Abstract
The utility model belongs to the field of urea production equipment, and particularly relates to a urea pump sealing water circulating device which comprises a desalted water supplementing pipe. The desalted water supplementing pipe is connected with a water inlet pipe, the water inlet pipe is connected with inlets of pump sealing water pipes, outlets of the pump sealing water pipes are connected onto a return water pipe, an end of the return water pipe is respectively connected to an accident pool and an underground tank, the underground tank is connected onto a water delivery pipe by a sealing water pump, and an end of the water delivery pipe is connected to the accident pool. The urea pump sealing water circulating device has the advantages that the urea pump sealing water circulating device is simple in structure and convenient to implement, and sealing water used by pumps is drained into the underground tank via pipelines and is used as sealing water again after being cooled, so that water resources are saved, discharge of ammonia-containing wastewater is prevented, pressure caused by discharge standards is relieved, a large quantity of desalted water can be saved, environments are protected, and the urea pump sealing water circulating device has a certain economic benefit and a certain environmental benefit; an ammonia nitrogen monitoring sensor is arranged on a pipeline which is arranged on a return water pipeline and is positioned at the front of the underground tank, so that the used sealing water can be drained into the accident pool or can be recycled again according to different concentrations of the used sealing water owing to a detector.
Description
Technical field
The utility model belongs to the urea production equipment field, is specifically related to a kind of urea pump sealing water circulator.
Background technique
Current, country more and more payes attention to environmental protection work, and can this be related to the significant problem that realize sustainable development and national economy.Nitrogen fertilizer production enterprise is all towards target hard-working pollution-free, zero-emission.At present, enterprise is just used once the packing seal of urea solution ammonia pump is general, and waste water directly is discharged to blow-off line.Ammonia-containing water is the important object of environmental improvement, if can make to seal water circulation use, has both avoided the discharge of ammonia-containing water, has alleviated the pressure of qualified discharge, can save a large amount of demineralized waters again, brings the change of economic benefit.Urea production producer all can face such problem---and the design of sealing water circulation use is undoubtedly the direction that each producer makes great efforts.
The model utility content
The utility model exists the general just use of urea solution ammonia pump packing seal once, to cause this problem of environmental pollution and water resource waste for prior art, proposes a kind of urea pump sealing water circulator.
The technical solution of the utility model is: a kind of urea pump sealing water circulator, comprise that demineralized water supplements water pipe, demineralized water supplements water pipe and is connected with intake pipe, intake pipe is connected with the import of pump sealing water pipe, the outlet of pump sealing water pipe is connected on return pipe, one end of described return pipe is connected respectively to accident pool and sloptank, and sloptank is connected on conduit pipe through water-sealed pump, and an end of conduit pipe is connected to accident pool.
Described urea pump sealing water circulator, at least connect 3 pumps on described return pipe, also connect ammonia pump sealing water pipe on return pipe.
Described urea pump sealing water circulator, be equipped with the ammonia nitrogen concentration monitoring sensor at return pipe near an end of sloptank.
Described urea pump sealing water circulator, be equipped with cooler near on the conduit pipe of water-sealed pump, and cooler is just used water cooling.
The beneficial effects of the utility model are: 1. the utility model is simple in structure, enforcement is convenient; pump is advanced to sloptank with the sealing water of crossing with tuber drainage; after cooling, continue to use as sealing water; save water resources, simultaneously, both avoided the discharge of ammonia-containing water; alleviated the pressure of qualified discharge; can save a large amount of demineralized waters again, protect again environment, there is certain economic benefit and environmental benefit.
2. the utility model is provided with the NH 3 sensor on water return pipeline on the pipeline before sloptank, detector makes and uses sealing water later to enter accident pool according to the difference of concentration, perhaps proceed circulation, guaranteed that sealing water is unsaturated, can safe being sealed.
3. the utility model is equipped with cooler near the conduit pipe near sloptank, just water is as freezing mixture for cooler, and cooler guarantees for the circulating water temperature of sealing lower, avoids because the sealing coolant-temperature gage is high, reduce sealing effect, improved the quality of sealing.
The accompanying drawing explanation
Fig. 1 is the utility model overall structure schematic diagram;
In figure, 1 is the demineralized water water-adding pipe, and 101 is demineralized water moisturizing pipe valve, 2 is conduit pipe, and 3 is return pipe, and 4 is pump sealing water pipe, 401 inlet valves for pump sealing water pipe, 402 outlet valves for pump sealing water pipe, 5 is ammonia pump sealing water pipe, 501 is ammonia pump sealing water pipe valve, and 6 is the NH 3 sensor, and 7 is sloptank, 701 is the sloptank inlet valve, 8 is water-sealed pump, and 9 is cooler, and 10 is accident pool.
Embodiment
Embodiment 1: in conjunction with Fig. 1, a kind of urea pump sealing water circulator, comprise that demineralized water supplements water pipe, demineralized water supplements water pipe and is connected with intake pipe, intake pipe is connected with the import of pump sealing water pipe, the outlet of pump sealing water pipe is connected on return pipe, one end of described return pipe is connected respectively to accident pool and sloptank through threeway, be provided with valve between accident pool and threeway, be provided with the sloptank valve between threeway and sloptank, sloptank is connected on conduit pipe through water-sealed pump, and an end of conduit pipe is connected to accident pool.Connect 3 pumps on described return pipe, also connect ammonia pump sealing water pipe on return pipe.
An end at the close sloptank of return pipe is equipped with the ammonia nitrogen concentration monitoring sensor; Near on the conduit pipe of water-sealed pump, cooler is installed, cooler is just used water cooling.
Embodiment 2: without figure, the part identical with embodiment 1 do not repeat, and different is to connect 60 pumps on described return pipe, also connects ammonia pump sealing water pipe on return pipe.
Working method: demineralized water is transported to pump through pipeline, the pump memory is sealed, used demineralized water flows into sloptank through return pipe, then being transported to cooler through water-sealed pump carries out cooling, coolingly by conduit pipe, be transported to pump, when the NH 3 Sensor monitoring on return pipe is higher to the demineralized water ammonia nitrogen concentration, control gear can cut out the sloptank valve, open the valve that leads to accident pool, flow directly into accident pool.
