Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of flue gas treatment devices, specifically an integrated device for flue gas condensation, dust removal, and desulfurization. Background Technology
[0002] In recent years, with the country's increasing environmental protection requirements, there have been stricter requirements for pollution emissions in production, with air pollution being the most serious concern. For example, the flue gas produced by the combustion of coal in factories needs to be desulfurized and dust removed before it can be emitted. Although the pollutants in the flue gas after desulfurization and dust removal meet the requirements, it still causes pollution to the environment. In the face of severe environmental conditions, it is necessary to continuously improve the flue gas treatment technology in industrial production to meet the increasingly stringent flue gas emission requirements.
[0003] The patent with publication number CN205832944U discloses an integrated device for desulfurization and dust removal of boiler flue gas, including a flue gas processor, a flue gas inlet pipe connected to the flue gas processor, and an induced draft fan installed at the flue gas outlet of the flue gas processor. The flue gas processor is provided with a filter component, a spray component, and a separation component that plays the role of isolating and separating flue gas from top to bottom. The separation component includes a grid layer and a tubular layer. The tubular layer is located above the grid layer and is installed in the flue gas processor. The grid layer is located above the flue gas inlet pipe.
[0004] In this integrated flue gas desulfurization and dust removal device, the flue gas is cooled and dust is removed by the spray assembly. However, the spray head position is fixed, which means that some areas cannot be covered during the spraying process, resulting in uneven and incomplete spraying and insufficient cooling and dust removal effect on the flue gas. In order to address the above problems, this application designs an integrated flue gas condensation, dust removal and desulfurization device. Utility Model Content
[0005] (a) Technical problems to be solved
[0006] To address the shortcomings of existing technologies, this utility model provides an integrated device for flue gas condensation, dust removal, and desulfurization.
[0007] (II) Technical Solution

The water supply pump is located on one side of the treatment tower. A wastewater tank is located near the bottom of the treatment tower. A sewage pipe is connected to the wastewater tank on the treatment tower. An inlet pipe is connected to the treatment tower above the wastewater tank. A water spraying mechanism for flue gas condensation and dust removal is installed inside the treatment tower. The water spraying mechanism includes a structural beam fixed inside the treatment tower. A water inlet pipe is fixed to the bottom of the structural beam. The water inlet pipe passes through the treatment tower and connects to the water supply pump. A water-use rotary joint is installed on the water inlet pipe. The bottom of the water-use rotary joint... A rotating block is fixed, and the rotating block is connected to the water rotary joint. Multiple connecting pipes are connected to the outer wall of the rotating block, and water mist nozzles are connected to the connecting pipes. A stabilizing rotating ring is fixed to the outer wall of the multiple water mist nozzles, and the stabilizing rotating ring is slidably connected to the inner wall of the treatment tower. An annular toothed rail is fixed to the outer wall of the rotating block near the top. A motor is installed at the bottom of the structural beam, and a gear is fixed downward at the output end of the motor. The gear meshes with the annular toothed rail.

Multiple leakage holes are opened at the bottom of the desulfurization container, and the desulfurization container contains desulfurization adsorbent. A flue gas outlet pipe is connected to the top of the treatment tower.
[0009] To make the water mist nozzle rotate more smoothly with the stabilizing rotating ring, the present invention is improved by having multiple rollers rotatably connected to the outer wall of the stabilizing rotating ring, and the rollers contacting the inner wall of the treatment tower.
[0010] In order to enable the flue gas to be discharged quickly and in a concentrated manner, the present invention is improved by setting the inner top wall of the treatment tower as a conical surface.
[0011] To prevent rainwater from entering the device at the smoke outlet pipe, this utility model is improved by fixing a rain cover to the top of the smoke outlet pipe.
[0012] In order to enable real-time control of the sewage discharge rate, the present invention is improved by installing a control valve on the sewage discharge pipe.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Please see Figure 1-4An integrated flue gas condensation, dust removal, and desulfurization device includes a treatment tower 1 and a water supply pump 2. The water supply pump 2 is located on one side of the treatment tower 1. A wastewater tank 3 is located near the bottom of the treatment tower 1. A sewage pipe 4 is connected to the wastewater tank 3 on the treatment tower 1. An inlet pipe 5 is connected to the treatment tower 1 above the wastewater tank 3. A water spraying mechanism for flue gas condensation and dust removal is installed inside the treatment tower 1. The water spraying mechanism includes a structural beam 6, which is fixed inside the treatment tower 1. A water inlet pipe 7 is fixed to the bottom of the structural beam 6. The water inlet pipe 7 passes through the treatment tower 1 and connects to the water supply pump 2. A water-use rotary joint 8 is installed on the water inlet pipe 7. A rotating block 9 is fixed to the bottom of the water-use rotary joint 8. The rotating block 9 interacts with the water-use rotary joint 8. The adapter 8 is connected, and multiple connecting pipes 10 are connected to the outer wall of the rotating block 9. Water mist nozzles 11 are connected to the connecting pipes 10. A stabilizing rotating ring 12 is fixed to the outer wall of the multiple water mist nozzles 11. The stabilizing rotating ring 12 is slidably connected to the inner wall of the treatment tower 1. An annular toothed rail 13 is fixed to the top of the outer wall of the rotating block 9. A motor 14 is installed at the bottom of the structural beam 6. A gear 15 is fixed downward at the output end of the motor 14. The gear 15 meshes with the annular toothed rail 13. A desulfurization container 16 is fixed inside the treatment tower 1 above the water spraying mechanism. Multiple leakage holes 17 are opened at the bottom of the desulfurization container 16. The desulfurization container 16 contains desulfurization adsorbent. A flue gas outlet pipe 18 is connected to the top of the treatment tower 1.
[0024] When this device is in use, flue gas enters the treatment tower 1 through the flue gas inlet pipe 5. Simultaneously, the water supply pump 2 is activated to connect with an external water supply system, delivering water to the water inlet pipe 7. The water then passes sequentially through the water inlet pipe 7, the water-using rotary joint 8, the rotating block 9, and the connecting pipe 10 to the water mist nozzles 11. Water mist is then sprayed out through the nozzles. Simultaneously, the motor 14 is activated, driving the gear 15. The gear 15 meshes with the annular gear rail 13, thereby rotating the rotating block 9. The rotating block 9 then rotates the connecting pipe 10 and the multiple water mist nozzles 11. At this time, the water-using rotary joint 8... The water mist nozzle 11 rotates without affecting the water delivery, spraying water mist while rotating to fully and evenly cover the cross-section of the treatment tower 1. At this time, the flue gas entering the treatment tower 1 floats upward and comes into full contact with the falling water mist, cooling and removing dust from the flue gas. After dust removal, the water mist absorbs dust particles and falls into the wastewater tank 3 for centralized discharge. Meanwhile, the flue gas continues to float upward and comes into full contact with the desulfurization adsorbent inside the desulfurization container 16 through the leakage hole 17, performing desulfurization and dust absorption treatment on the flue gas, and is discharged through the flue gas outlet pipe 18.
[0025] In actual use, it was found that when the stabilizing ring 12 rotates inside the processing tower 1, it does not rotate smoothly due to the influence of friction. In order to solve the above problem, in this embodiment, a plurality of rollers 19 are rotatably connected to the outer wall of the stabilizing ring 12, and the rollers 19 are in contact with the inner wall of the processing tower 1.
[0026] In actual use, it was found that in order to quickly and centrally discharge the flue gas, the inner top wall of the treatment tower 1 in this embodiment is set as a conical surface.
[0027] In actual use, it was found that rainwater would enter the device at the smoke outlet pipe 18. To avoid the above problem, in this embodiment, a rain cover 20 is fixed to the top of the smoke outlet pipe 18.
[0028] In actual use, it was found that in order to control the sewage discharge rate in real time, a control valve 21 is installed on the sewage pipe 4 in this embodiment.
[0029] In actual use, it was found that the sulfides in the flue gas come into contact with the inner wall of the treatment tower 1, and after a long time, they cause strong corrosive damage. In order to avoid the above problems, in this embodiment, the inner wall of the treatment tower 1 is provided with an anti-corrosion coating.
