Description

Technical Field

[0001] The invention belongs to the technical field of environmental protection, and in particular relates to a biogas residue self-filtration water system. Background Art

[0002] Biogas is one of the clean energy sources. The sludge after biogas fermentation is a high-quality fertilizer, but the sludge contains a large amount of liquid biogas, so it needs to be separated into dry and wet parts. Currently, dry-wet separators, plate and frame filter presses, and mesh belt filter presses are commonly used to separate the liquid biogas from the sludge. However, when the sludge is separated, the fine sludge is discharged with the liquid biogas. Especially when the amount is large, these equipments are slow to process and require a lot of electricity. Summary of the invention

[0003] The present invention aims to solve the above technical problems at least to a certain extent. To this end, the present invention aims to provide a biogas residue self-filtration water system.

[0006] Preferably, a sun shed is provided on the material storage tank. The sun shed is provided with at least one air outlet.

[0007] Preferably, filter material is arranged in the filter material tank. The bottom of the filter material tank is an inclined diversion slope, and the bottom of the diversion slope is a flat bottom, an arc bottom or a V-shaped bottom.

[0008] Preferably, the filter material troughs are provided in plurality, and a transport vehicle wheel area is provided between the filter material troughs. When the filter material troughs are provided in plurality, they are arranged with spacing therebetween, and the filter material troughs are arranged in parallel or separated with spacing therebetween.

[0009] Preferably, the perforated plate is evenly distributed with leakage holes.

[0010] The beneficial effects of the present invention are:

[0011] The biogas residue self-filtration system provided by the present invention utilizes solar energy without additional energy consumption, can process biogas residue in large quantities, and achieves biogas residue dehydration and drying. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and are not to be construed as limiting the present invention. The components of the embodiments of the present invention generally described and shown in the drawings herein may be arranged and designed in a variety of different configurations.

[0018] In the present invention, unless otherwise clearly stipulated and limited, terms such as "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal connection of two elements.

[0019] Embodiment 1

[0020] like Figure 1 As shown, a biogas residue self-filtration system of this embodiment includes a material storage tank 1, three filter material troughs 2 at the bottom of the material storage tank 1, the filter material troughs 2 are arranged in a soil layer 9, there is a spacing between the three filter material troughs 2, and the three filter material troughs 2 are arranged in parallel, and a transport vehicle wheel area 7 is provided between adjacent filter material troughs 2, so that the transport vehicle can directly enter the material storage tank 1 to transport the biogas residue that needs to be processed out of the material storage tank 1. .

[0021] The bottom of the filter material tank 2 is an inclined diversion slope 6, and the bottom of the diversion slope 6 is a flat bottom. The diversion slope 6 is connected to the biogas slurry storage tank. The filter material tank 2 is provided with a perforated plate 3, and the perforated plate 3 is evenly distributed with leakage holes.

[0022] The upper part of the material storage tank 1 is covered with a transparent light-transmitting material to form a sun shed 4, and an air outlet is provided on the sun shed 4 to prevent rainwater from entering.

[0023] The biogas residue is transported to the material storage tank 1, and the biogas liquid in the biogas residue falls into the filter material trough 2 from the leakage holes of the perforated plate 3. Under the action of gravity, the biogas liquid flows along the guide slope 6 to the biogas liquid storage tank connected to the guide slope 6 for standby use; sunlight shines into the material storage tank 1 through the transparent sun shed 4 to increase the temperature in the material storage tank 1, and the residual water in the biogas residue evaporates and is discharged from the vent, and the remaining biogas residue is the dry residue 8, which can be used as an organic fertilizer.

[0024] Embodiment 2

[0025] like Figure 2 and Figure 3 As shown, a biogas residue self-filtration water system of this embodiment is based on the first embodiment. The filter material trough 2 is filled with filter material 5. The filter material 5 can be made of river sand or sawn wood. The filtering effect of the filter material 5 can further separate the biogas residue and the biogas liquid, so that the biogas liquid flowing into the biogas liquid storage tank contains no or less biogas residue.

[0026] It should be noted that, in other embodiments, the number of the filter material tank 2 may also be one.

[0027] It should be noted that if Figure 4 As shown, in other embodiments, the bottom of the guide slope 6 is an arc-shaped bottom or a V-shaped bottom.

[0028] The present invention is not limited to the above-mentioned optional implementation modes. Anyone can derive other various forms of products under the inspiration of the present invention. However, no matter what changes are made in the shape or structure, all technical solutions that fall within the scope defined by the claims of the present invention fall within the protection scope of the present invention.
