The purpose of energy-saving and emission-reduction.
Detailed description of the invention
The utility model is described in further detail in the following with reference to the drawings and specific embodiments.
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the structural schematic diagram of dust storage groove frame；
Drawing reference numeral: 1, exhaust pipe, 2, subsider, 3, spiral board, 4, dust storage groove frame, 5, suction ventilator, 6, ventilation duct,
7, cylinder, 8, spray waterpipe, 9, heavy dirt pond are sprayed.
Specific embodiment
A kind of specific embodiment of the utility model, cupola furnace dust-extraction unit are proposed as shown in Figure 1, including are connect with cupola furnace
Exhaust pipe 1, the end of the exhaust pipe 1 connect with a curvilinear subsider 2, the subsider 2 it is outer
Surrounding is equipped with a dust storage groove frame 4, and the dust storage groove frame 4 removably coats subsider 2, and the end of the subsider 2 passes through pipe
Road connects a suction ventilator 5, then suction ventilator 5 can be by the tail gas inspiration subsider 2 in exhaust pipe 1, and the present embodiment is on ground
Curvilinear subsider 2 is arranged in face, and with cement concrete mortar the inner wall of subsider 2 is made flat and smooth, works as tail gas
By subsider 2 turning when, the inner wall at tail gas and turning rubs, due to friction generate resistance cause ash fall
With the bottom of subsider 2, the suction ventilator 5 is connect by ventilation duct 6 with a spray cylinder 7, and the spray cylinder 7 is in cylinder
Shape, the present embodiment setting spray cylinder 7 be to be welded by thickening steel plate, spray cylinder 7 basal diameter be 100 centimetres,
A height of 500 centimetres, the end of the ventilation duct 6 is set at the bottom end section of spray cylinder 7, and the end of the ventilation duct 6 is set
Spiral air inlet is set, then tail gas enters after spray cylinder 7 from spiral air inlet forms spiral wind, sets in the spray cylinder 7
There is spray waterpipe 8 of the extension outside it, the spray waterpipe 8 connects water system, this implementations, which is arranged spray waterpipe 8 and is located at, to be sprayed
At 7 axial centre of cylinder, it is uniformly provided with screw spraying hole on the spray waterpipe 8, then shape after water is sprayed from screw spraying hole
At spiral water mist, and the contrary setting in the direction of the spiral air inlet and the screw spraying hole, then it sprays in cylinder 7
Spiral wind and spiral water mist steering on the contrary, even spiral wind be clock wise spirals when, water mist is counter-clockwise helical, realize ash
The bottom end of dirt and water mist close adhesion, the spray cylinder 7 connects a heavy dirt pond 9 by a pipeline, then the ash settled by water mist
Dirt sinks in dirt pond 9 as shower water is entered by pipeline.
The top of the spray cylinder 7 is equipped with a spiral board 3, then the setting of spiral board 3 in flabellum form and is set to spray
It drenches at the center on 7 top of cylinder, when water mist passes through, the spiral board 3 of rotation gives one resistance of water mist, and then water mist is made to fall to spray
It drenches in cylinder 7, so that the water mist for effectively reducing spray cylinder 7 causes chimney to block as the tail gas after dedusting enters chimney, from
And influence that cupola furnace burning is bad or even dead fire, guarantee the normal work in cupola furnace.
What the dust storage groove frame 4 was made from a material that be thermally conductive, the present embodiment setting is selected as iron plate material, and the present embodiment will store up
Dirt slot frame 4 is set in baking chamber, and the dust storage groove frame 4 is set as down narrow wide trapezoidal shape, and the top of the dust storage groove frame 4
It is detachably equipped with netted iron plate, as shown in Fig. 2, the heat convenient for tail gas comes out using mould drying, is efficiently used in tail gas
Heat improves the utilization rate of heat, realizes the purpose of energy-saving and emission-reduction.
When the utility model is used: spray waterpipe 8 connects water system, and suction ventilator 5 connects power supply, starts dust-extraction unit,
Exhaust pipe 1 collects the tail gas in cupola furnace, and under the action of suction ventilator 5, tail gas is introduced into subsider 2, when tail gas passes through
When the turning of subsider 2, the inner wall at tail gas and turning rubs, and causes ash fall since friction generates resistance and sinks
The bottom of slot 2 drops, and at this moment large dust particle has settled in tail gas, and the heat in tail gas, which is distributed by dust storage groove frame 4 to mould drying, to be made
With；Little particle dust sprays in cylinder 1 as tail gas is entered by spiral air inlet, forms spiral wind, and spray waterpipe 8 passes through spiral shell
Rotation water hole, which sprays spiral water mist, glues little particle dust closely with spiral water mist since spiral wind is contrary with spiral water mist
Even, and then along water flow enter in heavy dirt pond 9, at this moment almost removal is clean for the dust in tail gas, and the water mist with tail gas is revolving
Under the blocking of flowing plate 3, backflows to spraying in cylinder 7 and then entering in heavy dirt pond 9, prevent chimney from blocking.
Certainly, only the utility model preferred embodiment is described in detail in conjunction with attached drawing above, not
The scope of the utility model is limited with this, it is all according to equivalence changes made by the principles of the present invention, construction and structure,
It should all be covered by the protection scope of the utility model.
