In technique scheme, horizontal tubular kettle comprises carbon steel sheet shell, is laid on the anti-corrosion leak-proof membrane layer of carbon steel sheet outer casing inner wall, and is laid on the liner heatproof anti-corrosion brick on membrane layer.
In technique scheme, the height placement form of partition wall has multiple, can, for contour, be preferably: along inlet, to liquid outlet direction, successively decrease step by step, liquid can overflow to last working chamber from first job chamber smoothly when facilitating filling liquid.
In technique scheme, in each chamber of horizontal tubular kettle, be provided with agitator, to impel reaction mass to mix, and make uniformity of temperature profile everywhere, be beneficial to the carrying out of reaction.Meanwhile, be also beneficial to and accelerate separating out of product sulfur dioxide.
In order to improve the flow regime of kettle inner fluid, the more important thing is and when turbulence state, can eliminate central authorities " cylindric tow-away zone ", make in having the stirring reaction process of suspension polymerisation, solid particle is thin and evenly, in each chamber, along the axial direction of horizontal tubular kettle, left and right wall vertical and that be close to chamber, is equipped with the barricade that anti-corrosion brick is made.Ore pulp is done circumference laminar motion along kettle periphery under the effect of agitator, repeatedly before barricade, is hampered and converts axial flow to, and ore pulp is fully mixed again, promotes the carrying out of reaction.
For reducing work noise, a kind of preferred technical scheme is: silencer is housed entering steam port.
The course of work of the horizontal acidifying extraction-container of the utility model is: ore pulp and sulfuric acid are successively injected the first working chamber from inlet and the acid inlet at extraction-container top, enter next working chamber, until last working chamber through partition wall overflow; Each working chamber passes into separately the steam of controlled rate, to ore pulp, provides reaction institute calorific requirement, and zinc sulfite is reacted with dilute sulfuric acid, and sulfur dioxide is parsed.Fully, after reaction, sulfur dioxide gas is discharged from last working chamber exhaust outlet, and liquid is discharged from last working chamber leakage fluid dram.
Remarkable result of the present utility model is:
1. horizontal acidifying extraction-container of the present utility model is separated into kettle the working chamber of a plurality of connections, and raw material constantly injects from first job chamber, through reaction of high order, from last working chamber, discharges.Whole process is a lasting process, middle be not interrupted, and has saved the time of the reinforced and discharging of staff, has improved production efficiency, and easy to operate, automaticity is high; And each working chamber has independently stirring system, through reaction of high order, make reaction more thorough, thereby improved resolution factor, the concentration of SO 2 gas of generation is stable.
2. compare the heating system of traditional employing coil pipe indirect, each working chamber is provided with independently steam-heating system, steam is directly passed into heated solution in still, the efficiency of heating surface is high, improved the utilization rate of steam, reduced the total consumption of steam, thereby reduced operating cost, and simple in structure, be convenient to safeguard.
