Embodiment Construction

[0015] The invention discloses a galvanized flue gas recovery and utilization system, which ensures the maximum utilization of the waste heat of the flue gas, improves the utilization rate of heat, and is energy-saving and environment-friendly. Under the premise of meeting the production needs, the galvanized pot is guaranteed to be heated evenly, the burning loss of the pot body is reduced, and the service life of the galvanized pot is prolonged. The effective use of waste heat can effectively reduce the labor intensity of workers, reduce energy consumption, and reduce production costs.

[0016] The technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary s...

Abstract

A galvanization smoke recycling system comprises a hanging piece device, a pickler, a washing device, a plating assisting device, a heating device, a drying device and a passivation device which are sequentially arranged. The pickler is connected with an acid mist collecting and treating device. The washing device is connected with a waste water collecting and treating device. The plating assisting device comprises a plating assisting trough used for containing plating assisting liquid. The plating assisting trough is connected with a plating assisting liquid treatment device. The heating device comprises a plating assisting liquid heating device body and a galvanizing trough heating device. The drying device is a drying oven provided with a heat exchanger. The pickler is a stepping type automatic pickling device. According to the galvanization smoke recycling system, it is guaranteed that smoke waste heat is utilized to the maximum degree, the heat utilization rate is increased, and energy saving and environment friendliness are achieved. On the premise that the production need is met, uniform heating of a galvanized pot is guaranteed, burning losses of a pot body are reduced, and the service life of the galvanized pot is prolonged. By means of effective utilization of waste heat, the labor intensity of workers can be effectively relieved, energy consumption is reduced, and the production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of hot-dip galvanizing, in particular to a system for recovering and utilizing waste heat of galvanizing flue gas. Background technique [0002] Galvanizing refers to a surface treatment technology that coats a layer of zinc on the surface of metal, alloy or other materials for aesthetics and anti-rust effects. The main method used is hot-dip galvanizing. Hot-dip galvanizing is a process technology in which steel, stainless steel, cast iron and other metals are immersed in molten liquid metal or alloy to obtain a coating. Hot-dip galvanizing is the most widely used steel surface treatment method with the best cost performance in the world today. [0003] For hot-dip galvanizing pre-treatment and post-treatment heating of hot water and various chemical solutions, most manufacturers use steam or electric heating, which not only increases energy consumption, but also requires a certain increase in investment. ...
