Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of dust and mercury removal equipment, and particularly relates to a high-efficiency dust and mercury removal equipment based on ultrasonic technology. BACKGROUND

[0002] In the field of industrial production, the equipment such as coal-fired boiler, waste incinerator and cement combustion device, etc. in the operation process, the flue gas emitted often contains various harmful substances, such as dust, sulfur oxides (SOx), nitrogen oxides (NOx), etc., and also contains heavy metals such as mercury (Hg), arsenic (As), cadmium (Cd), lead (Pb), selenium (Se) and their compounds. Among them, metallic mercury (HgO) is extremely easy to release into the atmosphere from the flue due to its high vapor pressure at room temperature. Mercury is extremely harmful to human health, and long-term contact or ingestion of mercury can damage important organs such as the nervous system and the kidneys. In view of this, strict supervision of mercury in flue gas and development of more efficient and accurate mercury removal technology have become a top priority.

[0003] In the related art, a flue gas mercury removal equipment includes a tank body installed on the ground in the vertical direction, an air inlet pipe for injecting mercury-containing flue gas is installed on the upper part of the tank body, an air outlet pipe is installed on the vertical side wall of the lower part of the tank body, a waste discharge outlet is installed on the bottom of the tank body, a dust filter screen and a mercury removal assembly using ultrasonic technology are installed on the inner wall of the tank body, and the dust filter screen is located above the mercury removal assembly; after the mercury-containing flue gas enters the tank body, the dust is removed by the dust filter screen first, and then the mercury removal assembly is processed. The mercury removal assembly includes an ultrasonic generator and an atomizing nozzle and other components, the ultrasonic generator generates high-frequency vibration, the liquid containing mercury removal agent is atomized into small droplets through the atomizing nozzle, the droplets fully contact with the flue gas, and the mercury is removed through chemical reaction or physical adsorption, and finally the purified flue gas is discharged from the air outlet pipe.

[0004] Although the above-mentioned flue gas mercury removal equipment can achieve the mercury removal function to a certain extent, there are still obvious deficiencies in actual application. The minimum height of the equipment is about 2 meters, and the weight reaches about 200 kilograms, so when the equipment needs to be moved, the weight is difficult for a single worker to carry. The worker must first remove the fixing structure of the tank body bottom and the ground, which is not only cumbersome but also time-consuming. Then multiple workers need to be arranged to cooperate to carry, which not only increases the labor cost but also is low in overall moving efficiency. In the case of the changeable industrial production environment, this inefficient moving method is difficult to meet the demand of quickly adjusting the position of the equipment, and there is room for improvement. SUMMARY

[0005] The purpose of the present application is to provide a high-efficiency dust and mercury removal equipment based on ultrasonic technology, which solves the problems of the above-mentioned mercury removal equipment that is inconvenient and low in efficiency when adjusting the position in a short distance.

[0006] The application provides a high-efficiency dust and mercury removal equipment based on ultrasonic technology. The high-efficiency dust and mercury removal equipment based on ultrasonic technology comprises a vertically-installed tank body and a support frame fixed to the bottom side of the tank body, the upper part of the tank body is fixed with an air inlet pipe, the bottom is fixed with a pollution discharge pipe, and the outer periphery of the lower part is fixed with an exhaust pipe, and the inner wall of the tank body is provided with a dust removal assembly and a mercury removal assembly; the bottom side of the support frame is fixed with a base plate, the bottom side of the base plate is fixed with a plurality of casters with a locking function, and the upper surface edge of the base plate is provided with a towing handle.

[0007] By adopting the above technical scheme, when the equipment needs to be moved, the fixed structure of the tank body and the ground does not need to be removed, and a single person can easily pull the tank body by means of the towing handle and the casters, thereby avoiding the cumbersome removal and multi-person cooperation process, greatly saving time and labor cost, significantly improving the efficiency and convenience of short-distance position adjustment of the equipment, and better adapting to the requirement of quickly adjusting the position of the equipment under the changeable industrial production environment.

[0009] By adopting the above technical scheme, the adjusting rods can be rotatably adjusted and fixed relative to the base plate, and detachably connected to the connecting plate, so that the towing handle can be flexibly adjusted in form according to different use scenarios and requirements. When the equipment is moved, it can be adjusted to a suitable angle for easy pulling.

[0010] Optionally, the adjusting rod comprises a first screw, a fixed rod connected to one end of the base plate, and a sliding rod connected to one end of the connecting plate, an installation cavity for the sliding rod to insert and slide is formed in the end of the fixed rod away from the base plate, and the first screw is used to fix the overall length of the fixed rod and the sliding rod after telescopic adjustment.

[0011] By adopting the above technical scheme, the length of the towing handle can be flexibly adjusted according to actual use requirements, such as adapting to different spaces or operation habits when the equipment is moved, and the length can also be adjusted to better meet the support and limiting requirements when supporting the tank body or improving the connection stability of the exhaust pipe, thereby greatly enhancing the adaptability and operation flexibility of the equipment and improving the practicality and use effect of the equipment in different scenarios.

[0012] Optionally, the opposite sides of the connecting plate are rotatably connected to the ends of the two sliding rods away from the base plate, and the outside of the sliding rod is provided with a locking piece for locking the rotating state of the connecting plate.

[0013] By adopting the technical scheme, the adapter plate is rotatably connected with the end of the sliding rod, and the sliding rod is externally provided with a locking member, so that the adapter plate can be flexibly rotated to a suitable angle according to different use scenarios, for example, the adapter plate is rotated to a horizontal state to support the tank body when the tank body is moved over a long distance, and the adapter plate is adjusted to a corresponding angle to improve the connection stability of the exhaust pipe, and then the locking member is used to fix the rotating state.

[0014] Optionally, rotating shafts are fixed on opposite sides of the adapter plate, rotating holes are formed in the sides of the two sliding rods that are close to each other and are used for inserting the rotating shafts, a locking screw hole is formed in the adapter plate, a plurality of locking through holes are uniformly formed around the rotating hole on the sliding rod, and the locking member is a locking bolt that is screwed into the locking screw hole after penetrating through the locking through hole.

[0015] By adopting the technical scheme, the adapter plate is rotatably connected with the end of the sliding rod, and the sliding rod is externally provided with a locking member, so that the adapter plate can be flexibly rotated to a suitable angle according to different use scenarios, for example, the adapter plate is rotated to a horizontal state to support the tank body when the tank body is moved over a long distance, and the adapter plate is adjusted to a corresponding angle to improve the connection stability of the exhaust pipe, and then the locking member is used to fix the rotating state.

[0016] Optionally, a limiting notch is formed in the adapter plate; the towing handle can be rotated upward to a vertically upward state, the adapter plate can be rotated to a horizontal state in a direction close to the tank body at this time, the outer circumferential surface of the tank body can be clamped into the limiting notch in this state, the tank body can be placed and transported in a horizontal state when the towing handle abuts against the ground, and the adapter plate is used to support the tank body at this time.

[0017] By adopting the technical scheme, when the towing handle is rotated upward to a vertically upward state, the adapter plate can be rotated to a horizontal state in a direction close to the tank body, so that the outer circumferential surface of the tank body is clamped into the limiting notch, and then the tank body is placed and transported in a horizontal state when the towing handle abuts against the ground, and the adapter plate plays a supporting role. This design makes it unnecessary to use an additional complex supporting structure when the device is transported over a long distance, and a single person can complete the horizontal placement and support operation of the tank body, thereby greatly improving the convenience and safety of transportation, reducing the labor cost and transportation difficulty, and enhancing the applicability of the device in different transportation scenarios.

[0018] Optionally, a positioning plate is provided above the base plate. The two opposite sides of the positioning plate are rotatably connected to the sides of the two fixing rods that are close to each other. A positioning notch is provided on the positioning plate. The positioning plate can be rotated and adjusted and fixed. After the length of the adjusting rod is adjusted, the connecting plate and the positioning plate can rotate towards each other until the surfaces of the limiting notch and the positioning notch abut against each other. The opening formed by the limiting notch and the positioning notch is sleeved on the outer periphery of the exhaust pipe when the traction handle is rotated to the vertical upward position.

[0019] By adopting the above technical solution, a rotatable, adjustable, and fixed positioning plate is set above the base plate, with a positioning notch on it. This notch cooperates with the connecting plate. After the length of the adjusting rod is adjusted, the two plates can rotate towards each other, causing the limiting notch and the positioning notch to abut against each other. When the traction handle is rotated to the vertically upward position, the enclosed opening can be fitted onto the outer circumference of the exhaust pipe. When an external pipe is connected to the exhaust pipe, this opening limits the connection between the external pipe and the exhaust pipe, effectively improving the connection stability and enhancing the practicality and reliability of the equipment in different usage scenarios.

[0020] Optionally, elastic pads are fixed on the inner walls of both the positioning notch and the limiting notch.

[0021] By adopting the above technical solution, when the tank is engaged with the limiting notch or both the limiting notch and the positioning notch simultaneously, the elastic pad can act as a buffer and protector, reducing collisions and wear between the tank and the inner wall of the notch, and extending the service life of the equipment. At the same time, the elastic pad can increase the friction with the tank, making the tank more stable during horizontal transportation or when connected to the exhaust pipe, and less prone to shaking, further improving the safety and reliability of the equipment in different usage scenarios.

[0022] Optionally, the positioning plate can rotate to a state parallel to the positioning plate when the connecting plate supports the tank, and the outer circumferential surface of the tank can be simultaneously engaged in the positioning notch.

[0023] By adopting the above technical solution, when the connecting plate supports the tank, the positioning plate can rotate to a parallel state with the connecting plate, and the outer circumference of the tank can simultaneously engage with the positioning notch. This design allows the positioning plate and the connecting plate to work together to provide more stable support to the tank from different directions, further enhancing the stability of the tank during horizontal transportation, reducing the risk of tank swaying or tipping, ensuring transportation safety, and also improving the rationality and practicality of the overall equipment structure, better adapting to the needs of transportation scenarios.

[0024] Optionally, a protective curtain is provided above the tank, and several hooks are fixedly provided on one side of the protective curtain. A support rod parallel to the connecting plate in the length direction is fixedly provided on the upper side of the air inlet pipe, and a hanging ring for the hooks to be engaged is fixedly provided on the support rod. When the adjusting rod is in the vertical upward position, the connecting plate can be rotated to the position where the limiting notch faces upward. In this position, the side of the connecting plate facing the tank has a storage groove and a cover plate for sealing the storage groove can be detachably installed. The edge of the protective curtain away from the hooks is fixedly connected to the inner wall of the storage groove.

[0025] By adopting the above technical solution, the protective curtain can be stored in the storage slot of the connecting plate and sealed with a cover plate, saving space and not affecting other operations of the equipment; when protection is needed, it can be unfolded to effectively prevent dust, debris and other objects from falling into the tank, keeping the inside of the tank clean. At the same time, this retractable design makes the protective curtain flexible in use, improving the practicality and protective performance of the equipment in different usage scenarios.

[0026] In summary, this application includes the following beneficial technical effects: The equipment is equipped with a support frame with casters and a traction handle on the bottom side of the tank. When the equipment needs to be moved, there is no need to remove the fixed structure between the tank and the ground. A single person can easily drag the tank with the help of the traction handle and casters, avoiding the tedious dismantling and multi-person collaborative handling process, which greatly saves time and labor costs, significantly improves the efficiency and convenience of short-distance position adjustment of the equipment, and can better adapt to the needs of quickly adjusting the position of the equipment in the ever-changing industrial production environment.

[0030] The present application will be further described in detail below with reference to all the accompanying drawings.

[0031] Example: Reference Figure 1 and Figure 2 A high-efficiency dust and mercury removal device based on ultrasonic technology includes a vertically installed tank 1 and a support frame 11 welded and fixed to the bottom side of the tank 1. An air inlet pipe 12 is fixed to the upper part of the tank 1, a sewage pipe 13 is fixed to the bottom, and an exhaust pipe 14 is fixed to the lower outer periphery. A dust removal component 2 and a mercury removal component 3 are provided on the inner wall of the tank 1. The dust removal component 2 is a dust removal screen fixed to the inner wall of the tank 1, and the mercury removal component 3 is located below the dust removal component 2. After the mercury-containing flue gas enters the tank 1 through the inlet pipe 12, it first passes through the dust removal component 2 to remove the dust in the flue gas, and then enters the mercury removal component 3 to remove the mercury compounds in the flue gas. Finally, the flue gas after dust and mercury removal is discharged from the exhaust pipe 14. Then, cleaning liquid can be injected into the tank 1 through the inlet pipe 12 periodically for cleaning, and the wastewater after cleaning is discharged from the drain pipe 13.

[0032] Referring to 2, the mercury removal component 3 includes components such as an ultrasonic generator and an atomizing nozzle, which is a conventional structure and will not be described in detail here; the ultrasonic generator generates high-frequency vibrations, causing the liquid containing the mercury removal agent to be atomized into tiny droplets through the atomizing nozzle. These droplets come into full contact with the flue gas and remove mercury through chemical reaction or physical adsorption. Finally, the purified flue gas is discharged from the exhaust pipe 14.

[0033] Reference Figure 3A movable component 4 is provided below the support frame 11. The movable component 4 includes a base plate 41 fixed to the bottom side of the support frame 11. Four casters 42 with locking function are fixed on the bottom side of the base plate 41, and a traction handle 5 is installed on the edge of the upper surface of the base plate 41. When it is necessary to adjust the installation position of the tank 1, the user can drag the tank 1 on the base plate 41 by a single person through the traction handle 5 and the casters 42.

[0034] Reference Figure 3 and 4 The traction handle 5 includes a connecting plate 54 and two adjusting rods 52 that are rotatably mounted on the upper edge of the base plate 41. The adjusting rod 52 includes a first bolt 521, a fixed rod 522 connected to the base plate 41 at one end, and a sliding rod 523 connected to the connecting plate 54 at one end. The fixed rod 522 has a mounting cavity on its end away from the base plate 41 for the sliding rod 523 to be inserted and slid. The fixed rod 522 has several first through holes, and the sliding rod 523 has a first screw hole; the overall length of the fixed rod 522 and the sliding rod 523 can be adjusted by telescopic extension and retraction, and then the overall length is fixed by using the first bolt 521 to pass through the first through hole and screw into the first screw hole. The upper edge of the base plate 41 is provided with a second bolt 44 and a hinge seat 43 that is hinged to the lower end of the fixing rod 522. The hinge seat 43 is provided with several second through holes and the fixing rod 522 is provided with a second screw hole. By passing the second bolt 44 through different second through holes and screwing it into the second screw hole, the rotation angle of the fixing rod 522 can be adjusted and fixed.

[0035] Reference Figure 4 and Figure 5 The connecting plate 54 has a limit notch 541; the ends of the two adjusting rods 52 away from the base plate 41 are detachably connected to the opposite sides of the connecting plate 54, and the connecting plate 54 ensures that the two adjusting rods 52 rotate synchronously for adjustment; the opposite sides of the connecting plate 54 are rotatably connected to the ends of the two sliding rods 523 away from the base plate 41, and the sliding rods 523 are provided with locking members 53 on the outside to lock the rotation state of the connecting plate 54; When the tank 1 needs to be moved a long distance, it can be adjusted from a vertical position to a horizontal position and supported. The specific method is as follows: First, rotate the traction handle 5 upward to a vertical position and fix it. Then, rotate the connecting plate 54 towards the direction of the tank 1 to a horizontal position. The outer circumference of the tank 1 is just inserted into the limiting notch 541 in this position. Finally, the tank 1 can be adjusted to a horizontal position when the traction handle 5 is in contact with the ground. In this way, the traction handle 5 and the connecting plate 54 are used to support the tank 1 in the horizontal transportation state.

[0036] Reference Figure 4 and Figure 5A rotating shaft 542 is fixed on the opposite two sides of the connecting plate 54. A rotating hole for inserting the rotating shaft 542 is opened on the side of the two sliding rods 523 that are close to each other. A locking screw hole is opened on the connecting plate 54. Several locking through holes are evenly opened on the sliding rod 523 around the rotating hole. The locking member 53 is a locking bolt 531 that passes through the locking through hole and is screwed into the locking screw hole.

[0037] Reference Figure 4 and Figure 5 A positioning plate 51 is provided on the upper part of the base plate 41. The two opposite sides of the positioning plate 51 are rotatably connected to the sides of the two fixing rods 522 that are close to each other. A positioning notch 511 is provided on the positioning plate 51. The positioning plate 51 can be rotated, adjusted and fixed. The rotation installation method of the positioning plate 51 is the same as that of the connecting plate 54, and will not be described in detail here. Both the positioning notch 511 and the limiting notch 541 are fixed with elastic pads 512 made of rubber. When the tank 1 is in a horizontal transport state (the traction handle 5 is in contact with the ground), the operator can rotate the positioning plate 51 to a state parallel to the connecting plate 54. At this time, the outer circumference of the tank 1 can be simultaneously inserted into the positioning notch 511, so as to further support the horizontal tank 1 using the positioning plate 51.

[0038] Reference Figure 6 After the length of the adjusting rod 52 is adjusted, the connecting plate 54 and the positioning plate 51 can rotate towards each other until the surfaces of the limiting notch 541 and the positioning notch 511 abut against each other. The exhaust pipe 14 is located on the outer side of the tank 1 facing the traction handle 5. At this time, the opening formed by the limiting notch 541 and the positioning notch 511 is fitted onto the outer periphery of the exhaust pipe 14 when the traction handle 5 is rotated to the vertical upward state. When the external pipe is connected to the exhaust pipe 14, the user can first adjust the traction handle 5 to the vertical upward position, then adjust the rotation state of the connecting plate 54 and the positioning plate 51, and finally adjust the overall length of the adjusting rod 52 so that the openings of the limiting notch 541 and the positioning notch 511 abut against each other. In this way, the openings formed by the positioning notch 511 and the connecting notch further limit the connection between the external pipe and the exhaust pipe 14, thereby improving the connection stability of the connection.

[0039] Reference Figure 7 and Figure 8 A protective curtain 6 is provided above the tank body 1. Two hooks 61 are fixed on one side of the protective curtain 6. The air inlet pipe 12 is located on the side edge of the upper part of the tank body 1 away from the traction handle 5. A support rod 15 with a length direction parallel to the connecting plate 54 is fixed on the upper side of the air inlet pipe 12. A hanging ring 151 for the hooks 61 to be inserted is fixed on the support rod 15. When the adjusting rod 52 is in the vertical upward position, the connecting plate 54 can rotate to the position where the limiting notch 541 faces upward. In this position, the connecting plate 54 has a storage groove 543 on the side facing the tank 1, and a cover plate 544 for sealing the storage groove 543 is fixed by screws. The edge of the protective curtain 6 away from the hook 61 is fixedly connected to the inner wall of the storage groove 543. When the dust removal and mercury removal equipment is used outdoors (in rainy or sunny weather), first turn the traction handle 5 to the vertical position and adjust it to the longest length. Then, turn the connecting plate 54 to the position where the limit notch 541 faces upward. Then, take the protective curtain 6 out of the storage slot 543 and use the hook 61 to insert it into the hanging ring 151 on the support rod 15. In this way, the protective curtain 6 can be used to cover the top of the tank 1.

[0040] The implementation principle of this application embodiment is as follows: When it is necessary to move the tank 1 a short distance: a single person can drag the tank 1 on the base plate 41 by pulling the handle 5 and the caster 42 with locking function, and use the first bolt 521 to adjust the length of the adjusting rod 52 and the second bolt 44 to adjust the rotation angle of the fixing rod 522 to adapt to different movement needs. When the tank 1 needs to be transported horizontally over a long distance: the traction handle 5 is rotated upward and fixed, the connecting plate 54 and the positioning plate 51 are rotated to the horizontal state, the outer circumference of the tank 1 is inserted into the limiting notch 541 and the positioning notch 511, and finally the tank 1 can be adjusted to the horizontal state when the traction handle 5 is in contact with the ground, so as to use the traction handle 5, the connecting plate 54 and the positioning plate 51 to support the tank 1 in the horizontal transport state; When it is necessary to improve the connection stability of exhaust pipe 14: When the external pipe is connected to exhaust pipe 14, adjust the state of traction handle 5, connecting plate 54 and positioning plate 51, and adjust the length of adjusting rod 52 so that the limiting notch 541 and positioning notch 511 surround the opening around exhaust pipe 14 to improve connection stability. When outdoor weather is severe and protection is needed: turn the towing handle 5 to the vertical position and adjust it to the longest position, turn the connecting plate 54 to the limit notch 541 facing upwards, then take out the protective curtain 6, and use the hook 61 to lock into the hanging ring 151 to cover the top of the tank 1.
