Description

Technical Field

[0001] The utility model relates to the technical field of wastewater treatment, in particular to a high-salt wastewater evaporation and crystallization device. Background Art

[0002] Industrial wastewater includes production wastewater, production sewage and cooling water, which refers to wastewater and waste liquid generated in the industrial production process, which contains industrial production materials, intermediate products, by-products and pollutants generated in the production process that are lost with water. In various large-scale industrial productions, such as petroleum refining, coal chemical industry, electricity, fine chemicals, printing and dyeing, and pharmaceuticals, a large amount of salt-containing organic wastewater will be generated. Usually these wastewaters will be required to be reused, but after being reused, these wastewaters will produce a small amount of high-salt organic wastewater, which mainly contains various inorganic salts and organic matter and other pollutants. High-salt wastewater is a kind of wastewater with a high salt content. The salt inside it can be used in industry or other fields after extraction. Generally, the wastewater is filtered and then evaporated and crystallized to precipitate the salt from the liquid.

[0003] A high-salt wastewater evaporation and crystallization device is disclosed in the Chinese utility model patent application disclosure CN212609640U. Although the high-salt wastewater evaporation and crystallization device is provided with a stirring motor, a stirring shaft, a stirring frame and a stirring arm, the stirring frame is connected with a barrel wall scraper and a bottom wall scraper, which can not only stir the wastewater in the evaporation barrel to make it more evenly heated and improve the efficiency of evaporation and crystallization, but also prevent the crystals from adhering to the barrel wall and the barrel bottom, which is conducive to the discharge of the crystals. By providing a cover body, screws, cover holes and threaded holes, the cover body can be opened to facilitate the cleaning and maintenance of the device in the later stage. In order to improve the crystallization quality, when the wastewater enters the crystallization device, the impurities in the wastewater need to be filtered, but the existing crystallization device lacks a corresponding filtering device, has the disadvantage of poor crystallization quality, and the effect of cleaning the inner wall of the device is poor.

[0014] (III) Beneficial effects

[0015] The utility model provides a high-salt wastewater evaporation and crystallization device, which has the following beneficial effects:

[0016] 1. The high-salt wastewater evaporation and crystallization device has the effect of filtering and collecting impurities in the wastewater through the arrangement of the filter plate, the connecting rod, the dispersion plate and the collection box. When in use, the wastewater enters the crystallization barrel through the water inlet pipe, and is filtered under the action of the filter plate. The impurities in the wastewater remain on the upper surface of the filter plate. At this time, under the action of the servo motor, the rotating shaft is driven to rotate, and the rotating shaft drives the dispersion plate to rotate on the upper surface of the filter plate through the connecting rod. The impurities on the surface of the filter plate are dispersed outwardly through the dispersion plate, so that the impurities enter the collection box through the through groove, which plays the role of collecting impurities in the wastewater. By filtering the wastewater, the impurities in the crystal are reduced in the subsequent crystallization process, thereby achieving the purpose of improving the crystallization quality.

[0017] 2. The high-salt wastewater evaporation and crystallization device has the effect of preventing crystals from remaining on the inner wall of the crystallization barrel through the arrangement of the fixed block, the tightening block and the scraper. When in use, the crystallization barrel is heated by the heating device to gradually evaporate and crystallize the wastewater. During the crystallization process, the rotating shaft is driven to rotate by the servo motor, and the rotating shaft then drives the rotating rod, the stirring rod and the fixed block to rotate. The wastewater in the crystallization barrel is stirred by the rotating rod and the stirring rod to make the wastewater heated evenly. At the same time, due to the rotation of the fixed block, under the action of the spring, the scraper is always in contact with the inner wall of the crystallization barrel through the tightening block. At the same time, the continuously rotating scraper prevents the crystals from sticking to the inner wall of the crystallization barrel, thereby achieving the purpose of facilitating the cleaning of the inner wall of the crystallization barrel.
