Abstract
The utility model discloses a spray type flue gas desulfurization device. The device is composed of a spray devulcanizer with a spray device and a shower pipe and a rotational flow dehydrator, wherein, the spray device is arranged in an air inlet pipe and is connected with the lower shower pipe; the dehydrator is composed of a dewatering pipe and a rotational flow diverter arranged in the dewatering pipe. The flue gas entering the devulcanizer via the upper air inlet pipe is washed and desulfurized by the spray jetted in the shower pipe and enters the dehydrator, and then the flue gas is dehydrated and exhausted. The utility model has the advantages of small systemic resistance and high efficiency.
Description
The utility model relates to the boiler exhaust gas processing technology field, and a kind of specifically spraying fume desulfurizing device is applicable to the flue gas desulfurization of various boilers.
Industrial Boiler adopts the wet desulphurization device of desulfurization and dedusting one mostly at present.This device mostly adopts and installs in single tube monotubular cyclone dust collectors that a sieve plate that filters aqueous vapor realizes additional, upwards the sulfur-containing smoke gas that flows with filter through sieve plate spray and under gas-vapor mix, reach the purpose of washing desulphurization, discharge through a tangential sulphur dehydrator dehydration back of revolving again.This desulfurizer is because flue gas and aqueous vapor are counter motions, and what adopt is that tangential swirl dewaters, and causes SR big.
The purpose of this utility model is to release that a kind of desulfurization separates with dedusting.The flue gas desulfur device of the independent use that SR is little to realize the low-consumption high-efficiency desulfurization, improves the running quality of boiler.
Technical solutions of the utility model are as follows:
In desulfurizer, lay a vertical injecting type devulcanizer and a vertical axial eddy flow dehydrator.Devulcanizer is an injecting type devulcanizer of being made up of injector and drip washing pipe.Injector is made up of water injection pipe and shower nozzle, is contained in the vertical blast pipe, and the upper end of water injection pipe is connected with water pump, and the lower end is connected to shower nozzle, is connected with a drip washing pipe that is connected with circulating water pool in the bottom of blast pipe, and the shower nozzle of injector faces the drip washing pipe.Flue gas from top to bottom enters the drip washing pipe of devulcanizer, and the bottom of drip washing pipe is connected with dehydrator by tube connector.High velocity jet and under water need to mix mutually with the flue gas of co-flow in the birefringence of drip washing pipe door, fully contact is washed sulfur in smoke and fine dust and is removed.Dehydrator is made up of an air deflector and a dehydrating tube.Air deflector is made up of inner core, urceolus and flow deflector, is contained in the dehydrating tube, is connected with devulcanizer by tube connector.The inner core of air deflector is the tube of remaining silent, urceolus is a uncovered tube, flow deflector is housed between inner/outer tube, become flowing of rotation in order to the flue gas that contains aqueous vapor that will come by devulcanizer by straight up mobile, flow back to circulating water pool again thereby the sulphurous water stagnation of the circulation of vital energy in the flue gas is stayed on the inwall of dehydrating tube, guaranteed that flue gas after being purified discharged by the exhaust duct on top.In order to guarantee the abundant of desulfurization and dehydration, the shower nozzle of injector has adopted eddy flow and a loud-speaker type nozzle arrangements that is communicated with eddy flow, realizes the rotary-atomizing injection to guarantee water under high pressure, and fully washing absorbs sulfur in smoke.In order to realize eddy flow dehydration, the flow deflector of the utility model dehydrator is that to adopt 6 plate shapes be the blade of covering of the fan, along the circumferential arrangement tiltably-mounted between the air deflector inner/outer tube.
During use, the lower end of injecting type devulcanizer and eddy flow dehydrator is communicated with circulating water pool, the air inlet of devulcanizer upper end is connected on the exhaust outlet of deduster, and the upper end of dehydrator connects exhaust duct and gets final product.In order to reduce SR, the air inlet tube connector of deduster exhaust outlet and devulcanizer upper end adopts " ∪ " shape pipeline.
Below in conjunction with accompanying drawing the utility model is further explained:
