Description

Technical Field

[0001] This utility model relates to the technical field of conveying equipment for dry sodium bicarbonate desulfurization, specifically a conveying equipment for dry sodium bicarbonate desulfurization. Background Technology

[0002] The baking soda dry desulfurization process is a highly efficient desulfurization technology. It uses a fan to spray pulverized baking soda solid ultrafine powder directly into the reaction tower through multiple nozzles. Baking soda can effectively remove acidic pollutants in flue gas through chemical adsorption. At the same time, baking soda also has physical adsorption capabilities, which can remove some inorganic and organic trace substances, thereby removing a large number of harmful substances in the flue gas.

[0003] Currently, in existing technologies, a blower is typically used to transport pulverized baking soda from the silo to the furnace or reaction tower via a conveying pipeline. However, this structure still has shortcomings. For example, baking soda powder has a certain degree of hygroscopicity, which makes it very easy for the powder to clump together in the silo. Clumped baking soda can easily clog the silo, resulting in reduced or even interrupted conveying efficiency. Therefore, it is necessary to propose a conveying device for dry baking soda desulfurization. Utility Model Content

[0004] To address the shortcomings of existing technologies, such as the problem that baking soda easily absorbs moisture and causes clumping, leading to conveying blockages, this invention proposes a conveying device for dry baking soda desulfurization.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a conveying device for dry sodium bicarbonate desulfurization, including a fixed frame, a conveying fan is provided on one side of the top of the fixed frame, a filter mechanism is provided on the top of the conveying fan, and a feeding mechanism is provided on the top of the filter mechanism.

[0006] The filtration mechanism includes a grinding chamber and a filtering chamber. The grinding chamber is located on top of the conveying fan, and the filtering chamber is located on top of the grinding chamber. Both the grinding chamber and the filtering chamber are located on one side of a fixed frame. The grinding chamber has a first filter plate inside, and a grinding shaft is located on top of the first filter plate. A first motor is located on top of the grinding chamber, and the first motor drives the grinding shaft to rotate. The filtering chamber has a second filter plate inside, and the second filter plate is inclined. A feeding pipe is located on one side of the bottom of the filtering chamber, and a discharge pipe is located on the other side of the bottom of the filtering chamber.

[0007] Preferably, a discharge valve is provided at the bottom of the grinding chamber, and one end of the discharge valve is fixedly connected to the end of the conveying fan.

[0008] Preferably, a first material distribution chamber is provided on one side of the inner cavity of the filter chamber, and the feeding pipe is fixedly connected to the bottom of the first material distribution chamber and extends into the inner cavity of the grinding chamber.

[0009] Preferably, a second material distribution chamber is provided on the other side of the filter chamber, and the discharge pipe is fixedly connected to the bottom of the second material distribution chamber.

[0010] Preferably, the feeding mechanism includes a conveying pipe, which is fixedly connected to the top of the filter chamber, and a spiral conveying shaft is provided inside the conveying pipe.

[0011] Preferably, one end of the spiral conveying shaft extends out of the conveying pipe and is fixedly connected to a second motor, which is fixedly connected to the top of the fixed frame.

[0012] Preferably, a feed hopper is fixedly connected to the top of the conveying pipe, and the feed hopper is in communication with the conveying pipe.

[0013] The advantages of this utility model are:

[0014] This invention introduces baking soda into a feeding mechanism, which pushes the baking soda into a filter chamber. Larger clumps of baking soda are guided by a second filter plate to the discharge pipe, while smaller granules and powdered baking soda fall into a grinding chamber through the second filter plate and the feeding pipe. The smaller granules remain on the first filter plate, and a first motor drives a grinding shaft to grind the smaller granules. The ground baking soda and powdered baking soda are then conveyed by a conveying fan to the reactor tower for desulfurization reaction, thus achieving the effect of filtering out clumps of baking soda and preventing conveying blockages. This solves the problem that baking soda easily absorbs moisture, causing clumps and leading to conveying blockages. Attached Figure Description

[0023] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0024] This application discloses a conveying device for dry sodium bicarbonate desulfurization. (Refer to...) Figures 1-5 A conveying device for dry sodium bicarbonate desulfurization includes a fixed frame 1, a conveying fan 2 on one side of the top of the fixed frame 1, a filter mechanism 3 on the top of the conveying fan 2, and a feeding mechanism 4 on the top of the filter mechanism 3. By introducing sodium bicarbonate into the feeding mechanism 4, the feeding mechanism 4 pushes the sodium bicarbonate into the filter mechanism 3. The filter mechanism 3 guides the clumps of sodium bicarbonate out and grinds the smaller particles of sodium bicarbonate. The ground sodium bicarbonate powder is guided by the conveying fan 2 into the reaction tower for desulfurization reaction, thereby achieving the purpose of filtering sodium bicarbonate clumps and preventing blockage of the conveying device.

[0025] The filtration mechanism 3 includes a grinding chamber 31 and a filter chamber 32. The grinding chamber 31 is located on top of the conveying fan 2, and the filter chamber 32 is located on top of the grinding chamber 31. Both the grinding chamber 31 and the filter chamber 32 are located on one side of the fixed frame 1. A first filter plate 33 is provided inside the grinding chamber 31, and a grinding shaft 35 is provided on top of the first filter plate 33. A first motor 34 is provided on top of the grinding chamber 31, and the first motor 34 drives the grinding shaft 35 to rotate.

Smaller granular and powdery baking soda is introduced into the grinding chamber 31 through the feeding pipe 311 via the second filter plate 39. The first motor 34 at the top of the grinding chamber 31 drives the grinding shaft 35 to grind the smaller granular particles along the first filter plate 33. The ground powdery baking soda is guided into the reactor by the conveying fan 2 through the grinding chamber 31 for desulfurization reaction.

The second motor 44 is fixedly connected to the top of the fixing frame 1. A feeding hopper 41 is fixedly connected to the top of the conveying pipe 42. The feeding hopper 41 is connected to the conveying pipe 42. By introducing baking soda into the feeding hopper 41, the baking soda enters the conveying pipe 42 through the feeding hopper 41. The second motor 44 drives the spiral conveying shaft 43 to rotate, and the spiral conveying shaft 43 pushes the baking soda in the conveying pipe 42 into the filter chamber 32, thereby achieving the purpose of controlling the amount of baking soda fed.

[0028] Working principle: During use, the feeding mechanism 4 introduces baking soda, which, together with the filtering mechanism 3, filters out clumps of baking soda. The baking soda is introduced into the feeding hopper 41 and then enters the conveying pipe 42. The second motor 44 drives the screw conveyor shaft 43 to push the baking soda in the conveying pipe 42 into the filter chamber 32. The clumps of baking soda fall onto the second filter plate 39, which guides them to the second distribution chamber 38 and then out through the discharge pipe 3. 10. Smaller granular and powdered baking soda falls through the second filter plate 39 into the first distribution bin 37 and is introduced into the grinding bin 31 by the feeding pipe 311. The smaller granular baking soda falls onto the first filter plate 33. The first motor 34 drives the grinding shaft 35 to grind the smaller granular baking soda along the first filter plate 33.
