Description

(54) КОЛЛЕКТОР ТЕПЛООБМЕННИКА(54) HEAT EXCHANGER COLLECTOR

, ,

Изобретение относитс к энергетике и может быть использовано в пароперегревател х котлов.The invention relates to energy and can be used in steam superheaters of boilers.

Известен коллектор теплообменника, содержащий корпус с отверсти ми в его боковой стенке и торцовым патрубком, а также распределительный элемент, установленный в корпусе с возможностью продольного перемещени и имеющий ко1Шческую форму дл изменени проходного сечени корпуса 1 . A heat exchanger collector is known, comprising a housing with openings in its side wall and an end pipe, as well as a distribution element installed in the housing with the possibility of longitudinal movement and having a coil shape for changing the flow area of the housing 1.

Недостатком такого коллектора теплообменника вл етс сложность конструкции, обусловленна наличием распределительного злемента.The disadvantage of such a heat exchanger collector is the complexity of the design, due to the presence of the distribution element.

Наиболее б}шзким к предлагаемому вл етс коллектор теплообменника, содержащий корпус с отверсти ми в его боковой стенке и торцовый патрубок, продольно установленный в корпусе с образованием кольцевого зазора 2.Most promising is a heat exchanger manifold comprising a housing with openings in its side wall and an end fitting longitudinally mounted in the housing to form an annular gap 2.

Недостатком такого коллектора теплообменника вл етс пониженна надежность теплообменника при работе его на переменных режимах, так как неподвижный торцр2The disadvantage of such a collector of the heat exchanger is the reduced reliability of the heat exchanger when operating in variable conditions, since the fixed facer 2

вый патрубок установлен в Kojmyce, исход из конкретной тепловой нагрузки тешюобмениика , что может привести к значительной теплогидравлической разверке в последнем и его повреждению. . ч Целью изобретени вл етс ровыщение надежности теплообменника при работе его на переменных режимах.The new nozzle is installed in Kojmyce, based on the specific heat load of the pump, which can lead to a significant thermal-hydraulic sweep in the latter and its damage. . The aim of the invention is to improve the reliability of the heat exchanger when operating in variable conditions.

Указанна цель достигаетс тем, что торцовый патрубок установлен в корпусе с возмож10 ностью продольного перемещениеНа фиг. 1 схематически изображен коллектор теплообменника, общий вид; иа фиг. 2 - разрез А-А на фиг. 1.This goal is achieved by the fact that the end fitting is installed in the housing with the possibility of longitudinal displacement. In FIG. 1 shows schematically the collector of the heat exchanger, general view; FIG. 2 shows section A-A in FIG. one.

Патрубок 3 установлен в отйер-, The collector bag of the bag contains a housing 1 with holes 2 in its Icon wall and an end socket 3 longitudinally mounted in the housing 1 to form an annular gap 4 and with the possibility of longitudinal movement. Nozzle 3 is installed in the outlet,

Claims

The described device can be used as a dispenser as well as a collecting collector of a superheater boiler. The heat exchanger collector operates as follows. If the heat exchanger collector is used as a distributing collector, the working medium is fed into the housing 1 through nozzle 3. Then it is directed to the annular gap 4, and from the latter to the openings 2. If the heat exchanger collector is used as a collecting collector , working medium; skip, pieces in the opposite direction. uocise starts the heat exchanger (boiler) is brought to the specified operating mode. Then the installation bolt 7 is released and the nozzle 3 with the washer 5 is moved to one or another, thereby changing Revealing the annular gap 4 until the temperature deviation of the steam at the exit from the parser superheater from the middle (according to the indications of the corresponding sensors) reaches the minimum possible value. After this P, the pipes 3 fix it to the Cai 6 5 by means of the bolt 7. When changing the boiler operation mode, the adjustment operation f 3 9 4 of the superheater temperature by moving the nozzle 3 is repeated. The proposed device of the heat exchanger collector eliminates in the latter: a heat-hydraulic sweep and increase it about reliability. Claims of the heat exchanger, comprising a housing with openings in its side wall And then a hydraulic pipe longitudinally mounted in the housing to form an annular gap, characterized in that, in order to increase the reliability of the heat exchanger when operating on variable modes, the end fitting is installed in the housing with the possibility of longitudinal movement.
