Description

A portable urea solution storage tank for thermal power plants Technical Field

[0001] This application relates to the field of mobile storage technology, and in particular to a mobile storage tank for urea solution used in thermal power plants. Background Technology

[0002] Urea, also known as urea or carbamide, is an organic compound composed of carbon, nitrogen, oxygen, and hydrogen, with the chemical formula H4N2O or CO(NH2)2. It is a white crystalline solid and one of the simplest organic compounds. Urea is a major nitrogenous end product of protein metabolism in mammals and certain fish.

[0003] The primary application of urea in thermal power plants is as a reducing agent in Selective Catalytic Reduction (SCR) denitrification technology. SCR technology is a widely used flue gas denitrification technology that reduces nitrogen oxides (NOx) emissions into nitrogen and water in the atmosphere by using a catalyst.

[0004] However, existing dissolving tanks for urea solution preparation have some shortcomings in use. During the receiving operation, the operator needs to place the collection bucket below the discharge port. To prevent the initial bucket from shifting due to the impact of the discharge, the operator needs to hold the collection bucket by hand until enough urea solution has been collected and the bucket no longer shifts before releasing their grip. This operation is not only time-consuming but also labor-intensive.

[0005] To address this issue, we propose an improved urea solution storage tank. This new tank is designed to simplify the receiving process and reduce the workload for workers. Summary of the Invention

[0033] To make the above-mentioned objectives, features and advantages of this application more apparent and understandable, the specific embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0034] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application may also be implemented in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0035] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of this application. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0036] Example 1

[0037] Referring to Figures 1-3, this is the first embodiment of the present application. This embodiment provides a mobile storage tank for urea solution in a thermal power plant, which includes a storage component 100, including a tank body 101, a protective shell 102 disposed on the outer wall of the tank body 101, an interceptor plate 102a disposed on the end face of the protective shell 102, and a blocking member 103 disposed on the inner wall of the tank body 101.

[0038] The moving component 200 includes a tray 201, a moving wheel 202 disposed at the bottom of the tray 201, a moving block 203 disposed on the outer wall of the tray 201, a first inclined surface 203a disposed on the outer wall of the moving block 203, a second inclined surface 203b disposed on the other side of the outer wall of the moving block 203, and a first groove 203c disposed on the surface of the moving block 203.

[0039] The tank 101 is divided into two parts: one part is a cylindrical structure with a closed lower end and an open upper end, and the other part is a semi-circular spherical cap. The protective shell 102 is also semi-circular spherical cap in shape. Four intercepting plates 102a are fixedly installed on the lower surface of the protective shell 102. The protective shell 102 and the intercepting plates 102a together constitute the protection of the tank 101. At the same time, a plug 103 is installed at the upper end of the tank 101 to close the tank when it is full and to collect and store the urea solution.

[0040] The tray 201 is a cylindrical sleeve with a sealed bottom. A movable block 203 slides along the outer wall of the tray 201, penetrating the tray 201. The movable block 203 has a first inclined surface 203a near its outer surface and a second inclined surface 203b near its inner surface. When the protective shell 102 moves downwards, it pushes the interceptor plate 102a downwards. Simultaneously, the interceptor plate 102a slides along the surface of the first inclined surface 201a, pushing the movable block 203 into the tray 201. At this time, the movable block 203 lifts the tank 101, opening the blockage 103 of the tank 101 and aligning it with the discharge port at the bottom of the dissolving tank. Four casters 202 are installed on the lower surface of the tray 201. To prevent the tank 101 from moving due to impact, the casters 202 are self-fixing omnidirectional wheels. The technology is existing and will not be described in detail. After the liquid inside the tank 101 is filled, the tank 101 is pushed away, and then the protective shell 102 is pushed upward. The tank 101 slides along the surface of the second inclined surface 203b, and then the moving block 203 is pushed outward. The first slide groove 203c is exposed outside the tray 201, and the protective shell 102 is pushed downward. The intercepting plate 102a at the bottom of the protective shell 102 slides into the interior of the first slide groove 203c. The tank 101 exerts an outward force on the moving block 203 on the outer wall. In addition, the moving block 203 does not exert an upward pushing force. Therefore, when the intercepting plate 102a slides into the interior of the first slide groove 203c, the moving block 203 has a limiting effect on the protective shell 102, so that there is a certain space between the tray 201 and the surface of the tank 101. If a collision occurs, direct contact with the tank 101 is avoided.

[0041] Example 2

[0042] Referring to Figures 1-8, this is the second embodiment of the present application, which differs from the first embodiment in that it further includes: In the previous embodiment, the mobile storage tank for urea solution used in thermal power plants includes a tank body 101 with a fixed platform 101a on its outer wall, and an interceptor plate 102a penetrating through the fixed platform 101a.

[0043] There is a circular fixed platform 101a on the outer wall of the tank 101. The intercepting plate 102a passes through the fixed platform 101a. The advantage of designing the fixed platform 101a is that it can prevent mechanical handling from directly contacting the surface of the tank 101 and prevent the gripper from directly clamping the intercepting plate 102, thus avoiding wear on both.

[0044] The end face of the tank body 101 is provided with a first channel 101b, and the end face of the protective shell 102 is provided with a second channel 102b; the second channel 102b slides along the outer wall of the first channel 101b.

[0045] The upper surface of the tank 101 is fixedly equipped with a cylindrical first channel 101b, and the upper surface of the protective shell 102 is equipped with a similar second channel 102b, and the inner wall of the second channel 102b can slide along the outer wall surface of the first channel 101b.

[0046] The blocking component 103 includes: a first channel 101b with an array of closing plates 103a inside; a first slide rod 103a-1 at both ends of the closing plate 103a; a track disk 103b installed on the inner wall of the first channel 101b; a second slide groove 103b-1 on the surface of the track disk 103b for the first slide rod 103a-1 to slide on; a disc 103c inside the first channel 101b; a third slide groove 103c-1 on the surface of the disc 103c near the closing plate 103a for the first slide rod 103a-1 to slide on; and a second slide rod 103c-2 on the outer wall of the disc 103c, which passes through the first channel 101b.

[0047] The blocking component 103 is installed inside the first channel 101b. Multiple closing plates 103a are arranged in an array, with each closing plate 103a fitting against each other. The fitting surfaces form a triangle, and a sealing gasket is fitted onto the surfaces of the fitting surfaces. A disc 103c is above the closing plates 103a, and a track disk 103b is below the closing plates 103a. The lower surface of the disc 103c has a hexagonal third groove 103c-1. A first sliding rod 103a-1, fixedly mounted on the upper surface of the closing block 103a, can slide along one side of the hexagonal third groove 103c-1. The track disk 103b passes through... The plate 103a has six second sliding grooves 103b-1, each corresponding to one side of a hexagonal third sliding groove 103c-1, and the second sliding groove 103b-1 and the corresponding hexagonal third sliding groove 103c-1 are not parallel. The first sliding rod 103a-1 on the lower surface of the closing plate 103a slides along the inside of the second sliding groove 103b-1, and the upper and lower sliding rods of the closing plate 103a are both cylindrical, with their axes on the same straight line. Therefore, when the second sliding rod 103c-2 is pushed to drive the disc 103c to rotate, the closing plates 103a will either fit together and rotate to unfold, or fit together and rotate to close.

[0048] The inner wall of the second channel 102b is provided with a fourth slide groove 102b-1 for the second slide rod 103c-2 to slide.

[0049] To facilitate operation, a fourth groove 102b-1 is provided on the inner surface of the second channel 102b. The fourth groove 102b-1 is an upward spiral groove. The second slide rod 103c-2 extends through the first channel 101b into the interior of the fourth groove 102b-1. It should be noted that when the protective shell 102 moves downward, in order to drive the second slide rod 103c-2 to slide and thus drive the disc 103c to rotate, a horizontal groove is dug in the first channel 101b to provide sliding space for the second slide rod 103c-2.

[0050] In summary, when urea solution needs to be collected, the protective shell 102 is pushed downwards. The protective shell 102 pushes the moving block 203 into the tray 201. Due to the restriction of the moving block 203 by the intercepting plate 102a fixed on the lower surface of the protective shell 102, the moving block 203 will lift the tank 101 and will not move outwards. During the downward movement of the protective shell 102, the second channel 102b drives the disc 103c to rotate, opening the first channel 101b, and then the solution is injected. When the tank 101 is full, the tank 101 is moved away to remove residual liquid from the blockage 103. Then the protective shell 102 is moved upwards, releasing the restriction of the moving block 203. Subsequently, the tank 101 moves downwards, causing the protective shell 102 to move downwards as well. Then the protective shell 102 moves downwards, and the intercepting plate 102a enters the first chute 203c. This design... The advantage is that after the solution is collected, the protective shell 102, tray 201, and tank 101 are indirectly connected, making movement more stable. Simultaneously, when proceeding to the next step, the fixed platform 101a is directly lifted, at which point the tank 101 and tray 201 separate. The interceptor plate 102a will not move relative to the tank 101, allowing the tank 101 and protective shell 102 to be directly aligned with the injection port of the next process for installation. When the protective shell 102 contacts the injection port, it will push the protective shell 102, reopening the first channel 101b. This eliminates the need to rebuild the connection device between the tank 101 and the next process. Furthermore, the moving component 200 can be separated from the storage component 100, allowing it to be used in conjunction with the next storage component 100.

[0051] Example 3

[0052] Referring to Figures 1-8, this is the third embodiment of the present application, which differs from the previous two embodiments in that: the end face of the tray 201 is provided with a damper 204, and a first elastic member 205 is sleeved on the outside of the damper 204.

[0053] The bottom inner surface of the tray 201 is fixedly equipped with a damper 204. There are four dampers 204 in an array, and the outer wall of each damper 204 is fitted with a first elastic element 205. The first elastic element 205 is a compression spring. The damper 204 and the first elastic element 205 are combined to provide a certain buffering effect on the tank 101. After the liquid is filled, the protective shell 102 is pushed upward, and the downward movement of the tank 101 will become slower, making the whole device safer and more reliable.

[0054] The damper 204 has a support plate 206 at the end away from the tray 201. The surface of the support plate 206 is provided with a sleeve 206a, and the inner wall of the sleeve 206a is provided with a first slider 206a-1.

[0055] The sleeve 206a has a support rod 207 that slides inside. The outer wall of the support rod 207 has a reset groove 207a for the first slider 206a-1 to slide. The other end of the support rod 207 is connected to the moving wheel 202.

[0056] A support plate 206 is fixed above the damper 204, which increases the contact surface with the tank body 101 and the force-bearing surface. At the same time, four sleeves 206a are arranged in an array on the lower surface of the support plate 206. The support rod 207 is slidably connected to the sleeves 206a. Meanwhile, the first slider 206a-1 can slide along the inside of the reset groove 207a, thereby controlling the moving wheel 202. It should be noted that there are four moving wheels 202. During installation, two symmetrical moving wheels 202 are installed in parallel, and two adjacent moving wheels are installed perpendicularly.

[0057] The reset groove 207a includes a movable channel 207a-1 on the outer wall of the support rod 207, and the surface of the movable channel 207a-1 is provided with an array of rhomboid blocks 207a-2.

[0058] A first limiting groove 207a-3 is formed between the rhomboid blocks 207a-2.

[0059] A first circular groove 207a-4 and a second circular groove 207a-5 are formed between the rhomboid block 201a-2 and the inner wall of the movable channel 207a-1.

[0060] A bearing 208 is provided between the support rod 207 and the tray 201.

[0061] The movable channel 207a-1 makes the radius of the middle part of the support rod 207 smaller than the radius of the support column 207. There is a rhombus block 207a-2 on the surface of the movable channel 207a-1. Two rhombus blocks 207a-2 are symmetrically arranged, and the two corners of the rhombus block 207a-2 are close to each other to form a vertical surface. The vertical surface forms a first limiting groove 207a-3. The distance between the upper and lower corners of the rhombus block 207a-2 and the upper and lower surfaces of the movable channel 207a-1 forms a first circular groove 207a-4 and a second circular groove 207a-5.

[0062] It should be noted that the movable wheels are no longer omnidirectional wheels, but ordinary wheels. A support rod 207 is fixedly installed on the upper surface of the wheel, and a bearing 208 is fixedly installed on the outer wall of the support rod 207. When not in use, the first slider 206a-1 inside the sleeve 206a on the lower surface of the disc 206 is in the position of the first circular groove 207a-4. At this time, pushing the device does not affect the free rotation of the support column 207. When it is needed, the protective shell 102 is pushed down, and the movable block 203 will move to the lower surface of the support plate 206. At this time, the first channel 101b on the surface of the tank 101 opens, the protective shell 102 contacts the surface of the tank 101, and continues to push down, driving the support plate 206 to move downward. The first slider 206a-1 on the inner wall of the sleeve 206a moves along the rhombus block 207a. The surface above -2 slides, simultaneously driving the support rod 207 to rotate, resetting the moving wheel 202 to its initial installation state and preventing the entire device from moving. At this time, the first slider 206a-1 displaces the first limiting groove 207a-3, restricting the rotation of the moving wheel 202. The second channel 102b above the protective shell 102 abuts against the outlet of the dissolving tank. Then, the solution is injected. After filling, the entire device is pushed away, pushing the protective shell 102 upward. Then, the first channel 101b of the tank 102 closes. Under the action of the damper 205 and the first elastic element 205, the tank 101 slowly moves downward, starting to squeeze the first elastic element 205. Then, the first slider 206a-1 enters the second circular groove 207a-5, and the support rod 207 can rotate freely again, allowing the entire device to move freely.
