Nitrogen sealing system for insulating box of cracked gas electric filter

Abstract

The utility model discloses a nitrogen sealing system for an insulation box of a cracked gas electric filter. A knob insulator is arranged at the middle top in a knob insulator supporting box, an insulating box is fixed on the upper portion of the knob insulator supporting box, the knob insulator enables the knob insulator supporting box and the insulating box to be two vertically-isolated box chambers through a sealing device, a nitrogen inlet valve is arranged at the lower left end of the insulating box, and a nitrogen outlet valve is arranged in the middle of the top of the insulating box. Low-pressure nitrogen enters the insulation box through the nitrogen inlet valve and then is discharged through the nitrogen outlet valve. According to the utility model, the nitrogen sealing device for the insulation box is additionally arranged between the knob insulator and the knob insulator supporting box, so that flammable and explosive gases are prevented from entering the insulation box, the safety production is ensured, and the production efficiency is improved.

Description

Technical field:

[0001] The utility model relates to a nitrogen sealing system for an insulation box of a cracked gas electric filter. Background technology:

[0002] The cracker electric filter is filled with flammable and explosive dangerous nitrogen gas, which places extremely strict requirements on the sealing of the equipment. In addition, the seal between the porcelain column and the porcelain column support box is prone to failure due to long-term operation or other reasons, resulting in leakage, which is very likely to cause safety accidents and affect production efficiency. Utility model content:

[0003] The utility model provides a nitrogen sealing system for a cracked gas electric filter insulation box, which adds an insulation box nitrogen sealing system between a porcelain column and a porcelain column supporting box to prevent flammable and explosive gases from entering the insulation box, ensure safe production, and improve production efficiency.

[0004] The technical scheme adopted by the utility model to achieve the above-mentioned purpose is as follows: the porcelain column of the nitrogen sealing system of the cracking gas electric filter insulation box is arranged at the top in the middle of the porcelain column support box, the insulation box is fixed on the upper part of the porcelain column support box, the porcelain column is used to isolate the porcelain column support box and the insulation box from the upper and lower parts into two box chambers through a sealing device, the nitrogen inlet valve is arranged at the lower left end of the insulation box, the nitrogen outlet valve is arranged in the middle of the top of the insulation box, and the low-pressure nitrogen enters the insulation box through the nitrogen inlet valve and is discharged through the nitrogen outlet valve.

[0005] The beneficial effect of the utility model is that since the utility model adds an insulating box nitrogen sealing device between the porcelain column and the porcelain column supporting box, it is prevented that flammable and explosive gases will not enter the insulating box, thereby ensuring safe production and improving production efficiency.
