Aesthetic sentences about the promenade.
A majestic dragon hovered in front of our eyes again, fixed eyes, it turned out to be a winding corridor, this corridor is antique, very good-looking. A gust of wind blew, and I seemed to hear the roar of a dragon; A ray of sunlight shone by, and I seemed to see the dragon showing off his stunt - the dragon tail swing. To say that this corridor is a dragon is really an image:
Based on a small and delicate pavilion, the pavilion is the dragon's head, and the crooked, nowhere of the corridor is the dragon's body, but the dragon's tail has always refused to show its face, like a shy girl covering her face with a veil. This is really "the dragon sees the head but does not see the tail"!
My favorite place is the promenade. The corridor is like a ribbon, the various scenic spots are closely connected, it is the longest corridor in the ancient buildings and gardens of our country, the corridor is also a beautiful gallery, each beam between the corridors is painted with colorful paintings, a total of more than 14,000 pieces, different. The color paintings are colorful, and the content is mostly landscapes, flowers and birds, and the plots of the four famous books.
It was also incorporated into the Guinness Book of Names.
What about the record! A majestic dragon hovered in front of our eyes again, fixed eyes, it turned out to be a winding corridor, this corridor is antique, very good-looking. A gust of wind blew, and I seemed to hear the roar of a dragon; A ray of sunlight shone by, and I seemed to see the dragon showing off his stunt - the dragon tail swing.
To say that this corridor is a dragon is really based on a small and exquisite, unique pavilion, the pavilion is the dragon's head, and the crooked, unknown corridor is the dragon's body, but the dragon's tail has always refused to show his face, like a shy girl covering her face with a veil. This is really "the dragon sees the head but does not see the tail"!
I stepped onto the promenade with curiosity. The corridor is so long that you can't see the end at a glance, and the top of the corridor has two hundred and seventy-three colorful intervals, and each interval is painted with colorful paintings.

The electrostatic precipitator of the second burning machine head was transformed in 2009. The original factory site is limited, only the location of the new dust collector on the east side of the original dust collector, and the other 1 needs to be newly built at the original dust removal location. Since the electrostatic precipitator of the sintering machine head is the best production equipment, in order to reduce the impact on the production time.
Construction plan: build a new dust collector in the open space on the east side, and connect the east flue to this dust collector for the first time after the dust collector is completed. Dismantle the original Dongtai dust collector and build another dust collector, after the dust collector is completed, the second contact will be connected to the west flue to the new dust collector, the second burner head electrostatic precipitator was completed at the end of 2009, and the design emission concentration of the dust collector is 50mg m3.
The electrostatic precipitator of the second and third burning heads can meet the new national standards under normal production conditions. However, the emissions of western burning and new burning cannot meet the requirements of the new national standards. Domestic and foreign sintering head flue gas purification all use electrostatic precipitator, the new national standard requires the emission to be less than 50mg m3, which is difficult to achieve at present, although the electrostatic precipitator increases to 4 electric fields, but the sintering head electrostatic precipitator is affected by the process temperature, humidity, specific resistance is fluctuating, and the emission of sintering head electrostatic precipitator is also fluctuating, especially the fluctuation of sintering production, sintering machine start-up and shutdown, etc.
At present, more than half of the sintering machines in the country have completed flue gas desulfurization, that is, the dust in the flue gas has been further processed by the desulfurization process after passing through the electrostatic precipitator, and the exhaust flue gas can fully meet the new national emission standards. According to the requirements of the national "Eleventh Five-Year Plan" emission reduction plan, the ironmaking plant began to adopt the Danish rotary spray semi-dry desulfurization process in 2009, and successively completed the flue gas desulfurization facilities of 6 sintering machines, and the dust emission of 6 sintering heads of the ironmaking plant after desulfurization bag dust emission of 30mg m3 fully meets the requirements of the new national standard. In order to meet the requirements of the new national standard of 30mg m3, the existing electrostatic precipitator can be increased and transformed
The first is to increase the circulation area, reduce the wind speed of the electric field, and prolong the residence time of the flue gas medium in the dust collector, which is equivalent to dismantling the existing dust collector and widening and heightening it on the original basis; The second is to increase the number of electric fields, the original dust removal is retained, and the original inlet or outlet bell mouth is removed and increased to an electric field, so as to increase the area of the dust collection plate of the electric field, prolong the time for the flue gas to stay in the electric field, so as to improve the dust removal efficiency; Another solution is the electric bag reform scheme: retain the original electrostatic precipitator foundation, shell, ash hopper, bell mouth and ash conveying system, only remove the plate line and rapping system of the original electric field, and remake the upper box to install the cloth bag, but due to the increased resistance of bag dust removal, the original motor needs to be increased. The above scheme is comprehensively considered from the stability, effect, investment, construction period, site, etc., and the electric bag modification scheme is the best.
