Description
Technical field
The present invention relates to flue gas ash removal technical field, particularly relate to a kind of mounting and positioning device for wet electrical dust precipitator rinse spray system.
Background technology
Wet electrical dust precipitator is a kind of for processing the cleaner containing trace dust and microparticle.Along with China's raising day by day to coal unit exhaust gas dust emission request, wet electrical dust precipitator is progressively applied in the exhaust system of flue gas；Wet electricity, by improving efficiency of dust collection, removes fine particle and SO effectively3Deng pollutant, to reach the performance indications of minimum discharge.
Spray system is also the maximum difference of wet type and dry electric precipitation device internal structure simultaneously.Wet electrical dust precipitator passes through spray system, with water in dust removal, positive plate is carried out water spray and washes away so that heavy collection dust on positive plate is scrubbed.For relatively dry electric precipitation device, because without ash removal equipment for flapping, wet type deashing can be avoided having trapped flying upward of dust, reaches the highest efficiency of dust collection.
Wet electrical dust precipitator parts are complicated, and installation requirement is more, and installation period is the longest.For ensureing that wet EFI drenches rinse-system coverage rate, spray system location must be precisely；Spray piping distance is longer, and when installing location, supporting steel frame deviation is relatively big, needs to have adjustment structure and reduces alignment error；When installing spray system, the overall anticorrosion of wet electricity is complete, and limits welding hot work.After wet electricity puts into operation, the thermal expansion of framework causes spray piping to produce displacement with fixing device, causes the deformation of spray piping.
Summary of the invention
It is an object of the invention to overcome prior art not enough, the installation and positioning structure of a kind of wet electrical dust precipitator spray system spray piping is provided, it is allowed to be applicable to on-the-spot narrow installation environment, reduce the alignment error of spray piping, all welding assembly complete in being operated in maker, on-the-spot can completing within a short period of time installs location, it is to avoid the fire operation after anticorrosion equipment is constructed, reduce the workload of construction and installation unit, improve work efficiency and installation accuracy.Reduce after wet electricity formally puts into operation, the spray system displacement caused because of support frame thermal expansion and deformation simultaneously.
For achieving the above object, present invention employs techniques below scheme:
This mounting and positioning device for wet electrical dust precipitator rinse spray system, including top side crossbeam, central frame back timber, limit casing, sleeve pipe and middle part connecting tube；Described top side crossbeam is two and is respectively arranged on central frame back timber both sides, and the top side crossbeam of side is fixed with limit casing, and the top side crossbeam of opposite side is provided with inlet tube and connects；Sleeve pipe is located on central frame back timber, and middle part connecting tube is located on sleeve pipe can fore-aft travel；Connecting tube rear and front end, middle part connects front shower and rear shower respectively；The other end of front shower connects in succession with inlet tube, and the other end of rear shower is connected with limit casing.
As preferably: the internal diameter of described limit casing is big compared with the external diameter of rear shower.
As preferably: the internal diameter of described sleeve pipe is big compared with the external diameter of middle part connecting tube.
The invention has the beneficial effects as follows:
1, a kind of wet electricity spray system mounting and positioning device: spray piping loads wet electricity middle frame top, and simple installation is quick, solid and reliable；
2, relatively other mounting means decrease the quantity of flange connector, alleviate installment work intensity.
3, in installation process, fine-tuning spray piping positions, it is achieved that flexible installing, decreases the installation infringement caused because of supporting construction position error, improves installation accuracy.
4, in installation process, it is only necessary to sleeve pipe bolt even, connects without welding fire operation, the safety of construction technology that increase is individual.
5, after installation, by positioner, whole shower leaves certain activity space, can reduce because of the pressure causing flange and bolt that expands with heat and contract with cold.

Detailed description of the invention
Below in conjunction with embodiment, the present invention is described further.The explanation of following embodiment is only intended to help and understands the present invention.It should be pointed out that, for those skilled in the art, under the premise without departing from the principles of the invention, it is also possible to the present invention is carried out some improvement and modification, these improve and modify in the protection domain also falling into the claims in the present invention.
As shown in Figures 1 to 5, this mounting and positioning device for wet electrical dust precipitator rinse spray system, including top side crossbeam 8, central frame back timber 9, limit casing 7, sleeve pipe 5 and middle part connecting tube 4；Described top side crossbeam 8 is two and is respectively arranged on central frame back timber 9 both sides, and the top side crossbeam 8 of side is fixed with limit casing 7, and the top side crossbeam 8 of opposite side is provided with inlet tube and connects 1；Sleeve pipe 5 is located on central frame back timber 9, and middle part connecting tube 4 is located on sleeve pipe 5 can fore-aft travel；Connecting tube 4 rear and front end, middle part connects front shower 3 and rear shower 6 respectively；The other end of front shower 3 connects 1 with inlet tube and is connected, and the other end of rear shower 6 is connected with limit casing 7.The internal diameter of described limit casing 7 is big compared with the external diameter of rear shower 6.The internal diameter of described sleeve pipe 5 is big compared with the external diameter of middle part connecting tube 4.
