PVC coated fabrics for biogas digester engineering

I What is biogas digester

The digester is teapot shaped with gas outlet hole, feed inlet, and material outlet, with pipes assembled. The diameter of the feed inlet and material outlet both are 200 300mm, big enough for the material goes in/out smoothly. Meanwhile the feed inlet and the material outlet are whole welded, not bolt connected, which makes it more light and better tightness.

Normally the digester can be installed under the ground, half under the ground, or on the ground, that depends on the 

local environment.

III Characteristics of soft biogas digester:
1.  Excellent heat absorption
Fermentation temperature is the key factor, at least 15 degree.C required by this technology. This modified membrane could absorb heat from sunshine for improvement of biogas production.
2,  Strong pressure resistance

For digester of reinforced PVC membrane, operation pressure could be up to 3 kPa; For PVC coated fabric, it can reach 8 kPa; What's more that the digester is equipped with pressure protecting mechanism.
3,  Good air tightness

The floating cover is hot-welded by multi-functional high frequency welding machine, with perfect performance of air tightness, in line with the requirements of anaerobic fermentation.
 

4,  Perfect stretchability

The reinforced PVC membrane is flexible, enables floating cover to expand about 10% larger.
5,  Strong weather appliability

The membrane chose is a kind of modified PVC alloy material, with good stability, can be antifreeze (-25 Degree.C) and anti-exposure(+50 Degree.C). It is also acid&alkali resistance, lightning protection, earthquake resistance and tear resistance. Life-time can reach 12~15 years.
6,   Easy operation&maintenance

It is easy to learn and master the complete processes. Short time of training enables worker to achieve a comprehensive grasp how to operate and maintain the whole digester.

5. high safety, no clear pool, no human dangerous.

6. effectively solve the problem of the Crusting

7. after the moving, can repeat to disassemble with only air.

8. short time limit, general just need 1 day can build the pool, and the next day can be put into use.

9. specialist himself, no need simple maintenance can begin.

10. built pool, the ground is flexible, can be built underground pool.
