Microporous filter membrane separation equipment

Abstract

The invention relates to the technical field of microporous filter membranes, and discloses microporous filter membrane separation equipment which comprises a stainless steel barrel, a first filter element is fixedly mounted on the inner wall of the lower end of the stainless steel barrel, a second filter element is sleeved with the first filter element, a third filter element is sleeved with the second filter element, a partition plate is fixedly mounted at the upper end of the third filter element, a drainage piece is fixedly installed in the middle of the partition plate, the outer wall of the partition plate is fixedly sleeved with a sealing ring, the upper end of the stainless steel barrel is fixedly connected with a pressure gauge, the lower end of the stainless steel barrel is fixedly connected with an air inlet pipe and an air outlet pipe, and the air outlet pipe communicates with the interior of the first filter element. Air enters the stainless steel barrel through the air inlet pipe and enters the air outlet pipe through the first filter element, the second filter element and the third filter element to achieve the filtering purpose, the cleaning frequency can be reduced, abrasion of the surfaces of the filter elements caused by second cleaning is reduced, the service life is prolonged, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of microporous membrane separation, in particular to a microporous membrane separation device. Background technique [0002] Microporous membrane filter is a kind of membrane separation technology. The filter is a cylindrical cylindrical structure made of 304 or 316L stainless steel, with a folded filter element as the filter element, which can filter out particles and particles above 0.1 μm in liquid and gas. bacteria. [0003] When the separation equipment starts to filter gas, the filter element in the equipment is still very clean, so the air pressure in the separation equipment is generally maintained at 0.05-0.1mpa, but after a long period of use, it is necessary to gradually adjust the pressure in the separation equipment to make the equipment It can filter normally, so that the slightly clogged filter element can continue to work, but when the internal pressure of the separation equipment is high, t...

[0003] When the separation equipment starts to filter gas, the filter element in the equipment is still very clean, so the air pressure in the separation equipment is generally maintained at 0.05-0.1mpa, but after a long period of use, it is necessary to gradually adjust the pressure in the separation equipment to make the equipment It can filter normally, so that the slightly clogged filter element can continue to work, but when the internal pressure of the separation equipment is high, the filtration speed slows down a lot, and the filter element needs to be cleaned, so it is extremely troublesome to clean the filter element at intervals, and Reduce the efficiency under filtration, so a microporous membrane separation device is required
