Abstract

The invention belongs to the technical field of feeders, and particularly relates to a feeder for straw anaerobic fermentation gas making, which is arranged on the upper part of a reactor main body. The feeder comprises a feed port buffer, wherein the middle part in the feed port buffer is provided with a stirrer; one side of the stirrer is provided with a feed port, and the feed port is provided with a butterfly valve; the other side of the stirrer is provided with a gas inlet pipe and a gas outlet pipe; the top of the feed port buffer is provided with a sealing cover; the bottom of the feed port buffer is provided with a transverse spiral propeller; the transverse spiral propeller below the stirrer is provided with a baiting port; the discharge end of the transverse spiral propeller is arranged on the upper part in the reactor main body; the lower part of the discharge end of the transverse spiral propeller is provided with a discharge port; a spiral push rod is arranged inside the transverse spiral propeller; and the outer end of the transverse spiral propeller is provided with a motor. The feeder solves the problem of high blocking tendency in the feeding process, can implement continuous and stable feeding, and enhances the production efficiency.

Description

technical field [0001] The invention belongs to the technical field of feeding devices, and in particular relates to a feeding device for gas production through anaerobic fermentation of straw. Background technique [0002] With the depletion of fossil energy such as petroleum and coal, hydrogen, as a new type of renewable and clean energy, has attracted much attention. Among the various production methods of hydrogen, the production of hydrogen by anaerobic fermentation has attracted much attention because of its low energy consumption, fast hydrogen production rate, high stability, and wide range of available substrates. At present, most of the substrates used in the research of fermentation biohydrogen production are soluble sugar, starch and their corresponding organic wastewater. my country is a large agricultural country, and the output of crop straw is very large, which not only brings huge pressure on the environment, but also has low utilization efficiency. A larg...

AI Technical Summary

Problems solved by technology

The existing laboratory straw anaerobic fermentation to produce hydrogen has achieved remarkable results, but encountered difficulties in the process of producing a large amount of hydrogen. The specific performance is: the existing straw anaerobic fermentation gas production device is based on liquid Mainly, when straw is used as the substrate, due to the light specific gravity and strong flexibility of the straw fiber, the existing device can only introduce the liquid part of the feed into the reverser when feeding, and the straw itself is difficult to enter the reactor. Moreover, it is easy to cause blockage. In the case of difficult feeding, it will also make it difficult to discharge the reactor, which greatly reduces the hydrogen production of straw fermentation and seriously affects the production efficiency of the enterprise.
