Podstata vynálezu spočívá v tom, že pri paralelnom spojení dvoch tepelných médií — páry a odpadové teplot vratného kondenzu z iných technologických zariadení je automaticky vždy přednostně využívané odpadové teplo vratného kondenzu a taktiež automaticky regulované v rozsahu predpísanej teploty ohrievanej látky. Tepelné médium — para je taktiež automaticky využívané len v tom případe, ak nie je dostatok odpadového tepla vratného kondenzu. Navýše ohřev látok je časové riadený a automaticky odstavovaný přívod tepelnej energie, keď nie je ohřev žiadúci. Jeho využitie je možné uplatnit vo všetkých odvetviach národného hospodárstva, kde sa používá k ohřevu látok tepelné médium — paraThe invention relates to the field of thermal engineering of rational use of thermal energy and solves the problem of economical regulation of heating of substances in a closed space, for which the prescribed heating temperature is lower than the temperature of the waste heat of the return condensate. The essence of the invention lies in the fact that when two thermal media are connected in parallel — steam and waste heat of the return condensate from other technological devices, the waste heat of the return condensate is automatically always used preferentially and is also automatically regulated within the prescribed temperature range of the heated substance. The thermal medium — steam is also automatically used only in the case when there is not enough waste heat of the return condensate. In addition, the heating of substances is a time-controlled and automatically shut-off supply of thermal energy when heating is not desired. Its use can be applied in all sectors of the national economy, where the thermal medium — steam is used to heat substances

Vynález rieši zariadenie pre racionálny automatický ohřev látok *ν .yuzatvorenpns priestore v paralelnom spojení tdvoch tepel- ných médií. i ".·-· · .. --The invention provides a device for rational automatic heating of substances in a space in parallel connection of two thermal media. i ". · - · · .. -

Doteraz je ohřev látok &>" uzatvorenompriestore prevádzaný použitím jedného te-pelného média — páry, ktoré odovzdávasvoju teplotu prostredníctvom ohrievača o-hrievaným látkám.Up to now, heating of substances & " is closed by using one heat medium - vapor, which passes temperature through the heater.

Tento- sposob ohřevu má tieto nevýhody:This heating method has the following disadvantages:

Ohřev látok v uzatvorenom priestore jeprevádzaný cenovo nákladným tepelnýmmédiom — parou aj u látok, u ktorých jepožadovaná teplota nižšia ako je odpadováteplota tepelného média páry, a to aj v ča-se, keď to nie je potřebné, čo sposo-buje zby-tečné straty tepelnej energie.The heating of the substances in the enclosed space is accompanied by cost-effective thermal steam - even for substances in which the required temperature is lower than that of the thermal medium of the steam, even in time when this is not necessary, which results in unnecessary heat loss. energy.

Podstata vynálezu spočívá v tom, že za-riadenie pre racionálny automatický ohřevlátok v uzatvorenom priestore je tvořenéprívodným potrubím páry a prívodným po-trubím kondenzátu, ktoré sú paralelné při-vedené do ohrievača v uzatvorenom priesto-re cez prietokový ventil páry a trojcestnýventil kondenzátu so servomotormi, ktorésú riadené rozlišovacím obvodom, kontakt-ným teplomerom a časovým spínačom. Narozlišovací obvod je připojený snímač kon-denzu. Výhoda tohto riešenia spočívá v tom, žeohřev látok v uzatvorenom priestore je au-tomaticky riadený v celom rozsahu a naohřev je přednostně automaticky využívanéodpadové teplo kondenzátu z iných techno-logických zariadení a súčasne je odstavo-vané energeticky náročné tepelné médium— para, ktoré je taktiež automaticky vy-užívané iba v tom případe, ak nie je dosta-tečné množstvo a teplota odpadového teplakondenzátu. Týmto sposobom sa šetří pri-márná tepelná energia — para a súčasne jevyužitý tepelný spád odpadového tepla kon-denzátu z iných technologických zariade-ní.The essence of the invention is that the device for rational automatic heating in the enclosed space is formed by the inlet steam conduit and the condensate inlet pipes, which are parallel fed into the heater in a closed place via a steam flow valve and three-way condensate valve with servomotors controlled by the resolution circuit, the contact thermometer and the timer. The differentiation circuit is connected to the con- densor. The advantage of this solution is that the heating of the substances in the enclosed space is automatically controlled in its entirety and the heating is preferably automatically utilized by the waste heat of the condensate from other technological equipment and at the same time the energy-intensive thermal medium - steam, which is also automatically used only if the amount and temperature of the waste heat condensate is not sufficient. In this way, the primary thermal energy - steam is saved and at the same time the thermal drop of the condensate waste heat from other technological equipment is utilized.

Na pripojenom výkrese je znázorněné za-riadenie pre racionálny automatický sy-stém ohřevu látok v uzatvorenom priestore,ktorých požadovaná teplota je nižšia akoje teplota odpadového tepla vratného kon-denzu.In the accompanying drawing, there is shown a device for rational automatic heating of substances in a closed space, the desired temperature of which is lower than the return temperature of the return condenser.

Do ohrievača 15 v uzatvorenom priestore16 ohřevu látok je privádzané prívodnýmpotrubím 11 tepelné médium — para a prí-vodným potrubím 12 tepelné médium — vrat-ný kondenz.Heat medium 11 is supplied to the heater 15 in a closed material heating space 16 by means of an inlet pipe 11 - a heat medium - a return condenser.

Servomotor 7 reguluje tepelné médium —páru pomocou prietokového ventilu 8 pá- ry a servomotor 9 mění směr prúdenia vrat-ného kondenzp .pemocou trojcestného ven-tilu 10 kondenzu. Servorrfotory 7 a 9 sú ria-děné1'-rozliš ovacím obvodom 5, ktorý vždyriádí iba jeďéh servomotor v závislosti nanastavenej teplote a u druhého servomotoradrží zatvorený přívod druhého tepelnéhomédia. Rozlišovací obvod 5 je riadený sní-mačom 6 kondenzu. Ak sa v prívodnom po-trubí 12 objaví vratný kondenz požadova-nej teploty, dá snímač 6 kondenzu povelrozlišovaciemu obvodu 5, ktorý přednostnězapojí servomotor 9 a tento automatickyreguluje trojcestný ventil 10 kondenzu vzávislosti na teplote ohrievanej látky vpriestore 16 ohřevu látok. Kondenz je pri-vádzaný prívodným potrubím 12 cez troj-cestný ventil 10 do ohrievača 15. Keď do-siahne ohrievaná látka v uzatvorenompriestore 16 ohřevu látok požadovanú tep-lotu, dá kontaktný teploměr 1 povel po-mocnému relé 4, ktoré cez rozlišovací ob-vod 5 riadi servomotor 9.The servomotor 7 regulates the heat medium — a steam by means of a flow valve 8 of steam and the servomotor 9 changes the direction of flow of the return condenser by the three-way condenser valve 10. The servo motors 7 and 9 are controlled by a differentiating circuit 5 which only supplies the servomotor in dependence on the set temperature and the second servomotor holds the second heat medium closed. Resolution circuit 5 is controlled by condenser 6. If a return condenser of the desired temperature appears in the supply pipe 12, the sensor 6 will give a condensation-sensitive circuit 5 which preferably connects the servomotor 9 and this automatically regulates the three-way valve 10 depending on the temperature of the heated material in the space heating chamber 16. The condensate is fed through the inlet pipe 12 via a three-way valve 10 to the heater 15. When the heated substance reaches the desired temperature in the closed substance heating chamber 16, the contact thermometer 1 commands the auxiliary relay 4 which, through the resolution sensor Water 5 controls the servomotor 9.

Servomotor 9 změní směr prúdenia kon-denzu pomocou trojcestného ventilu 10 akondenz je odvádzaný cez obtokové potru-bie 13 do odpadového potrubia 14. Pri po-klese teploty ohrievanej látky v uzatvore-nom priestore 16 kontaktný teploměr 1 dápovel pomocnému relé 4, ktoré cez rozlišo-vací obvod 5 zapojí servomotor 9. Servo-motor 9 pomocou trojcestného- ventilu 10změní směr prúdenia kondenzu do ohrie-vača 15, prostredníctvom ktorého odovzdá-va svoju teplotu ohrievanej látke v uzatvo-renom priestore 16 ohřevu látok.The servomotor 9 changes the direction of flow of the condensation by means of a three-way valve 10 and is discharged via the bypass pipe 13 to the waste pipe 14. When the temperature of the heated substance decreases in the closed space 16, the contact thermometer 1 grinds the auxiliary relay 4, which via a different The servo motor 9, by means of a three-way valve 10, changes the direction of the condensation flow into the heater 15 by means of which it passes its temperature to the heated substance in the closed space 16 of heating the substances.
