A brush seal device for a gas cabinet

Abstract

The invention discloses a brush type sealing device for a gas holder. The brush type sealing device is installed between a piston of the gas holder and the inner wall of a holder body and comprises a brush seat, a brush and a wear resistance layer. The brush seat is connected with the piston. The brush is installed on the brush seat with multiple layers in a staggered manner. The wear resistance layer is wear-resistance coating smeared to the inner side wall of the holder body. The brush is of a thin metal wire bending structure. Bristles of the brush are of a bidirectional bent structure. Due to the fact that tiny gaps are formed between thin metal wires of the brush and the gaps are uneven, even incoming flow becomes uneven after entering the bristles of the brush; and due to the fact that flowing is destroyed by the bristle bundle and the unevenness of flowing is ensured, a self-sealing effect is generated for the fluid. The brush type sealing device has the beneficial effects that the brush type sealing device is suitable for gas holders with various volumes, the structure is simple, stability is good, maintenance is convenient, the brush only needs to be replaced regularly, cost is low; and by means of the sealing device, the invalid volume of the gas holder is small, and construction cost is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of gas cabinets, in particular to a brush-type sealing device for a gas cabinet. Background technique [0002] As the low-carbon economy has gradually become the goal of economic and industrial development in various countries, and my country's environmental policy has also become more and more perfect, low-carbon production has become a very urgent issue in front of energy-consuming enterprises such as iron and steel metallurgy. Among them, as an important device for iron and steel enterprises to improve the comprehensive utilization rate of energy, the gas cabinet is more and more widely used. The function of the gas cabinet is to recover the instantaneous excess gas caused by the unbalanced production of throughput, and cooperate with the buffer user to achieve the ideal effect of pipe network voltage stabilization and energy saving. [0003] Gas holders are divided into two types: wet gas holders and dr...

AI Technical Summary

Problems solved by technology

Thin oil-sealed and dry-oil-sealed gas holders are complex in structure, difficult to maintain, and have a high one-time construction investment; although rubber-membrane-sealed gas holders have simple sealing methods, good sealing performance, and less maintenance workload, they are not suitable for large-scale development. For the trend of gas holders with good capacity, good stability, and easy maintenance, there is a bottleneck problem. For example, after the capacity of the gas cabinet is increased, the height of the rubber membrane will be increased, which requires a higher strength of the rubber membrane. However, this is limited by the current rubber Membrane Manufacturing Process

It can be seen that the gas holders of the above three traditional sealing methods have certain disadvantages in the development of large-scale gas cabinets, which hinder the process of large-scale gas cabinets
