A series of BS-780/930 type of dust collector:
I plant the production of dust collector of BS-780/930 series of Lurgi electric dust, is a new product of Lurgi company in 90s, is a company based in Lurgi dust BS780, according to the requirements of environmental protection, as well as the development needs of the market, after years of testing and research has achieved great success, BS930 optimization in the structure, more advanced in performance, reliable in operation.
Our company and the Design Institute of Baotou Steel, Shougang Design collaboration, the Lurgi technology successfully used in iron and steel enterprises according to practice in recent years the user proof, good application, BS series of electric dust collector in China's iron and steel enterprises kiln effect, won the majority of users.
Two, BS-780/930 series of electric dust precipitator work principle:
Electric dust collector is a device for collecting dust in flue gas by electrostatic purification method. Is an ideal equipment for the purification of industrial waste gas. Its purification work mainly depends on the electrode and the deposition of the two systems to complete. When the polarization between the high voltage DC input in the electrode space, produce anion and cation, and the role of the exhaust gas through the particle surface electrostatic field, under the action of electric field force to the electrodes move opposite, and deposited on the electrodes, dust to achieve. A device system has two poles when beating vibration, vibration hammer device periodically when the dust adhered thereto to be shaken off, fall into the lower hopper machine is discharged through the ash discharging device. The purified waste gas is discharged into the atmosphere by the outlet through the chimney, and the flue gas purification process is completed at this time.
Three, installation requirements:
The electric dust collector before installation must understand the electric dust collector layout, installation drawings and specifications, and in strict accordance with the implementation of drawings.
(a) manufacturing plant trial:
Combined discharge panels shall be assembled in the factory frame, assembled two diagonal diagonal length difference is not greater than 1/1000, the flatness is 10mm.
Suspension frame of each type discharge electrode is used for assembling steel bolts, the two diagonal difference of water is greater than the diagonal length of 1/1000 in suspension state when the frame height is less than or equal to 5m, the flatness is 5mm, when the frame height is larger than 5m when the plane is 10mm. The assembled frame shall be marked for the installation of the site.
The distribution of precipitation and transmission device, discharge electrode driving device, rotary discharger, bearings (ball type and slide type) shall be sent to the site after assembly.
(two) on site installation:
(1) before the installation, should check the size of the civil foundation, if not handled, the bearings installed in the base surface and leveling with a spirit level.
(2) according to the equipment list, check out of the box counting. The correction for the lifting and must be performed long-term stacking deformation caused by parts before installation. The main parts (such as the plate, corona wire and corona pole frame) were sampled, the manufacturing deviation of the design requirements should be corrected, such as can not be corrected, it should be scrapped.
(3) all parts of the electrode and the deposition system should be coated with special paint in the factory. This special paint is anticorrosive conductive paint, if you can not buy the use of kerosene and carbon black seasoning instead.
(4) cleaning of the transmission parts, refueling and other reference to my company's website or contact our company technical personnel
