Abstract

The invention discloses a waste water heat energy utilization method applicable to the viscose staple fiber industry. The waste water heat energy utilization method applicable to the viscose staple fiber industry comprises processes of performing heat exchange and recycling on waste hot water during viscose staple fiber production, wherein the waste hot water comprises plasticizing tank overflow water; the processes comprise utilizing the plasticizing tank overflow water to perform step-by-step heat exchange sequentially on plasticizing tank make-up water, desulfurizing liquid and packaged cooling water, the packaged cooling water is conveyed to a cutting machine after heat exchange is performed, and then utilized by a refiner to obtain green cut water, and the green cut water returns to the cutting machine or is conveyed to a plasticizing tank water supplementing tank to serve as plasticizing tank supplement water. The waste water heat energy utilization method applicable to the viscose staple fiber industry achieves comprehensive recycling and utilization of various types of waste hot water and meanwhile achieves heat exchange treatment on specific mediums requiring heating during the viscose staple fiber production, thereby making full use of waste heat of the waste hot water, promoting energy conservation and consumption reduction for enterprises on the basis of existing process waste water treatment and under the premise of no flow losses, and obtaining high social benefits and economic benefits.

Description

technical field

[0001] The invention relates to a waste water thermal energy utilization method suitable for the viscose staple fiber industry, specifically relates to a waste water comprehensive utilization process for the purpose of energy saving and consumption reduction in the viscose staple fiber production process, and belongs to the field of viscose staple fiber production. Background technique

[0002] "Energy consumption" is an important index to evaluate the comprehensive competitiveness of an enterprise in today's era. Every enterprise regards "energy saving and consumption reduction" as the foundation of its own survival, and reduces costs bit by bit, and realizes energy saving with the best management and technology. benefit maximization. Taking the production of viscose staple fiber as an example, a large amount of waste hot water will be discharged during the production process. If it is directly discharged or simply exchanged for heat recovery, a large amount...
