One, raw material is prepared
Generally being lower than 15% various shell skins with moisture content is raw material, through screening, removal of impurities fed to boiler, the first step preheating, the second step charing, the activation of the 3rd step, feed water vapour after, come out of the stove by production quality product the requirements different time of employing.
Two, charing working specification:
Want the scrutiny equipment components before the start, guarantee that crane is in normal service condition, guarantee raw material abundance in the intake chute, check the vision slit (seeing the position of normal temps in the stove) at each position, check the gentle pressure of feedwater, guarantee boiler water yield abundance, guarantee the used quantity of steam of boiler.
Three, activation act rules:
This stove is a kind of novel furnace, is the novel vertical type stove of collection charing, activation integral, adopts raw materials for production directly into stove, provides thermal source and power without coal, electricity etc. during ordinary production, is smokeless environment-friendly type stove.But the burning fume that the charing stage produces enters activation section and burns, and makes the temperature of activation section in the stove reach 900-1100 ℃, promotes that the charing raw material fully activates in the activation section.Utilize the waste heat of stove itself that steam boiler is heated up simultaneously, the activated media (water vapour) that steam boiler produces returns activation section activation pore-creating in the stove, improves the activated carbon product quality.The compound combustible gases such as carbon monoxide that activation stage produces enter and carry out secondary after flue and the combination with oxygen and fully burn, and have thoroughly solved the traditional burner problem not up to standard of discharging fume.
Furnace structure: stove physical dimension (length * wide * height) is about 935 * 328 * 698mm, being respectively quarl, common refractory brick and ordinary red brick from inside to outside is built into, be with the fastening body of heater of joist steel and channel-section steel outward, stove divides from function: mainly contain six parts such as preheating section, charing section, activation section, heat accumulation chamber, combustion chamber, quirk and form.
Activated bath: be the position of carrying out charing, priming reaction in the Activated Carbon Production process, have 28 in the stove by the brick activated bath that becomes of quarl and king's word, four is one group, clean long 0.58 * 0.08 * 245mm of each activated bath * 4, the activated bath end opening is communicated with dump box, and dump box has twice plate up and down, manufactures with steel plate, at the bottom of activated bath and the position, upper end of dump box, be provided with the superheated vapour import.
Combustion chamber and quirk system: the combustion chamber is at the body of heater opposite side, in be built into refractory brick, external application common brick, 80 * 210mm cigarette duct of combustion chamber, every flue divides the upper, middle and lower composition, in the stove in two sub-sections, upper flue divides five flue groups, enters the combustion chamber respectively, flue from combustion chamber branch twice cigarette enters, from top to down, enter down the combustion chamber one, flue gas enters boiler and fully burns and make vapour from the combustion chamber, enters in the high chimney that is built into ordinary red brick more than 25 meters again.
Charing, activated gas system: in charing, reactivation process, produce a large amount of mixed gass based on hydrogen, carbon monoxide, carbonic acid gas etc., by entering horizontal flue, quirk in the activated bath slit, in flue and quirk, burn required temperature when guaranteeing charing, activation.
The steam steam-supplying system: pressure is 176.56-294.2 K p2 water vapour is heated to through steam boiler and produces the activated media high-temperature vapor about 200-500 ℃, high-temperature vapor enters in the activated bath by 28 overheated steam pipes in the quirk again, can with the raw material adverse current, also can following current add, promote the carrying out of priming reaction.
Material flow: the blanking pond of raw material being mentioned furnace roof by chain bucket, through preheating, drying (300-400 ℃), enter charing section (400-700 ℃), activation section (700-1100 ℃) again, (30-80 minute) blanking once at regular intervals according to different material and quality product.Product after the activation can carry out processing treatment through technologies such as aftertreatments again to cooling section (1100-200 ℃) product discharging after cooling off.
Specific operation process:
A, start-up of the furnace and rules:
Baker operation and rules: baker is to keep charing, activation furnace normally to move, and increases the service life and important measures, newly builds after stove and the blowing out blow-on again and all will carry out baker, and is particularly important with the baker of new block stove.Will unscrew the screw of all fastening bodies of heater before the baker, the flange of various pipelines is laid down, and furnace roof cover plate (opening for feed) discharge opening and inspection port is all opened, to guarantee that the intravital moisture of stove is discharged smoothly.For stove is damaged, when heating stove, requirement to slowly heat, and strict (heating curve is according to the physico-chemical property of refractory materials and the coefficient of expansion, furnace binding and gross weight by heating curve, determine the temperature measurement location of baker, factors such as block stove seasoning time are formulated) heat up.Will prevent in the baker process that furnace temperature from descending, baker begins with little fiery baker, treat that furnace temperature rises to a certain degree after, add big fire and heat up.
Loading operation and rules: when furnace temperature is raised to 600 ℃, close discharge port, reinforced each fire door that is sent to stove, temperature is above 700 ℃ in the middle part of activation section, and the activation section combustion chamber has 2/3 to be burnt when red in the observation stove, begins to feed in raw material, till charing section and activation section raw material are filled it up with.It is fast that when filling with substance is wanted, and will be rapidly heated after feeding in raw material, red when the raw material burning, can feed a small amount of water vapor, along with the rising of temperature is filled it up with raw material gradually, when activation temperature reaches more than 900 degree, changes normal running over to.At this moment, stop using the combustion chamber, add sealing immediately behind the fuel, the gas in the activation section by the chimney nature draft send into the quirk internal combustion, the activation certain hour is determined the discharging time for the first time according to temperature, off quality returning reactivates.
Discharging operation and rules: the discharging personnel will open upper flashboard earlier according to quality product blanking on time during discharging, charcoal is discharged on the lower flashboard, turn off upper flashboard then, open lower flashboard again.To in time turn off lower flashboard after unloading charcoal, should feed in raw material immediately after the discharging, check boiler water level, water vapour pressure etc.
B. normal running and rules:
Activation temperature should strict be regulated and control by processing requirement, in order to make the activation furnace temperature remain on certain limit, should adjust each air intlet and steam valve according to the furnace temperature situation, empirical evidence: the temperature of overheated steam has remarkably influenced to the adsorptive power of gac, the temperature of activator is high more, the adsorptive power of gac is high more, therefore wishes that the temperature of water vapour is high more good more.But the water vapor temperature of superheat often is subjected to the restriction of steam superheating sealing material.
Soak time: determine to unload the charcoal time according to the difference of product absorption property, it is 30-80 minute that each activated bath is adorned charcoal pitch time at every turn.
