Description
Technical field
The invention belongs to marsh-gas generating equipment, more particularly to a kind of CSTR anaerobic fermentation tanks.
Background technology
Chinese Methane Resources enrich, and the market demand is huge.2005, main about 600,000,000 tons of the stalk yield of China had 300,000,000 tons of agricultural crop straws to be used as the energy, converts into 1.5 hundred million tons of standard coals.Expect Chinese Primary Crop Straw yield in 2015 and be up to 900,000,000 tons or so, wherein about half can be used as the raw material of agro-ecology mass-energy.The year two thousand twenty, Chinese biogas development amount is up to 270 billion cubic meters, is as many as 4 times in 2000, and annual growth is 9.1%, substantially exceeds fossil fuel（Coal, oil gas）Growth rate, equivalent to 21,220,000 tons of tandard coal amounts, that is, about 30,000,000 tons of quantity of raw coal.One complete biogas fermentation engineering, no matter its scale, all include following technological process：The collection of raw material, pretreatment, installation for fermenting (methane-generating pit), the post processing of discharging and the purification of biogas and storage etc., at present, fermentation raw material mixes fermentation raw material with water in pretreating process, then conveys into ferment tank production biogas.Need to discharge waste material from installation for fermenting after the completion of fermentation, because waste material has certain viscosity, therefore waste material is difficult discharge and waste material and can usually stick in device inwall.
The content of the invention
Problem to be solved by this invention is to overcome the deficiencies in the prior art, there is provided a kind of CSTR anaerobic fermentation tanks.
The present invention solves its technical problem and takes following technical scheme to realize：
A kind of CSTR anaerobic fermentation tanks, including tank body, agitating device, it is characterised in that：The tank body uses enamel assembling tank, enamel sheet is titanium alloy plate, and two to three layers of enamel coating are coated on the inside and outside two sides of steel plate, and the outer wall of tank body is provided with heat-insulation layer, and zone of heating is provided between tank wall and heat-insulation layer, it is provided with heater strip in zone of heating；Tank body top is provided with gas outlet；Tank body bottom is provided with discharging opening；Tank body top is provided with charging aperture；Tank interior is provided with agitating device.
Further, the agitating device includes fire-proof motor, fire-proof motor and coupled reductor are arranged in frame, frame is arranged on chassis, reductor is connected by shaft coupling with the drive shaft through chassis, drive shaft is connected with agitating shaft below to drive the agitating shaft with blade to rotate, and the mechanical sealing base sealed at chassis to drive shaft is provided with below chassis.
Further, pressure sensor and temperature sensor are additionally provided with tank body.
Further, the discharge outlet is provided with dewatering type propeller, after the completion of fermentation, by the agitation of propeller, quickly waste material can be discharged from tank body.
The present invention has significant advantage and beneficial effect compared with prior art：Mixing effect is good, efficiency high, economical and practical, while quickly waste material can be discharged from tank body.
