The flow area in the cloth channel 2 of the cylindrical groove 1 is radially relatively distant from the discharge port 21, to pass through
The larger cloth channel 2 of flow area conveys more materials to apart from 1 farther position of cylindrical groove.
Wherein, the different height of cylindrical groove 1 is may be arranged at along the axial direction of cylindrical groove 1 with the cloth channel 2 in group
Position.It is, however, preferable that with the cloth channel 2 in group along the circumferential direction of cylindrical groove 1 on the sustained height of cylindrical groove 1
It is uniformly distributed, is on the one hand easily installed cloth channel 2 in this way, be on the other hand convenient for stalk material in sustained height cloth, so as to
Uniformly diffusion.In addition, the cloth channel 2 of different groups may be arranged at the different height of cylindrical groove 1 along the axial direction of cylindrical groove 1
Position, and in order to reduce the size or height of cylindrical groove 1 in axial direction, it is preferable that each cloth channel 2 is communicated in institute
State the mutually level position of cylindrical groove 1.Also, it is highly preferred that along the axial direction of the cylindrical groove 1, the cylindrical groove 1
Height is equal with the height in the cloth channel 2.It is also convenient for determining the link position in cloth channel 2 and cylindrical groove 1 in this way.Its
In, the height of cylindrical groove 1 can be selected according to the size and stalk supply demand of fermentation tank, processed and made for convenience
It makes, it is preferable that the value range of the height of the cylindrical groove 1 is 0.5-1.5m.
The utility model second aspect provides a kind of stalk marsh gas system, and the stalk marsh gas system includes feed pipe, hair
The feed inlet 11 of fermentation tank and above-mentioned stalk marsh gas distribution device, the feed pipe and the stalk marsh gas distribution device connects
Logical, the discharge port 21 in the cloth channel 2 is connected to the fermentation tank.Since the stalk marsh gas system includes above-mentioned stalk marsh gas
Distribution device, and in the stalk marsh gas distribution device, the circumferential direction of cylindrical groove is provided with multigroup cloth channel, and more
Group cloth channel is different along the length of the radial direction of cylindrical groove, so as to make stalk along the different distributions of cloth channel 2 to away from
Far and near positions different from cylindrical groove 1, realization are uniformly distributed, and are conducive to improve fermentation efficiency and are increased gas production, while structure
It is simple and convenient to operate and cost is relatively low.
Wherein, it is uniformly distributed to enable stalk to pass through distribution device, it is preferable that sent out described in 1 face of the cylindrical groove
The center of fermentation tank.Certainly, cylindrical groove 1 is arranged also in the other positions of fermentation tank.
In addition, the group number and every group of cloth of the diameter of cylindrical groove 1 and the cloth channel being arranged in its circumferential direction
Expect channel along the length of the radial direction of cylindrical groove 1 can according to the diameter of fermentation tank and in actual work cloth doses needs come into
Row design, it is preferable that the value range of the diameter of the cylindrical groove 1 is 1-3m；Multigroup cloth channel 2 includes first group
Cloth channel 10 and second group of cloth channel 20, length and the hair of the first group of cloth channel 10 along the radial direction
The ratio of the radius of fermentation tank is 0.5-0.8；First group of cloth channel 10 and second group of cloth channel 20 are along the diameter
Ratio to the length in direction is 0.2-08.
Also, stalk marsh gas distribution device with respect to fermentation tank installation site there are many selection, it is preferable that the straw biogas
Gas distribution device is arranged in the top of the fermentation tank, and the cloth channel 2 is tube body, and the tube body free end is parallel to institute
The axial direction for stating cylindrical groove 1 extends towards the fermentation tank bending.That is, stalk marsh gas distribution device is arranged in the hair
The outside of fermentation tank is so that it is convenient to install, and stalk transmits in closed tube and is not easy to fall and lose and make external environment
At pollution.Selectively, the stalk marsh gas distribution device is arranged in the inside of the fermentation tank, and the cloth channel 2 is square
The free end of shape slot, the rectangular channel is opened wide to form the discharge port 21.Stalk marsh gas distribution device is arranged in fermentation tank
Inside, such fermentation tank is not easy gas leakage, it is preferable that stalk marsh gas distribution device can be arranged close to the top of fermentation tank, in this way
Facilitate the stalk received in feed pipe and the stalk of reception is evenly distributed in fermentation tank, and cloth channel is rectangular channel
When, stalk can be fallen into from the top notch of rectangular channel in fermentation tank, therefore be less prone to clogging, and transmission efficiency is higher.
Preferred embodiments of the present invention, still, the utility model and unlimited are described in detail above in association with attached drawing
In this.In the range of the technology design of the utility model, a variety of simple variants can be carried out to the technical solution of the utility model,
It is combined in any suitable manner including each particular technique feature.In order to avoid unnecessary repetition, the utility model
Various combinations of possible ways are no longer separately illustrated.But these simple variants and combination equally should be considered as the utility model institute
Disclosure belongs to the scope of protection of the utility model.
