Abstract
The invention discloses a device for high-efficiency and energy-saving separation, extraction and preparation of lead in lead-containing flue dust, which relates to the technical field of lead ore smelting. The device is characterized by comprising a stock bin, a rotary reactor, a vacuum belt-type filter, a circular treating system and an alkali liquor head tank, wherein the stock bin is connected with the rotary reactor through a screw conveyer; the rotary reactor is connected with the vacuum belt-type filter through a conveyer; the vacuum belt-type filter is connected with the circular treating system; and the circular treating system is connected with the alkali liquor head tank. According to the device disclosed by the invention, lead sulfate contained in the flue dust is converted into lead salt which can be used for more effectively reducing the smelting temperature and is easy to smelt according to the components in the flue dust; and combined equipment with high automatic flow and continuous production, such as the rotary reactor, the vacuum belt-type filter and the like are adopted, thus the aims of high efficiency and energy saving are achieved and the remarkable effect is achieved.
Description
Technical field
The present invention relates to the lead ore technical field of smelting, be specifically related to energy-efficient separation and Extraction preparation facilities plumbous in a kind of leaded flue dust.
Background technology
In lead ore smelting at present, the scrap lead reclaiming resource utilization smelting process,, leaded according to surveying and determination more than 40.6% through the flue dust that dust removal installation is collected; Mostly enterprise is together to put melting again in the smelting furnace into scrap lead or lead ore, and this method is not considered lead and the scrap lead in the flue dust, and the temperature of fusion of the lead in the lead ore is different; Not only waste heat energy, but also be easy to produce for the second time flue dust; Even dedusting technology do not reach when requiring, and can produce plumbous mist, lead dust, environment caused for the second time pollute.And not only lead tolerance is high in the flue dust, and the flue dust amount is also bigger.Like first field, circle, Fuyang city battalion recycling economy manufacturing district, will derive more than 30,000 ton of flue dust every year when producing 300000 tons of secondary leads per year, and the main plumbous smelting enterprise in the whole nation produces flue dust per year and will reach more than 200,000 ton.
Summary of the invention
Technical problem to be solved by this invention is to the weak point that exists in the prior art, provides a kind of to energy-efficient separation and Extraction preparation facilities plumbous in the leaded flue dust.
Technical problem to be solved by this invention adopts following technical scheme to realize,
The energy-efficient separation and Extraction preparation facilities of lead in a kind of leaded flue dust is characterized in that: comprise feed bin 、 rotation type reactor drum, vacuum belt filter, circulating treating system and alkali liquid high-level groove, described feed bin is connected Yu the rotation type reactor drum through worm conveyor; Described continuous rotating reactor is connected with vacuum belt filter through transfer roller; Described vacuum belt filter is connected with circulating treating system, and described circulating treating system is connected with alkali liquid high-level groove, and worm conveyor changes the flue dust send Ru rotation in the feed bin in the reactor drum; Automatically add desulfurization alkali lye from alkali liquid high-level groove; And keep the outlet pH value between 7-8, and be provided with vibratory screening apparatus in the continuous rotating reactor exit, remove bulk impurity; All the other waste materials get into vacuum band-type filter machine through transfer roller; Obtain to transform material and waste water, transform material can be used for smelting or doing further to extract lead salt after oven dry raw material, waste water gets into puts into alkali liquid high-level groove after the recycle treatment system is handled again.
Described desulfurization alkali lye is sodium hydroxide or yellow soda ash or sodium hydrogencarbonate.
Described feed bin is the sealing feed bin.
The invention has the beneficial effects as follows: the present invention is according to the composition of flue dust; The lead sulfate that wherein contains is changed into the lead salt that more can effectively reduce the easy melting of smelting temperature; Adopted automatic flows such as continuous rotating reactor and vacuum band-type filter machine high; The quantity-produced clustered aggregates has reached efficient, purpose of energy saving, and effect is obvious.
