Abstract
Cork dry quenching disposable dust remover material-level detecting device, it comprises the gas meter 3 of detector tube 2, lower limit alarm switch, it is characterized in that: before the air intake opening of gas meter 3, be provided with a gas distributing chamber 4, gas distributing chamber 4 has pipeline to connect Nitrogen source gases, described pipeline is provided with throttling valve 5, and described gas distributing chamber 4 also has a gas outlet 6 to lead to air, in addition, detector tube is provided with an arm and leads to air, and described arm is provided with solenoid valve 7.Be provided with gas distributing chamber 4 before the air intake opening of this material-level detecting device due to gas meter 3 and be connected with nitrogen thus avoid pass into air cause high temperature coke powder burn make material-level measure forbidden, in addition, can be purged detector tube 2 by the solenoid valve 7 opened on arm, avoid pipeline blocked, improve the reliability of pick-up unit.
Description
Technical field the utility model relates to a kind of cork dry quenching disposable dust remover material-level detecting device, is particularly applied in the material-level detecting device on the disposable dust remover of coke-oven plant's CDQ device.
The feed bin of the disposable dust remover of background technology coke-oven plant CDQ device must install material-level detecting device, to detect material level in time, dedusting ash has expired will unload ash in time, prevent dust stratification from too much being taken in waste heat boiler by the recyclegas in the dry coke quenching circulation system and wash away boiler tube, boiler tube is washed wearing and tearing and easily causes the serious accidents such as boiler tube bursting.Be temperature close to the high temperature coke powder of 1000 degrees Celsius due to what fill in the feed bin of disposable dust remover, therefore, what current each factory used is condenser type high temperature level-sensing device mostly.From service condition, this high temperature level-sensing device failure rate is higher, damages frequently and often causes disposable dust remover normally not produce, and has even jeopardized the safe operation of waste heat boiler, and this high temperature level-sensing device price is higher, frequent replacing can bring the rising of production cost.Therefore, someone devises and utilizes the suction of the negative pressure in disposable dust remover air also to detect the method for suction air capacity to detect material level, the device that the method relates to mainly comprises the gas meter of a lower limit alarm switch, principle of work is: the air mass flow sucking detect aperture during hole capital after selling all securities is large, and flowmeter is not reported to the police; When buying securities with all one's capital, detect aperture is blocked, and inhalation flow is little, and flowmeter and alarm indication storehouse are completely.The shortcoming that this device exists is: owing in ash silo being high temperature coke powder, can burn after sucking air, so the coke powder around detect aperture can be burnt, in addition, working time is of a specified duration, have coke powder in detect aperture and pipeline to retain, above factor all can the reliability of negative effect accuracy of detection and plant running.
Summary of the invention the purpose of this utility model is to provide a kind of cork dry quenching disposable dust remover material-level detecting device, it can not coke powder around combustion supervision hole, also can regularly purge detect aperture and pipeline, so avoid pass into air cause high temperature coke powder burn make detection material level forbidden, also avoid pipeline blocked, improve the reliability of pick-up unit.A gas distributing chamber is provided with before the air intake opening that the purpose of this utility model is achieved in that gas meter, gas distributing chamber has pipeline to connect Nitrogen source gases, described pipeline is provided with throttling valve, described gas distributing chamber also has a gas outlet to lead to air, in addition, detector tube is provided with an arm, and described arm is provided with solenoid valve.This material-level detecting device is owing to being provided with gas distributing chamber before flowmeter air intake opening and being connected with nitrogen, the gas of suction gas flowmeter is made to be all nitrogen, avoid pass into air cause high temperature coke powder burn make detection material level forbidden, in addition, the solenoid valve regularly opened on arm can purge detector tube, pipeline can be avoided so blocked, improve the reliability of pick-up unit.
Appended drawings is the structural representation of embodiment according to the utility model proposes, and in figure, 1 is the coke powder storehouse of cork dry quenching disposable dust remover, and 2 is material-level measure pipes, and 3 is gas meters, and 4 is gas distributing chamber, and 5 is throttling valve.6 is gas outlets of gas distributing chamber, and 7 is purge solenoid valves, and 8 is nitrogen steam lines.
In embodiment embodiment of the present utility model as shown in drawings, the high temperature coke powder got off is removed in coke powder storehouse 1 built with disposable dust remover, the relevant position in coke powder storehouse 1 has material-level measure hole, detector tube 2 is housed outside detect aperture, detector tube 2 connects gas meter 3, gas meter 3 has lower limit alarm switch.When the coke powder in coke powder storehouse 1 few (stifled less than detect aperture), in gas meter 3, gas flow is large, alarm switch does not signal, when coke powder has completely arrived detect aperture, detect aperture is blocked, in gas meter 3, gas flow will reduce, when flow can send signal of buying securities with all one's capital lower than lower limit set value alarm switch.The air intake opening of gas meter 3 meets gas distributing chamber 4, and it is throttling valve that gas distributing chamber 4 has pipeline to connect nitrogen steam line 8,5, the adjustable nitrogen flow entered in gas distributing chamber 4.During normal work, under suction function in coke powder storehouse 1, gas in gas distributing chamber 4 is inhaled in coke powder storehouse 1 through gas meter 3, detector tube 2, throttling valve 5 is regulated to make to keep pressure-fired in gas distributing chamber 4, namely the nitrogen in inflow gas distributing chamber 4 is more than the nitrogen be inhaled in coke powder storehouse 1, unnecessary nitrogen overflows from the gas outlet 6 of gas distributing chamber, and can ensure like this to suck in coke powder storehouse 1 is all nitrogen, avoids sucking air and causes high temperature coke powder to burn.
In order to prevent detect aperture and detector tube 2 from being blocked by coke powder, detector tube 2 is provided with arm, and arm is provided with purge solenoid valve 7, and open and can purge detector tube 2 regularly to purge solenoid valve 7 energising, the purge solenoid valve 7 shown in accompanying drawing leads to air.Purge solenoid valve 7 also can lead to nitrogen steam line 8, such supply gas pressure is large, purge large-minded, purge effective, in order to when preventing from purging, nitrogen is oppositely flowed out from gas distributing chamber 4 by gas meter 3, preferably before gas meter 3 or a solenoid valve is set below, open when this solenoid valve normally works, close during purging.
