Description
Technical field
The environment friendly system of a kind of copper and smelting copper alloy belongs to the copper material manufacture field.
Background technology
In existing copper and copper alloy casting technology, general smelting furnace is the rotating turndown of tape spool, and melted alloy liquation is poured into tundish or holding furnace, so that further processing.Therefore, the flue dust cover above melting generally separates with smelting furnace, and bigger space is arranged between the two, operates to make things convenient for the workman, as adds alloy material, adds coverture, adds scouring agent, ladles out slag, topples over alloy liquation etc.Therefore, in actual production process, especially raw material contains the useless composition brass of part or when all be useless composition brass, because of in the composition brass that gives up with other a large amount of low-melting-point metals, inorganic non-metallic compound, organic matter etc., black smog fills the air whole workshop rapidly when feeding in raw material; In the copper alloy fusion process, low-melting-point metal is volatile, as volatilizes pungent zinc oxide steam fog, and after a period of time, knot is expired thick zinc oxide film etc. on the roof in workshop; In ladling out the slag process, with thermal current cigarette ash projection, melting work environmental abnormality is abominable in the whole workshop in the process of ladling out for the slag of high temperature, ash, and the environment outside the workshop is severe overweight also.Flue dust is contaminated environment not only, and the dust in the flue dust also can't reclaim, and lighter not going up again utilized.
According to incompletely statistics, process 400,000 tons of finished product copper and copper alloy with useless composition brass, dust in the flue dust and slag reach 10,000 tons, and the dust in 10,000 tons in the flue dust heavily accounts for nearly 30%.By analysis, on average contain zinc oxide 50wt% in dust in the flue dust and the slag, also contain aluminium, lead, copper etc.As the dust in the flue dust being reclaimed with favourable processing, utilization more from now on.Therefore, the environment friendly system of inventing a kind of copper and smelting copper alloy is copper and smelting copper alloy, particularly utilizes useless composition brass melting copper and copper alloy manufacturing technology problem anxious to be solved.
Summary of the invention
The objective of the invention is to overcome the shortcoming of existing copper and smelting copper alloy technology, a kind of environment friendly system of collecting the dust in slag, the flue dust in copper and the smelting copper alloy process is provided, provide a kind of copper and smelting copper alloy toxic emission to reach the system of national industrial gas emission standard, this system is the needs of green manufacturing, also has great economic worth.
Form to the doorstep by (3), flue dust cover (4), cyclone dust collectors (10), collection powder case (11), pipeline (5), pulsed jet cloth filter (6), disposal box (9), air-introduced machine (8), blast pipe (7), the slag passage (12) that falls, slag trapping box (13), operating desk (14) by smelting furnace (1), flue dust cover Xiamen (2), flue dust cover for the environment friendly system of a kind of copper of the present invention and smelting copper alloy.
In the environment friendly system of this copper and smelting copper alloy, smelting furnace (1) closely is connected with flue dust cover (4), and when system works, no industrial waste gas is overflowed from both junctions; Flue dust with the wind that enters flue dust cover Xiamen (2) with the wind that enters slag passage (12), successively enters flue dust cover (4), cyclone dust collectors (10), pipeline (5), pulsed jet cloth filter (6), blast pipe (7) under the effect of air-introduced machine (8); Cigarette and dirt in the flue dust are separated, the big high particle of particle, temperature is removed and is collected into by cyclone dust collectors in the collection powder case (11) in the flue dust, the low particle of particle, temperature thin in the flue dust is filtered, collects in the disposal box (9) by pulsed jet cloth filter (6), cigarette in the flue dust up to standard enters atmosphere from blast pipe (7), and the concentration of discharging dust is less than 28mg/m
3On operating desk (14), open flue dust cover Xiamen, to ladle out slag and pour slag passage (12) into, slag falls into slag trapping box (13) along passage, and flue dust can not overflowed from the slag passage (12) that falls; On operating desk (14), open flue dust cover Xiamen (2), carry out the operation of each operation of melting, cigarette can not overflowed from flue dust cover Xiamen (2), and is easy to operate; Shutting flue dust cover Xiamen (2) At All Other Times; Collection powder case (11), disposal box (9), the interior powder of slag trapping box (13), dirt, slag are in time cleared up respectively at normal temperatures, do not have flue dust during cleaning and overflow.
In the environment friendly system of above-mentioned a kind of copper and smelting copper alloy, flue dust cover Xiamen (2) and flue dust cover to the doorstep (3) are arranged on the flue dust cover (4), open flue dust cover Xiamen (2) and be convenient to smelting operation, open the flue dust cover to the doorstep (3) be convenient to smelting furnace (1) overhaul; At ordinary times, flue dust cover (3) to the doorstep generally is in closed condition.
The environment friendly system of a kind of copper of the present invention and smelting copper alloy is fit to the environmental protection treatment with the smelting furnace of useless composition brass manufactured copper of part and copper alloy.
The environment friendly system of a kind of copper of the present invention and smelting copper alloy is fit to the environmental protection treatment with the smelting furnace of whole useless composition brass manufactured coppers and copper alloy.
The environment friendly system of a kind of copper of the present invention and smelting copper alloy also is applicable to copper removal and copper alloy other the coloured and environmental protection treatment smelting ferrous metal stove in addition.
Compared with prior art, the present invention has following advantage:
Because existing smelting furnace is that Dumpage type, smelting furnace separate, have bigger space between the two with the flue dust cover, melting copper and copper alloy, particularly with the useless composition brass of part even when all giving up composition brass melting copper and copper alloy, pollute extremely serious, environment is extremely abominable, utility in the flue dust wastes, adopt the environment friendly system of a kind of copper of the present invention and smelting copper alloy, 1. the useful material in the flue dust is recovered, and reclaims back favourable this dust of developing a circular economy, reprocess; 2. the working environment of melting is improved greatly, and melting institute exhaust gas discharged is better than existing national industrial gas emission standard 100mg/m
