired dewatering system of the present utility model uses steam drying, with exhaust steam
For the former coal handling system seamless link of thermal source, good energy saving property, and plant area, according to plant area's Actual combustion coal consumption, it is achieved course of conveying
Online dehydration, adjusts coal-fired moisture the most in time, and system structure is simple and reliable, and security performance is high, high-efficient wet-type dedusting,
Environment protection standard.
