Embodiment

Specific embodiment of the present utility model is described in detail below in conjunction with accompanying drawing.It should be appreciated that herein Described embodiment is merely to illustrate and explained the utility model, is not limited to the utility model.

In the utility model, in the case where not making opposite explanation, the noun of locality such as " upper and lower, " used typically refers to " inside and outside " refers to be inoculated with the inside and outside of tank above and below inoculation tank.

The utility model provides a kind of inoculation tank for dry type stalk fermentation, and the inoculation tank includes cylindric and top and opened The tank body 1 put and at least two pipeline 2 connected respectively with the tank body 1, the pipeline 2 include prolonging outside the tank body 1 The straight length of inside is extended, the bearing of trend of the straight length deviates from the central axis of the tank body 1, each straight length Along the tank body 1 short transverse projection from the sensing of the external-to-internal of tank body 1 in arranged clockwise or in the inverse time Faller gill arranges.

Fig. 1 is illustrated that the schematic diagram of the inoculation tank with 3 pipelines 2, due to the extension side of the straight length of each pipeline To the central axis and the projection of the short transverse along the tank body 1 of each straight length for deviating from the tank body 1 from described The sensing of the external-to-internal of tank body 1 (is arrived in tank body 1 in arranged clockwise along the end outside tank body 1 of straight length The direction at end finish up successively each straight length of phase grounding connection when, the order of connection is counterclockwise), the inoculation tank that the application provides can So that methane backeria and biogas slurry the formation eddy flow in tank body 1 of inoculation tank are passed through from different pipelines, so that methane backeria and natural pond Liquid fully reacts, so as to improve the reaction efficiency between methane backeria and biogas slurry so that it is inoculated between methane backeria and biogas slurry uniformly, this The inoculation tank that application provides is not required to the driving equipment by the external world, fully relies on the potential energy or dynamic of methane backeria or biogas slurry itself Can, it is simple in construction convenient to carry out.Wherein, pipeline 2 could be arranged to straight tube, ensure that methane backeria and biogas slurry unimpededly flow into tank body 1 It is interior.

It is desirable that, it is generally the case that the required amount for being passed through methane backeria is less than the amount of biogas slurry of being passed through, therefore ventilating methane bacterium The quantity of pipeline 2 is less than the pipeline 2 of logical biogas slurry, and inoculation tank as shown in Figure 1 has 3 pipelines 2, then can select 1 pipeline 2 Ventilating methane bacterium, 2 pipelines 2 lead to biogas slurry.

Preferably, multiple pipelines 2 is identical with the height of the position of the tank body 1 connection, i.e. multiple pipelines 2 go out The height and the height all same of end and source of supply of mouth, the methane backeria or biogas slurry for ensureing the different pass-outs of pipeline 2 have Identical gravitional force, be advantageous to methane backeria and biogas slurry and equably mixed in tank body 1.

Preferably, the pipeline 2 is arranged on the top of the tank body 1, and due to the open-top of tank body 1, pipeline 2 can be set Put in the upper end of the wall of tank body 1, compared to pipeline 2 is run through on the wall of tank body 1, enable to the space of tank body 1 by most Bigization ground utilizes.Wherein, welding can be used between the end face of the wall of pipeline 2 and tank body 1.

In order to form intensity eddy flow as big as possible, it is preferable that the end in the tank body 1 of each pipeline 2 The height at place is less than the height where the end outside the tank body 1 of each pipeline 2, then the methane backeria in pipeline 2 Or biogas slurry can just have before tank body 1 is entered larger gravitional force and in the horizontal direction on kinetic energy so that methane Bacterium or biogas slurry can be sprayed, and intensity that is farther and being mixed to form eddy flow is bigger, promotes the reaction of methane backeria and biogas slurry.

Appropriate angle should be selected between pipeline 2 and tank body, to be supplied in methane backeria or the appropriate horizontal direction of biogas slurry Kinetic energy, also it may be preferred that the cross section of the pipeline 2 and the tank body 1 angle be less than 45 °, more preferably, the pipeline 2 Angle with the cross section of the tank body 1 is 30 °.It should be noted that this is the numerical value that present embodiment is selected, selection Concrete numerical value can be set according to the specific size of pipeline 2 and tank body 1.

Preferably, the inoculation tank includes N number of pipeline 2, and the axis per two adjacent pipelines 2 is in the tank The angle of projection on the same cross section of body 1 is 360 °/N, and N is more than or equal to 3, so that pipeline 2 is along 1 uniform cloth of tank body Put so that the inoculation between methane backeria and biogas slurry is uniform.

In addition, according to other side of the present utility model, a kind of inoculation system for dry type stalk fermentation is also provided, The inoculation system includes the methane backeria culture dish and stalk fermentation tank of inoculation tank as described above and the connection inoculation tank, institute State methane backeria culture dish and connect a part of pipeline 2 in multiple pipelines 2, the stalk fermentation tank connection is remaining The pipeline 2.

The inoculation system that the application provides is not required to the driving equipment by the external world, fully relies on methane backeria or biogas slurry itself Potential energy or kinetic energy form eddy flow in tank body 1, promote the reaction of methane backeria and biogas slurry, inoculation is uniformly and efficiency is higher.

Preferred embodiment of the present utility model, still, the utility model and unlimited is described in detail above in association with accompanying drawing In this.In range of the technology design of the present 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 should equally be considered as the utility model institute Disclosure, belong to the scope of protection of the utility model.
