Description
Technical Field
The utility model belongs to the technical field of atomizing disk, concretely relates to atomizing disk guiding disc and atomizing disk.
Background
Atomizing disk: the atomizing disc is a key component in a waste incineration power generation device, namely a flue gas deacidification atomizer, and atomizes lime slurry into 30-50 mu m-level liquid drops through high-speed rotation, so that the lime slurry and acid gas in the flue gas are subjected to neutralization reaction to play a role in deacidification. The atomizing disk is arranged at the bottom of the rotary atomizer (according to the working state). A guide block: and a part which is positioned between the upper disk and the lower disk of the atomizing disk and is directly contacted with the lime slurry. When the atomizing disk rotates at high speed, the lime slurry is distributed by the guide block and moves to the edge of the disk along 18 channels in the guide block at 8000-. Because the atomizing disk rotates at a high speed, lime slurry directly scours the guide block and the upper and lower disks of the atomizing disk, and the atomizing disk is greatly abraded.
The traditional atomizing disk structure comprises an upper disk, a lower disk and 18 guide blocks which are uniformly distributed between annular surfaces formed by the upper disk and the lower disk. Under normal operating mode, because atomizing disk's rotational speed is very fast, consider the cost, atomizing disk upper disk, lower wall are different with the material of guide block, and wherein the material of guide block is more expensive, harder, more wear-resisting. And small gaps exist between each guide block and the upper disc and between each guide block and the lower disc, and under the condition that the atomizing disc rotates at a high speed, lime slurry can corrode, scour and abrade the upper disc and the lower disc of the atomizing disc, so that the gaps between the guide blocks and the upper disc and between the guide blocks and the lower disc are larger and larger. When the corrosion and the abrasion are uneven, the atomizing disc loses the dynamic balance, thereby failing.
The atomizing disc is a key part in a flue gas deacidification atomizer in the waste incineration power generation equipment, polluted flue gas from a household waste incinerator enters a reaction tower, then the atomizer is rotated to spray atomized water-cooled flue gas into a tower body, and meanwhile, acid gas in the flue gas and sprayed lime slurry are subjected to neutralization reaction.
Lime slurry and process water are fed into the atomizer, at the bottom of which the lime slurry is fed evenly into the rotating spray disk. In the atomizing disk, the lime slurry is accelerated by the distribution block, and a layer of uniform mist is formed around the atomizing disk by the centrifugal force generated by the atomizing disk rotating at high speed. The mist of the lime slurry layer has a larger contact reaction surface with the flue gas.
The domestic existing atomizing disk is continuously designed abroad, and is optimized and improved on the basis of the design. The structure of the device is mainly divided into three parts: the upper tray body, the lower tray body, the distribution block, and fasteners such as bolts, connecting shafts, screws, gaskets and the like. The upper base and the lower base are made of Hastelloy, and the middle wear-resistant block is made of hard alloy. The distribution block and the gaskets are uniformly distributed between the annular surfaces formed by the upper tray body and the lower tray body, and the distribution block and the gaskets are fixed by nine bolts and nine connecting shafts. After the assembly is finished, finish machining is still needed, and a dynamic balance test is carried out on the atomizing disc.
The traditional atomizing disc structure comprises an upper disc, a lower disc and distribution blocks which are uniformly distributed between annular surfaces formed by the upper disc and the lower disc. The Hastelloy adopted by the upper disc and the lower disc of the atomizing disc has low hardness and poor scouring resistance, so that the atomizing disc is quickly out of service, the service life is only about six months, and the cost of the waste incineration equipment is greatly increased. The 18 guide blocks are fixed by connecting shafts and bolts, and a small gap is inevitably formed. These clearances affect the dynamic balance of the atomizing disk on one hand, and on the other hand, the dynamic balance of the atomizing disk is washed by lime slurry under the high-speed rotation of the atomizing disk, so that the atomizing disk is worn and corroded, and the atomizing disk fails. When the traditional atomizing disk is assembled, 18 guide blocks, 9 connecting shafts and 9 bolts are weighed and then reasonably arranged according to the weight of the traditional atomizing disk to obtain the optimal balance. But this optimum balance is difficult to grasp. Traditional atomizing disk uses gluey bonding when the top of guide block and bottom installation gasket to reach the installation screw and need use screw thread fastening to glue. The amount of glue also affects the dynamic balance of the atomizing disk. In the traditional atomizing disk processing and manufacturing process, the processing technology is multiple, and the assembly procedure is complicated.
Therefore, it is necessary to develop a new guiding disc and an atomizing disc to solve the above problems.
