In the petroleum and petrochemical industry, because the stainless steel sintering filter with high filtration precision, high temperature resistant, corrosion resistance, high mechanical strength and easy processing, long life and many other excellent performance, so more and more to the field of the separation of product and process medium.

Such as stainless steel metal powder sintered filter in the process of caprolactam production hydroxylamine catalyst filter in the reaction, and stainless steel multi-layer sintered metal screen filter application in catalytic cracking slurry oil filter has achieved good separation effect.

Although stainless steel sintering filter has high mechanical strength and strong corrosion resistance, but in the use process still filter broken happened.


stainless steel sintering filter not only can be used as a basket strainer, mesh filter filtration equipment such as filter medium, and because the stainless steel sintering filter with high filtration precision, high temperature resistant, corrosion resistance, high mechanical strength and easy processing, long life and many other excellent performance, so more and more applied to the petroleum and petrochemical industry in the field of the separation of products and processes in the media.

Such as stainless steel metal powder sintered filter in the process of caprolactam production hydroxylamine catalyst filter in the reaction, and stainless steel multi-layer sintered metal screen filter application in catalytic cracking slurry oil filter has achieved good separation effect.


in the petroleum and petrochemical industry while sintered stainless steel filter has high mechanical strength and strong corrosion resistance, but still occurs in the course of application of the filter core damage and fracture.

Damage to the filter element, the fracture is mainly due to the filter in the regeneration process, in order to remove lead to filter clogging of catalyst particles or residue on the surface of the filter element, slurry and generally adopt the method of roasting.

Local high temperature roasting process inevitably cause filter, and caprolactam hydroxylamine reaction on the catalyst is activated carbon, carbon at high temperatures will penetrate into the stainless steel material, result in carburizing of materials.

Stainless steel in the carbon content increased significantly, reduce the mechanical properties and corrosion resistance of stainless steel materials.

After carburizing of stainless steel materials in the further alkali treatment on the alkali fragile, result in mechanical strength decreased obviously, filter damage when hit.


given filter the cause of the damage is mainly due to the filter in the process of regeneration of carburizing, carburizing is to occur at high temperature, so the fundamental solution is to avoid filter regeneration process of roasting, can choose or ultrasonic cleaning solution.

Filtration mechanism ?? The liquid flows from the filter element to the outside of the bag, and the filtered particles are trapped in the bag, so that the working principle of bag filtration is pressure filtration. The whole bag filter system consists of three parts: filter container, support basket and filter element. ?? The liquid to be filtered is injected from the top of the water treatment filter element supported by the supporting mesh basket, which makes the liquid evenly distributed on the filtering surface, so that the flow distribution throughout the medium is consistent, and there is no negative effect of turbulence. The liquid flows from the filter element to the outside of the bag, and the filtered particles are trapped in the bag, so that the filtered liquid will not be polluted when the filter element is replaced. The handle design inside the filter element makes filter replacement quick and easy. The characteristics are as follows: ??? High flow capacity; ?? Longer service life of the filter element; ?? The uniform flowing liquid makes the particles and impurities evenly distributed in the filter layer of the filter element; Higher filtration efficiency and lower cost. 1. Selection of filter material? ? First, find out the available filter material according to the chemical name of the fluid to be filtered, according to the chemical combination taboo, and then according to its operating temperature, operating pressure, pH value, operating conditions (for example, whether it needs to be tolerated? Steam, hot water or chemical sterilization, etc.), evaluate one by one, and reject inappropriate filter media. Use is also an important consideration. For example, the filter material used for drugs, food or cosmetics must be FDA-approved; ultrapure water must be pure, and the filter material that does not contain emissions that will affect the specific impedance; filter gas must be Pick a hydrophobic material and whether you need a 'sanitary filter' design, etc. 2. Filtration precision? This is a troubling question. For example, to remove particles visible to the naked eye, use a 25-micron filter; to remove clouds in liquids, use a 1 or 5-micron filter; to filter out smaller bacteria, a 0.2-micron filter is required. The problem is that there are two filter precision units: absolute precision/nominal precision.
