Description
Technical field: the present invention relates to a kind of sludge synthetic fuel, particularly a kind of mud (80% is moisture) that can produce the municipal sewage plant is through deep dehydration, mummification, innoxious, batch mixing is synthetic with the standard coal combustionproperty is suitable with calorific value and the environmental protection value is more excellent fuel.
Background technology: prior art is moisture 80% deeply dehydrating sludge, and the heat energy that the mud of mummification to moisture 40% consumes is big, cost is high, and the raw coal ratio height that adds in the compound, and complex process is unfavorable for energy-conservation and saves cost.
Summary of the invention: the present invention adds auxiliary material earlier with moisture 80% mud, make it harmless and be beneficial to the mechanical type deep dehydration to moisture below 50%, and then oven dry is to moisture 20%, mix with auxiliary materials such as sewer oil, raw coal and sanitass again and generate the particulate state sludge synthetic fuel, be conducive to energy-conservation and the saving cost, and the production scene cleaning, no waste gas and wastes pollutes.
The solution that realizes the object of the invention is: sludge fuel synthetic, comprise a mud (moisture 80%) storage bin, transfer roller, a kind of No. 1 auxiliary material and an adding material device, stirrer, steel band type pressure filter, knife mill, mud air flow dryer, a kind of No. 2 auxiliary materials and an adding material device, mixer, rotary conveyor, hot-air stove, electric automatic measurement and control cabinet and several groups connect closed guard, air suction inlet, vent-pipe, and heat-insulating material form.Described transfer roller is delivered to the mud in the storage bin (moisture 80%) in the stirrer, stirs according to a certain percentage with No. 1 auxiliary material of being sent here by described adding material device, sends in the steel band type pressure filter strong force squeezing dehydration automatically to moisture mud cake below 50%; Through described knife mill mud cake is shredded, and send in the mud air flow dryer oven dry to 20%; Automatically enter in the described mixer, evenly mix by a certain percentage with No. 2 auxiliary materials of being sent here by described adding material device, be sent to bedding plant by described rotary conveyor then and stack; Described mud air flow dryer venting port has heat exchange energy saver and water-bath device for eliminating smoke and dust, its air-blast system of described hot-air stove from described mud storage bin, stirrer, belt filter press etc. through the air suction inlet, the on-the-spot waste gas of vent-pipe suction operation, and make waste gas after described air flow dryer heat-exchanger rig one side draught heat, enter hot-air stove to burn and to remove the evil, and enter with the high-temperature hot-air that hot-air stove produces and to dry mud in the air flow dryer, hot-air stove is fuel used to be sludge synthetic fuel.The waste hot gas of the water content evaporation that described air flow dryer venting port is discharged enters water bath dust-removing device smoke prevention and dust control, innoxious release after heat-exchanger rig one is sidelong heat.Described air flow dryer and heat-exchanger rig thereof all adopt rock wool or polyurethane heat-insulation thermal insulation with hot-air stove and the mutual vent-pipe that is connected.Described mud air flow dryer hot air source is the boiler exhaust gas of available production site periphery also.Described equipment is put by described flow sequence, and mutual the linking installs, and joining place all adopts and connects the baffle plate sealing, and finishes automatic gauge and the control that batching, moisture content, temperature and system are moved by described electric automatic gauge housing.Described No. 1 auxiliary material is to be mixed by a certain percentage by lime, stalk bits or wood chip and sterilization and deodorization agent etc., in order to destroy mud cell tissue, is beneficial to dehydration, desulfurization and sterilization and deodorization; Described No. 2 auxiliary materials are mixed by a certain percentage by sewer oil, sanitas and standard raw coal etc. and form, and to improve the sludge fuel combustionproperty and to improve calorific value, make it suitable with the standard raw coal, and calorific value reaches 5000 kilocalories/more than the kg, environmental protection more, and energy long-term storage.Described transfer roller can be with spiral pump also available conveying belt.
The invention has the beneficial effects as follows:
1, digested the mud that urban life and trade effluent produce effectively, change harmful to treasure, having synthesized can be suitable with calorific value with the former coal combustibility of standard, more the fuel of environmental protection.
2, technology is reasonable, compact, perfect, and granular fuel is of many uses.
3, utilize lime, stalk bits or the auxiliary belt filter press of wood chip, realized to greatest extent the sludge deep mechanical dehydration to moisture below 50%, auxiliary with the hot blast mummification again, make moisture 80% deeply dehydrating sludge to moisture 20%, the heat energy that consumes only is 1/4 of single employing hot blast mummification power consumption, reduces the sludge synthetic fuel production cost more than 150 yuan/ton.
4, utilize the high heating value sewer oil to cooperate raw coal to improve sludge incineration performance and raising calorific value, salvage value is higher, the raw coal saving is more.
5, production scene mud and drying course exhaust gas discharged make the environment compliance with environmental protection requirements through collection, preheating, burning, heat exchange, smoke prevention and dust control, and cleaning is optimized, low-carbon emission.
6, Standardization instrument, production domesticization, level of automation height, investment is little, floor space is little,
Easy and simple to handle.
