Application and maintenance of stainless steel sintered filter in petroleum and petrochemical industry

?????? Stainless steel sintered filter can be used not only as filter medium for filter equipment such as basket filter and mesh filter , but also Weifu stainless steel sintered filter has high filtration precision, high temperature resistance, corrosion resistance and high mechanical strength. It has many excellent properties such as easy processing and long life, so it is increasingly applied to the separation of products and process media in the petroleum and petrochemical industry. Metal powder such as stainless steel sintered filter hydroxylamine caprolactam catalyst filter in the production process, and the application of a multi-layer stainless steel wire mesh sintered filter in FCC slurry oil filter have achieved good separation.

In the petroleum and petrochemical industry, although the stainless steel sintered filter element has high mechanical strength and strong corrosion resistance, the filter element is still damaged or broken during use. The damage and breakage of the filter element is mainly due to the fact that the filter element is in the process of regeneration, and the calcination method is generally used in order to remove the catalyst particles causing the plugging of the filter element or the oil slurry remaining on the surface of the filter element. In the roasting process, the local high temperature of the filter element is inevitably caused, and the carrier of the caprolactam hydroxylamine reaction catalyst is activated carbon. At high temperature, carbon will penetrate into the stainless steel material to cause carburization of the material. The carbon content in the stainless steel is greatly increased, which reduces the mechanical properties and corrosion resistance of the stainless steel material. The carburized stainless steel material undergoes alkali embrittlement during further lye regeneration treatment, resulting in a significant decrease in mechanical strength and damage to the filter element upon impact.

?????? In view of the damage of the filter element, the main reason is that the filter element has carburized during the regeneration process, and carburization can occur at high temperature. Therefore, the fundamental method to solve the problem is to avoid roasting during the regeneration process of the filter element. Solution soak or ultrasonic cleaning.

Rice Huller With Polisher

Introduction:
The SB Rice Milling Unit is a kind of comprehensive equipment. Rice goes into machine via vibrating screen (removing stones) and magnet unit (removing little piece of steel), and then pass through hulling room (remove the yellow husks), winnowing room, milling room (remove the brown chaff, and then become white rice), and blowing room in turn. The machine can complete all the processing works from cleaning grain, hulling grain to milling rice. As to husk, chaff, blighted grain, as well as polished rice, they are all pushed out of machine separately. Furthermore, we add a jet blower near the outlet of finished white rice; it not only can drop down the temperature of white rice, but also can separate chaff from the white rice, and make the finished rice much clear.

Feature:
This Rice Huller with Rice Polisher is a comprehensive expression for all the good qualities of varied kinds of rice-processing machines. For instance, it is arranged with a comprehensive view of situation and is designed rationally. Its structure is compact and well organized. It is of less noise and can be easily operated and reliably regulated. Rice after processed consists of less chaff and few of them are damaged (broken). The neatness of such rice may be up to above standard. It consumes less power and is efficient in work. It is indeed Combined Rice Milling of a new generation.
