Problems solved by technology

[0004] In recent years, limited by the high operating cost of NaHCO3 absorption technology, there is almost no corresponding industrial application in China. There are few research reports on NaHCO3 injection and blending technology, and there are no mature industrial products to purchase. Relevant equipment must be developed to realize the technology. closed loop

Abstract

The invention discloses a sodium bicarbonate gathering, transporting and jetting complete technology system which comprises a powder conveying device and a powder metering device. The powder conveying device comprises a coarse powder cyclone separator used for separating coarse powder particles, the coarse powder cyclone separator is connected with a coarse powder pneumatic screw conveyor through a pipeline, and the coarse powder pneumatic screw conveyor is connected with an ultra-fine powder grinding machine through a vibrating feeder; and the powder conveying device further comprises a fine powder cyclone separator connected with the output end of the ultra-fine powder grinding machine, and ground ultra-fine powder meeting the standard enters a fine powder screw conveyor. The fine powder screw conveyor is used for conveying separated ultra-fine particles into a warehouse connected with the fine powder screw conveyor through a pipeline. The powder metering device is connected with the storehouse and is used for accurately metering powder flow, and metered powder enters a powder jetting device. Powder airflow jetted by the powder jetting device flows through a diffusion turbulent flow pipe and then is efficiently mixed with incoming smoke, and the smoke is purified. The mixing effect between the smoke and the powder is added, pollutants in the smoke are removed, and the purposes of energy conservation and emission reduction are achieved.

Description

technical field [0001] The invention relates to a sodium bicarbonate collection, transportation and injection complete process system, which completes the desulfurization and denitrification processes, and can effectively remove nitrogen oxides, sulfur oxides and other acid gases in flue gas, so that the purified flue gas can be discharged up to the standard. Background technique [0002] In recent years, due to the deteriorating domestic environmental conditions, energy-saving and emission-reduction technologies have been paid more and more attention by the state and have achieved vigorous development. NaHCO3 absorption technology is a highly efficient desulfurization and denitrification integrated technology. This technology can complete the desulfurization and denitrification process in one step, and is an integrated desulfurization and denitrification flue gas purification process. The process has a high removal rate of SO2 (>99.5%), SO3 (>99.5%), NOx (>98%), Me...
