Abstract

The invention relates to a method to dry anode slime. The feature is that putting the anode slime into damp mass storehouse, feeding into vibrating screen through disk feeder, filtering the large particle and sending to built-in hop-pocket fluidized-bed passing through star-type feed valve and breaking up machine, blowing material by flow to make the particle suspending in flow to form fluidization, taking calorie exchange to dry anode slime. The invention has simple technology, rapid drying speed, and stable drying process. It solves the problem of discharging from plural outlets, and the smoke could be discharged directly.

Description

A kind of method of drying anode mud
Technical field
A kind of method of drying anode mud relates to the method for the material that dry high-thermosensitive is inhomogeneous, specific gravity difference is bigger, particularly dry nickel anode mud.
Background technology
Moisture content in the anode sludge behind the hydrometallurgy production electrolytic nickel reaches about 20%, during sulphur is produced at present, the anode sludge of airing that adds sulfur melting kettle is moisture about 12%, molten sulphur is actually the process of transpiring moisture in earlier stage, consumption of calorie accounts for 56% of molten sulphur total heat, the molten sulphur production efficiency of influence, and evaporate and contain sour water contaminated vapor environment, etching apparatus facility in a large number.In addition, be the sulfur product busy season winter, but freeze-up big with the material water capacity because of anode sludge stacking place, is forced to stop production, and causes great financial loss.
Summary of the invention
Purpose of the present invention is exactly the deficiency that exists at above-mentioned prior art, and a kind of heat energy consumption that can effectively reduce when being beneficial to nickel anode mud producer sulphur is provided, and reduces and pollutes, and guarantees the method for the drying anode mud that produce winter.
The objective of the invention is to be achieved through the following technical solutions.
A kind of method of drying anode mud, it is characterized in that the anode sludge hung by grab bucket and grab into the wet feed storehouse, be given to vibratory screening apparatus by disk feeder, vibratory screening apparatus sieves macrobead, screen underflow enters built-in cloth bag type fluidized-bed by sealing conveyor transfer roller through star-like feed valve, beater, and air-flow blows an interior material, makes material particles form fluidization among being suspended in air-flow, material under fluidized state, finish and air-flow between caloic exchange, the anode sludge is dried to water content less than 3%.
Method of the present invention is characterized in that its fluidized bed airflow inlet temperature is at 100-110 ℃.
Adopt method of the present invention, can effectively the anode sludge be carried out drying, reduced the energy expenditure of sulphur production process, reduced the production environment pollution.Technological process is simple, and rate of drying is fast, dry materials is even, the operating process good stability.Simultaneously, dry and dedusting is integrated in one, and saves investment, reduces floor space, has solved the difficult problem of many mouthfuls of dischargings, but the flue gas qualified discharge.
Embodiment
A kind of method of drying anode mud, the anode sludge hung by grab bucket grab into the wet feed storehouse, evenly be given to vibratory screening apparatus by disk feeder, vibratory screening apparatus sieves macrobead, screen underflow is by the star-like feed valve of sealing conveyor transfer roller process, beater enters built-in cloth bag type fluidized-bed, at induced draft fan, under gas blower and the interchanger acting in conjunction, air-flow evenly blows an interior material, make material particles form fluidization among being suspended in air-flow, material under fluidized state, finish and air-flow between caloic exchange, the control inlet temperature obtains water content weight less than 3% the anode sludge at 100-110 ℃.The anode sludge is transported to the siccative storehouse through star-like feed valve, chapelet, and tail gas is qualified discharge after the spray column washing.
Embodiment 1
Grab bucket is hung the anode sludge of weight in wet base 15% is grabbed into the wet feed storehouse, evenly is given to vibratory screening apparatus by disk feeder, and vibratory screening apparatus sieves macrobead, and screen underflow enters built-in cloth bag type fluidized-bed by sealing conveyor transfer roller through star-like feed valve, beater.Under induced draft fan, gas blower and interchanger acting in conjunction, the control inlet temperature is 100 ℃, finished drying process through 30 minutes, the anode sludge of dry back water content 3% is transported to the siccative storehouse through star-like feed valve, chapelet, and tail gas is qualified discharge after the spray column washing.
Embodiment 2
It is that 14% anode sludge is grabbed into the wet feed storehouse and evenly is given to vibratory screening apparatus by disk feeder that grab bucket is hung weight in wet base, and vibratory screening apparatus sieves macrobead, and screen underflow enters built-in cloth bag type fluidized-bed by sealing conveyor transfer roller through star-like feed valve, beater.Under induced draft fan, gas blower and interchanger acting in conjunction, the control inlet temperature is 105 ℃, just can finish drying process through 29 minutes, the anode sludge of dry back water content about 3% is transported to the siccative storehouse through star-like feed valve, chapelet, and tail gas is qualified discharge after the spray column washing.
Embodiment 3
It is that 16% the anode sludge is grabbed into the wet feed storehouse and evenly is given to vibratory screening apparatus by disk feeder that grab bucket is hung weight in wet base, and vibratory screening apparatus sieves macrobead, and screen underflow enters heavily built-in cloth bag type fluidized-bed by sealing conveyor transfer roller through star-like feed valve, beater.Under induced draft fan, gas blower and interchanger acting in conjunction, the control inlet temperature is 110 ℃, just can finish drying process through 27 minutes, the anode sludge of dry back water content 2% is transported to the siccative storehouse through star-like feed valve, chapelet, and tail gas is qualified discharge after the spray column washing.

Claims (2)
