Description

Technical Field

[0001] This invention relates to the field of vibration damping equipment technology, specifically to a dust removal and desulfurization equipment for chemical production. Background Technology

[0002] In the process of chemical production, a large amount of waste gas containing dust and sulfides is generated. If this waste gas is directly discharged into the atmosphere, it will cause serious harm to the environment and human health. Therefore, chemical waste gas desulfurization and dust removal equipment is of great importance.

[0003] In the prior art, a chemical desulfurization and dust removal device with publication number "CN223324279U" belongs to the field of chemical desulfurization and improves the problem of poor filter cleaning efficiency. It includes a spray shell, a filter mechanism fixedly connected to the outer surface of the spray shell, a control panel fixedly connected to the outer surface of the filter mechanism, and a cleaning mechanism fixedly connected to the inner wall of the spray shell. The filter mechanism includes an air inlet pipe fixedly connected to the side surface of the spray shell. This application allows for the cleaning of impurities adsorbed on the lower surface of the impurity filter plate by starting a water pump, causing the liquid in the spray shell to flow into a storage tank. The impurities in the liquid are then filtered through a filter frame. By sliding the filter frame, it can be separated from the storage tank, facilitating cleaning of the filter frame. Simultaneously, the water mist sprayed from the atomizing nozzles can adsorb impurities in the exhaust gas, further facilitating filtration of these impurities.

[0004] However, existing technologies still have significant shortcomings, such as:

[0005] Most existing dust removal and desulfurization equipment adopts a combination of spray desulfurization and liquid dust removal. This method involves the desulfurization liquid contacting the flue gas to absorb acidic gases, and the liquid capturing dust particles in the flue gas, thus purifying the exhaust gas. However, existing equipment still has certain shortcomings in actual use. On the one hand, the contact time between the flue gas and the desulfurization liquid is relatively short, and some flue gas is discharged before sufficient reaction, affecting desulfurization efficiency. On the other hand, some of the desulfurization liquid after spraying still has strong activity, but it is usually directly collected and discharged, resulting in low utilization of the desulfurization liquid and increased operating costs.

Detailed Implementation

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Please see Figures 1-6 The present invention provides a technical solution:

[0031] Example 1

[0032] A dust removal and desulfurization device for chemical production includes a desulfurization tank 100, which provides a reaction space for flue gas dust removal and desulfurization. A gas supply pipe 101 is fixedly connected to the bottom of one side of the surface of the desulfurization tank 100, which is used to transport the flue gas to be treated into the interior of the desulfurization tank 100. A drive motor 102 is fixedly connected to one side of the top of the desulfurization tank 100, which provides power to the internal rotating structure. A transmission gear 103 is fixedly connected to the output end of the drive motor 102. A transmission rod 104 is movably connected inside the desulfurization tank 100. The top end of the transmission rod 104 extends through to the top of the desulfurization tank 100 and is movably connected to the desulfurization tank 100. A driven gear 105 is fixedly connected to the top of the surface of the transmission rod 104. The driven gear 105 meshes with the transmission gear 103, so that the drive motor 102 can drive the transmission rod 104 to rotate continuously when it runs.

[0033] The desulfurization tank 100 is equipped with a spray desulfurization mechanism 200 for gas desulfurization. This mechanism can atomize the desulfurization liquid and spray it evenly onto the flue gas flow area, thereby increasing the gas-liquid contact area and enhancing the desulfurization effect.

[0034] The spray desulfurization mechanism 200 includes a support plate 201 fixedly connected to the top of the desulfurization tank 100. The support plate 201 supports the spraying structure and guides the rising flue gas. A first vent 202 is provided on the inner side of the top of the support plate 201. Several first vent 202s are arranged in a ring at equal intervals, allowing the flue gas to pass evenly through the support plate 201 into the upper desulfurization area. The bottom end of the transmission rod 104 extends through to the bottom of the support plate 201 and is movably connected to it, ensuring that the rotation of the transmission rod 104 does not affect the fixation of the support plate 201. A spray hood 203 is fixedly connected to the surface of the moving rod 104. The spray hood 203 is used to drive the spray pipe 205 to rotate synchronously. A second vent 204 is opened on the outer side of the top of the spray hood 203. Several second vents 204 are arranged in a ring and are evenly distributed, so that the flue gas is dispersed again after passing through the first vent 202, thereby improving the uniformity of flue gas distribution. The gas after desulfurization enters the interior of the spray hood 203 and is discharged to the top space of the desulfurization tank 100 through the second vent 204. Then it is discharged through the exhaust pipe 210g, thereby completing the flue gas purification process.

[0035] The spray hood 203 is movably connected to the surface of the support plate 201. A spray pipe 205 is fixedly connected inside the spray hood 203. Several spray pipes 205 are arranged in a ring and are evenly distributed. Atomizing nozzles 206 are fixedly connected to the bottom of the spray pipes 205. Several atomizing nozzles 206 are arranged in a ring and are evenly distributed, used to spray the desulfurization liquid to form a fine liquid mist. A connecting pipe 207 is fixedly connected inside the transmission rod 104. A rotary joint 208 is fixedly connected to the top of the connecting pipe 207. The connecting pipe 207 is fixedly connected to the spray pipes 205, so that the externally transported desulfurization liquid can continuously enter the interior of the spray pipes 205 during the rotation of the spray hood 203.

[0036] When the drive motor 102 is working, it drives the transmission rod 104 to rotate through the transmission gear 103 and the driven gear 105. The transmission rod 104 further drives the spray hood 203 and the spray pipe 205 to rotate synchronously, so that the desulfurization liquid sprayed from the atomizing nozzle 206 forms a rotating spray state. At the same time, the rising flue gas enters the spraying area through the first vent 202 in sequence. Under the action of the rotation of the spray hood 203, it forms a ring vortex, which makes the flue gas and the desulfurization liquid droplets come into full contact, thereby improving the absorption efficiency of acidic gases in the flue gas.

[0037] The support plate 201 is equipped with a discharge component 209, which allows the desulfurization liquid collected at the top of the support plate 201 to be reintroduced into the lower area for recycling.

[0038] The discharge assembly 209 includes a discharge pipe 209a fixedly connected to the outer side of the top of the support plate 201. Several discharge pipes 209a are arranged in a ring at equal intervals, and a second one-way valve 209b is fixedly connected to the bottom of each discharge pipe 209a. During spraying, some of the desulfurization liquid that has not fully participated in the reaction drips onto the top of the support plate 201. The top of the support plate 201 is shaped like an inverted V, causing the desulfurization liquid to flow outwards under gravity and enter the discharge pipes 209a. It then flows through the second one-way valve 209b to the lower support tank 301 area. Because this portion of the desulfurization liquid retains high desulfurization activity, it can be reused in subsequent dust removal processes, achieving secondary utilization of the desulfurization liquid and improving the utilization rate of the desulfurizing agent.

[0039] The transmission rod 104 is equipped with an exhaust assembly 210. This structure allows for the periodic adjustment of the opening and closing of the exhaust pipe 210g according to the rotation state of the transmission rod 104, thereby increasing the residence time of the flue gas.

[0040] The exhaust assembly 210 includes a retaining ring 210a movably connected to the top of the surface of the transmission rod 104. Guide protrusions 210b are fixedly connected to the front and rear sides of the top of the retaining ring 210a. Extrusion rods 210c are fixedly connected to both sides of the surface of the transmission rod 104. A connecting bracket 210d is fixedly connected to the surface of the retaining ring 210a. A first spring 210e is fixedly connected to the bottom of the connecting bracket 210d. A connecting plate is fixedly connected to the bottom of the first spring 210e. 210f, the outer side of the connecting plate 210f is fixedly connected to the inner wall of the desulfurization tank 100, the top of the desulfurization tank 100 is fixedly connected to the exhaust pipe 210g, the exhaust pipe 210g is fixedly connected to the venting plate 210h, the top of the connecting frame 210d extends through to the top of the venting plate 210h and is fixedly connected to the sealing plate 210j, the top of the venting plate 210h is fixedly connected to the tension spring 210i, and the top of the tension spring 210i is fixedly connected to the sealing plate 210j.

[0041] When the transmission rod 104 rotates, the extrusion rod 210c periodically pushes the movable sleeve 211 along the guide protrusion 210b, causing the connecting frame 210d to drive the sealing disc 210j to move up and down. This allows the sealing disc 210j and the venting disc 210h to intermittently open the exhaust pipe 210g. The flue gas stays inside the desulfurization tank 100 for a certain period of time before being discharged, further improving the desulfurization reaction time and purification efficiency.

[0042] The top of the cross-section of the bearing plate 201 is set in an inverted V shape, and the bottom of the inner wall of the cross-section of the spray hood 203 is set in a V shape. The two work together to converge and guide the flue gas, so that the flue gas forms an upward rotating spiral airflow in the spraying area, thereby increasing the contact area between the flue gas and the desulfurization liquid.

[0043] Example 2

[0044] Based on Example 1, a stirring dust removal mechanism 300 for gas dust removal is movably connected to the bottom of the desulfurization tank 100. This structure allows the flue gas entering the desulfurization tank 100 to undergo liquid dust removal treatment first, and pre-desulfurize using the desulfurization liquid recovered by the spraying desulfurization mechanism 200, thereby reducing the dust concentration and acid gas concentration entering the upper desulfurization area.

[0045] The stirring and dust removal mechanism 300 includes a support pool 301 movably connected to the bottom of the desulfurization tank 100. The support pool 301 is used to store desulfurization liquid and desulfurization liquid recovered by the discharge component 209. A rotating disk 302 is provided on the top of the support pool 301. The bottom end of the transmission rod 104 is fixedly connected to the top of the rotating disk 302, so that the rotating disk 302 can be driven to rotate synchronously when the transmission rod 104 rotates. A stirring rod 303 is fixedly connected to the bottom of the rotating disk 302. Several stirring rods 303 are provided and are distributed in a ring at equal intervals.

[0046] When the transmission rod 104 rotates, the rotating disk 302 drives multiple stirring rods 303 to rotate synchronously, continuously stirring the liquid inside the carrying tank 301, so that the liquid forms a circulating flow state, avoiding long-term accumulation of sediment, and improving the contact efficiency between flue gas and liquid.

[0047] A vent pipe 304 is fixedly connected inside the support tank 301. Several vent pipes 304 are arranged in a ring at equal intervals, and a first one-way valve 305 is fixedly connected to the top of each vent pipe 304. After the flue gas enters the area of ​​the support tank 301, it enters the liquid through the vent pipes 304 and the first one-way valve 305, forming a large number of bubbles. Under the disturbance of the stirring rod 303, the bubbles are further dispersed, thereby increasing the contact area between the flue gas and the liquid, so that the dust particles in the flue gas are adsorbed and captured by the liquid.

[0048] Meanwhile, the desulfurization liquid recovered by the emission component 209 continues to enter the carrier pool 301. This part of the desulfurization liquid still has high desulfurization activity. When the flue gas passes through the liquid in the form of bubbles, the acidic gas in the flue gas can continue to react with the recovered desulfurization liquid, thereby realizing the simultaneous operation of dust removal and secondary desulfurization and improving the utilization rate of desulfurization liquid.

[0049] The carrying tank 301 is equipped with a discharge component 306, which is used to automatically discharge part of the waste liquid and deposited impurities according to the change in the weight of the liquid inside the carrying tank 301.

[0050] The discharge assembly 306 includes a discharge pipe 306a fixedly connected inside the carrying tank 301, with a connecting cover 306b connected to the bottom of the discharge pipe 306a; a sealing frame 306c is movably connected to both sides inside the connecting cover 306b; a guide groove 306d is opened inside the sealing frame 306c; a fixed rod 306e is movably connected to the bottom inside the guide groove 306d; the outer end of the fixed rod 306e is fixedly connected to the inner wall of the desulfurization tank 100; a filter screen 306f is fixedly connected to the bottom inside the connecting cover 306b; the sealing frame 306c is connected to the filter screen 306f; a connecting pipe 306g is fixedly connected to the bottom of the connecting cover 306b; a telescopic hose 306h is fixedly connected to the bottom of the connecting pipe 306g; and a drain pipe 306i is fixedly connected to the bottom of the telescopic hose 306h.

[0051] A second spring 307 is fixedly connected to the outer side of the bottom of the carrying pool 301. Several second springs 307 are provided and are distributed in a ring at equal intervals. A connecting block 308 is fixedly connected to the bottom end of the second spring 307. The connecting block 308 is fixedly connected to the inner wall of the desulfurization tank 100.

[0052] During equipment operation, the desulfurization liquid recovered from the spraying area continuously enters the carrying tank 301, causing the liquid inside the carrying tank 301 to gradually increase, and the overall weight of the carrying tank 301 to increase accordingly. When the weight increases to a set level, the carrying tank 301 moves downward and compresses the second spring 307. The carrying tank 301 drives the discharge component 306 to move downward synchronously, while the fixed rod 306e remains relatively stationary. At this time, the sealing frame 306c slides relative to the guide groove 306d and opens to both sides, thereby opening the discharge channel inside the connecting cover 306b.

[0053] After the discharge channel is opened, some liquid and sediment impurities inside the carrying tank 301 enter the connecting cover 306b through the discharge pipe 306a. The impurities are intercepted by the filter screen 306f, while the liquid is discharged through the connecting pipe 306g, the telescopic hose 306h, and the drain pipe 306i. When the discharged liquid reaches a certain amount, the overall weight of the carrying tank 301 is reduced, the second spring 307 gradually rebounds and resets, and drives the carrying tank 301 and the discharge assembly 306 to move upward. The sealing frame 306c then closes the discharge channel again, thereby stopping the discharge.

[0054] The cross-section of the carrying tank 301 is V-shaped, and the bottom of the cross-section of the rotating disk 302 is also V-shaped. The combination of the two can cause the sediment at the bottom of the tank to converge towards the central area. At the same time, under the action of the stirring rod 303, an upward rolling circulating flow field is formed, which further improves the contact time between flue gas and liquid and the dust removal and desulfurization effect.

[0055] Working principle: In use, first add an appropriate amount of desulfurization liquid into the carrying tank 301, and simultaneously supply desulfurization liquid to the rotary joint 208, then start the drive motor 102. After the drive motor 102 starts running, it drives the transmission gear 103 to rotate. The transmission gear 103 drives the transmission rod 104 to rotate synchronously through the driven gear 105. During the rotation of the transmission rod 104, it also drives the spray hood 203, the rotating disk 302, the stirring rod 303, and the extrusion rod 210c to rotate synchronously.

[0056] The flue gas to be treated enters the desulfurization tank 100 through the gas transmission pipe 101 and then flows into the ventilation pipe 304. It then flows upwards along the ventilation pipe 304 to the first one-way valve 305. Under gas pressure, the first one-way valve 305 opens, allowing the flue gas to flow through it and into the liquid inside the support tank 301, forming a large number of bubbles. Simultaneously, the rotating disk 302 drives the stirring rod 303 to rotate continuously, causing the liquid inside the support tank 301 to churn and circulate. The bubbles formed by the flue gas are continuously dispersed in the desulfurization liquid, increasing the contact area between the flue gas and the liquid. The liquid adsorbs and captures dust particles in the flue gas, causing the dust to gradually settle to the bottom of the support tank 301. This process simultaneously performs preliminary desulfurization, achieving initial dust removal and desulfurization treatment of the flue gas.

[0057] After preliminary dust removal and desulfurization, the flue gas continues to flow upwards and enters the desulfurization zone formed between the support plate 201 and the spray hood 203 through the first vent 202 on the support plate 201. Simultaneously, the desulfurization liquid enters the connecting pipe 207 through the rotary joint 208, and is then transported to each spray pipe 205 through the connecting pipe 207, finally being sprayed out through the atomizing nozzle 206 to form fine droplets. Due to the continuous rotation of the spray hood 203, the sprayed desulfurization liquid forms a ring-shaped rotating mist curtain under centrifugal force.

[0058] After entering the desulfurization zone, the flue gas converges towards the central area under the combined guiding effect of the inverted V-shaped structure at the top of the support plate 201 and the V-shaped structure at the bottom of the spray hood 203, forming a spiral upward airflow as the spray hood 203 rotates. The spirally flowing flue gas comes into full contact with the rotating sprayed desulfurization liquid, allowing the sulfur dioxide and other acidic gases in the flue gas to be absorbed by the desulfurization liquid, thus completing the secondary desulfurization treatment.

[0059] During the desulfurization process, some of the desulfurization liquid drips downwards after completing the reaction, while some of the desulfurization liquid that has not fully participated in the reaction falls to the top of the support plate 201. Because the top of the support plate 201 is designed in an inverted V shape, the liquid flows outwards along the surface of the support plate 201 and enters the discharge pipe 209a, then flows downwards through the second one-way valve 209b back into the support tank 301. The desulfurization liquid returning to the support tank 301 continues to contact the flue gas, allowing its remaining desulfurization capacity to be reused, thereby improving the utilization rate of the desulfurization liquid.

[0060] After desulfurization, the gas enters the interior of the spray hood 203 and is discharged to the outer area of ​​the spray hood 203 through the second vent 204, and then continues to flow into the top space of the desulfurization tank 100.

[0061] As the transmission rod 104 continues to rotate, the pressing rod 210c drives the movable sleeve 211 to rotate synchronously. When the movable sleeve 211 rotates to the position of the guide protrusion 210b, the movable sleeve 211 contacts the guide protrusion 210b and, under the guidance of the guide protrusion 210b, generates axial displacement along the surface of the pressing rod 210c, thereby pushing the fixed ring 210a and the connecting frame 210d to move downward, while compressing the first spring 210e.

[0062] When the connecting frame 210d descends, it drives the sealing plate 210j to move downward and seal with the venting plate 210h, descending synchronously. As the movable sleeve 211 continues to contact the guide protrusion 210b, the sealing plate 210j can move up and down reciprocally. When the sealing plate 210j moves upward, the tension spring 210i is stretched, so that the gas can form an exhaust gap inside the exhaust pipe 210g and be discharged to the outside of the desulfurization tank 100 through the exhaust pipe 210g.

[0063] Meanwhile, the discharge pipe 209a continuously transports the unreacted desulfurization liquid into the carrier tank 301. As the recovered liquid accumulates, the liquid level inside the carrier tank 301 gradually rises, the overall weight of the carrier tank 301 increases, and the second spring 307 is gradually compressed. When the carrier tank 301 descends to the set position, the carrier tank 301 moves the discharge pipe 306a and the connecting cover 306b downwards as a whole, while the fixed rod 306e remains stationary. Under the guidance of the guide groove 306d, the sealing frame 306c slides relative to the fixed rod 306e and gradually opens to both sides, so that the discharge pipe 306a and the interior of the connecting cover 306b are connected.

[0064] At this time, some waste liquid and sediment impurities inside the carrying tank 301 enter the discharge pipe 306a and fall into the connecting cover 306b. After being filtered by the filter screen 306f, the liquid is discharged through the connecting pipe 306g, the telescopic hose 306h and the drain pipe 306i. The filter screen 306f can filter the discharged liquid.

[0065] As liquid is continuously discharged, the overall weight of the support tank 301 gradually decreases, and the second spring 307 gradually rebounds and resets, causing the support tank 301, the drain pipe 306a, and the connecting cover 306b to rise again. During the rise of the connecting cover 306b, the sealing frame 306c moves in the opposite direction along the guide chute 306d and recloses the drain channel. At the same time, it can push the impurities on the filter screen 306f inward and pile them inside the filter screen 306f, thereby stopping the discharge and keeping the liquid level inside the support tank 301 within a reasonable range.

[0066] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
