Description

Technical Field

[0001] This utility model relates to the technical field of desulfurization and dust removal devices, and more specifically, to a jet pressure compensated dynamic wave desulfurization and dust removal device. Background Technology

[0002] Sintering kilns are key industrial equipment used for high-temperature processing of materials, enabling them to achieve densification or specific properties through sintering (interparticle diffusion bonding). Sintering involves heating powder or green bodies to high temperatures (usually below the melting point), causing neck connections to form between particles through diffusion, flow, and other mechanisms, ultimately densifying the material or forming the desired properties. This process is widely used in ceramics, metals, refractory materials, and other materials.

[0003] Existing sintering kilns with high sulfur and dust flue gas mostly use empty tower spray desulfurization methods. The equipment is large and expensive. Because the empty tower spray equipment is tall, the required spray coverage area, liquid-to-gas ratio and water pump head are very high, resulting in a large waste of electricity. The manufacturing, operation and maintenance costs are also relatively high. Summary of the Invention

[0004] To address the problems existing in the prior art, the purpose of this utility model is to provide a jet pressure-compensated dynamic wave desulfurization and dust removal device. This device guides the introduced water and sulfur-containing gas-water mixture through a Venturi mixing nozzle, imparting forward kinetic energy to the flue gas and offsetting some of the resistance caused by the reverse jet of the dynamic wave. This keeps the equipment's wind resistance within a small range, while eliminating the risk of scaling and clogging of the nozzle pipeline. The mixture settles in the settling chamber and is then dehydrated by a high-efficiency baffle demister and a cyclone demister, completing the desulfurization and dust removal operation. The device boasts high desulfurization and dust removal efficiency, is small in size, has a simple structure, requires fewer auxiliary equipment, and significantly reduces equipment costs compared to spray towers.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. Example

[0020] Please see Figure 1-3 A jet pressure compensated dynamic wave desulfurization and dust removal device includes: a settling chamber 1, a reverse spray pipe 2 fixedly connected to the top surface of the settling chamber 1, and an outlet pipe 13 fixedly connected to the top surface of the settling chamber 1; and a desulfurization and dust removal component, which includes: a desulfurization injection component, a jet mixing component, a flushing component, and a demisting component. The desulfurization injection component is disposed between the inner walls of the reverse spray pipe 2 to mix waste and desulfurization liquid. The jet mixing component is disposed between the inner walls of the reverse spray pipe 2 to extract the mixture in the foam zone and spray it out. The flushing component is disposed between the inner walls of the outlet pipe 13 to flush the gas. The demisting component is disposed between the inner walls of the outlet pipe 13 to demist the gas.

[0021] In a specific embodiment of this utility model, sulfur-containing gas is introduced through the reverse nozzle 2, followed by desulfurization liquid through the water inlet pipe 5, and then sulfur-containing gas is drawn in through the gas outlet pipe 13. The gas is then distributed and sprayed out through the water distributor 6 and multiple water nozzles 7. The sulfur-containing gas and the sprayed desulfurizing agent violently impact each other in the opposite direction, resulting in a large contact surface area between the gas and liquid phases at the interface and a rapid interface renewal rate, thus achieving a highly efficient mass transfer process. Most sulfides and dust are removed. The flue gas then passes through the foam zone and continues downward with the falling desulfurizing agent, entering the jet mixing component. Water is introduced through the jet pipe 8 and then sprayed out by the jet distributor 9 and multiple Venturi mixing nozzles 10. The Venturi mixing nozzles 10 guide the introduced water and the sulfur-containing gas-water mixture, imparting a suitable mass transfer effect to the flue gas. The large forward kinetic energy of the air partially offsets the resistance caused by the reverse jet of the kinetic wave, keeping the equipment's wind resistance within a small range. The mixture of desulfurizing agent droplets and flue gas continues to descend and enters the settling chamber 1. At this point, the cross-sectional area increases, the flow velocity decreases, and the internal pressure of the fluid increases. The steam-water mixture diffuses outward, and the desulfurizing liquid forms larger water droplets carrying larger particles. Under the action of gravity, these droplets fall to the bottom of the equipment. The desulfurized flue gas and water vapor carry smaller droplets into the larger gravity settling section with the opposite flow direction. The water droplets carry tiny dust particles downward, while the flue gas rises. The equipment is then dehydrated by the high-efficiency baffle demister 14 and the cyclone demister 16, completing the desulfurization and dust removal operation. The equipment has high desulfurization and dust removal efficiency, is small in size, has a simple structure, and requires fewer auxiliary equipment. Compared with a spray tower, the equipment cost is significantly reduced.

[0022] Specifically, the desulfurization injection assembly includes: an air inlet pipe 4, a water inlet pipe 5, a water inlet distributor 6, and multiple water inlet nozzles 7. The water inlet pipe 5 is installed on the reverse spray pipe 2, the air inlet pipe 4 is installed on the water inlet pipe 5, and the air inlet pipe 4 and the water inlet pipe 5 are connected. The water inlet distributor 6 is installed at one end of the water inlet pipe 5, and the multiple water inlet nozzles 7 are all installed at the output end of the water inlet distributor 6.

[0023] In this embodiment, desulfurization liquid is introduced through water inlet pipe 5, air inlet pipe 4 is inserted into water inlet pipe 5 and the cross-section of water inlet pipe 5 is reduced. At the same time, air inlet pipe 4 will extract part of the introduced waste gas and mix the waste gas with desulfurization liquid to form foam. Water inlet distributor 6 and multiple water inlet nozzles 7 spray out the mixture. The sulfur-containing gas and the sprayed desulfurizing agent violently impact each other in the opposite direction to improve the contact effect.

[0024] Specifically, the jet mixing assembly includes a jet pipe 8, a jet distributor 9, and multiple Venturi mixing nozzles 10. The jet pipe 8 is mounted on the reverse nozzle 2, the jet distributor 9 is mounted on one end of the jet pipe 8, and the multiple Venturi mixing nozzles 10 are all mounted on the output end of the jet distributor 9.

[0025] In this embodiment, the jet liquid is introduced through the jet pipe 8, and guided and ejected by the jet distributor 9 and multiple Venturi mixing nozzles 10. The Venturi mixing nozzles 10 are designed and manufactured based on the Bernoulli jet attraction principle, which has a very good mixing effect and a very large ejection force. The Venturi mixing nozzles 10 guide the introduced water and sulfur-containing gas-water mixture by spraying out the jet liquid and simultaneously drawing in the falling mixture, giving the flue gas a large forward kinetic energy, offsetting part of the resistance caused by the reverse jet of the kinetic wave, and keeping the equipment wind resistance within a small range.

[0026] Specifically, the flushing assembly includes: an external inlet pipe, a defogger backwasher 15, and a defogger forward flusher 16. The external inlet pipe is installed on one side of the outer wall of the air outlet pipe 13. The defogger backwasher 15 is installed between the inner walls of the air outlet pipe 13 and is connected to the external inlet pipe. The defogger forward flusher 16 is installed between the inner walls of the air outlet pipe 13 and is connected to the external inlet pipe.

[0027] In this embodiment, a demisting backwasher 15 and a demisting forward washer 16 are installed through an external inlet pipe. The demisting backwasher 15 and the demisting forward washer 16 repeatedly wash the settled flue gas to improve the desulfurization effect.

[0028] Specifically, the demisting assembly includes a swirl demister 12 and a baffle demister 14. The swirl demister 12 is installed between the inner walls of the outlet pipe 13, and the baffle demister 14 is installed between the inner walls of the outlet pipe 13.

[0029] In this embodiment, the discharged liquid is dehydrated by the cyclone demister 12 and the baffle demister 14 to meet the discharge requirements.

[0030] Specifically, a partition plate 11 is fixedly connected to the inner top surface of the settling chamber 1, and an inlet 3 is provided on the top surface of the reverse nozzle 2. An air inlet is provided on one side of the inlet 3, and the air inlet and the air inlet pipe 4 are matched.

[0031] In this embodiment, the settling chamber 1 is divided by the partition 11, so that the settling chamber 1 is divided into a separation settling section and a gravity settling section.

[0032] Working principle: Sulfur-containing gas is introduced through the reverse nozzle 2, followed by desulfurization liquid through the water inlet pipe 5, and then sucked in through the gas outlet pipe 13. The gas is then distributed and sprayed out through the water distributor 6 and multiple water nozzles 7. The sulfur-containing gas and the sprayed desulfurizing agent violently impact each other in the opposite direction, resulting in a large contact surface area and rapid interface renewal at the gas-liquid interface, thus achieving a highly efficient mass transfer process. Most sulfides and dust are removed. The flue gas then passes through the foam zone and continues downward with the falling desulfurizing agent, entering the jet mixing component. Water is introduced through the jet pipe 8 and then sprayed out by the jet distributor 9 and multiple Venturi mixing nozzles 10. The Venturi mixing nozzles 10 guide the introduced water and the sulfur-containing gas-water mixture, imparting a large mass transfer effect to the flue gas. The forward kinetic energy offsets some of the resistance caused by the reverse jet of the kinetic wave, keeping the equipment's wind resistance within a small range. The mixture of desulfurizing agent droplets and flue gas continues to descend and enters the settling chamber 1. At this point, the cross-sectional area increases, the flow velocity decreases, and the internal pressure of the fluid increases. The steam-water mixture diffuses outward, and the desulfurizing liquid forms larger water droplets carrying larger particles. Under the action of gravity, these droplets fall to the bottom of the equipment. The desulfurized flue gas and water vapor carry smaller droplets into the larger gravity settling section with the opposite flow direction. The water droplets carry tiny dust particles downward, while the flue gas rises. The equipment is then dehydrated by the high-efficiency baffle demister 14 and the cyclone demister 16, completing the desulfurization and dust removal operation. The equipment has high desulfurization and dust removal efficiency, is small in size, has a simple structure, and requires fewer auxiliary equipment. Compared with a spray tower, the equipment cost is significantly reduced.

The wiring diagram of the power element and the supply of power are common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and wiring layout will not be explained in detail.
