Embodiment Construction

[0016] Attached below figure 1 and specific embodiments, further explain the present invention in detail. It should be noted that the system of the present invention is also applicable to waste heat recovery in other industries, such as petrochemical, daily chemical, textile printing and dyeing, food, medicine, building materials and other industries.

[0017] Such as figure 1 As shown, a fatty acid production process waste heat recovery system includes flash tanks 1-2, steam jet heat pumps 3-5, and high-temperature condensate pumps 6-7.

[0018] The steam condensate inlet of the flash tank 1 is connected to the high-temperature steam condensate discharge outlet of the fatty acid production device, the flash steam outlet of the steam tank 1 is connected to the low-pressure steam port of the steam jet heat pump 3 through a check valve, and the mixed steam outlet of the steam jet heat pump 3 passes through the steam The pipe network 1 is connected to the steam-using equipment,...

Abstract

The invention provides a recycling system for waste heat generated in a fatty acid production process. The recycling system comprises flash tanks, steam-jet heat pumps, high temperature condensate water pumps, and pipelines, pipe fittings and valves, which are used for connecting the flash tanks, the steam-jet heat pumps and the high temperature condensate water pumps. Double flash evaporation is conducted on high temperature steam condensate water in the flash tanks so as to generate low pressure secondary flash steam, high pressure steam is used as driving steam, and after the pressure of the low pressure secondary flash steam is increased at one step or at two steps by the steam-jet heat pumps to reach the pressure in the fatty acid production process, the low pressure secondary flash steam is used in a workshop. The recycling system is concise in structure, stable and reliable, efficient and energy-saving, stepwise utilization of the flash steam formed after the high temperature steam condensate water is flashed is realized, the environment is improved, the production cost is reduced, and the economic benefits are increased.

Description

technical field [0001] The invention relates to the technical field of an energy-saving and environment-friendly system for a fatty acid production process, in particular to a waste heat recovery and utilization system for a fatty acid production process. Background technique [0002] Fatty acid is a class of compounds composed of three elements, C, H, and O. Its main sources are animal oil, vegetable oil, liquid rosin, and paraffin oxidation synthesis. [0003] At present, my country's fatty acid production process mainly includes: alkali deep saponification-acidification method, atmospheric pressure catalytic hydrolysis method, pressurized (medium and high pressure) non-catalytic hydrolysis method, etc. These processes will generate a large amount of steam condensed water in the fatty acid production process, and the condensed water will be discharged directly after passing through the steam trap, and the secondary steam generated during the discharge process will not be r...
