Detailed description of the invention
Composition graphs 1 to Fig. 8, is described in more detail the present invention:
A kind of flue gas processing device, the fire door place of mid-frequency melting furnace arranges gas skirt 10, and the outlet side of gas skirt 10 connects smoke filtration unit 30 and air inducing unit 40 successively by pipeline, arranges cooling unit between gas skirt 10 and smoke filtration unit 30.
Shown in composition graphs 1, utilize the gas skirt 10 being arranged on mid-frequency melting furnace A fire door position, air inducing unit 40 starts, fast and effeciently can eliminate the flue gas that mid-frequency melting furnace A fire door place produces, utilize the cooling unit be arranged between gas skirt 10 and filter element 30, the temperature of flue gas can be reduced, utilize the filtration that filter element 30 can effectively be implemented flue gas, and will the air venting of flue gas do not contained in air, this flue gas processing device fast and effeciently can eliminate the flue gas that mid-frequency melting furnace A fire door produces, the work condition environment in operation workshop can be significantly improved, reduce the labour intensity of operator.
As preferred version of the present invention, the side of described gas skirt 10 is connected with support 50, one end away from gas skirt 10 on support 50 forms slippage with guide part 60 and coordinates, and the cover body cantilever type of gas skirt 10 moves to the fire door of mid-frequency melting furnace A or the fire door position away from mid-frequency melting furnace A.Mid-frequency melting furnace A is after melting completes, body of heater overturns, solution stream is from guiding gutter, the fire door of the mid-frequency melting furnace A of gas skirt 10 after upset now is now made by artificial or mechanical mode, and then the flue gas that mid-frequency melting furnace A fire door place can be produced is eliminated clean, this kind of gas skirt 10 slidingtype is arranged on guide part 60, and with the fire door of mid-frequency melting furnace A present near or away from two states, under the state do not used, make gas skirt 10 away from the fire door of mid-frequency melting furnace A, also can avoid the interference of gas skirt 10 pairs of mid-frequency melting furnace A flip-flop movements.
As preferred version of the present invention, the flue-gas temperature produced due to mid-frequency melting furnace A fire door is higher, but also being mingled with a certain amount of dust granule, described cooling unit comprises the atomizing unit 70 in the pipeline that is arranged at and connects between gas skirt 10 and smoke filtration unit 30.The water smoke that this atomizing unit 70 produces, while reduction temperature, also can settle down the dust granule be mingled with in flue gas.
Further, described smoke filtration unit 30 comprises the chamber 32 arranging sponge filter pad 31, chamber 32 connects air inlet pipe 33 and escape pipe 34, air inlet pipe 33 unanimously carries over the direction of escape pipe 34 and vertical with the pad face of sponge filter pad 31, and the tube chamber cross section of air inlet pipe 33 and escape pipe 34 is less than the pad face of sponge filter pad 31.This filter element 30 is entered by the flue gas after lowering the temperature, flue gas enters along air inlet pipe 33, and by sponge filter pad 31, sponge filter pad 31 can adsorb flue gas particle impurity and smell effectively, comparatively clean air after filtration is discharged by escape pipe 34, shown in composition graphs 7, above-mentioned air inlet pipe 33 and the tube chamber cross section of escape pipe 34 are less than the pad face of sponge filter pad 31, filter element 30 is made to present chamber 32 large, two ends turnover tracheae 33, 34 little tubular structures, can multilayer sponge filter pad 31 be set in chamber 32, the pad face of this sponge filter pad 31 is parallel to each other, the filter area to flue gas can be increased further, increase air permeable effect, and then the filter effect guaranteeing flue gas.
For guaranteeing the bonding strength of air inlet pipe 33 and escape pipe 34 and chamber 32, the two ends of described chamber 32 are connected by Taper Pipe transition respectively with between air inlet pipe 33 and escape pipe 34.
In enforcement in the process of smoke filtration, be positioned at the flue gas that undermost sponge filter pad 31 filters at first, therefore, this layer of sponge filter pad 31 adsorbs a large amount of soot dust granules at first, until the effect playing filtration cannot be continued, therefore for convenience of inspection and the replacing of sponge filter pad 31, shown in composition graphs 8, described sponge filter pad 31 is arranged on the carriage 321 in chamber 32, the position, upper and lower frames face of carriage 321 is respectively arranged with supporting network 322, and the drawing and pulling type that carriage 321 is formed in the horizontal direction with chamber 32 coordinates.Chamber 32 is wherein provided with on the slotted-angle shelving 323 coordinated with the both sides of carriage 321, carriage 321 forms drawing and pulling type with slotted-angle shelving 323 and coordinates, like this can conveniently by sponge filter pad 31 pull out, and observe the behaviour in service of sponge filter pad 31, when sponge filter pad 31 is accumulated more impurity and is caused filter effect lower, sponge filter pad 31 comparatively clean for other layers can be changed to this layer, the use amount of sponge filter pad 31 can be reduced like this, reduce actual filtration cost further.
For increasing the filter effect to flue gas further, shower 35 is also provided with in the chamber 32 closing on escape pipe 34, described shower 35 along chamber 32 inner peripheral wall around, spaced apartly on the pipe shaft of shower 35 be provided with water spout, water spout points to the pad face of the superiors' sponge filter pad 31 in chamber 32.Utilize the spray operation of water spout enforcement to sponge filter pad 31, after sponge filter pad 31 absorbs water, the filter effect to flue gas can be strengthened, the weight of sponge filter pad 31 itself is also in increase, for avoiding the generation of heavier sponge filter pad 31 dozens of pocket phenomenons, can be respectively arranged with supporting network 322 in the position, upper and lower frames face of carriage 321, this supporting network 322 can implement the effective support to sponge filter pad 31.
