Constant pressure type double-section rubber membrane sealed dry gas cabinet

Abstract

The invention relates to a constant pressure type double-section rubber membrane sealed dry gas cabinet comprising a cabinet body, a piston and a T-baffle. The piston and the T-baffle are both arranged in the cabinet body in an up-and-down moving manner, the outer wall of a side plate of the cabinet body is provided with a counter weight guide rail and a leveling counter weight arranged on the counter weight guide rail in a sliding manner, the outer wall of the side plate of the cabinet body is further provided with a pressure regulating counter weight and a pressure regulating driving mechanism for driving the pressure regulating counter weight to be switched between the pressure regulating state and the idle state, and the weight of the pressure regulating counter weight is equal to theweight of the T-baffle; in the pressure regulating state, the pressure regulating counter weight is connected with the leveling counter weight into a whole; and in the idle state, the pressure regulating counter weight is separated from the leveling counter weight and is placed on the side plate. Cooperating with the activity conditions of the piston and the T-baffle, through combination or separation of the pressure regulating counter weight and the leveling counter weight, the total weight of a balance counter weight of the piston is changed in time, the stability of the gas storage pressureof the gas cabinet can be achieved, and the gas quality of the downstream process is ensured.

Description

Technical field [0001] The invention belongs to the technical field of gas tanks, and specifically relates to a constant-pressure two-stage rubber membrane sealed dry gas tank. Background technique [0002] Rubber membrane sealed dry gas tanks are widely used in the recovery and storage of by-product gas from iron and steel enterprises. According to the number of sealed sections, rubber membrane tanks can be divided into single-stage, double-stage and multi-stage. At present, the mainstream in the market is double-stage Type and single-stage rubber membrane cabinet. [0003] Compared with the single-stage rubber membrane tank, the traditional double-stage rubber membrane sealed dry gas tank has obvious advantages. There is less useless space on the upper part of the piston, and the same gas storage volume can be realized in a smaller size. Wide application range. [0004] In the past production situation, the two-stage rubber membrane sealed dry gas tank is operating well and can w...

Problems solved by technology

However, with the development of industry, the pressure refinement of the gas pipeline network in iron and steel plants is getting higher and higher, especially for some processes that require high gas quality, and the pressure fluctuations of the supplied gas are often fed back, which affects these processes. The normal production of double-stage rubber membrane gas holders has limited the application
