Embodiment 1

[0030] Example 1: Take 1.000 kg of stainless steel 316L powder with a particle size of 30 to 100 mesh, add 0.1% to 20% of forming agent, mix it in the mixing equipment for 1 to 3 hours, and take it out. The mixing equipment is V-shaped mixing equipment, double cone mixer feeder or ball mill, and then through the casting machine to obtain powder tubes and sheet green embryos, degrease treatment in a vacuum furnace at a temperature of 300-600 ° C, and then apply 40 mesh 316L stainless steel mesh on the powder tubes and sheet green embryos, put into a vacuum furnace and sintered at 1000-1600°C to obtain a powder tube, sheet support layer and composite support layer containing a strengthening phase and a certain porosity; after the support layer is cooled and taken out, use electrostatic spraying or ordinary spraying Spray coating with 200-600 mesh, control the thickness of the coating to 0.1-0.5mm, and then sinter at 1000-1600°C, after cooling and taking out, an asymmetric struct...

Embodiment 2

[0031] Example 2: Take 1.000 kg of Hastelloy powder with a particle size of 30-100 mesh, add 0.1%-20% of forming agent, mix it in the mixing equipment for 1-3 hours, take it out, and then pass it through the casting machine to obtain powder tubes and sheet green embryos. Degreasing treatment is carried out in a vacuum furnace at a temperature of 300-600°C, and then the powder tube and sheet green body are covered with 40-mesh 316L stainless steel mesh, put into a vacuum furnace, and sintered at 1000-1600°C to obtain a reinforced phase and For powder tubes, sheet support layers and composite support layers with a certain porosity, after the support layer is cooled and taken out, use electrostatic spraying method or ordinary spraying method to spray a 200-600-mesh coating, and control the thickness of the coating to 0.1-0.5mm , and then sintered at 1000-1600 ° C, cooled and taken out to obtain an asymmetric structure powder sintered filter material with a strengthening phase, a...

Embodiment 3

[0032] Example 3: Take 1.000 kg of 30-100-mesh stainless steel 316L powder, add 0.1%-20% forming agent, mix in the mixing equipment for 1-3 hours and take it out, and then pass through the casting machine to obtain powder tubes and sheet green embryos. Degreasing treatment is carried out in a vacuum furnace at 300-600°C, and then the powder tube and sheet green body are coated with 40-mesh 316L stainless steel mesh, put into a vacuum furnace, and sintered at 1000-1600°C to obtain a reinforced phase and a certain porosity powder tube, sheet support layer and composite support layer; after the support layer is cooled and taken out, use electrostatic spraying method or ordinary spraying method to spray 200-600 mesh coating, control the thickness of the coating to 0.1-0.5mm, and then Sintering at 1000~1600℃, cooling and taking out to obtain asymmetric structure powder with strengthening phase

Abstract

The invention relates to a production method for an asymmetric structure powder sintering metal filter pipe and filter element with a strengthening phase. A molding agent is added to metal powder to be mixed, a casting machine is used for obtaining a powder pipe and a sheet forming blank, ungrease treatment is conducted, and then a metal net and mesh wires are laid on the powder pipe and the sheet forming blank and placed in a vacuum furnace for sintering, so that the powder pipe with the strengthening phase and high porosity, a sheet supporting layer and a composite supporting layer are obtained; a coating is sprayed to obtain an asymmetric structure powder sintering filter material with the strengthening phase which is molded and rolled to be of a tube shape for welding, and therefore the asymmetric structure powder sintering metal filter pipe and filter element with the strengthening phase is manufactured. The asymmetric structure powder sintering metal filter pipe and filter element with the strengthening phase has the advantages of being low in filtration resistance, high in filtration flux and porosity and strong in pressure bearing capacity, is applied to S-Zorb devices of Sinopec, increases the filtration flow by 30-50%, and enables the total yield to be more than doubled substantially.

Description

technical field [0001] The invention belongs to the production technical field of oil refining filtration equipment, and relates to a device 101, 102, 103, 104, 105, 110, 111, 108 and a feed oil filter 104 device used in the S-Zorb device of China Petrochemical Co., Ltd. And the production method of the asymmetric structure powder sintered metal filter tube and the filter element with strengthening phase of the hydrogenation F100-B device. Background technique [0002] The study found that the filter element installed in the S-Zorb device has small porosity, high working pressure difference, easy clogging, rapid flow rate attenuation, resulting in frequent backflushing and short life, which directly affects the benefits of the enterprise. [0003] When the existing filter is used to operate in the S-Zorb101 device, when the oil intake is 135-154t / h, the pressure difference is between 19-24KPa; the minimum oil intake is 135.12t / h, the lowest pressure difference is 19.55KPa, ...
