Abstract
Description
Technical Field
[0001] This utility model relates to the field of methanol evaporator technology, and in particular to a methanol evaporator that can utilize waste heat. Background Technology
[0002] Methanol is one of the main raw materials for the production of formaldehyde. In the formaldehyde production system, methanol is evaporated from liquid to gas, and then used as one of the gases in the formaldehyde production process. It is added to other mixed gases to finally produce formaldehyde.
[0003] Currently, existing methanol evaporators generally have a prominent problem: after the methanol evaporation process is completed, a considerable amount of heat remains unused, resulting in a relatively low energy utilization rate. This increases production and operating costs and does not meet the current overall requirements for efficient energy utilization and reduced energy waste in industrial production processes.
