Organic garbage treatment equipment having pH adjustment function

Abstract

The invention relates to organic garbage treatment equipment having a pH adjustment function. The organic garbage treatment equipment comprises a main body, wherein the main body is provided with a feeding port, a crushing mechanism and a stirring mechanism, the crushing mechanism comprises a crushing unit, a crushing box and a control unit, the crushing unit comprises a first motor, a first gear,a second gear and two rollers, and the stirring mechanism comprises a reaction tank, a third motor, a third gear, a pH sensor, a second valve, a third valve, a neutralization unit and two mixed units, the organic garbage treatment equipment having the pH adjustment function can pulverize large-volume organic garbage into small-particle organic garbage through the crushing mechanism, the organic garbage degraded speed of the organic garbage treatment equipment is increased, and the organic garbage treatment equipment can maintain the weak alkali environment in a reaction tank by quantitativelyadding the lime milk, which can prevent the pH value from being too low to affect the growth of the methane bacteria.

Description

technical field [0001] The invention relates to the field of organic waste treatment equipment, in particular to organic waste treatment equipment with pH adjustment function. Background technique [0002] Organic waste treatment equipment refers to the physical, chemical and biological treatment of organic waste and its pollutants to reduce environmental pollution and even turn waste into treasure. Among them, anaerobic fermentation of organic waste to produce methane is an important Some organic waste treatment equipment mainly use the biodegradation method. [0003] Methane bacteria are very sensitive to changes in pH value. It is absolutely necessary to maintain a weak alkaline environment. The optimal pH range of methane bacteria is 6.8-7.5. When the pH value is low, the carbon dioxide in the existing organic waste treatment equipment will increase significantly , leading to the production of a large amount of hydrogen sulfide, and the increase of sulfide content will ...

[0003] Methane bacteria are very sensitive to changes in pH value. It is absolutely necessary to maintain a weak alkaline environment. The optimal pH range of methane bacteria is 6.8-7.5. When the pH value is low, the carbon dioxide in the existing organic waste treatment equipment will increase significantly , leading to the production of a large amount of hydrogen sulfide, and the increase of sulfide content will inhibit the growth of methane bacteria and affect the organic waste treatment speed of existing organic waste treatment equipment. The reaction area between large organic waste and methane bacteria is much smaller than that of small particles of organic waste and methane bacteria, which leads to a decrease in the degradation rate of larger organic waste and reduces the processing efficiency of existing organic waste treatment equipment
