Abstract
The utility model relates to a chemical fertilizer production facility, an urea aldehyde slowly -releasing fertilizer apparatus for producing specifically says so. Including crystallization chamber, the evaporating chamber of setting on crystallization chamber, the upper end of evaporating chamber is equipped with the gas vent, and the lower extreme of evaporating chamber is equipped with central that extends to in the crystallization chamber inner chamber, crystallization chamber's upper end is equipped with the back flow, and crystallization chamber's lower extreme is equipped with the discharging pipe, is provided with the inlet tube on the evaporating chamber, and it has the heat exchanger to establish ties between inlet tube and the back flow, and crystallization chamber's bottom is fixed and is provided with the cone, and the lower extreme of a center section of thick bamboo has the horn mouth, and the top of cone is arranged in the horn mouth. Material that the cone can flow the center tube is to dispersion all around, is favorable to the formation of crystalline solid and improves the mobility of crystalline solid, is convenient for form even crystallization granule and easily realizes continuous production, the condenser pipe can flow back most hot steam condensate to in the evaporating chamber, is favorable to the energy saving, improves production efficiency.
Description
Technical field
The utility model relates to a kind of fertilizer production equipment, is a kind of urea aldehyde slow release fertilizer process units specifically.
Background technology
During urea aldehyde slow release fertilizer is produced, the oslo crystallizer that the MAP as intermediate products mostly adopts chemical industry conventional obtains, and its structure is simple, easy to operate, can realize working continuously.Oslo crystallizer utilizes a central tube to be communicated with crystallisation chamber setting up and down and vaporization chamber, along with the diameter of production-scale expansion, crystallisation chamber, vaporization chamber and central tube is all larger, when central tube diameter is larger time, material is fallen into after bottom crystallisation chamber by central tube, cannot spread to surrounding, material is too concentrated, be unfavorable for the formation of crystalline solid, or the crystalline solid formed is deposited in central tube mouth of pipe place, can not flow, crystalline particle is uneven, and what impact was produced carries out smoothly; In addition, high-temperature steams a large amount of in production process takes away partial heat and raw materials for production, causes the pollution of energy waste and environment.
Summary of the invention
The purpose of this utility model be to provide a kind of crystalline solid good fluidity, crystalline particle evenly, economize energy, be convenient to quantity-produced industrial grade monoammonium phosphate production crystallizer.
For achieving the above object, the utility model is by the following technical solutions:
A kind of urea aldehyde slow release fertilizer process units described in the utility model comprises crystallisation chamber, be arranged on the vaporization chamber of crystallisation chamber upper end, the upper end of described vaporization chamber is provided with exhaust outlet, the lower end of vaporization chamber is provided with the central tube extended in crystallisation chamber inner chamber, the upper end of described crystallisation chamber is provided with return duct, the lower end of crystallisation chamber is provided with discharge nozzle, described vaporization chamber is provided with inlet tube, described return duct connects inlet tube by liquid pump, center bottom described crystallisation chamber is fixedly installed cone shape cone, the lower end of described central tube is with horn mouth, the top of described cone is arranged in horn mouth, with gap between bell-mouthed inwall and cone, with condenser pipe in the inner chamber of vaporization chamber, between inlet tube and exhaust outlet, communicating pipe is provided with between crystallisation chamber and vaporization chamber, the junction of described communicating pipe and crystallisation chamber is higher than return duct, and the junction of described communicating pipe and vaporization chamber is between inlet tube and condenser pipe.
Adopt after technique scheme, the material that central tube flows out can disperse to surrounding by cone, is conducive to the formation of crystalline solid and improves the mobility of crystalline solid, be convenient to form uniform crystalline particle and be easy to realize continuous seepage; Condenser pipe by most of vapours condensing reflux in vaporization chamber, can be conducive to economize energy, enhances productivity.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model will be further described.
As shown in Figure 1, a kind of industrial grade monoammonium phosphate production crystallizer described in the utility model comprises crystallisation chamber 1, be arranged on the vaporization chamber 2 of crystallisation chamber 1 upper end, the upper end of described vaporization chamber 2 is provided with exhaust outlet 3, the lower end of vaporization chamber 2 is provided with the central tube 4 extended in crystallisation chamber 1 inner chamber, the upper end of described crystallisation chamber 1 is provided with return duct 5, the lower end of crystallisation chamber 1 is provided with discharge nozzle 6, described vaporization chamber 2 is provided with inlet tube 7, described return duct 5 connects inlet tube 7 by liquid pump, also heat exchanger 8 can be in series with between described inlet tube 7 and return duct 5, the bottom centre position of described crystallisation chamber 1 is fixedly installed cone shape cone 8, this cone 8 can be solid centrum, also can be hollow centrum.The lower end of described central tube 4 is with horn mouth 9, and the top of cone 8 is arranged in horn mouth 9, with gap between the inwall of horn mouth 9 and cone 8, so that material glides along cone 8.
With condenser pipe 10 in the inner chamber of vaporization chamber 2, between inlet tube 7 and exhaust outlet 3, communicating pipe 11 is provided with between crystallisation chamber 1 and vaporization chamber 2, the junction of described communicating pipe 11 and crystallisation chamber 1 is higher than return duct 5, and the junction of described communicating pipe 11 and vaporization chamber 2 is between inlet tube 7 and condenser pipe 10.The two ends of condenser pipe are connected with condensed water circulation device respectively.Pass into condensed water in condenser pipe 10 and realize cooling.Run in vapours uphill process in vaporization chamber 2 under condenser pipe 10 cooling becomes liquid and fall back in vaporization chamber.
By communicating pipe 11, the gas in crystallisation chamber 1 can enter in vaporization chamber 2 smoothly, makes the pressure of crystallisation chamber 1 keep balance.
In work, the material that new material and return duct 5 reflux pumps into heat exchanger 8 by circulating pump 12, and the material after heat exchange enters vaporization chamber 2 from inlet tube 7, is advanced into crystallisation chamber 14 times along central tube, and the crystal that crystallisation chamber 1 is formed is discharged from discharge nozzle 6.
