A kind of situation that the coking production technology comes to this.The testing coke oven of conventional coke making process is the intermittent type chamber type coke furnace.In the coking production process, the discharge capacity of raw coke oven gas changes along with the difference of process of coking, and at the coking initial stage, the discharge capacity of raw coke oven gas is big, and the pressure in the coke oven is big, and is not smooth if raw coke oven gas is dredged, and can cause furnace roof, fire door to run cigarette and burn with anger befouling environment; In the mid-term of coking, the volatile substance in the coal charge is discharged gradually, and the discharge capacity of raw coke oven gas reduces gradually; In the latter stage of coking, the raw coke oven gas major part is the gas of Pintsch process, and the coal gas amount is very little, need in time close the asending pipe valve, keep the slight positive pressure state in the coke oven, otherwise can make air enter coke oven, burn the coke in the coke oven, influence production testing.
Exist than big-difference because each time period of coking process produces the coal gas amount, keep stable for making the coke oven production testing, its key issue is and must carries out real-time regulated to carbonization chamber pressure.
For avoiding carbonization chamber negative pressure to occur, normal by the artificial method of adjusting at any time of observing at any time, according to the pressure gauge that detects asending pipe, the asending pipe valve opening is put in order in messenger's wage adjustment, but not only waste time and energy by manual tune, and precision and the amplitude adjusted are difficult to effective control.
Patent " medium-sized electric heating testing coke oven " has adopted the automatic pressure detection system, adjust the aperture of asending pipe valve according to automatic detected pressure value, solved self-adjusting problem like this, but pressure detecting system is worked under the bigger raw coke oven gas environment of dust loading for a long time, usually cause and detect a mouthful calculus China ink, detect a mouthful obstruction, thereby have influence on the precision of detection, therefore the accuracy of adjusting the asending pipe valve according to automatic detected pressure also is affected, pressure that can not better controlled coke oven carbonization chamber.
Summary of the invention
Various problems at present Pressure testing control valve existence, the inventor provides a kind of temperaturing control pressure valve, comprise temperature transducer, controller, executor, described temperature transducer collecting temperature signal, and temperature signal is passed to controller, the control module in the controller is to the temperature signal analysing and processing, and is converted into command signal, be passed to executor, executor drives the gas flow adjusting means running.Thereby the control of pressure valve is converted into temperature detection by Pressure testing, because the Fluid Volume difference, its temperature certainly exists difference, and the size that how much has determined hydrodynamic pressure of Fluid Volume, so the direct size of reacting fluid pressure of fluid temperature (F.T.).In view of the above, at first the pressure criteria in the enclosed space is converted into temperature standard, and this temperature standard is preset in the middle of the control module of controller, after receiving the temperature signal that the temperature transducer collection transmits, by with preset temperature comparison, and then the signal of giving an order, be passed to executor, and have executor to drive the controlling device running, and then the fluid flow amount of control confined space, keep the stable of confined space pressure.
As the application of this temperaturing control pressure valve in coke oven, the inventor has done further adaptation, comprise temperature transducer, controller, executor, described temperature transducer links to each other with the asending pipe of coke furnace carbonization chamber, described executor links to each other with the asending pipe valve of coke furnace carbonization chamber, temperature signal in the described temperature transducer online acquisition asending pipe, and temperature signal is passed to controller, control module in the controller is to the temperature signal analysing and processing, and be converted into command signal, and being passed to executor, executor drives the asending pipe valve event.At the coking initial stage, the discharge capacity of raw coke oven gas is big, and the pressure in the coke oven is big, temperature is high, and the control module in the controller requires executor to drive the increase of asending pipe valve opening, thereby increases Throughput, avoids furnace roof, fire door to run cigarette and burns with anger befouling environment; In the mid-term of coking, the volatile substance in the coal charge is discharged gradually, and the discharge capacity of raw coke oven gas reduces gradually, thereby its temperature reduces, and the control module in the controller is by the analysing and processing to temperature, and the command action device drives the asending pipe valve opening and reduces; In the latter stage of coking, the raw coke oven gas major part is the gas of Pintsch process, the coal gas amount is very little, temperature is very low, controller is after to this low temperature analysing and processing, send the order of closing the asending pipe valve, thereby keep the slight positive pressure state in the coke oven, avoid air to enter coke oven, burn the coke in the coke oven, influence production testing.Thereby real-time, the adjusting automatically of asending pipe pressure have been realized.
In sum, it is conspicuous adopting the beneficial effect that the present invention produced, and at first, adopts the automatic controller of asending pipe valve, has replaced manual control, has saved human resources, has improved the accuracy of control; Secondly, adopt temperature control to replace traditional pressure control, avoided the detection error that causes because of Pressure testing surface calculus China ink; At last, temperature variation and carbonization chamber internal pressure are connected, and the environment of temperature detection adaptation dust, testing precision is higher, has satisfied pressure controlled requirement.
