Description

Technical Field

[0001] The invention relates to the technical field of ship heat exchangers, in particular to a ship heat exchanger used for exhaust gas washing. Background Art

[0002] In the global shipping industry, the vast majority of ships use heavy oil as a power fuel. Ship engines and boilers release a large amount of pollutants during the combustion process, especially black smoke and sulfur oxides, which have a serious impact on the environment. Ship scrubbers can effectively reduce sulfur oxide and particulate matter emissions from ship engines, generators and boilers. The treated exhaust gas can be processed by a heat exchanger, which is a device that transfers heat energy in the exhaust gas to other process media through heat exchange.

Improving the heat exchange efficiency means that heat energy can be used more effectively and energy waste can be reduced. In the ship exhaust gas treatment system, this can not only reduce operating costs, but also help reduce carbon emissions, which is in line with the development trend of green shipping. When the heat exchange efficiency is improved, the system will respond more quickly and stably to temperature fluctuations, which helps to reduce system instability that may be caused by temperature regulation lags and improve the reliability and safety of the overall system. Sufficient and uniform heat exchange helps to reduce the risk of equipment damage caused by local overheating or insufficient cooling. In the long run, this will help to extend the service life of the exchange tube 6 and other related components and reduce maintenance costs. ;

[0036] The working principle of the present invention is as follows: hot exhaust gas enters the interior of the heat exchanger body 1 through the intake pipe 4, and under the action of multiple baffles 7, its flow velocity will change, thereby generating eddy currents or turbulence. This turbulence phenomenon helps to increase the contact area between the heat transfer medium and the heat exchange pipe. In this process, the first motor 121 is used to drive the first gear 122 to rotate, and the first gear 122 drives the second gear 123 to rotate, and the third transmission rod 112 can be driven to rotate through the second gear 123 to provide power for the third transmission rod 112. After the third transmission rod 112 rotates on the fixed block 186, the first worm 113 drives the first worm wheel 103 to rotate, and the second worm 114 drives the second worm wheel 104 to rotate, so that the first transmission rod 10 1 and the second transmission rod 102 rotate synchronously. After the first worm gear 103 rotates, the first worm gear 103 drives the first transmission rod 101 to rotate. After the second worm gear 104 rotates, the second worm gear 104 drives the second transmission rod 102 to rotate, so that the first turbulence plates 8 on both sides can be rotated. When the first transmission rod 101 rotates, the first active gear cone 131 drives the first driven gear cone 132 to rotate, and the first driven gear cone 132 drives the first driving shaft 133 to rotate, so that the first driving shaft 133 drives the second turbulence plate 9 to rotate. After the second transmission rod 102 rotates, the second active gear cone 141 drives the second driven gear cone 142 to rotate, and the second driven gear cone 142 drives the second driving shaft 143 to rotate, so that the second driving shaft 143 drives the second turbulence plate 9 to rotate. The baffle plate 9 rotates, which enhances the turbulence effect and greatly improves the turbulence intensity. The increase in turbulence intensity directly promotes full contact and efficient heat exchange between the hot gas and the coolant in the heat exchanger, thereby greatly improving the heat transfer effect. When it is necessary to move the baffle plate 7, the first turbulence plate 8, and the second turbulence plate 9 in the heat exchanger body 1, the second motor 151 drives the first sprocket 152 to rotate, the first sprocket 152 drives the second sprocket 154 to rotate through the chain 153, and the second sprocket 154 drives the screw rod 155 to rotate, providing power for the movement of the baffle plate 7, so that the baffle plate 7 moves horizontally under the action of the guide rod 156, changes the working position, and allows the hot gas to be more fully disturbed and dispersed, which not only significantly improves the turbulence effect of the hot gas, but also It ensures comprehensive and efficient heat exchange between hot air and the inner wall of the heat exchanger and the coolant, and achieves higher heat transfer efficiency and energy utilization efficiency. An installation box 16 is set at the liquid inlet pipe 2 and the air inlet pipe 4. A filter core plate 161 is installed inside the installation box 16. The filter core plate 161 consists of a first filter element 1611 and a second filter element 1612, which can filter the liquid and gas entering the heat exchanger body 1 again. The first filter element 1611 can effectively block tiny particles and impurities and prevent them from entering the exchange tube 6, thereby avoiding the risk of clogging the exchange tube 6 and ensuring the smooth flow of the coolant, which is very important for maintaining the stable operation of the heat exchanger. The second filter element 1612 can capture and remove tiny dust and impurities in the gas.Preventing these impurities from adhering to the outer surface of the exchange tube 6 can not only keep the exchange tube 6 clean, but also ensure that the heat transfer process is not hindered, further improving the efficiency of heat exchange, thereby providing a guarantee for the heat exchange work. Therefore, solving the problem of limited turbulence intensity in the device can not only significantly improve the heat exchange efficiency, optimize energy utilization, enhance system stability, but also effectively extend the life of the equipment. These improvements not only directly improve the performance of the ship exhaust gas treatment system, but also meet the dual goals of environmental protection and economic benefits, which is of great significance to promoting green shipping and sustainable development.
