Description

Technical Field

[0001] The utility model belongs to the technical field of condensate recovery, in particular to a steam condensate recovery and utilization device. Background Art

[0002] Matter has three states: gas, liquid and solid. Steam is the gaseous state of water. It exists at high temperatures. When the temperature drops, the gas turns into liquid. This process is called "condensation". The liquid water transformed from gaseous steam is called "steam condensate". In the synthetic ammonia industry, a large amount of high-temperature steam is produced, and the heat demand at the production site is limited, so it is necessary to recycle this part of the high-temperature steam and recycle the steam condensate produced during the period.

[0003] At present, in industrial production, the high-temperature steam is usually used for heat exchange with production raw water to achieve heating of the production raw water and cooling of the steam, so that the high-temperature steam is converted into steam condensate, and the steam condensate is filtered and recycled for reuse. However, after the existing filter box has been used for a period of time, the filter screen needs to be inspected and replaced, and the filter screen is usually fixed in the filter box with multiple sets of bolts. The filter box needs to be disassembled first, and then the filter screen is disassembled by bolts, which is not convenient for the inspection and replacement of the filter screen and increases the labor intensity of the staff. For this reason, we propose a steam condensate recycling device. Utility Model Content
