Description

Technical Field

[0001] This invention relates to the field of solid waste treatment technology, and in particular to a solid waste treatment device for absorbing carbon dioxide. Background Technology

[0002] Solid waste resource utilization and carbon dioxide emission reduction have become key issues. Large quantities of solid waste, such as steel slag and waste concrete powder, are produced in enormous quantities. Direct disposal not only occupies land resources but also risks environmental pollution. Utilizing carbonation reactions to treat such solid waste can convert free calcium oxide and magnesium oxide into carbonates, solving the volume stability problem caused by their incorporation into concrete, while also achieving carbon dioxide fixation and emission reduction, thus possessing both environmental and economic value. However, current reaction efficiency between solid waste and carbon dioxide is generally low, and existing treatment equipment is insufficient to meet the demands of large-scale industrial processing, urgently requiring technological breakthroughs.

[0003] The current solid waste carbonization treatment faces many challenges. Insufficient contact area between solid waste particles and carbon dioxide, and poor mass transfer efficiency, result in slow reaction rates. Physical treatment equipment, such as simple stirring reactors, lacks in-depth optimization of the solid waste characteristics and gas-solid reaction process, making it difficult to effectively improve reaction efficiency and achieve large-scale and efficient solid waste carbonization treatment. Therefore, there is an urgent need to innovate physical treatment equipment to solve these problems. Summary of the Invention

[0015] Compared with the prior art, the present invention provides a solid waste treatment device for absorbing carbon dioxide, which has the following beneficial effects:

[0016] 1. This solid waste treatment equipment for absorbing carbon dioxide uses a drive motor to rotate a shaft and crushing blades to initially crush solid waste within a crushing chamber. During rotation, the first scraper continuously collides with protrusions, causing the crushing chamber to vibrate at high frequency. This causes the fine particles to pass through the screen holes and fall into a slurry tank, while the coarse particles that do not pass through remain in the crushing chamber for further crushing, ensuring thorough crushing without residue. Particles entering the slurry tank undergo secondary grinding by a grinding table and grinding wall. As the third scraper rotates with the shaft, it adheres closely to the inner wall of the slurry tank, scraping off the attached material and sending it into the grinding area. This multi-stage crushing, grinding, and vibrating screening design significantly reduces the particle size of solid waste, effectively increasing its contact area with carbon dioxide and laying the foundation for subsequent efficient carbonization reactions.

[0017] 2. This solid waste treatment equipment for absorbing carbon dioxide involves the following steps: Liquid in the collection tank flows in through the injection pipe and is then pumped evenly into the slurry tank via the spray pipe, forming a mixed slurry with the solid waste particles. The slurry is then discharged at high speed from the atomizing nozzle by a high-pressure pump through the discharge pipe, forming fine atomized particles. Simultaneously, carbon dioxide introduced through the inlet pipe enters the bottom tank through the inlet valve and is evenly sprayed out through the air guide holes, distribution pipes, and outlet pipes of the rotating shaft, thoroughly mixing with the atomized slurry. The heating element is controlled by an electronic control device to provide a suitable temperature for the carbonization reaction. A second scraper agitates the material at the bottom of the tank, ensuring uniform contact between the gas, liquid, and solid phases. This design allows for a full reaction between carbon dioxide and solid waste particles, significantly improving the carbon dioxide absorption efficiency and carbonization reaction rate.

[0018] 3. This solid waste treatment equipment for absorbing carbon dioxide utilizes a swing motor that drives a connecting plate via a rotating rod to swing the tank. As the movable block slides within the movable groove, a first spring and a first limiting telescopic rod provide cushioning and enhance the vibration effect. Simultaneously, a second spring and a second limiting telescopic rod between the connecting plate and the connecting frame further assist the vibration, ensuring uniform distribution of solid waste in the crushing and slurry tanks and preventing localized accumulation. An air suction hood and a vacuum pump guide gas from the tank into the intake pipe for recycling, reducing dust emissions and ensuring unreacted carbon dioxide participates in the reaction again. This swing vibration and air circulation design not only improves the uniformity of equipment processing but also enhances environmental performance, achieving efficient and low-carbon solid waste treatment.

The drive motor 21 drives the rotating shaft 35 and the crushing blade 25 to perform primary crushing of solid waste in the crushing box 34. During the rotation, the first scraper 26 continuously collides with the protrusion 33, causing the crushing box 34 to generate high-frequency vibration, which causes the fine particles after crushing to fall into the slurry tank 31 through the screen holes 46. The coarse particles that do not pass through remain in the crushing box 34 for further crushing, ensuring that the crushing is thorough and there is no residue. The particles entering the slurry tank 31 are subjected to secondary grinding by the grinding table 30 and the grinding wall 32. When the third scraper 36 rotates with the rotating shaft 35, it closely adheres to the inner wall of the slurry tank 31, scraping off the attached material and sending it into the grinding area. This multi-stage crushing, grinding and vibrating screening design can significantly reduce the particle size of solid waste, effectively increasing its contact area with carbon dioxide, laying the foundation for subsequent efficient carbonization reaction.

During the rotation, the first scraper 26 will contact and collide with the protrusion 33. During the rotation, the first scraper 26 will continuously collide with the protrusion 33, causing the crushing box 34 to generate high-frequency vibration, which will cause the fine particles after crushing to fall into the slurry tank 31 through the screen hole 46.

The third scraper 36 is fixedly connected to the rotating shaft 35 and is in natural contact with the inner wall of the slurry tank 31. After the liquid in the collection tank 4 flows in through the injection pipe 5, it is evenly sprayed into the slurry tank 31 by the water pump 43 through the spray pipe 42, forming a mixed slurry with the solid waste particles.
