Briefly describe the manufacture and installation of gas holder

1、 Type and mechanism of gas holder
Gas holder, gas tank. A kind of container equipment used to store various industrial gases and balance the non-uniformity of gas demand. It can be divided into low pressure gas holder and high pressure gas holder. The former has wet and dry structures. Various materials.
1. Low pressure wet gas holder
It is mainly composed of sink and bell cover.
(1) Vertical low pressure wet gas holder.
Its structure is composed of water tank, bell housing, tower section, water seal, top frame, guide rail column, guide wheel, counterweight and anti-vacuum device.
(2) Screw type low pressure wet gas holder.
Its structure is composed of water tank, tower section, bell guard, guide rail, platform, top plate and top frame, air inlet and outlet pipe, etc.
2、 Fabrication and installation construction method of wet gas holder
1. Prefabrication of gas holder
The wall plates, platforms, side rings on the top of the cover and the hanging rings, bottom rings, upper and lower seals of the movable tower sections are one of the key parts of the gas tank manufacturing and installation process. Their prefabrication quality standards are high, and each construction process is subject to special inspection,
2. Gas holder installation and construction method
The assembly of the bell cover, middle section and water tank wall of the low pressure wet gasometer can be divided into reverse installation method and front installation method.
(1) The inverted installation method is to install the bell jar section by section outward, and finally assemble the sink wall.
(2) The positive installation method is to start from the assembly and welding of the water tank wall and install it section by section to the inside, and finally assemble the bell cover and middle section.
The above is the brief information of the manufacturer of the gas holder.
