Working principle of dry gas holder

We know that the gas holder is a very large gas storage tank, which is welded from steel and widely used for the storage of chemical gas and city gas. Then the gas holder is divided into dry gas holder and wet gas holder. What is the working principle of dry gas holder? In fact, it is very simple. The dry-type gas holder uses the internal large-area piston to maintain and adjust the output pressure. The installation accuracy and component processing accuracy are relatively high, and the construction difficulty is greater than that of the wet-type gas holder. However, the floor area is relatively small, the storage pressure is high, the stability ratio is good, the service life is long, and the steel is less polluting the environment.
The Wiggins dry gas tank is usually used for the dry gas tank, which is composed of the main parts of the gas tank base plate, column, side wall plate, cabinet top frame, piston system, sealing device, balance device, etc., and is equipped with walkway platform, ladder and auxiliary devices for inspection and operation, such as internal lifting cage and rescue device, external elevator, venting and purging device, etc. The dry-type gas holder is in the shape of regular polygon. A large I-beam is erected at the top corner of the cylinder as a connecting piece for connecting the side wall panels and the lifting track for floating the large piston. The side wall of the cylinder is made of the pressed wall panels, which are stacked and welded. The top frame of the cabinet adopts the section steel truss structure. The top plate of the cabinet is made of steel plates or welded by the pressed panel. The cabinet top is equipped with ventilation and ventilation devices. In the gas holder, there are regular polygon pistons corresponding to its shape, and concrete prefabricated blocks are pressed on the piston to adjust the output gas pressure. There are flexible sealing devices around the piston, which can be divided into thin oil sealing and rubber curtain sealing according to the sealing form. The structure of the piston is different due to its different sealing forms. The piston frame of the thin oil seal gas tank is a steel truss, and the bottom of the frame is welded with steel plate to seal it. The piston of the rubber curtain sealing gas holder is composed of a piston plate welded with steel plate, a concrete bracket, a bracket, a piston strut, etc.
The above is a brief introduction of the manufacturer of dry gas holder installation. I hope it can help you.
