Example Embodiment

[0034] Example 1

[0035] A biogas slurry filter with a biodegradable filter material, comprising a box body 1. The top of the box body 1 is provided with a floating filter material filling port 10 and a fixed filter material filling port 12, a liquid inlet 7 is provided in the middle, and a liquid inlet 7 is provided at the bottom. There is a slag outlet 9; the liquid inlet 7 divides the inner cavity of the box body 1 into a floating filter chamber 4 at the upper part of the liquid inlet and a sedimentation chamber 6 at the lower part of the liquid inlet. The floating filter chamber 4 is provided with a floating filter The slag outlet 9 is connected to the precipitation chamber 6, the floating filter material filling port 10 is connected to the floating filter material chamber 4; the fixed filter material filling port 12 is connected to the floating filter material chamber 4 through the fixed filter material chamber 5, and is connected A grid 2 is provided at the location, a fix...

Example Embodiment

[0043] Example 2

[0044] This embodiment is basically the same as the previous embodiment, and the main differences are:

[0045] The ribs 3 are annular ribs, at least 4 layers are distributed in the floating filter chamber 4, and the spacing is 3 times the width of the ribs 3. The width dimension of the rib 3 is 1 / 5 of the width of the box body. The volume of the floating filter chamber 4 is 1 / 3 of the tank volume; the volume of the precipitation chamber 6 is 2 / 3 of the tank volume; the volume of the fixed filter chamber 5 is 1 / 50 of the tank volume.

[0046] In this embodiment, the degradable filter material used has the characteristics of a sedimentable discharge filter, and only needs to be periodically supplemented according to the consumption of the filter material for long-term stable operation, and the quality of the filtered biogas slurry is stable and controllable.

Example Embodiment

[0047] Example 3

[0048] This embodiment is basically the same as the previous embodiment, and the main differences are:

[0049] The ribs 3 are annular ribs, at least 5 layers are distributed in the floating filter chamber 4, and the spacing is 6 times the width of the ribs 3. The width dimension of the rib 3 is 1 / 50 of the width of the box 1. The volume of the floating filter chamber 4 is 2 / 3 of the volume of the tank 1; the volume of the precipitation chamber 6 is 1 / 3 of the volume of the tank 1; the volume of the fixed filter chamber 5 is 1 / 300 of the volume of the tank 1. .

[0050] In this embodiment, the parameters are related to each other, and the change of one parameter will cause the change of other parameters. Because there are many related parameters, it is impossible to obtain through limited tests, especially the relevant parameters of the ribs can ensure the filter float The water flow in the filter chamber is not short-circuited.

Abstract

The invention discloses a degradable filter material biogas slurry filter and a filtering method of the degradable filter material biogas slurry filter. The degradable filter material biogas slurry filter comprises a box body, wherein a floating filter material filling hole and a fixed filter material filling hole are formed at the top of the box body, a liquid inlet is formed at the middle part of the box body, and a slag hole is formed at the bottom of the box body; the liquid inlet divides the inner cavity into a floating filter material chamber at the upper part of the liquid inlet and a sedimentation chamber at the lower part of the liquid inlet, a floating filter material is arranged inside the floating filter material chamber, the slag hole is communicated with the sedimentation chamber, and the floating filter material filling hole is communicated with the floating filter material chamber; and the fixed filter material filling hole is communicated with the floating filter material chamber by virtue of the fixed filter material chamber, a grid is arranged at a communication part, a fixed filter material is arranged inside the fixed filter material chamber, and the fixed filter material chamber is connected with a liquid outlet. By adopting the degradable filter material biogas slurry filter, flushing and back washing are not needed, the degradable filter material biogas slurry filter can stably operate for a long time while a filter material is supplemented periodically, and quality of filtered clear solution is stable and controllable.

Description

technical field [0001] The invention relates to the field of filter equipment, in particular to a biogas slurry filter with degradable filter material and a filtering method thereof. Background technique [0002] Existing biogas projects pursue gas production efficiency, the fermentation concentration is high, and the output biogas slurry is viscous and has high suspended solids, so it is not suitable for direct application as organic fertilizer. Such biogas slurry can be used as biogas slurry fertilizer for sprinkler irrigation and drip irrigation after filtering suspended solids through biogas slurry filtration equipment. However, the existing biogas slurry filtration equipment has low applicability and cannot achieve long-term stable production. However, a large amount of biogas slurry cannot be used as fertilizer, which will inhibit the operation of the biogas project and cause serious pollution. [0003] Currently commonly used biogas slurry filtration equipment mainly...
