Description
Technical field
The utility model belongs to urea recovery technology field, specifically, relates to a kind of substandard products urea recovery and processing system.
Background technology
In the production technique of chemical enterprise, the production of urea can not produce that caking fertilizer, the particle bonding of carbamide dust, lower margin fertilizer, Moisture high UCL is fertile with avoiding, the waste material such as unacceptable product in wrapping process, this this waste material can not be served as product treatment, can not directly recycle, time one is long, waste material be accumulated as a difficult problem.Certainly the enterprise also having sends to production composite fertilizer etc. preferably these underproof waste material screening parts, but finally all can there is the waste material not directly utilizing to exist, if waste material is discarded, first can become an environmental issue, polluting the environment, cause that ammonia nitrogen exceeds standard etc., is secondly to cause the loss of product or waste for no reason, consume and can increase, production cost also can rise.
Utility model content
For solving above technical problem, the purpose of this utility model is to provide a kind of substandard products urea recovery and processing system, after the contaminant filter in substandard products urea being removed, recycles.
The utility model object is achieved in that a kind of substandard products urea recovery and processing system, its key is: comprise dissolving tank, subsider, pump and receiving tank, described dissolving tank, subsider, pump and receiving tank are connected successively by pipeline, in described dissolving tank, be provided with rough filtering device, the liquid-in pipe of this dissolving tank accesses described rough filtering device, in described subsider, be provided with fine filtering device, the liquid-in pipe of this subsider accesses described fine filtering device.
Adopt said structure, to the steam condensate that passes into 60 DEG C of left and right in dissolving tank, urea is dissolved, and tentatively filter by rough filtering device, the large particulate matter containing in substandard products urea is filtered, then starting agitator fully stirs, after static half hour, feed liquid is passed into the fine filtering device in subsider, after tiny contaminant filter, flow into subsider, again leave standstill about 2 hours, finally by feed liquid by being pumped into receiving tank, recycle.
In above-mentioned dissolving tank, be provided with agitator, the liquid-in pipe of described dissolving tank comprises waste material liquid-in pipe and steam condensate liquid-in pipe, and this waste material liquid-in pipe and steam condensate liquid-in pipe all access described rough filtering device.
Adopt said structure, waste material and steam condensate all pass into rough filtering device, and steam condensate, to waste material flow wash dissolving, makes its dissolving more abundant, and agitator can further promote the dissolving of waste material.
Above-mentioned rough filtering device is positioned at the top of described dissolving tank, and described fine filtering device is positioned at the top of described subsider.
Adopt said structure, rough filtering device and fine filtering device are arranged on respectively the top of dissolving tank and subsider, and the taking-up of being convenient to rough filtering device and fine filtering device is cleaned.
Above-mentioned rough filtering device is the filtering net that 50 object woven wires are made, and described fine filtering device is the filtering net that 300 object Stainless Steel Cloths are made.
Adopt said structure, rough filtering device can ensure large granular impurity to filter, and fine filtering device can ensure the filtration of fine impurities.
The bottom of above-mentioned dissolving tank and subsider is equipped with scum pipe, and this scum pipe is provided with by-pass valve control.
Adopt said structure, all have standing process in dissolving tank and subsider, while leaving standstill, bottom land can accumulate a large amount of throw outs, and throw out can be discharged by deslagging tank.
The leakage fluid dram of above-mentioned dissolving tank is positioned at the bottom of this dissolving tank sidewall.
Adopt said structure, the discharge feed liquid of leakage fluid dram more than try one's best, can also prevent that standing throw out from discharging by leakage fluid dram, affects treatment effect.
Beneficial effect:
A kind of substandard products urea of the utility model recovery and processing system, had both solved the unmanageable pressure of waste material, had reduced environmental pollution, reached the object of saving energy and reduce the cost, turning waste into wealth, also reduced the production cost of urea product, the enforcement of this technology is simultaneously taken up an area few, reduced investment, operation is simple.
