Embodiment 1

[0054] A high solid content organic matter hydrolysis acid generation system, its structure is as follows figure 1 Shown: including crushing device 1, feed pipe 2, vacuum air explosion device 3, valve 4, vacuum pump 5, hydrolyzate return pipe 6, hydrolyzate storage tank 7, hydrolyzate return pump 8, microwave device 9, hydrolyzate outlet 10. Hydrolyzate storage tank 11 , hydrolyzate return pipe 12 , hydrolyzate return pump 13 .

[0055] After the organic material is pulverized by the crushing device 1, it is transported to the vacuum air explosion device 3 through the feed pipe 2 to carry out the hydrolysis and acid production process of anaerobic fermentation. The diameter of the feed pipe 2 is 10-30 cm, preferably 15-20 cm. In this embodiment 15cm, the shape of the vacuum air explosion device 3 is a cylinder, and the inner wall is equipped with pH and temperature probes;

[0056]Before hydrolysis to produce acid, vacuum pump 5 is utilized to evacuate the vacuum air explosio...

Abstract

A system and method for hydrolyzing organic matter with high solid content to produce acid. Batch feeding, the organic material is crushed by the crushing device and then input into the vacuum air explosion device for fermentation and hydrolysis under vacuum. During the fermentation process, the hydrolyzate of the previous batch in the hydrolyzate storage tank is returned to the The vacuum air explosion device returns the previous solid hydrolyzate in the hydrolyzate storage tank to the vacuum air explosion device through the hydrolyzate reflux device, which can improve the rate and efficiency of organic matter hydrolysis.

Description

technical field [0001] The invention relates to the technical field of energy conversion and resource recovery of organic solid waste, in particular to a system and method for hydrolyzing organic matter with high solid content to generate acid. Background technique [0002] Anaerobic fermentation technology can convert organic matter into usable biogas, which can be divided into wet anaerobic fermentation and dry anaerobic fermentation. At present, the engineering application is mainly wet anaerobic method, and the moisture content of the material is below 10%. When dealing with solid waste such as straw, household garbage, kitchen waste, etc., it is necessary to add water to reduce the moisture content of the material. There are low concentration of products after fermentation, Dehydration treatment is relatively difficult, and it is easy to cause secondary pollution and other problems. Dry anaerobic fermentation refers to the anaerobic fermentation process with a total so...
