Description

Technical Field

[0001] This utility model relates to the field of flue gas purification technology, and in particular to a device for rapid cooling and deacidification of waste gas. Background Technology

[0002] As my country's comprehensive national strength continues to improve, the amount of waste generated is also increasing day by day. During the waste incineration process, the fuel contains elements such as sulfur and nitrogen, which produce harmful acidic gases such as SO2, NOx and HCl through chemical reactions. When these gases are released into the atmosphere, they interact with water vapor and oxygen to form strong acidic substances such as sulfuric acid, nitric acid and hydrochloric acid, causing environmental problems such as acid rain.

[0003] In existing technologies, a water pump is required when adding alkaline solution to a tank to pump the solution into the tank. The water pump usually requires an additional motor drive, which increases the overall energy consumption of the system. The flow control of the water pump depends on the adjustment of the motor speed, and changes in motor speed may lead to unstable flow. Pressure fluctuations in the water pump may cause pulsation during liquid delivery, resulting in uneven liquid flow rate and spray effect. To address this, we propose a waste gas rapid cooling deacidification device. Utility Model Content

[0004] The purpose of this invention is to provide a waste gas rapid cooling and deacidification device to solve the problems mentioned in the background art, which require the use of a water pump when adding alkaline solution to the tank. The water pump usually requires an additional motor drive, which increases the energy consumption of the overall system. The flow control of the water pump depends on the adjustment of the motor speed, and the change in motor speed may lead to unstable flow. The pressure fluctuation of the water pump may cause pulsation in the liquid delivery process, resulting in uneven liquid flow rate and spray effect.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a waste gas rapid cooling and deacidification device, comprising a support frame, a deacidification structure, a spray structure, and a filter structure. The spray structure is disposed within the deacidification structure, and the filter structure is disposed at the bottom of the deacidification structure. The spray structure includes a fixed cylinder and a fixed frame. The fixed cylinder is mounted with a pull rod via a piston. A fixed wheel is fixedly mounted on a fixed plate at the end of the pull rod away from the piston. A spring is fitted on the pull rod. The fixed cylinder is connected to a storage tank via a conduit. The fixed cylinder is connected to the interior of the tank via a connecting pipe. An atomizing nozzle is fixedly mounted at the end of the connecting pipe away from the fixed cylinder. One-way valves are fixedly mounted on the conduit and the connecting pipe, respectively.

[0006] As a preferred embodiment, the deacidification structure includes a box body, a support column, and a liquid storage tank. The box body is fixedly installed on the support frame, and the liquid storage tank is fixedly installed on the top of the box body via the support column.

[0007] As a preferred embodiment, a motor is fixedly installed at the bottom of the storage tank, a rotating shaft is fixedly connected to the motor shaft, a stirring blade is fixedly installed on the rotating shaft, a cam is fixedly installed at the upper end of the rotating shaft, a control valve is fixedly installed at the bottom of the tank, and an inlet pipe is fixedly connected to the side wall of the tank.

[0008] As a preferred embodiment, the fixed cylinder is fixedly installed on the top of the housing by a fixing bracket, the piston is slidably installed inside the fixed cylinder, the pull rod is fixedly installed on one end of the piston, the end of the pull rod away from the piston extends through the side wall of the fixed cylinder to the outside of the fixed cylinder, and the pull rod is slidably connected to the side wall of the fixed cylinder.

[0009] As a preferred embodiment, one end of the spring is fixedly connected to the fixed plate, and the other end of the spring is fixedly connected to the fixed cylinder. The atomizing nozzle is located inside the housing. A one-way valve on the conduit ensures that the liquid in the storage tank can only flow into the fixed cylinder through the conduit, and a one-way valve on the connecting pipe ensures that the liquid in the fixed cylinder can only flow into the housing through the connecting pipe.

[0010] As a preferred embodiment, the filter structure includes a filter box, which is fixedly installed at the bottom of the box body. A slide rail is fixedly installed on the inner wall of the filter box. The slide rail slides a filter plate through a slide bar. A sealing plate is fixedly installed at one end of the filter plate, and a handle is fixedly installed on the side of the sealing plate away from the filter plate.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] 1. In the spray structure, when the motor drives the stirring blades to agitate the tank through the rotating shaft, it will drive the cam to rotate. When the cam contacts the fixed wheel, it compresses the spring. At the same time, the fixed wheel drives the piston to slide in the fixed cylinder through the fixed plate and the pull rod. When the cam moves away from the fixed wheel, the spring returns to its original position, causing the piston to return to its original position. This causes the piston to move back and forth in the fixed cylinder, thereby continuously transporting the alkaline solution in the storage tank to the atomizing nozzle and then spraying it out. The stirring blades fully mix the waste gas and alkaline solution, reducing the dependence on the external pump system, reducing the complexity of the equipment and maintenance costs. The reciprocating motion of the piston stabilizes the speed at which the alkaline solution is transported to the atomizing nozzle, thereby improving the atomization effect of the nozzle. The motor-driven single system can complete the stirring and alkaline solution transportation at the same time, optimizing the energy utilization rate.

[0013] 2. Through the set filtration structure, the filter plate filters the gas and solids produced after the reaction. After the filter plate has been filtering for a long time, it can be pulled out of the filter box for cleaning or replacement. This can prevent solid particles from entering the subsequent treatment process or being emitted into the environment, thereby improving the efficiency of the overall waste gas treatment system. When a large amount of impurities accumulate on the filter plate, a new filter plate can be quickly replaced to ensure the continuous and efficient operation of the system. The technical requirements for daily operators are low, which improves the operability of the equipment. Attached Figure Description

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. Example 1

[0022] Please see the appendix Figure 1 - Appendix Figure 4The waste gas rapid cooling and deacidification device includes a support frame 1, a deacidification structure 2, a spray structure 3, and a filter structure 4. The deacidification structure 2 is fixedly installed on the support frame 1, the spray structure 3 is installed on the deacidification structure 2, and the filter structure 4 is installed at the bottom of the deacidification structure 2. The deacidification structure 2 includes a housing 21, a support column 22, and a liquid storage tank 23. The housing 21 is fixedly installed on the support frame 1, and the liquid storage tank 23 is fixedly installed at the top of the housing 21 via the support column 22. The liquid storage tank 23 stores alkaline liquid, and the bottom of the liquid storage tank 23 is fixed. A motor 24 is installed, and a rotating shaft 25 is fixedly connected to the motor shaft of the motor 24. The rotating shaft 25 extends through the top wall of the housing 21 and into the housing 21. The rotating shaft 25 is rotatably connected to the top wall of the housing 21. An agitator 26 is fixedly installed on the rotating shaft 25 inside the housing 21. A cam 27 is fixedly installed on the rotating shaft 25 and at the upper end of the top wall of the housing 21. A control valve 28 is fixedly installed at the bottom end of the housing 21. An inlet pipe 29 is fixedly connected to the side wall of the housing 21 and is interconnected with the interior of the housing 21.

[0023] The spray structure 3 includes a fixed cylinder 301 and a fixed frame 302. The fixed cylinders 301 are fixedly installed on the top of the housing 21 via the fixed frame 302. The number of fixed cylinders 301 is set to three. A piston 304 is slidably installed inside the fixed cylinder 301. A pull rod 303 is fixedly installed on one end of the piston 304. The end of the pull rod 303 away from the piston 304 extends through the side wall of the fixed cylinder 301 to the outside of the fixed cylinder 301, and the pull rod 303 is slidably connected to the side wall of the fixed cylinder 301. A fixed wheel 306 is fixedly installed on the end of the pull rod 303 away from the piston 304 via a fixed plate 305. A spring 307 is sleeved on the pull rod 303, and one end of the spring 307 is fixed to the fixed plate 305. The other end of the spring 307 is fixedly connected to the fixed cylinder 301. The fixed cylinder 301 is connected to the liquid storage tank 23 through the conduit 308. The fixed cylinder 301 is connected to the interior of the box body 21 through the connecting pipe 309. The atomizing nozzle 310 is fixedly installed at the end of the connecting pipe 309 away from the fixed cylinder 301. The atomizing nozzle 310 is inside the box body 21. One-way valves 311 are fixedly installed on the conduit 308 and the connecting pipe 309, respectively. The one-way valves 311 ensure that the liquid in the liquid storage tank 23 can only flow to the fixed cylinder 301 through the conduit 308, and the one-way valves 311 ensure that the liquid in the fixed cylinder 301 can only flow to the box body 21 through the connecting pipe 309.

[0024] Specifically, when the motor 24 drives the stirring blade 26 to agitate the housing 21 via the rotating shaft 25, the cam 27 rotates and contacts the fixed wheel 306 to compress the spring 307. The fixed wheel 306, via the fixed plate 305 and the pull rod 303, causes the piston 304 to slide in the fixed cylinder 301. When the cam 27 moves away, the spring 307 returns to its original position, and the piston 304 reciprocates to deliver the alkali solution to the atomizing nozzle 310. This design reduces reliance on the pump system, lowers costs, stabilizes the delivery speed, and improves the atomization effect. Furthermore, the motor 24 drives a single system, optimizing energy utilization. Example 2

[0025] Please see the appendix Figure 5 and attached Figure 6 The filter structure 4 includes a filter box 41, which is fixedly installed at the bottom of the box body 21. A slide rail 42 is fixedly installed on the inner wall of the filter box 41. The slide rail 42 slides the filter plate 44 through the slide bar 43. A sealing plate 45 is fixedly installed at one end of the filter plate 44. A handle 46 is fixedly installed on the side of the sealing plate 45 away from the filter plate 44.

[0026] Specifically, the filter plate 44 in the filter structure 4 can filter the gas and solids after the reaction. After long-term use, the filter plate 44 can be removed for cleaning or replacement to prevent solid particles from entering subsequent processes or being emitted into the environment, thereby improving the efficiency of the waste gas treatment system. When a large amount of impurities accumulates, it can be quickly replaced to ensure the continuous and efficient operation of the system. It also has low technical requirements for operators, enhancing the operability of the equipment.

[0027] Working principle of this utility model: This utility model is a waste gas rapid cooling and deacidification device. Waste gas is introduced into the liquid inlet pipe 29, and the motor 24 is started. The motor shaft of the motor 24 drives the rotating shaft 25 to rotate, which in turn drives the stirring blade 26 and the cam 27 to rotate. When the cam 27 rotates and contacts the fixed wheel 306, it presses the fixed wheel 306, causing the fixed wheel 306 to move towards the fixed cylinder 301. At this time, the fixed wheel 306 drives the piston 304 to slide in the fixed cylinder 301 through the fixed plate 305 and the pull rod 303. At the same time, the fixed plate 305 compresses the spring 307, and the piston 304 compresses the liquid in the fixed cylinder 301. Because the guide pipe 308 and the connecting pipe 309 are equipped with a one-way valve 311, the fixed plate 305 compresses the spring 307, and the piston 304 compresses the liquid in the fixed cylinder 301. The liquid in the fixed cylinder 301 flows to the atomizing nozzle 310 through the connecting pipe 309. The liquid is atomized by the atomizing nozzle 310 and then sprayed out. The agitator 26 stirs the exhaust gas and atomized liquid in the box 21, making them evenly mixed and fully reacted. When the cam 27 moves away from the fixed wheel 306, the fixed wheel 306 and the fixed plate 305 automatically reset under the elastic force of the spring 307, thereby driving the pull rod 303 to move. The pull rod 303 drives the piston 304 to move back. At this time, the internal air pressure of the fixed cylinder 301 decreases, allowing the liquid in the liquid storage tank 23 to flow into the fixed cylinder 301 through the conduit 308, thereby replenishing the fixed cylinder 301 with alkali solution. There is no need to install a water pump to spray alkali solution into the box 21.

[0028] After the alkaline solution and exhaust gas in the chamber 21 have finished reacting, the control valve 28 is opened, allowing the reacted gas, solid impurities, and alkaline solution in the chamber 21 to flow downwards through the control valve 28 into the filter chamber 41. The alkaline solution is then filtered by the filter plate 44. An external receiving box is placed at the bottom of the filter chamber 41 to collect the reacted alkaline solution. After the filter plate 44 has been filtering for a long time, the handle 46 is pulled. The handle 46, through the sealing plate 45, causes the filter plate 44 and the slide bar 43 to slide in the slide rail 42, thereby removing the filter plate 44 for easy cleaning or replacement.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
