A low energy consumption insulator box and electric tar capture device

Abstract

The invention relates to a low-energy-consumption insulator box and an electric tar-catching device. The insulator box adopts a combining mode of four types of devices, namely a silica-gel insulator section, a vertical type ceramic insulator section, a labyrinth type ionization section and a cover type blocking ionization section; a suspending point is arranged at the top part of an inner cavity of the silica-gel insulator section, silica-gel insulators connected in series are suspended on the suspending point, and the lower ends of the silica-gel insulators extend downwards and penetrate through pulling rods of inner cavities of the vertical type ceramic insulator section, the labyrinth type ionization section and the cover type blocking ionization section. The low-energy-consumption insulator box and the electric tar-catching device have the advantages that the electric-catching insulation breakdown caused by aggregation of steam, impurities and the like in an electric-catching insulation box is avoided fundamentally, further continuous heating and nitrogen protection in electric-catching operation are further eliminated; the consumption of auxiliary energy such as the steam, power and nitrogen is greatly and fundamentally reduced, the use cost is reduced, the energy consumption can be reduced to below 1% of the prior art; simultaneously, by improvement on corona wires, the use period of electric catching is prolonged; the promotion value and the economic benefit are good.

Description

technical field [0001] The invention provides a low energy consumption and long life electric capture device which can be widely used in the coal coking industry to ionize and capture impurities, tar and liquid droplets in the gas in the gas treatment process, and the device used in the insulator box. Background technique [0002] In the process of gas treatment in the coal chemical industry, electric tar traps are usually used to perform high-pressure ionization on impurities, tar, liquid droplets, etc. in the gas to purify the gas. [0003] However, there are two problems in the currently used electric tar catcher, which leads to high auxiliary energy consumption of the electric tar catcher. The auxiliary energy consumption mainly comes from the auxiliary energy consumption of the insulating box, and the service life cycle of the electric tar catcher Short is mainly caused by high voltage discharge breakdown. [0004] Since the electric tar catcher is a high-voltage devi...

Problems solved by technology

One is to set up a steam jacket to heat the insulation box to prevent the insulator from condensation and conduct electricity; the other is to pass nitrogen gas into the interior for gas protection to prevent the accumulation of impurities and conduct electricity. However, these two methods consume a lot of energy and are also auxiliary energy consumption. main source of

[0006] The second factor that affects the service life of the electric tar catcher is the break of the corona wire. During the use of the electric catch, the electric catch will be grounded and shut down due to various reasons, and the main reason is the break of the corona wire. Therefore, how to ensure the long life of the corona wire is directly related to the service life of the electric trap.
