The major equipment comprises a storage bin, a measuring belt, a gathering belt, a screw feeder, a stirrer, a feed screw, an elevator, a feeder, a fermentation tank, a gas reservoir, a biogas outlet tube, a spray tube, a heat exchanger, a spray pump, a discharge screw, a gathering screw, a discharging machine, a recovery screw, a flow-dividing screw, a control system and the like.

Description

A kind of continuous dry fermenting is produced the Processes and apparatus of biogas
Technical field
The invention belongs to energy utilization and field of environment protection, relate to the Processes and apparatus that a kind of continuous dry fermenting is produced biogas.
Background technology
Biogas anaerobic fermentation can be divided into wet type and dry type two big classes.The wet type anaerobically fermenting is mainly used in liquid waste such as feces of livestock and poultry, mud and produces biogas, and factor of created gase is lower, handles bad meeting and causes secondary pollution if produce a large amount of natural ponds liquid, needs the consumption mass energy in cold district enforcements in addition, and economic benefit is relatively poor.And the dry type fermentation technique is used to handle solid organic castoff, when obtaining biogas, produces fertilizer.No matter existing dry type fermentation technique is pot type, cell-type or other modes, the overwhelming majority is a sequence batch (, these modes or input and output material difficulty; Equipment price is expensive, or floor space is big, and the hermatic door manufacturing requires high; Material need repeatedly move the storehouse, and the biogas explosion-proof monitoring requires high.
Summary of the invention
The suite of equipment and the process method that the purpose of this invention is to provide a kind of continous way dry type fermentation; Can utilize the solid organic waste to carry out producing methane through anaerobic fermentation; Its advantage is: occupation of land less, energy consumption is low, input and output material is convenient, can realize accurate measurement and full automatic control.
The present invention produces the Processes and apparatus of biogas for a kind of continuous dry fermenting; Technology is: multiple raw material (feces of livestock and poultry, straw, organic waste etc.) are mixed; Be transported in the fermentor tank; Charging and discharging every day once, discharging has 25～35% to be recovered to stirrer and to mix and be mixed together in the raw material evenly, the percolate in the fermentor tank sprays in the retort after the interchanger heating through spray pump.Major equipment comprises storage bin, measuring belt, the belt that gathers materials, feed screw, stirrer, feed auger, lift, charger, fermentor tank, gas storage holder, biogas escape pipe, shower, interchanger, spray pump, discharging spiral, the spiral that gathers materials, discharging machine, recovery spiral, shunting spiral and system etc.

Embodiment
Be equipped with the storage bin of respective numbers according to the kind of fermentation raw material; With the various fermentation raw materials storage bin 1 of packing into, press the rotating speed of the proportioning adjustment corresponding measurement belt 2 of raw material by shovel loader, various raw materials have just been fallen the belt 3 that gathers materials; Raw material is transported to stirrer 5 through defeated material spiral 4; Raw material through stirrer mixes has been fallen feed auger 6, rises to the charger 8 that is positioned at fermentor tank 9 tops to lift 7 again, by charger 8 raw material is pressed into and carries out anaerobically fermenting in the fermentor tank 9; The biogas of generation goes out pipe 11 outputs by biogas, and the percolate of jar interior raw material is heated to suitable temperature by spray pump 14 extractions through interchanger 13 and sprays in the jar to shower 12, plays the effect of attemperation; Grog after the fermentation is collected discharging spiral 15 by the spiral 16 that gathers materials and is outputed to outside the jar through discharging machine 17; Reclaim the sub-fraction grogs and mix in the virgin material to stirrer 5 and be mixed together by reclaiming spiral 18, unnecessary grog is sent to by shunting spiral 19 and is made fertilizer and process.Whole process can be controlled by automatic control system automatically.
