Description
Technical field
The present invention relates to a kind of fermentor tank discharge system, particularly relate to a kind of marsh-gas fermentation tank double hose overflow system.
Background technology
At present; the big-and-middle-sized biogas engineering of domestic and international mass-producing is increasing; most of biogas engineering adopts ground type marsh-gas fermentation tank; but marsh-gas fermentation tank discharge system is all adopt single tube from overflow system; the operation scheme of discharging after first charging; and do not realize automatically controlling, cause the active sludge in tank to run off serious, affect biogas fermentation efficiency.
Summary of the invention
For above-mentioned prior art Problems existing, the object of the invention is to provide one to solve above problem, adopts the marsh-gas fermentation tank double hose overflow system of the operation scheme of first discharging rear feeding.
Technical scheme of the present invention is: a kind of marsh-gas fermentation tank double hose overflow system, comprise marsh-gas fermentation tank, upflow tube, overflow device, pipe support, the overflow port institute of described upflow tube is at one end downward-sloping, and be communicated with marsh-gas fermentation tank, the other end of upflow tube is communicated with overflow device, be provided with natural pond liquid pipe a and natural pond liquid pipe b bottom described overflow device, the natural pond liquid entrance of described natural pond liquid pipe a, lower than the natural pond liquid entrance of natural pond liquid pipe b, described natural pond liquid pipe a is provided with gate valve and motorized valve; Adopt twin-tube type structure, when motorized valve breaks down or needs repairing on the liquid pipe a of natural pond, also get rid of natural pond liquid in time by natural pond liquid pipe b;
As preferably, described natural pond liquid pipe a is near marsh-gas fermentation tank, and described natural pond liquid pipe b, away from marsh-gas fermentation tank, is conducive to natural pond liquid and preferentially enters natural pond liquid pipe a;
As preferably, the baffled and open type air guide port in described overflow device top, baffle plate is conducive to preventing rainwater or other animalcules from entering overflow device, results in blockage, and open type air guide port is used for preventing fermentor tank from caving in and breaks;
As preferably, described overflow port is apart from 450mm bottom overflow device, and in overflow device, the discrepancy in elevation of two natural pond liquid pipes is 200mm, is conducive to keeping marsh-gas fermentation tank internal pressure constant;
As preferably, the slanted angle between described upflow tube is communicated with marsh-gas fermentation tank is 40 °, effectively reduces the resistance of ducting, is conducive to natural pond liquid and enters overflow device;
As preferably, also comprise time switch, described time switch is electrically connected with gate valve and motorized valve, controls the unlatching of motorized valve by time switch, first gets rid of natural pond liquid, then enters raw material, is conducive to keeping the mud in marsh-gas fermentation tank.
The invention has the beneficial effects as follows: the present invention adopts the operation scheme of first discharging rear feeding, this device can active sludge in effectively catching tank, improves fermentation efficiency.When motorized valve breaks down or need repairing, also get rid of natural pond liquid in time by another root backup line, especially can prevent line clogging, get rid of natural pond liquid according to sequential control, be conducive to the active sludge retained in marsh-gas fermentation tank, improve fermentation efficiency.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention.
In figure: 1. upflow tube; 2. overflow device; 3. open type air guide port; 4. baffle plate; 5. natural pond liquid pipe a; 6. natural pond liquid pipe b; 7. gate valve; 8. motorized valve.
Embodiment
Embodiment: as one embodiment of the present invention, a kind of marsh-gas fermentation tank double hose overflow system as shown in Figure 1, comprise fermentor tank, upflow tube 1, overflow device 2, pipe support, the overflow port institute of described upflow tube 1 is at one end downward-sloping, and be communicated with fermentor tank, the other end of upflow tube 1 is communicated with overflow device 2, natural pond liquid pipe a5 and natural pond liquid pipe b6 is provided with bottom described overflow device 2, the natural pond liquid entrance of described natural pond liquid pipe a5, lower than the natural pond liquid entrance of natural pond liquid pipe b6, described natural pond liquid pipe a5 is provided with gate valve 7 and motorized valve 8.
When the natural pond liquid in marsh-gas fermentation tank flow in overflow device 2 by upflow tube 1, natural pond liquid flows through gate valve 7 along natural pond liquid pipe a5, gate valve 7 is in normally open, now motorized valve 8 is in closing condition, when then liquid liquid level in natural pond rises to Ye Guanb6 top, natural pond, opened by time control setting motorized valve 8, natural pond liquid flows into the external world through motorized valve 8.After a discharging completes, closed by time control setting motorized valve 8, marsh-gas fermentation tank charging, after charging completes, through certain fermentation time, then carries out discharging next time, so circulates.
When motorized valve 8 needs repairing, closing gate valve 7, natural pond liquid liquid level can rise to Ye Guanb6 top, natural pond, then is flowed into extraneous by natural pond liquid pipe b6.Overflow device top is provided with open type air guide port 3 and baffle plate 4, and open type air guide port 3 breaks for preventing fermentor tank from caving in, and baffle plate 4 is conducive to preventing rainwater or other animalcules from entering overflow device, results in blockage.Whole overflow system is supported by pipe support, is fixedly connected with fermentor tank by pipe support.
Above exhaustive presentation is carried out to a kind of marsh-gas fermentation tank double hose overflow system provided by the present invention, apply specific case herein to set forth principle of the present invention and embodiment, the explanation of above embodiment just understands method of the present invention and core concept thereof for helping; Simultaneously, for one of ordinary skill in the art, according to thought of the present invention, all will change in specific embodiments and applications, to change of the present invention and improve will be possible, and design and the scope of accessory claim defined can not be exceeded, in sum, this description should not be construed as limitation of the present invention.
