The specific embodiment
Below in conjunction with accompanying drawing and embodiment, the specific embodiment of the utility model is described in further detail.Following examples are used to explain the utility model, but are not used for limiting the scope of the utility model.
As shown in Figure 1; A kind of dry method dust wet method multi-tube dusting desulfurization vortex composite set comprises the dry method ceramic multicyclone dust collector 1 and wet method multi-tube dusting desulfurization vortex tower 2 that link together, and the sidepiece of dry method ceramic multicyclone dust collector 1 is provided with smoke inlet 11; The inside of dry method ceramic multicyclone dust collector 1 is provided with ceramic cyclone body and flow deflector (not shown); The top of dry method ceramic multicyclone dust collector 1 is provided with exhanst gas outlet 12 and is communicated with wet method multi-tube dusting desulfurization vortex tower 2 through flue 3, and said wet method multi-tube dusting desulfurization vortex tower 2 is made up of granite multitube double shell, and double shell comprises first cylindrical shell 21 and second cylindrical shell 22; The top of first cylindrical shell 21 is provided with jet pipe, nozzle 2101; Be provided with in the desulfurization chamber that is provided with wet method multitube 2103, the first cylindrical shells 21 bottoms below jet pipe, the nozzle 2101 between alkali lye jet pipe, spray nozzle device 2102, the first cylindrical shells 21 and second cylindrical shell 22 through centrifugal swirler 23 connections; The top of second cylindrical shell 22 is provided with exhanst gas outlet 24; The middle part of second cylindrical shell 22 is for falling fog chamber 2201, and the top that falls fog chamber 2201 is provided with demister 2202, and the bottom that falls fog chamber 2201 is provided with centrifugal from post 2204 and jet pipe spray nozzle device 2203.
The operation principle of the utility model is following:
Dry method; Gas gets into the distribution of gas chamber by total inlet pipe, gets into the annular space between ceramic cyclone body and the flow deflector subsequently, and flow deflector makes gas become circular motion by rectilinear motion; The overwhelming majority of swirling eddy is downward twist from cylinder along cyclone body; Flow towards cone, dusty gas produces centrifugal force in rotary course, the grit of density greater than gas got rid of to barrel.Grit is contacting with barrel, just loses inertia force and leans on the momentum of entrance velocity and downward gravity to get into total ash bucket along wall to falling into ash discharging hole.When the outer rotational gas flow that rotation descends arrives the cone lower end position; Because of the contraction of cone promptly with same direction of rotation the tornadotron axis direction shape flow (pure qi (oxygen)) of from bottom to top continuing to spin; Get into exhaust chamber through ceramic cyclone body blast pipe; Discharged by total exhaust outlet, total air escape pipe can be placed on side direction or top as required.
Wet method, flue gas is provided with one group of high-pressure nozzle after getting into the wet method device at the upper inlet place; When the dust constaining band of gas a large amount of water along high velocity air process wet method multitube; Multitube trunnion top all is provided with the jet pipe nozzle, and (P >=3kg) fully mixes cigarette G&W or alkali lye water and obtains first class purification to spray into the wet method multitube from nozzle; After the purification not the flue gas of dust-laden go out from multitube; Flue gas is through multitube bottom desulfurization chamber, through the jet pipe spray nozzle device, passes through cylindrical shell bottom overfall remittance sedimentation basin circulating and recovering through the washing back with buck after flue gas separates.The flue gas that obtains double purification is turned back 90 ° from inner core to urceolus gradually, tangentially, in inner tube wall bottom and outer tube inner wall one group of centrifugal swirler is set, and one group of supporting high-pressure nozzle.Turn back when the centrifugal swirler from inner core when flue gas, just in time mixes with shower water, neutralize with shower water again, obtain three grades of purifications, buck imports sedimentation basin through the device bottom through overfall.
Go out the flue gas of centrifugal swirler, three grades of purifications, the flue gas of this moment produces high speed centrifugation, turns back 90 ° again, under action of centrifugal force, is close to the outer tube inner wall high-speed screw and rises.The urceolus bottom is provided with centrifugal from post, and the jet pipe nozzle is housed, and moisture film from top to bottom gets off along outer tube inner wall and fully contacts with spiralling flue gas, makes injection diffuse into vaporific gas-liquid mixed, again through the moisture film washing, thereby removes tiny grit and a spot of SO
2, the 4th road that carries out flue gas simultaneously purifies, and imports dull pond circulating and recovering through the device bottom through overfall with waste water after flue gas separates.
This moment, spiralling flue gas also had centrifugal force, and under action of centrifugal force, air-flow is through falling the fog chamber; Top is provided with demister, and air-flow goes out through fan type demister upper and lower surface, and demister has many rounds; The rinsed device is equipped with on top, aqueous vapor and along the round of demister to around diffusion, after the demister aqueous vapor is separated; Pure qi (oxygen) is from bottom to top discharged to gas outlet, cylindrical shell top, and waste water flows to the device bottom through outer tube inner wall, goes into sedimentation basin through overfall again.
All waste water all collect in sedimentation basin, thoroughly separate with the dedusting lime-ash, and deposition clarification back reuse, water system needs only additional running water in a small amount and both can.The slag periodic cleaning is through flue gas atmosphere that enters up to standard behind the dehydrating demisting of device top of two-stage dust removal process and level Four purified treatment.
The above only is the preferred implementation of the utility model; Should be understood that; For those skilled in the art; Under the prerequisite that does not break away from the utility model know-why, can also make some improvement and modification, these improvement and modification also should be regarded as the protection domain of the utility model.
