Abstract
This invention discloses a method for producing compound (mixed) fertilizer pellets in pelletization column. The method comprises: sending liquid raw materials into a dissolution and buffer tank, adding normal temperature solid raw materials (K2SO4 or KCl), pumping into a mixing, dissolution and buffer tank at the top of the pelletization column, adding normal temperature solid raw materials phosphorus fertilizer, controlling the temperature, adding the raw materials into a pelletizer, and palletizing. The raw material temperature is controlled by adjusting the steam heating pipe in the dissolution and buffer tank, thus can achieve optimal pelletization effect. The open stages of the dissolution and buffer tank can be adjusted according to the liquid surface height, thus can control raw material melt viscosity as well as the pelletization effect. The product has high pelletization rate, good pellet quality, low steam loss, and low energy consumption.
Description
Technical field
Patent of the present invention relates to compound (mixing) fertile manufacturing technology, is specifically related to dissolving, insulation, mixing and the multistage conveying technology of material in a kind of compound (mixing) fertile high tower prilling production.
Background technology
At present, produce in compound (mixing) fertile high tower prilling production, in the material dissolution and dashpot that is adopted, set vapour pipe number is fixed, and temperature also is uncontrollable in the groove.And under the differing temps, material has different viscositys; All there is its optimum granulation viscosity in each composite fertilizer.Therefore, dissolving in the traditional method and dashpot, viscosity is unadjustable, causes product quality poor, and the range of product of a covering device production is very limited.
Summary of the invention
The objective of the invention is to, a kind of compound (mixing) fertile high tower graining method for producing is provided, this method can be according to the needs of material granulation, by optimum temperature of charge is provided, thereby guarantee the flowability of material, reach best granulation effect.
Technical scheme provided by the invention is as follows: construct a kind of compound (mixing) fertile high tower prilling method; comprise the steps: that a liquid material (liquid urea or liquid ammonium nitrate) is delivered to controllable type dissolving and dashpot; adding normal temperature solid materials vitriolate of tartar or Repone K mixes; ratio according to normal temperature solid materials and liquid material; by controllable type dissolving and dashpot; keep this suspension material temperature in certain limit; with controllable type mixed dissolution and the dashpot of pump delivery to the prilling tower tip position; add normal temperature solid materials phosphate fertilizer (monoammonium phosphate or diammonium phosphate); by controllable type mixing snubber assembly control temperature of charge; guarantee the prilling temperature that it is suitable, make this suspension material enter tablets press and carry out granulation.
In above-mentioned compound (mixing) fertile high tower prilling method, described dissolving and dashpot comprise the cell body of tubular, spacer sleeve is provided with many group controllable type steam pipeline sections on the outer side wall of described tubular cell body, be provided with the tortuous vapour pipe that constitutes in the bottom of groove, the export and import of vapour pipe passes the sidewall of tubular cell body, on the sidewall of tubular cell body bottom, be connected with the telescoping discharger that communicates with the groove inner chamber, top at groove is provided with electric motor, the output shaft of electric motor puts in the inner chamber of described dissolving and dashpot, is provided with agitating vane on axostylus axostyle.
The product balling ratio that this technology is produced is higher, and the particle quality is better, and range of product is more.Simultaneously, also reduce unnecessary vapor losses, saved the energy.This technology is a kind of more economical, more efficient, more energy-conservation technology.
Advantage of the present invention is: this method and device can be according to the variations of material, by regulating in material fusion and the snubber assembly the independently height of the upflow tube of steam heating coil and bottom of device, reach the purpose of control temperature of charge, finally reach best material granulation effect.In material dissolution and snubber assembly the design 3 to 5 sections separately independently, the vapour pipe that into has is arranged, can just regulate open hop count according to liquid level automatically.Bottom opening at groove connects a upflow tube simultaneously, can be flexible as TV set aerial.This upflow tube is by " U " type pipe principle, and the liquid level height is controlled the purpose that upflow tube reaches temperature in the control flume in the control flume, the viscosity of the molten slurry of control material, and then control the granulation effect.The product balling ratio that this technology is produced is higher, and the particle quality is better, and range of product is more.Simultaneously, also reduce unnecessary vapor losses, saved the energy.
Description of drawings
Below in conjunction with drawings and Examples patent of the present invention is further specified.
