Description

Technical Field

[0001] The present application relates to the field of marine exhaust gas treatment, and in particular to a vertical I-type marine desulfurization scrubber with energy-saving effect. Background Art

[0002] Exhaust gas desulfurization equipment has been put into practical engineering application for decades, with a wide variety of treatment methods and mature technologies. In recent years, ship exhaust gas treatment technology has also received widespread attention. After the ship is equipped with an exhaust gas desulfurization device, the shipowner does not need to modify the engine and fuel supply system and can continue to use cheap heavy fuel oil that matches the main engine performance. The advantage of this is that it avoids the various ship operation risks brought about by the replacement of low-sulfur oil and the huge modification costs of using natural gas as an alternative fuel. At the same time, it can save shipowners a lot of fuel costs.

[0003] In view of the current environmental protection regulations and in order to accelerate the transformation and upgrading of shipbuilding companies, through in-depth research on domestic and foreign markets, a Type I desulfurization scrubber is installed in the exhaust system. When used on self-unloading ships, the ship can burn heavy fuel oil (3.5% m / m sulfur content) during normal navigation and reduce sulfur emissions to the same level as burning low-sulfur oil with a sulfur content of 0.10% m / m, so as to achieve the purpose of removing sulfur emissions. Therefore, the improvement of desulfurization scrubbers for ships is of great significance.

[0004] In the prior art, in order to improve the contact between the desulfurization reagent and the exhaust gas, a related mixing structure is usually set in the desulfurization washing tower for ships to improve its desulfurization effect. The setting of the mixing structure brings about the use of electric energy by its driving structure, which causes the desulfurization washing tower to lose a lot of energy during use and occupy the relatively limited energy on the ship.

[0017] Compared with the existing technology, the advantages of this application are:

[0018] (1) Two upper and lower atomizing desulfurization chambers and a spray desulfurization chamber are provided inside the tower body, and a spray hole is opened on the spray pipe inside the spray desulfurization chamber to spray a large flow of desulfurization reagent. An atomizing nozzle is provided on the atomizing pipe inside the atomizing desulfurization chamber to spray the desulfurization reagent in an atomized manner. One coarse and one fine, two different desulfurization methods are carried out continuously, which is conducive to making the flue gas in the spray desulfurization chamber and the atomizing desulfurization chamber more fully and comprehensively contact with the desulfurization reagent, and to a certain extent improves the removal effect of the device on sulfur emissions in the flue gas. The desulfurization reagent and the flue gas can be fully mixed without the help of other mixing structures, so there is no need to use energy to drive the mixing structure, which to a certain extent improves the energy-saving effect of the device.

[0019] (2) By installing the fan in the middle position of the flue gas transfer interface, auxiliary transportation can be provided for the flue gas inside the flue gas transfer interface, which can improve the smoothness and efficiency of the flue gas entering the secondary desulfurization chamber inside the atomizing desulfurization chamber to a certain extent. At the same time, the fan and the flue gas transfer interface can be installed by connecting them with flanges and bolts, which is conducive to the convenient disassembly of the fan and improves the maintenance convenience of the device to a certain extent.

[0020] (3) By setting the outer shape of the filter plate to an arc-shaped structure and setting the corresponding edge positions on both sides to one side higher and the other side lower, the upper surface of the filter plate forms an arc-shaped inclined guiding structure, which is beneficial to improving its guiding effect on filtering impurities above and ensuring that the filtered impurities are discharged smoothly through the filter plate.

[0021] (4) By rotating the adapter sleeve and sleeved on the outside of the liquid supply pipe, and distributing multiple adapter sleeves around the outside of the adapter sleeve, with the help of the adapter sleeve, multiple adapter sleeves of Shudie can rotate around the liquid supply pipe, thereby improving the comprehensive coverage of the desulfurization reagent spraying inside the spray desulfurization bin. At the same time, by opening the spray hole in the counterclockwise direction of the outer end wall of the spray pipe and setting its opening to a downward inclined structure, when the desulfurization reagent is sprayed out from the spray hole at high speed, the reverse thrust of the fluid during the spraying can provide impetus for the rotation of the adapter sleeve and the spray pipe without the need for an additional driving device, which is beneficial to improving the energy saving effect of the device.

[0022] (5) By setting the shape of the atomizing tube to a vertical spring structure and setting it directly behind the connection point between the flue gas transfer interface and the atomizing desulfurization chamber, when the flue gas is sprayed from the flue gas transfer interface into the atomizing desulfurization chamber, it can directly collide head-on with the atomized desulfurization reagent sprayed from the atomizing nozzle, thereby improving the comprehensiveness of the secondary desulfurization of the flue gas entering the atomizing desulfurization chamber.

[0023] (6) By setting the atomizing tube to rotate and cooperating with the atomizing nozzle to spray the desulfurization reagent, the atomized desulfurization reagent can be more fully and comprehensively filled in the interior of the atomizing desulfurization bin, thereby improving the comprehensiveness of the secondary desulfurization of the flue gas in the atomizing desulfurization bin. By arranging the movably sleeve of the pipe on the outside of the shaft pipe connected to the interior of the atomizing tube, the stability of the desulfurization reagent supply can be guaranteed during the rotation of the atomizing tube.

[0024] (7) By placing the ball inside the atomizing desulfurization chamber, the ball is driven to roll freely inside the atomizing desulfurization chamber with the help of the shaking of the ship during its travel. With the help of the connection of the cable, the valve block is driven to move inside the hydraulic chamber. In conjunction with the oil inlet pipe and the oil outlet pipe and the restriction of the internal one-way valve, the circulation drive of the hydraulic oil inside the annular pipe a is realized, and then the turbofan inside the volute is driven to rotate by the flow of hydraulic oil, providing power for the rotation of the atomizing pipe. The active drive of the atomizing pipe can be completed without providing additional energy-consuming drive parts for the device, which is beneficial to energy saving.

[0025] (8) By movably sleeved the ring on the outside of the ball, and using the ring as a transition medium between the cable and the ball, the ball is prevented from being entangled by the cable during its movement inside the atomizing desulfurization chamber, and to a certain extent, the strength of the ball rolling during the shaking of the ship is improved, which is conducive to providing more stable power for driving the hydraulic oil of the device.

[0026] (9) By providing a guide wheel to guide the bending position of the cable, wear at the through position corresponding to the inside of the atomizing desulfurization chamber during the up and down pulling of the cable can be avoided, thereby helping to increase the service life of the cable.

[0027] (10) A spring is provided to be fixedly connected between the valve block and the bottom inner end wall of the hydraulic chamber, so that when the valve block is pulled upward by the cable, the spring is stretched synchronously. When the cable is relaxed, the spring rebounds and resets, which can provide a stable driving force for the valve block to move downward, which is beneficial to ensure the stable downward reset of the valve block and to a certain extent ensure the working stability of the device.

Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0041] Example 1:

[0042] This application discloses a vertical I-type desulfurization scrubber for ships with energy-saving effect, please refer to Figure 1 - Figure 10 , including a tower body 1, a partition 101 is fixedly installed at the middle position of the interior of the tower body 1, and the interior of the tower body 1 is divided into a spray desulfurization chamber 102 located at the bottom and an atomization desulfurization chamber 103 located at the top by the partition 101. A flue gas inlet 104 is fixedly connected to the middle position of the outer end wall of the spray desulfurization chamber 102, and a flue gas transfer interface 105 arranged on the outside of the tower body 1 is fixedly connected to the top of the spray desulfurization chamber 102 and the middle position of the side end wall of the atomization desulfurization chamber 103. An exhaust port 106 connected to the interior of the atomizing desulfurization bin 103 is fixedly installed at the middle position, and filter plates 107 for filtering are fixedly installed on the lower inner end walls of the spray desulfurization bin 102 and the atomizing desulfurization bin 103. A slag discharge port 108 flush with the filter plate 107 is provided on the side end walls of the spray desulfurization bin 102 and the atomizing desulfurization bin 103, and a liquid discharge port 109 is provided on the side end walls of the spray desulfurization bin 102 and the atomizing desulfurization bin 103, respectively located below the two filter plates 107;

[0043] A vertically arranged liquid supply pipe 2 is fixedly installed at the upper middle position inside the spray desulfurization chamber 102, and a plurality of spray pipes 202 are connected around the outside of the liquid supply pipe 2. A plurality of spray holes 203 are provided on the outer end wall of each spray pipe 202. An atomizing pipe 3 is installed at the middle position inside the atomizing desulfurization chamber 103, and a plurality of spray holes 203 are also evenly provided on the outer end wall of the atomizing pipe 3. An atomizing nozzle 301 is fixedly installed inside the spray hole 203 provided on the atomizing pipe 3. The liquid supply pipe 2 and the atomizing pipe 3 are both connected to the external desulfurization reagent supply pipeline.

[0044] When the device is working, the flue gas to be treated generated during the ship's travel enters the spray desulfurization chamber 102 through the flue gas inlet 104. At this time, the desulfurization reagent in the external desulfurization reagent supply pipeline passes through the liquid supply pipe 2 and the spray pipe 202, and is sprayed downward from the spray hole 203 to the inside of the spray desulfurization chamber 102. The flue gas rises and contacts the desulfurization reagent sprayed in the spray desulfurization chamber 102 to complete the desulfurization operation. In the subsequent process, the flue gas continues to rise through the flue gas transfer interface 105 and enters the inside of the atomizing desulfurization chamber 103 for a second and more detailed desulfurization. Sulfur operation: During this process, the desulfurization reagent is sprayed out in an atomized manner through the atomizing nozzle 301 installed on the atomizing pipe 3. The desulfurization reagent is fully and comprehensively filled in the atomizing desulfurization bin 103 after being atomized. At this time, the flue gas that has undergone one desulfurization flows into the atomized desulfurization reagent that is fully filled in the atomizing desulfurization bin 103 through the flue gas transfer interface 105. Since the flue gas has been desulfurized once in the spray desulfurization bin 102, the sulfur emissions in it are slightly dispersed and can be more comprehensively neutralized under the action of atomization contact.

[0045] By arranging two upper and lower atomizing desulfurization chambers 103 and a spray desulfurization chamber 102 inside the tower body 1, and opening a spray hole 203 on the spray pipe 202 inside the spray desulfurization chamber 102 to spray a large flow of desulfurization reagent, an atomizing nozzle 301 is provided on the atomizing pipe 3 inside the atomizing desulfurization chamber 103 to spray the desulfurization reagent in an atomized manner. One coarse and one fine, two different desulfurization methods are carried out continuously, which is conducive to making the flue gas in the spray desulfurization chamber 102 and the atomizing desulfurization chamber 103 more fully and comprehensively contact with the desulfurization reagent, to a certain extent, improve the removal effect of the device on sulfur emissions in the flue gas, and can improve the full mixing of the desulfurization reagent and the flue gas without the help of other mixing structures. Therefore, there is no need to use energy to drive the mixing structure, which to a certain extent improves the energy-saving effect of the device.

When the device is working, by installing the fan 4 in the middle position of the flue gas transfer interface 105, auxiliary transportation can be provided for the flue gas inside the flue gas transfer interface 105, which can improve the smoothness and efficiency of the flue gas entering the secondary desulfurization chamber 103 to a certain extent. At the same time, the installation of the fan 4 and the flue gas transfer interface 105 is achieved by connecting the flange and the bolts, which is conducive to the convenient disassembly of the fan 4, and improves the maintenance convenience of the device to a certain extent.

By setting the atomizing tube 3 rotatable and cooperating with the atomizing nozzle 301 to spray the desulfurization reagent in atomization, the atomized desulfurization reagent can be more fully and comprehensively filled in the atomizing desulfurization chamber 103, thereby improving the comprehensiveness of the secondary desulfurization of the flue gas in the atomizing desulfurization chamber 103. By movably sleeved the pipe sleeve 304 on the outside of the shaft tube 302 connected to the inside of the atomizing tube 3, the stability of the desulfurization reagent supply during the rotation of the atomizing tube 3 can be guaranteed.

The driving component includes a ball 5 movably placed in the middle position of the partition 101, and the outer side of the ball 5 is connected to a surrounding cable 502. The inner side of the spray desulfurization chamber 102 is fixedly installed with an inner chamber wall 503. An annular space is formed between the spray desulfurization chamber 102 and the inner chamber wall 503. A plurality of vertical partitions 504 are evenly fixed around the inside of the annular space. The annular space is divided into hydraulic chambers 505 corresponding to the plurality of cables 502 by the partitions 504.

Due to the oil inlet pipe 508 and A one-way valve is installed inside the oil outlet pipe 509 to limit the internal flow direction. During the upward movement of the valve block 506, the space for storing hydraulic oil inside the hydraulic chamber 505 increases, and the hydraulic oil inside the oil tank 602 enters the hydraulic chamber 505 along the annular pipe a6 and the oil inlet pipe 508. When the pull of the subsequent cable 502 is relaxed, the valve block 506 falls back, and the hydraulic oil sucked into the hydraulic chamber 505 is squeezed into the annular pipe b601 through the oil outlet pipe 509, and then enters the volute 603.

[0054] Since multiple cables 502 are arranged around the outside of the sphere 5, during the movement of the sphere 5, there must be a valve block 506 inside the hydraulic chamber 505 that is pulled up, and a valve block 506 inside the hydraulic chamber 505 that is reset downward, so that as long as the sphere 5 rolls due to the shaking of the ship, the hydraulic oil is continuously pumped into the interior of the volute 603. During the continuous flow of the hydraulic oil, the turbofan 604 is pushed to drive the shaft 303 to rotate, providing power for the rotation of the atomizing tube 3. During the rotation process, the atomizing tube 3 enhances the comprehensiveness of the desulfurization reagent sprayed from the atomizing nozzle 301 thereon, so that the atomized desulfurization reagent is fully filled in the atomizing desulfurization chamber 103, further enhancing the adequacy of the contact between the desulfurization reagent and the flue gas inflow emissions, which is conducive to improving the comprehensiveness of the desulfurization.

[0055] By movably placing the ball 5 inside the atomizing desulfurization chamber 103, with the help of the shaking of the ship during its travel, the ball 5 is driven to roll freely inside the atomizing desulfurization chamber 103, and with the help of the connection of the cable 502, the valve block 506 is driven to move inside the hydraulic chamber 505, and the oil inlet pipe 508 and the oil outlet pipe 509 and the internal one-way valve restriction are combined to realize the circulation drive of the hydraulic oil inside the annular pipe a6, and then the turbofan 604 inside the volute 603 is driven to rotate through the flow of hydraulic oil, providing power for the rotation of the atomizing pipe 3. The active drive of the atomizing pipe 3 can be completed without providing additional energy-consuming drive parts for the device, which is beneficial to energy saving.

[0056] See also Figure 1 The outer side of the ball 5 is movably sleeved with a ring 501, and multiple cables 502 are fixedly connected to the outer end wall of the ring 501. When the device is working, the ring 501 is movably sleeved on the outer side of the ball 5, and the ring 501 is used as a transfer medium between the cable 502 and the ball 5 to avoid the ball 5 being affected by the entanglement of the cable 502 during the movement inside the atomizing desulfurization chamber 103. To a certain extent, the strength of driving the ball 5 to roll during the shaking of the ship is improved, which is conducive to providing more stable power for driving the hydraulic oil of the device.

[0057] See also Figure 7 and Figure 8 The cable 502 is bent downward in an L shape and then movably inserted into the hydraulic chamber 505. A guide wheel rotatably installed inside the partition 101 is provided at the L-shaped bending part of the cable 502. The cable 502 is movably placed on the outside of the guide wheel. When the device is working, the bending position of the cable 502 is guided by the guide wheel, which can avoid wear at the through position corresponding to the inside of the atomizing desulfurization chamber 103 during the up and down pulling of the cable 502, thereby helping to improve the service life of the cable 502.

[0058] See also Figure 8 A symmetrically arranged spring 507 is fixedly installed at the bottom of the valve block 506, and the lower end of the spring 507 is fixedly connected to the bottom inner end wall of the hydraulic tank 505. When the device is working, the spring 507 is fixedly connected between the valve block 506 and the bottom inner end wall of the hydraulic tank 505, so that after the valve block 506 is pulled upward by the cable 502, the spring 507 is stretched synchronously. When the pull of the cable 502 is relaxed, the spring 507 rebounds and resets, which can provide a stable driving force for the downward movement of the valve block 506, which is conducive to ensuring the stable downward reset of the valve block 506, and to a certain extent ensures the working stability of the device.
