Titanium powder sintered filter element, generally used for coarse filtration or intermediate filtration.This filter element has the advantages of high precision, high temperature resistance, corrosion resistance, high mechanical strength, widely used in the pharmaceutical industry, the shell material is 316L or 304 stainless steel.
Filter for titanium powder sintered filter, high temperature, high pressure resistance, strong acid, strong alkali, corrosion resistance, filter can be used repeatedly renewable characteristics, are the powder metallurgy method divided the titanium powder through high heat sintering hollow filter tubes made of the methods of processing, it is widely used in food, beverage, pharmaceutical, chemical and other industries of liquid-solid separation, especially in the pharmaceutical industry for large decarburization filtration of infusion and injection production line.
1. Avoid scratches, dust and oil.
2. The working pressure should not exceed the rated working pressure.
3. In normal use, there should be at least 3-5 minutes of low-pressure start time, and the relative pressure difference should be controlled below 0.5mpa, and then the working pressure should be gradually adjusted to the normal demand (the highest pressure should not exceed 0.4mpa).
4. after the product runs for a certain period, the filter element may be blocked, resulting in the increase of pressure and the decrease of flow, which requires recoil or backwash regeneration.The regeneration period depends on the rated pressure and flow rate.
After the titanium rod filter element is used for a period of time, there will be a certain degree of blockage, showing reduced flow and increased pressure at the front end of the filter.
1. For the newly used filter element, the method of water recoil and gas back blowing is generally adopted for cleaning, that is, slightly more than the working pressure (e.g.0.3mPa) of clean water to the opposite direction of water cleaning.The recoil time is about 1-3 minutes.
2. When the filtration effect does not improve significantly after repeated backwashing, 5% or less of hydrochloric acid solution, 8% or less of sulfuric acid solution, or 10% or less of NaoH solution can be soaked at room temperature, and then washed with clear water.
The specific choice to use acid or alkali washing, should look at the filtrate impurities easily soluble in acid or base to choose.
