Description

Technical Field

[0001] The invention relates to the technical field of fly ash water washing liquid, and more specifically to an integrated equipment system for high-temperature sodium and low-temperature potassium precipitation of fly ash water washing liquid. Background Art

[0002] With the enhancement of environmental awareness and the improvement of energy efficiency, the resource utilization of industrial waste has received more and more attention. Fly ash, as a kind of industrial waste, contains a certain amount of recyclable metal elements, such as sodium (Na) and potassium (K). However, traditional fly ash treatment devices have many limitations in extracting these metal elements, especially in the process of sodium and potassium precipitation.

[0003] At present, most fly ash water washing liquid treatment devices on the market adopt a single-function design in the sodium and potassium separation processes, that is, separate sodium separation equipment and potassium separation equipment are designed separately. This design not only increases the equipment footprint and cost investment, but also in actual operation, due to the complex and changeable composition of fly ash water washing liquid, a single device is difficult to adapt to various working conditions, resulting in a high equipment blockage rate and greatly increased maintenance costs.

[0004] Specifically, traditional sodium precipitation equipment operates under high temperature conditions, while potassium precipitation equipment needs to operate under low temperature conditions. Due to the lack of effective connection and coordination between equipment, the fly ash water wash liquid is prone to precipitation and crystallization during the transfer process, causing pipeline blockage. In addition, due to differences in operating temperature, pressure, flow rate and other parameters of different equipment, it also increases the difficulty of matching between equipment and reduces the operating efficiency of the entire system. In view of this, we propose an integrated equipment system for high-temperature sodium precipitation and low-temperature potassium precipitation of fly ash water wash liquid.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The present invention improves the existing sodium and potassium separation equipment of fly ash water washing liquid, arranges a reaction regulating tank on the mounting base, adjusts key parameters such as the pH value of the water washing liquid, and then heats or cools the water washing liquid through a temperature exchange mechanism, and injects cold water or hot water into the temperature pipe to achieve the effect of cooling or heating the water washing liquid.

The present invention realizes the continuous operation of high-temperature sodium separation and low-temperature potassium separation by optimizing the process flow, reduces equipment investment and operating costs, and is conducive to improving the application prospect and market competitiveness of resource utilization of fly ash water washing liquid.

[0017] 2. The present invention arranges a tank body between the input tank and the output tank, an exchange chamber is arranged inside the tank body, a plurality of connecting holes are opened at both ends of the tank body, and connecting pipes are connected between the connecting holes. The fly ash washing liquid is input into the connecting holes through the input tank and output to the output tank through the connecting pipe. During the transportation by the connecting pipe, cold water or hot water is injected into the temperature pipe to enter the exchange chamber, and the fly ash washing liquid in the connecting pipe is cooled or heated, thereby optimizing the heating crystallization and cooling crystallization processes, improving the energy utilization efficiency, reducing the energy consumption, efficiently producing high-quality sodium chloride and potassium chloride, and facilitating a new process of sodium and potassium precipitation of fly ash washing liquid.

[0018] 3. The present invention sets a bearing shell between the output tank and the exchange tank, drives the servo motor to drive the worm to rotate, the worm meshes with the worm wheel to rotate, the worm wheel drives the rotating tube to rotate at the output end of the output tank, the rotating tube drives the rotating shaft to rotate, the rotating shaft drives the rotating arm to rotate, the rotating arm drives the inclined surface B to contact the inclined surface A of the limit block, squeezes the limit block, and makes the limit block separate from the limit groove. Under the action of the tension spring, the scraping ring explodes and rotates to scrape away the sodium and potassium crystals precipitated at the output end of the tank body to prevent crystal condensation and blockage. Compared with the ordinary scraping mechanism, the anti-blocking mechanism of the present invention has the effect of powerfully scraping away crystals to prevent condensation and blockage, which significantly reduces the risk of blockage of the equipment during the sodium and potassium precipitation process.

[0019] 4. The present invention arranges a reduction motor at the top of the precipitation tank, drives the reduction motor to rotate the driving rod, drives the rotating shell to rotate, drives the tumbling rod, the limiting rod and the tumbling plate rotatably connected on the outer wall of the rotating shell to rotate, and the limiting rod rotates into the rotating slide formed by the positioning groove and the connecting arm of the fixed shell. Due to the limitation of the positioning groove and the limiting rod, the tumbling rod and the tumbling plate rotate, and when the solid-liquid separation precipitation operation is performed inside the precipitation tank, the crystals are tumbled up and down in a small range in the vertical direction at the bottom of the precipitation tank, so as to prevent the sodium and potassium crystals from sticking to each other and agglomerating, and further improve the performance. The vortex formed by the stirring rotation makes the precipitation tank form a vortex, which makes it impossible for the sodium and potassium crystals to precipitate, which greatly affects the separation effect. In addition, the stirring method has a poor effect on the adhesion treatment of the crystals, and cannot ensure the continuity and efficiency of the sodium and potassium precipitation processes. The tumbling plate of the present invention makes the crystals intermittently tumble up and down at the bottom of the precipitation tank, which not only prevents agglomeration and condensation, but also has an anti-blocking effect, and does not affect the separation efficiency, which is helpful to improve production efficiency and further optimize and reduce production interruptions and losses caused by equipment blockage.
