Abstract

The invention provides a preparation method of sodium butyrate granules and a tail gas treatment method of the sodium butyrate granules. The invention relates to the field of preparation of non-antibiotic growth-promoting feed additives. The preparation method mainly comprises the following steps: preparing a sodium butyrate raw material, mixing the components, extruding the mixture into strips, granulating the mixture, and performing shot blasting and drying. The invention also relates to the treatment method for tail gas in preparation of the sodium butyrate granules. The treatment method comprises the following steps: collecting tail gas obtained by spray drying, treating the tail gas through a heat exchanger so as to collect heat in the tail gas, and then treating the cooled tail gas through a two-stage water film scrubber tower so as to obtain clean tail gas; and finally, performing heat exchange through the heat exchanger, and compensating heat for the storage tank through the jacket and discharging the residual clean gas. The preparation method of the sodium butyrate granules is safe, simple, convenient, good in controllability, environment-friendly and reliable.

Description

technical field [0001] The invention relates to the field of preparation of non-antibiotic growth-promoting feed additives, in particular to a preparation method of sodium butyrate granules and a tail gas treatment method thereof. Background technique [0002] With the promulgation and implementation of new feed regulations, the use of antibiotics in feed additives, feed and breeding industries has been completely banned. Sodium butyrate raw powder (feed additive) as an antibiotic substitute has been approved in the feed and breeding industries after years of development, and its usage is increasing. The original powder type sodium butyrate product is a 60-120-mesh powder with a small specific gravity, large volume during transportation, and high transportation costs; during use, it is easy to generate dust, easy to absorb moisture, and has a sour smell of rotten cheese. It is easy to use, and part of the powder will be sucked away by the induced air system during the proce...
