Problems solved by technology

[0002] The existing technical scheme adopts the no-heat pressure difference regeneration method in the gas regeneration process. The regeneration tower uses the dry air of the working tower to blow from top to bottom, and uses the dry air to regenerate the molecular sieve in the adsorption tower. The regeneration process requires a large amount of regeneration gas

Abstract

The invention discloses a full-automatic drying, purifying and pressure reducing device applied to an SF6 gas transmission system. The device comprises a controller, a purification and pressure reducing system, an online monitoring system for monitoring the purity of the purification and pressure reducing system, and an automatic gas regeneration system for recovering gas in the purification and pressure reducing system, wherein the purification and pressure reducing system comprises a pressure reducing system and a drying purification system, the automatic gas regeneration system comprises arecovery system, a heating system and a vacuum purification system, the on-line monitoring system, the pressure reducing system, the heating system, the recovery system, the heating system and the vacuum purification system are all installed on the drying purification system, and a controller is electrically connected with the purification and pressure reducing system, the online monitoring systemand the automatic gas regeneration system. Through a brand-new integration and control mode, online monitoring of various indexes of SF6 gas in an SF6 gas transmission system is realized, automatic switching and vacuum heating regeneration of a system AB tower are controlled through online monitoring results, and in a regeneration process, zero emission of SF6 gas is achieved, and the environmentis protected.

Description

technical field [0001] The invention relates to a fully automatic drying, purifying and decompressing device applied to an SF6 gas transmission system, and belongs to the technical field of gas fully automatic drying, purifying and decompressing. Background technique [0002] The existing technical scheme adopts the no-heat pressure difference regeneration method in the gas regeneration process. The regeneration tower uses the dry air of the working tower to blow from top to bottom, and uses the dry air to regenerate the molecular sieve in the adsorption tower. The regeneration process requires a large amount of regeneration gas. The principle of the adsorption dryer used in the dry air system is as follows: Figure 7 As shown, according to the design of the compressed air system, although the drying and purification of the gas can also be realized, the design concept is completely different from the requirements of the SF6 gas. [0003] As an insulating medium for high-vol...
