Original title: Precautions and cleaning methods for titanium rod filter Precautions and cleaning methods of titanium rod filter The titanium rod filter adopts 316 L stainless steel material as the shell, and the internal filter element is a titanium tube, which has the characteristics of light weight, high temperature resistance, high pressure resistance, strong acid, strong alkali, corrosion resistance, and the filter element can be regenerated and used repeatedly. It is a hollow filter tube made of titanium metal powder by powder metallurgy without high temperature sintering. It is widely used in the liquid-solid separation of food, beverage, medicine, chemical industry and so on. In the pharmaceutical industry, it is especially suitable for decarburization filtration in the production line of infusion and injection. Titanium rod filter This series of products are compact in structure and beautiful in appearance. They are produced according to GMP standard. The pipe fittings are connected by international standard quick connection, which is convenient for disassembly, titanium bar gr7 , assembly and cleaning. Precautions for use of titanium rod filter 1. Avoid scratch, collision, dust and oil stain. 2. The working pressure shall not exceed the rated working pressure during use. 3. In normal use, there should be at least 3-5 minutes of low-pressure starting time, and the relative pressure difference should be controlled below 0.5Mpa, and then the working pressure should be gradually adjusted to normal requirements (the highest pressure should not exceed 0.4Mpa). 4. After the product runs to a certain period, the filter element may be blocked, resulting in increased pressure and decreased flow, requiring backflushing or backwashing regeneration. The regeneration cycle depends on the rated pressure and flow Clean method of titanium rod filter After the titanium rod filter element is used for a period of time, it will be blocked to a certain extent, showing that the flow decreases and the pressure at the front end of the filter increases, for example, from below 0.22 mPa to above 0.3mPa. At this time, it is necessary to clean the filter element. The cleaning methods are generally as follows: 1. For the newly used filter element, clean water is generally used for backwashing. The cleaning is carried out by the method of gas reverse blowing, that is, clean water slightly higher than the working pressure (such as 0.3mPa) is injected in the reverse direction for cleaning. The backflushing time is about 1 to 3 minutes. 2. When the filtering effect does not rise obviously after several times of backwashing, it can be soaked in hydrochloric acid solution below 5%,Titanium welding pipe, sulfuric acid solution below 8%, or NaoH solution below 10% at room temperature, and then washed with clean water. The specific choice of acid washing or alkali washing should be based on the fact that the impurities in the filtrate are easily soluble in acid or alkali.
