Straw hydrolytic acidification pre-treatment reaction device

Abstract

The invention discloses a straw hydrolytic acidification pre-treatment reaction device. The straw hydrolytic acidification pre-treatment reaction device comprises a temperature control system, a stirring system, a feeding system, a discharging system, an aeration system, an overflowing system and a monitoring feedback system, wherein the inner part of the reaction device is a reverse tapered tankbottom; the center of the tank bottom is downward connected with a discharging pipeline and an aeration ventilation pipe; an upper end opening of the discharging pipeline is connected with a discharging motor through a motor bracket; the discharging pipeline is provided with a valve; after straw hydrolytic acidification pre-treatment reaction is finished, material liquid is sufficiently dischargedout of a tank body through the discharging motor communicated with the reverse tapered bottom, and a mixture of hydrolytic dreg and hydrolysate is filtered through a filtering strainer, so that solids and liquid are separated; the solid hydrolytic dreg is remained in the filtering strainer and the hydrolysate flows into a hydrolysate collection tank. By adopting the straw hydrolytic acidificationpre-treatment reaction device, the problems of a straw hydrolytic acidification pre-treatment process of crusting and non-uniform aeration are solved; the straw hydrolytic acidification pre-treatmentreaction device has the advantages of capability of continuously feeding and discharging materials, stable parameter control and low operation energy consumption, and has a wide application prospect.

Description

technical field [0001] The invention relates to the technical field of biogas engineering hydrolysis and acidification pretreatment, in particular to an inverted cone hydrolysis and acidification pretreatment reaction device for continuous feeding and discharging of high-concentration full fermentation. Background technique [0002] For all biological processes, it is very important to maintain the stability of the biological growth environment. The metabolic process of anaerobic microorganisms is affected by many factors, such as temperature, pH, redox potential, nutrients, trace elements, specific surface area of ​​raw materials, etc. Therefore, in order to provide a suitable fermentation environment for microorganisms, the influence of these factors must be fully considered and controlled according to the needs of microorganisms. In addition, the difference between the environmental requirements of fermentative bacteria such as hydrolytic bacteria and acidogenic bacteria...
