Background
As one of key industries in the field of industrial pollution control in China, the glass industry breaks through 2000 glass production lines at present, and the dust emission amount per year reaches tens of thousands of tons. Because petroleum coke has high heat value and low price, in order to reduce the production cost of glass enterprises, the fuel used by the glass production line at present tends to be changed from original heavy oil to petroleum coke. The high-viscosity dust discharged by the glass melting furnace burning petroleum coke flue gas is a problem which needs to be solved urgently in the glass production discharge. The dust in the burning petroleum coke flue gas contains a large amount of alkali metals, and if the kiln flue gas is directly denitrated, the dust will greatly reduce the activity and the service life of the catalyst, and is not beneficial to the denitration and stable operation. It is therefore necessary to arrange a dust collector at the front end of the denitration device.
At present, optional equipment for treating dust in high-temperature flue gas of a glass kiln comprises an electric dust remover and a bag type dust remover, and because petroleum coke flue gas discharged by the glass kiln has the characteristics of high temperature, fine dust, high alkali metal content, strong corrosivity, strong hygroscopicity, low specific resistance, high viscosity and the like, when the electric dust remover removes dust from the petroleum coke flue gas, various problems of dust adhesion, part damage, low dust removal efficiency and the like occur.
Although chinese patent No. 201410616155.8 and publication No. CN104289086A disclose a method and apparatus for removing high concentration dust in flue gas of glass kiln, the method and apparatus treat viscous dust by an electric dust collector after tempering, thereby improving the properties of dust and reducing the viscosity.
But the problems of insufficient mixing of the modifying agent and the dust in the flue gas and the like, secondary dust raising, incapability of removing PM2.5 fine particles and the like exist. And conventional sack cleaner can't operate under the high temperature condition, even adopt the high temperature filter material, life is usually no longer than a year, and often has the risk of scaling loss, jam, and the operating pressure drop is great, and simultaneously, the high viscosity dust is stuck with paste the bag easily and is leaded to whole system destruction, and the running cost is very high, can not satisfy user's needs.
