Abstract
The utility model relates to a cooling device in an ammonium nitrate production device. The cooling device structurally comprises a cooling tower, a lithium bromide refrigerator and a circulating water pump. According to the cooling device, steam waste heat serves as a drive heat source of the lithium bromide refrigerator for refrigerating in the production process, steam condensed water is input into the ammonium nitrate production device to cool steam in the device, meanwhile, circulating water output from the cooling tower and heated by steam is cooled, and due to the fact that the cooled circulating water is low in temperature, consumption of the circulating water is reduced and requirements of the production process are met at the same time. The cooling system effectively uses steam energy, does not need electricity for refrigerating, reduces waste of energy, can reduce the consumption amount of the circulating water to 750 tons per hour, saves electricity about 680000 KWh per year, saves water about 65000 tons per year, and can reduce the discharge amount of the circulating water by 20000 tons per year.
Description
Technical field
The utility model relates to the cooling system in a kind of industry, specifically the cooling system in a kind of ammonium nitrate production device.
Background technology
What at present, the method for domestic existing production ammonium nitrate was the most frequently used is pressurization neutralisation.In pressurization neutralisation, the steam pressure producing is in 0.3 MPA left and right, the operations such as these steam can be used for pressurizeing that a section of evaporimeter heating, one section of negative pressure evaporation of ammonium nitrate of neutralising arrangement vacuumizes, ammonia evaporator evaporation ammonia and the preheating of ammonium nitrate flash evaporator, and excess steam can not be utilized effectively, can only discharge as used heat.The mode of this waste heat discharge is by a large amount of industrial circulating waters, heat to be taken away, so just need to consume a large amount of recirculated water, cause the waste of water resource and heat energy, the quantity of steam of the 0.3MPa pressure that for example a set of 400,000 tons/year of ammonium nitrate (pressured neutral process) process units produces is at 24 tons/hour, after using in process of production, also remain the steam of approximately 6 tons/hour, these quantity of circulating water that need are (temperature rise of recirculated water is 8 ℃) about 1600 tons/hour.
Utility model content
The purpose of this utility model is just to provide the cooling system in a kind of ammonium nitrate production device, to solve the waste problem of existing cooling system water resource and heat energy.
The utility model is achieved in that the cooling system in a kind of ammonium nitrate production device, includes:
Cooling tower, be connected with lithium bromide refrigerator with refrigeration outlet pipe by refrigeration water inlet pipe, be connected with ammonium nitrate production device by looping back water pipe, and be connected in water circulating pump, for the recirculated water holding is pressed into described ammonium nitrate production device by water circulating pump, carry out cooling to the steam producing in described ammonium nitrate production device, and by looping back water pipe, the recirculated water after being heated by steam is reclaimed, simultaneously by these heating after recirculated water enter in described lithium bromide refrigerator, carry out cooling after again reclaim storage;
Lithium bromide refrigerator, be connected with described cooling tower with refrigeration outlet pipe by refrigeration water inlet pipe, be connected with described ammonium nitrate production device with steam water pipe by condensate pipe, drive to freeze for the steam that receives described ammonium nitrate production device, and the steam condensate (SC) of generation is inputted in described ammonium nitrate production device, steam is carried out cooling, carry out cooling to the water in described cooling tower simultaneously;
Water circulating pump, is connected with described ammonium nitrate production device with described cooling tower, for the recirculated water of described cooling tower is pressed in described ammonium nitrate production device by periodical feeding pipe.
Described lithium bromide refrigerator has one or more parallel form to be connected in cooling system.
The utility model is by utilizing the steam waste heat in production process to freeze as the driving heat source of lithium bromide refrigerator, and steam condensate (SC) is input in ammonium nitrate production device and carries out cooling to the steam in device, carry out cooling to the recirculated water being heated by steam of exporting in cooling tower simultaneously, because cooled circulating water temperature is lower, in the consumption that reduces recirculated water, meet the needs of production technology.The utility model has effectively utilized steam energy, without freezing by electric power, has reduced the waste of the energy, recirculated water consumption can be reduced to 750 tons/hour, can save electric power approximately 680,000 KWh/, save approximately 6.5 ten thousand tons/year, water, can reduce Circulating water effluent amount and reach 20,000 tons/year.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1, lithium bromide refrigerator, 2, cooling tower, 3, water circulating pump, 4, refrigeration water inlet pipe, 5, refrigeration outlet pipe, 6, periodical feeding pipe, 7, loop back water pipe, 8, steam water pipe, 9, condensate pipe, 10, ammonium nitrate production device.
The specific embodiment
As shown in Figure 1, the utility model includes cooling tower 2, lithium bromide refrigerator 1 and water circulating pump 3.
The low-temperature circulating water of cooling tower 2 interior storages is pressed in ammonium nitrate production device 10 by periodical feeding pipe 6 via water circulating pump 3, steam in ammonium nitrate production device 10 is carried out cooling, and from ammonium nitrate production device 10, the recirculated water after being heated by steam is reclaimed by looping back water pipe 7.Meanwhile, cooling tower 2 carries out the recirculated water input lithium bromide refrigerator 1 after being heated by steam by refrigeration water inlet pipe 4 cooling, and cooled recirculated water is regained.
The quantity of lithium bromide refrigerator 1 can be set to one as required, or arranges many and be connected in parallel in cooling system.
