Abstract

The present invention discloses a livestock and poultry excrement resource regeneration treatment and municipal sludge pyrohydrolysis device, which comprises a livestock and poultry excrement sludge storage tank, a feeding port is connected to the upper portion of the left end face of the livestock and poultry excrement sludge storage tank, and a centrifugal dehydrator, a stirring tank, a main reaction tank and a flash tank are sequentially installed on the right side of the livestock and poultry excrement sludge storage tank; stirring is conducted through a rotating rod and a stirring rod onthe outer surface of the rotating rod, preheating of the livestock excrement sludge is achieved through heating of a heater; after stirring and preheating, the livestock excrement sludge is pumped outthrough a third material pump and pumped into the main reaction tank through a third connecting pipe, and hot steam enters the main reaction tank through a steam inlet pipe to heat and pressurize thelivestock excrement sludge; and finally, the sludge is conveyed into the flash tank for flash evaporation by utilizing the pressure difference in the main reaction tank and the flash tank, wherein steam generated in the flash tank is returned into the stirring tank to be uniformly mixed with new livestock excrement sludge for heating, so that heat recovery is realized and the sludge subjected topyrohydrolysis is discharged from the discharge pipe. The device is simple to operate, high in treatment efficiency, low in cost and worthy of popularization.

Description

technical field [0001] The invention relates to the technical field of livestock and poultry sludge treatment, in particular to a device and process for regeneration treatment of livestock and poultry waste resources and thermal hydrolysis of urban sludge. Background technique [0002] In China, the rapid development of the livestock and poultry breeding industry has played an important role in the development of the rural economy and the increase of farmers' income. A large amount of excrement will be produced in the livestock and poultry breeding process, especially in large-scale or large-scale farming. It is necessary to carry out harmless treatment or resource utilization of these feces, otherwise it will pollute the environment. [0003] Sludge generated during urban life and the operation and maintenance of urban municipal facilities related to urban life activities. According to the source, it can be divided into sewage plant sludge, water supply plant sludge, drai...
