Description

Technical Field

[0001] The utility model relates to the technical field of condensed water waste heat recycling, in particular to a steam condensed water waste heat recycling device with temperature and pressure regulating functions. Background Art

[0002] During starch production, boiler-generated steam is often used to heat certain equipment, such as the starch raw materials and chemicals in vacuum reactors. Since starch plants use a large amount of raw steam, measured in tons, heating these equipment with the steam theoretically produces several tons of condensate. This condensate is relatively high, at approximately 90°C, and contains significant heat energy. If discharged without proper treatment and utilization, it would waste significant amounts of heat energy and water resources.

[0003] According to a steam condensate waste heat utilization device disclosed on the patent website (authorization announcement number: CN 216482367U), "a steam condensate waste heat utilization device is described, including a shell, a heat exchange unit is provided in the shell, a solid filter unit is provided in the shell, and the solid filter unit is detachably connected to the shell. The utility model realizes the filtration of solids in the liquid to be treated by arranging a filter screen, and realizes the disassembly of the filter screen by arranging a filter screen flange and a shell flange, which facilitates the cleaning of the filtered solids. By arranging the heat exchange unit, further utilization of heat is realized. The utility model solves the problem that the existing heat exchanger is not convenient to clean the dirt inside, which leads to low efficiency of the heat exchanger after long-term use and even causes blockage of the heat exchanger."

During the long-term use, due to the high temperature of the condensed water added to the heat exchange device, pressure changes are likely to occur. At the same time, the device cannot filter the condensed water and cannot adjust the flow rate of the condensed water during the heat exchange process. Therefore, it is necessary to improve a steam condensate waste heat recycling device with temperature and pressure regulation function to solve the above problems. Utility Model Content
