Bag filter, slag, Raymond mill dust collector

The dryer fiberglass bag filter can change the bag without stopping the compartment. It is simple, reliable and low in operating cost. It is a high-temperature flue gas dedusting device. It has been serialized and is suitable for submerged arc furnace, calcium carbide furnace and rotary kiln. Purification of high temperature and high humidity bodies such as kiln tail. The purified gas passes through the bag filter chamber, passes through the exhaust valve of the top of the device through the exhaust fan, and is discharged into the atmosphere through the exhaust pipe. The dust in the filter bag is continuously increased, and when the resistance rises to a prescribed value, the cleaning is started. The cleaning method of the device relies on the single-chamber anti-air blowing method. When the air blows back, the reversing valve is closed, the exhaust pipe is closed, the anti-drying pipe is opened, and the exhaust of the single chamber is cut off. Because the inlet ducts of the various chambers of the equipment are in communication and are in a negative pressure state, due to the suction of the adjacent chamber. The airflow is passed through the anti-blowing tube to the filter bag chamber, and the filter bag is passed through. The airflow enters the inner side from the outside of the filter bag, and is discharged through the ash hopper and the air inlet pipe of the chamber, and the filter bag is sucked. The dust inside the filter bag is shaken down to the falling ash bucket, and the single chamber is cleaned. The remaining chambers are cleaned in the same order under the control of the cleaning actuator. When a certain value is obtained, The cleaning stops. The number of filter bag arrays is 1000M2, which is the number of rows in the 2W2 arrangement; the M2 is the number of rows in the 2W4W2 arrangement.

The dust on the cloth bag of the dust collector of the slag slag slag Raymond mill uses the compressed air to clean the dust regularly, which reduces the accumulation of dust. The design of the process of the biomass boiler dust collector: the dust removal process can be divided into two sets to separate Processing, divided into 3T and 6T for processing. (1) The smoke generated by the 3T boiler first enters the cyclone dust collector for treatment, and the treated soot dust enters the bag filter to perform secondary treatment. After being exhausted by the chimney into the atmosphere. During the period, the 6T boiler dust removal system is turned off. (2) The smoke generated by the 6T boiler first enters the cyclone dust collector for treatment, and the treated soot dust enters the bag filter to perform secondary treatment. After being exhausted by the chimney into the atmosphere. During the period, the 3T boiler dust removal system is turned off. (3) Due to the large fluctuation of flue gas at the boiler outlet, an electric mixing valve is installed at the front end of each cyclone dust inlet to avoid burning the bag due to excessive temperature inside the dust collector. working principle:
