The design of the ash bucket should consider opening a hole so that people can put ash into the ash bucket and wear a dust mask when working in the ash bucket. Dust-removing method of dust removal at the bottom of the cage filter bag: gas cleaning: Gas cleaning is the use of high-pressure gas or external atmosphere to blow the filter bag to remove dust on the filter bag. Gas cleaning includes pulse jet cleaning, reverse blow cleaning, and reverse suction cleaning. Mechanical vibration cleaning and ash removal: The top of the machine is used for rapping dust cleaning at the top and rapping and dust removal in the middle. It is the use of a mechanical rapping device to periodically beat each row of filter bags in order to remove the accumulated dust on the dust bag. The dust bag cage material is made of 20# carbon steel, and the skeleton production line is used for forming once to ensure the straightness and the degree of distortion. The filter bag frame is smooth and burr-free after touch-welding, and there is enough strength to prevent welding, no welding, and welding. Solder leakage phenomenon. The longitudinal reinforcement and anti-span ring of the bag cage are evenly distributed, and have enough strength and rigidity to prevent damage and deformation. The top is equipped with a cold stamping short pipe to ensure the verticality of the bag cage and protect the filter bag mouth during the spraying. Safety. Using galvanized technology, the coating is firm, wear-resistant and corrosion-resistant. It avoids corrosion of the surface of the skeleton and the binding of the filter bag after the dust collector has worked for a period of time. This ensures smooth bag replacement and reduces the damage to the bag during bag replacement.
The dust collector bag cage has a large processing air volume, strong load adaptability, and a ceramic movement that is smooth and durable, does not cause clogging, and has a small footprint. It can be installed flexibly according to the user’s site condition and be placed indoors and outdoors. can. The dust collector frame is used for the dust management of industrial boilers and thermal power plant boilers of various models and various combustion methods. Dust bag cages can remove gases of different forms and functions, and will not cause major damage to the dust bag cages and the function can not guarantee the value and role in use, and ensure that they can fully display important functions and values. In dust removal work 25 ~ 35 °C, in order to ensure the good use of filter bags. If far-infrared electric heaters and electric heaters are installed in the precipitator, or if additional radiators are installed in the bag room, the temperature of the host air can be appropriately increased. Dust bag cages are used in different industries. They play an important role in the industry according to their own characteristics and their advantages. Dust is removed according to different conditions to ensure the cleanliness and sanitation of the environment. Strengthen the temperature monitoring of the dust collector and dedusting system so as to grasp the premise of the use of the bag filter and prevent condensation. The dust-laden gas should be evenly distributed in the dust collector to prevent eddy currents from escaping at corners to reduce the amount of gas passing through. The problem of condensation occurs due to local low temperatures.
