Specific embodiment
The utility model is described in further detail below in conjunction with Figure of description and specific embodiment.
As shown in Figure 1, the digestion methane-production-pool device stirring pipe automatic dredging and apparatus for eliminating sludge of the present embodiment, including water pump 1 and pressure
Force detector 2, the outlet of water pump 1 are connected by the first pipeline 31 with stirring pipe 4, and import passes through the second pipeline 32 and digester 5
Connection, the first pipeline 31 is in parallel with the biogas air inlet pipe 6 of stirring pipe 4, and pressure detector 2 is set in biogas air inlet pipe 6.Biogas into
Tracheae 6 is connected with biogas air source (Marsh gas compression machine).
In concrete application example, pressure detector 2 can carry control system, and can also be separately provided can receive pressure
The control system of 2 signal of detector.In the present embodiment, the connection of pressure detector 2 one can be controlled according to the signal of pressure detector 2
The control unit that water pump 1 opens and closes (shown in Fig. 2).Control unit also controls opening and the closing of biogas air source.
When stirring pipe 4 normally stirs, the opening of biogas air source, water pump 1 is closed, and biogas air inlet pipe 6 is persistently logical to stirring pipe 4
Gas, stirring pipe 4 are stirred continuously in digester 5；It, will when pressure detector 2 detects 4 pressure of stirring pipe higher than setting pressure
Signal feeds back to control unit, and control unit control biogas air source is closed, and start water pump 1, and water pump 1 is by containing in digester 5
The digestive juice for having particle silt is pumped into stirring pipe 4, and stirring pipe 4 is rinsed, and particle silt can be managed with stirring pipe 4 in digestive juice
Wall does not stop to collide, and tube wall incrustation is made to come off, and plays the effect of scale removal；After pressure recovery to normal pressure, control unit control
Water pump 1 is closed, and stops rinsing, and start biogas air source, and biogas stirring restores.Control process is as shown in Figure 2.
The digestion methane-production-pool device stirring pipe automatic dredging and apparatus for eliminating sludge of the utility model, successfully solve biogas stirring pipe 4
In the process of running, the problem of difficult and scale removal is difficult is dredged when blocking, realizes auto-flushing, it is time saving and energy saving；It can supervise in real time
4 situation of biogas stirring pipe is controlled, the blocking of stirring pipe 4 causes immediately automatically start during pressure anomaly, and pressure recovery is normal after dredging
Automatic cut-off system is run；Water pump 1 has saved industrial water, no by extracting the digestive juice containing particle silt in digester 5
Increase load to digester 5, it is often more important that can play the role of giving stirring pipe 4 scale removal.
In the present embodiment, the first pipeline 31 is equipped with flushing valve 7.By exporting setting flushing valve 7, punching in water pump 1
It washes valve 7 to open, water pump 1 starts, double control, increases security of system, flushing valve 7 is solenoid valve, also by control unit
Control is opened and is closed.Similarly, biogas air inlet pipe 6 is equipped with biogas valve 8, and biogas valve 8 is solenoid valve, also by control unit
Control is opened and is closed.
In the present embodiment, water pump 1 is booster pump, and high pressure is exported by booster pump, to carrying out high pressure washing to stirring pipe 4,
Can easily, Quick dredging and scale removal, further, freq uency conversion supercharging pump.It, can be according to blocking by carrying out frequency control to water pump 1
Situation automatically adjusts pump discharge pressure, not more than 4 highest proof pressure of stirring pipe.
Operation principle：
Pressure detector 2 monitor in real time biogas stirring operation when pressure, because biogas stir run when its pressure be it is constant,
When pressure detector 2 detects pressure anomaly raising (higher than setting value) in stirring pipe 4, show that stirring pipe 4 may start
It now blocks, control unit closes biogas valve 8, opens flushing valve 7, starts water pump 1, stirring pipe 4 is rinsed, because rinsing
Water pressure is more than biogas and stirs pressure, and the rapidly flow with particle silt can wash away 4 wall of stirring pipe well
Effect can just dredge stirring pipe 4, and remove tube wall incrustation in the general short time；Pressure declines after stirring pipe 4 is dredged, at this point,
Control flushing valve 7 is closed, and water pump 1 is out of service, and 8 unlatchings of biogas valve, digestion methane-production-pool device stirring system restores normal fortune
Row.
Because 4 quantity of stirring pipe of digester 5 is more, therefore need that pressure is installed in each stirring pipe 4 in practical applications
Detector 2, flushing water supervisor's point multiple branch pipes, each branch pipe are connected to stirring pipe 4, each branch pipe be designed with flushing valve 7 with
It realizes that each stirring pipe 4 can be individually rinsed normally to stir without influencing other stirring pipes 4.In addition, this automatic dredging and removing
Timing can be rinsed and combined with condition flushing, i.e., device can start daily in the set time when running control by dirty device
All stirring pipes 4 are carried out with the flushing of once fixed duration, at the same as when certain 4 pressure of root stirring pipe is more than setting value system also can
Start, it is rinsed, to ensure that stirring pipe 4 is unimpeded.
Although the utility model has been disclosed with preferred embodiment as above, it is not limited to the utility model.It is any
Those skilled in the art, in the case where not departing from technical solutions of the utility model range, all using the disclosure above
Technology contents technical solutions of the utility model are made with many possible changes and modifications or is revised as the equivalent of equivalent variations
Embodiment.Therefore, every content without departing from technical solutions of the utility model, according to the utility model technical spirit to above real
Any simple modifications, equivalents, and modifications that example is done are applied, should all be fallen in the range of technical solutions of the utility model protection.
