In the present invention, unless otherwise specified, terms such as "upper, lower, left, and right" and "upper, lower, left, and right" are used generically to refer to the upper, lower, left, and right illustrated in the drawings; "inner and outer" means the inner and outer relative to the contour of the respective component itself.
The existing straw biogas system adopting dry fermentation is not provided with a distributing device, or is provided with the distributing device, but the distributing effect is not ideal, so that the straw supply in the fermentation tank is uneven, namely the distribution of the straw in the fermentation tank is uneven, thereby influencing the fermentation efficiency and the gas production rate, and the normal working requirement can not be better met, or the distributing device has a complex structure, is inconvenient to operate and has higher cost.
Based on the problems of uneven distribution of straw or complex structure of a distribution device in the prior art, the invention provides a straw biogas distribution device and a straw biogas system with the same, which can solve the technical problems, and the straw biogas distribution device and the straw biogas system are described in detail below by specific embodiments and with the aid of corresponding drawings.
The invention provides a straw biogas distribution device which is used for conveying straws in a feeding pipe into a fermentation tank, and comprises a cylindrical groove 1 and a plurality of groups of distribution channels 2 which are respectively communicated with the cylindrical groove 1, wherein the groups of distribution channels 2 are arranged around the circumferential direction of the cylindrical groove 1 and have different lengths along the radial direction of the cylindrical groove 1, one axial end of the cylindrical groove 1 is provided with a feeding hole 11 communicated with the feeding pipe, the other axial end of the cylindrical groove is closed, and the free end of the distribution channel 2 is provided with a discharging hole 21.
In the above technical solution, as shown in fig. 1 and fig. 2, the straw biogas distribution device is used for conveying the straw in the feeding pipe into the fermentation tank, the straw biogas distribution device comprises a cylindrical groove 1 and a plurality of groups of distribution channels 2 respectively communicated with the cylindrical groove 1, the plurality of groups of distribution channels 2 are arranged around the circumferential direction of the cylindrical groove 1 and are different in length along the radial direction of the cylindrical groove 1, one axial end of the cylindrical groove 1 is provided with a feeding port 11 communicated with the feeding pipe, the other axial end is closed, and the free end of the distribution channel 2 is provided with a discharging port 21. Because the circumference direction around the cylindrical tank 1 is provided with multiunit cloth passageway 2, and multiunit cloth passageway 2 is different along the radial direction's of cylindrical tank 1 length to can make the straw distribute to the position far away from the cylindrical tank 1 difference along different cloth passageway 2, realize evenly distributed, be favorable to improving fermentation efficiency and increase the gas production, so that better satisfy the work demand, this distributing device simple structure, convenient operation and cost are lower simultaneously.
The communication mode between the distribution channel 2 and the cylindrical groove 1 is selected in various ways, for example, by welding, and the extending direction of the distribution channel 2 may not pass through the center of the cylindrical groove 1, however, in order to save materials or reduce the conveying time of the straw on the distribution channel 2, it is preferable that the distribution channel 2 extends along the radial direction. Alternatively, in order to facilitate the transfer of the straw on the distribution channel 2, the distribution channel 2 is arranged obliquely downwards and the projection of the distribution channel 2 extends along the radial direction, and the included angle between the distribution channel 2 and the cross section of the cylindrical groove 1 is 0-15 degrees. Wherein the angle between the cross section of the distribution channel 2 and the cylindrical groove 1 is not too large, which on the one hand results in material waste and on the other hand also increases the volume, resulting in inconvenient installation and a relatively reduced volume available in the fermenter for holding the fermentation product.
In addition, in order to uniformly distribute the straw in the fermenter, it is preferable that each group of the distribution channels 2 includes a plurality of the distribution channels 2 uniformly arranged around the circumferential direction of the cylindrical tank 1 and having the same length. On the one hand, the distribution channels 2 of each group can distribute materials at different positions on the same circumference taking the cylindrical groove 1 as the center so as to uniformly distribute materials on the circumference, and when the materials are distributed at one position, the materials of the straw spread around the position because of the specificity of the materials of the straw, so that the materials of the straw can be uniformly distributed at the positions nearby the inner part and the outer part of the circumference; on the other hand, by means of the plurality of groups of distribution channels 2, it is possible to distribute evenly around different circumferences centered on the cylindrical tank 1, so that an even distribution over substantially the entire cross section of the fermenter is achieved.

Wherein the distribution channels 2 in the same group may be arranged at different heights of the cylindrical groove 1 in the axial direction of the cylindrical groove 1. However, the distribution channels 2 in the same group are preferably distributed evenly over the same height of the cylindrical tank 1 in the circumferential direction of the cylindrical tank 1, which on the one hand facilitates the installation of the distribution channels 2 and on the other hand facilitates the distribution of the straw material at the same height for even diffusion. In addition, different groups of the cloth passages 2 may be arranged at positions of different heights of the cylindrical groove 1 in the axial direction of the cylindrical groove 1, and in order to reduce the size or height of the cylindrical groove 1 in the axial direction, it is preferable that each of the cloth passages 2 communicates with the positions of the same height of the cylindrical groove 1. And, more preferably, the height of the cylindrical groove 1 is equal to the height of the cloth path 2 in the axial direction of the cylindrical groove 1. This also facilitates the determination of the connection position of the cloth channel 2 with the cylindrical groove 1. The height of the cylindrical tank 1 can be selected according to the size of the fermentation tank and the demand of the straw supply amount, and for the convenience of processing and manufacturing, the value of the height of the cylindrical tank 1 is preferably in the range of 0.5-1.5m.

Because this straw biogas system includes foretell straw marsh gas distributing device, and in this straw marsh gas distributing device, around the circumference direction of cylindrical tank be provided with multiunit cloth passageway, and multiunit cloth passageway is different along the length of the radial direction of cylindrical tank to can make the straw distribute to the position far away from the cylindrical tank 1 difference along different cloth passageway 2, realize evenly distributed, be favorable to improving fermentation efficiency and increase the gas production, simple structure, convenient operation and cost are lower simultaneously.
Wherein, in order to uniformly distribute the straw through the distributing device, the cylindrical groove 1 is preferably opposite to the center of the fermentation tank. Of course, the cylindrical tank 1 is also arranged at other positions of the fermenter.
In addition, the diameter of the cylindrical tank 1, the number of groups of distribution channels arranged in the circumferential direction of the cylindrical tank 1 and the length of each group of distribution channels along the radial direction of the cylindrical tank 1 can be designed according to the diameter of the fermentation tank and the distribution amount in actual working, and the diameter of the cylindrical tank 1 is preferably 1-3m; the plurality of groups of distribution channels 2 comprise a first group of distribution channels 10 and a second group of distribution channels 20, and the ratio of the length of the first group of distribution channels 10 along the radial direction to the radius of the fermentation tank is 0.5-0.8; the ratio of the lengths of the first group of cloth passages 10 and the second group of cloth passages 20 in the radial direction is 0.2-0.8.
And, there are multiple choices in the installation position of straw marsh gas distributing device relative to the fermentation cylinder, preferably, straw marsh gas distributing device sets up the top of fermentation cylinder, distribution channel 2 is the body, just the body free end is parallel to the axial direction of cylindricality groove 1 towards the fermentation cylinder is bent and is extended. That is, the straw biogas distribution device is arranged outside the fermentation tank, so that the installation is convenient, and the straw is not easy to fall off to be lost and pollute the external environment when conveyed in the closed pipe body. Alternatively, the straw biogas distribution device is arranged in the fermentation tank, the distribution channel 2 is a rectangular groove, and the free end of the rectangular groove is opened to form the discharge port 21. The straw biogas distribution device is arranged in the fermentation tank, so that the fermentation tank is not easy to leak gas, preferably, the straw biogas distribution device can be arranged close to the top of the fermentation tank, so that straws in a feeding pipe are conveniently received and uniformly distributed in the fermentation tank, and when a distribution channel is a rectangular groove, the straws can fall into the fermentation tank from the notch at the top of the rectangular groove, thus the blockage phenomenon is not easy to occur, and the conveying efficiency is higher.
