Abstract
The utility model discloses a low-energy-consumption high-efficiency circulating device of an anaerobic reactor, which belongs to sewage treatment equipment, in particular to the peripheral device of the anaerobic reactor, and consists of a low-speed propelling impeller, a transmission motor, a circulating pipe and valves. The water inlet at the upper end of the circulating pipe is connected with a tank body below the three-phase separator of an anaerobic reactor, the water outlet at the lower end of the circulating pipe is connected with the tank body above a water distributor on the bottom of the anaerobic reactor, the low-speed propelling impeller is arranged in front of the water outlet on the lower end of the circulating pipe and is connected with the transmission motor, and the front end and the rear end of the low-speed propelling impeller are both connected with the valves. When the utility model is used, the transmission motor drives the propelling impeller to rotate at a low speed so as to absorb mixed solution in the upper part into the circulating pipe and to push out the mixed solution from the lower part, thereby forming the large circulation, fully mixing the anaerobic granular sludge mixture in the reactor, effectively solving the problem of local dead zones in the reactor, and improving the treatment efficiency. Moreover, as the impeller rotates at a low speed and the energy consumption is low, the utility model can not break up the granular sludge in the anaerobic reactor, and the power consumption is far lower than the power consumption of the power cycle of the ordinary external pump.
Description
Technical field
The utility model belongs to sewage disposal device, is meant a kind of low energy efficient circulation device that is used for anaerobic reactor.
Background technology
Anaerobic reactor is under anaerobic state, utilizes a class facility of biological treatment waste water, as up flow anaerobic sludge blanket reactor (UASB), anaerobic expanded granular sludge bed reactor (EGSB) and internal-circulation anaerobic reactor (IC).
In order to eliminate the local dead band that anaerobic reactor is in operation, usually adopt internal recycle and/or external circulating device, a kind of " circular granular sludge reactor " disclosed as Chinese patent 200720020182.4, it is except that being provided with in reactor the inner circulating tube, also the external reflux pipe is set and is communicated with the formation external circulating device with the bottom water inlet pipe in the reactor outside top, but because the outer circulation pipeline directly is connected with water inlet pipe, if do not strengthen the impact dynamics of water inlet, the dead angle area of reactor corner still can not get thorough solution, if the water inlet surging force strengthens, can break up the granule sludge in the anaerobic reactor again, influence the anaerobic treatment effect.
Summary of the invention
The utility model is just in order to overcome above-mentioned deficiency, a kind of low energy efficient circulation device is provided, and anaerobic grain sludge mixed solution in its energy thorough mixing reactor effectively solves local dead-time problem in the reactor, and have the efficient characteristics of low energy, and can not break up reactor endoparticle mud.Main innovation is that this circulation device of peripheral hardware advances blade and driving motor, circulation tube and supporting valve to form by the slow speed of revolution, circulation tube upper end water-in is connected on the tank body of anaerobic reactor triphase separator below, the lower end water outlet is connected on the tank body of water distributor top, anaerobic reactor bottom, drive propelling blade low speed rotation by driving motor, the top mixed solution is sucked circulation tube, release from the bottom, form systemic circulation.
Specifically implement like this: anaerobic reactor low energy efficient circulation device, external device for anaerobic reactor, it is characterized in that advancing blade and driving motor, circulation tube and valve to form by the slow speed of revolution, circulation tube upper end water-in is connected on the tank body of anaerobic reactor triphase separator below, the lower end water outlet is connected on the tank body of water distributor top, anaerobic reactor bottom, be provided with a slow speed of revolution before the water outlet of circulation tube lower end and advance blade, the described slow speed of revolution advances blade to connect driving motor, and the slow speed of revolution advances the front and back end of blade all to be equipped with valve.Circulation tube top water inlet position is located at anaerobic reactor triphase separator bottom, advancing under the blade effect, in the anaerobic reactor material mud mixed liquid sucked, release from the circulation tube bottom, circulation tube lower end water outlet is located at the above position of water distributor, anaerobic reactor bottom, generally be not more than 2.0m from end height, the mixture thorough mixing stirs in the granule sludge mixture of release and the anaerobic reactor.
Blade is by the external motor transmission in this device, and the blade velocity of rotation is not more than 120 rev/mins, to prevent to break up the granule sludge in the reactor.
The utility model is at anaerobic reactor outer setting two covers or this circulation device more than two covers, and the slow speed of revolution advances under the blade effect in the device circulation tube, makes the interior mud mixed liquid of reactor form systemic circulation.
The utility model advantage is:
1, circulation device top water inlet, the bottom water outlet, thorough mixing anaerobic reactor endoparticle mud mixed liquid is avoided the formation in mud dead band in the reactor;
2, the slow speed of revolution advances blade, promote can not break up in the working cycle granule sludge in the reactor, and energy consumption is very low;
3, circulation line is very short, and the drag losses in the pipeline is much smaller than general water pump outer loop.
