Embodiment 1

[0026] The overall configuration of the electrolyzer cover plate is as follows: figure 1 shown.

[0027] Such as Figure 4 , The electrolytic tank cover plate is divided into three types: A, B, and C. The B plate is the fixed cover plate located at the two ends of the tank, and there are 4 pieces in total; the C plate is the door located in the middle of the two ends of the tank, and it is also 4 pieces; the A plate It is a movable cover plate located on both sides of the tank. The number of A plates in each tank is equal to the number of anode blocks + 2, and the width of A plate is basically equivalent to the anode block + inter-electrode gap. Such as Figure 4 As shown, if 2 sets of anodes are replaced at a time, 3 A-plates at the corresponding positions can be opened; if 1 set of anodes is replaced at a time, 2 A-plates at the corresponding positions can be opened. All A-plates have the same structural size and good interchangeability. The gap between the anode guide r...

Abstract

The invention discloses a novel energy-saving emission-reducing tank cover plate and application thereof. Insertion strip sealing is adopted between two tank cover plates, and the lower portions of the tank cover plates are provided with transverse seams serving as air vents (6). Sealing strips (5) for insertion strip sealing refer to packing aluminum silicate fiber-woven felt strips. The novel energy-saving emission-reducing tank cover plate has the advantages that interchangeability of the tank cover plates can be improved, both energy saving and safety can be achieved, and the tank cover plate can be used for planar tank covers and cabochon tank covers.

Description

technical field [0001] The invention belongs to the technical field of modern prebaked anode aluminum electrolytic cells, and in particular relates to a novel energy-saving and emission-reducing cell cover plate and its application. Background technique [0002] The tank cover is one of the important parts of the modern prebaked anode aluminum electrolytic cell, and its main function is to block harmful fumes and heat from being emitted into the electrolytic workshop. In the past two years, in order to reduce power consumption, many electrolytic aluminum enterprises in China have used waste cloth bags to seal the slot cover gaps and shut down 1-2 smoke exhaust fans in order to improve energy utilization and reduce tank voltage. However, most of the electrolytic aluminum series have poor heat dissipation in the upper part of the electrolytic cell, continuous high temperature of the side steel plate (the side of the furnace is dissolved), and the temperature of the bottom of t...
