3, the waste cooling water is very big, and this device is also undesirable to the cooling effect of first ammonium liquid simultaneously, has limited the raising of urea production ability to a certain extent.
The purpose of this utility model provides an a kind of absorption cooler cooling back installation and copper cleaning device heating power network, can save steam effectively, save the recirculated cooling water that the urea cooling tower comes, save cold soft water, improve the cooling effect of urea plant first ammonium liquid, the urea production ability is improved.
The technical solution of the utility model is that absorption cooler cooling back installation in the urea plant and the copper cleaning device in the ammonia production system are formed the heating power network, this heating power network comprises the copper cleaning device, one absorption cooler and heat-exchanger pump, between an absorption cooler and heat-exchanger pump, be provided with the hot water pipeline and the heat-exchanger pump output channel of the water pump that reduces phlegm and internal heat, on the water pump hot water pipeline that reduces phlegm and internal heat, also be provided with extraneous hot water pipeline and valve and cold soft water and replenish pipeline and valve, on the water pump hot water pipeline that reduces phlegm and internal heat that goes between the additional pipeline of extraneous hot water pipeline and cold soft water, also establish a valve, a hot water pipeline and a water return pipeline that returns from the copper cleaning device that removes the copper cleaning device also is installed on the water pump hot water pipeline that reduces phlegm and internal heat, on the water pump hot water pipeline that reduces phlegm and internal heat between hot water pipeline that removes the copper cleaning device and the water return pipeline, also establish a shortcut valve, this heating power network is also respectively being established a valve on the hot water pipeline that removes the copper cleaning device He on the water return pipeline, can cut away copper easily and wash the former flow process of heating power network recovery, thereby make an absorption cooler cooling back installation and copper cleaning device form closed cycle heating power network.
The operation principle of this heating power network is: the generation heat of urea plant absorption system first ammonium is by behind the absorption cooler heat cycles hot water, the shortcut valve closing, circulating hot water is along reducing phlegm and internal heat water pump hot water pipeline and go copper cleaning device hot water pipeline to enter the copper cleaning device, copper liquid is heated, thereby reduced copper and washed steam consumption in the regenerative process, cooled off by heat absorption behind the circulating hot water process copper cleaning device, enter the water pump hot water pipeline that reduces phlegm and internal heat along water return pipeline again, small part hot water is along going extraneous hot water pipeline to discharge, replenish pipeline from cold soft water simultaneously and replenish a part of cold soft water, make circulating hot water keep balance, most of circulating hot water enters an absorption cooler through heat-exchanger pump pressurization back by the heat-exchanger pump output channel again, thereby saved the recirculated cooling water that the urea cooling tower comes, after the hot water that is cooled off by the copper cleaning device turns back to an absorption cooler, absorb again first ammonium liquid generation heat and by temperature raising, remove copper cleaning device heating copper liquid after the temperature raising again and be cooled, thereby constitute closed cycle heating power network, after forming closed cycle, owing to improved but effect of urea plant first ammonium liquid cooling, thereby the urea production ability is improved, and output increases.
The utility model has the advantages that; (1) saves steam.The copper cleaning device is heated by the hot water that original Steam Heating becomes an absorption cooler cooling back installation after realizing the heating power network, so save steam more than 80%, (2) save the recirculated cooling water that the urea cooling tower comes, an absorption cooler cooling back installation is cooled off by recirculated cooling water cooling the becoming copper cleaning device heat absorption that former employing urea cooling tower comes after realizing the heating power network, so can all save the recirculated cooling water that the urea cooling tower comes; (3) increasing urea production, behind the realization heating power network, is that institute can increase production more than 15% so that urea production improves owing to improved the cooling effect of urea plant first ammonium liquid.
Below in conjunction with accompanying drawing this utility model is described further.
Accompanying drawing is a structural representation of the present utility model.
