(54) СИСТЕМА ТЕПЛОСНАБЖЕНИЯ ПРОМЫШЛЕННОГО ПРЕДПРИЯТИЯ ОТ ЦЕНТРАЛЬНОЙ КОТЕЛЬНОЙ(54) HEAT SUPPLY SYSTEM OF INDUSTRIAL ENTERPRISE FROM THE CENTRAL BOILER ROOM

II

Изобретение относитс к области теплоснабжени и может быть использовано на хлебозаводах имеющих в качестве источника тепла паровые котлы.The invention relates to the field of heat supply and can be used in bakeries having steam boilers as a heat source.

Известна система теплоснабжени , содержаща паровой котел, паропроводы, конденсаторы , редуктор, охладитель пара, конт денсатоотводчики, паровые змеевики, выходы которых соединены с конденсатоотводчиками 1.A heat supply system is known, comprising a steam boiler, steam lines, condensers, a gearbox, a steam cooler, a steam trap, steam coils, the outlets of which are connected to condensate drains 1.

Недостатком известной системы вл етс то, что температура греющих змеевиков теплоприемников вл етс заданной и посто нной , что исключает в случае необходимости ее изменени .A disadvantage of the known system is that the temperature of the heating coils of the heat sinks is fixed and constant, which excludes, if necessary, its change.

Целью изобретени вл етс обеспечение повыщени температуры паровых змеевиков .The aim of the invention is to provide an increase in the temperature of the steam coils.

Цель достигаетс тем, что в системе теплоснабжени промыщленного предпри ти от центральной котельной, содержащей паровой котел, паропровод|)1, конденсатопроводы , редуктор, охладитель пара, конденсатоотводчики , паровые змеевики, выходы котО рых соединены с конденсатоотводчиками,, а также дополнительно соединены с паропроводом между редуктором и охладителем пара.The goal is achieved by the fact that in the heat supply system of an industrial enterprise from a central boiler house containing a steam boiler, a steam line, the condensate lines, a reducer, a steam cooler, steam traps, steam coils, outlets that are connected to steam traps, and are additionally connected to the steam line between the gearbox and the steam cooler.

На чертеже изображена предлагаема система теплоснабжени .The drawing shows the proposed heat supply system.

Она содержит паровой котел 1 с параметрами преимущественно 40ата при 440°С, редуктор 2, соединенный паропроводом 3 острого пара с котлом 1,охладитель 4 пара, соединенный паропроводом 5 редуцированного пара с редуктором 2, коллектор 6 редуци - рованного пара, соединенный паропроводом 7 с охладителем 4 пара и паропроводом 8 с заводскими потребител ми 9 тепла. Последние конденсатопроводом 10 с включенным в него насосом 11 соединены с паровым котлом 1. Система также содержит греющиеIt contains a steam boiler 1 with parameters mainly 40ata at 440 ° С, a reducer 2 connected by a steam pipe 3 to hot steam with a boiler 1, a steam cooler 4 connected by a steam pipe 5 reduced steam to a gear 2, a collector 6 reduced steam 7 seconds 4 steam chiller and steam pipe 8 with factory users 9 heat. The latter condensate line 10 with the pump 11 included in it is connected to the steam boiler 1. The system also contains heating

Claims

15 steam coils 12, the entrances of which with steam lines 13 with valves 14 connected to them are connected to steam pipe 3 3, and their outlets by pipes 15 with steam traps 16 included in them are connected to condensate line 10. The outputs of coils 12 besides pipes 17 from those included in them the valves 18 bypassing the steam trap 16 are connected to a steam reduced steam pipe 5 connecting the gearbox 2 with a steam cooler 4. The system works as follows. Steam boiler 1 is supplied via steam line 3 to steam reducer 2 and heating coils 12. In gearbox 2, the vapor pressure decreases and the latter is supplied to steam cooler 4 through steam conduit 5 and then through steam conduit 7, collector 6 and steam lines 8 to factory consumer m 9 heat. At consumer 9, steam is condensed, giving off heat, for example, for heating, ventilation and hot water supply, and condensate is fed through condensate line 10 by pump 11 to steam boiler 1. From steam line 3, steam is fed through steam lines 13 through valves 14 to heat steam coils 12. In the latter, steam condenses, giving off heat to condensation. The resulting condensate from the coils 12 through the trap 16 through pipelines 15 leads to the condensate line 10 of the heat supply system. If it is necessary to raise the temperature of the steam coils, one or several valves 18 are opened and the coils are heated by the transit steam entering the steam line 5, through which steam is subsequently fed to the cooler 4 and then to the users 9 for further use. Due to the increase in the temperature of the heating coils due to the additional connection of their outputs to the steam pipe between the gearboxes and the steam cooler, heat will be more fully utilized by the heat consumer. Claims The heat supply system of an industrial enterprise from a central boiler house, comprising a steam boiler, steam lines, condensate lines, gearbox, steam cooler, steam traps, steam coils, whose outlets are connected to steam traps, is characterized in that, in order to increase the temperature range of steam coppers, they are designed to increase the temperature of the steam traps, in order to increase the temperature of the steam traps, in order to increase the temperature of the steam traps. the latter are additionally connected to the steam line between the gearbox and the steam cooler.
