Automatic Management of Waste Produced During Installation and Commissioning of Flue Gas Desulphurization Systems in Thermal Power Station
FIELD OF THE INVENTION
Our Invention is related to an automatic management of waste produced during installation and commissioning of flue gas desulphurization systems in a thermal power station. BACKGROUND OF THE INVENTION
The flue gas desulfurization in a thermal power plant generally adopts a wet desulfurizing process. The technological principle of a wet desulfurizing process is to make flue gas enter the absorption tower of desulfurization, as it contacts with the absorption liquid, which is limestone CaCO 3, from slurry pool suspension, the sulfur dioxide SO2 in flue gas reacts with limestone and generates Ca(HSO 3 ) 2 precipitate, transported outwards.
Mixed plastic wastes usually contain, valuable materials in part firmly connected, as well as impurities apart from a large number of different types of plastics.
Although many individual process steps for the recycling of such plastic waste are known in the prior art, such as the mechanical milling of the plastic waste into a ground material or the separation of two components using sink-or-float separation or utilizing the new near-infrared separation technique. The known methods are loaded with the drawback of high separation selectivity, which is a pre-requisite for obtaining plastics of high and constant quality, limiting their use in homogenous plastic wastes and making them unfit for mixed plastic wastes.
For sustained recycling, it is necessary to separate the individual materials in a manner that is graded as pure as possible, so that they may successfully replace new goods free from impurities in markets segments and can therefore contribute significantly, both to the competitiveness of the end products as well as to the preservation of resources.
If the mixed plastic waste, for example, rejects from liquid cartons for drinks such as milk, fruit juice, or suchlike, which upon separation of the paper fibers become available for cardboard production in the paper-mill, then films, laminated films, hard plastic parts, and residual paper fibers are contained in this mixed plastic. The films predominantly comprise low-density polyethylene (LDPE), the laminated films comprise aluminum foil and LDPE film, and the hard plastics from the lips and closure caps comprise high-density polyethylene (HDPE), and to a lesser extent, polypropylene (PP). Moreover, such drink cartons also contain a quantitatively negligible proportion of film strips of polyamide (PA) or polyethylene terephthalate (PET), which are used to seal the line joints.
OBJECTIVES OF THE INVENTION
1. The objective of the invention is a circulating water and flue gas combined treatment system for a thermal power station, applied in an energy-saving and emission-reducing scheme within the power station. 2. The other objective of the invention is a raw water treatment device for circulating water and a flue gas desulfurization treatment system for treating flue gas. The raw water treatment device is added with lime and provided with a precipitating tank-1, which is connected to a concentration tank-2. 3. The other objective of the invention is a concentration tank-1, connected with the flue gas desulfurization treatment system through a slurry pump and a slurry transporting pipeline, the flue gas desulfurization treatment system is connected to a precipitating tank-1. 4. The other objective of the invention is a circulation system including a raw water treatment classification and a wet-process flue gas desulfurization treatment system in the thermal power station, combined for enabling a discharged slurry waste from the circulating water treatment to be used in the flue gas desulfurization so that costs in treatment and outward transportation of limestone slurry are reduced. 5. The other objective of the invention is saving the cost of raw materials in the flue gas desulfurization treatment system, thereby achieving targets of waste recycle and energy saving, with emission reduction. 6. The other objective of the invention is the installation for separating individual valuable materials from mixed, milled, plastic wastes, comprising film parts, laminated film parts, and hard plastic parts, plus optional impurities. 7. The other objective of the invention is to separate forms of plastic waste. The plastic waste is separated into hard plastics and films as well as laminates, and finally, the hard plastics are categorized and recovered into different types of plastics.

The present invention improves the effectiveness and performance of the waste treatment system by connecting the concentration basin I to the slurry pool of flue gas desulphurization system with slurry transportation pipeline by slush pump.
The present invention improves the performance of sedimentation basin II many folds and is renamed as the concentration basin II, which uses transpiring moisture after the precipitation is full.
The problem underlying the invention is to provide methods and an installation for separating individual valuable materials from mixed, in particular milled, plastic waste comprising films, laminated films, hard plastics, plus impurities, wherein the valuable materials including any metal components that may be present from plastic-metal composites can be recovered from the waste comparatively cost effectively with a high degree of separation selectivity and purity.

FIG. 1 shows the first part of a flow diagram of the first embodiment of the method according to the invention.
FIG. 2 shows the second part of the flow diagram of FIG. 1.
FIG. 3 shows the third part of the flow diagram of FIG. 1.
DESCRIPTION OF THE INVENTION
The description of the method according to the invention is made using a non limiting example of the recycling of liquid cartons, referring to the first parts of FIGS. 1 to 3, the technical details being transferable to all the methods and installations according to the invention.
Milled plastic waste comprising shredded liquid cartons is fed to the process, see the first step in FIG. 1. This ground material or reject essentially comprises plastic films, laminated films of aluminum and polyethylene (Al/PE films), hard plastics such as HDPE and PP closures, small quantities of paper fibers, small quantities of technical plastic films such as polyamide and PET, as well small quantities of impurities such as metal particles, textiles, sand, etc.
According to the invention, a dry-mechanical separation of the residual paper fibers from the plastics takes place in next step. For this purpose, a grinding device is employed, which either comprises a friction centrifuge known to the person skilled in the art or a modified hammer mill, the sieve hole size whereof can be selected such that the palm-sized reject films are isolated, but not reduced in size. In the case of the friction centrifuge, the operation is preferably carried out wet, i.e. liquid is added to the rejects to prevent overheating of the ground material. At the same time, this liquid assists in removing the small impurities, such as paper labels, paper fibers, and sand, etc. through the slots of the horizontal centrifuge casing cylinder. In the case of the hammer mill, an airflow, which is blown through the hammer mill, carries all the light impurities out of the system to the air filters. In the case of the friction centrifuge, cleaning can be carried out dry, but also wet, i.e. with the addition of washing medium. In the case of the hammer mill, the operation is carried out solely in a dry manner.
The ground material originating from the previous step is fed to the next step, wherein the ground material is divided into a light fraction and a heavy fraction using air sifting, for example in a known zigzag sifter.
All the particles which are carried out upwards by the airflow at the adjusted airspeed are removed with the light fraction. As a rule, there are all the film particles (LDPE and Al/PE films), but they can also include individual paper shreds, individual paper fibers, cork, and EPS particles as well as small ground material particles from the fraction of the hard plastics. The light fraction is further processed in the next step of FIG. 1, which is dealt with in FIG. 2.
The heavy fraction contains most of the hard plastics, heavy impurities (e.g. metal particles, textiles, minerals, small wood particles) as well as undissolved paper fiber lumps, which pass through a hammer mill whose sieve plate holes are large enough. Once separated from the light fraction, the heavy fraction is further processedin the nextstep ofFIG.1.
In next step, interfering, exclusively heavy impurities are first separated from the heavy fraction, to separate only hard plastics for further processing. There are several possibilities regarding the tool for this impurity separation. A suitable instrument for this task is the so-called ballistic sifter. A second possibility is also offered at this point by the zigzag air sifter, the airspeed whereof is adjusted in this case such that only the hard plastics are removed as a light fraction, but not the impurities. A third possible aid for this task is also a sink-or-float separation. Further machines that may be suitable are known to the person skilled in the art.
A following sink-or-float separation of the hard plastics, which is preferred here, exhibits optimum separation selectivity, in particular with the following considerations.
The particle density of plastics is made up of the densities of its components and their fractions in the given plastic, once any possible vacuoles are disregarded. Components of the plastic are its polymer as well as the fluctuating additives/admixtures, which can vary from manufacturer to manufacturer and over time. Besides, new types of plastic with new densities may be used by the manufacturer without warning. According to the invention, therefore, use is not made of a predetermined or theoretically determined constant density with which the pile of ground material particles can be separated from hard plastics of the rejects.
Instead, an optimum density for the separation medium is determined empirically in next step, and more precisely at least at the start of the separation, to obtain the greatest possible purity of the two fractions to be separated.
