Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Accompanying drawing is the structural representation of the utility model embodiment.
The specific embodiment
As shown in drawings, a kind of high-temperature flue gas comprehensive treatment equipment, comprise the heat exchanger 2 that is connected with high-temperature flue gas passage 1, the inertial dust separator 3 that is connected with the outlet flue of described heat exchanger 2, with the wet scrubber 5 that the outlet flue of described inertial dust separator 3 is connected by connecting pipe 4, the moisture separator 6 that is connected with the gas outlet of described wet scrubber 5.
Described heat exchanger 2 is made of gas heat exchanger, and this gas heat exchanger is provided with air inlet that is connected with blower fan and the air outlet that is connected with the casting smelting furnace.
The housing of described wet scrubber 5 is the cylindrical shape of sealing, be provided with filter course 53 in the described wet scrubber 5, described filter course 53 is separated into upper and lower two parts with the inner space of wet scrubber, described connecting pipe 4 stretches in the wet scrubber 5 from described lower space, the outlet flue 42 of described connecting pipe 4 is towards the bottom of wet scrubber, outlet flue 42 flares, the gas outlet of described wet scrubber 5 is arranged at the top.
Be provided with first atomizing sprayer 41 that can spray treatment fluid in the described connecting pipe 4, described connecting pipe 4 tilts, and the position of its smoke inlet is higher than the position of its outlet flue.
Near the outlet flue of the bottom of described wet scrubber 5, connecting pipe 4, be provided with second atomizing sprayer 51 of downward spray treatment fluid.
Near the bottom of described wet scrubber 5, filter course 53, be provided with the 3rd atomizing sprayer 52 of downward spray treatment fluid.
Be provided with the cleaning spraying device 54 of downward spray water purification on the top of described wet scrubber 5.
The preferred entity awl of above-mentioned atomizing sprayer spiral nozzle, liquid pump just can form treatment fluid water smoke after by pipeline treatment fluid being delivered to these nozzle ejections, and treatment fluid can adopt water purification, but the desulfurized effect of water purification is not as limewash.
Position on the top of described wet scrubber 5 near its gas outlet is provided with water treatment plant 55, and the simplest water treatment plant is metallic plate or the plastic plate that intensive aperture is set.
The operation principle of described high-temperature flue gas comprehensive treatment equipment is:
The high-temperature smoke gas of discharging from the casting smelting furnace enters heat exchanger 2 through high-temperature flue gas passage 1, enters inertial dust separator 3 dedustings from the heat exchanger bottom then.The temperature of high-temperature flue gas reduces rapidly after the heat exchange, and this process approximately can be removed 50%～70% the particle diameter dust greater than 10um.
Then, flue gas enters in the wet scrubber 5 by connecting pipe 4.First atomizing sprayer 41 that is installed in this pipeline is preferably 120 ° of entity awl spiral nozzles, and the treatment fluid water smoke of nozzle ejection with the dust absorption of part 5～10um, has also absorbed part heat and the part sulfur dioxide in the flue gas simultaneously for the first time thus.
After flue gas enters wet scrubber 5, tubaeform outlet flue 42 places abrupt release in connecting pipe 4, because inertia rushes at the moisture film in the wet scrubber 5, adsorbed in a large number and collide after return again upwards and flow, at this moment, second atomizing sprayer 51 plays a role, to flue gas spray treatment fluid water smoke, because being the cylindrical design shower nozzle, the wet dust removal chamber adopts the design of all standing formula, so there is not any dead angle herein, improved the efficient of gathering dust and absorbing sulfur dioxide greatly, the dust of 5～10um of 80～90% and 60～80% sulfur dioxide are processed in this course falls.
The flue dust gas of handling continues to rise, treatment fluid water smoke by 52 ejections of the 3rd atomizing sprayer is further handled, whole flue dust air-flow is upset, form parallel airflow stably, filter by filter course 53 then, dust by 2～5um in the flue dust gas after this layer processing is thoroughly removed, and the sulfur dioxide more than 99% is absorbed.
The cleaning spraying device 54 that is used to spray water purification can in time spray cleaning to filter course 53, guarantees that filter course is not blocked, can work long-term effectively.When the flue gas of handling well passed through water treatment plant 55, part moisture wherein was filtered.Flue gas behind the drainage is introduced moisture separator 6 by blower fan, and moisture separator 6 is taken off and do not filtered clean water branch, qualified discharge then.
In addition, the air that is preheated in heat exchanger is sent into by Roots blower and is carried out combustion-supportingly in the body of heater, and good effect is played in the abundant burning of coke and molten iron temperature control, makes whole smelting process energy-conservation 8～10%.Certainly, consider, also can be applied to this part heat energy other the hot cell of using from energy-conservation angle.
