Embodiment Construction
[0017] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0018] refer to figure 1 , a gas dust removal and recovery device of the present invention, comprising a gasification cooling flue 1, a steam cooler 3, a bag filter 2, an induced draft fan 4, a muffler 5, a gas cooling tower 6, a Venturi tube 7, a gasification cooling flue The output end of the channel 1 is connected with the input end of the steam cooler 3, and the output end of the steam cooler 3 is connected with the input end of the bag filter. The working cover type steam cooler, the steam cooler and the steamer are integrated, and the steam cooling is carried out in the interlayer sealing cover of the steamer. The inner cover and the outer cover form a cooling chamber, and the center of the top of the cover is provided with an inner outlet and an outer outlet of the coolant. When the steam generated by the steamer enters the c...

Abstract
The invention discloses a gas dedusting and recycling device. The output end of a gas-cooling smoke channel is connected with the input end of a steam cooler, wherein the output end of the steam cooler is connected with the input end of a bag type dust remover; the output end of the bag type dust remover is connected with the input end of an induced draft fan; the output end of the induced draft fan is connected with the input end of a sound eliminator; the output end of the sound eliminator is connected with the input end of a gas cooling tower; the output end of the gas cooling tower is connected with the input end of a venturi pipe; a waste gas inlet pipe is arranged at the lower part of a shell; a waste gas outlet pipe is arranged at the upper part of the shell; a dust discharging pipe is arranged at the bottom of the shell; a nitrogen pulse jetting device is mounted at the upper part of the shell and is communicated with the inner cavity of the shell; a filter bag is mounted inside the shell; the bag body of the filter bag is made of a stainless steel fiber sintered felt; a polytetrafluoroethylene film is arranged on the surface of the stainless steel fiber sintered felt. By virtue of the gas dedusting and recycling device, the current problem of low dust cleaning efficiency is solved.
Description
technical field [0001] The invention relates to a coal gas dust removal and recovery device. Background technique [0002] A large amount of dusty gas is produced during converter blowing, its temperature reaches 1400-1600 °C, the CO content in the gas reaches 60-85%, and its calorific value reaches 7MJ / M 3 Above, due to the high gas temperature and CO content, it will burn immediately when it encounters air after it comes out of the furnace. Therefore, no matter from the aspects of environmental governance or energy recovery, it is necessary to effectively control the gas collection process in the process of recovering converter gas, try not to contact with air or burn as little as possible. [0003] Some converter steel mills at home and abroad use the gas to be combusted randomly and then released after cooling and dust removal. The disadvantage is that it not only pollutes the environment, but also wastes a lot of resources; The gas recovery method has disadvantages: s...
