Technical Field

[0001] The utility model relates to the technical field of condensate recovery, in particular to a recovery device for synthetic ammonia condensate. Background Art

[0002] The process of industrially preparing ammonia includes multiple steps. When ammonia vapor is generated, a small amount of water vapor is generally present in the vapor. Therefore, in order to purify the ammonia, the water vapor needs to be condensed and recovered. Although the existing condenser can cool down and condense the water vapor by circulating water, it is difficult to achieve a good effect when used for a mixture of high-temperature ammonia vapor and water vapor. A small amount of water vapor is often discharged along with the ammonia vapor, making the ammonia content impure.

The synthetic ammonia condensate recovery device extracts circulating water from the bottom circulating water tank through the input end of the water pump using the water inlet pipe, and the output end of the water pump and the water outlet pipe input the water flow into the top circulating water tank, and the circulating water flows into the condensate pipe, so that the circulating water can circulate, reducing the consumption of water resources, and squeezing is generated by the adsorption layer and the fixed template, so that the condensed water in the adsorption layer drops on the upper surface of the bottom inclined block in the condensate tank, and the water drops flow to the right and flow from the guide pipe to the circulating water tank for collection, so as to facilitate the use of the recovered water;

[0004] The above-mentioned prior art solution has the following defects: the connecting rod is driven to slide in the guide groove by the hydraulic cylinder, but when the airflow enters the condensation box, part of the airflow will float out of the condensation box through the guide groove, thereby reducing the recovery effect. In view of the above situation, technical innovation is carried out on the basis of the existing recovery device of synthetic ammonia condensate. Utility Model Content
