Abstract
The utility model provides a suction pipeline protector of an immersed type membrane bioreactor, which can effectively ensure the vacuum of the pipeline and enable the immersed type membrane bioreactor to run efficiently, and meanwhile ensure that a suction pump has a low possibility of idle running and that the service life of the suction pump is prolonged. The utility model adopts the technical scheme that the suction pipeline protector comprises the body of the immersed type membrane bioreactor, a transfer pipeline and the suction pump, and is characterized in that a gas-water separation cavity is further included, the body of the immersed type membrane bioreactor is connected with the gas-water separation cavity through the transfer pipeline, the transfer pipeline is arranged obliquely and upwardly, the contact position of the transfer pipeline and the gas-water separation cavity is located at the top of the transfer pipeline, the top of the gas-water separation cavity is communicated with an exhaust pump, and the bottom of the gas-water separation cavity is communicated with the suction pump.
Description
Technical field
The utility model relates to wastewater treatment machinery apparatus field, is specially a kind of aspiration protector of submerged membrane bio-reactor.
Background technology
Existing submerged membrane bio-reactor, easy trapped gas in the aspiration, during the suction pump suction, need pour water or take air in other means escape routes pipeline, guarantee the vacuum tightness of pipeline, caused the fallback of submerged membrane bio-reactor like this, suction pump simultaneously is idle running easily also, causes the working life of suction pump to shorten.
Summary of the invention
At the problems referred to above; the utility model provides a kind of aspiration protector of submerged membrane bio-reactor, and the vacuum tightness that it can effectively guarantee pipeline makes the efficient operation of submerged membrane bio-reactor; suction pump simultaneously also is difficult for idle running, and the working life of suction pump obtains prolonging.
A kind of aspiration protector of submerged membrane bio-reactor; its technical scheme is such: it comprises submerged membrane bio-reactor body; transfer line; suction pump; it is characterized in that: it also comprises the gas-water separation cavity; described submerged membrane bio-reactor body connects described gas-water separation cavity by described transfer line; described transfer line is tilted to layout; the contact position of described transfer line and described gas-water separation cavity is the extreme higher position of described transfer line; the top of described gas-water separation cavity is communicated with off-gas pump, and the bottom of described gas-water separation cavity is communicated with described suction pump.
It is further characterized in that: described transfer line connects the import of described gas-water separation cavity by suction flange, and described import is arranged at the outer wall of described gas-water separation cavity;
The bottom of gas-water separation cavity is a conical head, and described conical head bottom connects described suction pump by reducer union, flange;
The top of described gas-water separation cavity connects escape pipe by discharge flange, and described escape pipe connects the import of described off-gas pump, and described exhaust pump outlet connects outside escape pipe;
Described escape pipe is equipped with gas feed ball valve, magnetic valve;
Described outside escape pipe is equipped with the pneumatic outlet ball valve.
After adopting structure of the present utility model; the extreme higher position of the transfer line of submerged membrane bio-reactor body connects the gas-water separation cavity; because being generally out, the submerged membrane bio-reactor body cycle of operation stopped to be provided with in 2 minutes (the concrete cycle of operation decides according to every submerged membrane bio-reactor) in 7 minutes; in submerged membrane bio-reactor body process out of service; gas in the transfer line separates owing to the density difference with liquid; isolated gas will lead to pipeline protection cavity along being tilted to the transport pipe of arranging; in pipeline protection cavity because gas liquid density difference; its gas liquid natural separation; the top of gas flow pipeline protection cavity; the bottom of flow direction pipeline protection cavity; and pass through off-gas pump respectively; oil suction pump is discharged; it can effectively guarantee the vacuum tightness of pipeline; make the efficient operation of submerged membrane bio-reactor; suction pump simultaneously also is difficult for idle running, and the working life of suction pump obtains prolonging.
