Hydraulic-circulating fermentation process and apparatus

Abstract

The invention relates to a water power circle fermentation process and an apparatus thereof, and the process comprise the following ordinal steps: step (A), the incoming stuffing flows naturally from the discharge port of a dry-type fermentation apparatus into a fermentation cylinder of the apparatus; step (B), the stuffing is pumped from the fermentation cylinder into a heat-exchanging apparatus to be heated through a circle pump, after being heated up, the stuffing returns into the fermentation cylinder through the circle pump for heat preservation and fermentation; step (c), materials in the fermentation cylinder continuously ferment to discharge the marsh gas, pond flotsam and pond liquid through the corresponding port. The apparatus comprises the fermentation cylinder, the heat-exchanging apparatus, an internal membrane, an external membrane, the circle pump, the control system, etc. The heat-exchanging apparatus is arranged outside the fermentation cylinder, and the fermentation cylinder is provided with a marsh gas outlet valve and a bleeder valve, the internal and the external membranes are sequentially arranged on the top of the fermentation cylinder, and a safety valve is arranged at the upper part of the external membrane, and an air cavity is formed between the internal membrane and the external membrane, and a fan and a pipe are communicated with an air charge cavity, and a temperature sensor is arranged under the fermentation cylinder. The control system and the temperature sensor are electrically connected with the heat-exchanging apparatus. The invention is mainly applied in the dry-type fermentation process of crops straw.

Description

1. Technical field [0001] The invention relates to a method and equipment for microbial anaerobic treatment of agricultural waste, animal husbandry waste and industrial waste water, in particular to a hydraulic cycle fermentation process and device. 2. Background technology [0002] At present, anaerobic fermentation methods and equipment mainly include fully stirred anaerobic fermentation process, anaerobic contact process reactor, upflow anaerobic sludge bed reactor and upflow anaerobic solid reactor, etc. These methods and process equipment have the following disadvantages or deficiencies: ①The materials targeted by the equipment are mainly animal husbandry manure. Since the carbon-nitrogen ratio of straw is much higher than the carbon-nitrogen ratio required by anaerobic fermentation itself, it is not yet possible to treat agricultural straw materials. Carry out fermentation treatment; ②Built-in heat exchange is mostly used, the tank body is easy to corrode, poorly seale...

Problems solved by technology

These methods and process equipment have the following disadvantages or deficiencies: ①The materials targeted by the equipment are mainly animal husbandry manure. Since the carbon-nitrogen ratio of straw is much higher than the carbon-nitrogen ratio required by anaerobic fermentation itself, it is not yet possible to treat agricultural straw materials. Carry out fermentation treatment; ②Built-in heat exchange is mostly used, the tank body is easy to corrode, poorly sealed, and easily affected by anaerobic bacteria; ③The equipment is complicated, and the fermentation tank must be equipped with a special gas storage tank, which occupies a large area and has poor operation safety; ④Many supporting facilities, large investment and high operating cost
