Description

Single-stage rubber membrane sealed gas holder

technical field

The utility model relates to a single-section rubber membrane sealing type gas cabinet.

Background technique

In the domestic iron and steel metallurgy industry, single-stage rubber-membrane-sealed gas holders are mainly used to store blast furnace gas or converter gas. Because of their simple production, convenient operation, and fast piston operation, they are more and more popular among users. In the prior art, the bottom of the single-stage rubber-membrane-sealed gas cabinet adopts a round arch, which is intended to facilitate the discharge of condensed water and dust. However, with the recovery of blast furnace gas and converter gas, more and more dry dust removal is used. , The gas entering the gas holder has less dust, high temperature and increased corrosive substances. The gas condensed water that is continuously precipitated in the gas cabinet flows along the upper surface of the arched cabinet bottom plate to the side plate. The concentration of corrosive substances in the gas condensed water is high, and the bottom plate of the gas cabinet is continuously washed and corroded. At the same time, the high temperature and oxygen content of the gas act as a catalyst for corrosion. The bottom plate of the cabinet will soon produce leaks due to corrosion, leaking gas, and endangering safe production. However, it is difficult to find the location of the leaks on the bottom plate of the cabinet, and it is difficult to overhaul.

However, with the recovery of blast furnace gas and converter gas, more and more dry dust removal is used, and the gas entering the gas cabinet has less dust and less dust. The temperature is high and the corrosive substances increase. The gas condensed water that is continuously precipitated in the gas cabinet flows along the upper surface of the arched cabinet bottom plate to the side plate. The concentration of corrosive substances in the gas condensed water is high, and the bottom plate of the gas cabinet is continuously washed and corroded. At the same time, the high temperature and oxygen content of the gas act as a catalyst for corrosion. The bottom plate of the cabinet will soon produce leaks due to corrosion, leaking gas, and endangering safe production. However, it is difficult to find the location of the leaks on the bottom plate of the cabinet, and it is difficult to overhaul.

As shown in Figure 2, the single-stage rubber-membrane-sealed gas cabinet of this embodiment includes a cabinet body, a cabinet bottom plate 21, a sealing mechanism 14 arranged between the cabinet body and the piston 13, a piston leveling device 15, and an automatic gas release mechanism. pipe 16; the cabinet body includes a cabinet top 11 and side walls 12; wherein, the cabinet bottom plate 21 is a plane bottom plate, and the upper surface of the plane bottom plate is covered with a protective water layer 22.
