Description
Vynález se týká regulačného ústrojí kruhových pecí pre výpal keramického tovaru najmá v priemysle hruběj keramiky.BACKGROUND OF THE INVENTION 1. Field of the Invention The invention relates to a regulating device for circular furnaces for firing ceramic goods, particularly in the thicker ceramic industry.
Doteraz známe kruhové pece majú dvojstupňová reguláciu teploty v páliacom pásme. Ďalšia veličina tj. meranie podtlaku v predhrievacom pásme je iba sledovaná a je bez návaznosti na automatická reguláciu. Termočlánky sú osadené iba v páliacom pásme a sú premiestňované v závislosti od postupu ohňa spolu s horákmi.The known circular furnaces have two-stage temperature control in the firing zone. Another quantity, ie. vacuum measurement in the pre-heating zone is only monitored and is not linked to automatic regulation. The thermocouples are mounted only in the firing zone and are displaced depending on the fire progression along with the burners.
Vyvážka tovaru do značnej miery ovplyvňuje vzduchotechnické poměry i v samotnom chladiacom a paliacom pásme a to nekotrolovaným množstvom přívodu studeného vzduchu. Množstvo a teplota pri odtahu teplého vzduchu z chladnúceho pásma do sušiarne je závislé iba od ludského činitela a preto v konečnom dósledku nehospodárne. Dýmové plyny odtahované do komína sú kontrolované iba teplomerom. Je to bez návSznosti na zníženie komínových strát znížením ich teploty, iThe export of goods influences air-conditioning conditions to a great extent also in the cooling and burning zone itself by the unchecked amount of cold air supply. The amount and temperature of the exhaust of the warm air from the cooling zone to the dryer is dependent only on the human agent and therefore ultimately uneconomical. The flue gases drawn into the chimney are controlled only by a thermometer. This is not related to reducing the chimney losses by lowering their temperature, i
množstva alebo dokonalejšieho využitia paliva spalovaného v horákoch resp. zalisovaného do suroviny.the amount or better utilization of the fuel burned in the burners respectively. pressed into the raw material.
Uvedené nevýhody sú odstránené regulačným ústrojím podlá vynálezu, kde podstata spočívá v tom, že pásmo rýchlochladenia pece je vybavené mobilnými chladiacimi agregátmi. Chladiace pásmo pece je vybavené mobilnými prepojovačmi vzduchu, pričom v pravidelných vzdialenostiach po peci sú rozmiestnené stabilné termočlánky pre meranie teploty. Za páliacim pásmom pece je umiestnený přenosný manovakuometer pre meranie tlaku vzdušin v peci a před páliacim pásmom je umiestnený druhý přenosný manovakuometer, ktoré sú napojené na riadiaci systém.These disadvantages are overcome by the control device according to the invention, wherein the essence is that the furnace quick-cooling zone is equipped with mobile cooling units. The cooling zone of the furnace is equipped with mobile air couplers and stable thermocouples are placed at regular intervals around the furnace for temperature measurement. A portable mano-vacuum gauge for measuring the air pressure in the furnace is placed downstream of the firing zone of the furnace, and a second portable mano-vacuum gauge, which is connected to the control system, is located upstream of the firing zone.
Riadiaci systém v súlade podlá predpísanej páliacej křivky dodržuje pomocou akčných členov žiadanú teplotu v páliacom pásme a dalej zvukovými alebo světelnými signálmi označuje pracovný úkon, ktorý je potřebný z hladiska hospodárnej technológie výroby. Jedná sa o účelnú manipuláciu s horákovými súpravami, mobilných chladiacich agregátov, mobilných prepojovačov vzduchu ako i priamočiarych posúvačov dýmových plynov po peci v závislosti od rýchlosti postupu ohňa.The control system, in accordance with the prescribed firing curve, maintains the required temperature in the firing zone by means of actuators and further indicates by means of acoustic or light signals the operation which is necessary in terms of economical production technology. It is a purposeful handling of burner kits, mobile cooling units, mobile air couplers as well as straightforward flue gas scavengers in the furnace depending on the speed of the fire.
Znížením vplyvu ludského činitela pri výpale keramického tovaru na kruhových peciach a rozšířením pracovných zásahov i do chladiaceho a predhrievaceho pásma podlá stanoveného optimálneho programu dosiahnú sa kvalitativně vyššie podmienky pre zaistenie dobrej akosti keramických výrobkov a vysokej hospodárnosti pri znížení mernej spotřeby paliva.By reducing the influence of the human factor in the firing of ceramic goods in circular furnaces and by extending the work interventions to the cooling and preheating zone according to the set optimal program, qualitatively higher conditions will be achieved to ensure good quality of ceramic products and high economy while reducing specific fuel consumption.
Příklad využitia regulačných ústrojí kruhovej pece podlá vynálezu je zobrazený na výkrese.An example of the use of the control apparatus of a circular furnace according to the invention is shown in the drawing.
Na kruhovej peci 1 sú v páliacom pásme horákové súpravy 2, v pásme rýchlochladenia mobilně chladiace agregáty 2 a v chladiacom prásme mobilně přepojovače 4 vzduchu. Pec je vybavená tiež stabilnými termočlánkami umiestnenými v pravidelných vzdialenostiach v telese pece. Na meranie teploty dýmových plynov slúži termočlánok 2 dýmových plynov. Meranie tahu - tlaku v pecnom priestore zaobstarávajú manovakuometre a to přenosný manovakuometer.On the annular furnace 1, in the firing zone, there are burner sets 2, in the rapid cooling zone, mobile cooling units 2 , and in the cooling zone, mobile air switches 4. The furnace is also equipped with stable thermocouples placed at regular distances in the furnace body. The flue gas thermocouple 2 is used to measure the flue gas temperature. Measurement of thrust - pressure in the furnace space is provided by manometers - portable manometers.
za páliacim pásmom a druhý přenosný manovakuometer jJ umiestnený před páliacim pásmom.downstream of the firing zone and a second portable manometer vacuum located 11 upstream of the firing zone.
Dýmové plyny z pece odtahuje ventilátor 2 dýmových plýnov. Teplý vzduch do sušiarne odtahuje teplovzduŠný ventilátor 10. Intenzitu prúdenia dýmových plynov reguluje regulačný orgán 11 dýmových plynov a teplého vzduchu regulačný orgán 12.The flue gases from the furnace are drawn off by the fan 2 of the flue gases. Warm air is drawn into the dryer by the air fan 10. The flue gas flow rate is regulated by the flue gas regulator 11 and the hot air regulator 12.
Teplotu teplého vzduchu do sušiarne merá termočlánok 13 a tlak tlakoměr 14. Dóležitú funkciu pri regulácii jednotlivých sledovaných veličin má riadiaci systém _1_5♦ Teplý vzduch z kruhovej pece je využívaný v sušiarni 26. V dýmovode do komína 18 je zabudovaný analyzátor 17 dýmových plynov. Dlžka a intenzita predhrevu v predhrievacom pásme je určovaná otváraním a zatváraním dýmových kanálov 20 priamočarými posúvačmi 19.The temperature of the hot air to the dryer is measured by the thermocouple 13 and the pressure by the pressure gauge 14. The control system 15 has an important function in the control of the individual quantities being monitored. The warm air from the circular furnace is used in the dryer 26. The length and intensity of preheating in the preheating zone is determined by the opening and closing of the smoke channels 20 by the linear sliders 19.
Činnost zariadenia je nasledovná. Meraním teploty v páliacom pásme stabilnými termočlánkami 5 zistí sa odchýlka od predpísanej páliacej křivky. Riadiaci systém 15 ak je vybavený regulátormi pri vyššej teplote v peci ako predpísanej přepne ovládanie horákovej súpravy na udržiavací příkon, ktorý je nižší ako prevádzkový příkon.The operation of the device is as follows. By measuring the temperature in the firing zone with stable thermocouples 5, a deviation from the prescribed firing curve is detected. The control system 15, if equipped with controllers at a higher oven temperature than prescribed, switches the burner set control to a maintenance power that is lower than the operating power.
Regulácia je teda dovojpolohová. Pri vybavení riadiaceho systému 15 mikropočítačovou technikou, tepelný příkon horákových stíprav sa mění plynule. Meraním tahu před a za páliacim pásmom zistí sa tlaková diferencia. Potřebné diferenciu tlakov sleduje podlá nastavenej hodnoty riadiaci systém 15 a to zásahom na regulačný orgán 11 dýmových plynov. Regulačný orgán 12 teplého vzduchu je ovládaný v závislosti od tlakoměru 14.The regulation is therefore in the position. When the control system 15 is equipped with microcomputer technology, the thermal input of the burner strips varies continuously. By measuring the thrust upstream and downstream of the firing zone, the differential pressure is determined. The necessary pressure differential is monitored by the control system 15 according to the set value by the intervention of the flue gas regulating body 11. The hot air regulating element 12 is controlled depending on the pressure gauge 14.
V závislosti od termočlánku 13 teplého vzduchu je dávaný riadiacím systémom 15 signál pre premiestňovanie mobilných prepojovačov 4 vzduchu a od termočlánku 6 dýmových plynov a analyzátore 17 otváranie a zatváranie priamočiarych posúvačov 19 v predhrievacom pásme pece.Depending on the warm air thermocouple 13, the control system 15 provides a signal for moving the mobile air couplers 4, and from the flue gas thermocouple 6 and the analyzer 17 to open and close the rectilinear sliders 19 in the preheating zone of the furnace.
Výhody takéhoto vyhotovenia pri pálení keramického materiálu v kruhových peciach sú v dodržaní páliacej křivky v celom rozsahu, čo má dopad na zlepšenie kvality tovaru a zníženie mernej spotřeby paliva.The advantages of such an embodiment when firing ceramic material in circular furnaces are in keeping the firing curve in its entirety, which has the effect of improving the quality of the goods and reducing the specific fuel consumption.
Vynález je možno využit v priemysle hruběj keramiky.The invention can be used in the thicker ceramic industry.
