Description
Technical field
This utility model belongs to phosphorus production technical field, is specifically related to remove in a kind of phosphorus production the device of light component.
Background technology
Common phosphorus production mainly utilizes electric furnace process to produce by yellow phosphorus Ore, anthracite, Silicon stone, and common yellow phosphorus is high due to heavy metal, other impurity content, is unfavorable for that yellow phosphorus carries out refinement processing.
Current domestic high-purity yellow phosphorus production technology removes heavy metal (heavy constituent) in yellow phosphorus mainly by principles of rectification, remove light component process equipment without reference to.Actual production process contains the solid suspensions (light component) such as impurity such as charcoal, silicon, gangue due to yellow phosphorus self, if light component is continuously increased accumulation in rectification production process, not only can affect high-purity yellow phosphorus technological parameter and efficiency, as can not get solving to cause the blocking of rectification tower reactor to cause industrial accident for a long time.
Summary of the invention
The purpose of this utility model provides the device removing light component in a kind of phosphorus production, and this apparatus structure is simple, and reasonable in design, extraction concise in technology, free rate are high, safe and reliable.
For solving above-mentioned technical problem, this utility model be the technical scheme is that the device removing light component in a kind of phosphorus production, including rectification tower reactor, is arranged over catcher within rectification tower reactor, it is connected to light Fraction collection groove by pipeline bottom catcher, pipeline is provided with extraction valve；Described device is additionally provided with raw material tank, and raw material tank is sequentially connected to bottom and the packed tower top of rectification tower reactor by pipeline and valve.
Described catcher is inverted pyramidal structure, a diameter of 200mm of this conical lower portion, and catcher lower end utilizes pipeline to be connected with light Fraction collection groove.
Described catcher is arranged on the position of rectification tower reactor internal height 70%.Can ensure that this position extraction does not interferes with whole rectification tower reactor technological parameter, tower reactor internal heating coils will not cause potential safety hazard because of the too low exposed hot operation of liquid level simultaneously.It is arranged on tower reactor center.
Described catcher, light Fraction collection groove, rectification tower reactor are integrated design, all reach vacuum state, can ensure continuous extraction in the case of not affecting tower tower reactor vacuum pressure during extraction.When tower reactor liquid level exceeds the conical surface, the floating light component in top can be expelled to light Fraction collection groove along pipeline by automatic overflow to catcher.
The structure design of this device is simple, is increased without the extraction of other auxiliary equipments, safe ready.
Device described in employing carries out the method for light component extraction, concretely comprises the following steps:
In yellow phosphorus distillation process, when the liquid level in still reaches the height at catcher place, open extraction valve, make light component be flowed in collecting tank by catcher and pipeline；And open raw material tank to the valve in rectifying column bottom portion, feed rate controls at 200-400 kg/h, in making still, liquid level slowly rises, variations in temperature≤5 DEG C in still are controlled during extraction, pressure change≤2kpa, rectification tower reactor its top feed and light component extraction flow keep constant, and extraction completes to stop afterwards from raw material tank to rectifying column still bottom feed.
Light component extraction free rate reach 90% and above time stop extraction.
The time of light component extraction is 0.5-1 hour, and extraction is once and continuous extraction of need not stopping weekly.
During extraction, all valve operations, flow-control use pneumatically or electrically regulation valve remotely to control.Reduce labor intensity to avoid because leakage causes personnel to injure simultaneously.
This device due to while to light component extraction tower reactor bottom feed also synchronize to carry out, by accurately controlling feed rate, there is not large change in rectification bottom temperature, pressure, it is ensured that rectification evaporation capacity does not changes, and reaches to produce continuously raising yield purpose.
And during extraction, pass through bottom feed, it is ensured that tower reactor liquid level slowly goes up and makes the floating light component in top step into catcher smoothly from pipeline extraction, and light component extraction free rate can be made to reach 90%, it is ensured that safety in production.
Can effectively be removed the light component in phosphorus production by this device, improve the quality of yellow phosphorus, it is to avoid in production process, the blocking of light component causes security incident.
