What is injection pressure? The injection pressure: the pressure at which the pulse valve is opened and the compressed air is injected into the dust collector. The higher the blowing pressure, the faster the blowing speed and the better the cleaning effect. After the pressure drop of the bag filter is limited, the higher the injection pressure, the greater the processing...
Hygroscopic deliquescent dust Hygroscopic and deliquescent dusts such as CaO, Na2CO3, NaHCO3, NaCI, и т. д.. are easy to absorb moisture and harden on the surface of the filter bag, or become viscous liquid after deliquescence. It will cause difficulty in cleaning, large pressure loss, and even force the dust collector to fail. When dealing with hygroscopic and deliquescent dust, the following should be...
Precautions for daily operation of pulse dust collector (1) When the dust collector installation is working normally, the ash discharge cannot be stopped. Avoid dust accumulation in the hopper and force the dust collector to stop. Smoke and ash from the exhaust port indicate that the filter bag has been leaked. If any filter bag mouth is found to have dust...
1. Particulate Matter Control The flue gas from the cooling tower is neutralized by the slaked lime and activated carbon injection system, and then enters the bag filter and is discharged from the top of the compartment. The injected activated carbon and other particulate matter adhere to the surface of the filter bag to form a layer of filter cake; the...
1 Conditions of explosion 1.1 pulverized coal temperature Different coal types have different ignition temperatures, but for finer coal powder, due to the increased specific surface area, the explosion temperature is much lower than its ignition point. Usually the ignition temperature is below 40 ℃. 1.2 Volatile matter of pulverized coal The combustible gas produced by the heating of pulverized coal is burned before...
Introduction to cement mill condensation examples 1 Example of high temperature type mill The cement mill with a diameter of 4.5m × 12.96m in a factory is a circular flow mill with a cyclone separator, and the end of the mill is dedusted by a flat-bag type dust collector. The mill system is indoors, the air convection between the mill and the...
Industrial electric furnace classification: Resistance furnace, induction furnace, vacuum furnace, electron beam furnace, heat treatment (or smelting) unit, heat treatment auxiliary equipment, combustion furnace. Industrial electric furnace dust removal mainly uses bag filter, and the dust hood is designed according to different working conditions on site. Поэтому, the difficulty of industrial electric furnace dust removal lies in the design and arrangement of...
At 17:58:50 on September 14, 2003, an explosion occurred during the trial production of the TGM1500 air-box pulsed bag filter, a pulverized coal preparation system for a 2500t/d clinker production line in a factory. Accident analysis believes that this is caused by unreasonable process design. The process layout was improved afterwards. This paper introduces the occurrence process of the accident,...
