What is the use of dried sludge?

图片
    Sludge refers to the water-containing solid sedimentation material produced during the sewage treatment process, including moisture, volatile substances and ash pathogens and toxic substances. However, due to the relatively high water content of sludge, it needs to be dried before it can be reused. The   sludge dryer   can achieve "reduction, stabilization and harmless" reuse of sludge.   The sludge dryer is suitable for drying various sludges, including electroplating sludge, printing and dyeing sludge, chemical sludge, biological sludge, municipal sludge, pharmaceutical sludge, etc. So, what is the use of sludge after drying?   1. Used for organic fertilizer, soil improvement, etc.   After the sludge is dried, its moisture and harmful substances will be removed, but the nutrients present in the sludge will not change in any way. Because the sludge contains higher contents of TN, TP, and TK, which are much higher than the ordinary fertilizers we u...

Advantages of mineral slag dryer

图片
    The   mineral slag dryer   is a dryer equipment mainly designed for slag and ore powder materials. The drying treatment of slag materials by its equipment is generally achieved by heat transfer. So what are the characteristics and advantages of the mineral slag dryer?   1. Stable operation. The slag dryer can dry a large amount of materials. The probability of failure during the drying process of materials is low and the operation is stable.   2. Energy saving and environmental protection. The entire production line of the slag dryer is tightly sealed, with less dust spillage, low energy consumption, less pollution to the environment, and energy saving.   3. Automated control. With the maturity of the slag dryer manufacturing technology, the equipment has been upgraded in all aspects. The entire production line of the equipment can be operated by 3 to 5 people, making the operation simple and convenient.   4. Multiple choices of heat sources. ...

What are the heat sources of sand dryers?

图片
    Common heat source equipment for   sand dryers   include pulverized coal burners, gas generators, biomass burners, wood powder burners, oil and gas burners, electric hot blast stoves, direct heating hot blast stoves, etc. The fuels used by different heat source equipment They are different, for example, a pulverized coal burner, a gas generator burns coal, a biomass burner burns some biomass pellets, a wood powder burner mainly burns wood powder pellets, etc., and an electric blast stove relies on electricity as a heat source. , the remaining hot blast stoves mainly burn biomass straw, wood and the like, while natural gas burners rely on natural gas as the heat source. The sand dryer production line uses different thermal fuels and has its own characteristics. For example, if coal is used as the heat source, the production cost is low, natural gas is cleaner, hot blast furnace investment is low, etc. Users can choose the appropriate fuel as the heat source o...

Is the cassava chip mesh belt dryer effective?

图片
    Jiutian   cassava chip mesh belt dryer   adopts a multi-layer structure, which can easily achieve two-, four- and six-layer drying. There are many options for heat sources for drying cassava chips, and the drying task can be easily completed with simple operations. In addition, the cassava chip mesh belt dryer is also equipped with an automatic control system that can monitor temperature and humidity in real time to ensure that the cassava chips are always in the best condition during the drying process.   Working principle: Materials are uniformly put on the mesh-belt by the feeder. The mesh-belt uses generally 12-60 mesh stainless steel wire net and it is drawn and moved inside the drier by a transmission device. The drier is composed of several units. For each unit, the hot air is circulated separately. Some exhausted gas is discharged with a special moisture elimination blower. The waste gas is controlled through an adjustment valve. The hot air pas...
