Description

Highly effective high concentration baffling type anaerobic reaction device
Technical field
The utility model relates to a kind of methane gas producing device, and especially a kind of anaerobion is handled the highly effective high concentration baffling type anaerobic reaction device that organic waste produces biogas.
Background technology
Biogas engineering is to adopt the anaerobism technology to carry out innoxious digestion process organic waste, produces a kind of energy environment protection engineering of biogas and high-efficiency organic fertilizer.At present, domestic and international big-and-middle-sized biogas engineering technology has a lot, divides from the type of reactor, has three types of conventional type, mud detention type and adhesive membrane types.Conventional type comprises conventional anaerobic ferment process, complete hybrid anaerobic ferment process and plug flow type anaerobic ferment process (claiming the pulling flow type anaerobic ferment process again).The mud detention type comprises anaerobism contact process, flow lifting type anaerobic ferment process (USR), upflow anaerobic sludge blanket process anaerobic ferment process (UASB), baffling type anaerobic zymotechnique etc.Adhesive membrane type comprises anaerobic filter zymotechnique (AF), fluidized-bed zymotechnique (FBR) and expanded bed zymotechnique (EBR) etc.Wherein, mud detention type and adhesive membrane type anaerobic ferment process mainly are applicable to the organic waste water that feed concentration is low, the suspended substance solids content is few, the construction investment height.The conventional type anaerobic ferment process is suitable for generally that feed concentration is big, the higher organic waste water of suspended substance solids content, investment cost is lower, economic and practical, meet the regional current situation of current domestic major part, long, difficulty big (mainly being antiseepage leakproof work) of engineering time, gas producing efficiency are not high, the final-period management task heavily waits shortcoming but conventional type reaction tank engineering exists, and have limited further and have promoted the use of.
The utility model content
The purpose of this utility model provides the high highly effective high concentration baffling type anaerobic reaction device of a kind of factor of created gase.
The technical solution of the utility model is: a kind of highly effective high concentration baffling type anaerobic reaction device, the slag-drip opening that comprises opening for feed, airway and the bottom on housing and its top, on housing inner top surface and inner bottom surface, be staggeredly equipped with baffle plate, in housing, be provided with stirrer mechanism.
Stirrer mechanism by horizontal rotating shaft, be contained in the blade in the horizontal rotating shaft and the motor that connects with horizontal rotating shaft is formed.
Side at housing is provided with overflow port.
Be covered with the PC hollow sheeting on the top of housing.
Bottom at housing is provided with heating tube.
This device is intended to overcome in the existing conventional anaerobic ferment process congenital defects such as difficulty of construction is big, and factor of created gase is low, and the problems of existence are utilized biogas technology for higher generalization and established solid technical support and assurance in improving that current biogas technology is actual and building.This invention of comprehensive consideration, generalized theory has the following advantages: not only easy construction, simple to operate, different zones different heating mode, the gas producing efficiency height, and can the batch production running, production in enormous quantities, image appearance be attractive in appearance.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Structure of the present utility model is as shown in Figure 1: comprise the slag-drip opening 8 of opening for feed 1, airway 3 and the bottom on housing 11 and its top, be staggeredly equipped with baffle plate 2 on housing inner top surface and inner bottom surface, be provided with stirrer mechanism in housing.Stirrer mechanism by the rotating shaft 12 that laterally runs through housing, be contained in the blade 13 in the horizontal rotating shaft and the motor 7 that connects with horizontal rotating shaft is formed.Be provided with overflow port 6 in the side of housing, be covered with PC hollow sheeting 4 on the top of housing.Be provided with heating tube 9 in the bottom of housing.
Principle of work: reaction unit inside is provided with baffle plate 2 and stirring mechanism, drive blade 13 in the rotating shaft 12 by motor 7 low speed and stir and make that digested sludges (anaerobion) are in suspended state all the time in the housing 11, guarantee microorganism and can biochemistry is organic fully contact.Pending waste liquid enters in the housing by opening for feed 1 from the left end on reaction unit housing top, under baffle plate 2 guide functions, waste liquid is gone up current downflow repeatedly, through the stirring at low speed of stirring mechanism, with the digested sludge thorough mixing, and prevent that reactor inner suspension thing crust and mud from precipitating for a long time.Anaerobion in the mud decompose in the digestion waste liquid can biochemical organism, produce a large amount of biogas, constantly discharge with the micro-bubble form, discharge through the top duct airway 3 of housing.Liquid natural pond, natural pond slag after the processing flows out automatically from the lateral overflow port 6 of housing right-hand member.In addition, at different regions, can take the heating tube 9 of different modes by housing bottom to heat, such as utilizing heating such as stalk or boiler afterheat to reaction unit.
The innovation explanation: this reaction unit is provided with automatization feeding unit (prior art), and is simple to operate, easy to use.Reaction unit is arranged PC sun power hollow sheeting outward, has characteristics such as transparency height, light weight, good heat-insulation effect, and reactor is remained in the suitable leavening temperature, and gas producing efficiency improves greatly.Reaction unit adopts high heat absorption black coating film layer steel plate materials, and inside and outside solar absorptance reaches more than 80% through the antirust processing of multi-layer anticorrosion, and heat-transfer effect is good.Need not to be provided with pretreatment pool and water pressure house, discharging flows into feace storing pool by overflow port.Device characteristic:
1, large-scale industrialized moulding production, the engineering time shortens greatly;
2, solar heating, the insulation of PC hollow sheeting, fermentation efficiency height;
3, establish stirring mechanism in, feed liquid is mixed fully, anti-crust, precipitation, and have the plug-flow effect;
4, baffle plate water conservancy diversion prolongs MRT, and factor of created gase improves 30%-50%;
5, the different heating mode can be taked in different regions, as stalk heating or boiler afterheat heating;
6, reaction unit ground type or half ground type entirely, outside image is good;
7, simple to operate, easily realize automatization, final-period management is convenient.
Compare with technologies such as UASB, IC, output investment ratio is lower, anti-organic loading ability height; Compare factor of created gase height, convenient management with anaerobic ferment process such as hybrid fully, pulling flow types; It is short that reaction unit starts working time, and treatment capacity is big, does not have the sludge blockage problem.
