Abstract
The utility model belongs to the field of organic fertilizers, and discloses a device for recycling waste liquid ammonia tail gas. The device comprises a tubular ammonia acid reactor (1), a rotor drum granulator (2) and a waste liquid ammonia tail gas collecting tank (3). The device is characterized by also comprising an organic fertilizer composting tank (8), wherein a plurality of rows of air injection pipelines (6) flush with the ground are arranged at the bottom of the organic fertilizer composting tank (8); upward air holes (7) are drilled on each air injection pipeline (6) at intervals; the waste liquid ammonia tail gas collecting tank (3) is communicated with the air injection pipelines (6) through a draught fan (4) and a delivery pipeline (5); and waste liquid ammonia tail gas is charged into organic fertilizer raw material piles from bottom to top through the air holes (7) in the air injection pipelines (6). The device is simple in structure, easy and convenient to operate and low in production cost, and can directly recycle the waste liquid ammonia tail gas produced in compound fertilizer production.
Description
Technical field
The utility model belongs to the organic fertilizer field, relates in particular to a kind of waste liquid ammonia tail gas recycle use device.
Background technology
The propylhomoserin tubular reactor is utilized in the compound fertilizer granulating skilled industry production and widely applies at present, and in the control of propylhomoserin reaction process, liquefied ammonia is slightly excessive, and liquefied ammonia is a kind of high concentration liquid nitrogenous fertilizer, and nitrogenous 83.3%.On the one hand be in order to guarantee that vitriolic fully reacts, to guarantee the finished product pH value at zone of reasonableness, excessive slightly on the other hand liquefied ammonia can be further in and the acidity of monoammonium phosphate in the raw material.Because of excessive liquefied ammonia is arranged, will produce waste liquid ammonia tail gas in the drum granulating, every cube of waste liquid ammonia tail gas contains 0.5% ammonia nitrogen.To the processing of waste liquid ammonia tail gas, generally be through directly discharging through chimney behind the water washing tail gas, not only wasted resource but also contaminate environment; Be to carry out harmless treatment in addition, but bring processing cost higher like this through treating plant or tail gas treatment device.Handle the superfluous ammonia of reaction in the propylhomoserin tubular reactor how simple and practically, also do not have relevant TP report at present.
The utility model content
The purpose of the utility model provide a kind of simple in structure, easy and simple to handle, production cost is low, the device that can the waste liquid ammonia tail gas that produce in the production composite fertilizer directly be recycled.
The purpose of the utility model is to realize through following technical scheme: the device that a kind of waste liquid ammonia tail gas recycle is utilized; Comprise tubular type propylhomoserin reactor drum, rotary drum granulator, waste liquid ammonia exhaust collection jar; Also comprise fertilizer compost pond; Bottom, described fertilizer compost pond is provided with the many rows jet pipe that flushes with ground, is drilled with eyelet pore up at interval on the jet pipe, and described waste liquid ammonia exhaust collection jar is connected with jet pipe through induced draft fan and transport pipe; The pore of waste liquid ammonia tail gas through being provided with on the said jet pipe fills in the fertilizer stockpile from the bottom up.
The said jet pipe of the utility model is for being arranged in parallel, and its distance apart is 1.5 m.
The said diameter that is arranged on the pore on the jet pipe of the utility model is 4～6mm, and the distance apart between the pore is 1m.
Beneficial effect: compared with prior art; Be drilled with eyelet pore up at interval on the many rows jet pipe that flushes with ground and the jet pipe of the utility model through being arranged on fertilizer compost pond bottom, under the induced draft fan effect; With the waste liquid ammonia tail gas that produces in the production composite fertilizer; Fill into from the bottom up in the fertilizer stockpile of having accomplished fermentation for the first time, make waste liquid ammonia tail gas and fertilizer raw materials mix, be used for increasing the content of nitrogen in the fertilizer raw material; C/N ratio (C/N) when making fertilizer raw material compost fermentation drops to suitable (20～25): 1, guarantee that the fertilizer raw material thoroughly becomes thoroughly decomposed.The utility model is simple in structure, easy and simple to handle, and production cost is low, needn't do any processing to waste liquid ammonia tail gas and just can directly recycle.
