Problems solved by technology

[0006] For example, the Chinese patent No. ZL200620001726.8 discloses a precision filter, the backflush port is located on the top of the backflush chamber, and during backflush, the air pressure and velocity of the filter tube near the backflush port are relatively high. Large, large impact increases the risk of filter tube leaking, while the filter tube far away from the backflushing port is not completely backflushed due to the low air velocity and pressure

Embodiment Construction

[0028] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0029] What the present invention discloses is a kind of air-water backflushing device for tubular sintered membrane filter, such as Figure 1 to Figure 6 Shown is a preferred embodiment of the present invention. The filter 1 includes a housing, which can be composed of a cylinder body 11 and a cover plate 12 that are covered with each other. A filter tube connecting plate 13 is installed in the housing, and the filter tube connecting plate 13 is provided with a Several installation holes 131, each installation hole 131 is fixedly installed with a sintered film tube 14. The filter tube connection plate 13 divides the inner space of the housing into two chambers, the sewage water inlet chamber 15 and the backflushing chamber 16, the sintered membrane tube 14 is located in the sewage water inlet chamber 15, and the sintered membrane T...

Abstract

The invention discloses an air water reverse blowing and washing device used for a tubular sintered membrane filter. At least one air distribution plate is arranged in a reverse blowing and washing cavity in a shell of the filter, the air distribution plate and a filter pipe connecting plate mounted in the shell are arranged at intervals, a plurality of air distribution holes are formed in the air distribution plate, and the air distribution holes are in one-to-one correspondence and central alignment with a plurality of mounting holes formed the filter pipe connecting plate and used for fixedly mounting a sintered membrane pipe. The added air distributing plate can guide the reversely blown air flow, so that the problems that the reverse blowing and washing is not uniform or complete are solved, and no dead angle exists during reverse blowing and washing.

Description

technical field [0001] The invention relates to the technical field of sewage purification treatment, in particular to an air-water backwash regeneration device for a tubular sintered membrane filter. Background technique [0002] The tubular sintered membrane has the characteristics of large filtration area per unit volume, large filtration flow rate per unit filtration area, high filtration accuracy (up to 0.1 μm), strong anti-fouling ability, high rigidity, strong pressure resistance, and strong backflushing regeneration ability. , Widely used in chemical, food, medical and pharmaceutical, biotechnology, environmental engineering and other industries for sewage purification or other liquid clarification filtration, liquid-solid separation, etc. [0003] Preventing membrane clogging, prolonging the service life of membranes, and reducing treatment costs have always been the goals pursued by the membrane filter industry. Since the sintered tube is rigid, compressed air can...
