Embodiment 1
[0049] A large particle ammonium sulfate product such as figure 1 As shown, its production process includes the following steps:
[0050] S1. First add sulfuric acid, ammonia and the washing liquid from the gas-liquid separator into the tubular reactor for neutralization reaction. The slurry formed after the reaction is sprayed into the granulator, and sprayed into the solid material bed through the nozzle Granulation binder, and then spray ammonia for granulation to form solid wet material and granulation tail gas, wherein the granulation temperature is 80°C, and the water content of the solid wet material at the outlet of the granulator is 3%;
[0051] S2. The tail gas after granulation enters the gas-liquid separator and the washing liquid from the circulating pump of the gas-liquid separator is fully atomized and mixed in the Venturi injector. The gas-liquid mixture enters the gas-liquid separator for separation, and the washing liquid passes through the circulating pump a...

[0057] A large particle ammonium sulfate product such as figure 1 As shown, its production process includes the following steps:
[0058] S1. First add sulfuric acid, ammonia and the washing liquid from the gas-liquid separator into the tubular reactor for neutralization reaction. The slurry formed after the reaction is sprayed into the granulator, and sprayed into the solid material bed through the nozzle Granulation binder, and then spray ammonia for granulation to form solid wet material and granulation tail gas, wherein the granulation temperature is 90°C, and the water content of the solid wet material at the outlet of the granulator is 4%;
[0059] S2. The tail gas after granulation enters the gas-liquid separator and the washing liquid from the circulating pump of the gas-liquid separator is fully atomized and mixed in the Venturi injector. The gas-liquid mixture enters the gas-liquid separator for separation, and the washing liquid passes through the circulating pump a...
Embodiment 3
[0065] A large particle ammonium sulfate product such as figure 1 As shown, its production process includes the following steps:
[0066] S1. First add sulfuric acid, ammonia and the washing liquid from the gas-liquid separator into the tubular reactor for neutralization reaction. The slurry formed after the reaction is sprayed into the granulator, and sprayed into the solid material bed through the nozzle Granulation binder, and then spray ammonia for granulation to form solid wet material and granulation tail gas, wherein the granulation temperature is 110°C, and the water content of solid wet material at the outlet of the granulator is 5%;
[0067] S2. The tail gas after granulation enters the gas-liquid separator and the washing liquid from the circulating pump of the gas-liquid separator is fully atomized and mixed in the Venturi injector. The gas-liquid mixture enters the gas-liquid separator for separation, and the washing liquid passes through the circulating pump and ...
