Vibration fluidized bed of nickel sulfate production line
Kam material is sulfuric acid, strongly acidic and corrosive, Division I for this feature on the manufacturing equipment upgrades and improvements, vibration fluidized bed upper box and lower box and the inner walls are made of glass fiber reinforced plastic 3mm full attachment, nickel plate vibration plate using a special punch holes Benn production, emissions used in all high-temperature corrosion-resistant glass fiber reinforced plastic material. Bracket and support tube is also special carbon steel Teflon material. In order to achieve good results in emissions, bag filter bag select a special material, extremely acid, even Cited fan frequency tiaofeng also used FRP production. This process is a good solution to the high-temperature materials drying process encountered high corrosion problems.
Anhydrous nickel sulfate, six water and seven water was three. For more goods six water with α- and β- type type two variants, the former crystalline blue square, which is a green monoclinic crystal. Lost heated to 103 ° C when six crystal water. Soluble in water, slightly soluble in ethanol, methanol, acidic aqueous solution, slightly soluble in acid, ammonia, and toxic. Mainly used in electroplating industry, pharmaceutical industry, mineral industry, dyeing industry.
Material from the feed inlet into the machine, under the effect of the vibration motor excitation force or otherwise made available in the air distribution plate jump forward, and after the air was filtered, heated to a certain temperature, the air into the dryer at the plenum the material in the dual role of vibration force hot air through the air distribution plate and all of the wind, was carried out between the suspension and the hot air in contact with the heat medium material particles intense turbulence, heat transfer and mass transfer process can be strengthening the dried product is discharged from the discharge port, evaporated water and exhaust gas recovered by the cyclone dust into the atmosphere. Bed body to the bed provides a stable with a certain pressure plenum. Adjusting fan, so that the upper portion of the box in the bed material to maintain slightly negative pressure, to maintain a good dry environment and prevent dust leakage.
Nickel sulfate Features:
1. The material is heated evenly and heat exchange is fully dry and high intensity, energy-efficient than conventional dryer about 30%. Vibration source is driven by vibration motor, smooth operation, easy maintenance, low noise and long life. Stable fluidization, no dead ends and broken phenomenon. Little damage to the surface of the material can be used for brittle dry material particles does not affect the effect of irregular work.
2. The use of fully enclosed structure, effectively prevent cross-contamination between the air and the material, the working environment clean. Adjustable resistance, wide adaptation, material thickness and moved inside the machine speed and amplitude can be adjusted steplessly.
3. Since vibrations are applied, can reduce the minimum fluidizing gas velocity, which can significantly reduce the demand for air, thereby reducing the entrained dust layer, matching heat, fans, cyclones and other specifications can also be reduced accordingly, reducing equipment, energy-saving effect obvious. Can easily adjust the vibration to rely on parameters to change residence time in the dryer. Its plug flow operation reduces the particle size uniformity of the material and regulatory requirements, easy to obtain a homogeneous dry product.
