Energy-saving recovery device and energy-saving recovery method for zinc oxide product

Abstract

The invention discloses an energy-saving recovery device and an energy-saving recovery method for a zinc oxide product. The energy-saving recovery device is characterized by comprising a primary cold chamber, a secondary cold chamber and a cloth-bag collecting chamber which are sequentially connected, wherein the primary cold chamber is connected with a steam recovery chamber; an air inlet passage is arranged at the front part of the primary cold chamber; membrane wall heat exchange tube plates are arranged on the four sides of the air inlet passage along the wall; a plurality of rows of heat exchange tube bundles and an ultrasonic generator are arranged at the middle rear part of the primary cold chamber; a plurality of groups of heat exchange channels are arranged in the secondary cold chamber; each group of heat exchange channels is composed of an upper heat exchange channel and a lower heat exchange channel; upper, middle and lower plug boards are arranged on the front and rear sides of the first group of heat exchange channels; a clapboard is arranged on the front side of the second group of heat exchange channels; an inclined clapboard is arranged between the lower plug board on the rear side of the first group of heat exchange channels and the separator; a plurality of ultrasonic generators are arranged on the sidewall of the air inlet passage. The energy-saving recovery device is simple in structure, energy-saving and environmentally-friendly; as a result, the product yield, high heat recovery rate and continuous stability of production can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of zinc oxide production, and more specifically relates to a high-efficiency energy-saving recovery device and method for zinc oxide high-temperature products. Background technique [0002] Zinc oxide (ZnO) is a commonly used chemical additive, widely used in plastics, silicate products, synthetic rubber, lubricants, paint coatings, ointments, adhesives, food, batteries, flame retardants and other products making. Zinc oxide has a large energy band gap and exciton binding energy, high transparency, and excellent room temperature light-emitting performance. It is used in liquid crystal displays, thin-film transistors, and light-emitting diodes in the semiconductor field. In addition, microparticles of zinc oxide, as a nanomaterial, have also begun to play a role in related fields. my country produces more than 105 tons of zinc oxide for industrial use every year, and there are three main production methods....
