Micro-filtration butt joint membrane assembly

Abstract

The invention discloses a micro-filtration butt joint membrane assembly, which specifically comprises an inlet pipe, wherein the inlet pipe is provided with a bent pipe liquid inlet pipe and an inner pipe cavity is arranged inside the inlet pipe; an outer discharge butt joint pipe provided with a butt joint bent pipe and a micro-filtration assembly arranged in the outer discharge butt joint pipe, wherein the inlet pipe is connected with the outer discharge butt joint pipe through a butt joint connecting piece, an inner communicating pipe is arranged at the position, located in the butt joint connecting piece, of the inlet pipe, and an outer communicating pipe is arranged at the position, located in the butt joint connecting piece, of the outer discharge butt joint pipe; and a hemispherical arc-shaped plate is arranged at one end, located at the butt joint connecting piece, of the interior of the outer discharge butt joint pipe. The invention relates to the technical field of microfiltration membrane application. According to the micro-filtration butt-joint membrane assembly, the hemispherical arc-shaped plates are arranged in the micro-filtration butt-joint membrane assembly and are mainly used for buffering and isolating water flow injected into the micro-filtration butt-joint membrane assembly, the impact of the water flow is reduced through backflow convection, and after the internal water flow is subjected to backflow circulation for multiple times, the water flow can be ensured to be stable when being injected into the filter element.

Description

technical field [0001] The invention relates to the technical field of microfiltration membrane applications, in particular to a microfiltration butt joint membrane module. Background technique [0002] Polyethylene sintered tube microporous filters have been available in the 1960s and 1970s. The pore diameter of the microporous tube is relatively large. Its filtration accuracy is separated by deep filtration, that is, the retention of curved capillary pores. The pore size is Symmetrical and therefore prone to clogging. The structure of the filter is mostly a single cylinder type. Due to the limitations of its structure, it is mostly manual operation. The hollow fiber ultrafiltration microfiltration membrane module has been widely used in water purification, sewage turbidity removal, reverse osmosis front-end pretreatment, liquid substances ( In the field of separation and purification, fractional purification and concentration of solution), the membrane module contains sev...
