Abstract

The invention discloses an alcohol-water separation recycling device of fischer-tropsch synthesis water, and belongs to the technical fields of environmental protection and recycling. The alcohol-water separation recycling device comprises a pretreatment system, a separation system, a concentration system, a dehydration system and a recycle water system, wherein the pretreatment system comprises a raw material tank, a first feeding pump, neutralization reaction equipment, a coagulation air floatation device, a second feeding pump, a precision filter, a membrane filter and a first middle material liquid tank, which are sequentially connected; the separation system comprises a third feeding pump; a feeding hole of the third feeding pump is connected with the first middle material liquid tank; a discharge hole is connected with the feeding hole of alcohol-penetrating membrane equipment after being connected with a first heat exchanger; a penetrating fluid discharge hole of the alcohol-penetrating membrane equipment is connected with a second heat exchanger; and the second heat exchanger is respectively connected with a first vacuum pump, a liquid-liquid separator and the like. By adopting the alcohol-water separation recycling device, available resources which are discharged as wastewater in the past are effectively recovered by using low energy consumption; a disadvantage is converted into an advantage; resources and energy sources are saved; and the target of recycling to create profit is also achieved.

Description

technical field [0001] The invention relates to an alcohol-water separation and recovery device for Fischer-Tropsch synthetic water, which belongs to the technical field of environmental protection and resource utilization. Background technique [0002] With the rapid development of the economy, the requirements for environmental protection are getting higher and higher, and the available resources are getting less and less. In the process of industrial production, especially in petrochemical, fine chemical and other industries, a large number of industrial by-products are produced, and some by-products have great recycling value. If these waste water and waste liquid are not properly treated and discharged directly, it will have a bad impact on the surrounding environment and affect human health. At the same time, the waste or discharge of such valuable organic solvents also causes a serious waste of resources. [0003] The gas-to-liquid (GTL) technology of producing liqu...
