Detailed Description
In order to clearly understand the technical features, objects, and effects of the present invention, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
The casting process of aluminum generally comprises the steps of burdening and charging, heating and heating for melting, slagging and stirring, secondary feeding, slagging and stirring, quenching and tempering for refining, slagging, standing and casting. The amount and concentration of the exhaust gas produced in each stage are different. Based on this, as shown in fig. 1, the utility model provides an aluminum furnace is melted to environment-friendly, including being used for the furnace body 100 of aluminium founding, with the corresponding setting of furnace body 100 is used for collecting the gas collection device 200 of furnace body waste gas, gas collection device 200 links to each other with dust collector 300, spray column 400 through the pipeline in proper order, so that waste gas discharges after removing dust, the desulfurization, wherein dust collector 300 includes large granule dust collector 310, micronic dust processing apparatus 320 and select switch 330 at least, select switch 330 is used for control waste gas gets into large granule dust collector 310 or micronic dust processing apparatus 320. Now, for example, in the working process, the selection switch 330 is uniformly controlled by a human or an aluminum melting furnace main control device to ensure the accuracy of the judgment, when the steps of slag skimming and stirring, secondary feeding, slag skimming and stirring, quenching and tempering, refining and slag skimming are performed, the concentration of the generated waste gas is high and a large amount of particle impurities exist, so that preliminary treatment needs to be performed first, and therefore the selection switch 330 conducts the waste gas to the large particle dust removal device 310; during the standing and casting processes, the generated exhaust gas is less, and the concentration is lower, so the selection switch 330 can directly conduct the corresponding exhaust gas to the fine dust processing device 320.
In this embodiment, the large particle dust removing device 310 employs a cyclone, the inlet of the cyclone is connected to the selection switch 330, and the gas outlet of the cyclone is connected to the fine dust processing device 320. The device for treating the fine dust comprises a pretreatment chamber 321 and a bag-type dust collector 322, wherein an inlet of the pretreatment chamber 321 is respectively connected with the selective switch 330 and an air outlet of the cyclone dust collector, an outlet of the pretreatment chamber 321 is connected with an inlet of the bag-type dust collector 322, and an air outlet of the bag-type dust collector 322 is the outlet of the dust collector 300. It is understood that the inlet of the pretreatment chamber 321 may be one or more, and the selection switch 330 and the gas outlet of the cyclone may be combined into a pipe and then connected to the pretreatment chamber 321, which is not limited herein, wherein the pretreatment chamber 321 performs pretreatment such as buffer cooling, deflagration, etc. on the exhaust gas. The bag-type dust collector 322 can be an air tank pulse bag-type dust collector or a low-pressure line-spraying bag-type dust collector, and in this embodiment, a low-pressure line-spraying bag-type dust collector is selected. In this embodiment, a temperature sensor may also be provided in the pre-chamber 321 to monitor the system operating conditions.
Because the fuel adopted by the aluminum melting furnace may be a sulfur-containing material, if the waste gas after dust removal is directly discharged to seriously pollute the environment, the waste gas after dust removal needs to be desulfurized, specifically, the spray tower 400 comprises an air blower 410 and a tower body 420, the air blower 410 is connected with the outlet 300 of the dust removal device and is used for blowing the waste gas after being treated by the dust removal device 300 into the tower body 420, as can be understood, the step can further improve the dust removal effect while desulfurizing, specifically, the tower body is a multi-stage rotational flow plate spray absorption tower, the waste gas after dust removal enters the bottom of the multi-stage rotational flow plate spray absorption tower under the driving of the air blower 410, is washed by water bath, pollutants in the waste gas are combined with impact water mist and circulating spray water to form waste water, the waste water is separated by centrifugation or filtration, and flows into a circulating pool due to gravity, and purified gas passes through the top, the waste water is periodically cleaned and fished and transported outside in the circulating tank. The waste gas generated in the casting process of the aluminum is treated to meet the national standard. It can be understood that the multistage cyclone plate spray absorption tower can improve the purification effect by replacing water with other solvents, such as gypsum desulfurization and the like, and is not limited herein.
