Embodiment 1

[0028] A heat exchanger for scrubbing exhaust gas from ships, including: an upper cooling liquid shell 101, a heat exchange shell 102 and a lower cooling liquid shell 103, and also includes: an upper cooling tube fixing plate 104 and a lower cooling tube fixing plate 105, the upper cooling The lower end of the liquid shell 101 is fixedly connected to the upper surface of the upper cooling tube fixing plate 104, the lower surface of the upper cooling tube fixing plate 104 is fixedly connected to the upper end of the heat exchange shell 102, and the lower end of the heat exchange shell 102 is fixedly connected to the upper surface of the lower cooling tube fixing plate 105. The lower surface of the lower cooling tube fixing plate 105 is fixedly connected to the upper end of the lower cooling liquid shell 103, and multiple sets of baffle plates are uniformly fixed and installed inside the heat exchange shell 102, and the edges of the upper cooling tube fixing plate 104 and the lowe...

Embodiment 2

[0033] Embodiment 2: the difference based on Embodiment 1 is;

[0034] The heat exchange self-regulating tube includes: a temperature-sensing moving tube 401, an upper heat-insulating shell 402, a lower temperature-sensing shell 403, an anti-shock sleeve 404 and a pneumatic pipeline 405, and an upper heat-insulating shell 402 is fixedly installed on the upper surface of the upper cooling tube fixing plate 104, The upper end of the temperature-sensing moving tube 401 is movably socketed inside the upper thermal insulation shell 402, and the lower temperature-sensing shell 403 is fixedly installed on the axis of the lower surface of the lower cooling tube fixed plate 105, and the temperature-sensing moving tube 401 is movably socketed inside the lower temperature-sensing shell 403 At the lower end, multiple groups of pneumatic pipes 405 are fixedly installed in the inner wall of the upper heat preservation shell 402. The inlet of the pneumatic pipe 405 is arranged inside the uppe...

Embodiment 3

[0037] Embodiment 3: the difference based on embodiment 1 and 2 is;

[0038] The baffle includes: a baffle fixed ring 201, a drainage plate 202, a drainage groove 203 and a drainage connection ring 204, the baffle fixed ring 201 is fixedly connected to the heat exchange shell 102, and the inner side of the baffle fixed ring 201 is fixedly connected to the drainage connection ring 204 A drainage plate 202 is fixedly mounted on the inner side of the drainage connection ring 204 , and drainage grooves 203 are provided on both sides of the drainage plate 202 .

[0039] The present invention is equipped with a baffle, and when in use, the temperature-sensing moving tube 401 can react in real time to the heat-exchanging material inside the heat-exchanging shell 102, thereby driving the temperature-sensing moving tube 401 to move back and forth, and driving the drainage plate 202 moves back and forth, so as to change the movement of the heat exchange material, and the drainage groove...

Abstract

The invention discloses a heat exchanger for washing ship exhaust gas, and belongs to the field of heat exchangers for ships. The heat exchanger for washing the ship exhaust gas includes an upper cooling liquid outer shell, a heat exchanger outer shell and a lower cooling liquid outer shell, through a heat exchanging self-adjusting pipe, the whole device can be divided into five parts to be advantageously adjusted according to a baffle plate, fine adjustment is conducted on the whole device, efficiencies of a cooling liquid inlet and a cooling liquid outlet and moving condition of materials inthe device can be effectively adjusted through sensitivity of a temperature sensing moving pipe on the temperature, thus the delay effect due to the fact that temperature measuring is not in time isreduced, and fine adjustment can be conducted on the materials in the heat exchanging process.

Description

technical field [0001] The invention relates to the field of ship heat exchangers, in particular to a heat exchanger used for washing ship exhaust gas. Background technique [0002] When the tube-and-tube heat exchanger is in use, it generally monitors the temperature of the inlet and outlet liquid of the material, and then adjusts the flow of the inlet and outlet of the device and the flow of the coolant inlet and outlet, so that the temperature of the material reaches the specified temperature. However, during the use of the heat exchanger, The temperature is not measured in time, and there will be unavoidable delays when regulating its internal flow, which will cause a certain hysteresis when the device is used as a whole. The whole device is divided into five parts for favorable adjustment, fine-tuning the whole device, through the sensitivity of the temperature-sensing moving tube to temperature, it can effectively adjust the efficiency of cooling liquid import and expo...
