Abstract
The utility model discloses an ammonia processed product cooling system which comprises a high tower, a first cooler, a second cooler and a neutralization reactor absorbing ammonia. A pipeline of an air inlet of the first cooler is provided with an ammonia cooling chamber. The ammonia cooling chamber is provided with an ammonia liquid inlet, an ammonia gas outlet, an air inlet and an air outlet. The ammonia gas outlet is connected with a pipeline and communicated with the neutralization reactor. The air inlet of the ammonia cooling chamber is provided with an air blower. The air outlet of the ammonia cooling chamber is connected with an air inlet of the second cooler through a pipeline. Compared with the prior art, the feature that ammonia liquid can absorb heat when the ammonia liquid is converted to ammonia gas after release of pressure is adopted, air in the ammonia cooling chamber can be cooled, and the cooled air is conveyed to the coolers for cooling a product so that particle temperature of the product can be reduced; and the evaporated ammonia gas can be conveyed to the neutralization reactor for a neutralization reaction so that ammonia loss is avoided and after the package temperature is reduced, blocking and pulverization of the product in summer can be reduced.
Description
Technical field
The utility model relates to the fertilizer processing technique field, particularly a kind of ammonia converted products cooling system.
Background technology
When summer, temperature was about 80～90 ℃ after ammonia converted products particle came out from high tower, mainly undertaken air-cooled by cooler, the wind that blower fan is extracted out is hot blast, can not effectively reduce the object surfaces temperature, it is that the temperature difference is very little that the internal and external temperature of object is more or less the same, and heat is transmitted very slow, does not reach cooling purpose at short notice.The moisture content that packing of product temperature height dissolves in the time of can causing product high temperature is separated out after cooling, thereby cause the caking efflorescence, so control package temperature, do not increasing the situation decline low production package temperature of bigger investment, the wind that enters cooler by cooling reaches the purpose that reduces product temperature.
China's utility model patent 201120357905.6 discloses a kind of fertilizer cooling device, it comprises drum-type cooling machine, blower fan and air-conditioning, be provided with blade in the drum-type cooling machine, an end is provided with blower fan, the other end is provided with air inlet and air-conditioning, conditioned surface is to the air inlet of drum-type cooling machine.This cooling device has played the effect of lowering the temperature to the product pellet in the cooler, but capital invested is big, blows a cold wind over air-conditioning, has increased the consumption of electric energy.
Summary of the invention
The purpose of this utility model is a kind of ammonia converted products cooling good cooling results will be provided and invest little ammonia converted products cooling system.
The utility model is implemented according to following technical scheme:
A kind of ammonia converted products cooling system, the neutralization reactor that comprises high tower, first cooler, second cooler, absorption ammonia, the ammonia cold house is set on the pipeline of the air inlet of described first cooler, the ammonia cold house is provided with liquefied ammonia entrance, gas ammonia outlet, air inlet and air outlet, gas ammonia outlet connecting pipe road feeds neutralization reactor, the air inlet of described ammonia cold house arranges air blast, and the air outlet of ammonia cold house connects the air inlet of second cooler by pipeline.
Further, be provided with the cold pipe of disc type ammonia in the described ammonia cold house.
Further, the cold pipe of described ammonia is that the seamless pipe of Ф 38 * 3 is made by specification.
Compared with prior art, the utility model can absorb the characteristic of heat when utilizing the liquefied ammonia step-down to become gas ammonia, the air in the ammonia cold house is cooled off, and sends into cooler product is cooled off, thereby reduce the product pellet temperature; The gas ammonia of evaporation enters and supplies neutralization reaction usefulness in the neutralization reactor, does not have the ammonia loss, behind the reduction package temperature, has reduced the caking efflorescence of product in summer.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is further described, is used for explaining the utility model in illustrative examples and the explanation of this utility model, but not as to restriction of the present utility model.
A kind of ammonia converted products cooling system as shown in Figure 1, the neutralization reactor 9 that comprises high tower 1, first cooler 2, second cooler 3, absorption ammonia, ammonia cold house 4 is set on the pipeline of the air inlet of first cooler 2, ammonia cold house 4 is provided with liquefied ammonia entrance 5, gas ammonia outlet 7, air inlet and air outlet, gas ammonia exports 7 connecting pipes and feeds neutralization reactor 9, the air inlet of ammonia cold house 4 arranges air blast 8, and the air outlet of ammonia cold house 4 connects the air inlet of second cooler 3 by pipeline.
Temperature was higher after the ammonia converted products came out from high tower, send into first cooler 2 and second cooler and carry out cooling processing, 4 liquefied ammonia entrances 5 feed liquefied ammonia from the ammonia cold house, in ammonia cold house 4, handle through step-down, because the liquefied ammonia step-down can absorb heat when becoming gas ammonia, temperature reduces in the ammonia cold house 4, by air blast extraneous hot blast being blown into ammonia cold house 4 cools off, cooled air is blown into first cooler 2 and second cooler 3 cools off ammonia converted products particle respectively, liquefied ammonia is evaporated to gas ammonia and enters the neutralization reactor 9 that fills the absorption gas ammonia from gas ammonia outlet 7, for producing the reuse of ammonia converted products.
Be provided with the cold pipe 6 of disc type ammonia in the ammonia cold house 4, adopt the cold pipe 6 of disc type ammonia can increase air and the contact area of the cold pipe 6 of ammonia in the ammonia cold house 4, the cooling velocity of quickening air.
Because ammonia belongs to noxious material, the cold pipe of ammonia is that the seamless pipe of Ф 38 * 3 is made by specification, prevents that gas ammonia from leaking the security incident that causes.
From actual motion, the cold wind temperature of coming out in the ammonia cold house is lower 8-10 ℃ than environment temperature, reduces 6-8 ℃ to second cooler, 3 inlet temperatures than environment temperature, and certain effect has been played in cooling to product.After using cooling air, packing of product temperature has reduced about 2～5 ℃ than without cooling air, in summer the efflorescence caking that reduces product has been played certain effect.The utility model does not need to increase other equipment simultaneously, has reduced cost of investment.
The technical solution of the utility model is not limited to the restriction of above-mentioned specific embodiment, and every technology distortion of making according to the technical solution of the utility model all falls within the protection domain of the present utility model.
