Embodiment 1

[0049] A sprinkler unit such as Figure 1-Figure 3 As shown, it includes a spray plate 1 and a connecting piece 2, wherein the spraying plate 1 includes a plate body 11 and a dispersion water channel 12 passing through the plate body 11; the connecting piece 2 is used to connect the plate body 11 to the water outlet; the connection The part 2 is provided with a large particle discharge port 3 located between the disc body 11 and the water outlet.

[0050] Through the optimal setting of the above-mentioned disc body and dispersed water channel structure, the liquid discharged from the water outlet can be effectively shunted, and then the purpose of liquid spraying can be realized; at the same time, the connecting piece can not only effectively realize the connection between the disc body and the water outlet, Moreover, the large particle discharge port provided on it can also discharge the large solid particles through the large particle discharge port when there are large soli...

Embodiment 2

[0059] A leachate reflux system for dry anaerobic fermentation, comprising a reflux system body, the water outlet of the reflux system body is provided with the spraying part described in Example 1. In this setting mode, the filter structure in the backflow system body, such as the filter tank, can be effectively omitted, and the leachate from dry anaerobic fermentation can be directly pumped into the spraying part through the pump to save filtration equipment costs while improving cycle efficiency.

[0060] Specifically, the return system body includes: a spray pipeline 5 , the spray components described in Embodiment 1, an outlet pipeline 6 and a return pump 8 . Wherein, one end of the spray pipeline 5 extends into the anaerobic fermentation tank 4, and the spray component is installed on the water outlet of the spray pipeline 5; Connected, and then effectively pump the leachate drawn out of the lead-out line 6 into the spray line 5, and then spray back into the anaerobic f...

Abstract

The invention discloses a spraying component and a leachate reflux system for dry anaerobic fermentation formed by the spraying component. The spraying component comprises a spraying disc, and a connecting piece; the spraying disc is composed of a disc body, and a dispersing water channel penetrating through the disc body; the connecting piece is used for connecting the disc body to a water outlet; and the connecting piece is provided with a large particle discharge port positioned between the disc body and the water outlet. The spraying component can overcome the defect of liable spray header blockage when leachate is returned to a spray system for spraying without deep filtration in existing dry anaerobic fermentation; and thus, the spraying component has the advantage that the spray header is not blocked when the leachate is subjected to reflux spraying.

Description

technical field [0001] The invention relates to the technical field of sprinklers, in particular to a sprinkler component and a leachate reflux system for dry anaerobic fermentation composed of the sprinkler components. Background technique [0002] Dry anaerobic fermentation is a new technology that has developed very rapidly in recent years, and has a good application prospect in livestock and poultry manure treatment, straw gas production, and kitchen waste treatment. It has the advantages of low requirements for raw material pretreatment, less biogas slurry output, less energy, and convenient management. [0003] Among them, the dry anaerobic fermentation method of leachate reflux is widely used, and the leachate reflux is usually used to achieve mass transfer and heat transfer; while the leachate usually contains solid matter, before the reflux for spraying, the conventional method is to first Filtration is performed to filter out solid matter before spraying. This met...
