In the field of environmental protection, Henan Yongle Group is playing an important role as a professional third-party solution provider for organic solid waste treatment in China. The group integrates environmental remediation engineering technology development, equipment manufacturing, environmental engineering investment, construction, operation and environmental engineering technology consultation, etc., and is committed to building a comprehensive environmental protection engineering technology system.

In terms of fly ash hazardous waste treatment, the fly ash hazardous waste treatment equipment of Henan Yongle Group shows unique treatment process and characteristics. Fly ash from silo storage and in the form of jumbo bags in the warehouse, together with contaminated salts, is first pre-dissolved and then pumped to the fly ash wash section. In this link, the fly ash undergoes water washing and pressure filtration process, and the low chlorine ash after treatment enters the thermal desorption system. The product ash successfully removed from dioxin by thermal desorption will be sent to the product warehouse for storage. These product ash will be used as the raw material for the geopolymer cementing material project to realize resource reuse.

However, the leached solution after washing with waste salt and fly ash water will be pretreated first and then sent to the preheater. Here, the leach liquor exchanges heat with the condensate produced by evaporative crystallization, and the feed liquor is heated up by ingeniously preheating the condensate produced by the system, and then sent to the sodium chloride evaporative crystallizer for evaporative operation. With the evaporation process, the sodium chloride crystallizes and separates out, the salt slurry is discharged from the salt foot of the evaporator, and then transferred to the centrifuge by the discharge pump for separation, so as to obtain the sodium chloride wet salt. The wet salt is dried and packaged, and finally becomes the by-product sodium chloride.

The mother salt solution is discharged from the evaporative crystallization and sent to the third stage flash crystallizer in turn. During flashing, the solution cools and the potassium chloride crystallizes out. The potassium chloride slurry is transferred to the centrifuge by the discharge pump to obtain potassium chloride. After the wet salt is packaged, another by-product potassium chloride is produced. It should be noted that the KCl mother liquor is partially returned to the salt evaporative crystallizer for recycle operation to improve the recovery rate of potassium sodium salt; The other part of mother liquor enters mother liquor drying unit for treatment, and finally gets carnallitite.

With a set of scientific and systematic treatment process, the fly ash hazardous waste treatment equipment of Henan Yongle Group shows strong strength in the field of organic waste treatment. It is widely used, not only assisting various industrial enterprises to properly handle fly ash hazardous wastes and reduce environmental risks, but also creating additional economic values for enterprises through resource utilization and promoting the sustainable development of environmental protection industry.

Yongle Environmental Protection is mainly engaged in the research and development, production and sales of complete sets of technical equipment for organic solid waste disposal and comprehensive utilization. Production and manufacturing, domestic waste treatment equipment, tire pyrolysis equipment, medical waste disposal equipment, hazardous waste disposal equipment, and achieve efficient and comprehensive utilization of resources through independently developed low-temperature anaerobic pyrolysis equipment technology solutions.
