Wet type static solid strip-shaped anode dust collecting plate

Abstract

The invention provides a wet type static solid strip-shaped anode dust collecting plate. The strip-shaped anode dust collecting plate is characterized in that a pole plate is composed of solid strip-shaped bodies, the strip-shaped bodies are horizontally arranged and are woven through ropes or connected by a single layer of plywood, necessary gaps are formed among the strip-shaped bodies, and the sizes of the gaps are determined by liquid holdup, surface tension, liquid film thickness and solid-liquid characteristics. The strip-shaped anode dust collecting plate provided by the invention has the advantages that a horizontal water film is uniform by virtue of the capillary phenomena of the gaps; the gaps internally contain liquid to increase the liquid holdup of the pole plate so as to keep a liquid film stable; the gaps can penetrate through the two sides of the pole plate and can transmit the pressure fluctuation of airflow on the two sides of the pole plate, then the water film is driven to vibrate, and thus dust is prevented from precipitating on the pole plate.

Description

1. Technical field [0001] The invention relates to an anode plate for wet electrostatic dust removal / fog removal, which belongs to the technical field of air pollution control. 2. Background technology [0002] The high-efficiency performance of wet electrostatic mainly depends on the uniform water film on the surface of the anode plate, which can clean the particles collected on the surface of the anode plate, and avoid the secondary carryover caused by mechanical vibrating dust removal in traditional dry electrostatic technology. However, according to the principle of energy minimization, when water flows through the surface of a traditional vertical solid anode, it is easy to form a channel flow, and the formation of a relatively uniform water film is generally achieved by spraying or distributing water on the upper part of the plate to ensure that the water film continuity and uniformity. In order to reduce water consumption or reduce circulating water and increase the ...

AI Technical Summary

Problems solved by technology

In order to reduce water consumption or reduce circulating water and increase the uniformity of water film, some inventions in the industry have made efforts and contributions: Chinese patent 201020106426.2 proposes a strip plate composed of many narrow vertical bars, and the water film It is fixed inside the vertical bar, but the capillary phenomenon of the vertical bar slit is consistent with gravity, the liquid holding capacity of the plate is small, and there is still the possibility of "dry spots" on the surface of the plate due to uneven surface water film; Chinese patent 201120483473.3 proposes a A corrugated dust collection plate used to increase the dust collection area also has the influence of continuous solid surface tension, which cannot ensure uniform water film, and cannot avoid "dry spots" with a small amount of water; Chinese patent 201310077865.3 proposes a method by means of The horizontal striped dust collection plate with grooves for lateral flow diversion, but the air in the grooves will block the lateral diffusion of the liquid phase at the same time, and it is difficult to produce a uniform water film on the surface of the anode plate

The existing patents do not pass a specific structure in the process of forming the water film, and propose an external force that causes the liquid film to vibrate, so that there is a risk of particles adhering to the polar plate inside the static liquid film and causing fouling

In addition, the liquid holding capacity of the plates involved in the existing patents is relatively small, and a large spray volume must be relied on to maintain a continuous water film
