Description
Technical field
The invention belongs to coke oven, what relate in particular to the coke oven heat tunnel prevents or removes the fouling device.
Background technology
Modern coking coke oven is comprised of coking chamber, combustion chamber and regenerator.The combustion chamber is positioned at the coking chamber both sides, and regenerator is positioned at combustion chamber and bottom of carbonization chamber.Flue is set in the combustion chamber, establishes the lamp holder brick in the flue.Each combustion chamber correspondence of coke oven machine side arranges two groups of coke-oven gas heating pipe lines that connected and composed by lower jet pipe, distribution piping, arm and cock, connect lamp holder brick and coke-oven gas supervisor, two cock control coal gas open and close, wherein one group is advanced heated by gas, another organizes time-out, interval certain hour commutation heating; During the coke-oven gas heating, coal gas is by lamp holder brick ejection burning, and air is imported by the waste gas lobe of cock, enters the combustion chamber through regenerator, air chute.The setting of coke oven coke side connects and composes the mixed gas heating pipe line by arm, fork-shaped pipe connecting, cock, each arm is connected with two waste gas lobes by the fork-shaped pipe connecting, two combustion chambers of corresponding supply connect coal gas chute and mixed gas supervisor, are opened and closed by cock control mixed gas.During the mixed gas heating, mixed gas and air import by the waste gas lobe of cock, enter combustion chambers burn through corresponding chute respectively after the regenerator preheating.
1000 ℃ of the flue of the super-huge coke oven that 7m is above and chute upper temp average out tos.Owing to containing CO, CO in the heating gas
2At high temperature easily cause the polymerization of C and sintering with carbonaceous materials such as the bitter edible plant, benzene, final greying is stopped up lamp holder brick and chute mouth.At present existing coke oven majority is taked the mode de-carbon of natural inflow, only establishes the de-carbon hole at the cock of pusher side coke-oven gas heating pipe line, after the heating commutation, coal gas is cut off, and connects air, under system's suction, ambient air enters this to heating pipe line through the de-carbon hole, carries out de-carbon.
The defective that exists is: system's suction is little, and the air amount amount is few, and flow velocity is slow, and the de-carbon weak effect is difficult to satisfy the de-carbon requirement of super-huge coke oven.The heating of employing coke-oven gas, cold season, ambient air temp was low, and the coke-oven gas temperature of delay is reduced, and caused phlegma to fold and stopped up lower jet pipe; The air mixed of residual coal gas and rising between commutation period easily produces local " detonation ", damages body of heater, servicing time is long, often, maintenance cost is high, affects coking production; Outside the de-carbon hole is directly exposed to, there is unsafe factor.The heating of employing mixed gas, existing coke oven does not have corresponding de-carbon measure, and for super-huge coke oven, the mixed ratio of its coke-oven gas ginseng reaches more than 8%, also easily ties carbon on lamp holder brick and the chute and stops up.
Summary of the invention
The defective that exists in order to overcome prior art, the purpose of this invention is to provide a kind of super-huge coke oven and force carbon removing device, totally-enclosed forced ventilation purges de-carbon, improves the de-carbon effect, avoids or reduce lamp holder brick and the carbon obstruction of chute mouth knot and gas liquor folding obstruction; Avoid local " detonation " to damage body of heater, prolong coke oven work-ing life, reduce maintenance cost and time, guarantee that coke oven production carries out smoothly.
Super-huge coke oven is forced carbon removing device, comprise that each combustion chamber correspondence of pusher side arranges two groups of coke-oven gas heating pipe lines that connected and composed by lower jet pipe, distribution piping, arm and cock, connect lamp holder brick and coke-oven gas supervisor, two cock control coal gas open and close, wherein one group is advanced heated by gas, another organizes stopped heating, interval certain hour commutation heating; The mixed gas heating pipe line that the coke side setting is made of arm, fork-shaped pipe connecting, cock, each arm is connected with two waste gas lobes by the fork-shaped pipe connecting, corresponding two combustion chambers of supplying with connect coal gas chute and mixed gas supervisor, are opened and closed by cock control mixed gas.Be characterized in that the de-carbon air processor that is made of with air preheater the purifying air pressurizing device is connected with the de-carbon air main of pusher side setting, the de-carbon air main that coke side arranges; Pusher side cock gas inlet place establishes hot plate unit, is connected with pusher side de-carbon air main by the de-carbon airline, and during the coke-oven gas heating, the de-carbon air enters the combustion chamber by this pipeline, and chute and lamp holder brick are carried out brute force purging de-carbon; Coke side cock gas inlet place establishes orifice fitting, is connected with coke side de-carbon air main by the de-carbon airline, and during the mixed gas heating, the de-carbon air enters the combustion chamber by this pipe, chute is carried out brute force purge de-carbon.
The present invention further improves, and described de-carbon airline is connected and composed by metallic hose, valve, air arm, and an end is connected with hot plate unit, and the other end is connected with pusher side/coke side de-carbon air main; Adopt flange to connect between above-mentioned pipeline, valve and the hot plate unit, both guaranteed line seal, again easy access dismounting.
The present invention further improves, described air preheater is connected and composed by pressure regulator valve, steam motorized valve and the vapor preheater pipeline that is provided with water discharge valve, low-pressure steam is adjusted pressure through pressure regulator valve, enter vapor preheater by steam motorized valve control flow, the phlegma of separating out after the heat exchange is discharged by water discharge valve; Also establish thermometer, upstream pressure table, downstream pressure table on the steam-pipe, in time detect the temperature and pressure of steam, so that the trouble-free operation of regulation and control air preheater.
The present invention further improves, and described vapor preheater is made of tank body outsourcing lagging material, the built-in spirrillum heating tube of sealing, is connected with steam-pipe, water discharge valve outward; Tank body is established the de-carbon air inlet and outlet, and import is connected with front three-way pipeline, and outlet is connected with three-way pipeline, and the de-carbon air main of pusher side and coke side is connected on the threeway opposite side two ends through de-carbon air motorized valve.
The present invention further improves, described purifying air pressurizing device by strainer, de-carbon blower fan, machine after motorized valve connect and compose, be connected with the de-carbon air intlet pipeline of vapor preheater tank body, the different opening of motorized valve after the reconditioner, automatically control different steps de-carbon air total amount, air filters through strainer, can avoid impurity such as coke powder, dust in the ambient air to enter carbon removing device and the heat tunnel obstruction accident that causes occurs; Enter vapor preheater through filtered air by de-carbon blower fan pressurization, be preheated to 80 ℃ ± 5 ℃, to reduce the temperature head with stack gases, avoid in cold season phlegma to separate out blocking pipe.Sound damper also is set on the air line abates the noise, tensimeter detects the pressure condition of de-carbon air behind the front tensimeter of the machine that arranges and the machine.
