New energy drying sludge filter press

New energy sludge drying equipment is a blessing Airlines company developed treatment sludge drying apparatus, the apparatus mainly solar and thermal energy as the main source of water in the sludge drying process; the use of independent research and development Long rack paver sludge cloth, turned mixed, receipts; the use of advanced automatic control technology acquisition and adjustment theory and numerical integration; and advanced laboratory equipment and instruments to monitor the results of monitoring compared to determine Science sludge pumping, automatic cloth, automatic turned mixed, automatic rewinding and other processes, and ultimately achieve the best ratio of solar and geothermal energy utilization, efficient and stable sludge drying process. 1. "urban sewage treatment plant sludge treatment and disposal of sewage and pollution control technology policy" (built the city [2009] No.23), requested "urban sewage treatment plants," new construction, renovation and expansion, the sludge treatment and disposal facilities and sewage treatment should At the same time planning facilities, constructed and put into operation. "2," on the strengthening of municipal wastewater treatment plant sludge pollution prevention and control work, "(Central Office [2010] No. 157), requested" the sewage treatment plant to storage (ie, not disposal) for the purpose of the factory sludge transport sector It must be dewatered sludge to a water content of about 50%. "3," China's 12th Five-Year Plan "Box 11" environment treatment project clearly states that "accelerate the construction of urban sewage, sludge, waste disposal facilities." 4, "" second five "national urban sewage treatment and recycling facilities construction plan "clearly the" sludge disposal costs will be gradually incorporated into the cost of sewage treatment and included contributions scope to strengthen the collection and management of user-owned water sewage treatment fee, provide funds to ensure that sewage treatment facilities. "5 "The State Council on accelerating the development of energy-saving environmental protection industry opinions" (Guo Fa [2013] No. 30) clearly states that "focus on the development of sludge minimization, sound, resource-based technology and equipment." 1, and Europe contrast with the process technology name Solia Helantis Huber SRT Fu Hang (FUHANG) developer Veolia Degremont Huber SRT Fu Hang green greenhouse Closed / Open Closed Open Active Solar Greenhouse (patent) sludge sludge pile stacked manner, the width and height is determined by the turning means sludge bed sludge thickness of 40cm sludge bed sludge bed thickness of 40cm, 20cm thickness turn mud system Solim ax or integrated agricultural tractors turn mud rotary drum rotary drum leaping turn mud machine (patent) ventilation system fan discharge machine and layered and layered natural ventilation exhaust fan ventilation fan base and fresh air ventilation combined transport sludge into a spiral decoration, lose the pump, moving mud fight mud fight spiral movement transmission means lose mud pumps, mobile sludge pump mud fight, moving mud fight odor treatment according to the actual location of choice in most cases odorless situation to handle mixed heterotrophic and autotrophs deodorant deodorizing device to determine the type of program that all mechanical sludge dewatering sludge according to the actual situation After all mechanical and digested sludge dewatering sludge and digested sludge dewatering sludge all machinery and all mechanical dewatering sludge digestion and sludge digestion sludge solid content of 45% -90% 45% -80% 75% 50% 85% process has the advantage of high flexibility; continuous operation; active sludge treated sludge to follow moving from the inlet to the outlet, while the flip, continuous operation. There is no limit greenhouse size when design; a high degree of automation. Heat pump as an auxiliary heat source, capable of continuous production; fully automated control system (patented), the middle part without personnel. . 2, new energy and other energy analysis and comparison of energy consumption required number of types of energy, the fuel cost price (yuan) required fee ($) new energy and energy saving compared to other a new energy [solar energy and air accounted for 75%, the heat pump 25%] 429828kcal ÷ 7055kcal / kwh = 60.9kwh 0.8 元 / kwh 48.72 ☆ ☆ ☆ ☆ ☆ 2 new energy coal 429828kcal ÷ 2752kcal / kg = 156.2kg 0.9 元 / kg 140.58 3 65.34% energy saving than coal gas 429828kcal ÷ 6450kcal / m3 = 66.64m3 3 元 / m3 199.92 gas saving ratio 75.63% 4 electric 429828kcal ÷ 817kcal / kwh = 526.1 kwh 0.8 元 / kwh 420.88 88.44% than the electrical energy-5 diesel boiler 429828kcal ÷ 8670kcal / kg = 49.6kg 9.37 元 / kg 464.75 89.52% than oil saving of 1 ton of sludge treated water 80% to 30% moisture content, takes heat 429828kcal example, by calculating the above conclusions. 3, different economic processes and pollution treatment processes tons of mud contrast No. investment (million) operating costs (yuan / ton) resource utilization options for environmental advantages and disadvantages of the new energy, new building materials sludge treatment 15-2560-130 , fuel or fertilizer cost Low-energy light a larger area 25-30120-150 2 aerobic fermentation composting to produce organic fertilizer-can achieve agricultural secondary pollution of heavy metals on soil brought 3 aluminum gel cured (lime) 10-12180-200 not use heavy investment less serious secondary pollution 4 thermal drying 40-50330-400 building materials or fuel micro traditional technology mature technology requires high cost plus 5 drying fuel burning 40-70330-470 Microprocessor complete high costs, not utilized effectively
