Detailed description of the invention
In conjunction with Fig. 1 to Fig. 3, the utility model is described in more detail:
A kind of filtrating equipment of flue gas, comprises chamber 10, is provided with sponge filter pad 20 in chamber 10,On chamber 10, be connected with air inlet pipe 11 and escape pipe 12, described air inlet pipe 11 connects with cooling unitConnect, described escape pipe 12 is connected with air inducing unit.
Air inducing unit starting, the flue gas that the fire door of high-frequency melting furnace is produced is evacuated to this filterIn, being entered by air inlet pipe 11, the filter pad 20 that utilizes sponge material to make, utilizes sponge itselfPhysical characteristic, can adsorb fine particle and smoke in flue gas, can strengthen the filtration to flue gasEffect, the flue-gas temperature producing due to high-frequency melting furnace fire door is higher, and sponge filter pad 20 filtersEffective, utilize the cooling unit being connected with air inlet pipe 11, can will enter the flue gas of filterCooling, avoid high-temperature flue gas burning to sponge filter pad.
As preferred version of the present utility model, for further increasing filter area and air permeable effect,Described air inlet pipe 11 postpones with the direction of escape pipe 12 and is vertical with the pad face of sponge filter pad 20,The tube chamber cross section of air inlet pipe 11 and escape pipe 12 is less than the pad face of sponge filter pad 20. In conjunction with Fig. 1And Fig. 2, above-mentioned air inlet pipe 11 and the tube chamber cross section of escape pipe 12 are less than sponge filter pad 20Pad face, makes filter entirety present that chamber 10 is large, two ends are little into and out of tracheae 11,12Logical tubular structure, can be at the interior multilayer sponge filter pad 20 that arranges of chamber 10, multilayer sponge filter pad20 levels and interval arrange, thereby in increasing smoke filtration area, have increased ventilativeEffect.
The thickness of described sponge filter pad 20 is 5～20mm, and sponge filter pad 20 is along chamber 10Interior above-below direction horizontal interval is provided with multilayer, and the material of sponge filter pad 20 can be selected resistance to heightThe sponge material of temperature is made.
Preferably, for guaranteeing the bonding strength of air inlet pipe 11 and escape pipe 12 and chamber 10, instituteBetween the two ends of stating chamber 10 and air inlet pipe 11 and escape pipe 12, be connected by Taper Pipe transition respectively.
For implement to extract flue gas lower the temperature fast, described air inlet pipe 11 by pipeline withBleed unit connect, described cooling unit comprises the mist pipe being arranged in pipeline, described mist pipeStretch in the tube chamber of pipeline, mist pipe is provided with atomization water nozzle on along its length. Above-mentioned mistChange pipe in the process of spraying, not only can play cooling effect fast, and can also be by flue gasIn tiny dust granule settle down, reach the effect of preliminary cleaning flue gases, reduce filter dressPut the intensity filter of interior sponge filter pad 20.
Described sponge filter pad 20 is arranged on the carriage 21 in chamber 10, carriage 21Upper and lower frames face position is respectively arranged with supporting network 22, and carriage 22 forms level side with chamber 10To drawing and pulling type coordinate;
In described chamber 10, be provided with guide rail 13, described guide rail 13 is positioned at the two relative of chamber 10On sidewall, arrange, described guide rail 13 is the gusset of a length direction level, and carriage 21 arrangesBoth sides are arranged on guide rail 13, and carriage 21 is joined with the drawing and pulling type that guide rail 13 forms horizontal directionClose;
Above-mentioned carriage 21 coordinates with the drawing and pulling type that guide rail 13 forms, can be conveniently by sponge filter padOut, and the behaviour in service of observing sponge filter pad 20, when sponge filter pad 20 is put aside for 20 pullsDust more and while causing filter effect to reduce, can be by the comparatively clean sponge filter pad of other layers20 change to this layer, so just can reduce the use amount of sponge filter pad 20, further reduce realThe filtration cost on border, and the replacing of above-mentioned structure is convenient, simple to operate.
For strengthening further filter effect, close in the chamber 10 of escape pipe 12 and be also provided with sprayShower pipe 30, described shower 30 along the inner peripheral wall of chamber 10 around, the pipe of shower 30The spaced apart water spout that is provided with it, the water spout sensing interior the superiors of chamber 10 sponge filter pad 20Pad face. Utilize water spout to implement the water spray operation to sponge filter pad 20, sponge filter pad 20 is inhaledAfter water, can strengthen the filter effect to flue gas, the weight of sponge filter pad 20 own is also increasing,For avoiding the generation of heavier 20 dozens of pocket phenomenons of sponge filter pad, can be at the upper and lower frames of carriage 21Face position is respectively arranged with supporting network 22, and this supporting network 22 can be implemented sponge filter pad 20Effectively support.
The above-mentioned spray operation that whether starts shower 30, can detect cooling unit cigarette afterwardsTemperature degree and determining, when flue-gas temperature is lower can't burn sponge filter pad 20 time, canStarting shower 30 sprays.
Above-mentioned air inducing unit 40 is for being arranged on the air-introduced machine on chamber 10 escape pipes 12, air inducingMachine comprises blade 41, and blade 41 is positioned at escape pipe 12, the output of blade 41 and drive motorsAxle connects, and then makes blade 41 rotations produce guiding air-flow upwards, and the below of chamber 10 is enteredOn tracheae 11, can offer the discharging opening that Open Side Down, the corresponding groove 50 that connects material that arranges in below of discharging opening,The groove 50 that connects material can be accepted the sewage that air inlet pipe 11 falls down.
