Problems solved by technology

[0004] When the wet electrostatic precipitator is used under negative pressure conditions, the above method and structure can ensure that there will be no dust accumulation and creepage inside the ceramic bottle; but when the wet electrostatic precipitator is under positive pressure conditions, The above method and structure, due to the swirling flow in the flow field, may cause the smoke to flow back into the ceramic bottle, or even into the insulation barrel, and then pollute the ceramic bottle and the insulation barrel, causing corresponding safety accidents, and there are potential safety hazards

Abstract

The invention belongs to the field of metallurgical and chemical equipment, and particularly discloses a nitrogen rotational flow sealing heat preservation barrel for a wet-type electric precipitator, which comprises a barrel body, an insulator communicated with the wet-type electric precipitator is arranged in the barrel body, and a nitrogen rotational flow sealing structure is arranged on the barrel body. The nitrogen rotational flow sealing structure comprises a nitrogen supplementing pipe, a nitrogen drainage pipe and a nitrogen storage cavity communicated with the nitrogen drainage pipe, the barrel body comprises a barrel body upper portion and a barrel body base, and a plurality of drainage holes allowing nitrogen to flow into the barrel body base and forming rotational flow in the barrel body base are formed in the side wall of the nitrogen storage cavity. And the rotational flow flows towards the wet-type electric dust remover. The part where nitrogen is introduced into the barrel body is improved, the nitrogen flowing state is optimized, a nitrogen curtain wall is formed in the barrel body, an insulator is isolated from the wet-type electric dust remover, and smoke in the wet-type electric dust remover is prevented from reversely flowing into the insulator, so that it is guaranteed that the insulator is not polluted, the insulation performance of the insulator is guaranteed, and safety accidents are avoided; potential safety hazards are eliminated.

Description

technical field [0001] The invention relates to the fields of metallurgy and chemical equipment, in particular to a nitrogen cyclone sealed thermal insulation barrel for a wet electrostatic precipitator. Background technique [0002] In the process of metallurgical and chemical production, the generated flue gas usually contains a large amount of dust, water vapor or corrosive gas, such as blast furnace flue gas. In order to meet the increasingly stringent environmental protection requirements, the flue gas must be treated accordingly before it is discharged to make it meet the emission standard. [0003] At present, wet electrostatic precipitators are often used in engineering to efficiently remove droplets, dust, etc. in flue gas to achieve deep purification of flue gas. In the wet electrostatic precipitator, since the corona electrode system of the electrostatic precipitator is a high-voltage charged body, its suspension support device must be well insulated from the gro...
