Abstract
The present invention relates to a kind of methods for carrying out freshening to dross using coke drum, including following step S1: starting dross pump conveys dross into coke drum along 10 meters of dross valves；S2: dross enters coke drum after twenty minutes, and starting water pump confirms that coke cooling water into after coke drum, is closed to steam valve toward coke drum water supply；S3: by heating up to coke drum, temperature rises to 450 DEG C -500 DEG C and carries out freshening to dross；Daily freshening amount can be greatly improved using this method, company dross inventory is effectively relieved, and strong reduction environmental protection pressure has reached desired effect.
Description
Technical field
The present invention relates to a kind of dross freshening methods, are specifically related to a kind of side for carrying out freshening to dross using coke drum
Method.
Background technique
Workshop dross inventory is high, and there are immense pressure, daily 18 tons of the freshenings in coking workshop for environmental protection operation facility
Amount, cannot effectively alleviate current driving force workshop dross inventory problem and environmental protection pressure.Coking dross freshening flowmeter limitation,
It is returned back out in the freshening later period existing, it will be apparent that pipeline vibration, there are security risks；So designing a kind of application to solve the above-mentioned problems
The method that coke drum carries out freshening to dross is just particularly important.
Summary of the invention
The present invention can stop dross freshening after coke drum freshening temperature is down to 290 DEG C immediately, avoid the occurrence of dross in coke
The case where cannot being reacted completely in charcoal tower.During dross blowback is refined, it must contact, prevent with power houses in time when changing process
Pump builds the pressure；A kind of method carrying out freshening to dross using coke drum is provided.
In order to solve the above technical problems, the present invention provides it is a kind of using coke drum to dross carry out freshening method,
It is characterized by comprising following steps:
S1: starting dross pump conveys dross into coke drum along 10 meters of dross valves；
S2: dross enters coke drum after twenty minutes, starting water pump toward coke drum water supply, confirm coke cooling water into after coke drum,
It closes to steam valve；
S3: by heating up to coke drum, temperature rises to 450 DEG C -500 DEG C and carries out freshening to dross.
Further, post personnel observes 10 meters of dross valve feedwater line site pressure expression conditions, pressure in the step S1
Power rise after open water valve, give vapour amount keep 2.5-3t/h.
Further: in the step S2, confluent maintains 25t/h or so, and dross freshening amount keeps 45t/h, and
The rear stopping dross pump at freshening 15 minutes or so, and close dross valve.
Further: in the step S3, observe top of coke tower pressure and temperature, pressure rise it is too fast when can reduce to
Water, after temperature is down to 290 DEG C, it is necessary to stop dross freshening at once.
After adopting the above structure, the present invention can stop dross freshening after coke drum freshening temperature is down to 290 DEG C immediately, keep away
Exempt from the case where dross cannot react completely in coke drum occur.It, must be in time and dynamic when changing process during dross blowback is refined
The connection of power workshop, prevents pump from building the pressure；And daily freshening amount can be greatly improved using this method, company's dross library is effectively relieved
It deposits, strong reduction environmental protection pressure has reached desired effect.
Specific embodiment
The present invention provides a kind of methods for carrying out freshening to dross using coke drum:
S1: starting dross pump conveys dross into coke drum along 10 meters of dross valves；
S2: dross enters coke drum after twenty minutes, starting water pump toward coke drum water supply, confirm coke cooling water into after coke drum,
It closes to steam valve；
S3: by heating up to coke drum, temperature rises to 450 DEG C -500 DEG C and carries out freshening to dross.
In above-mentioned step S1, post personnel observes 10 meters of dross valve feedwater line site pressure expression conditions, and pressure rises
Afterwards open water valve, give vapour amount keep 2.5-3t/h.
In above-mentioned step S2, confluent maintains 25t/h or so, and dross freshening amount keeps 45t/h, and divides in freshening 15
The rear stopping dross pump of clock or so, and close dross valve.
In above-mentioned step S3, top of coke tower pressure and temperature is observed, pressure can reduce confluent, temperature when rising too fast
After being down to 290 DEG C, it is necessary to stop dross freshening at once.
In conclusion the present invention can stop dross freshening after coke drum freshening temperature is down to 290 DEG C immediately, avoid the occurrence of
The case where dross cannot react completely in coke drum.It, must timely and power houses when changing process during dross blowback is refined
Connection prevents pump from building the pressure；And daily freshening amount can be greatly improved using this method, company dross inventory is effectively relieved, has
The reduction environmental protection pressure of power, has reached desired effect.
