Background

The waste incineration is a traditional method for treating the waste, and the waste incineration method is one of the main methods for treating the urban waste because the waste is treated by the incineration method, the reduction effect is obvious, the land is saved, various pathogens can be killed, toxic and harmful substances are converted into harmless substances, and the heat energy generated by the waste incineration can be used for generating electricity.

The sack cleaner is the main dust collecting equipment of msw incineration power plant, and the sack cleaner includes the frame, is provided with a plurality of purification storehouses in the frame, and purification storehouse top-down has connected gradually dust removal storehouse and ash bucket, is provided with a plurality of sacks in the dust removal storehouse, is provided with the air-supply line and the play tuber pipe with the dust removal storehouse intercommunication in the frame, and the top of purification storehouse is provided with the apron, is provided with the lifting machine that the vertical lift switching purification storehouse of drive apron in the frame, and the upper portion of purification storehouse is provided with jetting device. The dust removal principle is as follows: the dust-containing gas enters the purifying bin after passing through the air inlet pipe, the gas passes through the cloth bag, the dust is retained on the outer surface of the cloth bag, and the purified gas is discharged through the air outlet pipe. Along with the extension of the filtering time, the dust layer on the cloth bag is continuously accumulated and thick, the resistance of the dust removing equipment is continuously increased, and when the resistance of the equipment is increased to a set value, the blowing device starts to clean the dust. Firstly, a lift valve of a dust removing bin is closed to cut off filtering airflow, then an electromagnetic pulse valve is opened, compressed air rapidly expands in the dust removing bin in a very short time and flows into a cloth bag, so that the cloth bag expands and deforms to generate vibration, and under the action of reverse airflow scouring, dust attached to the outer surface of the cloth bag is peeled off and falls into an ash bucket.

However, due to the temperature difference, dew can be condensed in the purification bin above the dust removal bin, and the flue gas contains corrosive gas, which can cause the purification bin to be corroded to generate rust slag. The traditional treatment method for the rust corrosion of the purification bin comprises the following steps: and opening the cover plate of the purification bin, and allowing the maintainers to enter the purification bin for manual cleaning. Therefore, secondary dust can be generated in the process of rust removal, and the dust remover is not clean in cleaning, long in cleaning time and low in cleaning efficiency.
