Description

[0002] Traditional anaerobic reactors include USR, UASB, CSTR, PFR, etc. They use different water qualities for anaerobic fermentation. However, they all have the problem of scum and sludge discharge. Excessive accumulation of scum will cause tuberculosis on the top of the reactor, which will cause an accident in the reactor. It may even cause the reactor to be abandoned. Excessive accumulation of sludge that cannot be discharged will reduce the effective volume of the reactor fermentation, resulting in a decrease in the biogas production rate of the reactor. The mobile cage anaerobic reactor is to put solid waste into a box. It is moved to carry out hydrolysis, acidification, methanation and other steps to ferment organic matter. The scum and sludge are all left in the box, thus avoiding the problems that occur in other reactors.

[0003] Although the fixed cage anaerobic reactor solves the above problems, it is limited by the fixed cage. Only one reaction cycle can be performed at a time. The cage can be taken out to replace the anaerobic reaction raw materials only after the organic matter in the cage has reacted completely.

[0053] Working principle:

[0054] After the mobile net box 6 is filled with materials outside the tank body, the feeding crane 2 lifts the materials from outside the tank body to the feeding tank 4. Because it is below the liquid level, the hook of the feeding crane 2 cannot be removed from the mobile net box 6. In addition, due to the turbidity of the liquid, the mobile net box 6 cannot be accurately placed on the track 10 at the bottom of the tank. Therefore, after the feeding crane 2 lifts the materials into the feeding tank 4, the mobile net box 6 must be installed on the track entry device first. The mobile net box 6 is placed on the track 10 at the bottom of the tank body by the track entry device, and the mobile net box 6 moves along the slope of the track 10;

[0055] When the anaerobic fermentation of the material is completed, the mobile net cage 6 moves to the discharge pool 18 and is then removed by the derailing device and the discharge crane 19 .

[0056] This device can be used as a hydrolysis tank, acidification tank, and regulating tank for water treatment. It can also be used as a pre-treatment method for anaerobic reactors such as USR, UASB, CSTR, and PFR to solve the problems of scum and sludge.

[0057] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
