Accompanying drawing is the utility model structural representation.
Embodiment:
The utility model structure comprises that the air introducing port that coke dry quenching furnace 2 is provided with is communicated with the source of the gas pipe through air importing valve; Coke dry quenching furnace 2 air outlets are communicated with disposable dust remover 3 inlet mouth pipelines; Disposable dust remover 3 air outlets are communicated with boiler 4 inlet mouth pipelines; Boiler 4 air outlets are communicated with secondary filter 5 inlet mouth pipelines; Secondary filter 5 air outlets are communicated with recirculation blower 6 inlet mouth pipelines; Recirculation blower 6 venting ports are communicated with hot tube heat exchanger 8 inlet mouth pipelines, and hot tube heat exchanger 8 air outlets are communicated with coke dry quenching furnace 2 inlet mouth pipelines, it is characterized in that: the detecting head pipeline connection through a threeway and a gas analyzer 7 on recirculation blower 6 venting ports and pipeline that hot tube heat exchanger 8 inlet mouths are communicated with; It is solenoid valve 1 that air imports valve; The information output of gas analyzer 7 is communicated with the PLC cpu of setting up 9 information input terminal circuits, and the information output of PLC cpu 9 is communicated with the information input terminal circuit of solenoid valve 1.
Write the feedback regulation program at dry-quenching automatic EI master interface; According to gas analyzer 7 data be: set up through cycle gas composition and adjusting and import the mathematical model that air capacity realizes controlling the dry coke quenching burn out rate through the meter technical scheme that the utility model adopted; And realize that based on EI automation control system programming the real-time control of dry coke quenching burn out rate calculates the result, and utilize PLC cpu 9 to regulate the structure that the air import volumes are realized the control of dry coke quenching rates.
Our dry coke quenching adopts the combustiblecomponents of the effective Control Circulation gas of method that combustion method and nitrogen input method combine, and it is better to reach the dry quenching system feasibility of controlling the coke burn out rate that control imports air capacity.We gather the data that provide in real time according to the online gas analyzer 7 that dry coke quenching is arranged on recirculation blower 6 outlets; The control computer expert crosses written program calculating in the input; Feed back to the dried bolt solenoid valve 1 in the stove that puts out; And utilize PLC cpu 9 to regulate automatically, set up the control that recycle gas and air import the model of mind realization dry coke quenching charcoal burn out rate between the valve opening.
Principle is following: for keeping the gas steady flow, when the limit imports air, must efflux partly flue gas, make recycle gas keep certain amount to reach running balance.And the process of coke scaling loss is the process that the carbon of participating in reaction " is taken away " by the airborne oxygen element of import institute, and the burn out rate of corresponding coke then can be regarded as the speed that solid-state " carbon " is converted into gasiform " carbon ".Because oxygen element content remains unchanged basically in the system, the bound gas composition changes fast characteristics, can setting up gaseous constituent according to the material balance of oxygen, to calculate the mathematical model of dry coke quenching burn out rate in real time following:
