Abstract
This invention belongs to the coke oven heating automation control technology, relates to one kind of coke oven heating temperature intelligent control system. Its characteristic lies in: chose the leans 22# in the burnt oven coke, machine leans on the 7# quirk, every other 5 quirks install a thermo-element, the altogether 20-30 thermo-elements, represent the coke oven machine Jiao Ce average temperature with 20-30 thermo-element survey's average temperature, like 1260 degree C; The thermo-element from the coke oven bases upward insertion, installs sets up nearby quirk's coal gas burner nozzle, is apart from coal gas burner nozzle center 30-40mm; Passes to the computer the thermo-element gathering quirk temperature signal, uses the computer rule adjustment furnace temperature, causes the furnace temperature maintains at the given value. This invention may realize the coke oven heating temperature intellectualization control and the closed loop adjustment in different areas, different factories, in the different types of furnace. The furnace temperature may be controlled within +-3 degree C, it can save the heating coal gas, reduce the CO content waste gas, extend the coke oven life.
Description
Technical field
The invention belongs to coke oven heating automated control technology, relate to a kind of coke-oven heating-temperature intelligent control system.
Background technology
Coke-oven heating-temperature control automatically is a complexity and the problem that realizes difficulty.Current coke-oven plant both domestic and external coke oven temperature adjustment is with artificial, with optical pyrometer each quirk is measured, use the manual sorting take off data then, temperature data according to take off data and needs is analyzed, regulate the heating gas amount that adds then, make coke maturation in the stove, this regulate process is called adjusted open loop.The deficiency of artificial adjusted open loop is to measure discontinuously, and everyone collimation error is big, regulates untimelyly, and furnace temperature fluctuation is big, has objectively influenced coke quality, has wasted the energy, has polluted environment.Reported in literature is arranged: thermopair has been installed on flue top, certain coke oven top by Japanese Nippon Steel coke-oven plant, and the temperature mark passes under the stove calculating machine computer and realizes that furnace temperature controls automatically.But because the throat temperature height, the vehicle operation is frequent, and lead is installed difficulty, and lead is often burnt out, and is difficult in maintenance, does not obtain promoting.
Summary of the invention
The present invention has overcome the defective of above-mentioned existence, and purpose is the problem that will solve the coke-oven heating-temperature continuously measured and regulate furnace temperature continuously automatically, does not need manual shift, realizes the closed loop adjustment furnace temperature, and a kind of coke-oven heating-temperature intelligent control system is provided.
Coke-oven heating-temperature intelligent control system content Description of the present invention:
Coke-oven heating-temperature intelligent control system of the present invention, it is characterized in that: be chosen in coke oven coke side 22#, on the pusher side 7# quirk, a thermopair be installed every 5 quirks, totally 20～30 thermopairs are represented the medial temperature of coke oven cokery side with the medial temperature of 20～30 thermocouple measurements;
Thermopair is upwards inserted from the coke oven bottom, be installed near the coal gas burner of flue, apart from coal gas burner center 30～40mm;
The fire path temperature signal of thermopair collection is passed to computer, adopt the computer rule to regulate furnace temperature, make furnace temperature remain on set-point.
The present invention adopts dissimilar coke ovens is surveyed, and understands the furnace temperature Changing Pattern of each coke oven, sets up mathematical model.Because the complicacy of coke oven, interfering factors is many, and expert experience base is set up in the temperature adjustment of the coke oven of different factories, different areas, the different type of furnaces, adds modern control theory with expert database and realizes intelligent control furnace temperature.The present invention can realize the intelligent control of coke-oven heating-temperature on different areas, different factory, the different type of furnace, realize closed loop adjustment, furnace temperature can control ± 3 ℃ with interior, save and add heating gas, reduce CO content in the waste gas, prolong the coke oven life-span.
Description of drawings
Fig. 1 is the coke-oven heating-temperature intelligent control system structural representation
Embodiment
Coke-oven heating-temperature intelligent control system of the present invention is achieved in that the present invention at first will solve the temperature of continuously measured quirk, and where its less important solution measuring sensor thermopair is installed in, and solves once more how thermopair is installed.To realize intelligent control according to heating law with computer at last.Want the continuously measured fire path temperature, thermopair must be installed on quirk.
The present invention is chosen in coke oven coke side 22#, on the pusher side 7# quirk, every 5 quirks a thermopair is installed, and totally 20～30 thermopairs are represented the medial temperature of coke oven cokery side with the medial temperature of 20～30 thermocouple measurements;
Thermopair is upwards inserted from the coke oven bottom, be installed near the coal gas burner of flue, apart from coal gas burner center 30～40mm;
The fire path temperature signal of thermopair collection is passed to computer, adopt the computer rule to regulate furnace temperature, make furnace temperature remain on set-point.
Do below in conjunction with accompanying drawing and to specify
See Fig. 1 coke-oven heating-temperature intelligent control system structural representation, the present invention upwards inserts thermopair from coke oven machine side coke side bottom, pusher side 7#, coke side 22#, every 5 quirks a thermopair is installed, totally 20 thermopairs, thermocouple temperature measurement point is apart from coal gas burner center 30～40mm, both sides thermocouple temperature measurement signal is delivered to computer, as 1260 ℃; 1261 ℃; 1263 ℃ ...Computer calculates goes out average value measured, compares with the Heating temperature numerical value that requires, if deviation is arranged again, computer is output signal according to certain rules, deliver to performer, performer drives coal gas adjusting turnover panel and adds and subtracts the coal gas amount, thereby realizes the coke-oven heating-temperature intelligent control.
The thermopair installation site is very important, and the present invention upwards inserts thermopair from the coke oven bottom, is installed near the coal gas burner of flue, can truly reflect coke-oven heating-temperature herein, and the wiring installation easily, avoided high temperature to burn out electric wire.The fire path temperature signal of thermopair collection passes to computer, adopts the computer rule to regulate furnace temperature, makes furnace temperature remain on set-point.The present invention adopts dissimilar coke ovens is surveyed, and understands the furnace temperature Changing Pattern of each coke oven, sets up mathematical model.Because the complicacy of coke oven, interfering factors is many, so the present invention sets up expert experience base to the temperature adjustment of the coke oven of different factories, different areas, the different type of furnaces, adds modern control theory with expert database and realizes intelligent control furnace temperature.
The present invention can realize the intelligent control of coke-oven heating-temperature on different areas, different factory, the different type of furnace, realize closed loop adjustment, through proving in installation test on the coke oven: 1, furnace temperature can control ± 3 ℃ in; 2, saving adds heating gas 3-5%, produces 500000 tons of coke estimations per year by one, and the saving coke-oven gas per hour about 500 cubic metres, is pressed 0.5 yuan of calculating of every cubic metre of coal gas, saves coal gas and is worth about 2,000,000 yuan in 1 year.3, reduce the content of CO in the waste gas.4, furnace temperature is stable, prolongs the coke oven life-span.
