The waste hot air with moderate temperature and high humidity enters the heat recovery unit for the first condensation dehumidification, and then enters the evaporator in the refrigerant system for the second condensation dehumidification. Turn into medium temperature dry air, then to the condenser of the refrigerant system, the second temperature rise, up to 78 degrees, through the sludge surface, exothermic cooling, into medium temperature and high humidity air recycling. With the acceleration of social and economic development and urbanization, the amount of sewage sludge in urban areas is increasing.
VAPORUN has made a series of optimization and improvement of sludge drying system, thus becoming the most professional sludge drying equipment manufacturer in China. According to statistics, about 80% of the sewage plants have sludge concentration and dehydration facilities, which has reached a certain degree of sludge reduction. Most of the sludge in landfills, open-air stacking and transportation belongs to random disposal, and the proportion of real safe disposal is not more than 20%. Simple treatment of land encroachment is serious, and it is not easy to find a suitable site. At the same time, if the seepage prevention technology is not enough, it will lead to potential soil and groundwater pollution. For a long time, for the overall environment, it is equivalent to the lack of effective treatment of sewage.
The relative motion between the particles and the wedge surface produces a washing effect that washes away the adhering material on the surface of the blade, which allows the material to have a long residence time and a high fill factor. The cylinder is a jacket structure in which hot steam circulates inside. Because the agitating blade is shaped like a paddle, it is called a paddle dryer. The product can indirectly heat or cool the paste, granular, powder, and slurry materials, and can complete unit operations such as drying, cooling, heating, sterilization, reaction, and low-temperature combustion.
The CENTRIDRY® enhanced dewatering process offers a unique single stage process combining mechanical dewatering and thermal drying in a single compact machine with a small footprint. Situated in the Machinery Central, Zhengzhou Province, Henan Fote Heavy Machinery Co., Ltd. is one of the most professional sludge dryer manufacturers in China, and there are many types of sludge dryer for sale. Professional Fote engineers offer free consultation based on your requirements including sludge dryer price, solutions, flow chart, etc.
Some dryers produce dried sludge with a temperature low enough for it to be stored directly (e.g. Evaporis™ LE). However most thermal dryers require a dried sludge cooling system. The most commonly found system is the cooling screw conveyer system.
Please consult the supplier for specific discounts on each product. We install and adjust the equipment free of charge and standardize the training for users. Using data collected by textile machines sensors, ATHENA software system defines the parameters of the STANDARD PRODUCTION QUALITY. Discover all Athena’s advantages. In the same year, the company ufficially owns of the “SolWa” patent and is able to separate pollutants from pure water thanks to the only use of solar power.
If the compressed air supply is interrupted or the required minimum pressure is not present, the pressure sensor recognizes this and the SPS initiates the necessary measures. If this occurs during operation, the energy supply is immediately interrupted and the dryer is switched off. The sludge is very sticky and has a special sticky phase during the drying process (40%-60% moisture content). In this extremely narrow transition section, the sludge is easy to agglomerate, the surface is hard and difficult to crush, but the inside is still thin.
We will provide training with the equipment, maintenance, and troubleshooting procedures. Additional technical assistance will be available via telephone 24-hours per day. Today many of the municipalities and leading industries land apply there Biosolids. Due to rapid increase of population and development, it has become a challenge to find field sites to land apply.
Use Nissei or Nord brand reducers, industrial quality from Japan and Germany. Börger Rotary Lobe Pumps are self-priming , valveless, positive displacement pumps. Against new national call to develop sustainable economic mode, painting sludge gradually becomes a main problem paid attention by different customers.
The removal equipment can be a bulldozer, dragline, or front-end loader. Stabilized sludge is pumped into the lagoon over a period of several months until a lagoon depth of 0.6 to 1.2 m is achieved. Supernatant is decanted, either continuously or intermittently, from the lagoon surface and returned to the treatment plant. Depending on the climate and the depth of the sludge, the time required for dewatering to a final solids content of 20 to 40% may be 3 to 12 months.
