[0002] Ionic liquid desulfurization technology utilizes the special properties of ionic liquids, such as high solubility, reaction reversibility, and excellent designability, to achieve efficient absorption and resource utilization of sulfur dioxide. In ionic liquids, sulfur dioxide can react with cations or anions in ionic liquids to form soluble ionic compounds. This reaction is reversible and can be reversed under certain conditions to decompose the ionic compounds into ionic liquids and sulfur dioxide again.

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the specification of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Reference Figure 1 , Figure 2 and Figure 4 The utility model provides an embodiment: an ionic liquid desulfurization device with an anti-precipitation structure, comprising a tank body 1, characterized in that: a fixed platform 5 is fixedly connected to the bottom of the outer side of the tank body 1, and air pumps 6 are fixedly connected to the left and right sides of the top surface of the fixed platform 5, and the output ends of the two air pumps 6 are fixedly connected to air intake pipes 7, and the bottoms of the two air intake pipes 7 are both at the inner bottom of the tank body 1, and a discharge hopper 2 is fixedly connected to the bottom of the tank body 1, and a barrel body 3 is fixedly connected to the bottom of the discharge hopper 2, and a motor 4 is fixedly connected to the bottom of the barrel body 3, and a connecting rod 16 is fixedly connected to the output end of the motor 4, and a stirring paddle 15 is fixedly connected to the outer side of the connecting rod 16, and a stirring rod 18 is fixedly connected to the top of the connecting rod 16, and a cleaning device is provided at the inner top of the tank body 1.

[0031] By driving the air pump 6, gas can be blown from the air inlet pipe 7 to the inner bottom of the discharge hopper 2, so that the sediment can be stirred. Since the air inlet pipe 7 is located at the inner bottom of the feed hopper, the reaction distance between the required desulfurization gas and the desulfurizer is lengthened, thereby improving the desulfurization efficiency. At the same time, the driving motor 4 can drive the connecting rod 16 to rotate, and the connecting rod 16 can drive the stirring paddle 15 and the stirring rod 18 to rotate, so as to stir the sediment inside the barrel body 3. Through the cooperation of the air pump 6 and the motor 4, the accumulation of sediment can be further avoided.

[0032] Reference Figure 1 , Figure 2 and Figure 3 One side of the stirring rod 18 is in contact with the inner wall of the discharge hopper 2, the tank body 1, the discharge hopper 2 and the barrel body 3 are interconnected, a discharge pipe 13 is fixedly connected to one side of the bottom of the barrel body 3, a valve 14 is arranged on the outside of the discharge pipe 13, the cleaning device comprises a base 20 and a nozzle 21, a water pump 8 is fixedly connected to the top of the tank body 1, a water inlet pipe 9 is fixedly connected to the output end of the water pump 8, a plurality of nozzles 21 are arranged on the bottom of the base 20, a filter screen 19 is fixedly connected to the inner top of the tank body 1, the water inlet pipe 9 is fixedly connected to the base 20, the base 20 is located at the inner top of the tank body 1, the interior of the base 20 is arranged as a hollow structure, and the water inlet pipe 9, the nozzle 21 and the base 20 are interconnected, and a one-way valve 22 is arranged inside the two air inlet pipes 7.

[0033] By fitting one side of the stirring rod 18 with the inner wall of the discharge hopper 2, the sediment on the inner wall of the discharge hopper 2 can be scraped off. After the reaction is completed, the one-way valve 22 provided inside the intake pipe 7 can be used to prevent the desulfurizing agent from entering the intake pipe 7.

[0034] Reference Figure 1 , Figure 2 and Figure 3 The top of one side of the tank body 1 is fixedly connected with an air outlet pipe 12, which is located between the filter screen 19 and the base 20. The top of the other side of the tank body 1 is fixedly connected with a feed pipe 10, and a feed port 17 is provided on the top of the other side of the tank body 1. The top of the feed pipe 10 is threadedly connected with a sealing cover 11. The feed pipe 10, the feed port 17 and the tank body 1 are interconnected. The bottom of the fixed platform 5 is fixedly connected with a support leg.

[0035] By opening the sealing cover 11, the desulfurizer can enter the tank body 1. During the reaction, the sealing cover 11 is closed, and the impurities inside the gas can be filtered using the filter 19. The filtered gas is discharged through the outlet pipe 12. When the desulfurization of the desulfurizer is completed, the valve 14 is opened to discharge the waste inside the barrel body 3 through the discharge pipe 13.

[0036] Working principle: when in use, first open the sealing cover 11 to allow the desulfurizer to enter the tank body 1, and then connect the air pump 6 to allow the desulfurized gas to enter the inner bottom of the feed hopper through the air inlet pipe 7. At this time, driving the air pump 6 can allow the gas to stir the sediment in the feed hopper. Since the air inlet pipe 7 is at the inner bottom of the tank body 1, the contact time between the desulfurizer and the gas is prolonged. The driving motor 4 can drive the stirring paddle 15 to rotate, thereby stirring the sediment accumulated at the bottom of the barrel body 3 to prevent the pipeline from being blocked due to the accumulation of sediment. When the stirring rod 18 rotates, one side of the stirring rod 18 contacts the inner wall of the discharge hopper 2, so that the sediment attached to the inner wall of the discharge hopper 2 can be scraped off, thereby In order to prevent the accumulation of sediment in the first step, the gas generated during the reaction will float upward. The one-way valve 22 arranged inside the air inlet pipe 7 can prevent the desulfurizer from entering the air inlet pipe 7. At this time, the filter 19 can filter the impurities inside the gas, and the filtered gas is discharged through the air outlet pipe 12. When the desulfurization of the desulfurizer is completed, the valve 14 is opened to discharge the waste inside the barrel 3 through the discharge pipe 13, and then the water pump 8 is driven to allow water to enter the base 20 through the water inlet pipe 9. Through the multiple nozzles 21, the water can be divided into multiple streams for spraying, so that the filter 19 and the entire device can be cleaned, and the sewage after cleaning is discharged through the discharge pipe 13, thereby improving the convenience of the device.
