An ESP dust hopper overhaul process

Abstract

An maintenance process for the ash hopper of electrostatic precipitator, which reversely adjusts the routine maintenance procedure of the ash hopper, and through reverse construction, solves the problem that the construction materials are transported inside the ash hopper, without the cooperation of a crane, without the need for a full house of scaffolding, which greatly saves construction costs and The construction safety is ensured, and the construction period is shortened. The interior of the ash hopper is a limited space. This application rationally optimizes the sequence and method of repairing the ash hopper wall panels, and adopts a cycle-alternating method, from bottom to top, from layer to surface, to avoid wall Slab repair and scaffold erection interfere with each other, and save a lot of construction materials and labor. And the innovative use of the aluminum skin mold setting method solves the problem of measuring and blanking the variable cross-section reinforcing ring, simplifies the operation steps, and at the same time ensures the dimensional accuracy. Cultivation must be done, practice must be done well, and the purpose of combining practice and defense.

Description

technical field [0001] The invention relates to the field of maintenance of ash hoppers, in particular to a process for maintenance of an electric dust collector ash hopper. Background technique [0002] Electrostatic precipitator is an important environmental protection equipment of thermal power plant, which is composed of supporting steel structure, inlet and outlet speakers, shell, cathode and anode system, ash hopper, stair platform and other components. [0003] As one of the important components of the electrostatic precipitator, the ash hopper is to collect and store dust for a short time. Dust blocking or fluffing often occurs, resulting in poor ash conveying, reduced dust removal efficiency, electric field short circuit, and damage to electrical components. In severe dust accumulation, it may even cause accidents such as the ash hopper falling off and the electrostatic precipitator collapsing. [0004] In recent years, with the establishment and reconstruction of ...

AI Technical Summary

Problems solved by technology

Often there will be dust blocking or fluffing, which will lead to problems such as poor ash conveying, reduced dust removal efficiency, short circuit in the electric field, damage to electrical components, etc. When serious dust accumulation occurs, it may even cause accidents such as the ash hopper falling off or the electrostatic precipitator collapsing.
