Abstract
An energy-saving wind-cooling and water-cooling combination dust collector for a cupola furnace is characterized in that the waste gas after a cooling by a heat-air internal furnace heat exchanger (1) comprising an inner core (3) and a plurality of ribs (4) welded on the outer wall of the dust collector and an outer welding rib cover (5) and an air adjuster is further cooled through a heat radiation pipeline (16) and under the function of a water spraying pipe (15), and then is sent into an atomizer chamber formed by an outer shell (22) and is dedusted and cooled by a water spraying nozzle (23); the dedusted water gas then is exhausted by a terminal exhaust fan (27) and sent to the atmosphere. The utility model has the advantages of good dedusting and energy conservation effects, low cost, long service life and convenient maintenance, etc, thus being applicable in cupola furnace producing enterprises.
Description
The utility model belongs to the equipment of industrial product, relates in particular to a kind of energy-saving air-cooled, water-cooled combined duster that is applied to furnace cupola.
China's furnace cupola of existing Foundry Production at present is divided into cold wind, blast-heating cupola.The furnace gas temperature that cold blast cupola is overflowed reaches 400～800 ℃, and in the furnace gas, CO content weighs about 10%; Blast-heating cupola is divided into two kinds, and charge door is the internal heat type blast-heating cupola to have the flue heat exchanger, and being provided with the flue heat exchanger more than the charge door is top formula blast-heating cupola.China is at the furnace cupola waste gas emission standard, and the discharging of strict control CO content is because it includes a large amount of sulfur oxides; Special control dust discharge amount is at 150～200 milligrams/meter
3In.At present dedusting technology is two kinds, a kind ofly establishes suction opeing at the charge door place, and dust, furnace gas are evacuated in the cyclone dust collectors, and its effect is not good enough, is difficult to up to standard; Another kind is multistage bag-type dust removal system, because the furnace gas temperature height, cloth bag is baking for a long time between 200～400 ℃, causes expanding, and stops up, and has the high problem of fault rate.
The purpose of this utility model just provides a kind of deduster of using in the furnace cupola production process air-cooled, water pouring atomizing compound mode that utilizes.The main technical schemes that the utility model is dealt with problems is: deduster is by support, blower fan, the hot-blast stove chamber heat exchanger, air regulator, water drenches compositions such as atomizer, described hot-blast stove chamber heat exchanger is by being welded with some muscle sheets on inner bag and its outer wall and outside weld muscle sheet cover is formed, inner bag is connected with the furnace cupola waste gas outlet by warm-air pipe, and below shell, be provided with air inlet, the top then is provided with air outlet and is connected with the flue of furnace cupola by ajutage, the flue upper end is welded with sealing flange, the lower end is through flange and air regulator Bolt Connection, this air regulator is made up of mixed air vessel and funnel that shell forms, one side of mixed air vessel is provided with the air inlet of band air conditioning valve, and the outlet that crude particle dust is got rid of in the funnel lower end is provided with valve; Described water drenches atomizer then to be made up of water pouring spray chamber, funnel and water hose nozzle etc. that shell forms, the waste gas that the upper end of spray chamber will be provided with after air outlet will be purified by the terminal air exhauster by pipeline is taken away, and be provided with safety valve in the top, the lower end then is provided with gap, and the exit of funnel is provided with valve; Blender and atomizer then drench device by a water and connect, this water drench device hot channel two ends respectively with the blender upper side wall on air outlet be connected with air inlet on the atomizer sidewall, be provided with water and drench pipe above hot channel, its below then is provided with water storage tray and bottom gap.The utility model is air-cooled owing to taking, water drenches tube wall, water drenches atomizing combined type dust suppression, thereby for furnace cupola manufacturing enterprise provides a kind of dedusting, good energy-conserving effect, cost is low, and the life-span is long, cleaner easy to maintenance.
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 for the utility model cooling, cleaner in conjunction with schematic diagram.
When implementing the utility model, air regulator 14 and water drench atomizer 20 and are fixed on the ground in workshop by support 12, the furnace cupola waste gas outlet is connected by the air inlet 2 that pipeline and upper end are welded with the hot-blast stove chamber heat exchanger 1 of sealing flange 6, waste gas about 600 ℃ is delivered to inner bag 3, utilize hair-dryer from the interior empty air-supply of cold wind import 7 reflux types in heat exchanger bottom between inner bag 3 and outer cover 5, reduce high temperature in the courage is useless by the radiation rib on the inner bladder outer wall 4, simultaneously can obtain 200～300 ℃ of hot blasts preferably, infeed soaring flue from air outlet 8 once more by pipeline, thereby improve the furnace cupola wind pushing temperature, energy savings.And by heat exchanger 1 cooled waste gas enter make the mixed air vessel of shell 9 by steel plate after, make it and mix from 40～60% the cold air that is provided with that air conditioning valve 10 air inlet places enter, as by the hot blast behind the flue heat exchanger 200～300 ℃ with after cold air cooperates, can reduce between 100～150 ℃.Crude particle dust in the cooling procedure then is deposited among the funnel 11, can regularly open valve 13 and discharge.Gaseous mixture then passes through from the hot channel 16 of water pouring device 19, the below that this water drenches device 19 is provided with water storage tray 17, its bottom is provided with gap 18, drench at water under the effect of pipe 15, making gaseous mixture by hot channel 16 further be cooled to 100 ℃ enters in the spray chamber with interior, these atomizer 20 shells 22 and steel plate weldering are pressed, the top is provided with safety valve 24, open the spray chamber upper water and drench nozzle 23, make an amount of water smoke and 100 ℃ the atomizing depositing dust take place, produce moisture content with interior waste gas, backflow is in the bottom, and mud dirt concentrates among the funnel 21, can regularly open valve 13 and discharge, waste water overflows in gap 25.Waste gas after the dedusting can be reduced to about 50 ℃, is connected with terminal air exhauster 27 by airduct 26 by top exit.The air outlet of terminal air exhauster can be installed water-tight type cistern or simple and easy sack cleaner, through ground pit type or tower pipe outlet, harmless Purge gas is disappeared among the Nature.
