The cooling and dehumidifying air cooling device for the fertilizer is arranged at an air inlet of a rotary drum air cooler or a fluidized bed air cooler, and can reduce temperature and humidity of fertilizer cooling air and improve cooling and dehumidifying effects; and the device is simple in structure, low in energy consumption and pollution-free.

Description

A kind of fertilizer cool-down dehumidification air cooling apparatus
Technical field
The utility model relates to a kind of production unit of chemical fertilizer, especially a kind of fertilizer cool-down dehumidification air cooling apparatus.
Background technology
The general modes such as revolving cylinder air cooling, fluidized bed air cooling that adopt of conventional fertilizers cooling, but in summer because air self-temperature height and moisture content are big, fertilizer cooling performance difference and moisture absorption deliquescence in cold easily influence quality product.Also there are pair air cooling-down, dehumidifying to be used for composite fertilizer's cooling at present; But because it adopts compressor unit, freon refrigeration energy consumption higher; And just to air cooling-down, wherein cooled air moisture content is still higher, when reaching cooling performance and solution moisture absorption problem not yet in effect.
Summary of the invention
The purpose of the utility model provides a kind of fertilizer cool-down dehumidification air cooling apparatus that reduces the temperature and humidity of cooling air.
For achieving the above object, the utility model adopts following technical scheme:
The described a kind of fertilizer cool-down dehumidification air cooling apparatus of the utility model; Comprise housing, be arranged on the liquefied ammonia vaporizer in the housing inner chamber, the input terminus of liquefied ammonia vaporizer connects the liquefied ammonia pipeline, and the output terminal of liquefied ammonia vaporizer connects the gas ammonia pipeline; Housing is provided with gas inlet and air; It is characterized in that: said gas inlet connects gas blower, and said air is connected to airheater through moisture trap, and said airheater comprises heater case and is arranged on the heating coil in the heater case inner chamber; The two ends of heating coil connect hot water input tube and return water pipe respectively; Said heater case is provided with input aperture and delivery port, and said input aperture is through the air output terminal of pipe connection to moisture trap, and delivery port arrives the fertilizer water cooler through pipe connection.
This device utilizes the liquefied ammonia that gasifies in the Ammonia Production that air is cooled to temperature 5-10 ℃; Air wherein water vapor after cooling reaches capacity and separates out liquid water, separates the moisture content of wherein separating out through a gravity, silk screen, the comprehensive dehumidifier of pharmaceutical chemicals again.Air behind the separation moisture content still is in the moisture-saturated state; Utilize in the production equipment heating of the hot water behind the vapor condensation through an airheater, AT is risen to 10-15 ℃ make it reach undersaturated condition to let it get into refrigerating unit again fertilizer is cooled off.Patent device has following advantage: utilize ammonia still process recovery heat energy cooling air in the Ammonia Production, belong to energy-conservation process; Adopt gravity, silk screen, the triple comprehensive dehumidifying of pharmaceutical chemicals, the moisture content separation efficiency is high; Air after the dehumidifying heats up and makes it unsaturated, has solved back segment fertilizer cooling moisture absorption problem, and what adopt simultaneously is steam condensate heating in the production equipment, reclaims heat energy and belongs to energy-conservation process.This fertilizer cool-down dehumidification air cooling apparatus is installed in the blast inlet place of revolving cylinder air-cooler or fluidized bed air water cooler, can reduces the temperature and humidity of fertilizer cooling air, improve the effect of cool-down dehumidification; This apparatus structure is simple, power consumption less, pollution-free.
Description of drawings
Fig. 1 is the structural representation of an embodiment of the utility model.
Embodiment
As shown in Figure 1; The described a kind of fertilizer cool-down dehumidification air cooling apparatus of the utility model comprises housing 1, is arranged on the liquefied ammonia vaporizer 2 in housing 1 inner chamber; The input terminus of liquefied ammonia vaporizer 2 connects liquefied ammonia pipeline 3; The output terminal of liquefied ammonia vaporizer 2 connects gas ammonia pipeline 4, liquefied ammonia through liquefied ammonia vaporizer 2 time with housing 1 in the air heat exchange, liquefied ammonia becomes gas ammonia from 4 recovery of gas ammonia pipeline.
Housing 1 is provided with gas inlet 5 and air 6; Said gas inlet 5 connects gas blower 7; Said air 6 is connected to airheater through moisture trap 8, and the input terminus of moisture trap 8 connects air 6, and the output terminal of moisture trap 8 connects airheater.Said airheater comprises heater case 9 and is arranged on the heating coil 10 in heater case 9 inner chambers; The two ends of heating coil 10 connect hot water input tube 11 and return water pipe 12 respectively; Said heater case 9 is provided with input aperture 13 and delivery port 14; Said input aperture 13 is through the air output terminal of pipe connection to moisture trap 8, and delivery port 14 arrives fertilizer water cooler 15 through pipe connection.
During use, gas blower blows into natural wind, liquefied ammonia vaporizer 2; The cooled air of lowering the temperature gets into moisture trap 8 through air 6; Moisture content is discharged from the water port of moisture trap 8, and the later air that dehumidifies gets into heater case 9 through input aperture 13, in heater case 9 inner and heating coil 10 heat exchange; AT is risen to 10-15 ℃ that is fit to cooling fertilizer, send into the cooling that is used for fertilizer in the fertilizer water cooler 15 at last.
