Description

Self-air-quantity-balancing function non-blocking perforated aeration pipe and using method thereof

Technical Field

The invention relates to the technical field of gas aeration, in particular to a self-air-quantity-balancing function non-clogging perforated aeration pipe and a using method thereof. The device is mainly applied to the sewage treatment aeration and membrane washing process, and can realize the aeration of sewage and the back flushing of the membrane through the arrangement of the perforated aeration pipe at different positions of different tank bodies, and simultaneously, the perforated aeration pipe can be unblocked all the year round and can be normally used.

Background

Common perforated aeration pipes are largely used in aeration and membrane backflushing processes, but the perforated aeration pipes are easy to enter sludge due to various reasons, the entered sludge cannot be discharged, particularly, when a fan is switched from air supply to air stop, the sludge and a biological membrane flow back, and partial holes are blocked, so that aeration is influenced, uneven aeration is caused, water in a liquid pool needs to be drained for maintenance in order to ensure normal aeration, the original process is interrupted, and a large amount of personnel is needed for maintenance and cleaning; therefore, a novel perforated aeration pipe with a self-cleaning function is needed, sludge in the perforated pipe can be automatically discharged under the condition that the liquid tank does not discharge water and in normal operation, and the perforated aeration pipe is ensured not to be blocked, namely the perforated aeration pipe with the non-blocking function is ensured; thereby ensuring that the aeration can normally operate all the year round and saving a large amount of operation and maintenance cost.

In the common perforated aeration pipe, because the aeration quantity is distributed from the main pipe to the branch perforated aeration pipes unevenly in the aeration process, the phenomenon of uneven aeration exists, and therefore, the uniform aeration can be kept in each perforated aeration pipe system under the condition of insufficient and uneven aeration, namely, the perforated aeration pipe has the function of self-balancing air quantity.

Disclosure of Invention

The invention aims to: the self-balancing air flow function non-blocking perforated aerator pipe has the advantages of reasonable structural design, safety, convenience in operation and use, low maintenance cost, high automation intelligent degree and the like, can realize automatic cleaning and air flow adjustment, can be normally maintained without emptying liquid, and can be normally used in the environment with aeration requirements.

In order to solve the problems in the background art and achieve the purpose, the invention adopts the following technical scheme:

the invention mainly aims to solve the problem that the perforated pipe can be cleaned and cleaned without draining liquid in a liquid pool; namely, the non-clogging perforated aeration pipe can be used throughout the year.

Furthermore, the self-air-quantity-balancing function non-blocking perforated aerator pipe is arranged in a liquid pool, and is supported by a side air inlet vertical pipe, a bottom perforated pipe and a side blow-off pipe, and the inlet and the outlet of the fixed perforated aerator pipe are all arranged on the surface of the liquid pool; a drain valve and a drain outlet are arranged at the outlet on the liquid pool; the air inlet bent pipe, the air inlet valve and the air inlet main pipe which can be quickly disassembled and assembled are arranged at the water inlet; the configuration is mainly that the tail end of the perforated pipe is extended to expose the pool surface from the pool bottom, an inlet and outlet valve is added, and mud and sewage are discharged from the tail end through manual or automatic control; strongly cleaning the perforated pipe hole by increasing air flow instantaneously to clean the blocked hole; the problem of need not the liquid in the evacuation liquid pond can wash and clear up the stifled hole of perforated pipe is solved.

Furthermore, the self-air-quantity-balancing function non-blocking perforated aeration pipe has the advantages that when the aeration is initially operated or is stopped for a certain time from the new operation, air enters the perforated aeration pipe through the branch of the air inlet main pipe and the air inlet valve, sludge and dirt of the perforated pipe are completely discharged through the drain outlet when the perforated pipe passes through the opened drain valve, and the lower exhaust hole, the middle exhaust hole and the upper exhaust hole of the perforated pipe are completely dredged through the air hammer phenomenon when the drain valve is quickly closed; the invention relates to a self-air-quantity-balancing function non-clogging perforated aerator pipe, which mainly aims to solve the problem that the clogging can be cleaned without emptying liquid in a liquid pool.
