Description
The present invention relates to a kind of device of removing pernicious gas such as sulfur dioxide in flue gas and micronic dust by the liquid hydro-peening.
Applied for the dust-removing desulfurating apparatus of Chinese utility model patent, its injecting type devulcanizer part mainly comprises cyclone, shower nozzle, water circulation system and the expansion joint that is arranged in the flue.Its deficiency is: cyclone is arranged on shower nozzle the place ahead, and flue gas at first forms swirling eddy in entering flue, and then through the liquid hydro-peening, flue gas for once mixes collision opportunity with liquid, and the reaction time between the two is short and insufficient, so desulfuration efficiency is lower; The spout of shower nozzle easily causes spout to stop up facing to the flow path direction that comes of flue gas stream.
The object of the present invention is to provide the high lateral spray type centrifugal desulfurizing and dedusting device of a kind of desulfuration efficiency.
Technical solution of the present invention is: by exhaust gases passes, be arranged on shower nozzle, cyclone in the passage, the lateral spray type centrifugal desulfurizing and dedusting device that expansion joint on the passage and water system are formed, the shower nozzle that its special character is to lean on passage air inlet end and is positioned at the one side, its spout is towards the opposite side relative with it, make liquid from the flue gas of passage one side injection stream through this section passage, cyclone is positioned at after the shower nozzle, is convenient to fully mix the liquid gas separation of collision and postorder.From the passage air inlet shower nozzle, cyclone and expansion joint are set at a certain distance successively to the gas outlet.Adopt the structure of this spread pattern, can make the flue gas that enters in the desulfation dust-extraction device passage, form and mix collision for the first time at first through liquid spraying.Then, both enter cyclone and form swirling eddy in mixing, realize mixing for the second time the collision of splashing, and quicken its chemical combination and decompose.At last, flue gas carries out realizing mixing the collision of splashing once more when liquid gas separates in expansion joint.Thereby improved desulfuration efficiency, and can further remove the micronic dust in the flue gas.
Described expansion joint, its exit is provided with water retaining brim, flows out to prevent the liquid in the expansion joint.Expansion joint can be provided with one or more, also is serially connected with the aqueous vapor release sleeve on passage, and it is made up of urceolus and the inner core that has connecting lever, its urceolus one end and channel connection, the other end is connected with flapper, is positioned at the inner core of urceolus, be provided with the water hole at the bottom of it, connecting lever passes outer tube wall and is connected with passage.
Desulfation dust-extraction device of the present invention normally is used with deduster, with pernicious gases such as removal sulfur in smoke, it can be serially connected between deduster and the air-introduced machine, perhaps between deduster air-introduced machine and the chimney, and can utilize between the two flue as the passage of desulfation dust-extraction device, therefore need not set up floor space.Desulfation dust-extraction device can be a vertical structure, also can be horizontal type structure.
The present invention compared with prior art has following characteristics: reasonable in design, flue gas make it fully mix collision with liquid through spray, eddy flow, this three phases that expands, and the chemical combination that has quickened sulfur dioxide decomposes, and has improved desulfuration efficiency.Add an amount of calcium hydroxide in liquid, its desulfuration efficiency is more than 70%.Utilize the passage of the smokejack of deduster, need not set up floor space as this device.Spray liquid recycles, and saves the water source.
Fig. 1 is the structural representation of vertical side spray centrifugal desulfurizing and dedusting device.
Fig. 2 is the structural representation of horizontal side spray centrifugal desulfurizing and dedusting device.
Be described in further detail below in conjunction with accompanying drawing:
As shown in Figure 1, vertical side spray centrifugal desulfurizing and dedusting device is made up of exhaust gases passes (1), shower nozzle (2), cyclone (3), expansion joint (4), (5), (6), aqueous vapor release sleeve (7) and water system.It is arranged between deduster (8) and the deduster air-introduced machine (9), and the flue that is interconnected between deduster and the air-introduced machine is the passage of desulfation dust-extraction device, and it adopts metal material to make the pipe of circular pipe type rectangular tube or other shape.Be provided with opening by on the conduit wall of air inlet end, it is connected with shower nozzle sleeve (10), and shower nozzle is fixed in the sleeve, and its quantity can be determined as required, the spout of shower nozzle is towards the sidewall relative with access portal, shower nozzle will from passage one side from top to bottom injection stream through the flue gas of this section passage.The cyclone that is positioned at below the shower nozzle is made up of one group of helical blade, and it is fixed on the vias inner walls.Two expansion joints are set, the passage that it increases gradually for interior aperture on one section passage below cyclone.Be connected with drainpipe (12) on expansion joint, after containing liquid smoke gas and entering expansion joint, swirling eddy is thrown to the expansion joint inwall with liquid, and in drainpipe is delivered to water tank in the water system, with use to be recycled.Flue gas is then discharged from expansion joint.Be circumferentially with water retaining brim (11) on edge, expansion joint exit, in case liquid flows in the hypomere passage.Be connected with the aqueous vapor release sleeve below expansion joint, it is made up of urceolus and the inner core that has connecting lever.The upper/lower terminal of urceolus is a conically shaped, and the middle part is a cylinder, and the top of urceolus is connected with the expansion joint above it, and the bottom is connected with flapper (13).Liquid in this separation will be discharged from flapper.The inner core coaxial with urceolus, its bottom is provided with the water hole, is convenient to discharge opeing.Connecting lever passes urceolus and is connected with air-introduced machine through passage, and gas will be expelled to air-introduced machine from the inner core connecting lever.Do not enter air-introduced machine in order to ensure liquid, so on the passage before the air-introduced machine inlet expansion joint (6) is set again, so that water, gas thoroughly separate, the drainpipe of this expansion joint (14) can be connected the urceolus lower end of aqueous vapor release sleeve, and liquid will be discharged from flapper.The exit of this expansion joint is along circumferentially being provided with water retaining brim (15), and the water system of this device is a water circulation system.It is by water tank, water pump, water valve and water inlet pipe, compositions such as drainpipe.
Fig. 2 is horizontal side spray centrifugal desulfurizing and dedusting device, and it is arranged between deduster air-introduced machine (1) and the chimney (2).Setting gradually shower nozzle (4), cyclone (5) and two expansion joints (6) (7) in the passage (3).Water system is a water circulation system.Because the outlet of this device directly is connected with chimney, and is not really high to the aqueous vapor separation requirement, therefore the aqueous vapor release sleeve need be set and increases expansion joint.
When the flue gas through dust removal process enters in the passage of desulfation dust-extraction device, at first through liquid spraying, form swirling eddy through cyclone then, make it fully mix collision, decompose to quicken chemical combination, swirling eddy is after entering expansion joint and aqueous vapor cylinder, and liquid will be thrown to tube wall, and use to be recycled in drainpipe is sent into water tank, slough the flue gas of sulfur dioxide and will discharge from chimney.
