            It is suitable for municipal sewage, petroleum refining, leather brewing, printing and dyeing, animal husbandry, coal processing, biochemical pharmaceuticals, steel pickling, chemical sugar making, food processing, etc.

            應用場合及優點


            High Efficiency Deep Sludge Dewaterer

            According to the sludge treatment technology proposed by western developed countries, combined with China's national conditions and energy saving and emission reduction policies, on the basis of extensive study and Research on domestic counterparts'sludge treatment technology, the company, with the help of scientific research institutions such as Shanghai Jiaotong University and Shanghai Tongji University, has explored a set of practical new sludge treatment technologies suitable for China's national conditions. The water content of sludge can be reduced to less than 60% by using a complete set of equipment and special conditioning agent for deep dewatering of sludge. The filtered sludge has high chemical stability and can be used for landfill covering and building materials. The existing problems of sludge treatment in China are effectively solved. At present, four types of specifications have been formed to meet different sludge treatment capacity and different needs of customers.

            The deep dewaterer of TMSD is divided into four pressure filters: low pressure, medium pressure, high pressure and ultra-high pressure. The pressure filters are automatically controlled by pneumatic components. The variable frequency speed regulation is adjusted according to the requirement of output and water content. The pressure filters change the traditional pattern of pressure filters after sewage coagulation, but paste sludge direct pressure filters.

            Application occasions and advantages

            It is suitable for municipal sludge, petroleum refining, brewing leather, printing and dyeing, paper making, coal chemical beneficiation, biochemical pharmaceuticals, steel pickling, chemical sugar making, food processing, etc. At the same time, the dewatering effect of fruit juice and residue of Chinese medicinal materials is more obvious. Advantages: The system has the advantages of simple operation, low operation cost, rapid dewatering of sludge directly by press filter after modification, no blockage, and the negativity of oily fibers.

             

            II. Low Temperature Drying of Sludge

            Sludge Low Temperature Drying Equipment

            The low-temperature drying equipment of sludge developed by Taimei Environment is based on the principle of low-temperature heat pump dehumidification, using convective hot air drying to dehydrate and dehydrate the wet sludge on the belt. The whole system is fully closed design, and there is no heat loss in hot air drying.

            Principle of Desiccant Heat Pump

            The refrigeration system is used to cool and dehumidify the wet air from the drying chamber while recovering the latent heat of water condensation and reheating the dry air. It is the combination of dehumidification (dehumidification and drying) and heat pump (energy recovery), and it is the recycling of energy in the drying process.

            Innovative technology

            Taimei Environment is a brand of four-effect condensation dehumidification and drying technology in China. It is also the most advanced technology of sludge drying and reduction. With the advantages of lower outlet temperature, better drying capacity and efficiency, and more economical operation cost, the comprehensive dehumidification performance ratio (SMER) of the four-effect condensation dehumidification and drying equipment is as high as 4.2 kg.H2O/kw.h, and the moisture content of dry mud is below 10%. It saves more than 50% energy than traditional low-temperature drying, which is twice the industry standard.

            Ⅲ. Low-temperature Concentration Technology of Dangerous Wastewater

             

            Sludge cryogenic concentrator

            Through the conversion of internal negative pressure system, distillation kettle, exchange system and heat energy system of equipment itself, the raw liquor of high-risk wastewater is heat exchanged, so that the raw liquor is gasified at 25-40 C, then recycled, and the remaining raw liquor is discharged from the outlet after reaching the set concentration value. The whole system is fully automated, easy to operate and stable to operate.

            Main Use of CDS Equipment

            At present, it mainly concentrates and decreases the hazardous waste liquids listed in the "HW8, 9, 12, 17, 31, 34" series by the state. The equipment is fully automated. The equipment is automatically adjusted to 25-40 degrees Celsius. The waste liquor boils and vaporizes automatically. After 20 minutes, the water in the waste liquor is distilled automatically. The concentrated waste liquor is discharged automatically after reaching the preset concentration value. The equipment automatically feeds, replenishes and discharges fluid.

            CDS設備用途


            Concentration rate of different high-risk wastewater (depending on the solid content of wastewater) is as high as 75%-90%.
