Blast furnace gas holder is a kind of gas holder and one of the "new dry gas holders" in dry gas holders.
As an important equipment for industrial and civil gas fuel storage, energy saving and environmental protection, gas holder has a history of several decades in China, but the self-design and manufacture of dry gas holder began in 1980s. At present, there are mainly four types of dry gas holders in the world: 1. Dry oil rubber sealing type; 2. Rubber curtain sealing type; 3. Seal the thin oil metal slide plate; 4. New dry gas holder. 1 model is not widely used because of its poor sealing effect; The second storage pressure is low (about 3kPa) and the pressure fluctuates greatly, which limits its application range. The third sealing effect is better, the storage pressure is higher, the pressure fluctuation is smaller, and the application scope is wider. However, due to the limitation of its structural type, the storage pressure can not be further improved, the life of sealing mechanism is short, the processing capacity of cabinet structure is large, the precision requirement is high, the construction period is long and the investment is high. Fourthly, the new dry gas holder adopts a cylindrical structure, with an arched top and a thin oil glue seal for the piston. It is suitable for large-scale and high-pressure, and has the advantages of reasonable structure, stable piston operation, good sealing performance, long service life, safety and reliability, light cabinet weight, low investment and fast construction. The new dry gas holder will gradually replace the previously widely used thin oil metal sliding plate sealed gas holder. ?
