Embodiment Construction

[0011] The device will be further described below in conjunction with the accompanying drawings.

[0012] The present invention is composed of the heating system (D) of the concentration tank, the steam saturated packed tower (B) and the superheated steam supply system (C) and the cooling water supply system (A) used in conjunction with it, such as figure 1 As shown; this device realizes superheated steam recovery and waste heat utilization technology, and applies steam phase change technology to actual industrial production. The superheated steam generated in the industrial production of nylon 66 is recovered by a steam saturation tower, converted into saturated steam and utilized , form a heating system that uses saturated steam to heat the concentration tank (4), replace the biphenyl heating system in the original concentration tank heating system (D), and ensure that the temperature of the nylon 66 salt solution in the concentration tank (4) is maintained at the optimum eva...

Abstract

The present invention discloses a superheated steam recycling and waste heat utilizing apparatus. The apparatus consists of a steam saturation packing column, a superheated steam supply system, a cooling water supply system and a concentration tank heating system. The apparatus recycles and utilizes the superheated steam produced in the nylon 66 production to replace a biphenyl heating mode in the concentration tank heating system of the primary production process; an outlet of the superheated steam supply system is connected to a superheated stream inlet of the steam saturation packing column; an outlet of the cooling water supply system is connected to a cooling water inlet of the steam saturation packing column; a saturated water outlet of the steam saturation packing column is connected to a central pool, and a saturated steam outlet of the steam saturation packing column is connected to an inlet of the concentration tank heating system; and an outlet of the concentration tank heating system is connected to the central pool by virtue of a pipe.

Description

technical field [0001] The invention relates to a superheated steam recovery and waste heat utilization device, which belongs to the technical field of industrial energy saving, in particular to the field of industrial waste gas recovery and waste heat utilization. Background technique [0002] The polymerization reactor in the nylon 66 production process will discharge a large amount of superheated steam during production, and the oligomers, hexamethylenediamine and adipic acid contained in it are toxic to the human body; The treatment function is limited, and the superheated steam is directly discharged into the atmosphere without treatment, which not only causes serious environmental pollution problems, but also causes huge energy waste; with the continuous expansion of the influence of the concept of sustainable development, the concept of low-carbon environmental protection has been deeply rooted in the hearts of the people, and the environment Pollution and industrial ...
