Embodiment 1:
By taking existing zinc corruption uraturia element as an example, the scheme of the present embodiment is discussed in detail.Existing zinc corruption uraturia element is mating to match
The raw material synergy liquid time processed is longer, and fluctuation of concentration is big；Self priming pump pumps liquid of appreciating and enlarging and easily causes damage, and joint connection in site leather hose
It is more, cause environment to influence；When production increment urea, capacitance liquid level meter instruction is wrong, and live visor is difficult to observe；Molten hopper without
Liquid level facility, with liquid with reference to difficult；Urea particle intensity is low；
Analysis: preparation synergy liquid measure is 2 tons to trial production period synergy liquid reaction kettle 1 every time, and synergy liquid fills two tons every time
Bucket causes in two tons of buckets solution humic acid content difference, urinates finished product because pump intake accesses 1 bottom of synergy liquid reaction kettle
Humic acid content impacts in element, need frequently to adjust metering pump knob under same produce load stablize in finished urea
Quality.
Contain 30% or so bursting type hollow granule in finished urea particle, analyzed through technology, is contained in humic acid material
Caused by insoluble impurity, urine from granulation spray head circumgyration incision be small liquid pearl, due to effect interior impure and in surface tension
Under, hollow granule is formd, finished urea intensity is caused to decline.
During preparing synergy liquid, add microelement after, solution stirred and high temperature after generate foam, synergist adds
It after adding to evaporation section, causes urine to blister at secondary vacuum seperator collector, influences capacitance liquid level meter instruction and deviate, and formed
Urine foam (include and do not allow impurity) easily cause aperture clogs at the top of prilling spry, cause spray head overflow, generated in belt big
The blister particle for measuring peanut grain size, influences urea external quality.
With small-sized self priming pump with standing slot 2 before acidproof hose conveying synergy liquid to metering pump, operating process when trial production
It is complex, and easily production environment is polluted.
During the present embodiment device produces zinc corruption uraturia element, workload control adds synergist about in 18t/h
12Kg/t, former 1 preparation ability of synergy liquid reaction kettle once only meets about 8 hours dosages, therefore carries out more to the synergy liquid reaction kettle 1

80 mesh filter screen of detachable, periodically carries out cleaning cleaning to filter screen；It prevents from a large amount of insoluble impurity from entering to stand in slot 2.
2, synergy liquid ton bucket storage be not easy to keep the temperature, therefore add two volumes be 4t stand slot 2, peripheral hardware steam pipe coil,
It stands synergy liquid temperature in slot 2 and remains 40-50 DEG C, be always ensured that liquid fluidity state；The standing slot 2 has molten simultaneously
Liquid stands effect, and matched solution does not allow impurity to be sink to slot bottom after 10 hours or more standings；Impurity is avoided to enter system, it is right
The external quality of urea impacts.The position of steam pipe coil is to stand to wind from up to down outside slot 2.Tank liquid needs to protect
Good fluidity is held, temperature is controlled at 40-50 DEG C, and the excessively high moisture that will cause of temperature largely evaporates, and synergy liquid concentration changes,
The too low liquid physical state that will cause of temperature changes, poor fluidity
3, to avoid a large amount of foams of solution generation after addition microelement from impacting production system and finished urea, In
A small amount of auxiliary agent is manually added in chute feeder 3 eliminates foam.
4, it adds two centrifugal pumps (dosing pump 4+ feeding engine 5) and transfers synergy liquid with fixed pipelines, reduce manpower, solve simultaneously
It has determined environmental pollution.
It should be noted that the synergy liquid reaction kettle of the present embodiment includes external kettle body, interior autoclave body, in insertion inside autoclave body
Rabbling mechanism, interior autoclave body are located at the inner cavity of external kettle body, insulating layer are additionally provided with before external kettle body and interior autoclave body, and interior autoclave body is clamped
In the upper end of external kettle body, the top of interior autoclave body is equipped with kettle cover, and kettle cover blocks the opening of interior autoclave body, and rabbling mechanism is inserted into from kettle cover
Inside interior autoclave body.The liquid outlet of synergy liquid reaction kettle is located at the bottom end of interior autoclave body, and the inlet of synergy liquid reaction kettle is located at interior kettle
The top of body.
It please join shown in Fig. 1, Fig. 1 is the functional block diagram of process units.The process units of the increment urea of the present embodiment, including
