Plugging device for thermal power plant boiler body and desulfurization facility cable

Abstract

The invention discloses a plugging device for a thermal power plant boiler body and a desulfurization facility cable, and the device comprises a machine body and a plugging frame; threaded holes are formed in the two sides of the top end of the machine body, bolts are attached to the inner walls of the peripheries of the threaded holes, the plugging frame is installed at the center connecting positions of the bolts and the threaded holes, and supporting frames are fixed to the two sides of the top end of the plugging frame; telescopic bases are symmetrically distributed on the inner wall of the supporting frame, telescopic short rods are installed on the inner walls of the telescopic bases, and spring pieces are arranged in the telescopic short rods. The plugging device is provided with the plugging frame, and the plugging frame and a machine body form a detachable structure through threaded holes and bolts. The plugging frame is installed at the top end of the machine body through threaded connection formed between threaded holes in the two sides and bolts, the connecting strength and stability between the plugging frame and the machine body can be improved as much as possible, the inner wall of the lower end of the plugging frame is attached to the outer wall of the upper end of the machine body, and the sealing performance between the plugging frame and the machine body is guaranteed.

Description

technical field [0001] The invention relates to the technical field of a thermal power plant boiler body and a desulfurization facility cable, in particular to a plugging device for a thermal power plant boiler body and a desulfurization facility cable. Background technique [0002] At present, there are generally three desulfurization methods: pre-combustion, in-combustion and post-combustion desulfurization. With the development of industry and the improvement of people's living standards, the thirst for energy is also increasing. SO2 in coal-fired flue gas has become the main cause of air pollution, and the plugging operation of cables in desulfurization facilities has also become a top priority. Reducing SO2 pollution has become an urgent task of today's atmospheric environment governance. [0003] The plugging devices for thermal power plant boiler bodies and desulfurization facility cables in the market often cause large-scale damage to the outside atmosphere during d...
