A hot-dip galvanized air curtain side suction zinc fume environmental protection device

Abstract

The invention discloses a hot zinc plating zinc smoke air curtain and side-suction environmental protection apparatus, and belongs to the technical field of hot zinc plating flue gas recovery environmental protection. The hot zinc plating zinc smoke air curtain and side-suction environmental protection apparatus comprises a zinc pot, wherein a thermal insulation material is arranged surrounding the zinc pot, a furnace bottom observation chamber is arranged on the outer periphery of the thermal insulation material, both sides of the zinc pot edge are respectively provided with a separation plate, the separation plate is mainly used for preventing the generation of splashing when a product enters a zinc liquid, an air port is arranged above the separation plate, and the air port blows an obliquely downward air flow. According to the present invention, when a product enters the zinc liquid, a lot of zinc smoke can be produced, the air flow forms the air curtain to isolate the zinc smoke, the inward and downward swirl is generated on the inner side in the zinc pot to effectively block the rising zinc smoke, the platform is arranged above the air port so as to make the work conveniently perform necessary labor, the air suction port is arranged on the lower side of the separation plate and close to the pot edge position, and the negative pressure air flow exist in the air suction port, such that the zinc smoke is controlled at the position close to the zinc surface and is rapidly sucked out and treated under the double effects of the air curtain and the side suction, and the harm on the staff and the environment due to the spreading into the workshop can be prevented.

Description

technical field [0001] The invention relates to the technical field of hot-dip galvanizing zinc smoke treatment environmental protection, in particular to a hot-dip galvanizing smoke dust environmental protection device on an air curtain side. Background technique [0002] Compared with other industries, hot-dip galvanizing will produce more dust, acid and alkaline substances in the process of a large number of pretreatment and galvanizing, which will cause harm to the surrounding environment and the health of workers. Considerable impact, galvanizing flue gas is mainly produced in the galvanizing and pickling process of hot-dip galvanizing, in which the pollutants in the flue gas generated in the galvanizing process are mainly particles containing a large amount of zinc and zinc oxide, galvanizing The characteristics of the flue gas in the process are intermittent and instantaneous burst emission. [0003] At present, the treatment method of zinc fume is to install a smoki...

AI Technical Summary

Problems solved by technology

[0003] At present, the treatment method of zinc fume is to install a smoking port around the zinc pot, but this method can only absorb the zinc fume near the smoking port, and other locations, especially the center of the zinc pot, due to the amount of zinc fume produced there The largest, and this position is often the farthest from the smoking port, the effect of absorbing zinc fume is very poor, which has a great impact on the working environment of the workshop
