Abstract
The invention discloses a condensate water recycling system which comprises air heater heat exchangers, flash chambers and a liquid ammonia gas-liquid separation tank. The condensate water recycling system is characterized in that two air heater heat exchangers are connected to the liquid ammonia gas-liquid separation tank through pipelines, two flash chambers are connected to the liquid ammonia gas-liquid separation tank through pipelines, water from a lower outlet of the liquid ammonia gas-liquid separation tank is conveyed to a storage tank by a centrifugal pump through pipeline connection, hot steam of the other outlet of the liquid ammonia gas-liquid separation tank is conveyed to the air heater heat exchangers through the pipelines, a valve is mounted on a pipeline between the liquid ammonia gas-liquid separation tank and the air heater heat exchangers, and a safety valve is mounted at the bottom of the liquid ammonia gas-liquid separation tank. A large amount of hot steam produced in the ammonium phosphate production process is recycled, and the cost is saved.
Description
Technical field
The present invention relates to a kind of recycling device, particularly relate to a kind of recycling device of water of condensation.
Background technology
In my company's phosphorus ammonium production process, concentration process can produce much a large amount of condensing water vapors, a large amount of condensing water vapors is discharged to atmospheric layer owing to can not get reasonable effective Collection and use, a large amount of hot steams and current are virtually caused to lose, cause production cost higher, resource can not get effective recycling, forms waste.
Summary of the invention
In order to overcome above-mentioned Problems existing, the invention provides a kind of condensate water circulatory and using system, can by phosphorus ammonium in process of production, a large amount of hot steam of appearance and water are effectively recycled, and save cost.
The object of the invention is to be realized by following scheme:
A kind of condensate water circulatory uses system, comprise: calorifier heat exchanger, flashing chamber, liquefied ammonia knockout drum, it is characterized in that being: two calorifier heat exchangers are connected to liquefied ammonia knockout drum by pipeline, two flashing chambers are connected to liquefied ammonia knockout drum by pipeline, go out saliva under described liquefied ammonia knockout drum and be transported to storage tank through pipeline chaining by impeller pump, another of liquefied ammonia knockout drum exports hot steam by pipeline transportation to calorifier heat exchanger, described liquefied ammonia knockout drum is provided with valve to the pipeline of calorifier heat exchanger, described liquefied ammonia gas-liquid separation pot bottom is equipped with safety valve.
A kind of condensate water circulatory of the present invention uses system, its beneficial effect is: can effectively a large amount of hot steams produced in production process be carried out being separated into hot G&W, hot gas returns to calorifier heat exchanger by pipeline and recycles, the water separated is transported to the water needed for the production of storage tank phosphorus supply ammonium by impeller pump, form recycle, cost-saved, reduce heat dissipation.
Accompanying drawing explanation
Fig. 1 is present invention process schematic flow sheet.
Wherein: 1, calorifier heat exchanger, 2, flashing chamber, 3, liquefied ammonia knockout drum, 4, impeller pump, 5, storage tank; 6, safety valve.
Embodiment
As shown in Figure 1: a kind of condensate water circulatory uses system, comprise: calorifier heat exchanger 1, flashing chamber 2, liquefied ammonia knockout drum 3, it is characterized in that being: two calorifier heat exchangers 1 are connected to liquefied ammonia knockout drum 3 by pipeline, two flashing chambers 2 are connected to liquefied ammonia knockout drum 3 by pipeline, described liquefied ammonia knockout drum goes out saliva 3 times and is transported to storage tank 5 through pipeline chaining by impeller pump 4, another of liquefied ammonia knockout drum 3 exports hot steam by pipeline transportation to calorifier heat exchanger 1, described liquefied ammonia knockout drum 3 is provided with valve to the pipeline of calorifier heat exchanger, described liquefied ammonia gas-liquid separation pot bottom is equipped with safety valve 6.
The present invention implements in the following manner: by the outlet of two calorifier heat exchangers 1 by pipeline communication to the entrance of liquefied ammonia knockout drum 3, calorifier heat exchanger 1 adopts two, both can be according to actual needs, when there is the abnormal or maintenance down of work for one, another can work on, also can two work simultaneously and alleviate respective burden, pipeline used adopts aluminum alloy material, both can be high temperature resistant, can corrosion-resistantly get rusty again, ensure the tightness that hot steam is transported, the hot steam of generation is also transported to the entrance of liquefied ammonia knockout drum 3 by two flashing chambers 2 by pipeline, two flashing chambers 2 are divided into I effect flashing chamber and II effect flashing chamber, two flashing chambers 2 and two calorifier heat exchangers 1 can use a liquefied ammonia knockout drum 3 jointly, save an equipment, pipeline adopts aluminium alloy stainless steel equally, the water separated of liquefied ammonia knockout drum 3 by lower outlet through piping by an impeller pump 4 by water transport to storage tank 5, impeller pump 4 can adopt periodic running, by water transport to storage tank 5, reuse in water phosphorus supply ammonium production process inside storage tank 5, achieve the recycle of water, the hot gas that liquefied ammonia knockout drum 3 is separated is transported to the entrance of calorifier heat exchanger 1 through piping by upper outlet, the circulation achieving hot gas utilizes again, the process operation flow process of whole system is such, in phosphorus ammonium production process, used equipment calorifier heat exchanger 1 and flashing chamber 2 can produce a large amount of hot steams in operational process, the hot steam that this two complete equipment produces enters into after liquefied ammonia knockout drum 3 carries out gas-water separation through piping, water after isolated is transported in storage tank 5 through impeller pump 4 by pipeline, the heat steam separated directly enters into the entrance recycle of calorifier heat exchanger through piping.
The equipment technical parameters wanted required for the present invention is as shown in the table:
Can be drawn by above embodiment, two calorifier heat exchangers can use simultaneously, also can be used alone, for overhaul of the equipments and later expanding production prepare, have very strong handiness, structure of the present invention is simple, effectively the hot steam be discharged can be carried out recycling, both production cost was saved, also emissions reduction.
Last it is noted that above embodiment only in order to illustrate the present invention and and unrestricted technical scheme described in the invention; Therefore, although this specification sheets with reference to each above-mentioned embodiment to present invention has been detailed description, those of ordinary skill in the art should be appreciated that and still can modify to the present invention or equivalent to replace; And all do not depart from technical scheme and the improvement thereof of the spirit and scope of the present invention, all should be encompassed in right of the present invention.
