Изобретение относитс к теплотехнике и может быть использовано в энергетической и химической промышленности.The invention relates to heat engineering and can be used in the energy and chemical industries.

Известен теплообменник, содержащий корпус, частично заполненный жидким теплоносителем , с крышкой, на которой закреплено вертикальное газовое сопло, подключенное к источнику газа, и теплообменные поверхности, погруженные в теплоноситель 1 .Known heat exchanger, comprising a housing, partially filled with a heat-transfer fluid, with a lid on which a vertical gas nozzle connected to a gas source is fixed, and heat exchange surfaces immersed in heat-transfer medium 1.

Недостатком данного теплообменника вл етс значительный капельный унос теплоносител газовым потоком.The disadvantage of this heat exchanger is a significant drop of the coolant gas stream.

Цель изобретени - уменьшение капельного уноса теплоносител .The purpose of the invention is to reduce the droplet entrainment of coolant.

Поставленна цель достигаетс тем, что сопло снабжено рубашкой, имеющей патрубок ввода газа и открытый нижний торец, сообщеный с полостью корпуса, на рубашке укреплен криволинейный отражатель, обращенный выпуклостью вверх.The goal is achieved by the fact that the nozzle is equipped with a jacket having a gas inlet and an open bottom end communicating with the housing cavity, and a curved reflector on the jacket is fixed with its bulge upward.

Кроме того, рубашка установлена с возможностью перемещени вдоль сопла.In addition, the jacket is mounted for movement along the nozzle.

На чертеже схематично изображен предлагаемый теплообменник.The drawing schematically shows the proposed heat exchanger.

Теплообменник содержит корпус 1, крышку 2, на которой закреплено вертикальноеThe heat exchanger includes a housing 1, a cover 2, on which is mounted a vertical

газовое сопло 3, теплообменные поверхности 4, рубашку 5, имеющую патрубок 6 ввода газа и открытый нижний торец 7, сообщенный с полостью корпуса 1. Торец 7 может быть также и перфорирован.a gas nozzle 3, heat exchange surfaces 4, a shirt 5 having a gas inlet nozzle 6 and an open bottom end 7 communicated with the cavity of the housing 1. The end face 7 can also be perforated.

На рубашке 5 может быть укреплен криволинейный отражатель 8, обращенный выпуклостью вверх, а сама рубшка 5 может быть установлена на сопле 3 с возможностью перемещени вдоль сопла, при этомOn the jacket 5, a curvilinear reflector 8 can be strengthened, with the convexity facing upwards, and the jacket 5 itself can be mounted on the nozzle 3 with the possibility of moving along the nozzle, while

10 патрубок 6 должен быть выполнен гибким. Теплообменник работает следующим образом .10 nozzle 6 must be made flexible. The heat exchanger operates as follows.

Claims

Through the nozzle 3, gas is supplied to the surface of the coolant. Heat exchange between the gas and the coolant takes place in the hydrodynamic well, which is formed due to the dynamic effect of the gas on the coolant. In the case of supplying a gas with a higher temperature than the coolant, the heat given off by the gas to the coolant is transferred to the heat exchange surfaces 4 through which the cooling agent flows. In the process of introducing a gas jet into the coolant, a large amount of sprays are generated, which are picked up by the gas flow. The gas stream with drops moving upward from the surface of the coolant enters the zone of action of gas jets flowing from the end of the jacket 5. The jets deflect the gas stream in a horizontal plane, which ensures the separation of the droplets. Reflector 8 deflects the entire gas stream with drops obliquely downward. In this case, part of the droplets due to inertial forces is deposited on the reflector and flows down in the form of a film, and the other part, together with the gas stream, hits the surface of the coolant and here the additional droplets are separated from the stream. The purified gas is removed from the heat exchanger through the outlet. The proposed device allows to reduce the droplet entrainment of the coolant from the apparatus and thereby increase its efficiency. Claim 1. Heat exchanger comprising a body partially filled with a heat-transfer fluid, with a lid on which a vertical gas nozzle connected to a gas source and heat transfer surfaces immersed in a heat-transfer fluid are attached, characterized in that, in order to reduce the heat transfer drift, the nozzle equipped with a jacket having a gas inlet and an open bottom end communicated with the body cavity.

2. A heat exchanger according to claim 1, characterized in that a curvilinear reflector is fixed on the jacket, with the convexity facing upwards.

3. A heat exchanger according to claim 1, characterized in that the jacket is mounted for movement along the nozzle. Sources of information accepted. into account during the examination 1. USSR Author's Certificate No. 742691, cl. F 28 C 3/06, 1978.
