Background technology
Municipal sludge is that Sewage Plant processes solid sediment produced by waste water, and along with improving constantly of the growing of population and urbanization degree, the treating capacity of municipal sewage increases sharply, and the now built sewage treatment plant run of China is more than 3340。Typically containing the harmful components such as organic pollution, heavy metal, parasite, pathogen in municipal sludge, untreated urban environmental hygiene is caused has a strong impact on；How properly and scientifically lignin-sludge, and make full use of the resource in mud, make up to minimizing, stabilisation, innoxious and resource have important practical significance。
Sludge incineration processes and is possible not only to realize the minimizing of mud to greatest extent and innoxious, and incineration slag can also make auxiliary product, is a kind of effective sludge treating method。It is fast that sludge incineration has processing speed, and treating capacity is big, and floor space is little, it is not necessary to long term storage, can on-site incineration, it is not necessary to long-distance transportation, it is possible to recover energy for the feature such as heat supply or generating。Sludge incineration is capable of the maximum minimizing of mud, and along with its application is more and more extensive, sludge incineration is considered as one of method the most promising in Sludge Disposal Techniques。
Summary of the invention
The present invention seeks to: provide one to alleviate municipal sludge incinerator load, it is achieved municipal sludge is controlled oneself to balance and burned, and improves municipal sludge incinerating method and the CIU of firing efficiency。
The technical scheme is that a kind of municipal sludge incinerating method, specifically include following steps:
1) from mudpan, take out mud, adopt pressure filter one to carry out first time filter pressing, then adopt pressure filter two to carry out second time filter pressing, obtain the semi-dry sludge that moisture content is 50%-60%；
2) semi-dry sludge step 1) obtained puts into vertical sludge and dries incinerator, and provides the combustion air needed for sludge incineration in stove by high pressure blower, then carries out controlling oneself balancing and burns；
3) by step 2) in vertical sludge dry incinerator discharge tail gas carry out after primary dust removing through cyclone dust collector, enter air-introduced machine, then pass sequentially through dust collect unit by water, carbon adsorption device purify, finally by smoke stack emission to air。
As preferred technical scheme, step 2) in vertical sludge dry incinerator burn after produce slag be used for preparing brick, haydite or air entrained concrete construction material。
A kind of municipal sludge CIU, including:
Mudpan, is used for collecting, precipitating municipal sludge；
Pressure filter one, for carrying out first time filter pressing by the mud taken out from mudpan；
Pressure filter two, is connected with described pressure filter one, for the mud after first time filter pressing carries out second time filter pressing；
Vertical sludge dries incinerator, is connected with described pressure filter two, and the semi-dry sludge through twice filter pressing carries out balance burning of controlling oneself；
And high pressure blower, dry with described vertical sludge and connect bottom incinerator and to air blast in stove, it is provided that the combustion air needed for sludge incineration。
As preferred technical scheme, described municipal sludge CIU also includes drying, with described vertical sludge, cyclone dust collector, air-introduced machine, dust collect unit by water and the carbon adsorption dust arrester that incinerator is sequentially communicated。
As preferred technical scheme, described municipal sludge CIU also includes the chimney being connected with described carbon adsorption dust arrester, the external air of described chimney。
The invention have the advantage that mud is performed twice at filter pressing by pressure filter one and pressure filter two by the present invention, obtain semi-dry sludge, reduce the energy expenditure of early stage sludge dewatering, alleviate the load of sludge incinerator, achieve the self-holding balance of mud to burn, also improve firing efficiency simultaneously。
