Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of gas-liquid separation, and particularly relates to a gas-liquid separation dewatering device. BACKGROUND

[0002] In the production process of ammonium nitrate fluidized bed products, one stream of air is needed to dry the products, and the required air needs to be treated by dewatering, and the treatment device is an air cooling-heating device, which changes the air from a saturated state to an unsaturated state by the method of cooling first and then heating, so as to become dry air. Specifically, the air first enters an air filter to coarsely filter the cotton and dust impurities in the air, and then the temperature of the air is reduced to 10.5 DEG C by a tube-type ammonia cooler, and the cold air (10.5 DEG C) carrying a large amount of condensate after cooling enters a baffle-type gas-liquid separation device to separate the gas and the liquid, and the clean gas after gas-liquid separation enters a steam heating device to increase the temperature of the air to 23 DEG C, and the heated air enters the fluidized bed after passing through an induced draft fan to cool and dry the products. However, due to the high humidity of the air, the humidity is about 100% in severe cases. The separation effect of the system gas-liquid separation device is not good, and the water content of the products increases after the heated air enters the fluidized bed, the cooling efficiency is reduced, the products are caked, and the product quality is affected. Therefore, in order to meet the requirements of product quality and improve the market competitiveness of the products, it is necessary to completely remove a large amount of condensate in the air after cooling.

[0003] The saturated wet air carries a large amount of condensate (about 6257.69 kg / h) after passing through the tube-type ammonia cooler, and the condensate is mainly formed by condensation and inertial collision to form micron-sized liquid droplets with small particle size. The traditional flat-plate baffle mist eliminator is suitable for a gas-liquid coarse separation system with high flow rate, large liquid carrying amount and large liquid droplet particle size, and the separation and removal effect of micron-sized liquid droplets is poor.

[0004] In order to overcome the shortcomings of the prior art, the utility model provides a high-efficiency combined gas-liquid separation dewatering device, which effectively removes the moisture in the air, thereby reducing the wear and tear and scaling of the compressor, improving the stability and service life of the compressor, reducing the maintenance frequency and cost of the compressor, and improving the quality of subsequent products.
