Introduction of wet gas holder
Low-pressure wet gas holder belongs to metal cabinet which can change volume, composed of sink, tower section, bell jar and lift orientation device.
When the biogas enters in the gas holder, bell jar and tower section in sink will rise in turn(from small to large according to the diameter), when the biogas exports from the gas holder, bell jar and tower section descend to the sink in turn(from large to small according to the diameter). Between bell jar and tower section, inside and outside tower section, use water seal to isolate the biogas in the gas holder and the atmosphere. So the storage volume and pressure of the biogas is changing with the rise and drop of the tower section.
Low-pressure wet gas holder has simple structure, easy construction, running reliable and other characteristic, it is more economic for small volume gas holder to use.
Features of wet gas holder:
1. Low load of construction and cost.
2. Small footprint, can reduce the steel consumption.
3. The gas holder bears the snow load, not the piston, so the snow can't effect the gas pressure.
4. The gas in the storage can keep dry.
5. It is easy to repair when the foundation uneven subsidence.
6. The sealing liquid can be used under -30 centigrade, so needn't to consider the freezing in cold area.
7. The storage pressure is basically stable, generally from 1590 PA to 2000 PA, pressure fluctuation is not more than 100 PA to 150 PA.
Advantage
1. Made of Special Steel Plate, good corrosion resistance.
2. Low load of construction and cost.
3. Long service life (more than 15 years).
4. Convenient for construction.
5. less land occupation, can reduce the steel consumption.
6. The gas holder bears the snow load, not the piston, so the snow can't effect the gas pressure.
7. The gas in the storage can keep dry.
8. It is easy to repair when the foundation uneven subsidence.
9. The sealing liquid can be used under -30 centigrade, so needn't to consider the freezing in cold area.
10. The storage pressure is basically stable, generally from 1590 PA to 2000 PA, pressure fluctuation is not more than 100 PA to 150 PA.
11. Equipped with positive and negative pressure protector, operating safety is ensured.
Contrast
Compared with the Dry Gas Tank, the Dry Gas Tank has less steel volume, less machining elements and low construction difficulty. However, due to the existence of water seal device, the cabinet is easy to rust, and the maintenance cost is high. The Dry Gas Tank is constant and regulates the output pressure with the help of the internal large area piston rise and fall. The installation precision and the precision of the component processing are high, the construction is difficult, but the ground area is small, the storage pressure is high, the stability is good, the service life is long, the steel is saved, and the environmental pollution is less.
Principle
The Bell Cover is an open cylindrical structure with a vaulted bottom and a cylindrical movable column between the sink and the Bell Cover. The gas pipe passes through the sink bottom and the water in the sink into the Bell Cover to achieve the input or discharge of the gas. The upper and lower tower joints are connected by water seal and sealed. When the gas is pressed to the gas cabinet, the Bell Cover rises, and the lower hanging ring takes water from the sink; When the bell is raised to a certain height, the Bell Cover is connected with the hanging ring on the section of the tower, the second tower section is hung on the ring plate inserted under the Bell Cover hanging ring water seal, the second tower section is raised, so in turn, the tower section is mentioned. In the output gas, the Bell Cover and the tower section of the action process is reversed. The Bell Cover and the tower section depend on the guide rail and the Guide wheel to guarantee the fluctuation smoothly.
