Description

Изобретение относится к энергетй-. ке и может быть использовано, например, для получения пара в парильных отделениях бань.The invention relates to energy. ke and can be used, for example, to produce steam in the steam rooms of baths.

Известна нагревательная установка преимущественно для бани, содержащая корпус с колосниковой решеткой, заполненный теплоаккумулирующей насадкой, и вентилятор со всасывающим и напорным патрубками, последний из которых подключен к нижней части корпуса, причем в насадке установлены электронагреватели, а под решеткой водопроводящая труба с выпускными соплами [1].A known heating installation is predominantly for a bath, comprising a housing with a grate, filled with a heat storage nozzle, and a fan with suction and pressure pipes, the last of which is connected to the lower part of the housing, with electric heaters installed in the nozzle, and a water pipe with outlet nozzles under the grill [1 ].

Однако у этой установки низкая эффективность работы вследствие недостаточной сухости получаемого пара.However, this installation has low efficiency due to insufficient dryness of the resulting steam.

Цель изобретения - повышение эффективности путем повышения сухости пара.The purpose of the invention is to increase efficiency by increasing the dryness of the steam.

Указанная цель достигается тем, что всасывающий патрубок вентилятора подключен своим входным концом к полости корпуса в зоне размещения электронагревателей и сообщен с атмосферой. IThis goal is achieved by the fact that the suction pipe of the fan is connected by its inlet end to the cavity of the housing in the area of electric heaters and communicated with the atmosphere. I

На чертеже изображена нагревательная установка. 30The drawing shows a heating installation. thirty

Установка содержит корпус 1 с колосниковой решеткой 2, заполненный теплоаккумулирующей насадкой 3, и 5 вентилятор 4 со всасывающим и напорным патрубками- 5 и 6, причем в насадке 3 установлены электронагреватели 7 в кожухе 8, к полости которого подключен всасывающий патрубок 5, сообщенный через регулирующие заслонки 9 с атмосферой. Под колосниковой решеткой 2 установлена водоподводящая труба 10 с форсунками 11.The installation comprises a housing 1 with a grate 2 filled with a heat accumulating nozzle 3, and 5 a fan 4 with a suction and pressure nozzles 5 and 6, and in the nozzle 3 there are electric heaters 7 in the casing 8, to the cavity of which is connected a suction nozzle 5, communicated through regulating damper 9 with atmosphere. A water supply pipe 10 with nozzles 11 is installed under the grate 2.

При-работе нагревательной установки подается электрическое напряжение 15 на электронагреватели 7 и включается вентиялятор 4 при закрытых регулирую: щих заслонках 9 . При этом воздух поступает из полости корпуса 1 в кожух „ 8, нагревается электронагревателями 2« 7 и через всасывающий патрубок 5 подается вентилятором 4 в напорный патрубок б и вновь в полость корпуса 1, обогревая теплоаккумуяирующую насад^Λ ку 3. Циркулируя по указанному кон25 туру, воздух прогревает теплоаккумулирующую насадку 3 до рабочей температуры, затем через Форсунки 11 подается вода, которая испаряясь, поступает через колосниковую : peine тку 2 в полость корпуса 1. Проходя через слой теплоаккумулирующей насадки 3, пар перегревается и далее поступает в парильное отделение бани. Часть ещё влажного пара засасывается' вместе ,с воздухом в кожух 8 электронагревателей 7 и, перегреваясь, вновь пода- 5 ется в полость корпуса 1. Объем пара, подаваемого потребителю, можно регулировать регулирующими заслонками 9.When the heating system is operating, an electric voltage 15 is supplied to the electric heaters 7 and the fan 4 is turned on with the closed control valves 9. In this case, air enters from the cavity of the housing 1 into the casing “8, is heated by electric heaters 2’ 7, and through the suction pipe 5 is supplied by the fan 4 to the discharge pipe b and again into the cavity of the housing 1, heating the heat-accumulating nozzle ^Λ ku 3. Circulating according to the indicated circuit, the air warms up the heat storage nozzle 3 to operating temperature, then water is injected through the nozzles 11, which evaporates through the grate: peine fabric 2 into the cavity of the housing 1. Passing through the layer of the heat storage nozzle 3, the steam overheats and then stumbles into the steam room of the bath. Part of the still wet steam is sucked in together with air into the casing 8 of the electric heaters 7 and, when overheated, is again fed into the cavity of the housing 1. The volume of steam supplied to the consumer can be regulated by control valves 9.

Использование предлагаемой уста- Ю новки существенно повышает эффективность работы за счет повышения сухости пара без увеличения мощности, потребляемой электронагревателями.Using the proposed installation significantly increases the efficiency by increasing the dryness of steam without increasing the power consumed by electric heaters.

Claims

The invention relates to energy and can be used, for example, to produce steam in steam baths. The known heating installation is predominantly for a bath, comprising a body with a grate, filled with a heat-accumulating nozzle, and a fan with a suction and discharge nozzle, the latter of which is connected to the lower part of the body, with electric heaters installed in the nozzle, and pipe hell under the grate. with exhaust nozzles 1. however, this unit has low efficiency due to insufficient dryness of the steam produced. The purpose of the invention is to increase efficiency by increasing the dryness of steam. This goal is achieved by the fact that the suction nozzle of the fan is connected to the housing cavity in the area where the electrical heaters are located and communicated with the atmosphere. I The drawing shows the heater installation. The installation includes a housing 1 with a grill 2, filled with a heat-retaining nozzle 3, and a fan 4 with suction and discharge nozzles 5 and 6, with electric heaters 7 in the housing 8 installed in the nozzle 3, to the cavity of which the suction nozzle 5 is connected, communicating through regulating flap 9 with atmosphere. Under the grate 2, a virtual pipe 10 with nozzles 11 is installed. When the heating unit is in operation, electrical voltage is applied to the electric heaters 7 and the fan 4 is turned on when closing: the regulating dampers 9. When air flows from the cavity of the housing 1 to the casing B It is heated by electric heaters 7 and through suction vacuum pipe 5 is supplied by fan 4 to discharge port b and again into the body cavity 1 g of heating heat accumulator nozzle 3. Circulating along the indicated circuit, the air heats up the heat accumulator liruyuschuyu nozzle 3 to the working temperature, then through the nozzles 11 water is supplied which is vaporized to, enters through the grate: sous solution 2 in the body cavity 1. Passage through the heat storage layer 3, the nozzle, the steam is superheated and then enters the steam bath department bath. A part of the still wet steam is sucked together with air into the casing 8 of the electric heaters 7 and, overheating, is again supplied to the cavity of the housing 1. The volume of steam supplied to the consumer can be adjusted by adjusting the dampers 9. I Using the proposed installation significantly improves the working efficiency by increasing the dryness steam without increasing the power consumed by electric heaters. Claims. The heating installation of the predominant bath, comprising a case with a grate outlet, filled with a heat-accumulating nozzle, and a fan with suction and pressure nozzles, the last of which is connected to the lower part of the case, has electric heaters in the nozzle, and a water pipe with outlet nozzles installed in the nozzle, so that, in order to increase efficiency by increasing the dryness of steam, the suction inlet of the fan is connected with its inlet end to the body cavity in the area of the electric tro. heaters and communicated with the atmosphere.
