Description

Technical Field

[0001] The utility model relates to the technical field of heat exchange, in particular to a steam thermal oil heat exchanger. Background Art

[0002] During the production process of hazardous waste lines, the flue gas cooler is a set of equipment for cooling the flue gas. Generally, the steam generated in this process is discharged into the atmosphere through a muffler or condensed and recycled through a condenser.

[0003] The steam generated during the production process is basically discharged through the silencer and can only be used for heating and heat exchange in office buildings in winter. As the production line operates throughout the year, a large amount of steam is discharged, which invisibly wastes a lot of heat energy and is not fully utilized. It also wastes a lot of natural gas costs.

[0004] The three-phase separation workshop requires a large amount of heat source to heat the raw materials. The existing equipment for heating the raw materials in the three-phase separation workshop is a thermal oil furnace. Natural gas needs to be burned to heat the thermal oil, and then the thermal oil is used to exchange heat with the raw materials to reach the raw material production temperature. This process costs a lot of gas.

[0005] In order to make full use of the thermal energy of self-produced steam, reduce the waste of self-produced steam in the hazardous waste incineration line and the gas cost of the thermal oil furnace, we proposed a steam thermal oil heat exchanger. Utility Model Content
