Description

Technical Field

[0001] The invention belongs to the technical field of desulfurizing agent feeding, and in particular relates to a speed-controlled and quantity-controlled feeding device for a high-activity desulfurizing agent. Background Art

[0002] High-activity desulfurizer, also known as calcium-based desulfurizer or high-specific surface calcium hydroxide, is made of calcium hydroxide and special additives as the main raw materials through special process technology. The "high activity" of high-activity desulfurizer is mainly reflected in its fine particle size and large specific surface area, which makes it more reactive. This desulfurizer can more effectively react with sulfides (such as sulfur dioxide) in flue gas, converting sulfides into sulfates or thiosulfates, thereby achieving a desulfurization effect.

[0003] When using, the highly active desulfurizer should be added to the desulfurization equipment. Desulfurization equipment is a device specially designed to treat pollutants in flue gas, including but not limited to desulfurization towers, integrated desulfurization and dust removal equipment, etc. These devices are equipped with space and mechanisms for reacting with the desulfurizer, which can ensure that the desulfurizer is in full contact with the flue gas and react chemically, thereby achieving the purpose of desulfurization. Specifically, the desulfurizer is usually added to the inlet or specific location of the desulfurization equipment in the form of powder or granules. As the flue gas flows, the desulfurizer reacts with the sulfide in the flue gas to generate harmless or low-harm substances such as sulfates. Subsequently, through subsequent treatment steps such as dust removal, the desulfurization by-products are separated and removed from the flue gas, and finally the flue gas is purified.

[0013] Preferably, an eccentric wheel is provided at the output end of the vibration motor, a connecting shaft is provided in the middle of the eccentric wheel, and a mounting ring is provided at the end of the output rod, and the mounting ring is rotatably connected to the connecting shaft.

[0014] Preferably, the friction reducing mechanism is a sliding wheel, and the sliding wheel is rotatably arranged in the mounting groove.

[0015] Preferably, the friction reducing mechanism is a magnet, and the magnet is fixed in a mounting groove.

[0016] The advantages of the present invention are: 1. The present invention drives the feed plate to reciprocate through the reciprocating drive mechanism, which can accurately control the time and frequency of the material entering the feed channel through the feed hole, thereby realizing accurate control of the desulfurizer feed speed and feed amount. It is particularly important to strictly control the reaction rate and desulfurizer ratio process, which helps to improve the desulfurization effect.

[0017] 2. The present invention provides a stable horizontal driving force through a reciprocating motor, so that the vibration motor and the output rod can move precisely horizontally along the slide rail.

[0018] 3. The present invention can directly and efficiently absorb the heat generated by the friction between the stopper plate and the inner bottom of the feed seat by injecting coolant into the cooling cavity and the cooling channel. This direct cooling method is more effective than heat dissipation through natural convection of air, and can quickly reduce the temperature of the friction surface and prevent heat accumulation from affecting the quality of the desulfurizer.

[0019] 4. The present invention realizes active circulation of the coolant. When the output end of the reciprocating drive mechanism moves, it presses the first elastic sleeve, thereby pushing the coolant to flow through the cooling cavity and the cooling channel. This active cooling cycle is more efficient than natural convection or passive heat dissipation.

[0020] 5. The present invention realizes directional flow of the coolant by controlling the rotation angle of the first spoiler and the second spoiler. When the first elastic sleeve is squeezed, the coolant mainly enters the inlet channel to cool the stopper plate; when reset, the coolant flows back through the return channel to form a closed loop. This design optimizes the flow path of the coolant and improves the circulation efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] Embodiment 1, combination Figure 1-2 A high-activity desulfurizing agent speed-controlled and quantity-controlled feeding device comprises a base 1, a barrel 2, a feeding seat 3, a feeding plate 4, a reciprocating driving mechanism and a feeding channel 5. The feeding seat 3 is mounted on the base 1, the barrel 2 is mounted on the top of the feeding seat 3, and a connecting hole 6 is provided above the feeding seat 3. The top of the first connecting hole 6 is connected to the bottom of the barrel 2. The barrel 2 is filled with desulfurizing agent powder, and the desulfurizing agent powder enters the connecting hole 6 along the bottom of the barrel 2 during feeding.

[0037] A feed plate 4 is provided in the middle of the feed seat 3 for horizontal sliding, and a feed hole 7 is provided on the feed plate 4. The end of the feed plate 4 is connected to the reciprocating drive mechanism, and a feed channel 5 is provided on the side of the feed seat 3. The reciprocating drive mechanism drives the feed plate 4 to reciprocate so that the feed hole 7 is repeatedly connected with the first connecting hole 6 and the feed channel 5, and the feed channel 5 is not coaxial with the connecting hole 6. When the reciprocating drive mechanism drives the feed plate 4 to move to the designated position on the right, the upper part of the connecting hole 6 is connected with the feed hole 7 on the feed plate 4, and the desulfurizer powder enters the feed hole 7 and realizes quantitative feeding. After that, the reciprocating drive mechanism drives the feed plate 4 to move to the designated position on the left, and the lower part of the connecting hole 6 is connected with the feed channel 5 and quantitative desulfurization is put into the feed channel 5. By driving the feed plate 4 to reciprocate by the reciprocating drive mechanism, the time and frequency of the material entering the feed channel 5 through the feed hole 7 can be accurately controlled, thereby realizing accurate control of the desulfurizer feeding speed and feeding amount. It is particularly important to strictly control the reaction rate and the ratio of the desulfurizer, which helps to improve the desulfurization effect. Since the feed amount of the desulfurizer can be accurately controlled, the material waste and environmental pollution caused by excessive feed are avoided. At the same time, the reaction efficiency decline and product quality fluctuation caused by uneven feed are also reduced.

[0038] A sliding flow-limiting rod 23 is provided above the feed seat 3, and a flow-limiting hole 24 is provided on the sliding flow-limiting rod 23. The sliding flow-limiting rod 23 slides through the connecting hole 6, and the sliding limit rod changes the relative position of the flow-limiting hole 24 and the connecting hole 6 to limit the flow rate. By adjusting the position of the sliding flow-limiting rod 23, the overlap degree between the flow-limiting hole 24 and the connecting hole 6 can be accurately controlled, thereby achieving further fine adjustment of the material flow rate. It can ensure that the material enters the next process at a predetermined rate and amount, avoiding a decrease in production efficiency or product quality problems caused by flow fluctuations. Compared with traditional valve systems or regulating devices, the flow rate can be adjusted through a simple sliding operation, which greatly simplifies the operation process and reduces the difficulty of operation.

[0039] Combination Fig.10The reciprocating drive mechanism includes a reciprocating motor 25 and a vibration motor 26. A slide rail 27 and a fixed plate 28 are provided on the base 1. The reciprocating motor 25 is fixed on the fixed plate 28. The output end of the reciprocating motor 25 is connected to a vibration motor seat 29. The bottom of the vibration motor seat 29 is slidably connected to the slide rail 27. The vibration motor 26 is fixed on the vibration motor seat 29. The output end of the vibration motor 26 is connected to an output rod 30. An eccentric wheel 31 is provided at the output end of the vibration motor 26. A connecting shaft 32 is provided in the middle of the eccentric wheel 31. A mounting ring 33 is provided at the end of the output rod 30. The mounting ring 33 is rotatably connected to the connecting shaft 32. The reciprocating motor 25 drives the vibration motor 26 and the output rod 30 to move horizontally, and the vibration motor 26 can drive the output rod 30 and the feed plate 4 to vibrate. The vibration motor 26 uses the eccentric wheel 31 to rotate to form a vibration effect, which can reduce the influence of noise. The reciprocating motor 25 provides a stable horizontal driving force, so that the vibration motor 26 and the output rod 30 can move precisely horizontally along the slide rail 27. The vibration motor 26 generates a vibration effect through the rotation of the eccentric wheel 31. This vibration can effectively promote the flow and dispersion of the desulfurizer powder and reduce the blockage and agglomeration problems of the desulfurizer powder during transportation or processing.

[0040] Combination Figure 3 The lower bottom surface of the feed plate 4 is located on both sides of the feed hole 7 and is provided with a stopper plate 8 and a mounting groove 9. The stopper plate 8 protrudes from the lower bottom surface of the feed plate 4. The mounting groove 9 is provided with a friction reducing mechanism. The friction reducing mechanism makes a gap between the lower bottom surface of the feed plate 4 and the inner side of the feed seat 3. In this embodiment, the friction reducing mechanism is a sliding wheel 34, which is rotatably arranged in the mounting groove 9, and the sliding wheel 34 is used to support the feed plate 4. Since the feed plate 4 will generate a large friction with the inner bottom of the feed seat 3 under the action of gravity, the high temperature generated by the friction is likely to affect the chemical properties of the desulfurizer, so the sliding wheel 34 is provided to reduce the friction contact surface. At the same time, the stopper plate 8 is used to contact with the inner bottom of the feed seat 3 to achieve a sealing effect at the bottom of the feed hole 7, so as to avoid changes in the amount of desulfurizer powder during movement. The stopper plate 8 can be a ring or a square structure. Only by contacting the stopper plate 8 with the inner bottom of the feed seat 3 can the heat generated by friction be reduced. By arranging a sliding wheel 34 as a friction reducing mechanism on the lower surface of the feed plate 4, the direct contact area between the feed plate 4 and the inner bottom of the feed seat 3 is greatly reduced, thereby significantly reducing friction and wear. This not only prolongs the service life of the feed plate 4 and the feed seat 3, but also reduces the heat generated by friction, which helps to protect the quality of the desulfurizer powder.

[0041] Combination Figure 4-5A cooling cavity 10 is provided inside the feed plate 4, and a coolant with a long service life, such as an ethylene glycol-based coolant or an oil-based coolant, is stored in the cooling cavity 10. A cooling channel 11 is vertically connected to one end of the cooling cavity 10, and the cooling channel 11 extends to the stop plate 8. The coolant in the cooling cavity 10 is also injected into the cooling channel 11 to absorb the heat generated by the friction of the stop plate 8. This direct cooling method is more effective than heat dissipation through natural convection of air, and can quickly reduce the temperature of the friction surface and prevent heat accumulation from affecting the quality of the desulfurizer powder. The selection of coolants with a long service life, such as ethylene glycol-based coolants or oil-based coolants, reduces environmental pollution and waste caused by frequent replacement of coolants.

[0042] A first elastic sleeve 12 is provided at the other end of the cooling chamber 10, and a second elastic sleeve 13 is provided at the bottom of the cooling channel 11. The output end of the reciprocating drive mechanism extends into the cooling chamber 10 and is connected to the first elastic sleeve 12. When the reciprocating mechanism drives the output end to move, it presses the first elastic sleeve 12, and the liquid in the cooling chamber 10 is pressed to squeeze the second elastic sleeve 13, so that the coolant in the cooling chamber 10 flows. The flow of the liquid can better achieve the cooling effect on the stop plate 8, and the active circulation of the coolant is realized. The first elastic sleeve 12 and the second elastic sleeve 13 can both be made of rubber material to ensure a certain elasticity and hardness. The reciprocating drive device first squeezes the first elastic sleeve 12 through the output end, and the first elastic sleeve 12 squeezes the coolant while applying thrust to the feed plate 4, so that the feed plate 4 moves to the left. When the output end of the reciprocating drive device contracts, the first elastic sleeve 12 and the feed plate 4 move to the right again, and the coolant and the feed plate 4 move again. The flow of the coolant can better cover and contact the baffle plate 8, thereby improving the heat transfer efficiency. At the same time, the circulation of the coolant also helps to reduce the temperature of the entire cooling system, further improving the cooling effect on the baffle plate 8.

[0043] A partition guide plate 14 is provided in the cooling channel 11, and the partition guide plate 14 divides the cooling channel 11 into an inlet channel 15 and a return channel 16, so that the coolant can form a clear path during the flow. A first baffle plate 17 is hinged below the partition guide plate 14, and a first limit block 18 and a second limit block 19 are provided below the inlet channel 15. The first limit block 18 and the second limit block 19 allow the first baffle plate 17 to rotate below the inlet channel 15, and the rotation angle range of the first baffle plate 17 is 0°-80°. When the first elastic sleeve 12 is squeezed and contracted for the first time, the second elastic sleeve 13 expands when the liquid in the cooling chamber 10 moves downward, such as Figure 6 As shown in FIG. 1 , the first baffle 17 rotates clockwise, and the lower part of the inlet channel 15 is in an open state. When the first elastic sleeve 12 is reset, the liquid under the cooling channel 11 flows back. Figure 7As shown, under the action of the refluxed coolant, the first baffle 17 rotates counterclockwise, the lower part of the inlet channel 15 is in a closed state, and the coolant refluxes from the reflux channel 16, so that the coolant with a lower temperature in part of the cooling cavity 10 can be continuously sent to the bottom of the cooling channel 11, so as to better absorb the heat of the stopper plate 8.

[0044] A second baffle 20 is hinged above the partition guide plate 14, and a third stopper 21 and a fourth stopper 22 are provided above the outflow channel. The third stopper 21 and the fourth stopper 22 allow the second baffle 20 to rotate above the outflow channel. The rotation angle range of the second baffle 20 is 0°-80°. When the first elastic sleeve 12 is squeezed and contracted for the first time, the liquid in the cooling chamber 10 moves downward, and the second elastic sleeve 13 expands. Under the cooling flow, Figure 8 As shown, the upper part of the return channel 16 is in a closed state to facilitate the coolant to enter the inlet channel 15. When the first elastic sleeve 12 is reset, the liquid under the cooling channel 11 flows back. Fig. 9 As shown, under the action of the refluxed coolant, the upper part of the reflux channel 16 is in an open state, while the lower part of the inlet channel 15 is in a closed state, so that the fluidity of the coolant will be better and the heat absorption effect on the stop plate 8 will be better. By controlling the rotation angle of the first baffle 17 and the second baffle 20, the directional flow of the coolant is realized. When the first elastic sleeve 12 is squeezed, the coolant mainly enters the inlet channel 15 to cool the stop plate 8; when reset, the coolant flows back through the reflux channel 16 to form a closed loop. This design optimizes the flow path of the coolant and improves the circulation efficiency. The directional flow and circulation of the coolant enable the coolant with a lower temperature to be continuously sent to the bottom of the cooling channel 11 to exchange heat with the stop plate 8. At the same time, by controlling the switch state of the inlet channel 15 and the reflux channel 16, it is ensured that the coolant can fully contact and cover the stop plate 8 during the flow process, thereby enhancing the cooling effect. At the same time, through reasonable flow channel design and baffle control, the energy loss of the coolant during the flow process is reduced. The coolant can flow along a predetermined path, avoiding unnecessary eddy currents and turbulence, thereby improving energy utilization efficiency.

[0045] Embodiment 2, combined Fig.11This embodiment has the same parts as the embodiment 1, and the difference between this embodiment and the embodiment 1 is that the friction reducing mechanism in this embodiment is a magnet 35, and the magnet 35 is fixed in the mounting groove 9. A track structure with a magnetic pole opposite to that of the magnet 35 can be provided inside the feed seat 3, so that the magnet 35 can be made into a feed plate 4. The magnet 35 is adsorbed on the mounting groove 9 and the track structure by magnetic force, thereby realizing a contactless connection between the feed plate 4 and the feed seat 3. This contactless design greatly reduces the friction and wear caused by mechanical contact, and the contactless friction design reduces the wear between the feed plate 4 and the feed seat 3, thereby reducing the maintenance cost caused by wear. In addition, due to the high durability of the magnet 35, the cost of replacing worn parts is also reduced.
