Description
Technical field
The present invention relates to a kind of waste treatment system, particularly relate to a kind of sludge drying and with the system of coal multifuel combustion.
Background technology
Along with the generation of municipal sewage and treating capacity increasing, the mud produced in the processing procedure of municipal sewage also grows with each passing day.The flock that mud is made up of moisture, organic granular and inorganic particle etc., wherein containing plurality of heavy metal, pathogen and difficult degradation toxic organic compound, also can emitting offensive odor.Therefore, must deal carefully with mud.
The pretreatment of mud has the technology such as conditioning, concentrated, dehydration, stabilisation and mummification, the final disposal of mud mainly contains the modes such as landfill, Land_use change, construction material utilization, biological treatment and burning, and the emerging technologies such as pyrolysis, gasification and pyrohydrolysis are also among research and development.Because all many-sided requirements such as soil protection, ground water protection and food security improve constantly, the application of the conventional art such as landfill and Land_use change faces increasing restraining factors, burns and develops rapidly with other sludge treatment new technology.
According to the fuel that CIU uses, sludge incineration can be divided into burns separately and burns two classes with other fuel mix; According to whether carrying out drying and other treatment, sludge incineration is divided into directly burns and burns two classes after mummification; According to adopted incinerator, sludge incineration can be divided into grate furnace burning, fluidized combustion, melting furnace burning, rotary kiln incineration and station boiler to mix burning etc.
Because the dewatered sludge from sewage treatment plant generally also has comparatively high-moisture percentage, calorific value is very low, and when directly entering stove burning, need more auxiliary fuel, the ratio of burning mixed mud is lower, and treatment scale is little, and the flue gas loss of boiler is large, and the thermal efficiency declines.Burning reentering stove after dewatered sludge mummification, stability and the treatment scale of stove combustion can be improved.
Mummification-incineration technology extensively adopts power plant's low-pressure steam and other heat medium dewatered sludge higher to the moisture content from sewage treatment plant to heat, make moisture in mud evaporate further and obtain the dewatered sludge that moisture content is lower, calorific value is higher, then send in boiler through dewatered sludge feeding system and burn; Burn the high-temperature flue gas produced to discharge after heat recovery and purified treatment, thus realize reducing sludge volume, decrement and innoxious.
Sludge heat drying link has direct mummification, indirectly drying and associating mummification three kinds of typical process.Direct mummification is in operation, and thermal medium (hot-air, heat smoke or heat ash etc.) directly contacts with mud, and thermal medium low speed flows through sludge blanket, absorbs the moisture in mud in the process, and the dewatered sludge after process need be separated with thermal medium.A waste gas part of discharging to get back in original system use again by heat recovery system, and remaining part is discharged after innoxious.In indirectly drying process, thermal medium does not directly contact with mud, but transfers heat to mud by heat exchanger, and the moisture in mud is evaporated, and thermal medium is generally 160-200 DEG C of saturated steam or conduction oil.Condensation in addition in the moisture evaporated in process to condenser, a part for thermal medium is got back in original system and is recycled, with economize energy.Directly-indirect associating mummification combines above-mentioned two kinds of technology.
In several conventional type of furnace of sludge incineration link, the process capacity of grate furnace, melting furnace and rotary kiln is all relatively little; The Fuel Consumption of large-scale fluidized bed boiler and pulverized-coal fired boiler is large, even if mix the mud of the lower ratio of burning, its mud handling capacity that can realize is still very large, and the mud mixing the lower ratio of burning can not have an impact to safe operation of the boiler, stove combustion is stablized, and temperature is high, pollutant complete decomposition, and these station boilers are often equipped with advanced flue gas purification system, the pollutant that it can bring sludge incineration carries out purified treatment.Visible, utilize station boiler to carry out cooperative disposal to mud and have a good application prospect.
In conjunction with different sludge dryings and burning mode, in the sludge drying of having gone into operation-burning engineering, just create steam mummification-fluidized combustion, steam mummification-pulverized-coal fired boiler mixes the different process route such as burning, flue gas mummification-rotary kiln incineration.Because most engineering undergoes technological transformation to the boiler controller system put into operation for many years, to increase sewage sludge storage, mummification and induction system, the needs of sludge incineration are not considered during initial design boiler controller system, so the sludge drying workshop set up generally adopts steam indirectly drying technique, distance between its position and boiler is usually far away, need the coal yard first dewatered sludge being transported to power plant to store up, then adopt Belt Conveying mode to send into pulverized coal preparation system, or directly send into burning in stove.This causes system flow complicated, and equipment is many, and floor space is large, and cost of investment is high; Again because the mud after mummification has airborne dust in stacking and course of conveying and foul smell distributes, and the sealing property of belt conveyor system is poor, so easily cause foul smell in plant area and near zone diffusion, cause work under bad environment, have a strong impact on the enthusiasm of power plant's burning sludge.At present, also the mud flue gas mummification-pulverized-coal fired boiler based on fanned powder-grinding system is had to mix firing technique scheme, but due to mud mummification the primary mixture produced in the process of grind into powder has stronger penetrating odor, corrosivity and very high dust concentration in fan mill, its gas powder is separated and acquires a certain degree of difficulty, requirement of explosion proof is also higher, there is not yet engineer applied.
Therefore for the needs of power plant's burning sludge, development system is succinct, flow process is short, the sludge anhydration burning electricity generation system of environment-friendly high-efficiency is necessary.
Summary of the invention
